BACKGROUND OF THE INVENTION

I. General

[0003] Alzheimer's disease (AD) is a progressive disease resulting in senile dementia. See generally Selkoe, TINS 16:403 (1993); Hardy et al., WO 92/13069; Selkoe, J. Neuropathol. Exp. Neurol. 53:438 (1994); Duff et al., Nature 373:476 (1995); Games et al., Nature 373:523 (1995). Broadly speaking, the disease falls into two categories: late onset, which occurs in old age (65+ years) and early onset, which develops well before the senile period, i.e., between 35 and 60 years. In both types of disease, the pathology is the same but the abnormalities tend to be more severe and widespread in cases beginning at an earlier age. The disease is characterized by at least two types of lesions in the brain, neurofibrillary tangles and senile plaques. Neurofibrillary tangles are intracellular deposits of microtubule associated tau protein consisting of two filaments twisted about each other in pairs. Senile plaques (i.e., amyloid plaques) are areas of disorganized neuropile up to 150 .mu.m across with extracellular amyloid deposits at the center which are visible by microscopic analysis of sections of brain tissue. The accumulation of amyloid plaques within the brain is also associated with Down's syndrome and other cognitive disorders.

[0004] The principal constituent of the plaques is a peptide termed A.beta. or .beta.-amyloid peptide. A.beta. peptide is a 4-kDa internal fragment of 39-43 amino acids of a larger transmembrane glycoprotein named amyloid precursor protein (APP). As a result of proteolytic processing of APP by different secretase enzymes, A.beta. is primarily found in both a short form, 40 amino acids in length, and a long form, ranging from 42-43 amino acids in length. Part of the hydrophobic transmembrane domain of APP is found at the carboxy end of A.beta., and may account for the ability of A.beta. to aggregate into plaques, particularly in the case of the long form. Accumulation of amyloid plaques in the brain eventually leads to neuronal cell death. The physical symptoms associated with this type of neural deterioration characterize Alzheimer's disease.

[0005] Several mutations within the APP protein have been correlated with the presence of Alzheimer's disease. See, e.g., Goate et al., Nature 349:704 (1991) (valine.sup.717 to isoleucine); Chartier Harlan et al., Nature 353:844 (1991)) (valine.sup.717 to glycine); Murrell et al., Science 254:97 (1991) (valine.sup.717 to phenylalanine); Mullan et al., Nature Genet. 1:345 (1992) (a double mutation changing lysine.sup.595-methionine.sup.596 to asparagine.sup.595-leucine.sup.596). Such mutations are thought to cause Alzheimer's disease by increased or altered processing of APP to A.beta., particularly processing of APP to increased amounts of the long form of A.beta. (i.e., A.beta.1-42 and A.beta.1-43). Mutations in other genes, such as the presenilin genes, PS1 and PS2, are thought indirectly to affect processing of APP to generate increased amounts of long form A.beta. (see Hardy, TINS 20: 154 (1997)).

[0006] Apolipoprotein E (ApoE) encodes a cholesterol-processing protein. The gene, which maps to 19q13.2, has three allelic variants: ApoE4, ApoE3, and ApoE2. The frequency of the apoE4 version of the gene in the general population varies, but is always less than 30% and frequently 8%-15%. ApoE3 is the most common form and ApoE2 is the least common. Persons with one E4 allele usually have about a two to three fold increased risk of developing Alzheimer's disease. Persons with two E4 alleles (usually around 1% of the population) have about a nine-fold increase in risk. Nonetheless, even persons with two E4 alleles do not always get Alzheimer's disease. At least one E4 allele is found in about 40% of patients with late-onset Alzheimer's disease. Genetic screening for E4 has not been routinely performed, because it has not been known how to use this information for a therapeutic regime.

DEFINITIONS

[0075] The term "immunoglobulin" or "antibody" (used interchangeably herein) refers to an antigen-binding protein having a basic four-polypeptide chain structure consisting of two heavy and two light chains, said chains being stabilized, for example, by interchain disulfide bonds, which has the ability to specifically bind antigen. Both heavy and light chains are folded into domains. The term "domain" refers to a globular region of a heavy or light chain polypeptide comprising peptide loops (e.g., comprising 3 to 4 peptide loops) stabilized, for example, by pleated sheet and/or intrachain disulfide bond. Domains are further referred to herein as "constant" or "variable", based on the relative lack of sequence variation within the domains of various class members in the case of a "constant" domain, or the significant variation within the domains of various class members in the case of a "variable" domain. "Constant" domains on the light chain are referred to interchangeably as "light chain constant regions", "light chain constant domains", "CL" regions or "CL" domains). "Constant" domains on the heavy chain are referred to interchangeably as "heavy chain constant regions", "heavy chain constant domains", "CH" regions or "CH" domains). A heavy chain constant region is also commonly understood to refer collectively to the domains present in a full length constant region, which are CH1, hinge, CH2, and CH3 domains in the case of antibodies of IgG isotype. "Variable" domains on the light chain are referred to interchangeably as "light chain variable regions", "light chain variable domains", "VL" regions or "VL" domains). "Variable" domains on the heavy chain are referred to interchangeably as "heavy chain constant regions," "heavy chain constant domains," "CH" regions or "CH" domains).

[0076] The term "region" refers to a part or portion of an antibody chain and includes constant or variable domains as defined herein, as well as more discrete parts or portions of said domains. For example, light chain variable domains or regions include "complementarity determining regions" or "CDRs" interspersed among "framework regions" or "FRs", as defined herein.

[0077] References to an antibody or immunoglobulin include intact antibodies and binding fragments thereof. Typically, fragments compete with the intact antibody from which they were derived for specific binding to an antigen. Fragments include separate heavy and light chains, Fab, Fab'F(ab').sub.2, Fabc, and Fv. Separate chains include NANOBODIES.TM. (i.e., the isolated VH fragment of the heavy chain of antibodies from camels or llamas, optionally humanized). Isolated VH fragments can also be obtained from other sources, such as human antibodies. Fragments are produced by recombinant DNA techniques, or by enzymatic or chemical separation of intact immunoglobulins. The term "antibody" also includes one or more immunoglobulin chains that are chemically conjugated to, or expressed as, fusion proteins with other proteins. The term "antibody" also includes bispecific antibody. A bispecific or bifunctional antibody is an artificial hybrid antibody having two different heavy/light chain pairs and two different binding sites. Bispecific antibodies can be produced by a variety of methods including fusion of hybridomas or linking of Fab' fragments. (See, e.g., Songsivilai & Lachmann, Clin. Exp. Immunol. 79:315-321 (1990); Kostelny et al., J. Immunol. 148, 1547-1553 (1992).)

[0078] "Specific binding" of an antibody means that the antibody exhibits appreciable affinity for antigen or a preferred epitope and, preferably, does not exhibit significant cross reactivity. Appreciable or preferred binding includes binding with an affinity of at least 10.sup.6, 10.sup.7, 10.sup.8, 10.sup.9 M.sup.-1, or 10.sup.10 M.sup.-1. Affinities greater than 10.sup.7 M.sup.-1, preferably greater than 10.sup.8 M.sup.-1 are more preferred. Values intermediate of those set forth herein are also intended to be within the scope of the present invention and a preferred binding affinity can be indicated as a range of affinities, for example, 10.sup.6 to 10.sup.10 M.sup.-1, preferably 10.sup.7 to 10.sup.10 M.sup.-1, more preferably 10.sup.8 to 10.sup.10 M.sup.-1. An antibody that "does not exhibit significant cross reactivity" is one that will not appreciably bind to an undesirable entity (e.g., an undesirable proteinaceous entity). For example, an antibody that specifically binds to A.beta. will appreciably bind A.beta. but will not significantly react with non-A.beta. proteins or peptides (e.g., non-A.beta. proteins or peptides included in plaques). An antibody specific for a preferred epitope will, for example, not significantly cross react with remote epitopes on the same protein or peptide. Specific binding can be determined according to any art-recognized means for determining such binding. Preferably, specific binding is determined according to Scatchard analysis and/or competitive binding assays.

[0079] The term "humanized immunoglobulin" or "humanized antibody" refers to an immunoglobulin or antibody that includes at least one humanized immunoglobulin or antibody chain (i.e., at least one humanized light or heavy chain). The term "humanized immunoglobulin chain" or "humanized antibody chain" (i.e., a "humanized immunoglobulin light chain" or "humanized immunoglobulin heavy chain") refers to an immunoglobulin or antibody chain (i.e., a light or heavy chain, respectively) having a variable region that includes a variable framework region (also known as variable region framework) substantially from a human immunoglobulin or antibody and complementarity determining regions (CDRs) (e.g., at least one CDR, preferably two CDRs, more preferably three CDRs) substantially from a non-human immunoglobulin or antibody (e.g., rodent, and optionally, mouse), and further includes constant regions (e.g., at least one constant region or portion thereof, in the case of a light chain, and preferably three constant regions in the case of a heavy chain). The term "humanized variable region" (e.g., "humanized light chain variable region" or "humanized heavy chain variable region") refers to a variable region that includes a variable framework region (also known as a variable region framework) substantially from a human immunoglobulin or antibody and complementarity determining regions (CDRs) substantially from a non-human immunoglobulin or antibody.

[0080] The phrase "substantially from a human immunoglobulin or antibody" or "substantially human" means that, when aligned to a human immunoglobulin or antibody amino sequence for comparison purposes, the region shares at least 80-90% (e.g., at least 90%), preferably 90-95%, more preferably 95-99% identity (i.e., local sequence identity) with the human framework or constant region sequence, allowing, for example, for conservative substitutions, consensus sequence substitutions, germline substitutions, backmutations, and the like. The introduction of conservative substitutions, consensus sequence substitutions, germline substitutions, backmutations, and the like, is often referred to as "optimization" of a humanized antibody or chain. The phrase "substantially from a non-human immunoglobulin or antibody" or "substantially non-human" means having an immunoglobulin or antibody sequence at least 80-95%, preferably 90-95%, more preferably, 96%, 97%, 98%, or 99% identical to that of a non-human organism, e.g., a non-human mammal.

[0081] Accordingly, all regions or residues of a humanized immunoglobulin or antibody, or of a humanized immunoglobulin or antibody chain, except possibly the CDRs, are substantially identical to the corresponding regions or residues of one or more native human immunoglobulin sequences. The term "corresponding region" or "corresponding residue" refers to a region or residue on a second amino acid or nucleotide sequence which occupies the same (i.e., equivalent) position as a region or residue on a first amino acid or nucleotide sequence, when the first and second sequences are optimally aligned for comparison purposes.

[0082] The terms "humanized immunoglobulin" or "humanized antibody" are not intended to encompass chimeric immunoglobulins or antibodies, as defined infra. Although humanized immunoglobulins or antibodies are chimeric in their construction (i.e., comprise regions from more than one species of protein), they include additional features (i.e., variable regions comprising donor CDR residues and acceptor framework residues) not found in chimeric immunoglobulins or antibodies, as defined herein.

[0083] The term "chimeric immunoglobulin" or antibody refers to an immunoglobulin or antibody whose variable regions derive from a first species and whose constant regions derive from a second species. Chimeric immunoglobulins or antibodies can be constructed, for example by genetic engineering, from immunoglobulin gene segments belonging to different species.

[0084] An "antigen" is an entity (e.g., a proteinaceous entity or peptide) to which an antibody specifically binds.

[0085] The term "epitope" or "antigenic determinant" refers to a site on an antigen to which an immunoglobulin or antibody (or antigen binding fragment thereof) specifically binds. Epitopes can be formed both from contiguous amino acids or noncontiguous amino acids juxtaposed by tertiary folding of a protein. Epitopes formed from contiguous amino acids are typically retained on exposure to denaturing solvents whereas epitopes formed by tertiary folding are typically lost on treatment with denaturing solvents. An epitope typically includes at least 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 amino acids in a unique spatial conformation. Methods of determining spatial conformation of epitopes include, for example, x-ray crystallography and 2-dimensional nuclear magnetic resonance. See, e.g., Epitope Mapping Protocols in Methods in Molecular Biology, Vol. 66, G. E. Morris, Ed. (1996).

[0086] Antibodies that recognize the same epitope can be identified in a simple immunoassay showing the ability of one antibody to block the binding of another antibody to a target antigen, i.e., a competitive binding assay. Competitive binding is determined in an assay in which the immunoglobulin under test inhibits specific binding of a reference antibody to a common antigen, such as A.beta.. Numerous types of competitive binding assays are known, for example: solid phase direct or indirect radioimmunoassay (RIA), solid phase direct or indirect enzyme immunoassay (EIA), sandwich competition assay (see Stahli et al., Methods in Enzymology 9:242 (1983)); solid phase direct biotin-avidin EIA (see Kirkland et al., J. Immunol. 137:3614 (1986)); solid phase direct labelled assay, solid phase direct labelled sandwich assay (see Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Press (1988)); solid phase direct label RIA using I-125 label (see Morel et al., Mol. Immunol. 25(1):7 (1988)); solid phase direct biotin-avidin EIA (Cheung et al., Virology 176:546 (1990)); and direct labelled RIA (Moldenhauer et al., Scand. J. Immunol. 32:77 (1990). Typically, such an assay involves the use of purified antigen bound to a solid surface or cells bearing either of these, an unlabelled test immunoglobulin and a labelled reference immunoglobulin. Competitive inhibition is measured by determining the amount of label bound to the solid surface or cells in the presence of the test immunoglobulin. Usually the test immunoglobulin is present in excess. Usually, when a competing antibody is present in excess, it will inhibit specific binding of a reference antibody to a common antigen by at least 50-55%, 55-60%, 60-65%, 65-70% 70-75% or more.

[0087] An epitope is also recognized by immunologic cells, for example, B cells and/or T cells. Cellular recognition of an epitope can be determined by in vitro assays that measure antigen-dependent proliferation, as determined by .sup.3H-thymidine incorporation, by cytokine secretion, by antibody secretion, or by antigen-dependent killing (cytotoxic T lymphocyte assay).

[0088] Exemplary epitopes or antigenic determinants can be found within the human amyloid precursor protein (APP), but are preferably found within the A.beta. peptide of APP. Multiple isoforms of APP exist, for example APP.sup.695, APP.sup.751 and APP.sup.770. Amino acids within APP are assigned numbers according to the sequence of the APP.sup.770 isoform (see e.g., GenBank Accession No. P05067). The sequences of A.beta. peptides and their relationship to the APP precursor are illustrated by FIG. 1 of Hardy et al., TINS 20, 155-158 (1997). For example, A.beta.42 has the sequence:

TABLE-US-00001 (SEQ ID NO: 1) H.sub.2N-Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu- Val-His-His-Gln-Lys-Leu-Val-Phe-Phe-Ala-Glu-Asp- Val-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Met- Val-Gly-Gly-Val-Val-Ile-Ala-OH.

[0089] Unless otherwise apparent from the context, reference to A.beta. also includes natural allelic variations of the above sequence, particularly those associated with hereditary disease, such as the Arctic mutation, E693G, APP 770 numbering. A.beta.41, A.beta.40 and A.beta.39 differ from A.beta.42 by the omission of Ala, Ala-IIe, and Ala-IIe-Val respectively from the C-terminal end. A.beta.43 differs from A.beta.42 by the presence of a threonine residue at the C-terminus. Preferred epitopes or antigenic determinants, as described herein, are located within the N-terminus of the A.beta. peptide and include residues within amino acids 1-11 of A.beta., preferably from residues 1-10, 1-3, 1-4, 1-5, 1-6, 1-7 or 3-7 of A.beta.42. Additional preferred epitopes or antigenic determinants include residues 2-4, 5, 6, 7 or 8 of A.beta., residues 3-5, 6, 7, 8 or 9 of A.beta., or residues 4-7, 8, 9 or 10 of A.beta.42. Other preferred epitopes occur within central or C-terminal regions as described below.

[0090] An N-terminal epitope of A.beta. means an epitope with residues 1-11. An epitope within a C-terminal region means an epitope within residues 29-43, and an epitope within a central regions means an epitope with residues 12-28

[0091] "Soluble" or "dissociated" A.beta. refers to non-aggregating or disaggregated A.beta. polypeptide.

[0092] "Insoluble" A.beta. refers to aggregating A.beta. polypeptide, for example, A.beta. held together by noncovalent bonds. A.beta. (e.g., A.beta.42) is believed to aggregate, at least in part, due to the presence of hydrophobic residues at the C-terminus of the peptide (part of the transmembrane domain of APP). One method to prepare soluble A.beta. is to dissolve lyophilized peptide in neat DMSO with sonication. The resulting solution is centrifuged to remove any insoluble particulates.

[0093] The term "Fc region" refers to a C-terminal region of an IgG antibody, in particular, the C-terminal region of the heavy chain(s) of said IgG antibody. Although the boundaries of the Fc region of an IgG heavy chain can vary slightly, a Fc region is typically defined as spanning from about amino acid residue Cys226 to the carboxyl-terminus of an IgG heavy chain(s).

[0094] The term "effector function" refers to an activity that resides in the Fc region of an antibody (e.g., an IgG antibody) and includes, for example, the ability of the antibody to bind effector molecules such as complement and/or Fc receptors, which can control several immune functions of the antibody such as effector cell activity, lysis, complement-mediated activity, antibody clearance, and antibody half-life. Effector function can also be influenced by mutations in the hinge region.

[0095] The term "effector molecule" refers to a molecule that is capable of binding to the Fc region of an antibody (e.g., an IgG antibody) including a complement protein or a Fc receptor.

[0096] The term "effector cell" refers to a cell capable of binding to the Fc portion of an antibody (e.g., an IgG antibody) typically via an Fc receptor expressed on the surface of the effector cell including, but not limited to, lymphocytes, e.g., antigen presenting cells and T cells.

[0097] The term "Kabat numbering" unless otherwise stated, is defined as the numbering of the residues as in Kabat et al. (Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md. (1991)), incorporated herein by reference.

[0098] The term "Fc receptor" or "FcR" refers to a receptor that binds to the Fc region of an antibody. Typical Fc receptors which bind to an Fc region of an antibody (e.g., an IgG antibody) include, but are not limited to, receptors of the Fc.gamma.RI, Fc.gamma.RII, and Fc.gamma.RIII subclasses, including allelic variants and alternatively spliced forms of these receptors. Fc receptors are reviewed in Ravetch and Kinet, Annu. Rev. Immunol 9:457-92 (1991); Capel et al., Immunomethods 4:25-34 (1994); and de Haas et al., J. Lab. Clin. Med. 126:330-41 (1995).

[0099] The term "adjuvant" refers to a compound that when administered in conjunction with an antigen augments and/or redirects the immune response to the antigen, but when administered alone does not generate an immune response to the antigen. Adjuvants can augment an immune response by several mechanisms including lymphocyte recruitment, stimulation of B and/or T cells, and stimulation of macrophages.

[0100] The area under the curve (AUC) is the area under the curve in a plot of concentration of drug in plasma against time. In an individual patient, the area under the curve represents the area under the curve based on that patient. In a population of patients, the area under the curve represents the mean area under the curve for a comparable time interval of different patients in the population.

[0101] The mean serum concentration in an individual patient represents the mean concentration of an antibody (or induced antibodies for an active agent) over a period of time. The mean serum concentration in a population of patients represents the mean of the mean serum concentrations of the individual patients over comparable periods of time.

[0102] The maximum serum concentration in an individual patient represents the maximum concentration of an antibody (or induced antibodies for an active agent) during a course of treatment. The maximum serum concentration in a population of individuals represents the mean of maximum concentrations of the antibody or induces antibodies between individuals in the population.

[0103] For brevity, the term "ApoE4 carrier" is sometimes used to refer to patients have in one or two ApoE4 alleles and "ApoE4 noncarrier", ApoE4 non-carrier" or "non-ApoE4 carrier" to refer to patients having zero ApoE4 alleles.

DETAILED DESCRIPTION OF THE INVENTION

I. General

[0104] The invention provides methods of immunotherapy of Alzheimer's and similar diseases in which the regime administered to a patient depends on the ApoE genotype of the patient. The methods are based in part on (1) the observation that certain immunotherapy regimes lead to higher instances in the appearance of vasogenic edema (VE) in patients having an ApoE4 allele (E4) than in patients lacking an E4 allele, and more frequently still in patients having two E4 alleles, and/or (2) the initial observation of differential efficacy in ApoE4 carrier patients compared to ApoE4 non-carrier patients or patients receiving at least six doses compared to patients receiving less than six doses. The results also show that frequency of cases of vasogenic edema increases with dose frequency and amount.

[0105] Although practice of the invention is not dependent on an understanding of mechanism, it is hypothesized that the association of the vasogenic edema with an ApoE4 genotype may stem from a greater deposition of A.beta. deposits and hence induction of a greater clearing response when antibodies bind to the deposits. Clearing of amyloid deposits may lead to vasogenic edema by any or all of several mechanisms. Removal of amyloid from blood vessel walls (vascular amyloid) may cause leakiness of blood vessels; more amyloid in perivascular space may cause slower drainage of interstitial fluid, and/or net increased flow of amyloid from intravascular compartment to brain parenchyma may lead to osmotic gradients. Although vasogenic edema effect is usually asymptomatic and reversible and does not preclude further treatment, it is desirable nevertheless to adjust the therapeutic regime to reduce the risk of vasogenic edema occurring.

[0106] The invention thus provides methods in which the immunotherapy regime is varied, for example to adjust the phagocytic response, depending on the ApoE status of the patient. Although the phagocytic response is useful in clearing amyloid deposits, the response, can optionally be controlled to avoid vasogenic edema. In general, patients having two E4 alleles, who are most susceptible to the vasogenic edema are administered either a lower dose or a lower frequency of the same agent as patients with zero E4 alleles, or are administered a different agent that is less prone to induce a phagocytic response or receive the agent through an alternate mode of administration, such as, for example, subcutaneous administration. Patients with one E4 allele can be treated the same as either patients with zero or two E4 alleles or a treatment can be customized for them in which the dose and/or frequency of administration is intermediate between that administered to patients with zero or two ApoE4 alleles.

II. APOE

[0107] Human ApoE has the UniProtKB/Swiss-Prot entry accession number P02649. The E2, E3, and E4 variants are described in Genomics 3:373-379 (1988), J. Biol. Chem. 259:5495-5499 (1984); and Proc. Natl. Acad. Sci. U.S.A. 82:3445-3449 (1985). Association of the E4 form with late onset Alzheimer's disease has been reported by e.g., Corder, Science 261, 921-3 (1993); Farrer, JAMA, 278, 1349-56 (1997); and Saunders, Neurology 43, 1467-72 (1993). The allelic forms present in any individual can be determined by many conventional techniques, such as direct sequencing, use of GeneChip.RTM. arrays or the like, allele-specific probes, single-base extension methods, allelic specific extension. Allelic forms can also be determined at the protein level by ELISA using antibodies specific for different allelic expression products. Kits for genetic and immunological analysis are commercially available (e.g., Innogenetics, Inc.; Graceful Earth, Inc.). Determination of allelic forms are usually made in vitro, that is, on samples removed and never returned to a patient.

III. Different Strategies for Treating or Monitoring Depending on ApoE

A. Different Treatment Regimes

[0108] Some immunotherapy regimes for immunotherapy of Alzheimer's and other diseases have been associated with vasogenic edema (VE) in the brain of some patients. Generally, the incidence of VE is greater in ApoE4 carriers than in ApoeE4 non-carriers and in patients receiving higher doses of certain agents in certain immunotherapy regimes. VE has been observed on magnetic resonance imaging (MRI) as high signal intensities on the fluid-attenuated inversion recovery (FLAIR) sequence involving cerebral abnormalities and gyral swelling. VE generally is observed after the first or second administration of the immunotherapeutic agent, although it has been observed after the third or fourth administration. Most patients with VE discovered on MRI are asymptomatic. VE is heterogeneous on presentation, and MRI findings in a particular patient may vary over time. The gyral swelling and to some extent, the larger magnetic resonance (MR) changes seen on FLAIR differentiate VE from the commonly observed white matter changes seen on FLAIR in both normal elderly and Alzheimer's disease patients (Hentschel et al., 2005; de Leeuw et al. 2001).

[0109] Vasogenic edema (VE) is characterized by an increase in extracellular fluid volume due to increased permeability of brain capillary endothelial cells to macromolecular serum proteins (e.g., albumin). VE may be the result of increased brain capillary permeability. Clinical symptoms observed in patients with VE, when existent, are varied and to date have been largely mild in nature. Of the cases of VE observed on regularly scheduled MRI, the majority of patients are asymptomatic. Clinical observations associated with the symptomatic cases of VE have included altered mental states (e.g., increased confusion, lethargy, disorientation, and hallucinations), vomiting, headache, gait difficulties, visual disturbances, fatigue, irritability, ataxia, decreased appetite, and diarrhea.

[0110] As summarized above, the invention provides different treatment regimes depending on whether a patient has zero, one or two E4 alleles. Thus, in a population of treated individuals, those having zero E4 alleles can be treated differently from those having two alleles. Those having one E4 allele can be treated differently (in an intermediate fashion) to those with either zero or two E4 alleles or can be grouped with individuals having zero or two the E4 allele in any of the regimes that follow. It follows that individuals having one E4 allele can be treated differently than individuals with zero alleles and/or that individual with two ApoE4 alleles can be treated differently than individuals with one ApoE4 allele. Ongoing experience with some immunotherapeutic agents suggests that VE is more likely to occur at doses greater than 5 mg/kg (see PCT/US07/09499).

[0111] In some methods, ApoE4 status is the only genetic marker determining different treatment regimes in different patients. In other methods, differential treatment regimes can be based on ApoE4 in combination with other genetic markers associated with Alzheimer's disease susceptibility or resistance.

[0112] A population of treated individuals optionally has sufficient total number of patients and sufficient numbers of subpopulations with different numbers of ApoE4 alleles that an association between different treatment regimes and different ApoE4 alleles can be seen relative to a random assignment of the different regimes with a statistical confidence of at least 95%. For example, the treated population can consist of at least 100, 500 or 1000 individuals of who 10-70% and more typically 30-50% have at least one an ApoE4 allele. A treated population can also (i.e., optionally) be recognized as the total population treated with a particular drug produced by a particular manufacturer.

[0113] In some methods, as discussed in greater detail below, individuals having zero ApoE4 alleles are administered an agent in a regime designed to achieve efficacy as assessed from one or more clinical endpoints, such as, for example, cognitive measures (e.g., ADAS-cog, NTB, DAD, MMSE, CDR-SB, NPI), biomarkers (e.g., CSF tau), and brain volume (e.g., BBSI, VBSI), as well as other parameters, such as, for example desirable safety, pharmacokinetics and pharmacodynamics. In some methods, one or two E4 alleles are administered a reduced dose and/or frequency of the same agent as individuals with zero E4 alleles. A goal of such method is to deliver a reduced mean serum concentration of the agent over a period of time (reduced area under the curve) and/or to reduce the maximum peak concentration. This can be accomplished for example, by reducing the dose and administering at the same frequency, or reducing the frequency and administering at the same dose or administering at reduced dose and frequency. If the dose is reduced but the frequency kept constant, the dose is usually reduced between 10-90%, often about 30-75 or 40-60%. If the frequency is reduced, but the dose kept constant, then the frequency is typically reduced between two and five fold. Sometimes, the frequency is reduced by simply omitting an occasional dose or two consecutive doses from the regime administered to patients with zero ApoE4 alleles. Such doses can for example be omitted during the period a patient is experiencing vasogenic edema.

[0114] In other methods, individual having one or two E4 alleles are administered a reduce dose of the agent at an increased frequency relative to individuals having zero E4 alleles. For, example, the dose can be halved and the frequency doubled. In such methods, the total drug delivered to the two subpopulations over time (i.e., area under the curve) can be the same within experimental error, but the maximum plasma concentration is lower in individuals having two E4 alleles. For example, in patients having one or two E4 alleles the maximum serum concentration of antibody is preferably below 14 .mu.g/ml and for patients having zero alleles, the maximum serum concentration of antibody is preferably below 28 .mu.g/ml.

[0115] In other methods, treatment is administered at different stages relative to disease progression depending on ApoE4 status. In such methods, treatment is administered earlier in patients having two ApoE4 alleles relative to patients having zero ApoE4 alleles or in patients having one ApoE4 allele relative to patients having zero ApoE4 alleles and/or in patients having two ApoE4 alleles relative to patients having one ApoE4 allele. Disease progression can be measured by e.g., the MMSE scale on which a score of 27 to 20 is considered normal, and 20-26 considered mild Alzheimer's. Thus, for example, the mean MMSE score of non-ApoE4 carriers on commencement of treatment can be higher than that of ApoE4 carriers (patients with one or two ApoE4 alleles). Optionally, treatment of ApoE4 carriers can be begun prophylactically before clinical symptoms are evident. Such patients can be identified by screening populations for ApoE4 status. Treatment can be commenced on detecting such status or subsequently when the patient reaches a certain age (e.g., 55, 60 or 65 years) when there is a high risk of Alzheimer's developing. Although understanding of mechanism is not required for practice of such methods, it is believed that early treatment of ApoE4 carriers may be beneficial because the ApoE4 allele reduces capacity to repair neuronal damage, and/or because deposition of A.beta. is greater in such patients.

[0116] In some methods, treatment is administered by a different route in patients having zero ApoE4 alleles and patients having one ApoE4 allele and/or patients having two ApoE4 alleles. For example, treatment can be administered intravenously in patients having zero ApoE4 alleles and subcutaneously in patients having one or two alleles. The dosage is typically greater and/or frequency of administration less in such non-ApoE4 carrier patients relative to ApoE4 carrier patients.

[0117] In some methods, a positive response to treatment (i.e., inhibition of cognitive decline or inhibition of decline in brain volume) takes longer to develop in ApoE4 carriers than non-carriers. The greater time may reflect reduced capacity for neuronal repair and/or greater amyloid burden in such patients; and/or use of a less potent treatment regime. In such methods, treatment can be administered for at least one year and optionally at least 2, 3 or 4 years before ceasing treatment for lack of effect. In some methods, treatment is administered for at least six quarterly administrations.

[0118] As noted, agents are sometimes provided with a label contraindicating use in ApoE4 carriers. Such agents can be used in methods of treatment in which only non-ApoE4 carriers receive an agent of the invention (i.e., an antibody that binds to A.beta. or an agent that induces such an antibody). In such methods ApoE4 carriers do not receive an antibody that binds to A.beta. or an agent that induces such an antibody but can receive other treatments such memantine.

[0119] Methods in which dose and/or frequency of administration are reduced depending on ApoE4 are most useful for agents that initiate a clearing response against amyloid deposits. In general, such agents are antibodies binding to an epitope within A.beta. 1-11, and which have an Fc region, or fragments of A.beta. that induce such antibodies (i.e., contain an epitope within A.beta. 1-11). Antibodies binding to epitopes within central or C-terminal regions of A.beta. usually bind predominantly to soluble forms of A.beta. rather than amyloid deposits, and thus initiate little, if any clearing response against amyloid deposits, particularly dense or vascular deposits.

[0120] Examples of suitable dosages ranges and frequencies for administration are provided below. Different dosages and/or frequencies of administration for patients with different E4 status can be selected from within such ranges of dose and frequency. For example, patients with one or two E4 alleles can be administered a dose of 0.1 to 1 mg/kg antibody by intravenous infusion every thirteen weeks, and patients with zero E4 alleles can be administered a dose of 1 to 2 mg/kg every thirteen weeks. Optionally, patients with two E4 alleles are administered a dose of 0.15 to 0.5 mg/kg, patients with one E4 allele are administered a dose of 0.15 to 1 mg/kg (e.g., 0.5 to 1 mg/kg) and patients with zero E4 alleles are administered a dose of 0.15-2 mg/kg (e.g., 1-2 mg/kg) every thirteen weeks. In a preferred regime, patients with one or two E4 alleles are administered a dose of 0.5 mg/kg of an antibody binding to an epitope within residues 1-11 of A.beta. (e.g., bapineuzumab) and patients with zero E4 alleles a dose of 2 mg/kg. The doses are administered intravenously at quarterly intervals until vasogenic edema appears (if it does). After vasogenic edema appears, the next dose is missed and thereafter, patients return to the quarterly dosing schedule at a lower dose of 0.15 mg/kg. If vasogenic edema appears again treatment can be terminated. Patients with zero E4 alleles are administered a dose of 0.5-2 mg/kg, with individually patients with zero E4 alleles optionally receiving doses of 0.5 mg/kg, 1.0 mg/kg, 1.5 mg/kg and 2.0 mg/kg.

[0121] As another example, patients with two E4 alleles are given a first dose of 0.5 mg/kg, and subsequent doses of 1 mg/kg. Alternatively, patients with two E4 alleles are given a first dose of 0.5 mg/kg, second and third doses of 1 mg/kg and subsequent doses of 2.0 mg/kg.

[0122] As another example, patients with zero E4 alleles can be administered a dose of 0.015-0.2 mg/kg antibody subcutaneously once per week and patients with two E4 alleles can be administered the same dose every two weeks. Equivalent regimes to any of the above can be devised by varying either the amount or frequency or route of administration to deliver the same area under the curve (i.e., mean dose integrated with time) of antibody to the serum.

[0123] In some methods, patients with one or two E4 alleles are administered agent to achieve a lower mean serum concentration of antibody over time than patients with zero E4 alleles. The lower mean serum concentration is maintained over a period of at least one or threes month, and usually three months to one year, or indefinitely. The mean serum concentration of all such patients is preferably within the range 2-7 .mu.g antibody/ml serum with that for patients with one or two E4 alleles being lower than that for patients with zero E4 alleles. For example patients with zero E4 alleles can be administered to achieve a mean serum concentration of antibody within a range of 4.5-7 .mu.g antibody/ml and patients with one or two E4 alleles can be administered agent to achieve a mean serum concentration in the range of 2-4.5 .mu.g antibody/ml.

[0124] In such methods, individuals within any subpopulation defined by presence of two, one or zero E4 alleles are usually administered the same regime. However, the regime can also be customized for individuals within a subpopulation. In this case, the mean dose and/or frequency and/or average serum concentration and/or maximum concentration of agent or antibodies induced by the agent in a subpopulation of individuals with two E4 alleles is lower than that of individuals having zero E4 alleles.

[0125] In some methods, a different agent is administered to individuals with two E4 alleles than individuals with zero E4 alleles. The different agents usually differ in their capacity to induce a clearing response against amyloid deposits (i.e., preexisting deposits). Such a capacity can be tested, for example, in an ex vivo clearing assay as described by U.S. Pat. No. 6,750,324. In brief, an antibody and microglial cells are incubated with an amyloid deposit from a diseased Alzheimer's patient or transgenic mouse model, and the clearing reaction is monitored using a labelled antibody to A.beta.. Clearing capacity of active agents can be similarly tested using sera induced by the active agent as a source of antibody for the assay. Clearing capacity of both passive and active agents can also be evaluated in a transgenic mouse model as also described U.S. Pat. No. 6,750,324 or in a human patient by MRI monitoring. Optionally, the clearing response is measured in an assay that distinguishes between compact and diffuse amyloid deposits. Differences in clearing capacity of some antibodies are more evident or only evident when the comparison is made with respect to clearing capacity of compact amyloid deposits. Optionally, the clearing response is evaluated from a reduction in clearing of vascular amyloid of a mutated antibody relative to an isotype matched otherwise-identical antibody. Vascular amyloid clearing can be assessed by a statistical significant difference between populations of animal models or human patients treated with a mutated antibody and an otherwise-identical isotype-matched antibody without the mutations.

[0126] Additionally or alternatively to assays measuring a clearing response, some antibodies suitable for use in the methods of the invention can be recognized by reduced binding to C1q and/or to Fc.gamma. receptor(s). Capacity to bind C1q and/or an Fc.gamma. receptor can be reduced by mutations near the hinge region of a heavy chain as discussed in more detail below. Reduced capacity can be determined, for example, by comparing a mutated antibody with an isotype matched otherwise identical antibody lacking the mutation(s) present in the mutated antibody (i.e., having residues from a wild type human constant region (e.g., bapineuzumab vs. AAB-003), or by comparing otherwise identical antibodies having different isotypes (e.g., human IgG1 versus human IgG4).

[0127] Some antibodies having reduced capacity to bind C1q and/or Fc.gamma. receptor(s) reduce micro-hemorrhaging relative to isotype matched controls but retain at least some activity in inhibiting cognitive decline and/or clearing amyloid deposits. In some antibodies, reduced amyloid clearing capacity is mainly associated with reduced clearing capacity of vascular amyloid and/or compact amyloid deposits and not with diffuse amyloid deposits. Such antibodies offer a potentially improved efficacy:side-effects profile, particularly for use in ApoE4 carriers.

[0128] Antibodies having reduced binding to C1q and/or an Fc.gamma. receptor can be used in differential methods of treatment as described above. For example, an antibody with reduced binding to C1q and/or and Fc.gamma. receptor can be administered to patients having one or two ApoE4 alleles and an otherwise identical antibody without the mutation(s) to patients with zero ApoE4 alleles. Alternatively, an antibody with reduced binding to C1q and/or an Fc.gamma. receptor can be administered to patients irrespective of the number of ApoE4 alleles.

[0129] Antibodies with constant regions mutated to reduce C1q and/or Fc.gamma. receptor binding are sometimes administered at higher dosages than otherwise identical antibodies without the mutation. For some such antibodies, the dosage can be adjusted upward to achieve an equivalent therapeutic effect with reduced side effects.

[0130] Clearing capacity is affected both by the epitope specificity of an antibody (or antibodies induced by a fragment for active administration) and on the presence of, and type of effector function of the antibody, in particular by the capacity of the Fc region if present to bind to Fc.gamma. receptors. Although clearing amyloid deposits is one useful mechanism of action, agents that lack the capacity to clear deposits can be useful by other mechanisms, such as binding to soluble A.beta. and/or soluble oligomeric forms of A.beta.. Such binding may reduce toxicity of such species and/or inhibit their aggregating to form deposits among other possible mechanisms.

[0131] Agents with a propensity to induce such a clearing response include antibodies binding to an epitope within residues 1-11 and particularly 1-7 of A.beta., particularly such antibodies having a human IgG1 isotype, which interacts most strongly with Fc.gamma. receptors. Fragments of A.beta. that contain epitopes within residues 1-11 and particularly 1-7 are similarly effective in inducing a clearing response. Optionally, agents which initiate a clearing response, can be provided with a label contraindicating use to patients with one or two ApoE4 alleles. Agents with less or no propensity to induce a clearing response include antibodies to A.beta. that have isotypes other than human IgG1, antibodies that lack an Fc region (e.g., Fab fragments, Fv fragments, or Nanobodies), or antibodies with Fc regions mutated by genetic engineering to reduce interactions with Fc.gamma. receptors. Such agents also include antibodies that specifically bind to an epitope within a region of A.beta. other than residues 1-11, (i.e., to a mid-epitope or C-terminal epitope, as described above) and antibodies that specifically bind to soluble or oligomeric forms of A.beta. without binding to amyloid deposits. Such agents also include fragments of A.beta. that lack epitopes within residues 1-11 of A.beta.. In such methods, individuals having two E4 alleles are administered an agent with a lower tendency to induce a phagocytic clearing response than individuals having zero alleles. For example, individuals having zero E4 alleles can be administered an antibody binding to an epitope within residues 1-11 of A.beta. and having human IgG1 isotype and individuals having two E4 alleles can be administered the same antibody except that the antibody is a Fab fragment or has an isotype other than human IgG1 or has an engineered Fc region to reduce binding to Fc.gamma. receptors. The agent administered to individuals having two E4 alleles can also be an antibody to a mid or C-terminal epitope of A.beta. or a fragment of A.beta. from a mid or C-terminal region (i.e., lacking an epitope from within A.beta. 1-11).

[0132] In some methods, patients with two E4 alleles are administered an antibody having an epitope within a mid or C-terminal regions for one or more initial doses and an antibody having an epitope within an N-terminal region for subsequent doses. Such an antibody can be a humanized 266 antibody, a humanized 2H6 antibody, a deglycosylated humanized 2H6 antibody or RN1219. Such an antibody can also be a humanized antibody that specifically binds to an epitope within A028-40 or A.beta.33-40. The initial doses preferably consist of 1, 2 or 3 doses. Patients having zero alleles can be administered an antibody having an epitope within an N-terminal region.

[0133] The different regimes administered to different patients depending on their E4 status can be maintained indefinitely. However, such is not usually necessary. It has been found that the vasogenic edema side effect associated with the E4 allele usually occurs by the third dose, if at all. Thus, once patients have received about 2-3 doses of treatment, patients having one or two ApoE4 alleles who have not developed vasogenic edema probably will not develop it, and can thereafter, if desired, be treated by the same regime as patients having zero E4 alleles. Likewise patients with one or two ApoE4 alleles who do develop vasogenic edema notwithstanding the present differential treatment regime usually resolve this condition and can thereafter, if desired, be treated in similar fashion to patients having zero E4 alleles. Optionally, the dose is titrated up after recovering from vasogenic edema to that used for non-carriers.

[0134] Vasogenic edema typically resolves of its own accord. However, resolution can be facilitated if desired by administration of a corticosteroid.

[0135] Agents can be packaged with labels indicating differential treatment procedures dependent on ApoE4 status consistent with any of the above regimes or combinations thereof.

B. Different Monitoring Regimes

[0136] Alternatively or additionally, the invention provides different monitoring regimes for patients depending on their E4 status. Vasogenic edema is an increase in brain volume from leakage of plasma into the interstitial space. Once extravasated, fluid is retained outside the vasculature, mostly in the white matter of the brain. Vasogenic edema can be monitored by brain imaging particularly by MRI, Positron Emission Tomography (PET Imaging) or Fluid Attenuated Inversion Recovery (FLAIR) sequence imaging (See Pediatric Neurology, 20(3):241-243; AJNR, 26:825-830; NEJM, 334(8):494-500; Pediatr Nephrol, 18:1161-1166; Internal Medicine Journal, 35:83-90; JNNP, 68:790-79 1; AJNR, 23:1038-1048; Pak J Med Sci, 21(2):149-154 and, AJNR, 21:1199-1209). Vasogenic edema presents with a high signal intensity in white matter. The vasogenic edema observed is often asymptomatic but can also be accompanied by headache, nausea, vomiting, confusion, seizures, visual abnormalities, altered mental functioning, ataxia, frontal symptoms, parietal symptoms, stupor, and focal neurological signs.

[0137] According to the present methods, patients with two E4 alleles can be subjected to brain imaging more frequently than patients having zero E4 alleles. For example, patients with two copies of E4 can be imaged before beginning treatment and quarterly thereafter, whereas patients with zero E4 alleles can be imaged before beginning treatment and annually or biannually thereafter. Alternatively, brain imaging can be omitted altogether in patients having zero E4 alleles. Patients having one E4 allele can be imaged with intermediate frequency between patients having zero and two E4 alleles, or can be grouped with patients having either zero or two E4 alleles. It follows that patients with one E4 allele can be monitored differently (e.g., more frequently) than patients with zero E4 alleles and patients with two E4 alleles can be monitored differently (e.g., more frequently) than patients with one E4 allele.

[0138] In patients developing vasogenic edema, monitoring can be continued during the vasogenic edema and for about a year after symptoms resolve. Thereafter, assuming no neurologic findings, monitoring can optionally be performed six monthly or annually.

[0139] Agents can be packaged with labels indicating differential monitoring procedures dependent on ApoE4 status consistent with any of the above regimes or combinations thereof.

C. Universal Treatment or Monitoring Regimes

[0140] Although ApoE4 carriers and non-carriers can have different responses to treatment as discussed above, and some treatment regimes that are safe and effective in ApoE4 carriers are also safe and effective, although not necessarily optimal, in non-ApoE4 carriers and can be used in both types of patients without regard to ApoE status of the patients. In some such regimes, the agent is an antibody that binds to an N-terminal epitope of A.beta. having mutation(s) in its constant region that reduce binding to an Fc.gamma. receptor and/or C1q. AAB-003 is an example of such an antibody. In other regimes, the dose and/or frequency and/or the maximal serum concentration and/or mean serum concentration of an administered or induced antibody are constrained within limits as described in PCT/US2007/009499 and further summarized below to reduce the risk of vasogenic edema.

IV. Agents

A. Antibodies

[0141] A variety of antibodies to A.beta. have been described in the patent and scientific literature for use in immunotherapy of Alzheimer's disease, some of which are in clinical trials (see, e.g., U.S. Pat. No. 6,750,324). Such antibodies can specifically bind to an N-terminal epitope, a mid (i.e., central)-epitope or a C-terminal epitope as defined above. Some antibodies are N-terminal specific (i.e., such antibodies specifically bind to the N-terminus of A.beta. without binding to APP). As noted above antibodies binding to epitopes within residues 1-10, 1-3, 1-4, 1-5, 1-6, 1-7 or 3-7 of A.beta.42 or within residues 2-4, 5, 6, 7 or 8 of A.beta., or within residues 3-5, 6, 7, 8 or 9 of A.beta., or within residues 4-7, 8, 9 or 10 of A.beta.42 can be used. Some antibodies are C-terminal specific (i.e., specifically bind to a C-terminus of A.beta. without binding to APP) Antibodies can be polyclonal or monoclonal. Polyclonal sera typically contain mixed populations of antibodies specifically binding to several epitopes along the length of APP. However, polyclonal sera can be specific to a particular segment of A.beta. such as A.beta. 1-11) without specifically binding to other segments of A.beta.. Preferred antibodies are chimeric, humanized (including veneered antibodies) (see Queen et al., Proc. Natl. Acad. Sci. USA 86:10029-10033 (1989) and WO 90/07861, U.S. Pat. No. 5,693,762, U.S. Pat.

[0142] 3D6 antibody, 10D5 and variants thereof are examples of antibodies that can be used. Both are described in US 20030165496, US 20040087777, WO 02/46237, and WO 04/080419, WO 02/088306 and WO 02/088307. 10D5 antibodies are also described in US 20050142131. Additional 3D6 antibodies are described in US 20060198851 and PCT/US05/45614. 3D6 is a monoclonal antibody (mAb) that specifically binds to an N-terminal epitope located in the human .beta.-amyloid peptide, specifically, residues 1-5. By comparison, 10D5 is a mAb that specifically binds to an N-terminal epitope located in the human .beta.-amyloid peptide, specifically, residues 3-6. A cell line producing the 3D6 monoclonal antibody (RB96 3D6.32.2.4) was deposited with the American Type Culture Collection (ATCC), Manassas, Va. 20108, USA on Apr. 8, 2003 under the terms of the Budapest Treaty and assigned accession number PTA-5130.

[0224] Any of the antibodies or antibody fragments described herein can be designed or prepared using standard methods, as disclosed, e.g., in US 20040038304, US 20070020685, US 200601660184, US 20060134098, US 20050255552, US 20050130266, US 2004025363, US 20040038317, US 20030157579, and U.S. Pat. No. 7,335,478.

[0225] Any of the antibodies described above can be produced with different isotypes or mutant isotypes to control the extent of binding to different Fc.gamma. receptors. Antibodies lacking an Fc region (e.g., Fab fragments) lack binding to Fc.gamma. receptors. Selection of isotype also affects binding to Fc.gamma. receptors. The respective affinities of various human IgG isotypes for the three Fc.gamma. receptors, Fc.gamma.RI, Fc.gamma.RII, and Fc.gamma.RIII, have been determined. (See Ravetch & Kinet, Annu. Rev. Immunol. 9, 457 (1991)). Fc.gamma.RI is a high affinity receptor that binds to IgGs in monomeric form, and the latter two are low affinity receptors that bind IgGs only in multimeric form. In general, both IgG1 and IgG3 have significant binding activity to all three receptors, IgG4 to Fc.gamma.RI, and IgG2 to only one type of Fc.gamma.RII called IIa.sub.LR (see Parren et al., J. Immunol. 148, 695 (1992). Therefore, human isotype IgG1 is usually selected for stronger binding to Fc.gamma. receptors is desired, and IgG2 is usually selected for weaker binding.

[0226] Mutations on, adjacent, or close to sites in the hinge link region (e.g., replacing residues 234, 235, 236 and/or 237 with another residue) in all of the isotypes reduce affinity for Fc.gamma. receptors, particularly Fc.gamma.RI receptor (see, e.g., U.S. Pat. No. 6,624,821). Optionally, positions 234, 236 and/or 237 are substituted with alanine and position 235 with glutamine. (See, e.g., U.S. Pat. No. 5,624,821.) Position 236 is missing in the human IgG2 isotype. Exemplary segments of amino acids for positions 234, 235 and 237 for human IgG2 are Ala Alai Gly, Val Ala Ala, Ala Ala Ala, Val Glu Ala, and Ala Glu Ala. A preferred combination of mutants is L234A, L235A, and G237A for human isotype IgG1. A particular preferred antibody is bapineuzumab having human isotype IgG and these three mutations of the Fc region. Other substitutions that decrease binding to Fc.gamma. receptors are an E233P mutation (particularly in mouse IgG1) and D265A (particularly in mouse IgG2a). Other examples of mutations and combinations of mutations reducing Fc and/or C1q binding are described in the Examples (E318A/K320A/R322A (particularly in mouse IgG1), L235A/E318A/K320A/K322A (particularly in mouse IgG2a). Similarly, residue 241 (Ser) in human IgG4 can be replaced, e.g., with proline to disrupt Fc binding.

[0227] Additional mutations can be made to the constant region to modulate effector activity. For example, mutations can be made to the IgG2a constant region at A330S, P331S, or both. For IgG4, mutations can be made at E233P, F234V and L235A, with G236 deleted, or any combination thereof. IgG4 can also have one or both of the following mutations S228P and L235E. The use of disrupted constant region sequences to modulate effector function is further described, e.g., in WO 06/118,959 and WO 06/036291.

[0228] Additional mutations can be made to the constant region of human IgG to modulate effector activity (see, e.g., WO 06/03291). These include the following substitutions: (i) A327G, A330S, P331S; (ii) E233P, L234V, L235A, G236 deleted; (iii) E233P, L234V, L235A; (iv) E233P, L234V, L235A, G236 deleted, A327G, A330S, P331S; and (v) E233P, L234V, L235A, A327G, A330S, P331S to human IgG1.

[0229] The affinity of an antibody for the FcR can be altered by mutating certain residues of the heavy chain constant region. For example, disruption of the glycosylation site of human IgG1 can reduce FcR binding, and thus effector function, of the antibody (see, e.g., WO 06/036291). The tripeptide sequences NXS, NXT, and NXC, where X is any amino acid other than proline, are the enzymatic recognition sites for glycosylation of the N residue. Disruption of any of the tripeptide amino acids, particularly in the CH2 region of IgG, will prevent glycosylation at that site. For example, mutation of N297 of human IgG1 prevents glycosylation and reduces FcR binding to the antibody.

[0230] The sequences of several exemplary humanized 3D6 antibodies and their components parts are shown below. Human constant regions show allotypic variation and isoallallotypic variation between different individuals, that is, the constant regions can differ in different individuals at one or more polymorphic positions. Isoallotypes differ from allotypes in that sera recognizing an isoallotype binds to a non-polymorphic region of a one or more other isotypes. The allotype of the IgG1 constant region shown below is 3D6 (AAB-001) is G1mz which has Glu at position 356 and Met at position 358. The allotype of the kappa constant region shown below is Km3, which has an Ala at position 153 and a Val at position 191. A different allotye Km(1) has Val and Leu at positions 153 and 191 respectively. Allotypic variants are reviewed by J Immunogen 3: 357-362 (1976) and Loghem,. Monogr Allergy 19: 40-51 (1986). Other allotypic and isoallotypic variants of the illustrated constant regions are included. Also included are constant regions having any permutation of residues occupying polymorphic positions in natural allotypes. Examples of other heavy chain IgG1 allotypes include: G1m(f), G1m(a) and G1m(x). G1m(f) differs from G1m(z) in that it has an Arg instead of a Lys at position 214. G1m(a) has amino acids Arg, Asp, Glu, Leu at positions 355-358.

[0255] In some antibodies, positions 234, 235, and 237 of a human IgG heavy chain constant region can be AAA respectively, LLA respectively, LAG respectively, ALG respectively, AAG respectively, ALA respectively, or LAA respectively. As shown above, AAB-003 is an L234A, L235A, and G237A variant of bapineuzumab (i.e., having identical amino acid sequences to bapineuzumab except for the L234A, L235A, and G237A mutations, alanine (A) being the variant amino acid). Like bapineuzumab, AAB-003 has a full-length human kappa light chain constant region and a full-length human IgG1 heavy chain constant region (in either bapineuzumab or AAB-003, a C-terminal lysine residue is sometimes cleaved intracellularly and is sometimes missing from the final product).

[0256] Although the three mutations in AAB-003 are close to the hinge region rather than the complement binding region, AAB-003 has reduced binding to both Fc.gamma. receptors and to C1q, relative to bapineuzumab. Thus, the AAB-003 antibody has reduced capacity to induce both phagocytosis and the complement cascade. Furthermore, AAB-003 displays less binding to human Fc.gamma.RII than an otherwise identical antibody with fewer than the three mutations present in AAB-003 (e.g., one with substitutions at residues 234 and 237), indicating that all three mutations in the AAB-003 Fc region contribute to reducing effector function. Mutation of the heavy chain constant region to reduce interaction with Fc.gamma. receptor(s) and or C1q can reduce microhemorrhaging in a mouse model without eliminating useful activities. Microhemorraghing in mice is one factor that may contribute to vasogenic edema occurring in humans. Antibodies bearing such mutations retain the ability to inhibit cognitive decline as well as ability to clear amyloid deposits.

[0257] Similarly heavy chain constant region mutants can also be combined with the variable region sequences described above, e.g., for humanized 12A11 and 12B4 antibodies. The following table shows exemplary combinations of heavy chain variable regions and heavy chain constant regions with mutation(s) for antibodies described above. The heavy chains shown in the table for a particular antibody e.g., 12A11, can be paired with any of the light chain variable regions described above for that antibody linked to a light chain constant region (e.g., a human kappa light chain constant region as follows:

[0258] Amino acids in the constant region are numbered by alignment with the human antibody EU (see Cunningham et al., J. Biol. Chem., 9, 3161 (1970)). That is, the heavy and light chains of an antibody are aligned with the heavy and light chains of EU to maximize amino acid sequence identity and each amino acid in the antibody is assigned the same number as the corresponding amino acid in EU. The EU numbering system is conventional (see generally, Kabat et al., Sequences of Protein of Immunological Interest, NIH Publication No. 91-3242, US Department of Health and Human Services (1991)).

[0259] The affinity of an antibody for complement component C1q can be altered by mutating at least one of the amino acid residues 318, 320, and 322 of the heavy chain to a residue having a different side chain. Other suitable alterations for altering, e.g., reducing or abolishing, specific C1q-binding to an antibody include changing any one of residues 318 (Glu), 320 (Lys) and 322 (Lys), to Ala. C1q binding activity can be abolished by replacing any one of the three specified residues with a residue having an inappropriate functionality on its side chain. It is not necessary to replace the ionic residues only with Ala to abolish C1q binding. It is also possible to use other alkyl-substituted non-ionic residues, such as Gly, Ile, Leu, or Val, or such aromatic non-polar residues as Phe, Tyr, Trp and Pro in place of any one of the three residues in order to abolish C1q binding. In addition, it is also be possible to use such polar non-ionic residues as Ser, Thr, Cys, and Met in place of residues 320 and 322, but not 318, to abolish C1q binding activity. Replacement of the 318 (Glu) residue by a polar residue may modify but not abolish C1q binding activity. Replacing residue 297 (Asn) with Ala results in removal of lytic activity while only slightly reducing (about three fold weaker) affinity for C1q. This alteration destroys the glycosylation site and the presence of carbohydrate that is required for complement activation. Any other substitution at this site also destroys the glycosylation site.

[0260] Additional mutations that can affect Clq binding to the constant region of human IgG1 include those described, e.g., in WO 06/036291. In this case, at least one of the following substitutions can be made to reduce C1q binding: D270A, K322A, P329A, and P311S. Each of these mutations, including those at residues 297, 318, and 320 can be made individually or in combination.

[0261] Antibodies with heavy chain constant region mutations that reduce binding to Fc.gamma. receptor(s) and/or C1q can be used in any of the methods of the invention. Preferably, such antibodies have reduced binding relative to an otherwise identical antibody lacking the mutation of at least 50% to at least one Fc.gamma. receptor and/or to C1q.

B. A.beta. Fragments

[0262] Numerous fragments of A.beta. have been now been described in the scientific and patent literature as agents for active immunotherapy (see, e.g., U.S. Pat. No. 6,750,324, US 20040213800; US 20070134762). In general, fragments including an epitope within residues 1-11 of A.beta. induce antibodies that bind Fc.gamma. receptors and induce a clearing response against amyloid deposits, whereas fragments lacking an epitope within residues 1-11 of A.beta. induce antibodies that bind preferentially or exclusively to soluble forms of A.beta. rather than plaques and induces little if any clearing response against amyloid deposits.

[0263] Preferred fragment for inducing antibodies that bind to amyloid deposits and induce a clearing response are N-terminal fragments beginning at residues 1-3 of A.beta. and ending at residues 7-11 of A.beta.. Exemplary N-terminal fragments include A.beta.1-5, 1-6, 1-7, 1-10, 3-7, 1-3, and 1-4 with 1-7 being particularly preferred. A class of exemplary fragments includes fragments beginning at a residue between 1-3 (inclusive) and ending at a residue between 7-11 (inclusive).

[0264] Preferred fragments for inducing antibodies to soluble A.beta., which induce little, if any, clearing response against amyloid deposits include A.beta.15-21, A.beta. 16-22, A.beta.17-23, A.beta.18-24, A.beta.19-25, A.beta.015-22, A.beta.16-23, A.beta.17-24, A.beta.18-25, A.beta.15-23, A.beta.16-24, A.beta.17-25, A.beta.18-26, A.beta.15-24, A.beta.16-25, and A.beta.15-25. A.beta.16-23 is particularly preferred meaning s a fragment including residues 16-23 of A.beta. and lacking other residues of A.beta.. Also preferred are C-terminal fragments of A.beta.42 or 43 of 5-10 and preferably 7-10 contiguous amino acids. Analogous C-terminal fragments of A.beta.40, or 39 can also be used. These fragments can generate an antibody response that includes end-specific antibodies. Fragments preferably lack T-cell epitopes that would induce T-cells against A.beta.. Generally, T-cell epitopes are greater than 10 contiguous amino acids. Therefore, preferred fragments of A.beta. are of size 5-10 or preferably 7-10 contiguous amino acids; i.e., sufficient length to generate an antibody response without generating a T-cell response. Absence of T-cell epitopes is preferred because these epitopes are not needed for immunogenic activity of fragments, and may cause an undesired inflammatory response in a subset of patients.

[0265] Agents to induce antibodies to A.beta. that can be used in the methods of the invention also include (i) ACI-24 (AC Immune); (ii) Affitopes AD02 and AD02 (Affiris GmbH); (iii) Arctic Immunotherapeutic KLVFFAGDV (SEQ ID NO: 92) (BioArctic Neuroscience/Eisai); (iv) A.beta.1-15-K-K-A.beta.1-15 (Brigham & Women's Hospital); (v) .beta.-Vax.TM. and Recall-Vax.TM. (Intellect Neurosciences); (vi) K6-A.beta.1-30 (Intellect Neurosciences/NYU); (vii) V-950 (Merck); (viii) CAD106 (Novartis/Cytos); (ix) A.beta. DCtag.TM. nanoparticle adjuvant (Prana Biotechnology/PRIMABioMed); (x) PX106 (also 2A.beta.1-11-PADRE, from Pharmexa/Lundbeck); (xi) A.beta.4-10 conjugated to a T cell epitope (U. Toronto); and (xii) p3102 and p3075 (United Biomedical).

[0266] ACI-24 is an A.beta.1-15 liposome construct with A.beta.1-15-K-K-16C palmitic acid inserted into a liposomal bilayer. These compounds are described in US 2004/0242845, WO 05/081872, US 2007/0281006, and US 2006/0073158. Affitopes AD01 and AD02 are mimotopes from the N-terminus of A.beta., as described in WO 06/005707. The Arctic Immunotherapeutic is derived from A.beta.22 of E692G, as described in US 20020162129 and US 20070248606. A.beta.1-15-K-K-A.beta.1-15 represents two linked N-terminal A.beta. fragments, as described in WO 05/012330 and WO 02/0123553. .beta.-Vax.TM., Recall-Vax.TM. and K6-A.beta.1-30 are A.beta. fragments linked to a T cell epitope, as described in WO 01/42306. V-950 is an 8-mer A.beta. peptide linked to a multivalent linear peptide with at least one spacer and a multivalent branched multiple antigen peptide, as described in WO 06/121656. CAD 106 is a Q.beta. carrier (an RNA VLP) linked to an N-terminal A.beta. peptide, as described in WO 04/016282. The A.beta. DCtag.TM. nanoparticle adjuvant is described, e.g., in WO 02/00245. PX106 is a A.beta.1-11 peptide linked to a T cell epitope called a "pan DR epitope peptide (PADRE)," as described in U.S. Pat. No. 7,135,181. p3102 and p3075 are A.beta.1-14 peptides linked by a spacer to a T cell epitope (e.g., measles epitope), as described in US 20030068325 US 20040247612, U.S. Pat. No. 6,906,169, and WO 02/096350.

[0267] Fragments are usually natural A.beta. peptides but can include unnatural amino acids or modifications of N or C terminal amino acids at a one, two, five, ten or even all positions. For example, the natural aspartic acid residue at position 1 and/or 7 of A.beta. can be replaced with iso-aspartic acid. Examples of unnatural amino acids are D, alpha, alpha-disubstituted amino acids, N-alkyl amino acids, lactic acid, 4-hydroxyproline, .gamma.-carboxyglutamate, epsilon-N,N,N-trimethyllysine, epsilon-N-acetyllysine, O-phosphoserine, N-acetylserine, N-formylmethionine, 3-methylhistidine, 5-hydroxylysine, omega-N-methylarginine, .beta.-alanine, ornithine, norleucine, norvaline, hydroxproline, thyroxine, .gamma.-amino butyric acid, homoserine, citrulline, and isoaspartic acid. Some therapeutic agents of the invention are all-D peptides, e.g., all-D A.beta. or all-D A.beta. fragment, and all-D peptide analogs. Fragments can be screened for prophylactic or therapeutic efficacy in transgenic animal models in comparison with untreated or placebo controls.

[0268] Fragments are typically conjugated to carrier molecules, which provide a T-cell epitope, and thus promote an immune response against the fragment conjugated to the carrier. A single agent can be linked to a single carrier, multiple copies of an agent can be linked to multiple copies of a carrier, which are in turn linked to each other, multiple copies of an agent can be linked to a single copy of a carrier, or a single copy of an agent can be linked to multiple copies of a carrier, or different carriers. Suitable carriers include serum albumins, keyhole limpet hemocyanin, immunoglobulin molecules, thyroglobulin, ovalbumin, tetanus toxoid, or a toxoid from other pathogenic bacteria, such as diphtheria (e.g., CRM197), E. coli, cholera, or H. pylori, or an attenuated toxin derivative. T cell epitopes are also suitable carrier molecules. Some conjugates can be formed by linking agents of the invention to an immunostimulatory polymer molecule (e.g., tripalmitoyl-S-glycerine cysteine (Pam.sub.3Cys), mannan (a mannose polymer), or glucan (a .beta.1.fwdarw.2 polymer)), cytokines (e.g., IL-1, IL-1 alpha and .beta. peptides, IL-2, .gamma.-INF, IL-10, GM-CSF), and chemokines (e.g., MIP1-.alpha. and .beta., and RANTES). Immunogenic agents can also be linked to peptides that enhance transport across tissues, as described in O'Mahony, WO 97/17613 and WO 97/17614. Immunogens may be linked to the carries with or with out spacers amino acids (e.g., gly-gly).

[0269] Additional carriers include virus-like particles. Virus-like particles (VLPs), also called pseudovirions or virus-derived particles, represent subunit structures composed of multiple copies of a viral capsid and/or envelope protein capable of self assembly into VLPs of defined spherical symmetry in vivo. (Powilleit, et al., (2007) PLoS ONE 2(5):e415.) These particles have been found to be useful as antigen delivery systems. VLPs can be produced and readily purified in large quantities and due to their particulate nature and high molecular weights. VLPs induce an immune response without additional application of an adjuvant. (Ulrich et al., (1996) Intervirology 39:126-132.) Exemplary chimeric particles useful as VLP antigen delivery systems include those based on hepatitis B virus, human immunodeficiency virus (HIV), yeast retrotransposon Ty, yeast totivirus L-A, parvovirus, influenza virus, Norwalk virus, rotavirus, adeno-associated virus, bluetongue virus, hepatitis A virus, human papillomavirus, measles virus, polyoma virus and RNA phage virus, as well as those based on various retroviruses and lentiviruses. For review, see Lechner, et al. (2002) Intervirology 45:212-217.

[0270] The core protein of hepatitis B virus (HBcAg) is a common VLP used for carrying foreign antigens (see Koletzki et al., (1997) J Gen Vir 78:2049-2053). Briefly, HBcAg can be used as a core to construct VLPs that present extended foreign protein segments. The method employs a construct having a linker sequence between the a C-terminally truncated HBcAg and a foreign protein sequence that contains a stop codon. Truncated HBcAg/foreign protein chimera is expressed utilizing a read through mechanism based on the opal TGA-Trp mutation for expression in an E. coli suppressor strain. The method described by Koletzki et al. allows for incorporation of long foreign protein sequences into VLPs, allowing for a greater variety of antigens to be carried by the VLP.

[0271] The HIV virus Gag protein can be used as an antigen carrier system (see Griffiths et al., (1993) J. Virol. 67(6):3191-3198). Griffiths utilized the V3 loop of HIV, which is the principle neutralizing determinant of the HIV envelope. The Gag:V3 fusion proteins assembled in vivo into hybrid Gag particles, designated virus-derived particles (VDPs). The VDPs induce both humoral and cellular responses. As the V3 loop contains a CTL epitope, immunization with Gag:V3 induces a CTL response to the V3 protein portion of the VLP.

[0272] A hybrid HIV:Ty VLP can also be used (see Adams et al., (1987) Nature 329(3):68-70). The HIV:Ty VLP employs the p1 protein of the yeast transposon Ty. The first 381 amino acids of p1 are sufficient for VLP formation. The HIV:Ty fusion proteins are capable of assembling into VLPs in vivo, as well as inducing an immune response to the HIV antigen carried by the VLP. VLPs using the Ty p1 protein can also contain p1 fused to the whole of an alpha2-interferon, the product of the bovine papilloma virus E1 and E2 genes, and a portion of an influenza hemagglutinin. Each of these Ty fusions formed VLPs and were capable of inducing production of antisera to the non-Ty VLP component.

[0273] VLPs can also be designed from variants of the yeast totivirus L-A (see Powilleit et al. (2007) PLOS One 2(5):e415). The Pol gene of the L-A virus can be replaced with an appropriate antigen to induce a specific immune response, demonstrating that yeast VLPs are effective antigen carriers.

[0274] Recombinant, nonreplicative parvovirus-like particles can also be used as antigen carriers. (Sedlik, et al. (1997) PNAS 94:7503-7508.) These particles allow the carried antigens into the cytosol so they enter the class I-restricted immunological pathway, thus stimulating cytotoxic T-lymphocyte (CTL) mediated responses. Sedlik specifically used PPV:VLP, which contained the VP2 capsid protein of the parvovirus and residues 118-132 from the lymphocytic choriomeningitis virus (LCMV) was inserted into the VP2 capsid protein. The PPV:VLP containing LCMV was capable of inducing an immune response to LCMV and elicited immunological protection against lethal viral doses in pre-immunized mice.

[0275] VLPs can also comprise replication incompetent influenza that lack the influenza NS2 gene, the gene essential for viral replication. (Watanabe, et al. (1996) J Virol. 76(2):767-773.) These VLPs infect mammalian cells and allow expression of foreign proteins.

[0276] Norwalk virus (NV)-based VLPs can also be used as vehicles for immunogen delivery. (Ball, et al. (1999) Gastroenterology 117:40-48.) The NV genome has three open reading frames (ORFs 1-3). Recombinant baculovirus expression of ORFs 2 and 3 allows for spontaneous assembly of high yields of recombinant Norwalk virus (rNV) VLPs.

[0277] Some conjugates can be formed by linking agents of the invention to at least one T cell epitope. Some T cell epitopes are promiscuous whereas other T cell epitopes are universal. Promiscuous T cell epitopes are capable of enhancing the induction of T cell immunity in a wide variety of subjects displaying various HLA types. In contrast to promiscuous T cell epitopes, universal T cell epitopes are capable of enhancing the induction of T cell immunity in a large percentage, e.g., at least 75%, of subjects displaying various HLA molecules encoded by different HLA-DR alleles.

[0278] A large number of naturally occurring T-cell epitopes exist, such as, tetanus toxoid (e.g., the P2 and P30 epitopes), Hepatitis B surface antigen, pertussis, toxoid, measles virus F protein, Chlamydia trachomatis major outer membrane protein, diphtheria toxoid, Plasmodium falciparum circumsporozoite T, Plasmodium falciparum CS antigen, Schistosoma mansoni triose phosphate isomerase, Escherichia coli TraT, and Influenza virus hemagglutinin (HA). The immunogenic peptides of the invention can also be conjugated to the T-cell epitopes described in Sinigaglia F. et al., Nature, 336:778-780 (1988); Chicz R. M. et al., J. Exp. Med., 178:27-47 (1993); Hammer J. et al., Cell 74:197-203 (1993); Falk K. et al., Immunogenetics, 39:230-242 (1994); WO 98/23635; and, Southwood S. et al. J. Immunology, 160:3363-3373 (1998).

[0279] Carriers also include virus-like particles (see US 20040141984).

[0280] Fragments are often administered with pharmaceutically acceptable adjuvants. The adjuvant increases the titer of induced antibodies and/or the binding affinity of induced antibodies relative to the situation if the peptide were used alone. A variety of adjuvants can be used in combination with an immunogenic fragment of A.beta., to elicit an immune response. Preferred adjuvants augment the intrinsic response to an immunogen without causing conformational changes in the immunogen that affect the qualitative form of the response. Preferred adjuvants include aluminum hydroxide and aluminum phosphate, 3 De-O-acylated monophosphoryl lipid A (MPL.TM.) (see GB 2220211 (RIBI ImmunoChem Research Inc., Hamilton, Mont., now part of Corixa). Stimulon.TM. QS-21 is a triterpene glycoside or saponin isolated from the bark of the Quillaja Saponaria Molina tree found in South America (see Kensil et al., in Vaccine Design: The Subunit and Adjuvant Approach (eds. Powell & Newman, Plenum Press, NY, 1995); U.S. Pat. No. 5,057,540), (Aquila BioPharmaceuticals, Framingham, Mass.; now Antigenics, Inc., New York, N.Y.). Other adjuvants are oil in water emulsions (such as squalene or peanut oil), optionally in combination with immune stimulants, such as monophosphoryl lipid A (see Stoute et al., N. Engl. J. Med. 336, 86-91 (1997)), pluronic polymers, and killed mycobacteria. Another adjuvant is CpG (WO 98/40100). Adjuvants can be administered as a component of a therapeutic composition with an active agent or can be administered separately, before, concurrently with, or after administration of the therapeutic agent.

[0281] A preferred class of adjuvants is aluminum salts (alum), such as alum hydroxide, alum phosphate, alum sulfate. Such adjuvants can be used with or without other specific immunostimulating agents such as MPL or 3-DMP, QS-21, polymeric or monomeric amino acids such as polyglutamic acid or polylysine. Another class of adjuvants is oil-in-water emulsion formulations. Such adjuvants can be used with or without other specific immunostimulating agents such as muramyl peptides (e.g., N-acetylmuramyl-L-threonyl-D-isoglutamine (thr-MDP), N-acetyl-normuramyl-L-alanyl-D-isoglutamine (nor-MDP), N-acetylmuramyl-L-alanyl-D-isoglutaminyl-L-alanine-2-(1'-2'dipalmitoyl-sn- -glycero-3-hydroxyphosphoryloxy)-ethylamine (MTP-PE), N-acetylglucsaminyl-N-acetylmuramyl-L-A1-D-isoglu-L-Ala-dipalmitoxy propylamide (DTP-DPP) Theramide.TM.), or other bacterial cell wall components. Oil-in-water emulsions include (a) MF59 (WO 90/14837), containing 5% Squalene, 0.5% Tween 80, and 0.5% Span 85 (optionally containing various amounts of MTP-PE) formulated into submicron particles using a microfluidizer such as Model 110Y microfluidizer (Microfluidics, Newton Mass.), (b) SAP, containing 10% Squalene, 0.4% Tween 80, 5% pluronic-blocked polymer L 121, and thr-MDP, either microfluidized into a submicron emulsion or vortexed to generate a larger particle size emulsion, and (c) Ribi.TM. adjuvant system (RAS), (Ribi ImmunoChem, Hamilton, Mont.) containing 2% squalene, 0.2% Tween 80, and one or more bacterial cell wall components from the group consisting of monophosphorylipid A (MPL), trehalose dimycolate (TDM), and cell wall skeleton (CWS), preferably MPL+CWS (Detox.TM.).

[0282] Another class of preferred adjuvants is saponin adjuvants, such as Stimulon.TM. (QS-21, Aquila, Framingham, Mass.) or particles generated therefrom such as ISCOMs (immunostimulating complexes) and ISCOMATRIX. Other adjuvants include RC-529, GM-CSF and Complete Freund's Adjuvant (CFA) and Incomplete Freund's Adjuvant (IFA). Other adjuvants include cytokines, such as interleukins (e.g., IL-1 .alpha. and .beta. peptides, IL-2, IL-4, IL-6, IL-12, IL13, and IL-15), macrophage colony stimulating factor (M-CSF), granulocyte-macrophage colony stimulating factor (GM-CSF), tumor necrosis factor (TNF), chemokines, such as MIP1.alpha. and .beta. and RANTES. Another class of adjuvants is glycolipid analogues including N-glycosylamides, N-glycosylureas and N-glycosylcarbamates, each of which is substituted in the sugar residue by an amino acid, as immuno-modulators or adjuvants (see U.S. Pat. No. 4,855,283). Heat shock proteins, e.g., HSP70 and HSP90, may also be used as adjuvants.

[0283] An adjuvant can be administered with an immunogen as a single composition, or can be administered before, concurrent with or after administration of the immunogen. Immunogen and adjuvant can be packaged and supplied in the same vial or can be packaged in separate vials and mixed before use. Immunogen and adjuvant are typically packaged with a label indicating the intended therapeutic application. If immunogen and adjuvant are packaged separately, the packaging typically includes instructions for mixing before use. The choice of an adjuvant and/or carrier depends on the stability of the immunogenic formulation containing the adjuvant, the route of administration, the dosing schedule, the efficacy of the adjuvant for the species being vaccinated, and, in humans, a pharmaceutically acceptable adjuvant is one that has been approved or is approvable for human administration by pertinent regulatory bodies. For example, Complete Freund's adjuvant is not suitable for human administration. Alum, MPL and QS-21 are preferred. Optionally, two or more different adjuvants can be used simultaneously. Preferred combinations include alum with MPL, alum with QS-21, MPL with QS-21, MPL or RC-529 with GM-CSF, and alum, QS-21 and MPL together. Also, Incomplete Freund's adjuvant can be used (Chang et al., Advanced Drug Delivery Reviews 32, 173-186 (1998)), optionally in combination with any of alum, QS-21, and MPL and all combinations thereof.

V. Patients Amenable to Treatment

[0284] The present regimes are useful for treatment of any disease characterized by amyloid deposits of A.beta. in the brain. As well as Alzheimer's disease, such diseases include Down's syndrome, Parkinson's disease, mild-cognitive impairment, and vascular amyloid disease. Patients amenable to treatment include individuals at risk of disease but not showing symptoms, as well as patients presently showing symptoms. In the case of Alzheimer's disease, virtually anyone is at risk of suffering from Alzheimer's disease if he or she lives long enough. Therefore, the present methods can be administered prophylactically to the general population without the need for any assessment of the risk of the subject patient. The present methods can also be useful for individuals who have a known genetic risk of Alzheimer's disease. Such individuals include those having relatives who have experienced this disease, and those whose risk is determined by analysis of genetic or biochemical markers. Genetic markers of risk toward Alzheimer's disease include mutations in the APP gene, particularly mutations at position 717 and positions 670 and 671 referred to as the Hardy and Swedish mutations respectively (see Hardy, supra). Other markers of risk are mutations in the presenilin genes, PS1 and PS2, and ApoE4, family history of A.beta., hypercholesterolemia or atherosclerosis. Individuals presently suffering from Alzheimer's disease can be recognized from characteristic dementia, as well as the presence of risk factors described above. In addition, a number of diagnostic tests are available for identifying individuals who have AD. These include measurement of CSF tau and A.beta.42 levels. Elevated tau and decreased A.beta.42 levels signify the presence of A.beta.. Individuals suffering from Alzheimer's disease can also be diagnosed by ADRDA criteria as discussed in the Examples section.

[0285] In asymptomatic patients, treatment can begin at any age (e.g., 10, 20, 30). Usually, however, it is not necessary to begin treatment until a patient reaches 40, 50, 60 or 70 years of age. Treatment typically entails multiple dosages over a period of time. Treatment can be monitored by assaying antibody levels over time. If the response falls, a booster dosage is indicated. In the case of potential Down's syndrome patients, treatment can begin antenatally by administering therapeutic agent to the mother or shortly after birth.

[0286] Patients amenable to treatment include patients 50 to 87 years of age, patients suffering from mild to moderate Alzheimer's disease, patients having an MMSE score of 14-26, patients having a diagnosis of probable Alzheimer's disease based on Neurological and Communicative Disorders and Stroke-Alzheimer's disease Related Disorders (NINCDS-ADRDA) criteria, and/or patients having an Rosen Modified Hachinski Ischemic score less than or equal to 4. Patients with MRI an scan consistent with the diagnosis of Alzheimer's disease, i.e., that there are no other abnormalities present on the MRI that could be attributed to other diseases, e.g. stroke, traumatic brain injury, arachnoid cysts, tumors, etc are also amendable to treatment.

VI. Treatment Regimes

[0287] In prophylactic applications, agents or pharmaceutical compositions or medicaments containing the same are administered to a patient susceptible to, or otherwise at risk of, Alzheimer's disease in an amount sufficient to eliminate or reduce the risk, lessen the severity, or delay the outset of the disease, including biochemical, histologic and/or behavioral symptoms of the disease, its complications and intermediate pathological phenotypes presenting during development of the disease. In therapeutic applications, compositions or medicaments are administered to a patient suspected of, or already suffering from such a disease in an amount sufficient to cure, or at least partially arrest, the symptoms of the disease (biochemical, histologic and/or behavioral), including its complications and intermediate pathological phenotypes in development of the disease.

[0288] Effective doses of the compositions of the present invention, for the treatment of the above described conditions vary depending upon many different factors, including means of administration, target site, physiological state of the patient, whether the patient is human or an animal, other medications administered, and whether treatment is prophylactic or therapeutic.

[0289] Optionally, antibodies are administered to achieve a mean serum concentration of administered antibody of 0.1-60, 0.4-20, or 1-15 .mu.g/ml in a patient. These ranges bracket the demonstrated effective concentrations in mice and humans allowing some margin for error in measurement and individual patient variation. The serum concentration can be determined by actual measurement or predicted from standard pharmacokinetics (e.g., WinNonline Version 4.0.1 (Pharsight Corporation, Cary, USA)) based on the amount of antibody administered, frequency of administration, route of administration and antibody half-life.

[0290] The mean antibody concentration in the serum is optionally within a range of 1-10, 1-5 or 2-4 .mu.g/ml. It is also optional to maintain a maximum serum concentration of the antibody in the patient less than about 28 .mu.g antibody/ml serum for maximizing therapeutic benefit relative to the occurrence of possible side effects, particularly vascular edema. A preferred maximum serum concentration is within a range of about 4-28 .mu.g antibody/ml serum. The combination of maximum serum less than about 28 .mu.g antibody/mil serum and an mean serum concentration of the antibody in the patient is below about 7 .mu.g antibody/ml serum is particularly beneficial. Optionally, the mean concentration is within a range of about 2-7 .mu.g antibody/ml serum.

[0291] The concentration of A.beta. in plasma following antibody administration changes roughly in parallel with changes of antibody serum concentration. In other words, plasma concentration of A.beta. is highest after a dose of antibody and then declines as the concentration of antibody declines between doses. The dose and regime of antibody administration can be varied to obtain a desired level of A.beta. in plasma. In such methods, the mean plasma concentration of antibody can be at least 450 pg/ml or for example, within a range of 600-30000 pg/ml or 700-2000 pg/ml or 800-1000 pg/ml.

[0292] The preferred dosage ranges for antibodies are from about 0.01 to 5 mg/kg, and more usually 0.1 to 3 mg/kg or 0.15-2 mg/kg or 0.15-1.5 mg/kg, of the host body weight. Subjects can be administered such doses daily, on alternative days, weekly, biweekly, monthly, quarterly, or according to any other schedule determined by empirical analysis. An exemplary treatment entails administration in multiple dosages over a prolonged period, for example, of at least six months. Additional exemplary treatment regimes entail administration once per every two weeks or once a month or once every 3 to 6 months.

[0293] For intravenous administration, doses of 0.1 mg/kg to 2 mg/kg, and preferably 0.5 mg/kg or 1.5 mg/kg administered intravenously quarterly are suitable. Preferred doses of antibody for monthly intravenous administration occur in the range of 0.1-1.0 mg/kg antibody or preferably 0.5-1.0 mg/kg antibody.

[0294] For more frequent dosing, e.g., from weekly to monthly dosing, subcutaneous administration is preferred. Subcutaneous dosing is easier to administer and can reduce maximum serum concentrations relative to intravenous dosing. The doses used for subcutaneous dosing are usually in the range of 0.01 to 0.6 mg/kg or 0.01-0.35 mg/kg, preferably, 0.05-0.25 mg/kg. For weekly or biweekly dosing, the dose is preferably in the range of 0.015-0.2 mg/kg, or 0.05-0.15 mg/kg. For weekly dosing, the dose is preferably 0.05 to 0.07 mg/kg, e.g., about 0.06 mg/kg. For biweekly dosing, the dose is preferably 0.1 to 0.15 mg/kg. For monthly dosing, the dose is preferably 0.1 to 0.3 mg/kg or about 0.2 mg/kg. Monthly dosing includes dosing by the calendar month or lunar month (i.e., every four weeks). Here as elsewhere in the application, dosages expressed in mg/kg can be converted to absolute mass dosages by multiplying by the mass of a typical patient (e.g., 70 or 75 kg) typically rounding to a whole number. Other regimes are described by e.g., PCT/US2007/009499. The dosage and frequency can be varied within these guidelines based on the ApoE status of the patient as discussed above.

[0295] The amount of an agent for active administration varies from 1-500 .mu.g per patient and more usually from 5-100 .mu.g per injection for human administration. Exemplary dosages per injection are 3, 10, 30, or 90 .mu.g for each human injection. The mass of immunogen also depends on the mass ratio of immunogenic epitope within the immunogen to the mass of immunogen as a whole. Typically, 10.sup.-3 to 10.sup.-5 micromoles of immunogenic epitope are used for each immunization of immunogen. The timing of injections can vary significantly from once a day, to once a year, to once a decade. On any given day that a dosage of immunogen is given, the dosage is greater than 1 .mu.g/patient and usually greater than 10 .mu.g/patient if adjuvant is also administered, and greater than 10 .mu.g/patient and usually greater than 100 .mu.g/patient in the absence of adjuvant. A typical regimen consists of an immunization followed by booster injections at time intervals, such as 6 week intervals. Another regimen consists of an immunization followed by booster injections 1, 2 and 12 months later. Another regimen entails an injection every two months for life Alternatively, booster injections can be on an irregular basis as indicated by monitoring of immune response. The dosage and frequency can be varied such that antibodies induced by an active agent have mean serum concentrations within a range of 0.1-60, 0.4-20, or 1-15 or 2-7 .mu.g/ml as in passive administration. The dosage and frequency can be varied within these guidelines based on the ApoE status of the patient as discussed above.

VII. Exemplary Regimes Depending On Carrier Status

[0296] The invention provides methods of treating non-carrier patients having Alzheimer's disease (e.g., mild or moderate) in which an effective regime of an antibody that specifically binds to an N-terminal epitope of A.beta. is administered to such a patient. The antibody can for example bind to an epitope within residues 1-11, 1-7, 1-5, or 3-7 of A.beta.. Optionally, the antibody is bapineuzumab. The dosage of the antibody can be within a range of about 0.15 mg/kg to 2 mg/kg administered by intravenous infusion. Optionally, the dosage is about 0.5 mg/kg to about 1 mg/kg The dosage can be administered for example every 8-16 weeks, every 1-14 weeks or every 13 weeks.

[0297] The invention also provides methods of reducing cognitive decline in a non-carrier patient having been diagnosed with mild or moderate Alzheimer's disease. The method entails administering an effective regime of an antibody that specifically binds to an N-terminal epitope of A.beta. to such a patient.

Optionally, the dosage is about 0.5 mg/kg to about 1 mg/kg The dosage can be administered for example every 8-16 weeks, every 1-14 weeks or every 13 weeks. Cognitive decline can be measured by comparing the patient being treated with the cognitive decline in a population of control patients also of non-carrier status and having mild or moderate Alzheimer's disease (e.g., a control population in a clinical trial). Cognitive ability can be measured by scales such as ADAS-COG, NTB, MMSE or CDR-SB. The rate of change in such a scale (points over time) in a patient can be compared with the mean decline in a population of control patients as described above.

[0298] The invention also provides methods of reducing brain volume decline in a non-carrier patient having been diagnosed with mild or moderate Alzheimer's disease.

Optionally, the antibody is an antibody that binds to an epitope within an N-terminal region of A.beta.. Optionally, the antibody is AAB-003. Optionally, the patients are monitored, e.g., quarterly, by MRI for vasogenic edema. If vasogenic edema-develops the frequency or dose can be reduced or eliminated. Vasogenic edema can optionally be treated with a corticosteroid. After resolution of vasogenic edema, administration of treatment can be resumed. Optionally, the dose is increased over time.

[0301] The invention also provides methods of treating a patient diagnosed with probable Alzheimer's disease, irrespective of ApoE4 status. In such methods, an effective regime of an antibody that specifically binds to an N-terminal region of A.beta. is administered. The antibody has a constant region mutation that reduces binding to C1q and/or and Fc.gamma. receptor relative to an otherwise identical antibody without the mutation. Optionally, the antibody is an antibody that binds to an epitope within an N-terminal region of A.beta.. Optionally, the antibody is AAB-003. Optionally, the patients are monitored, e.g., quarterly, by MRI for vasogenic edema. If vasogenic edema develops the frequency or dose can be reduced or eliminated. Vasogenic edema can optionally be treated with a corticosteroid. After resolution of vasogenic edema, administration of treatment can be resumed. Optionally, the dose is increased over time after resolution of vasogenic edema.

[0302] The invention provides methods of treating an ApoE carrier patient with Alzheimer disease comprising subcutaneously administering to a patient having the disease an antibody that specifically binds to an N-terminal epitope of A.beta..

VIII. Pharmaceutical Compositions

[0304] Agents of the invention are often administered as pharmaceutical compositions comprising an active therapeutic agent, i.e., and a variety of other pharmaceutically acceptable components. See Remington's Pharmaceutical Science (15th ed., Mack Publishing Company, Easton, Pa. (1980)). The preferred form depends on the intended mode of administration and therapeutic application. The compositions can also include, depending on the formulation desired, pharmaceutically-acceptable, non-toxic carriers or diluents, which are defined as vehicles commonly used to formulate pharmaceutical compositions for animal or human administration. The diluent is selected so as not to affect the biological activity of the combination. Examples of such diluents are distilled water, physiological phosphate-buffered saline, Ringer's solutions, dextrose solution, and Hank's solution. In addition, the pharmaceutical composition or formulation may also include other carriers, adjuvants, or nontoxic, nontherapeutic, nonimmunogenic stabilizers and the like.

[0305] Pharmaceutical compositions can also include large, slowly metabolized macromolecules such as proteins, polysaccharides such as chitosan, polylactic acids, polyglycolic acids and copolymers (such as latex functionalized Sepharose.TM., agarose, cellulose, and the like), polymeric amino acids, amino acid copolymers, and lipid aggregates (such as oil droplets or liposomes). Additionally, these carriers can function as immunostimulating agents (i.e., adjuvants).

[0306] Agents are typically administered parenterally. Antibodies are usually administered intravenously or subcutaneously. Agents for inducing an active immune response are usually administered subcutaneously or intramuscularly. For parenteral administration, agents of the invention can be administered as injectable dosages of a solution or suspension of the substance in a physiologically acceptable diluent with a pharmaceutical carrier that can be a sterile liquid such as water oils, saline, glycerol, or ethanol. Additionally, auxiliary substances, such as wetting or emulsifying agents, surfactants, pH buffering substances and the like can be present in compositions. Other components of pharmaceutical compositions are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, and mineral oil. In general, glycols such as propylene glycol or polyethylene glycol are preferred liquid carriers, particularly for injectable solutions. Antibodies can be administered in the form of a depot injection or implant preparation, which can be formulated in such a manner as to permit a sustained release of the active ingredient.

[0307] Some preferred formulations are described in US 20060193850. A preferred formulation has a pH of about 5.5 to about 6.5, comprises i. at least one A.beta. antibody at a concentration of about 1 mg/ml to about 30 mg/ml; ii. mannitol at a concentration of about 4% w/v or NaCl at a concentration of about 150 mM; iii. about 5 mM to about 10 mM histidine or succinate; and iv. 10 mM methionine. Optionally, the formulation also includes polysorbate 80 at a concentration of about 0.001% w/v to about 0.01% w/v. Optionally, the formulation has a pH of about 6.0 to about 6.5 and comprises about 10 mg/ml A.beta. antibody, about 10 mM histidine and about 4% w/v mannitol and about 0.005% w/v polysorbate 80 Optionally, the formulation has a pH of about 6.0 to about 6.2 and comprises about 20 mg/ml A.beta. antibody, about 10 mM histidine, about 4% w/v mannitol and about 0.005% w/v polysorbate 80. Optionally, the formulation has a pH of about 6.0 to about 6.2 and comprises about 30 mg/ml A.beta. antibody, about 10 mM histidine, about 4% w/v mannitol and about 0.005% w/v polysorbate 80.

[0308] Typically, compositions are prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection can also be prepared. The preparation also can be emulsified or encapsulated in liposomes or micro particles such as polylactide, polyglycolide, or copolymer for enhanced adjuvant effect, as discussed above (see Langer, Science 249: 1527 (1990) and Hanes, Advanced Drug Delivery Reviews 28:97 (1997)). The agents of this invention can be administered in the form of a depot injection or implant preparation, which can be formulated in such a manner as to permit a sustained or pulsatile release of the active ingredient.

[0309] Additional formulations suitable for other modes of administration include oral, intranasal, and pulmonary formulations, suppositories, and transdermal applications. For suppositories, binders and carriers include, for example, polyalkylene glycols or triglycerides; such suppositories can be formed from mixtures containing the active ingredient in the range of 0.5% to 10%, preferably 1%-2%. Oral formulations include excipients, such as pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, and magnesium carbonate. These compositions take the form of solutions, suspensions, tablets, pills, capsules, sustained release formulations or powders and contain 10%-95% of active ingredient, preferably 25%-70%.

IX. Kits and Labels

[0310] The invention provides kits containing an antibody binding to an N-terminal epitope of A.beta.. The antibody is typically provided in lyophilized or solution form in a vial, optionally in a single-dose form. The antibody in the vial is typically sterile and manufactured under GMP conditions. The kits can also include diluents, syringes, needles, intravenous or subcutaneous drips and the like. The kits typically contain instructions (e.g., a package insert or label) for use. In some kits, the instructions specify whether the antibody is to be provided to ApoE4 carriers or non-carriers or can be provided to both. The instructions can also specify that the antibody is not to be provided to ApoE4 carriers. In some kits, the instructions can provide information or sources for ApoE testing.

[0311] In some kits, the instructions specify results that can be achieved by administering the antibody. The results can include an inhibition of cognitive decline. The instructions can also include a measure of cognitive decline in a control patient (typically a mean value from a population of such patients) for purposes of comparison. Cognitive decline can be measured, by for example, ADAS-COG, NTB, MMSE or CDR-SB Likewise, the instructions can refer to inhibition of decrease in brain volume or inhibition of ventricular volume. The instructions can also include a measure of decrease in brain volume or inhibition of ventricular volume in a control patient (typically a mean value from a population of such patients for purposes of comparison).

[0312] In some kits, the instructions specify potential side effects including vasogenic edema. The instructions can also specify a monitoring regime, such as performing MRI at quarterly, six monthly or annual intervals. The instructions can specify different monitoring regimes for ApoE4 non-carriers and carriers as discussed above. The instructions can also specify altered dosing schedules on occurrence and/or resolution of vasogenic edema and treatment measures for vasogenic edema, such as corticosteroids.

[0313] The kits can also include instructions for patients for whom treatment is contraindicated such as prior brain injury, CVA, brain tumor, multiple lacunes, venothrombotic disease, anticoagulation (heparin/coumadin) or atrial fibrillation. The kits can also provide instructions for route (e.g., subcutaneous), dosage amount or frequency of dosing.

X. Antibodies with Mutated IgG1 Constant Region

[0314] The invention provides a human IgG1 constant region, in which amino acids at positions 234, 235, and 237 (EU numbering) are each alanine, and isolated antibodies or fusion proteins containing such a constant region. Such antibodies include human antibodies, humanized antibodies and chimeric antibodies as described above. Examples of such antibodies include antibodies to A.beta., antibodies to the Lewis Y antigen and the 5T4 tumor antigen, such as described in the Examples. Fusion proteins include the extracellular domains of receptors (e.g., TNF-alpha receptor) linked to a constant region. Methods for fusing or conjugating polypeptides to the constant regions of antibodies are described by, e.g., U.S. Pat. Nos. 5,336,603, 5,622,929, 5,359,046, 5,349,053, 5,447,851, 5,723,125, 5,783,181, 5,908,626, 5,844,095, 5,112,946; EP 0 307 434; EP 0 367 166; EP 0 394 827).

[0315] Antibodies or fusion proteins incorporating these mutations can offer advantages of the IgG1 isotype including pharmacokinetics and ease of manufacture, but also have reduced or eliminated effector function relative to an otherwise identical antibody lacking these mutations. Effector function is typically impaired in binding to one or more Fc gamma receptors, binding to C1Q, antibody-dependent cellular cytotoxicity and/or antibody-dependent complement activity. In some antibodies, all of these activities are reduced or eliminated. An activity is considered eliminated if there is no detectable difference beyond experimental error in that activity between an antibody having the above three mutations and an otherwise identical control antibody without the mutations.

[0316] Typically, a mutated constant region includes CH1, hinge, CH2 and CH3 domains. However, the CH1 domain is sometimes replaced particularly in fusion proteins with a synthetic linker. Some constant regions contain a full-length IgG1 constant region with the possible exception of a C-terminal lysine residue. Exemplary sequences of a mutated constant region are provided by SEQ ID NOS: 62 and 63. These sequences differ in the 62 contains a C-terminal lysine not present in 63.

[0317] The sequences 62 and 63 represent the G1mz allotype of human IgG1. Other examples of allotypes have been provided above. Allotypes are natural polymorphic variations in the human IgG1 constant region that differ between different individuals at the polymorphic position. The G1mz allotype has Glu at position 356 and Met at position 358.

[0318] Other allotypic variants of SEQ ID NOS. 62 and 63 are included. Also included are human IgG1 constant regions having alanine residues at positions 234, 235 and 237 any permutation of residues occupying polymorphic positions in natural allotypes.

[0319] Mutated IgG1 constant regions having alanine at positions 234, 235 and 237 can have additional mutations present relative to a natural human IgG1 constant region. As an example in which additional mutations can be present, alanine mutations at positions 234, 235 and 237 can be combined with mutations at positions 428 and/or 250 as described in U.S. Pat. No. 7,365,168. Mutations at positions 428 and 250 can result in increased half life. Additional mutations that can be combined with mutations at positions 234, 235 and 237 have been described in Section IV A in connection with antibodies that bind A.beta.. Some such constant regions have no additional mutations present. Some such constant regions have no additional mutations present in and around regions of the IgG1 constant region affecting Fc gamma receptor and/or complement binding (e.g., residues 230-240 and 325-325 by EU numbering). The omission of a C-terminal lysine residue by intracellular processing is not considered to be a mutation. Likewise, naturally occurring amino acids occupying polymorphic sites differing between allotypes are considered natural rather than mutant amino acids.

XI. Experimental Models, Assays and Diagnostics

A. Animal Models

[0320] Such models include, for example, mice bearing a 717 (APP770 numbering) mutation of APP described by Games et al., supra, and mice bearing a 670/671 (APP770 numbering) Swedish mutation of APP such as described by McConlogue et al., U.S. Pat. No. 5,612,486 and Hsiao et al., Science, 274, 99 (1996); Staufenbiel et al., Proc. Natl. Acad. Sci. USA, 94:13287-13292 (1997); Sturchler-Pierrat et al., Proc. Natl. Acad. Sci. USA, 94:13287-13292 (1997); Borchelt et al., Neuron, 19:939-945 (1997)); Richards et al., J. Neurosci. 23:8989-9003, 2003; Cheng, Nat. Med. 10(11): 1190-2, 2004 Hwang et al., Exp Neurol. 2004 Mar. Mutations of APP suitable for inclusion in transgenic animals include conversion of the wild-type Val717 (APP770 numbering) codon to a codon for Ile, Phe, Gly, Tyr, Leu, Ala, Pro, Trp, Met, Ser, Thr, Asn, or Gln. A preferred substitution for Val717 is Phe. Another suitable mutation is the arctic mutation E693G (APP 770 numbering). The PSAPP mouse, which has both amyloid precursor protein and presenilin transgenes, is described by Takeuchi et al., American Journal of Pathology. 2000; 157:331-339. A triple transgenic mouse having amyloid precursor protein, presenilin and tau transgenes is described by LaFerla, (2003), Neuron 39, 409-421. Another useful transgenic mouse has both APP and TGF-.beta. transgenes. Protein encoding sequences in transgenes are in operable linkage with one or more suitable regulatory elements for neural expression. Such elements include the PDGF, prion protein and Thy-1 promoters. Another useful transgenic mouse has an APP transgene with both a Swedish and 717 mutation. Another useful transgenic mouse has an APP transgene with an arctic mutation (E693G).

B. Assays to Detect Amyloid Related Pathologies

[0321] Contextual fear conditioning assays. Contextual fear conditioning (CFC) is a common form of learning that is exceptionally reliable and rapidly acquired in most animals, for example, mammals. Test animals learn to fear a previously neutral stimulus and/or environment because of its association with an aversive experience. (see, e.g., Fanselow, Anim. Learn. Behav. 18:264-270 (1990); Wehner et al., Nature Genet. 17:331-334. (1997); Caldarone et al., Nature Genet. 17:335-337 (1997)).

[0322] Contextual fear conditioning is especially useful for determining cognitive function or dysfunction, e.g., as a result of disease or a disorder, such as a neurodegenerative disease or disorder, an A.beta.-related disease or disorder, an amyloidogenic disease or disorder, the presence of an unfavorable genetic alteration effecting cognitive function (e.g., genetic mutation, gene disruption, or undesired genotype), and/or the efficacy of an agent, e.g., an A.beta. conjugate agent, on cognitive ability. Accordingly, the CFC assay provides a method for independently testing and/or validating the therapeutic effect of agents for preventing or treating a cognitive disease or disorder, and in particular, a disease or disorder affecting one or more regions of the brains, e.g., the hippocampus, subiculum, cingulated cortex, prefrontal cortex, perirhinal cortex, sensory cortex, and medial temporal lobe (see US 2008145373).

C. Phagocytosis Assays to Determine Antibody Effector Function

[0323] Antibodies can be screened for clearing an amyloid deposit in an ex vivo assay. A tissue sample from a brain of a patient with Alzheimer's disease or an animal model having characteristic Alzheimer's pathology is contacted with phagocytic cells bearing an Fc.gamma. receptor, such as microglial cells, and the antibody under test in a medium in vitro. The phagocytic cells can be a primary culture or a cell line, such as BV-2, C8-B4, or THP-1. A series of measurements is made of the amount of amyloid deposit in the reaction mixture, starting from a baseline value before the reaction has proceeded, and one or more test values during the reaction. The antigen can be detected by staining, for example, with a fluorescently labelled antibody to A.beta. or other component of amyloid plaques. A reduction relative to baseline during the reaction of the amyloid deposits indicates that the antibody under test has clearing activity.

[0324] Generally, isotype controls are added to ensure that the appropriate Fc-Fc.gamma. receptor interaction is being observed. Additional controls include use of non-specific antibodies, and/antibodies with a known affinity for the F.gamma.c receptors on the phagocytic cells. Such assays can be carried out with human or non-human tissues and phagocytic cells, and human, non-human, or humanized antibodies.

[0325] A variation on the ex vivo phagocytosis assay eliminates the need for an A.beta.-containing tissue, although still allowing detection of the interaction between a particular antibody and Fc.gamma. receptors. In this case, the assay relies on a solid matrix which is coated with antibody. The solid matrix is generally in a form that can be engulfed by a phagocytic cell, e.g., a bead or particle on the order of nanometers to several microns in size. The solid matrix can be conjugated to a detectable moiety, e.g., a fluorophore, so that the particle can be traced. Kits and materials for phagocytosis assays of this sort are commercially available, e.g., from Beckman Coulter (Fullerton, Calif.) and Molecular Probes (Eugene, Oreg.). An example of such an assay is provided in the Examples section.

D. Complement Binding Assays

[0326] Antibody effector function can also be determined by detecting the ability of an antibody to interact with complement, in particular, the C1q polypeptide (see, e.g., Mansouri et al. (1999) Infect. Immun. 67:1461). In the case of A.beta.-specific antibody, a solid matrix (e.g., a multiwell plate) can be coated with A.beta., and exposed to antibody, and, in turn, exposed to labelled C1q. Alternatively, C1q can be attached to the matrix, and labelled antibody added. Alternatively, the antibody can be attached to the matrix and exposed to C1q, followed by detection of C1q. Such in vitro binding assays are common in the art and are amenable to modification and optimization as necessary.

E. Diagnostic Methods

[0327] Cognitive function assessment tools. A number of tools exist to quantify the cognition and mental function of dementia patients. These include the NTB, DAD, ADAS, MMSE, CDR-SOB, NINCDS-ADRDA criteria, and the RMHI (Rosen Modified Hachinski Ischemic) score. These tools are generally known in the art.

[0328] The NTB (Neuropsychological Test Battery) is composed of nine well-accepted tests of memory and executive function. The test battery is acceptable in the most recent EMEA guidance. Patients are generally assessed in the following memory tests periodically: Weschsler Memory Scale Visual Paired Associates; Weschsler Memory Scale Verbal Paired Associates; and Rey Auditory Verbal Learning Test. The Executive function tests include: Wechsler Memory Scale Digit Span; Controlled Word Association Test; and Category Naming Test. This test is sensitive to change in mild A.beta. patients and clinical effects of amyloid lowering agents.

[0329] The DAD (Disability Assessment for Dementia) test was developed and validated to measure the functional disability of patients with Alzheimer's disease (Gelinas et al. (1999) Am J Occup Ther 53:471-81.) Caregivers answer questions about the patients' ability to perform both instrumental and basic activities of daily living that had been attempted in the preceding two weeks. The proportion of DAD activities successfully completed out of those attempted is then determined and reported as a percentage.

[0330] The ADAS-Cog refers to the cognitive portion of the Alzheimer's Disease Assessment Scale (see Rosen, et al. (1984) Am J Psychiatry 141:1356-64.) The test consists of eleven tasks that measure disturbances in memory, language, praxis, attention and other cognitive abilities.

[0331] The NINCDS-ADRDA (Neurological and Communicative Disorders and Stroke-Alzheimer's disease Related Disorders Assessment) measures eight criteria affected in Alzheimer's: memory, language, perceptual skills, attention, constructive abilities, orientation, problem solving, and functional abilities (McKhann et al. (1984) Neurology 34: 939-44)

[0332] The MMSE (Mini Mental State Exam), CDR-SOB (Clinical Dementia Rating--Sum of Boxes, and RMHI (Rosen Modified Hachinki Ischemic) score are also known in the art (see, e.g., Folstein et al. (1975) J Psych Res 12: 189-198; Morris (1993) Neurology 43: 2412-2414; and Rosen et al. (1980) Ann Neurol. 17:486-488).

[0333] Biomarkers. Biomarkers for Alzheimer's symptomology in humans can be measured using MRI volumetrics, blood and CSF protein levels, and PET (positron emission topography). For example, biomarkers to support antibody-A.beta. engagement include A.beta.40 and A.beta.42 in the CSF and plasma, and amyloid plaque imaging, e.g., by PET. Biomarkers pointing to disease modification include brain morphology (MRI), CSF tau and phosphotau levels, and again, amyloid plaque imaging.

XII. Examples

Example 1

Phase 1 Trial

[0334] 111 patients with a diagnosis of probable Alzheimer's disease (mild to moderate) were administered the humanized antibody bapineuzumab at doses ranging from 0.15 to 2.0 mg/kg in a multiple ascending dose study (MAD). Antibody was administered by intravenous infusion every thirteen weeks until the dosing regime is complete. Patients were also classified for ApoE4 status. Table 2 shows that eleven patients in the study experienced vasogenic edema detected by MRI. Table 2 also shows symptoms experienced in some of these patients; in other patients the vasogenic edema was asymptomatic. Table 3 shows the risk of vasogenic edema stratified by genotype irrespective of dose. The risk is only 2% in patients lacking an E4 allele but is 35% in patients with two E4 alleles. Table 4 shows the risk of vasogenic edema in only the highest dose group (2 mg/kg). The risk of vasogenic edema for patients with two E4 alleles is 60% and that for patients with one allele is 35%.

[0335] Table 5 shows the risk of vasogenic edema at different dosages. The risk of vasogenic edema is very low for all genotypes for doses between 0.15-0.5 mg/ml but starts to become significant for patients with two E4 alleles at a dose of 1 mg/kg and for patients with one E4 allele at 2 mg/kg. These data indicate that the risk of vasogenic edema is dependent on both ApoE genotype and dose and patients.

Example 2

Phase 2 Trial

[0336] A randomized double-blind placebo-controlled multiple ascending dose study was conducted on a population of 234 patients randomized from an initial population of 317 screened patients. Patients were assessed for ApoE4 carrier status, but carriers (homozygous and heterozygous) and non-carriers received the same treatment. Inclusion criteria were: probable A.beta. diagnosis; aged 50-85 years; MMSE score 16-26; Rosen Modified Hachinski Ischemic score .ltoreq.4; Living at home or in a community dwelling with a capable caregiver; MRI consistent with diagnosis of A.beta.; MRI scan of sufficient quality for volumetric analysis; stable doses of medication for treatment of non-excluded conditions; stable doses of AchEIs and/or memantine for 120 days prior to screen. The main exclusion criteria were: current manifestation of a major psychiatric disorder (e.g., major depressive disorder); current systemic illness likely to result in deterioration of the patient's condition; history or evidence of a clinically important auto-immune disease or disorder of the immune system; history of any of the following: clinically evident stroke, clinically important carotid or vertebro-basilar stenosis/plaque, seizures, cancer within the last 5 years, alcohol/drug dependence within last 2 years, myocardial infarction within the last 2 years, a significant neurologic disease (other than A.beta.) that might affect cognition. Kits of the invention and their accompanying labels or package inserts can provide exclusions for patients meeting any of the above exclusion criteria and any subcombinations thereof.

[0337] Four dose levels were employed (0.15, 0.5, 1.0 and 2.0 mg/kg) together with a placebo. 124 patients received bapineuzumab and 110 received a placebo. Of those patients, 122 and 107, respectively, were analyzed for efficacy. Bapineuzumab was supplied as a sterile aqueous solution in 5 ml vials containing: 100 mg of bapineuzumab (20 mg/mL), 10 mM histidine, 10 mM methionine, 4% mannitol, 0.005% polysorbate-80 (vegetable-derived), pH of 6.0. The placebo was supplied in matching vials containing the same constituents except for bapineuzumab. The study medication was diluted in normal saline and administered as a 100 ml intravenous (IV) infusion over .about.1 hour

[0338] The treatment period was for 18 months with 6 intravenous infusions at 13 week intervals. Safety follow-up visits, including MRI scans occurred 6 weeks following each dose. Following the treatment period patients were either monitored with a 1 year safety follow up for continued treatment in open label extension. The primary objective of the trial was to evaluate the safety and tolerability of bapineuzumab in patients with mild to moderate Alzheimer's disease. The primary endpoints for the study were (Alzheimer Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), Disability Assessment Scale for Dementia (DAD) together with safety and tolerability). The ADAS-Cog 12 contains an additional test involving delayed recall of a ten item word list relative to the ADAS-Cog 11. The secondary objective of the study was to evaluate the efficacy of bapineuzumab in patients with mild to moderate Alzhiemer's disease. Other end points were neuropsychological test battery (NTB), neuropsychiatric inventory (NPI), clinical dementia rating sum of boxes (CDR-SB), MRI brain volumetrics, and CSF measures.

[0339] A summary of the total population, the populations broken down by dosage group and populations broken down by carrier status is provided is the following tables.

[0340] Comparison of the various dosage cohorts with placebo using a linear model of cognitive decline on ADAS-COG and DAD scales did not achieve statistical significance for any of the dosage cohorts or the combined dosage cohorts population.

[0341] The data were reanalyzed using a statistical model not assuming linear decline (a) based on all of the patients in whom efficacy was determined and (b) based only on patients who had received all six dosages ("completers") and not including patients who had dropped out for various reasons. The non-linear model is believed to be more accurate because the cognitive abilities do not necessarily decline linearly with time.

[0342] The results using the non-linear decline model for all of the patients in whom efficacy was determined (ApoE4 carriers and non-carriers combined) are shown in FIG. 1. MITT (modified intent to treat) analysis was done using the repeated measures model without assumption of linearity. Bars above the X-axis represent a favorable result (i.e., inhibited decline) relative to placebo. Although statistical significance was not obtained, a trend was observed for the combined dosage cohorts using the ADAS-cog and NTB scales (0.1.gtoreq.p.gtoreq.0.05).

[0343] The results for the completer populations (ApoE4 carriers and non-carriers combined) are shown in FIG. 2. Completers were defined as patients who received all 6 infusions and an efficacy assessment at week 78. Bars above the axis indicate improvement relative to placebo. Statistical significance was obtained for the combined dosage cohorts for ADAS-cog and DAD measurements and a positive trend (0.1.gtoreq.p.gtoreq.0.05) was found for NTB measurement.

[0344] Separate analyses were performed for ApoE4 carriers and non-carriers using the non-linear model and (a) all treated patients in whom efficacy was determined and (b) completers.

[0345] FIG. 3 shows the results for all ApoE4 carrier patients in which efficacy was measured. Statistical significance was not found for any of the cognitive scales. Again, MITT analysis used repeated measures model without assumption of linearity. FIG. 4 shows the analysis for ApoE4 carrier completers, as defined above. Again, statistical significance was not found by any of the scales (ADAS-cog, DAD, NTB, and CDR-SB). However, favorable directional changes (bars above the axis) were found particularly for the ADAS-cog and DAD measurements.

[0346] FIGS. 5 and 6 show the results for all ApoE4 non-carrier patients in whom efficacy was measured. Statistical significance was obtained for ADAS-cog, NTB, CDR-SB and MMSE measurements for the combined dosage cohorts. Bars above the axis indicate improvement relative to placebo. FIG. 9 shows time course analysis of these parameters (ADAS-cog, upper left, DAD, upper right, NTB, lower left, CDR-SB, lower right). The decline in cognitive performance for treated patients was less than that of placebo at all time points on the ADAS-cog, NTB and CDR-SB scales. FIGS. 7 and 8 show the analysis for ApoE4 non-carrier completers, as defined above. Statistical significance was again obtained for ADAS-cog, NTB, CDR-SB and MMSE measurements. Again, bars above the axis indicate improvement relative to placebo.

[0347] MRI was performed up to seven times per patient during the study six weeks after each infusion. Changes in the brain were assessed by brain volume, ventricular volume, brain boundary shift integral and ventricular boundary shift integral. The boundary shift integral (BSI) as a measure of cerebral volume changes derived from registered repeat three-dimensional magnetic resonance scans. The BSI determines the total volume through which the boundaries of a given cerebral structure have moved and, hence, the volume change, directly from voxel intensities. The ventricular shift integral is a similar measurement of ventricular space changes. Both of these parameters increase as Alzheimer's disease progresses. Thus, inhibition of the increase in these parameters relative to placebo shows a positive (i.e., desired) effect of treatment.

[0348] In the total treated population (carriers and non-carriers) no significant differences were found for changes in brain volume measured by brain boundary shift integral or ventricular volume measured by ventricular boundary shift integral over 78 weeks compared with the placebo population.

[0349] In the treated non-ApoE4 carrier population brain volume decline was significantly lower than the non-ApoE4 placebo population (mean -10.7 cc; 95% CI: -18.0 to -3.4; p=0.004). The increase in ventricular volume compared to placebo was also reduced but the change did not reach statistical significance. There was no significant change in brain volume compared with the ApoE4 placebo population. However, the ventricular volume increased significantly compared to placebo (mean 2.5 cc; 95% CI: 0.1 to 5. 1; p=0.037).

[0350] The changes of BBSI in the total population, ApoE4 carrier population and ApoE4 non-carrier population are shown in FIGS. 10-12. FIG. 12 (ApoE4 non-carriers) shows a statistically significant separation between the lines for treated patients and placebo. The change in brain volume was reduced in the treated population relative to placebo at all measured time points. FIG. 10 (combined ApoE4 carriers and non-carriers) shows separation of the lines for treated and placebo patients but the results did not reach statistical significance. FIG. 11 (ApoE4 carriers) shows the lines for treated and placebo patients are virtually superimposed. Analysis used repeated measures model with time as categorical, adjusting for APOE4 carrier status. Baseline was whole brain volume and MMSE stratum.

[0351] A trend was observed for reduction in CSF phospho-tau in the bapineuzumab treated patient population relative to the placebo treated population at 52 weeks into the trials (FIG. 13). Phospho-tau is a biomarker associated with Alzheimer's disease. No significant differences were found between CSF levels of tau and A.beta.42 between all treated patients and controls. The figure is based on ANCOVA analysis, adjusted for baseline value. One outlier was excluded in the 0.15 mg/kg placebo dose cohort.

[0352] Treatment was generally safe and well tolerated. Vasogenic edema (VE) occurred only in bapineuzumab treated patients. VE occurred with greater frequency in ApoE4 carriers (10) than non-carriers (2) and at greater frequency with increasing dose, there being 8, 3, 0 and 1 episodes at doses of 2.0, 1.0, 0.5 and 0.15 mg/kg respectively. All VE episodes occurred after the first or second dose. Most episodes of VE were detected only by MRI and had no detected clinical symptoms. The VE episodes resolved over weeks to months. In one patient, the VE was treated with steroids. Excluding VE, and excluding the 0.15 mg/kg cohort (which contained patients with more advanced disease than other cohorts), serious adverse events were similar between treated and placebo groups. Adverse events were generally mild to moderate, transient, considered unrelated to study drug, occurred in relatively small proportion of patients and did not appear to be dose-related.

[0353] Serum concentration of bapineuzumab and plasma concentration of A.beta. were measured in treated patients over time for the different dosage cohorts as shown in FIG. 14. The Cmax for serum bapineuzumab ranged from about 3.5-50 .mu.g/ml in the different dosage cohorts from 0.15 mg/kg to 2.0 mg/kg. The profile of mean plasma concentration of A.beta. mirrored that of mean serum bapineuzumab with the concentration of plasma A.beta. rising on dosing with bapineuzumab and declining as the concentration of bapineuzumab declined. The concentration of plasma A.beta. ranged from about 500-3000 pg/ml. The variation of plasma concentration of A.beta. between different dosage cohorts showed less variation than the variation between doses. For example, increasing the dose from 0.15 mg/kg to 2 mg/kg increases plasma A.beta. by about a factor of 2.

[0354] The PK parameters after the first infusion of bapineuzumab are summarized in Table 9 below.

Conclusions

[0355] 1. The trial provides evidence that ApoE4 carriers and non-carriers react differently to immunotherapy.

[0356] 2. The trial provides evidence that vasogenic edema occurs more frequently in ApoE4 carriers and at higher dosages.

[0357] 3. The trial provides statistically significant evidence of efficacy in non-ApoE4 carriers and in patients receiving at least 6 doses of bapineuzumab (ApoE4 carriers and non-carriers).

[0358] 4. The trial provides evidence of trends or favorable directional changes in a total population (ApoE4 carriers and non-carriers) and ApoE4-carrier population by some measures. Statistical significance might be shown with larger populations. Alternative treatment regimes in these patients such as discussed above are likely to improve efficacy as discussed above.

[0359] 5. The trial provides evidence that the treatment is generally safe and well tolerated.

Example 3

Clinical Study of Subcutaneous Administration of Bapineuzumab in Alzheimer's Patients

[0360] Subcutaneous injections are generally easier to administer, which can be a consideration for patients with impaired mental function and coordination, or caregivers administering to an uncooperative patient. It is also easier to do at home, which is less upsetting to the patient, as well as less expensive. Finally, subcutaneous administration usually results in a lower peak concentration of the composition (Cmax) in the patient's system than intravenous. The reduced peak can reduce the likelihood of vasogenic edema.

[0361] For these reasons, a clinical study was designed for subcutaneous administration of bapineuzumab. The primary endpoints for the initial study are safety and bioavailability. Once these are established for subcutaneous administration, the cognitive tests described above will be administered to determine efficacy.

[0362] Under the initial regime, bapineuzumab is administered subcutaneously to patients every 13 weeks for 24 months, for a total of 9 doses. All patients receive a dose of 0.5 mg/kg. Patients are screened and periodically monitored as described in the above examples, e.g., for blood levels of the antibody, heart function, and vasogenic edema.

Example 4

Design of Specific Mouse and Human Antibodies

[0363] Variants of humanized and mouse 3D6 antibodies differing in isotype and or constant region mutations were constructed to test effects of reducing effector function on amyloid deposit clearing, cognitive function and microhemorrhaging. Mice treated with antibodies to A.beta. proteins often exhibit signs of microhemorrhage in cerebral vessels, which is one factor that my be related to the vasogenic edema observed in human patients undergoing similar treatment.

[0364] An alignment of the CH2 domains of human IgG1, IgG2, and IgG4 with mouse IgG1 and IgG2a are shown in FIG. 15. The alignment highlights the residues responsible for FcR and C1q binding. The C1q binding motif is conserved across species and isotypes. The FcR binding motif is conserved in human IgG1, IgG4, and murine IgG2a.

[0365] The following table discloses the particular modifications made to the CH2 region of the heavy chain. The amino acid numbering is by the EU system. The format is wildtype residue, position, mutant residue.

[0366] The epitope-binding regions of 3D6 derivative antibodies are the same, and the kinetics of A.beta. binding are comparable. Table 11 discloses the kinetics of the Fc receptor binding to the 3D6 derivative antibodies listed in Table 10. These values were generated as follows.

[0367] For the humanized 3D6 derivative antibodies, the following assay conditions were used. A Biacore 3000 and CM5 chip coated with penta-His (SEQ ID NO: 93) antibody (Qiagen, Cat # 34660) was used in combination with His-tagged domains of human Fc.gamma.RI, Fc.gamma.RII, and Fc.gamma.RII (R&D Systems, Cat # 1257-Fc, 1330-CD, 1597-Fc). Each receptor was separately captured in one flow cell of the sensor chip by the penta-His (SEQ ID NO: 93) antibody. A solution of the antibody to be tested was injected to enable measurements of association and dissociation rates to the captured receptor. After measurements were completed, the receptors and experimental antibodies were removed by injection of buffer at pH2.5. The flow cell was then ready for the next cycle. Each cycle was carried out in duplicate, and the same conditions (e.g., concentrations, flow rates, and timing) were used for each sample.

[0368] As indicated by the values in Table 11, bapineuzumab (unmodified Fc region) bound to all of the human Fc.gamma.R receptors with relatively high affinity. KD for Fc.gamma.RI was in the nm range, while KD for Fc.gamma.RII and III were in the .mu.m range. For the latter two, the sensorgrams showed typical fast-on, fast-off kinetics. IgG4 isotype had similar binding to Fc.gamma.RI, but did not bind Fc.gamma.RIII, as expected. The two IgG1 derivatives, Hu 3D6 2 m and 3 m, did not show detectable binding to either Fc.gamma.RI or Fc.gamma.RIII.

[0369] For the mouse 3D6 derivative antibodies, similar methods were used to determine binding to mouse Fc.gamma.RI, II, and III. Fc.gamma.RI and III are activating receptors, while Fc.gamma.RII is generally considered to be inhibitory. The antibodies tested were 3D6 IgG2a, 3D6 IgG1, and the IgG1 mutants, 3D61 m, 3 m and 4 m. Results are expressed as a relative percentage of 3D6 IgG2a binding. As shown in Table 11, 3D6 IgG2a was the only antibody with detectable Fc.gamma.RI binding ability. 3D6 IgG1 and the 3D6 3 m IgG1 had similar Fc.gamma.RII and III binding profiles.

TABLE-US-00084 TABLE 11 Fc Receptor Binding Ability of 3D6 Antibodies Relative Binding Capability* (%) Human 3D6 Derivative Human Fc.gamma.RI** Human Fc.gamma.RII** Fc.gamma.RIII** Bapineuzumab Control 100 100 100 Humanized 3D6 1m 85-95 40-50 0 Humanized 3D6 2m 0 40-50 0 Humanized 3D6 3m 0 8-12 0 AAB-003 Mouse Mouse Fc.gamma.RI** Mouse Fc.gamma.RII** Fc.gamma.RIII** 3D6 Control IgG2a 100*** 100 100 3D6 Control IgG1 0 180 70 3D6 1m IgG1 0 15 10 3D6 3m IgG1 0 180 70 3D6 4m IgG1 0 25 15 *Defined as the amount of binding in (RU) relative to that of IgG2a control at the steady state **The mFc.gamma.RI and mFc.gamma.RIII are activating receptors, mFc.gamma.RII is an inhibitory receptor. Another potent activating receptor, mFc.gamma.RIV, is not commercially available. ***A steady-state binding was not reached. Kinetic fitting led to an estimate of K.sub.D in the nanomolar range.

[0370] The above results show that that the Hu 3D6 3 m (AAB-003) antibody has the most reduced Fc gamma receptor binding of the three tested. Of those tested, the 3D6 .mu.m IgG1 mouse mutant antibody was the most similar to AAB-003, in that its Fc.gamma.R binding was reduced to near 10% of normal.

Mouse Studies of 3D6 Derivative Antibodies

Study Design

[0371] One-year old PDAPP mice were exposed to a 6 month treatment paradigm with control or the 3D6 derivative antibodies described in Table 10. The negative control was a mouse IgG2a antibody to an irrelevant, non-amyloid epitope. The mice were injected IP with 3 mg/kg of the indicated antibody each week.

[0372] Serum antibody concentrations were tested over the course of the study by ELISA. Levels were comparable in all groups. After six months, the mice were sacrificed and perfused. Brain sections and tissues were prepared according to known methods (Johnson-Wood et al. (1997) Proc. Natl. Acad. Sci., USA 94:1550-55).

[0373] Amyloid burden was measured in the cortex and hippocampus of transgenic mice. Results in Table 12A and 12B are indicated as percentage reduction of area with amyloid (p values indicate significant difference compared to IgG2a control antibody).

TABLE-US-00085 TABLE 12A Cortical Amyloid Burden (% reduction) Control 3D6 Control 3D6 Control 3D6 1m IgG1 3D6 3m IgG1 IgG2a IgG2a IgG1 (Fc.gamma.R) (C1q) Median % 6.25076 0.757259 1.24205 2.06056 1.50084 Area Range 0.069-17.073 0-9.646 0-17.799 0-24.531 0-17.069 % Change -- 88 80 67 76 Control p < 0.0001 p < 0.0001 p < 0.003 p < 0.0001 IgG2a % Change -- -- -- 165.9 120.8 3D6 IgG1 Number 32 34 36 36 34

[0374] The above results indicate that all of the 3D6 antibodies (IgG2a, IgG1 and mutants) significantly reduced amyloid burden relative to negative controls. Differences between the tested antibodies were not statistically significant.

[0375] The effect of the 3D6 derivative antibodies was then tested on vascular amyloid ratings. Table 13 shows the number of mice with the indicated vascular amyloid rating and the percentage of animals with a rating of 4 or greater (p values indicate significant difference compared to 3D6 IgG2a antibody).

TABLE-US-00087 TABLE 13 % of Mice Having Vascular Amyloid Moderate Percentage with None-little (0-3) (4+) moderate rating Control IgG2a 11 24 69 p < 0.0001 3D6 Control IgG2a 27 7 21 -- 3D6 Control IgG1 12 25 68 p < 0.0001 3D6 1m (Fc.gamma.R) IgG1 15 21 58 p < 0.0016 3D6 3m (C1q) IgG1 20 17 46 <0.0434

[0376] The above data show that the positive control 3D6 IgG2a significantly reduced vascular amyloid relative to the irrelevant IgG2a antibody. The reduction with 3D6 IgG2a was also statistically significant relative to that with 3D6 IgG1, 3D61 m IgG1 and 3D6 3 m IgG1. Differences between 3D6 IgG1, 3D61 m IgG1 and 3D6 3 m IgG1 and control IgG2a were not statistically significant.

[0377] To determine whether the 3D6 antibody derivatives cause microhemorrhage in mice, hemosiderin levels, a marker for microhemorrhage, were examined in brain sections of mice treated with 3 mg/kg antibody. Staining was carried out with 2% potassium ferrocyanide in 2% hydrochloric acid, followed by a counterstain in a 1% neutral red solution. Table 14 indicates the percentage and absolute number of mice with the indicated level of hemosiderin staining. The results demonstrate that 3D6 .mu.m IgG1 (Fc.gamma.R) and 3D6 3 m IgG1 (C1q), which are shown above to be effective in clearing amyloid plaques, reduce microhemorrhage levels relative to 3D6 IgG2a. Differences between 3D6 IgG1, 3D6 .mu.m IgG1 and 3D6 3 m IgG1 did not reach statistical significance, although the difference between 3D61m IgG1 and 3D6 IgG1 showed a trend. (p values indicate significant difference compared to 3D6 IgG2a antibody).

Phagocytosis Assays

Materials and Methods

[0378] Ex vivo plaque phagocytosis assays: Frozen brain sections from PDAPP mice were pre-incubated with 3D6 IgG1 and the effector function mutants described in Table 10 (3D61 m (Fc.gamma.RI) and 3D6 3 m (C1q), both mouse IgG1 isotype). 3D6 IgG2a was used as a positive control and irrelevant IgG1 and IgG2a antibodies were used as isotype controls. Sections were treated with 0.3 or 3 .mu.g/ml antibody for 30 minutes prior to addition of mouse microglia, at 5% CO.sub.2 at 37 C. The co-cultures were extracted the next day. Remaining A.beta. was measured by ELISA (266 antibody for capture, and 3D6-B for reporter) to assess A.beta. clearance.

[0379] Phagocytosis of murine IgG2a derivatives was tested. These experiments included: 3D6 IgG2a (positive control); non-specific IgG2a (negative control); 3D6 .mu.m (Fc.gamma.R1, IgG2a isotype); and 3D6 4 m (Fc.gamma.R1/C1q) antibodies. Conditions were similar to those described above.

[0380] Non-plaque phagocytosis was additionally determined for humanized 3D6 (Hu 3D6 IgG1) and the effector mutants described in Table 10 (Hu 3D6 2 m IgG1, Hu 3D6 3 m IgG1, and Hu 3D61 m IgG4). The negative control was an irrelevant human IgG1 antibody. Assay and detection conditions were otherwise the same.

[0381] In vitro assays: For the mouse antibody assays of fluorescently conjugated bead phagocytosis, 10 .mu.M FluoroSphere particles (5.times.10.sup.6) were opsonized with 1 mg/ml of mouse F(ab'2), 3D6 IgG2a, 3D6 IgG1, or the 3D6 Fc.gamma.R mutant for 2 hrs at RT with rotation. Following 2 hrs, beads were washed with 1 ml of PBS 3 times to remove unbound IgG. Opsonized particles were added (1:10) to mouse microglia for the murine 3D6 Ig2a (3D62a) experiments. Beads were incubated with the cells for 90 min at 37 C. Unbound particles were then washed away with PBS. Cells were stained with DiffQuick for 30 sec for each stain and phagocytosis was visualized by light microscopy. Controls for this assay were un-opsonized beads (unlabelled) (to detect non-specific engulfment) and pre-treatment with human Fc-fragments (3D62a+FC)(to block Fc.gamma.R1).

[0382] For humanized antibody assays, conditions and detection were the same. However, the antibodies were: no antibody (unlabelled; negative control), irrelevant human IgG1 (Human IgG1; positive control), Hu 3D6 IgG1, Hu 3D6 2 m IgG1, Hu 3D6 3 m IgG1, and Hu 3D6 .mu.m IgG4. The phagocytic cells were human THP-1 cells (differentiated with PMA).

Results

[0383] Ex vivo plague phagocytosis assays: The murine 3D6 IgG1 antibody and its effector mutants (3D61 m (Fc.gamma.R1) and 3D6 3 m (C1q)) were assayed to assess their ability to facilitate amyloid clearance (see FIG. 16). The 3D6 IgG2a antibody stimulated more robust clearance than 3D6 IgG1, 3D61 m (Fc.gamma.R1) and 3D6 3 m (C1q). Stimulation of phagocytosis by 3D6 IgG1, 3D6 .mu.m (Fc.gamma.R1) and 3D6 3 m (C1q) was greater than the negative control. Mutations to the Fc domain of 3D6 IgG1 do not appear to significantly dampen its ability to stimulate clearance in the ex vivo clearance assay.

[0384] For the IgG2a 3D6 derivatives, the mutants stimulated clearance equivalent to wild-type 3D6 IgG2a and to a greater degree relative to an irrelevant IgG2 isotype matched control (see FIGS. 17A & B). Thus, neither of the mutants completely inhibited A.beta. phagocytosis.

[0385] In the humanized antibody assays, mutations to the effector region of the Hu 3D6 IgG1 retained significant clearing activity relative to the negative control. Hu 3D6 IgG1 stimulated clearance in the ex vivo A.beta. plaque clearance assay, and the effector region mutants had moderately impaired function. Hu 3D6 IgG4 induced phagocytosis to the same extent as Hu 3D6 IgG1, and mutation to the IgG4 hinge region of 3D6 did not appear to change its effector function (see FIG. 18).

[0386] In vitro bead phagocytosis assays: To determine if the ex vivo results were specific for A.beta. clearance and whether the Fc mutation in the 3D6 IgG1 altered its effector function, non-specific Fc-mediated bead phagocytosis assays were performed. In the mouse antibody bead phagocytosis assay, the 3D6 IgG2a isotype antibody mediated more efficient phagocytosis than 3D6 IgG1 (see FIG. 19). The Fc mutation in 3D6 IgG1 did not significantly diminish the ability to stimulate phagocytosis, as compared to the positive control 3D6 IgG2a, indicating that the Fc mutation in 3D6 IgG1 was moderately effective in reducing phagocytosis.

[0387] In the humanized antibody assay, the effect of the Fc mutation seen in the ex vivo plaque phagocytosis assay was verified on Fc-mediated bead phagocytosis. Again, the mutations in the Fc portion of humanized 3D6 diminished its ability to mediate phagocytosis of fluorescent beads and there was no significant difference between the 2 m and 3 m mutants. Again, the theoretically ineffective IgG4 isotype mediated removal to the same extent as the IgG1 isotype (see FIG. 20). Mutation to the IgG4 hinge region of 3D6 does not appear to change its effector function.

Example 7

C1q Binding Ability of Humanized 3D6 Derivatives

[0388] The humanized 3D6 derivatives were tested for ability to bind C1q and induce a complement response. A standard C1q dilution series protocol was followed, as described below. Similar protocols are described, e.g., in Idusogie et al. (2000) J. Immunol. 164: 4178-4184.

[0389] Purified A.beta. was coated on to ELISA plates and exposed to one of the following humanized 3D6 antibodies at the concentrations indicated in FIG. 21: Hu 3D6 2 m (IgG1), Hu 3D6 3 m (IgG1), Hu 3D6 .mu.m (IgG4), and unmodified Hu 3D6 (IgG1). The ELISA plates were washed and then blocked with 0.02% Casein solution in PBS for 3 to 24 hours with slow agitation. The blocking solution was removed with another step of washing.

[0390] Next, purified human C1q (191391, MP Biomedicals) was added to the ELISA plates, with 2 ug C1q/ml assay buffer starting the 2.times. dilution series. C1q was allowed to bind for 2 hours with agitation. Following another wash step, 100 .mu.l/well anti-C1q antibody (Rb anti human C1q FITC conjugated cat# F010 DBS (dbiosys.com)) used at 1:200 was added for 1 hour with agitation. Results were compared to a blank with no anti-C1q antibody.

[0391] As shown in FIG. 21, the humanized 3D6 derivative antibodies did not significantly interact with C1q. This is in contrast to bapineuzumab, which does not have mutations in the Fc region.

[0392] The derivative antibodies were tested for ability to induce complement-mediated lysis of HEK 293 cells expressing A.beta. on the surface. A standard .sup.51Cr release assay was used, as described in Phillips et al. (2000)Cancer Res. 60:6977-84; Aprile et al. (1981) Clin. Exp. Immunol. 46:565-76.

[0393] The target cells were HEK293 cells (ATCC, CRL-1573) that expressed a fusion protein with the A.beta. epitope detected by 3D6 (DAEFR (SEQ ID NO: 94)) on the surface. The A.beta.-containing sequence was inserted into the pDisplay vector (Invitrogen). The pDisplay vector was altered to remove the HA tag and instead start with the A.beta.-containing peptide after leader sequence. A stable pool of HEK 293 was moved forward to the ADCC assay.

[0394] For labeling, 10.sup.7 cells were suspended in 2 ml RPMI 10% FCS and added 250uCi of .sup.51Cr (NEN catalog #NEZ-030; sodium.sup.51chromate in saline). Cells were incubated for 1 hour at 37 C with occasional agitation. At the end of the incubation, 10 ml RPMI with 10% FCS was added. Cells were spun down so the supernatant could be removed, and resuspended in 10 ml RPMI containing 10% FCS. Cells were again incubated, at room temperature for 1.5 hours with occasional agitation, to allow excess .sup.51Cr to bleed from the cells. Target cells were washed 3 times with 10 ml RPMI, and a final time in 10 ml RPMI containing 10% FCS. Cells were resuspended in RPMI with 10% FCS to a concentration of 10.sup.6 cells/ml.

[0395] Effector cells were collected from human blood. Briefly, blood was diluted 1:1 with PBS and layered over Ficoll (Sigma Histopaque 1077). The column was spun for 20 min, 1200.times.g, with no brake at 20 C. Cells at the interface were collected; washed once with 2-3 volumes PBS, and twice with RPMI containing 10% FCS. NK enrichment is detected with antibodies to CD3 and CD56.

[0396] Effector cells and target cells were added to 96 well plates at a ratio of 25:1 (effector:target) in a total volume of 200 .mu.l. The following control samples were included: Spontaneous lysis (containing target cells with no effectors) and Total lysis (leave wells empty) was included. The cells were incubated for 5 hours at 37 C. Just before harvest, 100 .mu.l 0.1% Triton X-100 was added to the Total lysis sample to release .sup.51Cr. The reactions were harvested onto filter units with a Skatron harvester (Molecular Devices) and total .sup.51Cr was detected.

[0397] To calculate % lysis, the average cpm and standard deviation was determined for each sample. The % Maximum .sup.51Cr Release is determined with the following formula:

(Experimental-Spontaneous).times.100(Total-Spontaneous)

[0398] Consistent with the results of the C1q binding assay, the humanized 3D6 effector function mutant derivative antibodies were not effective at inducing complement lysis of the A.beta.-expressing HEK 293 cells (see FIG. 22).

Example 8

ELISA Assay Measuring C1q Binding Ability of Murine 3D6 Derivatives

Materials and Methods

[0399] A 96-well fluorescent plate was coated with 1, 3, or 6 .mu.g/ml of various antibodies in 100 .mu.l well coating buffer overnight at 4 C. After coating, plates were washed and blocked with 200 .mu.l Casein Elisa Block for 1 hr at RT. Plates were washed and 100 .mu.l of 2 .mu.g/ml human C1q in diluent buffer was added for 2 hrs at RT. After 2 hrs, plates were washed and FITC-labelled rabbit anti-C1q (1:1000) was added for 1 hr. Plates were washed twice and read at 494/517 on the fluorescent plate reader in PBS. The following mouse antibody samples were tested: IgG2a, IgG2b, 3D6 IgG2a, IgG1, 3D6 IgG1, and the 3D6 IgG1 C1q mutant.

Results

[0400] The highest level of C1q binding was observed for IgG2a and 3D6 IgG2a (see FIG. 23). C1q binding to IgG1 and 3D6 IgG1 was significantly lower than IgG2a. The mutation in 3D6 IgG1 C1q binding domain suppressed this binding further.

Example 9

Contextual Fear Conditioning (CFC) Assay

[0401] Tg2576 transgenic mice and wild-type littermate controls were individually housed for at least 2 weeks prior to any testing and allowed ad libitum access to food and water. CFC occurred in operant chambers (Med Associates, Inc.) constructed from aluminum sidewalls and PLEXIGLAS ceiling, door and rear wall. Each chamber was equipped with a floor through which a foot shock could be administered. In addition, each chamber had 2 stimulus lights, one house light and a solenoid. Lighting, the footshock (US) and the solenoid (CS) were all controlled by a PC running MED-PC software. Chambers were located in a sound isolated room in the presence of red light.

[0402] Mice (n=8-12/genotype/treatment) were trained and tested on two consecutive days. The Training Phase consisted of placing mice in the operant chambers, illuminating both the stimulus and house lights and allowing them to explore for 2 minutes. At the end of the two minutes, a footshock (US; 1.5 mAmp) was administered for 2 seconds. This procedure was repeated and 30 seconds after the second foot shock the mice were removed from the chambers and returned to their home cages.

[0403] Twenty hours after training, animals were returned to the chambers in which they had previously been trained. Freezing behavior, in the same environment in which they had received the shock ("Context"), was then recorded using time sampling in 10 seconds bins for 5 minutes (30 sample points). Freezing was defined as the lack of movement except that required for respiration. At the end of the 5 minute Context test mice were returned to their home cages.

[0404] Approximately 20-week old wild-type mice and Tg2576 transgenic mice were administered a single dose of treatment antibody by intraperitoneal injection at 24 hours prior to the training phase of the CFC. Treatment antibodies were: (i) non-specific IgG1 antibody; (ii) Hu 3D6 3 m (Fc.gamma.R) (also called AAB-003); and (iii) bapineuzumab (also called AAB-001).

[0405] FIG. 24 demonstrates the results. Control-treated wild type mice showed about 40% freeze, while in comparison, control-treated transgenic mice exhibited a severe deficit in contextual memory. When administered at 30 mg/kg, the Hu 3D6 3 m antibody restored cognitive function to wild type levels. Furthermore, the effector function mutant had the same effect on contextual memory as the parent antibody, bapineuzumab.

[0406] The effect of the Hu 3D6 3 m antibody on contextual memory was observed over time. FIG. 25 illustrates that treatment with 30 mg/kg Hu 3D6 3 m antibody provided wild type levels of cognition at least 5 days post-administration.

[0407] In summary, the above examples show that Hu 3D6 3 m results in similar cognition improvements as bapineuzumab. This is despite the fact that the derivative antibody does not significantly bind to Fc receptors or C1q, or induce phagocytosis or ADCC activity.

Mouse Studies with 3D6 4 m (Fc.gamma.R/C1q) IgG2a and Hu 3D6 3 m IgG1 (AAB-003)

Study Design

[0408] One-year old PDAPP mice are exposed to a 6 month treatment paradigm with control; 3D6 4 m (Fc.gamma.R/C1q) IgG2a; or Hu 3D6 3 m IgG1 (see Table 10). Negative controls include a mouse IgG2a antibody and a human IgG1 antibody to an irrelevant, non-amyloid epitope. Positive controls include 3D6 IgG2a and Hu 3D6 IgG1. The mice are split into dosage cohorts and injected IP at weekly intervals with 3, 30, or 300 mg/kg of the indicated antibody. Experimental conditions are as described in Example 5.

[0409] After 6 months, the mice are sacrificed and brain tissue harvested as described above. Tissues are examined for cortical and hippocampal Ab and amyloid burden, vascular amyloid, and microhemorrhage.

Example 11

Cynomolgus Monkey Studies with Hu 3D6 3 m IgG1 (AAB-003)

Study Design

[0410] Cynomolgus monkeys are treated with Hu 3D6 3 m IgG1 (AAB-003). The negative control includes a human IgG1 antibody to an irrelevant, non-amyloid epitope. The positive control include Hu 3D6 IgG1 (Bapineuzumab). Monkeys are split into dosage cohorts receiving either 15, 50, or 150 mg/kg of the indicated antibody. Each cohort is further split into IV and SC administration groups.

[0411] Monkeys are injected weekly for 13 weeks, with a 2 month observation period. At the end of the study, the monkeys are sacrificed and brain tissue harvested. Tissues are examined for cortical and hippocampal A.beta. and amyloid burden, vascular amyloid, and microhemorrhage.

Example 12

Single Ascending Dose (SAD) Study in Humans of Hu 3D6 3 m (AAB-003) Antibody

[0412] Mild to moderate Alzheimer's patients, including ApoE4 carriers and non-carriers, are divided into cohorts for intravenous (IV) or subcutaneous (SC) injection with AAB-003 antibody. The cohorts are given a single dose with a 12 month follow up, and monitored throughout by an independent safety monitoring committee.

[0413] The goal of the study is to increase the exposure equivalent to at least 5 mg/kg of intravenous Bapineuzumab (unless signs of vasogenic edema are observed). At this dose of Bapineuzumab, VE was observed in 3 of 10 patients.

[0414] The SC cohorts include at least two subcutaneous dosage levels. These patients are be observed for bioavailability of the antibody and linearity thereof.

[0415] All patients are screened (e.g., for ApoE status) and monitored as described in Example 1. For all cohorts, safety monitoring includes MRI monitoring. MRI results are compared to those from the Bapineuzumab study described in the above examples. Efficacy is measured by cognitive metrics (e.g., NTB, DAD, ADAS-Cog,); plasma A.beta. levels; CSF levels of amyloid, tau, and phosphotau; and amyloid imaging.

[0416] Certain biomarkers are tracked in each patient during the study. Biomarkers to support A.beta. binding by the antibody include A.beta.40 and A.beta.42 in the CSF and plasma, and amyloid plaque imaging, e.g., by PET. Biomarkers pointing to disease modification include MRI, CSF tau and phosphotau levels, and again, amyloid plaque imaging.

Pharmacokinetic Profiles of Hu 3D6 3 m (AAB-003) in Tg2576 and Wild Type Mice

[0417] Tg2576 transgenic mice and wild type controls were dosed with AAB-003 subcutaneously (SC) or intraperitoneally (IP) to determine bioavailability of the antibody. The profile was typical for therapeutic antibody.

[0418] AAB-003 was eliminated slowly, with a T.sub.1/2 of 66-160 hours. There was low volume distribution (71-96) and good exposure (as measured by AUC).

[0419] Some differences between the wild type and transgenic mice were apparent. For example, wild type mice had higher AUC and T.sub.1/2. The transgenic mice had slightly higher levels of anti-AAB-003 antibodies.

Example 14

Pharmacokinetic Profiles of Hu 3D6 3 m (AAB-003) in Cynomolgus Monkeys

[0420] 10 mg/kg Hu 3D6 3 m or bapineuzumab were administered intravenously (IV) to cynomolgus monkeys (3 animals/antibody treatment) to compare the pharmacokinetic profiles and determine whether the effector function mutation had any effect. The results were comparable between the two antibodies, and typical for therapeutic antibodies in general. There was low clearance (0.16.+-.0.06 ml/hr/kg), small volume of distribution (.about.62 ml/kg), and long elimination half-life (309.+-.226 hours). One of the three animals tested positive for antibodies against AAB-003.

[0421] The same antibody doses were administered subcutaneously (SC). Bioavailability was good, approximating 69%, and the half-life ranged from 21-445 hours. Two of the three animals tested positive for antibodies against AAB-003.

Example 15

Effect of Fc Mutations on the Effector Function of an Anti-Lewis Y Antibody

[0422] To determine the effect of mutations in the low hinge region of human IgG1 on the effector function of antibodies with different antigen specificity, we designed antibodies to the Lewis Y (LeY) antigen. LeY is a type 2 blood group related difucosylated oligosaccharide that is mainly expressed in epithelial cancers, including breast, pancreas, colon, ovary, gastric, and lung. LeY does not appear to be expressed on tumors of neuroectodermal or mesodermal origin.

[0423] The anti-LeY Ab02 antibody was generated with one of three heavy chain constant regions: (i) wild type human IgG1; (ii) wild type human IgG4; and (iii) human IgG1 with two effector region mutations, L234A and G237A (see SEQ ID NOs:50 and 51). IgG4 has been shown to have reduced effector function in other systems.

[0424] For the ADCC (antibody-dependent complement cytotoxicity) assay, LeY-overexpressing N87 human gastric adenocarcinoma cells were used as target cells, and freshly isolated human PBMC were used as effector cells. Effector and target cells were plated at a ratio of 50:1 in 96 well plates. Antibody was applied at varying concentrations (0.1, 1 and 10 .mu.g/ml) in triplicate with medium, effector and target cell controls, and antibody controls. The ADCC activities of anti-Lewis Y Ab02 versions are presented in FIG. 26.

[0425] For the CDC (complement dependent cytotoxicity) assay, LeY positive tumor cells (A431 LeY) were plated in 96 well plates with varying amount of antibody (0.1, 1 and 10 .mu.g/ml). Diluted human complement (1:100), was added to each well. Tests were done in triplicate at a final volume of 100 .mu.l/ml with medium, cells alone, and antibody and complement controls. After 4 hours incubation at 37 C, plates were removed and equilibrated to 22 C.

[0426] An equal volume of CytoTox-One.TM. was added to each well, and incubated for 10 minutes at 22 C. As a positive control, 2 .mu.l of lysis buffer per well (in triplicate) was added to generate a maximum LDH (lactate dehydrogenase) release in control wells. The enzymatic reaction was stopped by adding 50 .mu.l of stop solution. The resulting fluorescence was recorded with an excitation wavelength of 560 nm and an emission wavelength of 590 nm. The % of complement-related cell lysis was calculated as % of total LDH release (FIG. 27).

[0427] In spite of the L234A and G237A mutations in IgG1, the mutant antibody fully retained its capacity to mediate both ADCC and CDC against Lewis Y expressing tumor cells, as compared to wild type IgG1.

Example 16

Effect of Fc Mutations on the Effector Function of Anti-5T4 Antibody

[0428] To investigate further the effect of Fc mutations in human IgG1 on the effector function of antibodies with different antigen specificity, we designed antibodies to the oncofetal protein 5T4. 5T4 is a tumor-associated protein displayed on the cell membrane of various carcinomas, and is a promising target for anti-tumor vaccine development and for antibody directed therapies.

[0429] The anti-5T4 antibody was generated with different combinations of mutations in the heavy chain constant region. The heavy chains used were: (i) wild type human IgG1; (ii) wild type human IgG4; (iii) human IgG1, L234A and L235A; (iv) human IgG1, L234A and G237A; (v) human IgG1, L235A and G237A; and (vi) human IgG1 with three effector region mutations, L234A, L235A, and G237A (see SEQ ID NOs:62 and 63).

[0430] Human breast carcinoma cell line MDAMB435, stably transfected with 5T4 antigen, was used for the ADCC and CDC assays. The ADCC assay of anti-5T4 antibodies was as described in Example 15, using freshly isolated human PBMC as effector cells at an effector:target cell ratio 50:1. MDAMB435-Neo transfected cells were used as a negative control. The results of ADCC activity (maximum specific cytotoxicity at the antibody concentration 10 ug/ml) are summarized in Table 15.

TABLE-US-00089 TABLE 15 ADCC activity of anti-5T4 antibodies against 5T4 positive and negative human breast carcinoma cell line MDAMB435 MDAMB345-5T4 MDAMB-Neo Antibody % specific cytotoxicity % specific cytotoxicity 5T4-IgG1wt 81 3 5T4-IgG1 78 2 L234A/G237A 5T4-IgG1 15 2 L234A/L235A 5T4-IgG1 27 2 L235A/G237A 5T4-IgG1 2 2 L234A/L235A/G237A 5T4-IgG1 5 3 N297A 5T4-IgG4 2 2

[0431] To evaluate an effect of Fc mutations on the complement induced cytotoxicity, human breast carcinoma MDAMB435-5T4 cells were incubated with diluted human complement as described in the Example 15. The results of CDC assays are presented in the Table 16.

TABLE-US-00090 TABLE 16 CDC activity of anti-5T4 antibodies against 5T4 positive and negative human breast carcinoma cell line MDAMB435 MDAMB345-5T4 MDAMB-Neo Antibody % specific cytotoxicity % specific cytotoxicity 5T4-IgG1wt 90 2 5T4-IgG1 72 2 L234A/G237A 5T4-IgG1 5 2 L3234A/L235A 5T4-IgG1 19 2 L235A/G237A 5T4-IgG1 1 1 L234A/L235A/G237A 5T4-IgG1 1 1 N297A 5T4-IgG4 1 1

[0432] The introduction of two mutations in the low hinge region of human IgG1 in any of the combinations tried (L234A/L235; L234A/G237A; L235A/G237A) only partially reduced ADCC and CDC activity with L235A/G237A showing the higher residual effecter function capabilities. However, anti-5T4 antibody with three mutations in the IgG1 low hinge region (L234A/L235A/G237A) demonstrated completely abolished ADCC and CDC activities.

Conclusions

[0433] The Examples provide a number of comparisons of Fc region mutant antibodies with different antigen specificities. Example 6 describes an ADCC assay using A.beta.-specific antibodies with IgG1 Fc mutations at either L234A and G237A (double mutant), or L234, L235A, and G237A (triple mutant). Both the double and triple mutants had significantly reduced function (see FIG. 22). Example 15 describes ADCC and CDC assays using LeY-specific antibodies with IgG1 mutations at L234A and G237A. In this case, the mutant antibody retained effector function (see FIGS. 26 and 27). Finally, Example 16 compares IgG1 Fc mutants of 5T4-specific antibodies. Each of the double mutants (L234A/L235; L234A/G237A; L235A/G237A) retained more effector activity than the triple mutant (L234A/L235A/G237A) (see Tables 15 and 16). The effector activity of the L234A/L235 double mutant, however, was reduced to nearly the same level as that of the triple mutant.

[0434] The above results demonstrate that the effect of the hinge-region mutations can depend on a number of factors, including target antigen density on the cell surface. However, the data indicate that disruptions at all three positions are necessary to eliminate effector activity.
