BACKGROUND

1. Field of the Invention

[0004] The present disclosure relates to methods of detecting mutations associated with and diagnosing CD55 deficiency, hyperactivation of complement, angiopathic thrombosis and protein losing enteropathy (CHAPLE), methods for the treatment of CHAPLE, and therapeutic compositions for treating CHAPLE.

2. Background Invention

[0005] A rare disease is generally accepted as being any disease that affects a small percentage of the population, but there is no single definition. For example, rare diseases are referred to as Orphan Diseases in the United States and defined as conditions that affect fewer than 200,000 people in the United States. Orphan diseases include, inter alia, cystic fibrosis, Lou Gehrig's disease, and Tourette's syndrome, Hamburger disease, Job syndrome, atypical hemolytic uremic syndrome, paroxysmal nocturnal hemoglobinuria, acromegaly (or "gigantism"). An accurate diagnosis of a rare disease can generally take up to 5 years because early stage symptoms could be absent, masked, misunderstood, or confused with other more prevalent diseases. New orphan diseases are discovered each year and are typically caused by inherited gene mutations.

[0006] Protein-losing enteropathy (PLE) is characterized by excessive loss of serum proteins through the gastrointestinal (GI) tract resulting in hypoproteinemia, edema, and, in some cases, pleural and pericardial effusions. Pathogenic mechanisms of PLE can involve (1) impaired barrier function of the GI mucosa, often in association with inflammatory bowel disease (IBD) and (2) impaired lymphatic drainage, either due to primary intestinal lymphangiectasia, or secondary to systemic conditions that impair lymph flow, such as cardiac diseases. Although most cases of PLE are sporadic, primary intestinal lymphangiectasia has been reported in multiple siblings of several families, suggesting a genetic etiology in certain cases.

[0007] Identifying rare monogenetic defects can elucidate the pathophysiology of disease, improve diagnosis, and promote targeted therapies for specific inherited syndromes and related common diseases. These efforts have been greatly aided by massively parallel DNA sequencing technologies, increasingly comprehensive datasets of human genetic variation, and new gene validation technologies. Several intestinal diseases related to early onset IBD (EO-IBD) have been attributed to Mendelian gene defects. Recently, a loss-of-function (LOF) mutation in the plasmalemma vesicle associated protein gene was reported in a young infant with severe PLE associated with disruption of endothelial fenestrated diaphragms in the intestinal vasculature, demonstrating that PLE may also arise from Mendelian gene defects.

[0008] The complement system is a vital part of the immune system of the body that protect against pathogens (e.g., bacteria, fungi, viruses, etc.). The complement system is a complex collection of greater than 25 plasma proteins and membrane factors. The complement components interact through a series of intricate enzymatic cleavages and membrane binding events, which result in the production of products with opsonic, immunoregulatory, and lytic functions. Because complement has potent effects on immunity and cell physiology, it must be tightly controlled.

[0009] The complement cascade includes three pathways referred to as the classical pathway, the lectin pathway, or the alternative pathway. The classical pathway of complement activation is initiated or triggered by an antibody recognizing (i.e., binding) an antigen located on a target cell. The lectin pathway of complement activation is initiated or triggered by the binding of a mannose-binding protein that is present in blood plasma to mannose-containing proteoglycans on the surfaces of bacteria and yeast, which has structural similarities to the antibody initiation of the classical pathway. As such, the lectin pathway then proceeds in a similar fashion as the classical pathway. The alternative pathway of complement activation is initiated or triggered by constituents of bacterial surfaces, as will be discussed in greater detail below.

[0010] Each of the three pathways lead to the covalent bonding of a particular fragment of a complement component (i.e., the C3b fragment of C3) to the pathogen surface, which is recognized by C3b receptors on macrophages and neutrophils. This deposition of C3b fragments on the surface of the pathogen is mediated by a C3 convertase, which is a protease that cleaves the complement component C3 to yield C3a and C3b. The C3b fragment is an osponin, which mediates interaction with phagocytes (e.g., macrophages, neutrophils, and dendritic cells, which promote inflammatory immune reactions) through their C3b receptors. As such, the opsonized pathogens are targeted by phagocytes. The opsonic function of C3b is one of the most important functions of the complement system, and its disruption leads to a susceptibility to a broad range of pathogens. C3b can then be progressively broken down by Factor I (a protease) and a cofactor (i.e., Factor H, CR1, MCP, or C4BP) to iC3b, then C3c+C3dg, and finally C3d. The C3a fragment is a potent anaphylatoxin that stimulates mast cell degranulation, which results in the release of histamine from basophils and mast cells. Histamine enhances vascular permeability, smooth muscle contraction, and leukocyte activation, as well as being an attractant (chemotractic factor) for granulocytes (e.g., neutrophils, eosinophils, basophils) and macrophages.

[0011] Complement component C3, which is the most abundant complement protein and is abundantly present in plasma, is spontaneously hydrolyzed (the alternative pathway). In particular, there is a spontaneous cleavage of a thioester bond in C3 that forms C3i or C3(H.sub.2O). The alternative pathway is facilitated by surfaces that support the binding of activated C3 (i.e., C3i or C3(H.sub.2O)), as well as surfaces that have neutral or positive charge characteristics (such as those found in bacteria). The plasma protein Factor B binds to the C3i surface bound protein. Factor D then subsequently cleaves Factor B, thereby producing Ba and Bb. The Bb fragment remains bound to C3i to form a C3iBb, which is a C3 convertase that functions as described above and may be referred to as the alternative pathway C3 convertase. The alternative pathway C3 convertase is stabilized by the binding of properdin (although not required). The alternative pathway C3 convertase has an amplification affect because each of the fluid-phase C3 convertase (i.e., the alternative pathway C3 convertase) can cleave multiple C3 proteins into C3a and C3b, which results in the deposition of additional C3b covalently bound to the surface (e.g., a bacterial surface). In a similar fashion, the alternative pathway C5 convertase is formed by the addition of a second C3b monomer to the alternative pathway C3 convertase (i.e., add C3b to C3iBb, which is referred to as (C3b).sub.2Bb), which is also stabilized by the binding of properdin (although not required). The alternative pathway C3 convertase bind and cleaves C5.

[0012] The classical pathway C3 convertase is formed when complement component C1 (comprising a complex of C1q, C1r, and C1s) is activated by an antibody-target-antigen complex (e.g., a microbial antigen). That is, the binding of C1q to the antibody-target-antigen complex results in a conformational change in C1, which activates C1r. Activated C1r cleaves/activates C1s. Active C1s is a serene protease that cleaves complement component C4 into C4b and C4a and complement component C2 into C2b and C2a. C4b fragments contain a reactive thiol that readily forms amide or ester bonds with suitable molecules on a target surface (e.g., a microbial cell surface). Activated C4b and C2a form the classical pathway C3 convertase, which functions as described above. When a C3b monomer is added to the classical pathway convertase, the classical pathway C5 convertase (C4b, C2a, C3b) is formed.

[0013] As discussed above, the lectin pathway is homologous to the classical pathway with a mannose-binding lectin (MBL, which is similar to C1q) to mannose residues on the surface of a pathogen. This binding activates the MBL-associated serine proteases MASP-1 and MASP-2 (which are very similar to C1r and C1s, respectively). This complex functions in the same fashion as C1 in the classical complement pathway.

[0014] The alternative, classical, and lectin pathway C5 convertases cleave C5, which is found in normal human serum, into C5a and C5b. Similar to C3a, C5a is a potent anaphylatoxin and chemotactic factor. C5a receptors are present on the surfaces of: bronchial and alveolar epithelial cells, bronchial smooth muscle cells, eosinophils, mast cells, monocytes, neutrophils, and activated lymphocytes.

[0015] C5b binds to C6 and C7 to form a complex that interacts with C8 and subsequently numerous C9 proteins, thereby producing a membrane attack complex (MAC) or lytic unit (C5b,6,7,8).sub.1(9).sub.n(n=10-16 molecules) on the targeted cell membrane, which is a pore that extends through the cell membrane. When a sufficient number of MACs are present in the target cell membranes, hypotonic lysis of the targeted cell is achieved. C5a and C5b-9 also amplify the release of downstream inflammatory factors (e.g., hydrolytic enzymes, reactive oxygen species, arachidonic acid metabolites and various cytokines).

[0016] The complement system provides a robust defense against infection. However, misregulation or inappropriate activation of the complement system is associated with the pathogenesis of a variety of disorders including (e.g., rheumatoid arthritis; lupus nephritis; asthma; ischemia-reperfusion injury; atypical hemolytic uremic syndrome (aHUS); dense deposit disease; paroxysmal nocturnal hemoglobinuria (PNH); macular degeneration; hemolysis, elevated liver enzymes, and low platelets syndrome; thrombotic thrombocytopenic purpura; spontaneous fetal loss; Pauci-immune vasculitis; epidermolysis bullosa; recurrent fetal loss; multiple sclerosis; traumatic brain injury; and injury resulting from myocardial infarction, cardiopulmonary bypass and hemodialysis). Complement inhibition has been demonstrated to be effective in treating several complement-associated disorders in animal models and in humans (see, e.g., Rother et al. (2007) Nature Biotechnology 25(11):1256-1264; Wang et al. (1996) Proc Natl Acad Sci USA 93:8563-8568; Wang et al. (1995) Proc Natl Acad Sci USA 92:8955-8959; Rinder et al. (1995) J Clin Invest 96:1564-1572; Kroshus et al. (1995) Transplantation 60:1194-1202; Homeister et al. (1993) J Immunol 150:1055-1064; Weisman et al. (1990) Science 249:146-151; Amsterdam et al. (1995) Am J Physiol 268:H448-H457; and Rabinovici et al. (1992) J Immunol 149:1744 1750.

[0017] CD55 (decay accelerating factor or DAF) is a widely expressed GPI-linked cell surface protein that regulates complement activation by reducing the activity of C3 and C5 convertases and accelerating their disassembly. Specifically, DAF recognizes C4b and C3b fragments that are created during the C4 activation (classical complement pathway and lectin pathway) and C3 activation (alternate complement pathway). DAF interferes with the conversion of C2 to C2a through its interaction with the cell-associated C4b of the classical and lectin pathways. This prevents the formation of the C4b2a C3 convertase. Similarly, DAF interferes with the conversion of factor B to Bb by factor D through its interaction with C3b of the alternative pathway. This prevents the formation of the C3bBb C3 convertase of the alternative pathway. As a result, the amplification provided by 3C convertases of the complement cascade are limited by the interaction of DAF (or CD55) with C4b and C3b, which results in indirectly blocking the formation of the MAC. A rare CD55 deficiency on red blood cells (RBCs), known as the Inab phenotype, is detected by the loss of Cromer blood group antigens. This rare CD55 deficiency has been associated with complement dysregulation, formation of a strong RBC alloantibody agglutinin, and GI abnormalities. However, a disease resulting from the germline loss of CD55 has not been clearly defined to date.

[0018] As mentioned above, rare diseases are often misdiagnosed, and new rare diseases are regularly identified. For example, the present disclosure describes a newly identified rare disease--CHAPLE disease/syndrome. As such, there exists a need to accurately detect the mutations associated with CHAPLE disease/syndrome, as well as diagnose and treat individuals with CHAPLE disease/syndrome with a therapeutic composition.

SUMMARY

[0019] The present disclosure relates to the surprising and unexpected discovery of the cause of CHAPLE, and therefore, methods of diagnosing CHAPLE, as well as methods of treating patients with CHAPLE symptom(s) and methods of preventing a symptom(s) of CHAPLE in individuals predisposed to develop CHAPLE syndrome with a therapeutic composition.

[0074] FIGS. 12A and 12B. Model of CHAPLE syndrome molecular pathogenesis leading to PLE. In healthy individuals CD55 prevents complement activation and generation of anaphylatoxins. T cells produce an inflammatory cytokine mileu that is balanced towards production of IL10 and control of intestinal immune responses. CD55 further protects from complement activation on other host cells, including prevention of complement activation on endothelial cells. CD55 deficiency associated with CHAPLE syndrome results in increased complement activation and anaphylatoxin production. The lack of CD55 and signaling by anaphylatoxins produces an inflammatory environment characterized by low IL-10 production and increased TNF.alpha. production. Lower IL-10 production likely allows for further immunological activation, while TNF.alpha. drives an inflammatory environment and endothelial cell changes characterized by the down regulation of complement regulatory proteins CD46 and CD59 and skewing of tissue factor and thrombomodulin expression towards a procoagulative state. Lack of CD55 on endothelial cells further exasperates the changes caused by TNF.alpha. production leading to uncontrolled activation of the coagulation and complement cascades on endothelial surfaces. This directly leads to endothelial barrier damage and protein/fluid loss into interstitial spaces. The presence of high concentrations of retinoic acid in intestinal tissues drives the upregulation of CD55 and down regulation of thrombomodulin, likely accounting for the predisposition to intestinal manifestations in CHAPLE syndrome (A). Proinflammatory and procoagulant changes described in A, and various pathological processes driven by excessive complement effectors generated by immune response to the gut-microbiome lead to lymph vessel distortion and compromised lymphatic flow. Ensuing lymphangiectasia results in GI protein loss and malabsorption of fat and micronutrients. Aggravation of the mucosal edema due to hypoproteinemia and the pathological inflammation drives worsening enteropathy. Intraluminal complement activation likely impacts intestinal epithelial function. This, combined with hypercoagulability within blood vessels impairs circulatory dynamics thus aggravating the PLE (B).

[0076] The present disclosure is related, in part, to the surprising and unexpected discovery individuals afflicted with the above symptoms have a CD55 deficiency due to at least one CD55 gene mutations that results in the near to complete lack of expression of CD55 protein and/or the expression of a CD55 protein that has substantially diminished functional activity or that is devoid of functional activity.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entireties. In the case of conflict, the present specification, including definitions, will control. In addition, the examples are illustrative only and not intended to be limiting.

[0078] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise (such as in the case of a group containing a number of amino acids in which case each amino acid number falling within the range is provided), between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the invention.

[0079] The following terms are used to describe the present invention. In instances where a term is not specifically defined herein, that term is given an art-recognized meaning by those of ordinary skill applying that term in context to its use in describing the present invention.

[0080] The articles "a" and "an" as used herein and in the appended claims are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, "an element" means one element or more than one element.

[0081] The phrase "and/or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

[0082] As used herein in the specification and in the claims, "or" should be understood to have the same meaning as "and/or" as defined above. For example, when separating items in a list, "or" or "and/or" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as "only one of" or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of a number or list of elements. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., "one or the other but not both") when preceded by terms of exclusivity, such as "either," "one of," "only one of," or "exactly one of."

[0083] In the claims, as well as in the specification above, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving," "holding," "composed of," and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases "consisting of" and "consisting essentially of" shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.

[0084] As used herein in the specification and in the claims, the phrase "at least one," in reference to a list of one or more elements, should be understood to mean at least one element selected from anyone or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B," or, equivalently "at least one of A and/or B") can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

[0085] It should also be understood that, in certain methods described herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited unless the context indicates otherwise.

[0086] The phrases "pharmaceutically or pharmacologically acceptable" refer to molecular entities and compositions that do not preclude use in a human or animal.

[0087] The terms "co-administration" and "co-administering" or "combination therapy" refer to both concurrent administration (administration of two or more therapeutic agents at the same time) and time varied administration (administration of one or more therapeutic agents at a time different from that of the administration of an additional therapeutic agent or agents), as long as the therapeutic agents are present in the patient to some extent, preferably at effective amounts, at the same time. In certain preferred aspects, one or more of the present compounds described herein, are co-administered in combination with at least one additional bioactive agent, especially including an anticancer agent. In particularly preferred aspects, the co-administration of compounds results in synergistic activity and/or therapy, including anticancer activity.

[0088] The term "compound", as used herein, unless otherwise indicated, refers to any specific chemical compound disclosed herein and includes tautomers, regioisomers, geometric isomers, and where applicable, stereoisomers, including optical isomers (enantiomers) and other stereoisomers (diastereomers) thereof, as well as pharmaceutically acceptable salts and derivatives (including prodrug forms) thereof where applicable, in context. Within its use in context, the term compound generally refers to a single compound, but also may include other compounds such as stereoisomers, regioisomers and/or optical isomers (including racemic mixtures) as well as specific enantiomers or enantiomerically enriched mixtures of disclosed compounds. The term also refers, in context to prodrug forms of compounds which have been modified to facilitate the administration and delivery of compounds to a site of activity. It is noted that in describing the present compounds, numerous substituents and variables associated with same, among others, are described. It is understood by those of ordinary skill that molecules which are described herein are stable compounds as generally described hereunder. When the bond is shown, both a double bond and single bond are represented within the context of the compound shown.

[0089] The term "polypeptide" encompasses two or more naturally occurring or synthetic amino acids linked by a covalent bond (e.g., an amide bond). Polypeptides as described herein include full length proteins (e.g., fully processed proteins such as antibodies) as well as shorter amino acids sequences (e.g., fragments of naturally occurring proteins or synthetic polypeptide fragments such as antigen-binding fragments of antibodies).

[0090] The term "patient" or "subject" is used throughout the specification to describe an animal, preferably a human or a domesticated animal, to whom treatment, including prophylactic treatment, with the compositions according to the present disclosure is provided. For treatment of those conditions or disease states which are specific for a specific animal such as a human patient, the term patient refers to that specific animal. In general, in the present disclosure, the term patient refers to a human patient unless otherwise stated or implied from the context of the use of the term.

[0091] The term "effective" is used to describe an amount of a compound, composition or component which, when used within the context of its intended use, effects an intended result. The term effective subsumes all other effective amount or effective concentration terms, which are otherwise described or used in the present application.

[0092] The term "inflammatory bowel disease" refers to The term "lymphangiectasia" refers to a pathologic dilation of lymph nodes, which causes a disease known as "intestinal lymphagiectasia."

[0093] The term "intestinal lymphangiectasia" refers to a disease characterized by lymphatic vessel dilation, chronic diarrhea, and loss of proteins, such as serum albumin and globulin. Considered to be the cause of a chronic form of protein-losing enteropathy.

[0094] The term "enteropathy" refers to any pathology of the intestine.

[0095] The term "protein losing enteropathy" (PLE) refers to any condition of the gastrointestinal tract (e.g., damage to the gut wall) that results in a net loss of protein from the body. Symptoms include, e.g., diarrhea, fever, general abdominal discomfort, hypoproteinemia, and/or edema. See, also, the discussion of PLE above.

[0096] The term "thrombosis" refers to the formation of a blood clot inside a blood vessel, thereby obstructing blood flow through the circulatory system.

[0097] The term "thrombotic events" refers to the formation of a blood clot inside a blood vessel, thereby obstructing blood flow through the circulatory system

[0098] The term "thromboembolism" refers to the obstruction of a blood vessel by a blood clot that has become dislodged from another site in the circulatory system.

[0099] The term "hypoproteinemia" refers to a condition in which there is an abnormally low level of protein in the blood and is often accompanied with edema.

[0100] The term "angiopathic thrombosis" (or microangiopathic hemolytic anemia) refers to the pathology that relates from thrombosis in small blood vessels (such as capillaries and arterioles). The thrombosis is usually a consequence of endothelial cell injury, which results in fibrin exudation, fibrinoid necrosis, platelet aggregation, and thus, the thrombosis of small blood vessels

[0101] The term "hypogammaglobulinemia" refers to a type of hypoproteinemia, in which the level of gamma globulins is abnormally low, which results in primary immune deficiency disease.

[0102] The term "hypoalbuminemia" refers to a type of hypoproteinemia in which the level of albumin in the blood is abnormally low.

[0103] The term "hyperactivation of complement" refers to a medical sign in which the complement pathway is overly active.

[0104] The term "disease" refers to any condition that impairs the normal functioning of the body. As such, diseases are associated with dysfunctioning of the body's normal homeostatic processes.

[0105] The term "syndrome" refers to the association of several medical signs, symptoms, and/or other characteristics that often occur together, which may have a single or a multifactorial cause.

[0106] The term "antibody" is used in the broadest sense and specifically covers monoclonal antibodies (including full length monoclonal antibodies), polyclonal antibodies, multi-specific antibodies (e.g., bispecific antibodies), and antibody fragments so long as they exhibit the desired biological activity.

[0107] "Antibody fragments" (i.e., an antigen-binding fragment of an antibody), as defined for the purpose of the present disclosure, comprise a portion of an intact antibody, generally including the antigen binding or variable region of the intact antibody and optionally the Fc region of an antibody. Examples of antibody fragments include linear antibodies, single-chain antibody molecules (e.g., scFv), F(ab').sub.2 fragments, Fab' fragments, and multi-specific antibodies formed from antibody fragments. The antibody fragments may retain at least part of the hinge and optionally the C.sub.H1 region of an IgG heavy chain. The antibody fragments may retain the entire constant region of an IgG heavy chain, and include an IgG light chain.

[0108] The term "Fc region" is used to define a C-terminal region of an immunoglobulin heavy chain. Although the boundaries of the Fc region of an immunoglobulin heavy chain might vary, the human IgG heavy chain Fc region is usually defined to stretch from an amino acid residue at position Cys226, or from Pro230, to the carboxyl-terminus thereof. The Fc region of an immunoglobulin generally comprises two constant domains, C.sub.H2 and C.sub.H3.

[0109] The term "F(ab) fragment" is defined as a fragment of an immunoglobulin molecule that comprises the variable regions of a light chain and a heavy chain. That is, a Fab fragment is a monovalent antigen binding structure of an immunoglobulin without the Fc portion, and which results from the treatment of an immunoglobulin with papain.

[0110] The term "F(ab)' fragment" is defined as a fragment of an immunoglobulin molecule that comprises the variable regions of a light chain and a heavy chain. That is, the fragment is monovalent and most of the Fc portion is removed, which can be achieved through the treatment of an immunoglobulin molecule with pepsin and .beta.-mercaptoethanol.

[0111] The term "F(ab').sub.2 fragment" is defined as a fragment of an immunoglobulin molecule that comprises two F(ab) fragments and a portion of the hinge region. That is, most of the Fc portion is removed, which can be achieved through the treatment of an immunoglobulin molecule with pepsin.

[0112] The term "single-chain variable fragments" (scFvs) is defined as a polypeptide engineered to comprise the variable regions (i.e., the antigen-binding domains) of a light immunoglobulin chain and a heavy immunoglobulin chain. The light chain and heavy chain can be joined by a flexible linker sequence.

[0113] The term "monoclonal antibody" as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific, being directed against a single antigenic site. Furthermore, in contrast to conventional (polyclonal) antibody preparations that typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. The modifier "monoclonal" indicates the character of the antibody as being obtained from a substantially homogeneous population of antibodies, and is not to be construed as requiring production of the antibody by any particular method. For example, the monoclonal antibodies to be used in accordance with the present disclosure may be made by the hybridoma method first described by Kohler and Milstein 1975 Nature 256:495, or may be made by recombinant DNA methods. The "monoclonal antibodies" may also be isolated from phage antibody libraries.

[0114] The monoclonal antibodies herein specifically include "chimeric" antibodies (immunoglobulins) in which a portion of the heavy and/or light chain is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired biological activity.

[0115] "Humanized" forms of non-human (e.g., murine) antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulin. For the most part, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region of the recipient are replaced by residues from a hypervariable region of a non-human species (donor antibody) such as mouse, rat, rabbit or nonhuman primate having the desired specificity, affinity, and capacity. In some instances, Fv framework region (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, humanized antibodies may comprise residues that are not found in the recipient antibody or in the donor antibody. These modifications are made to further refine antibody performance. In general, the humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin sequence. The humanized antibody optionally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin.

[0116] The term "hypervariable region" when used herein refers to the amino acid residues of an antibody that are responsible for antigen-binding. The hypervariable region comprises amino acid residues from a "complementarity determining region" or "CDR" (i.e., residues 24-34 (L1), 50-56 (L2) and 89-97 (L3) in the light chain variable domain and 31-35 (H1), 50-65 (H2) and 95-102 (H3) in the heavy chain variable domain and/or those residues from a "hypervariable loop" (i.e., residues 26-32 (L1), 50-52 (L2) and 91-96 (L3) in the light chain variable domain and 26-32 (H1), 53-55 (H2) and 96-101 (H3) in the heavy chain variable domain). "Framework" or "FR" residues are those variable domain residues other than the hypervariable region residues as herein defined.

[0117] An "isolated" polypeptide is one that has been identified and separated and/or recovered from a component of its natural environment. Contaminant components of its natural environment are materials that would interfere with diagnostic or therapeutic uses for the polypeptide, and may include enzymes, hormones, and other proteinaceous or nonproteinaceous solutes. In preferred embodiments, the polypeptide will be purified (1) to greater than 95% by weight of polypeptide as determined by the Lowry method, and most preferably more than 99% by weight, (2) to a degree sufficient to obtain at least 15 residues of N-terminal or internal amino acid sequence by use of a spinning cup sequenator, or (3) to homogeneity by SDS-PAGE under reducing or non-reducing conditions using Coomassie blue or, preferably, silver stain. Isolated polypeptide includes the polypeptide in situ within recombinant cells since at least one component of the polypeptide's natural environment will not be present. Ordinarily, however, isolated polypeptides will be prepared by at least one purification step.

[0118] In an aspect, the disclosure provides a method of diagnosing a patient or subject with CD55 deficiency, hyperactivation of complement, angiopathic thrombosis and protein losing enteropathy (CHAPLE). The method comprises: providing a sample from a patient; performing an assay to detect at least one of: at least one mutation in a DNA sequence of a CD55 gene, at least one mutation in a RNA sequence of a CD55 transcript as compared to wild-type, at least one mutation in a DNA sequence of a CD55 complementary DNA (cDNA), decay-accelerating factor (DAF) or CD55 protein, complement deposition, or a combination thereof; and diagnosing the patient with CHAPLE. In an embodiment, the mutations in the DNA sequence of the CD55 gene or cDNA or the mutation in the RNA sequence of the CD55 RNA/transcript results in diminished CD55 protein expression (e.g., substantially diminished or devoice of CD55 expression) or diminished or non-functional CD55 protein function (e.g., a CD55 that has diminished or that is incapable of binding C3b and/or C4b).

[0119] In an embodiment, the patient is diagnosed with CHAPLE when at least one of the following is detected: (i) at least one mutation in a DNA sequence, an RNA sequence or a cDNA sequence of CD55 that results in a CD55 protein with substantially diminished functional activity, a CD55 protein with no functional activity, a lack of expression of CD55 protein (i.e., no CD55 protein expression), or a substantially diminished expression of CD55 protein; (ii) a CD55 protein with substantially diminished functional activity; (iii) a CD55 protein with no functional activity; (iv) a lack of expression of CD55 protein (i.e., no CD55 protein expression); (v) a substantially diminished expression of CD55 protein; or (vi) a combination thereof.

[0120] In another embodiment, the patient is diagnosed with CHAPLE when the patient has at least one CHAPLE related symptom and at least one of the following is detected: (i) at least one mutation in a DNA sequence, an RNA sequence or a cDNA sequence of CD55 that results in a CD55 protein with substantially diminished functional activity, a CD55 protein with no functional activity, a lack of expression of CD55 protein (i.e., no CD55 protein expression), or a substantially diminished expression of CD55 protein; (ii) a CD55 protein with substantially diminished functional activity; (iii) a CD55 protein with no functional activity; (iv) a lack of expression of CD55 protein (i.e., no CD55 protein expression); (v) a substantially diminished expression of CD55 protein; or (vi) a combination thereof.

[0121] The sample can be any sample that would contain genome DNA (gDNA) or that normally contains CD55 (i.e., a sample in which CD55 is found/expressed in an individual without CHAPLE). For example, the sample may be a blood sample, such as peripheral blood mononuclear cells (PBMC). Providing a sample can comprise at least one of: obtaining a sample from a patient (e.g., at least one PBMC), isolating gDNA from a patient sample, isolating (and/or purifying) protein from a patient sample or a combination thereof.

[0122] The CHAPLE associated symptom can include at least one of the following symptoms: inflammatory bowel disease, enteropathy, protein losing enteropathy, protein losing enteropathy associated with hypoalbuminemia, hypoalbuminemia, hypogammaglobulinemia, intestinal lymphangiectasia, lymphangiectasia, thrombotic events, thromboembolism, hyperactivation of complement, angiopathic thrombosis, hypoproteinemia, or a combination thereof. For example, the patient may have at least one, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, at least ten, at least eleven, at least twelve or all thirteen of the symptoms. In particular embodiments, the patient may have at least one of the following symptoms: inflammatory bowel disease, protein losing enteropathy associated with hypoalbuminemia, hypogammaglobulinemia, intestinal lymphangiectasia, thrombotic events or a combination thereof. For example, the patient can have at least two of the symptoms, at least three of the symptoms, at least four of the symptoms, or all five of the symptoms. That is, in certain embodiments, the patient has inflammatory bowel disease, protein losing enteropathy associated with hypoalbuminemia, hypogammaglobulinemia, intestinal lymphangiectasia, and thrombotic events.

[0123] The method can further comprise administering an effective amount of a composition of the present disclosure to the subject with CHAPLE, wherein the composition is effective in treating or preventing at least one symptom of CHAPLE. For example, the composition may comprise at least one complement inhibitor. The complement inhibitor can be selected from the group consisting of at least one serine protease inhibitor, at least one soluble complement regulator, at least one therapeutic antibody or antigen-binding fragment thereof, at least one complement component inhibitor, and at least one anaphylatoxin receptor antagonist.

[0124] In a further embodiment, the method further includes administering at least one additional agent selected from the group consisting of an anticoagulant or a thrombolytic agent, somatostatin analogues (e.g., octreotide), glucocorticoids, mesalizine, another immunosuppressive agent (e.g., TNF-.alpha. blocker), an albumin transfusion, intravenous immunoglobulins or a combination thereof. The additional agent can be included within the composition where appropriate or co-administered, as discussed above.

[0125] In an embodiment, the method of diagnosing a patient with CHAPLE can further comprise confirming the diagnosis by administering the composition of the present disclosure, thereby treating at least one symptom of CHAPLE (i.e., a CHAPLE related symptom) or preventing the reoccurrence of at least one symptom of CHAPLE.

[0126] The mutation of the present disclosure, i.e., mutations in the DNA sequence of the CD55 gene (which can be determined or detected by a mutation in the RNA sequence of the CD55 transcript (e.g., mRNA) or the DNA sequence of CD55 cDNA), can result in a near to complete absence of CD55 protein expression or the expression of CD55 protein with substantially diminished function or that is non-functional. That is, the mutant CD55 protein can have diminished (or decreased) function relative to wild-type CD55. For example, mutant CD55 may bind C4b and/or C3b with lesser (or decreased) affinity and/or avidity, or not at all. In certain embodiments, CD55 is not present or substantially not present in patients with CHAPLE syndrome/disease.

[0127] As discussed above, the mutation in the DNA sequence of the CD55 gene (and therefore, the RNA sequence of the transcript and the DNA sequence of the cDNA of the CD55 gene) can be any mutation that results in: (i) the expression of CD55 protein with decreased function relative to wild-type CD55 (e.g., CD55 protein with substantially no ability to bind C3b and/or C4b); and/or (ii) a decreased amount of CD55 expression relative to wild-type CD55 (e.g., no expression of CD 55 protein). For example, the mutation in the DNA sequence of the CD55 gene (which one skilled in the art would appreciate that these mutations can be detected in the RNA and DNA sequences of CD55 transcripts and cDNA, respectively) can be at least one of c.149-150delAA, c.149-150insCCTT, c.109delC, c.800G>C, c.287-1G>C, c.149-150delAAinsCCTT or a combination thereof. That is, in an embodiment, the DNA sequence of the CD55 gene has at least one, at least two, at least three, or all four of the above-mentioned mutations in the DNA sequence of the CD55 gene, or the related transcript or cDNA.

[0128] In further embodiments, detecting can include at least one of: (i) sequencing at least a portion of the CD55 gene or the CD55 transcript or the CD55 cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA); or (ii) contacting a labeled nucleic acid probe (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more probes) to at least a portion of the CD55 gene or the CD55 transcript or the CD55 cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA); or (iii) contacting at least a portion of the CD55 gene or CD55 transcripts or the CD55 cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA) with a microarray; or (iv) a combination thereof.

[0129] Hybridization of the labeled nucleic acid probe brought into contact with CD55 gDNA, RNA transcripts, or cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA) from the patient's sample can be indicative of a mutation in the portion of the CD55 gene or CD55 transcript or the CD55 cDNA. Alternatively, hybridization of the labeled nucleic acid probe that was brought into contact with CD55 gDNA, RNA transcripts, or cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA) from the patient's sample can be indicative of the portion of the CD55 gene or CD55 transcript or the CD55 cDNA having a wild-type sequence at (or lacking CD55 associated mutations in the portion hybridized) the location of hybridization.

[0130] Sequencing at least a portion of the CD55 gene (or the CD55 transcript or CD55 cDNA that is produced from the CD55 transcripts) can include amplifying at least one region of interest for sequencing. The region of interest for sequencing can include any coding sequence (exon) of the CD55 gene or any CD55 exon and portions that flank the exons. For example, in a particular embodiment, at least one polymerase chain reaction (PCR) is performed with at least one of the following primer sets to produce amplicons of the CD55 gene, mRNA (e.g., transcripts), and/or cDNA: (i) CTACTCCACCCGTCTTGTTTGT and TTTGGGGGTTAAGGATACAGTC (Exon 1); (ii) CAGGTGTGGCATTTCAAGG and ACCCTGGGGTTTAGTAACGC (Exon 2); (iii) AAGTACTAAATATGCGCAAAGCAG and ATGGTCCTATCAAGAAACATCC (Exon 3); (iv) GTTACCTTCTTTGTGTGTATGCC and GCTGTGAATACCAGTCATGAAAC (Exon 4); (v) AACCTGGAGAATTTGAGGAAAG and TGTGCTAATATTCTTAAGGGGC (Exon 5); (vi) GCATTTATAAGCATCTCTTGTTGG and TCATTGAATGTCTGCAACCC (Exon 6); (vii) CTAGGTGTTTGTGGGGAGAGAG and TCTGGTGGGTTTCTGAAGAGTT (Exon 7); (viii) TTTACGCAGAGTCCTTCAGC and CCATTTAATCCTGCAATCTTGG (Exon 8); (ix) TGGAAATTTGAGTTGCTTTCG and TCTCCCAGGAATATGGATTG (Exon 9); (x) GCACCCCAAATTAACTGATTC and ATGTGATTCCAGGACTGCC (Exon 10); or (xi) a combination thereof.

[0131] Contacting a labeled nucleic acid probe to at least a portion of the CD55 gene (or the CD55 transcript or the CD55 cDNA produced from the CD55 transcript, or amplicons produced from the CD55 gene, transcript, or cDNA) can be performed or accomplished with real-time PCR. Hybridization of a real-time PCR probe can be indicative of a mutation in the portion of the CD55 gene or CD55 transcript or CD55 cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA). Alternatively, hybridization of a real-time PCR probe can be indicative of the portion of the CD55 gene or CD55 transcript or CD55 cDNA (or amplicons produced from the CD55 gene, transcript, or cDNA) having a wild-type sequence at the location of hybridization (or amplicons produced from the CD55 gene, transcript, or cDNA). Furthermore, contacting a labeled nucleic acid probe to at least a portion of the CD55 cDNA (or amplicons produced from the CD55 transcripts or cDNA) may comprise: isolating CD55 transcripts; reverse transcribing at least a portion of the CD55 transcripts; and contacting the cDNA with the labeled nucleic acid probe. This may further comprise amplifying a portion or region of interest via PCR (see discussion above) prior to contacting the amplicons produced from CD55 cDNA with the labeled nucleic acid probe.

[0132] The microarray can include probes (e.g., immobilized probes) designed or configured to detect or bind CD55 gene (i.e., the sense and/or antisense DNA stand(s)), transcripts (i.e., mRNA), or cDNA sequence (or amplicons produced from the CD55 gene, transcript, or cDNA) of a patient with at least one mutation that result in the complete absence in CD55 protein or a CD55 protein with substantially diminished or devoid of function, as described above. Alternatively, the microarray can include probes (e.g., immobilized probes) designed or configured to detect or bind a wild-type CD55 DNA, transcript (i.e., RNA), or cDNA sequence (or amplicons produced from the CD55 gene, transcript, or cDNA) of a patient or subject. In a further embodiment, the microarray may include probes designed or configured to individually detect (i.e., separately detect) both CD55 mutations and wild-type CD55.

[0133] As used herein, the terms "probe(s)" and "primer(s)" refers to oligonucleotide sequences that may readily be prepared based on the CD55 nucleic acids described herein. A probe may comprise an isolated nucleic acid attached to a detectable label or reporter molecule. In any aspect or embodiment described herein, the detectable label or label is selected from the group consisting of an enzyme, a chemiluminescent agent, a ligand, biotin, streptavidin, a radioactive molecule, and an immunofluorescent protein or dye. Methods for labeling and guidance in the choice of labels appropriate for various purposes are discussed, e.g., in Sambrook et al. (1989) and Ausubel et al. (1987). "Primers" are short nucleic acids, such as DNA oligonucleotides 15 nucleotides or more in length (e.g., 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleotides in length). Primers may be annealed to a complementary target DNA strand by nucleic acid hybridization to form a hybrid between the primer and the target DNA strand, and then extended along the target DNA strand by a DNA polymerase enzyme. Primer pairs can be used for amplification of a nucleic acid sequence, e.g., by the polymerase chain reaction (PCR) or other nucleic-acid amplification methods known in the art.

[0134] Methods for preparing and using probes and primers are described, for example, in Sambrook et al. (1989), Ausubel et al. (1987), and Innis et al., (1990). PCR primer pairs can be derived from a known sequence, for example, by using computer programs intended for that purpose such as Primer (Version 0.5, 1991, Whitehead Institute for Biomedical Research, Cambridge, Mass.). One of skill in the art will appreciate that the specificity of a particular probe or primer increases with its length. Thus, for example, a primer comprising 20 consecutive nucleotides of the human CD55 cDNA, RNA, or gene will anneal to a-target sequence such as a CD55 gene within a genomic DNA sample with a higher specificity than a corresponding primer of only 15 nucleotides. Thus, in order to obtain greater specificity, probes and primers may be selected that comprise 20, 25, 30, 35, 40, 50 or more consecutive nucleotides that are complementary to the nucleotide sequence at the site of a mutation as described herein or the wild-type sequence at the same location.

[0135] Thus, the probe or probes of the present disclosure can include a nucleic acid sequence that is complementary (e.g., hybridizes under stringent conditions) to the site of a mutation as described herein or the wild-type nucleic acid sequence at the same location. The probe can include complementary bases 5' and 3' of the site of mutation. For example, the probe includes complementary bases 5' of the site of mutation by at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 45, 46, 47, 48, 49, or 50 nucleotides (e.g., the probe include complementary bases 5' of the site of mutation by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 45, 46, 47, 48, 49, or 50 nucleotides). For example, the probe includes complementary bases 3' of the site of mutation by at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 45, 46, 47, 48, 49, or 50 nucleotides (e.g., the probe include complementary bases 3' of the site of mutation by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 45, 46, 47, 48, 49, or 50 nucleotides). As described above, in certain embodiments, the probe is complementary to the wild-type sequence, wherein no hybridization is indicative of a mutation and/or hybridization is indicative of no mutation. In other embodiments, the probe is complementary to a mutation as described herein, wherein hydridization is indicative of a mutation and/or no hybridization is indicative of no mutation. As described above, the probe can be complementary to the mRNA, the DNA sense strand, the DNA antisense strand, and/or cDNA.

[0136] In any aspect or embodiments described herein, the nucleic acid probes and/or primes of the disclosure hybridize specifically to target polynucleotides of interest (i.e., a wild-type nucleic acid sequence or a mutation containing nucleic acid sequence as described herein) under stringent conditions. Two molecules hybridizing to each other under stringent conditions is an indication that the two nucleic acid sequences are substantially identical. Stringent conditions are sequence dependent and different under different environmental parameters and for different assays. As used herein, "stringent conditions" or "stringent hybridization conditions" means any conditions in which hybridization will occur when there is at least about 95%, at least 96%, at least 97%, at feat 98%, or at least 99% nucleotide complementarity or identity (e.g., about 95% to about 100% or about 97 to about 100%, such as about 95%. about 96%. about 97%, about 98%, about 99%, or about 100%) between the nucleic acids (e.g., a polynucleotide of interest and a nucleic acid probe). For example, stringent conditions for may be selected to be about 5.degree. C. to 20.degree. C. lower than the thermal melting point (T.sub.m) the specific sequence at a defined ionic strength and pH. The T.sub.m is the temperature (under defined ionic strength and pH) at which 50% of the target sequence hybridizes to a perfectly matched probe. Conditions for nucleic acid hybridization and calculation of stringencies can be found in Sambrook et al. (1989) and Tijssen (1993) and are otherwise known in the art.

[0137] For example, appropriate high stringent hybridization conditions for microarray may include, e.g., hybridization in a buffer, such as 6.times.SSPE-T (0.9 M NaCl, 60 mM NaH.sub.2PO.sub.4, 6 mM EDTA and 0.05% Triton X-100) for between about 10 minutes and about at least 3 hours (e.g., at least about 15 minutes) at a temperature ranging from about 4.degree. C. to about 37.degree. C. In an embodiment, hybridization under high stringent conditions is carried out in 5.times.SSC, 50% dionized Formamide, 0.1% SDS at 42.degree. C. overnight.

[0138] Hybridization specificity can be evaluated by comparing the hybridization of specificity-control nucleic acid probes to specificity-control target polynucleotides that are added to a sample in a known amount. The specificity-control target polynucleotides may have one or more sequence mismatches compared with the corresponding nucleic acid probes. In this manner, whether only complementary target polynucleotides are hybridizing to the nucleic acid probes or whether mismatched hybrid duplexes are forming is determined.

[0139] Hybridization reactions can be performed in absolute or differential hybridization formats. In the absolute hybridization format, target polynucleotides from one sample are hybridized to the probes in an array (e.g., in a microarray format) and signals detected after hybridization complex formation correlate to target polynucleotide levels in a sample. In the differential hybridization format, the differential expression of a set of genes in two biological samples is analyzed. For differential hybridization, target polynucleotides from both biological samples are prepared and labeled with different labeling moieties. A mixture of the two labeled target polynucleotides is added to an array (e.g., a microarray). The array is then examined under conditions in which the emissions from the two different labels are individually detectable. Probes in the array that are hybridized to substantially equal numbers of target polynucleotides derived from both biological samples give a distinct combined fluorescence (Shalon et al. PCT publication WO95/35505). In a preferred embodiment, the labels are fluorescent labels with distinguishable emission spectra.

[0140] After hybridization, the array (e.g., microarray) is washed to remove nonhybridized polynucleotides and complex formation between the hybridizable array elements and the target polynucleotides is detected. Methods for detecting complex formation are well known to those skilled in the art. In a preferred embodiment, the target polynucleotides are labeled with a fluorescent label and levels and patterns of fluorescence indicative of complex formation are measured. In one embodiment, the measurement is accomplished by fluorescence microscopy, preferably confocal fluorescence microscopy. An argon ion laser excites the fluorescent label, emissions are directed to a photomultiplier and the amount of emitted light detected and quantitated. The detected signal should be proportional to the amount of probe/target polynucleotide complex at each position of the microarray. The fluorescence microscope can be associated with a computer-driven scanner device to generate a quantitative two-dimensional image of hybridization intensity. The scanned image is examined to determine the abundance/expression level of each hybridized target polynucleotide. In another embodiment, the measurement of levels and patterns of fluorescence is accomplished with a fluorescent imaging device, such as a microarray scanner (e.g., Axon scanner with GenePix Pro software). As with the previous measurement method, the measurements can be used to determine the abundance/expression level of each hybridized target polynucleotide, thereby determining whether there is a mutation as described herein and/or the expression level of CD55 dependening upon the technique utilized.

[0141] Detecting CD55 protein can be performed via any known protein detection technique, e.g., western blot, flow cytometry, an immunoassay, microscopy, protein immunostaining, immunoelectrophoresis, spectrophotometry, etc. For example, detecting CD55 protein can comprise: contacting the sample with at least one CD55 binding polypeptide. The CD55-binding polypeptide can be an anti-CD55 antibody or a CD55-binding fragment thereof. The CD55-binding polypeptide may be used in any assay that can detect either a wild-type CD55 protein or a mutant CD55 protein that has substantially diminished functional activity, for example, the CD55 has decreased or no binding activity for C3b and/or C4b (discussed in greater detail above), or both. The CD55 binding polypeptides can include a detectable label. For example, the labelled CD55 binding polypeptide can include a fluorescent label or an enzyme, which facilitates the detection of the CD55 protein (mutant and/or wild-type, as discussed above) via flow cytometry or ELISA/western blot, respectively. One skilled in the art would appreciate that the CD55-binding polypeptide may be utilized in numerous other techniques, e.g., see above and below, to detect mutant CD55 protein, wild-type CD55 protein, or both mutant and wild-type CD55 protein.

[0142] Detecting CD55 protein can further comprise contacting the sample or a CD55-CD55-binding polypeptide complex with at least one secondary polypeptide that binds specifically to the CD55 binding polypeptide. The secondary polypeptide can include a detectable label. The secondary polypeptide can be an antibody or fragment thereof that binds the CD55 binding polypeptide. For example, the labelled secondary polypeptide can include a fluorescent label or an enzyme, which facilitates the detection of the CD55 protein (mutant and/or wild-type, as discussed herein) via flow cytometry or ELISA/western blot, respectively.

[0143] The present disclosure contemplates the use of any suitable detection assay, which is known or becomes known to those skilled in the art. As would be appreciated by the skilled artisan in view of the present disclosure, any particular detection assay could be employed with no more than routine experimentation. In certain embodiments, the step of detecting CD55 protein is performed using at least one of a western blot, flow cytometry, an immunoassay, or a combination thereof. For example, the immunoassay can be at least one assay selected from the group consisting of enzyme-linked immunosorbent assay (ELISA), flow cytometry, radioimmunoassay, magnetic immunoassay, enzyme-linked immunospot (ELISPOT), and immunofluorescence. For example, detecting CD55 protein can be performed using a western blot of protein isolated from (e.g., a crude or purified protein isolate) the patient sample (e.g., PBMCs) or flow cytometry performed on, e.g., PBMCs, in which CD55 is detected with a CD55-binding polypeptide, which includes a detectable label (or marker) or via at least one secondary polypeptide that includes a detectable label (or marker). Alternatively, a sandwich (or capture) ELISA could be utilized, in which the PBMCs are captured by, e.g., an antibody known to bind the surface of a PBMC (or a CD55 binding protein) thereby capturing the PBMCs, and detecting CD55 protein through the binding of a CD55-binding polypeptide. The CD55-binding polypeptide can include a detectable label or a secondary polypeptide with a detectable label may be used, as discussed herein.

[0144] In another embodiment, the detecting of CD55 binding function includes examining at least one of C3b affinity, C3b avidity, C4b affinity, C4b avidity or a combination thereof. That is, CD55 binding to C3b and/or C4b may be assessed by determining the affinity and/or avidity of the CD55-C3b or CD55-C4b interaction/binding. Examination of this function interaction (e.g., affinity and/or avidity) can be performed by methods well-known in the art with routine experimentation for one skilled in the art.

[0145] In a particular embodiment, detecting complement deposition includes detecting C3d deposition. For example, the patient sample (e.g., PBMCs) may be contacted with a C3d binding polypeptide. The Cd3 bound Cd3 binding polypeptide can include a detectable label (or marker) or the complex may be detected with a secondary polypeptide that is specific for the Cd3 binding polypeptides and has a detectable label. As such, Cd3 may be detected by any of the methods articulated for detecting CD55, such as flow cytometry or ELISA.

[0174] The pharmaceutical compositions as described herein may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers which are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

[0175] Alternatively, the pharmaceutical compositions as described herein may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient, which is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.

[0176] The pharmaceutical compositions as described herein may also be administered topically. Suitable topical formulations are readily prepared for each of these areas or organs. Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically-acceptable transdermal patches may also be used.

[0177] For topical applications, the pharmaceutical compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of the compounds of this disclosure include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. In certain preferred aspects of the disclosure, the compounds may be coated onto a stent which is to be surgically implanted into a patient in order to inhibit or reduce the likelihood of occlusion occurring in the stent in the patient.

[0178] Alternatively, the pharmaceutical compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

[0179] For ophthalmic use, the pharmaceutical compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with our without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutical compositions may be formulated in an ointment such as petrolatum.

[0180] The pharmaceutical compositions as described herein may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.

[0181] The amount of compound in a pharmaceutical composition as described herein that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host and disease treated, the particular mode of administration. Preferably, the compositions should be formulated to contain between about 0.05 milligram to about 750 milligrams or more, more preferably about 1 milligram to about 600 milligrams, and even more preferably about 10 milligrams to about 500 milligrams of active ingredient, alone or in combination with at least one other compound according to the present disclosure.

[0182] It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease or condition being treated.

[0183] A patient or subject in need of therapy using compounds according to the methods described herein can be treated by administering to the patient (subject) an effective amount of the compound according to the present disclosure including pharmaceutically acceptable salts, solvates or polymorphs, thereof optionally in a pharmaceutically acceptable carrier or diluent, either alone, or in combination with other agents as otherwise identified herein.

[0184] These compounds can be administered by any appropriate route, for example, orally, parenterally, intravenously, intradermally, subcutaneously, or topically, including transdermally, in liquid, cream, gel, or solid form, or by aerosol form.

[0185] The active compound is included in the pharmaceutically acceptable carrier or diluent in an amount sufficient to deliver to a patient a therapeutically effective amount for the desired indication, without causing serious toxic effects in the patient treated. A preferred dose of the active compound for all of the herein-mentioned conditions is in the range from about 10 ng/kg to 300 mg/kg, preferably 0.1 to 100 mg/kg per day, more generally 0.5 to about 25 mg per kilogram body weight of the recipient/patient per day. A typical topical dosage will range from 0.01-5% wt/wt in a suitable carrier.

[0186] The compound is conveniently administered in any suitable unit dosage form, including but not limited to one containing less than 1 mg, 1 mg to 3000 mg, preferably 5 to 500 mg of active ingredient per unit dosage form. An oral dosage of about 25-250 mg is often convenient.

[0187] The active ingredient is preferably administered to achieve peak plasma concentrations of the active compound of about 0.00001-30 mM, preferably about 0.1-30 .mu.M. This may be achieved, for example, by the intravenous injection of a solution or formulation of the active ingredient, optionally in saline, or an aqueous medium or administered as a bolus of the active ingredient. Oral administration is also appropriate to generate effective plasma concentrations of active agent.

[0188] The concentration of the active compound in the drug composition will depend on absorption, distribution, inactivation, and excretion rates of the drug as well as other factors known to those of skill in the art. It is to be noted that dosage values will also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed composition. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at varying intervals of time.

[0189] Oral compositions will generally include an inert diluent or an edible carrier. They may be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound or its prodrug derivative can be incorporated with excipients and used in the form of tablets, troches, or capsules. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition.

[0190] The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a dispersing agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. When the dosage unit form is a capsule, it can contain, in addition to material of the above type, a liquid carrier such as a fatty oil. In addition, dosage unit forms can contain various other materials which modify the physical form of the dosage unit, for example, coatings of sugar, shellac, or enteric agents.

[0191] The active compound or pharmaceutically acceptable salt thereof can be administered as a component of an elixir, suspension, syrup, wafer, chewing gum or the like. A syrup may contain, in addition to the active compounds, sucrose as a sweetening agent and certain preservatives, dyes and colorings and flavors.

[0192] The active compound or pharmaceutically acceptable salts thereof can also be mixed with other active materials that do not impair the desired action, or with materials that supplement the desired action. In certain preferred aspects of the disclosure, one or more compounds according to the present disclosure are coadministered with another bioactive agent including an antibiotic, as otherwise described herein.

[0193] Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerin, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. The parental preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

[0194] If administered intravenously, preferred carriers are physiological saline or phosphate buffered saline (PBS).

[0195] In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art.

[0196] Liposomal suspensions may also be pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811 (which is incorporated herein by reference in its entirety). For example, liposome formulations may be prepared by dissolving appropriate lipid(s) (such as stearoyl phosphatidyl ethanolamine, stearoyl phosphatidyl choline, arachadoyl phosphatidyl choline, and cholesterol) in an inorganic solvent that is then evaporated, leaving behind a thin film of dried lipid on the surface of the container. An aqueous solution of the active compound is then introduced into the container. The container is then swirled by hand to free lipid material from the sides of the container and to disperse lipid aggregates, thereby forming the liposomal suspension.

[0197] The present disclosure also includes pharmaceutically acceptable formulations of the compounds described. These formulations include salts of the above compounds, e.g., acid addition salts, for example, salts of hydrochloric, hydrobromic, acetic acid, and benzene sulfonic acid.

[0198] A pharmacological composition or formulation refers to a composition or formulation in a form suitable for administration, e.g., systemic administration, into a cell or subject, preferably a human. By "systemic administration" is meant in vivo systemic absorption or accumulation of drugs in the blood stream followed by distribution throughout the entire body. Suitable forms, in part, depend upon the use or the route of entry, for example oral, transdermal, or by injection. Such forms should not prevent the composition or formulation from reaching a target cell (i.e., a cell to which the negatively charged polymer is desired to be delivered to). For example, pharmacological compositions injected into the blood stream should be soluble. Other factors are known in the art, and include considerations such as toxicity and forms which prevent the composition or formulation from exerting its effect.

[0199] Administration routes which lead to systemic absorption include, without limitations: intravenous, subcutaneous, intraperitoneal, inhalation, oral, intrapulmonary and intramuscular. The rate of entry of a drug into the circulation has been shown to be a function of molecular weight or size. The use of a liposome or other drug carrier comprising the compounds of the present disclosure can potentially localize the drug, for example, in certain tissue types, such as the tissues of the reticular endothelial system (RES). A liposome formulation which can facilitate the association of drug with the surface of cells, such as, lymphocytes and macrophages is also useful.

[0200] The present disclosure also features the use of the composition comprising surface-modified liposomes containing poly (ethylene glycol) lipids (PEG-modified, or long-circulating liposomes or stealth liposomes). Polypeptides and compositions of the present disclosure can also comprise covalently attached PEG molecules of various molecular weights. These formulations offer a method for increasing the accumulation of drugs in target tissues. This class of drug carriers resists opsonization and elimination by the mononuclear phagocytic system (MPS or RES), thereby enabling longer blood circulation times and enhanced tissue exposure for the encapsulated drug (Lasic et al. Chem. Rev. 1995, 95, 2601-2627; Ishiwata et al., Chem. Pharm. Bull. 1995, 43, 1005-1011). Long-circulating liposomes are also likely to protect drugs from nuclease degradation to a greater extent compared to cationic liposomes, based on their ability to avoid accumulation in metabolically aggressive MPS tissues such as the liver and spleen. All of these references are incorporated by reference herein.

[0201] The present disclosure also includes compositions prepared for storage or administration which include a pharmaceutically effective amount of the desired compounds (e.g., agents and/or complement inhibitors) in a pharmaceutically acceptable carrier or diluent. Acceptable carriers or diluents for therapeutic use are well known in the pharmaceutical art, and are described, for example, in Remington's Pharmaceutical Sciences, Mack Publishing Co. (A. R. Gennaro edit. 1985) hereby incorporated by reference herein. For example, preservatives, stabilizers, dyes and flavoring agents can be provided. These include sodium benzoate, sorbic acid and esters of p-hydroxybenzoic acid. In addition, antioxidants and suspending agents can be used.

[0202] An effective amount, pharmaceutically effective dose, therapeutically effective amount, or pharmaceutically effective amount is that dose required to prevent, inhibit the occurrence, or treat (alleviate a symptom to some extent, preferably all of the symptoms) of a disease state or pathological condition. The effective amount depends on the type of disease, the composition used, the route of administration, the type of mammal being treated, the physical characteristics of the specific mammal under consideration, concurrent medication, and other factors which those skilled in the medical arts will recognize. Generally, an amount between 0.1 mg/kg and 1000 mg/kg body weight/day of active ingredients is administered dependent upon potency of the negatively charged polymer. In addition, effective amounts of the compositions of the disclosure encompass those amounts utilized in the examples to facilitate the intended or desired biological effect.

[0203] Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD50/ED50. Compounds (e.g., agents and/or complement inhibitors) that exhibit large therapeutic indices are preferred. While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects. The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the present disclosure, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography.

[0204] The formulations can be administered orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes percutaneous, subcutaneous, intravascular (e.g., intravenous), intramuscular, or intrathecal injection or infusion techniques and the like. In addition, there is provided a pharmaceutical formulation comprising at least two agents, wherein at least one is a complement inhibitor, and a pharmaceutically acceptable carrier. For example, two or more complement inhibitors can be present in association with one or more non-toxic pharmaceutically acceptable carriers and/or diluents and/or adjuvants, and if desired other active ingredients. The pharmaceutical compositions of the present disclosure can be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsion, hard or soft capsules, or syrups or elixirs.

[0205] Compositions intended for oral use can be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions can contain one or more such sweetening agents, flavoring agents, coloring agents or preservative agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients that are suitable for the manufacture of tablets. These excipients can be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets can be uncoated or they can be coated by known techniques. In some cases such coatings can be prepared by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monosterate or glyceryl distearate can be employed. Formulations for oral use can also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin or olive oil.

[0206] Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydropropyl-methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents can be a naturally-occurring phosphatide, for example, lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions can also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

[0207] Oily suspensions can be formulated by suspending the active ingredients in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions can contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents and flavoring agents can be added to provide palatable oral preparations. These compositions can be preserved by the addition of an anti-oxidant such as ascorbic acid.

[0208] Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, can also be present. Pharmaceutical compositions of the present disclosure can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents can be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions can also contain sweetening and flavoring agents.

[0209] Syrups and elixirs can be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations can also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions can be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension can be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

[0210] For administration to non-human animals, the composition can also be added to the animal feed or drinking water. It can be convenient to formulate the animal feed and drinking water compositions so that the animal takes in a therapeutically appropriate quantity of the composition along with its diet. It can also be convenient to present the composition as a premix for addition to the feed or drinking water. The composition can also be administered to a subject in combination with other therapeutic compounds to increase the overall therapeutic effect. The use of multiple compounds to treat an indication can increase the beneficial effects while reducing the presence of side effects.

[0211] A further object of the present disclosure is to provide a kit comprising a suitable container, the therapeutic of the present disclosure in a pharmaceutically acceptable form disposed therein, and instructions for its use.

[0212] Preparations for administration of the therapeutic of the present disclosure include sterile aqueous or non-aqueous solutions, suspensions, and emulsions. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. Vehicles include sodium chloride solution, Ringer's dextrose, dextrose and sodium chloride, lactated Ringer's intravenous vehicles including fluid and nutrient replenishers, electrolyte replenishers, and the like. Preservatives and other additives may be added such as, for example, antimicrobial agents, anti-oxidants, chelating agents and inert gases and the like.

[0213] The compounds or peptides (e.g., agent, agents, and/or complement inhibitors; also referred to herein as "active compounds") of the disclosure, and derivatives, fragments, analogs and homologs thereof, can be incorporated into pharmaceutical compositions suitable for administration. Such compositions typically comprise the compound or protein and a pharmaceutically acceptable carrier. As used herein, "pharmaceutically acceptable carrier" is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Suitable carriers are described in the most recent edition of Remington's Pharmaceutical Sciences, a standard reference text in the field, which is incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, finger's solutions, dextrose solution, and 5% human serum albumin. Liposomes and non-aqueous vehicles such as fixed oils may also be used. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds can also be incorporated into the compositions.

[0214] A pharmaceutical composition of the present disclosure is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), transdermal (i.e., topical), transmucosal, intraperitoneal, and rectal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid (EDTA); buffers such as acetates, citrates or phosphates, and agents for the adjustment of tonicity such as sodium chloride or dextrose. The pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.

[0215] Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor.TM.. (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringeability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

[0216] For oral administration, the pharmaceutical compositions may take the form of, for example, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulphate). The tablets may be coated by methods well known in the art. Liquid preparations for oral administration may take the form of, for example, solutions, syrups, or suspensions, or they may be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The preparations may also contain buffer salts, flavoring, coloring, and sweetening agents as appropriate. Preparations for oral administration may be suitably formulated to give controlled release of the active compound. For buccal administration the compositions may take the form of tablets or lozenges formulated in conventional manner. For administration by inhalation, the compounds for use according to the present disclosure are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of e.g. gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch. The compounds may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing, and/or dispersing agents. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use. The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides. In addition to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

[0217] In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811.

[0218] It is especially advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the disclosure are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals.

[0219] Additional objects and advantages of the present disclosure will be appreciated by one of ordinary skill in the art in light of the current description and examples of the preferred embodiments, and are expressly included within the scope of the present disclosure.

[0228] Genomic DNA (gDNA) was obtained from probands and family members by isolation and purification from peripheral blood mononuclear cells (PBMCs) using DNeasy.RTM. Blood and Tissue Kit (QIAGEN.RTM., Hilden, Germany). DNA was then submitted for Whole Exome Sequencing (WES) or targeting sequencing of the CD55 gene. For whole exome sequencing, the Human All Exon 50 Mb kit (Agilent Technologies, Santa Clara, Calif., USA) coupled with massively parallel sequencing by Illumina.RTM. HiSeg.TM. Sequencing System (IIlumina, Inc., San Diego, Calif., USA) was performed using the collected DNA. For individual samples, WES produced approximately 50-100.times. sequence coverage for targeted regions. WES was performed on patients 1.1, 2.1 along with 3.1 and 5.1 in which WES was combined with homozygosity mapping. As described previously, all sequenced DNA reads were mapped to the hg19 human genome reference by Burrows-Wheeler Aligner with default parameters. Single nucleotide variant and indel calling were performed using the Genome Analysis Toolkit (Broad Institute, Cambridge, Mass., USA). All SNVs/indels were annotated by SeattleSeq Annotation and an in-house custom analysis pipeline was used to filter and prioritize for autosomal recessive or de novo disease-causal variants based on the clinical pedigree for Patients 1.1 and 2.1, the mutations were identified by targeted gene screening of the WES data based on the similarity of clinical phenotype in the cohort (Lucas C L, et al. Heterozygous splice mutation in PIK3R1 causes human immunodeficiency with lymphoproliferation due to dominant activation of PI3K. J Exp Med 2014; 211: 2537-47).

[0229] For targeted sequencing, CD55/DAF exons 1 through 10 were PCR amplified, purified, or gel extracted using QIAGEN's MinElute.RTM. PCR Purification Kit (QIAGEN.RTM., Hilden, Germany) or QIAquick.RTM. Gel Extraction Kit (QIAGEN.RTM., Hilden, Germany), respectively. Samples were submitted to the National Institute of Allergy and Infectious Disease Research Technologies Branch Core Sequencing facility for Sanger sequencing. DNA sequences were analyzed using SEQUENCHER.RTM. V.5.3 (Gene Codes Corporation, Ann Arbor, Mich., USA). The primers used for Sanger sequencing and the amplicons produced therefrom are shown in Table 1, below.

[0236] Flow Cytometry. Adherent cells were treated with 0.05% trypsin EDTA to lift them from the surface followed by addition of 5% FBS to inactivate the trypsin. Suspension cells were collected from culture following mixture of the culture by repeat pipetting. Cells were washed and resuspended in FACS buffer (1% FBS, 0.05% sodium azide, and 5 mM EDTA in PBS) at 2.times.10.sup.6 cells/mL. Staining or isotype antibodies were added at 1:200 final dilutions and incubated with cells at 4.degree. C. for 30 minutes to 1 hour. Cells were then washed 3.times. and resuspended in FACS buffer with 1% PFA and analyzed by flow cytometry. Flow files were analyzed on FlowJo version 9.9 or above (FlowJo, LLC, Ashland, Oreg., USA).

[0237] Complement Deposition.

[0238] T cells (Patient CD4.sup.+ T cell blasts or Jurkat T cells) were collected and washed 3.times. in basal RPMI. Cells were then resuspended in basal media and rested for 2-3 hours at 37.degree. C. to allow any deposited complement components to be cleared from the cell surface. Rested cells were then collected and resuspended in basal RPMI or basal RPMI that had been adjusted to pH 6.5 (acidified media) to a final concentration of 1.times.10.sup.6 cells/mL. Non-heat shocked pooled normal human serum was then added to cell suspension for the indicated amount of time. Human serum that had been heat shocked at 56.degree. C. for 30 minutes was used as a negative control for complement activation. At the indicated times cells were transitioned to 4.degree. C., and kept chilled for the remainder of the experiment. Cells were stained with a 1:300 dilution of anti-C3d antibody for 30 minutes, washed 3.times. and then stained with an anti-rat antibody conjugated with alexa fluor 488 at a 1:500 dilution for 30 minutes. Cells were washed 3.times. and resuspended in FACS buffer (PBS, 1% FBS) and analyzed for C3d deposition by flow cytometry. To analyze C3d deposition on HT29 cells, cells were either left untreated or treated overnight with 10 ng/mL TNF.alpha. to upregulate CD55 expression. Cells were then treated with trypsin/EDTA to release cells into suspension, washed, and then analyzed for C3d deposition as above.

[0239] Preparation of T cell Stimulatory Surfaces.

[0240] Tissue culture treated 48, or 96 well plates were incubated with the indicated concentration of anti-CD3 in PBS for 2 hours at 37.degree. C. Plates were then washed 3.times. in PBS and incubated with either anti-CD28, anti-CD55, or CD97fc for 2 hours at 37.degree. C. Plates were again washed 3.times. with PBS before using in T cell stimulations.

[0241] T cell Stimulation and Cytokine Secretion.

[0242] To measure T cell activation isolated CD4 T cells were either left alone or stained with 1 .mu.M CFSE for 5 minutes at room temperature, protected from light. Labelled cells were washed 3.times. in complete RPMI prior to use and resuspended at 1.times.10.sup.6 cells/mL in complete RPMI. Cells were then added to stimulatory surfaces, pre-coated with the indicated concentrations of activating antibodies/proteins. To measure CD25 and CD69 upregulation, non-CFSE labeled T cells were collected after 24 hours and analyzed by flow cytometry for CD25 and CD69 expression, as detailed above. To assess T cell proliferation, CFSE labeled T cell cultures were collected after 96 hours of stimulation and analyzed by flow cytometry for CFSE dilution.

[0243] For cytokine secretion upon primary stimulation, Naive CD4.sup.+ T cells were isolated via negative selection using the Naive CD4.sup.+ T Cell Isolation Kit II, human isolation kit (Miltenyi Biotec Inc., Auburn, Calif., USA). Naive T cells were then resuspended in complete X-Vivo 15 media. Dynabeads.RTM. CD3/CD28 T cell activator (Invitrogen.TM., Carlsbad, Calif., USA) were then added to cells (1 bead/2 cells) and cells and dynabeads were centrifuged at 300.times.g for 5 minutes to complex beads and T cells. Cells were resuspended and added to 48 well plates at a final concentration of 5.times.10.sup.4/mL in complete X-vivo 15 media. Cell culture supernatants were collected every 24 hours starting at 96 hours post-activation for the indicated time course. Cell cultures were stored at .sup.-80.degree. C. until analyzed. To analyze cytokine secretion upon restimulation cells were collected from day 12 to 14 of culture in complete X-Vivo 15 media, washed and resuspended in basal media at 37.degree. C. for 3 hours to rest. Cells were then collected and resuspended in complete X-Vivo 15 media and stimulated for 48 hours at 37.degree. C. with 1 .mu.g/mL plate-bound anti-CD3. Cell supernatants were then collected and stored at .sup.-80.degree. C. until analyzed.

[0244] Lentiviral Construction and Transfection Protocol.

[0245] Lentiviral packaging constructs psPAX2 and PDM2.G were kind gifts of Dr. Nir Hacohen, Broad Institute. shRNA constructs against CD55 or empty vector were purchased from Sigma-Aldrich.RTM. (St. Louis, Mo., USA). To generate lentiviral particles, 1.2.times.10.sup.6 HEK293T cells were seeded in each well of a six well plate the day prior to transfection. Cells were then cotransfected using lipofectamine 2000 (Invitrogen.TM., Carlsbad, Calif., USA) with 900 ng of psPAX2 and 100 ng of pDM2.G, together with 1 .mu.g of the vector of interest (shRNA or lentiCRISPRv2). Alternatively, lentivirus was produced by the conventional calcium chloride transfection method. Supernatants were harvested 24 and 48 hours after transfection and frozen at .sup.-80.degree. C. HT29 cells were transduced by spin infection with lentivirus. Lentivirus and 8 .mu.g/ml Polybrene (Sigma-Aldrich.RTM., St. Louis, Mo., USA) were added to the wells of a 24-well culture plate and centrifuged at 2000 rpm and 37.degree. C. for 2 hours. Lentivirus-containing media was then replaced with 293T media, and the cultures were maintained as described above. On day 5 of culture, puromycin (Sigma-Aldrich.RTM., St. Louis, Mo., USA) was added to a final concentration of 2 .mu.g/ml to select for virally transduced cells. Selected cells were maintained in 2 .mu.g/mL puromycin following initial selection.

[0246] CRISPR Materials/Methods.

[0247] CRISPRs targeting CD55 were designed using an online tool (crispr.mit.edu) as previously described and cloned into a lentiCRISPRv2 vector (Ran F A et al. Genome Engineering using the CRISPR-Cas9 system. Nature Protocols 2013; 8: 2281-308; and Sanjana N E, et al. Improved vectors and genome-wide libraries for CRISPR screening. Nat Methods 2014; 11: 783-4). CRISPR lentivirus was produced according to the above protocol. Transductions were performed as above, with minor changes. For Jurkats, selection with 1 .mu.g/mL puromycin was performed for 3 days. For Caco-2, selection with 5 .mu.g/mL puromycin was performed for 6 days, changing the media every 2 days.

[0248] HUVEC Experiments.

[0249] Huvecs grown to 80% confluency, and before passage 8, were trypsonized and replated in 24 well tissue culture plates at 200,000 cells/well in Huvec media. Twenty-four hours later the indicated concentrations of TNF.alpha., IL10, or all trans retinoic acid (ATRA) were added. Twenty-four hours later in the cast of TNF.alpha. or IL10 treatment or 48 hours later in the case of ATRA, cells were trypsonized and stained for the indicated surface markers following the described flow cytometry staining protocol. Cells were then immediately analyzed.

[0250] Western Blotting.

[0251] CD4.sup.+ T cells were washed in PBS and lysed in 1% Triton X-100, 50 mM Tris-C1, pH 8, 150 mM NaCl, 2 mM EDTA, 10% glycerol, complete protease inhibitor cocktail (Roche Diagnostics, Indianapolis, Ind., USA), and phosphatase inhibitor cocktails (Sigma-Aldrich.RTM., St. Louis, Mo., USA) on ice for 20 minutes. The lysates were then clarified by centrifugation at 15,000.times.g at 4.degree. C. for 10 minutes. Protein concentration was determined by BCA assay (Thermo Fisher Scientific.RTM., Waltham, Mass., USA). Lysates were then diluted with 2.times. SDS sample buffer (quality biologicals) supplemented with 5% BME to make reducing sample buffer. Approximately 5 .mu.g of total protein was separated by SDS-PAGE on 4-20% precast gels (Invitrogen.TM., Carlsbad, Calif., USA) and transferred to a nitrocellulose membrane (Bio-Rad Laboratories, Philadelphia, Pa., USA). Membranes were blocked with 5% nonfat dry milk in Tris-buffered saline (TBS) with 0.01% Tween-20 (TBST) for 30 minutes at room temperature before incubating with primary antibody overnight at 4.degree. C. After three 5 minute washes with TBST at room temperature with rocking, HRP-conjugated secondary antibody was added for an additional hour at room temperature. After five 5 minute washes, HRP substrate (Luminata Forte; EMD Millipore, Billerica, Mass., USA) was added to the membranes, which were then exposed to autoradiography film and developed.

[0252] Statistical Analysis.

[0253] Statistics were computed using the analysis options in Prism (Graphpad Software, Inc., La Jolla, Calif., USA). Either the Mann-Whitney U test or a two-tailed unpaired T test with Welch's correction was used to compare sample means. *=p<0.05, **=p<0.01, ***=p<0.001.

[0254] Patient Clinical Histories.

[0255] Patient 1.1, a 7 year-old girl born to consanguineous Turkish parents, presented with bloody diarrhea and vomiting at 4 weeks of age, and continued with episodes throughout childhood. At 6 months of age, she was admitted to hospital with persistent diarrhea, pneumonia, and facial/extremity edema, for which she received antibiotics and albumin replacement therapy. Endoscopic examination revealed ulcers, exudate formation and nodularity in the colon. Although the patient's gastrointestinal (GI) symptoms improved with treatment and she subsequently gained weight, long-term remission could not be achieved. The patient was placed on infliximab therapy at 6 years of age to deal with ongoing GI symptoms. Apart from GI symptoms she experienced recurrent respiratory infections at an unusually high frequency from 6 months of age. Immunologic evaluation revealed pan-hypogammaglobulinemia and she was treated with intravenous immunoglobulin (IVIG), leading to a decrease in the frequency of infections. To determine the specific antibody production we tested isohemagglutin levels, with normal Anti-A and Anti-B titers. Despite WIG, trough levels of IgG remained below the desired range, and tracked well with levels of serum albumin (FIG. 1B). Fecal excretion of alpha-1 antitrypsin was found to be elevated, implying the role of protein losing enteropathy in refractory hypogammaglobulinemia. In addition to the biallelic loss of function in CD55, this patient was additionally positive for a homozygous LOF mutation in CD21 that resulted in loss of protein expression (data not shown).

[0256] Patient 2.1, a 22-year-old female born to consanguineous Turkish parents, presented with fever, productive coughing and hemoptysis at the age of 6 years when she was diagnosed with pneumonia. She continued to have recurring respiratory symptoms with breathing difficulty, wheezing, chronic coughing, and multiple attacks of pneumonia leading to the development of bronchiectasis and finger clubbing. Following the onset of respiratory illness, she developed GI complaints, with abdominal pain and distention, diarrhea, and, eventually, cessation of growth. Clinical presentation included vomiting, diarrhea, periorbital and pretibial edema and she was found to have hypoalbuminemia and decreased serum levels of Vitamin B12, folate, iron, and hypothyroxinemia. When she was 11 years old her serum immunoglobulins levels were determined due to suspected immunodeficiency. These tests revealed hypogammaglobulinemia and she was started on IVIG replacement therapy. While on IVIG the frequency of infections decreased substantially, leading to the recovery of bronchiectasis. Despite IVIG, serum immunoglobulin G levels remained within the lower range and correlated with the serum albumin levels over time, suggesting the loss of immunoglobulins through the GI tract (FIG. 1B). In order to assess the patient's capacity to produce specific antibodies, we evaluated isohemaglutinin titers and antibody response to pneumococcal vaccine, with normal results. After several years of loss to follow up, she presented to the gastroenterology clinic with persisting symptoms and received treatment for IBD. Despite treatment, she experienced symptoms of intestinal obstruction at the age of 22 years and underwent surgery for the resection of the narrowed intestinal segment (FIG. 1H). The resection material showed fissuring ulcers, cryptitis and crypt abscesses, villous blunting, diffuse epithelial regeneration, and dramatic lymphangiectasis.

[0257] Patient 3.1, a 16-year-old boy born to consanguineous Turkish parents, presented with edema due to hypoalbuminemia at 27 months of age. Serial colonoscopies revealed progressive macroscopic hyperemic lesions with ulcers, cryptitis, crypt abcess, and lymphoid cell infiltration that did not respond to steroids and azathioprine treatment alone. Over time, addition of mesalazine to treat IBD and supplementation therapy with calcium, vitamin B12 and folic acid led to clinical improvement. Of note, the patient did not present with classical VEO-IBD symptoms such as bloody stools at the beginning of the disease. The patient presented with protein losing enteropathy with hypoalbuminemia and serial serum immunoglobulin investigation revealed reduced levels of IgG. Lymphocyte counts were also reported as normal. This patient has not, as of yet, presented with recurrent/severe lower respiratory tract infections despite hypogammaglobulinemia. In addition, no infectious trigger was found throughout GI episodes indicated by normal C-reactive protein (C-RP) levels, as well as a normal erythrocyte sedimentation rate (ESR).

[0258] Patient 4.1, a 3-year-old girl born to consanguineous parents, presented with puffy eyes, diarrhea and vomiting at 1 year of age. She continued to have recurrent episodes of periorbital and pretibial edema, mostly triggered by the bouts of bloody and mucous diarrhea. She was found to have persistent hypoalbuminemia, for which she received intermittent albumin infusions. Evaluation for other serum proteins revealed hypogammaglobulinemia, with low IgG, IgA and IgM levels. At presentation, anthropometric indices revealed wasting with weight within the 3.sup.rd to 10.sup.th percentile and height within the 50.sup.th percentile for her age. The patient currently receives supplementation therapy for the deficiency of vitamin B12. Despite low immunoglobulin levels she has not experienced any significant or recurrent infections as of yet. Evaluation for infectious etiology during attacks of diarrhea and vomiting proved negative, along with normal levels of inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Evaluation for the differential diagnoses including food allergy and cystic fibrosis or celiac disease was also negative.

[0259] Patient 4.2, a 17 year-old boy and brother of Patient 4.1 and 4.3, has a history of occasional and self-limiting presentations with facial and extremity edema, for which no medical intervention was required. Despite testing positive for hypogammaglobulinemia, he denied any history of infections of unusual severity or frequency. The patient has not experienced any significant GI symptoms thus far.

[0260] Patient 4.3, an 18-year-old boy and brother of patient 4.1 and 4.2, has been mostly asymptomatic. Laboratory evaluation revealed low-normal levels of serum proteins and vitamin B12. The patient has not experienced any significant GI symptoms thus far, and has not reported any history of edema.

[0261] Patient 4.4 was an affected female cousin of patients 4.1-4.3 with an unknown genotype. Clinically, this patient presented with recurrent facial and extremity edema, chronic bloody diarrhea, chronic malnutrition, low serum protein levels, with hypoalbuminemia (albumin: 1.9 g/dl) and hypogammaglobulinemia. Histopathology revealed the presence of dramatic lymphangiectasis in the small intestine. The patient was treated with immunosuppressive treatment including steroids and azathioprine due to suspected IBD. Interestingly, she had a history of thrombosis and cerebral vascular disease with hypodense brain lesion in the lateral ventricule and received anticoagulation therapy with low molecular weight heparin. Angiographic studies demonstrated various vascular pathologies at the intra-abdominal and cerebral vessels including: (1) narrowed superior mesenteric vein with multiple collateral veins, suggestive of chronic thrombosis, and (2) decreased blood flow in internal carotid arteries, particularly in cavernous and intracranial segments and undetectable middle cerebral artery. She eventually developed an intestinal obstruction and underwent intestinal resection surgery to remove the narrow segments. Histopathological evaluation of the resection material revealed lymphangiectasia, a focus of ulceration, and abundant ectatic vascular elements with vessel wall thickening. At 33 years of age, this patient died of thrombosis, cardiac arrhythmia, and respiratory distress syndrome developing after surgical resection to remove a severe intestinal obstruction. We were unable to successfully obtain a genetic analysis of this patient due to not having access to patient tissue.

[0262] Patient 5.1 is a 10-year-old boy and the sibling of Patient 5.2 born to consanguineous Turkish parents. The patient was first admitted to a hospital at the age of one year with diarrhea and vomiting. He was diagnosed with intestinal lymphangiectasia with severe hypoproteinemia, with low albumin and immunoglobulin levels. The patient required frequent albumin infusions and was put on a protein rich diet with medium-chain triglyceride (MCT) supplements. At the age of 7 years old, Patient 5.1 underwent abdominal surgery for the resection of lymphangiectatic segments, which led to a temporary recovery of his symptoms. He has had multiple recurrent thrombotic events in mesenteric and hepatic veins, as well as in the vena cava inferior, atrial and ventricular thrombosis. He received anticoagulation treatment with warfarin following cardiac surgery for atrial thrombosis. He also presented with intracranial bleeding and underwent neurosurgical operations. Currently, the patient is prescribed octreotide irregularly. The patient is not reported to have an increased rate of respiratory infection despite low immunoglobulin levels. There was no evidence of gastrointestinal infection, and sweat chloride test, celiac markers, and lipid profiling were normal. Colonic biopsy revealed edema and eosinophilic infiltrates, from which a diagnosis of eosinophilic colitis was made. The patient is in poor condition and requires frequent hospital admissions.

[0263] Patient 5.2, is the 12-year-old affected sister of Patient 5.1. The patient presented with frequent abdominal pain, and a similar manifestation of hypogammaglobulinemia and hypoalbuminemia as Patient 5.1, which required frequent albumin transfusions. Due to episodes of intestinal obstruction, she underwent resection of edematous small bowel segments to remove lymphangiectatic segments, upon which she experienced some clinical remission. Of note, this patient did not present with any thrombotic events, infectious history, or bloody diarrhea.

[0264] Patient 5.3, an affected sister of patients 5.1 and 5.2 of unknown genotype, was admitted at 15 months old with complains of eyelid and extremity edema and diarrhea. The patient presented with hypoalbuminemia, hypogammaglobulinemia, thrombocytosis and anemia. Endoscopy and histopathological examination of the duodenum revealed intestinal lymphangiectasis. The patient had severe malnutrition, with reduced levels of calcium, magnesium, and phosphorus and various vitamins. The patient was treated with intravenous calcium, albumin, vitamin, and mineral supplements on top of medium chain triglyceride supplements and octreotide. These treatments led to temporary clinical improvement. Small bowel resection was performed three times over a period of 2 years with only transient clinical improvement. Parenteral nutrition efforts were interrupted by Candida and S. Aureus infections along with sepsis. She developed a thrombus in the vena cava superior leading to vena cava superior syndrome and anti-thrombotic treatment with low molecular weight heparin and tissue plasminogen activator was initiated. The patient developed ascites, pleural effusion, and pulmonary infection and died when she was 4.5 years old.

[0265] Patient 6.1, a 15-year-old boy born to consanguineous Turkish parents, presented with facial and extremity edema at 1.5 years of age and was found to have hypoalbuminemia. He had frequent hospital admissions due to vomiting, diarrhea and abdominal pain. Endoscopic examination revealed intestinal lymphangiectasia and he was put on steroid treatment. Evaluation for common causes of secondary lymphangiectasia including heart diseases and abdominal mass lesions was negative. Upon persistence of his symptoms he was started on octreotide treatment and prescribed a diet low in fat and high in high quality protein along with MCT supplements. Along with chronic gastrointestinal symptoms he developed deficiencies in the major micronutrients and vitamins such as iron, calcium, magnesium and vitamin D leading to growth retardation. Frequent exacerbations of facial and extremity edema and abdominal symptoms in relation to severe intestinal wall edema (FIG. 1C) required repeated albumin transfusions. In line with the low albumin levels, serum immunoglobulins were also decreased (Table 2, shown as FIG. 4). Apart from chronic gastrointestinal symptoms he experienced frequent respiratory symptoms with chronic cough and finger clubbing. Computed tomography of the chest revealed fibrotic changes in the posterobasal lung segments. When he was 14 years of age, he suffered severe thrombotic events, with a thrombus originating from a stalk 2 cm distal to the inferior vena cava (IVC) extending into the right atrium, which was impairing the venous blood flow. He also had thrombi in the pulmonary arteries. He underwent thoracic surgery for thrombectomy and was commenced on anticoagulation treatment with low molecular weight heparin and low dose aspirin. Despite prophylactic anticoagulation treatment, during the follow up he experienced recurrence of thrombosis with reformation of the clot in the right atrium. Screening for common congenital hypercoagulable states such as Factor V Leiden or prothrombin G20210A mutations that lead to over activity of coagulation factors, or arising from a deficiency of the natural anticoagulants Protein C, S and anti-thrombin III was negative. The patient was found heterozygous for the thermolabile variant of the methylenetetrahydrofolate reductase (MTHFR) gene, C677T and no A1298C mutation was observed in this gene along with normal plasma homocystein level, suggesting no increased risk of thrombosis attributable to hyperhomocysteinemia. The patient was also tested for anticardiolipin and anti-phospholipid antibodies and for paroxysmal nocturnal hemoglobinuria through Fluorescein-labeled proaerolysin (FLAER) flow cytometry assay, with negative results. The patient currently suffers a debilitating disease with frequent hospital admissions.

[0266] Patient 7.1, a 4-year-old girl born to consanguineous Syrian parents, presented with facial and extremity edema at 1 year of age, with continued relapses thereafter. She has experienced recurrent gastrointestinal symptoms, with chronic diarrhea and was found to have hypoalbuminemia. She was diagnosed with suspected intestinal lymphangiectasia and commenced on octreotide treatment. She has growth retardation, with height for age below the 3.sup.rd percentile. Due to micronutrient deficiencies she received supplementation therapy with vitamin D, vitamin B 12, multivitamins, and was transfused with erythrocyte suspension due to anemia. She was prescribed a diet low in fat and high in high quality proteins, MCT supplements, and further supplementation by enteral feeding and albumin transfusion as required. Measurement of serum immunoglobulins revealed low IgG, IgA and IgM (Table 2). Immunologic evaluation revealed normal isohemaglutinin titers and the proportion of the lymphocyte subsets was within normal limits. She has experienced recurrent lower respiratory infections and received parenteral antibiotics and was put on prophylactic antibiotic treatment with co-trimoxazole.

[0267] Clinical Phenotype.

[0268] Demographic data and the clinical presentations of the 10 patients in the study are shown in Table 2 (FIG. 4), and patient descriptions were described above. Patients 1.1-3.1 were born to unaffected consanguineous parents with a distinct PLE syndrome comprising severe hypoalbuminemia, hypogammaglobulinemia and chronic diarrhea. After gene discovery in these initial cases, additional patients were found by evaluating early-onset PLE patients.

[0269] Overall, patients presented with facial and extremity edema accompanied by chronic persistent bloody diarrhea with remissions and exacerbations in disease severity (Table 3). Individual patients had additional disease manifestations, some with multiple thrombotic events and vascular alterations and others having a history of recurrent respiratory infections.

[0270] All patients exhibited persistent hypoproteinemia, with reductions both in albumin and gammaglobulins (FIG. 1B and FIG. 5A). The degree of hypoproteinemia and the severity of symptoms varied among individual cases. Patients 4.2 and 4.3 had mild disease with occasional facial and extremity edema whereas others had profound hypoalbuminemia and a severe progressive disease course (Table 2). Radiological exams, taken from patients in the presence of acute GI symptoms, showed that the patients had bowel wall edema/thickening (FIG. 1C, arrows) sometimes together with partial intestinal obstruction, which responded favorably to albumin replacement therapy. The hypoproteinemia was attributed to GI protein loss because the nadir of albumin levels correlated with the flares of bloody and mucous diarrhea and increased excretion of .alpha.-1 antitrypsin was detected in feces in Patient 1.1. Other causes of hypoproteinemia, including hepatic disease, decreased nutritional intake, or heavy proteinuria, were excluded in all cases. Endoscopic evaluation revealed relatively mild alterations in the mucosa given the severity of protein loss, whereas histopathology of small intestinal biopsies demonstrated dilatation of the lacteals and distension of the lymphatic vessels in Patients 2.1, 5.1, 5.2, 6.1 and 7.1 (Table 2, FIG. 1D). Evaluation for common systemic conditions that could lead to secondary lymphangiectasia, such as cancer, heart disease or obstructive lesions involving the lymphatic system, was negative, indicating a diagnosis of primary intestinal lymphangiectasia as the cause of PLE. Surgical removal of the localized lymphangiectatic segments in Patients 5.1 and 5.2 resulted in substantial, but temporary, reversal of PLE in the case of Patient 5.1, and symptom alleviation in the case of Patient 5.2.

[0271] The patients eventually developed an intestinal malabsorption syndrome, with anemia and major micronutrients deficiencies including iron, calcium, magnesium, folate and vitamins D and B12, ultimately leading to retarded growth (Table 2 and FIGS. 5B and 5C). Supplementation therapy with vitamins and micronutrients along with dietary modification and albumin and blood transfusions as required led to improved growth in some of the patients, whereas others had a more refractory course with progressive malnutrition (FIG. 5).

[0272] Some of the patients had hypercoagulability with recurrent thrombosis and vascular alterations. Patient 6.1, who initially had relatively stable GI disease, developed severe thrombotic disease during follow up. Large occlusive thrombi occurred in the inferior vena cava (IVC) and right atrium together with thrombi in the pulmonary arteries (FIG. 1E, left panel), which was accompanied by arteriovenous malformations in the lung (FIG. 1E, center and right panels). Despite surgical removal of blood clots and anticoagulation therapy, continuing thrombosis caused an overall worsening of symptoms. Similarly, Patient 5.1 had multiple thrombotic events in the mesenteric and hepatic veins as well as the right atrium and ventricle, which was treated with low molecular weight heparin anticoagulation. He also had a history of intracranial hemorrhage, which required cranial surgery. Of note, a cousin of Patients 4.1-4.3 and a sibling of Patients 5.1 and 5.2 (FIG. 3), with undetermined genotypes, had a similar course of disease leading to death at 33 and 4.5 years of age respectively. These patients presented with PLE with lymphangiectasia leading to malnutrition, and a history of thrombotic events, which in Patient 4.4 led to cerebral ischemia, mesenteric vein narrowing with development of multiple collateral vessels and histopathologic evidence of ectasia of the vascular elements in the submucosa of the small intestine. Patient 4.4 died of cardiac, thrombotic, and respiratory complications following surgery to remove an intestinal obstruction, while Patient 5.3 died following development of ascites, pleural effusion, and pulmonary infection.

[0273] Some of the patients had endoscopic and histopathology features resembling Crohn's disease although without granulomas. Patients 1.1-3.1 showed mucosal ulcers and inflammatory exudate in the terminal ileum and colonic sites (FIG. 1F). In the endoscopic biopsy materials from Patients 1.1, 2.1, and 3.1, there were mixed infiltrates of T and B cells, sometimes with eosinophils (FIG. 1G). Although these three patients received recommended therapy for IBD that reduced their bowel symptoms, a sustained remission was not achieved and GI protein loss continued (Table 2, FIG. 1B, and Figure. 5). Patient 2.1, who recently developed symptoms of intestinal obstruction, underwent surgical resection of a narrowed ileal segment (FIG. 1H) which included dilated lymphatic vessels, leading to resolution of GI symptoms, weight gain and recovery of serum albumin levels during the short term follow up (not shown). None of the patients exhibited extraintestinal manifestations commonly associated with IBD, such as skin eruptions, perianal lesions, fistulas or uveitis.

[0274] Patients 1.1, 2.1, 6.1, and 7.1 experienced recurrent respiratory infections in association with hypogammaglobulinemia (Table 2, FIG. 1B (arrows)), while other patients did not report any significant or recurrent infections. As major immunological subsets and specific antibody production were largely normal in the patients (Table 3), it is believe these infections were largely due to loss of serum immunoglobulins. Clinical evaluation of patient peripheral blood immunological subsets of Table 3, provided as either (cells/mm.sup.3) or % of total cells. Notably, use of intravenous immunoglobulin (IVIG) replacement therapy decreased the frequency of infections in Patients 1.1 and 2.1 and led to resolution of bronchiectasis in Patient 2.1.

[0275] Identification of CD55 Mutations.

[0276] Given the consanguinity in all families under study, an autosomal recessive (AR) mode of inheritance was assumed. WES in Patients 1.1 and 2.1, and combined with homozygosity mapping in Patient 3.1 and 5.1 as described previously (Dobbs K, et al., Inherited DOCK2 Deficiency in Patients with Early-Onset Invasive Infections. The New England Journal of Medicine 2015; 372: 2409-22), revealed potentially deleterious homozygous loss-of-function (LOF) mutations in CD55/Decay Accelerating Factor (DAF), showing perfect segregation under assumption of AR inheritance. CD55 is a negative regulator of the complement cascade ubiquitously expressed on the surface of eukaryotic cells (FIG. 6A). The CD55 nucleotide variants were confirmed by Sanger DNA sequencing (FIG. 3). Additional patients were then screened with a diagnosis of PLE and identified 5 additional patients from Families 4, 6, and 7 with rare biallelic CD55 LOF nucleotide variants. Patient 1.1 and 7.1 were homozygous for dinucleotide deletion and 4 nucleotide insertions at position c.149-150 and patients 2.1, 3.1, 5.1 and 5.2 were homozygous for a single base pair deletion at position c.109, each resulting in frameshift and premature termination codons in CD55. In Family 4, a novel homozygous missense mutation was identified (c.800G>C) in CD55 resulting in a single amino acid substitution (p.Cys267Ser) in the 4.sup.th short consensus repeat (SCR) domain, predicted by computational analyses to be deleterious. In Family 6, a mutation was found in the splice acceptor site of exon 3. The locations of the identified mutations within the CD55 protein/gene are depicted in FIG. 6B, and deleterious predictions are shown in Table 4. Mutation and impact score of Table 4 were calculated from indicated predictive algorithm (either the SIFT, Polyphen2 and CADD algorithms). This scoring system was not applicable (N/A) to frameshift or splice site mutations present in majority of our patients. Predictions were based on a reference sequence from ENST00000367064, GRCh37. Altogether, we identified 4 distinct homozygous, novel rare mutations in CD55 in a total of 11 patients of Turkish (2 with unknown genotype), and 1 of Syrian origin (FIG. 6B).

[0277] Effects of CD55 Mutations on Messenger RNA and Protein Expression.

[0278] Patients 1.1, 2.1, 3.1, 5.1, and 5.2 harbored frameshift mutations that led to nonsense-mediated loss of mRNA in 1.1 and 2.1 (FIG. 6C). The mutation present in Patients 4.1, 4.2, and 4.3 is a missense mutation (p.Cys267Ser) that does not alter mRNA expression level (FIG. 6C). Cys267 participates in an intrachain disulfide bond with Cys225 and loss of this bond could lead to CD55 protein misfolding and degradation (FIGS. 7A and 7B) (Nakano Y, et al. Complete Determination of disulfide bonds localized within the short consensus repeat units of decay accelerating factor (CD55 antigen). Biochim Biophys Acta 1992; 1116: 235-40). Absent, or severely reduced, CD55 surface expression was observed by flow cytometry or western blot in all patients (FIGS. 6D and 6E). Patient 6.1, harboring a splice acceptor site mutation, is the only patient with residual protein expression by flow, possibly suggesting exon skipping.

[0279] Increased Complement Deposition on CD55-Deficient Cells.

[0280] As CD55 is a negative regulator of the complement pathway, it was hypothesized that CD55 deficiency would lead to increased C3 cleavage and deposition on host cells. Activation of the alternative pathway, marked by C3 cleavage, can be enhanced by serum acidification, used previously for the diagnosis of paroxysmal nocturnal hemoglobinuria (PNH) (Ham T H, et al., Studies on Destruction of Red blood Cells. Li. Chronic Hemolytic Anemia with Paroxysmal Nocturnal Hemoglobinuria: Certain Immunological Aspects of the Hemolytic Mechanism with Special Reference to Serum Complement. J. Clin Invest 1939: 18: 657-72). Hence, control CD4.sup.+ T-cell blasts, which highly express CD55 on their cell surface (FIG. 6D), were compared with those from patients after incubation with normal or acidified pooled normal human serum (nHS), both of which caused surface deposition of the complement split product C3d. We observed that C3d was deposited to a greater degree on T cells from multiple patients compared to controls (FIG. 8A). Increased complement activation was due to loss of CD55 as lentiviral transduction of patient T-cell blasts with CD55 protected them from complement deposition (FIG. 8B). The finding was verified on Jurkat T cells, which also constitutively express cell surface CD55, after CRISPR-mediated deletion of the CD55 gene. Increased C3d deposition was observed in the genetically deficient (CD55-) compared to CD55-expressing (CD55+) Jurkat cells (FIG. 8C). C3b (not shown) was unable to detect, suggesting that deposited C3b is rapidly degraded, possibly by serum factor I and the cofactor CD46 or factor H (FIG. 6A). It is known that human intestinal epithelial cells (IECs) express CD55, and that it is upregulated upon TNF.alpha. treatment. Thus, it was hypothesized that it may protect IECs from complement activation and damage by anaphylatoxin signaling or direct attack of the terminal complement cascade. We therefore knocked down CD55 in the human IEC line HT29 using lentiviral shRNA transduction and found that this permitted increased C3d deposition. Using various conditions, it was found that the CD55 mean fluorescent intensity (MFI) was inversely correlated with C3d staining indicating that as the level of surface CD55 decreases, the activation of complement increases (FIG. 8D). In all cell types tested, lack of CD55 in patient cells led to increased complement deposition, however, serum/complement-mediated cell death was not observed (FIG. 8E), suggesting that CD55-deficient cells allow early steps in complement activation to occur, but this does not progress to terminal formation of the "membrane attack complex" (MAC).

[0281] CD55-Deficient T Cells have an Increased Inflammatory Cytokine Profile.

[0282] Complement proteins are mainly produced in the liver, but also locally by cells of the immune system (dendritic cells and T cells). Immune cell complement can provide costimulatory and Thl differentiation signals to T cells through either CD46-mediated sensing of deposited C3b or through the C3a/C5a anaphylatoxins signaling through the anaphylatoxin receptors (AnR) C3aR and C5aR. CD55 governs complement activation and consequent immune stimulation. Cytokine secretion by patient CD4.sup.+ T cells was measured during primary and secondary stimulation with TCR agonistic antibodies and found increased TNF.alpha. and less IL-10 production compared to controls (FIGS. 9A, 9B, 10A, and 10B). No consistent differences were detected for IFN.gamma. secretion (FIGS. 9C and 10C). To determine if the altered cytokine secretion was dependent on increased AnR signaling, small molecule inhibitors of C3aR and C5aR1 were used to block anaphylatoxin signaling. AnR inhibition decreased overall TNF.alpha. production and abrogated the difference between patient cells and controls (FIG. 9A). However, AnR inhibition did not rescue IL-10 production in patient T cells suggesting that the IL-10 secretion defect did not require AnR stimulation. Activated human CD4.sup.+ T cells expressed C3aR, but not C5aR1 or C5aR2, suggesting that C3a may play a larger role than C5a in T-cell activation (FIG. 9D). Interestingly, surface expression of C3aR on T cells depended on the presence of all trans retinoic acid (ATRA) and there was comparable expression between patient and control cells (FIG. 9E). As previously demonstrated, T cells grown in the presence of ATRA expressed the chemokine receptor CCR9 and the integrin .alpha.4.beta.7 that promote gut homing (FIGS. 10D and 10E). This suggests that gut homing T cells are also best suited to respond to anaphylatoxin products of complement activation.

[0283] In addition to complement regulation, CD55 mediates a co-stimulatory signal through interactions with CD97 that enhances T-cell activation and the production of the anti-inflammatory cytokine IL-10. Patient cells failed to respond to anti-CD55 or CD97, the natural ligand for CD55, mediated costimulation as reflected by CD69 and CD25 upregulation and proliferation (FIG. 10F-10H). Additionally, patient T cells lacked CD55-dependent IL-10 production (FIGS. 9F and 101). Taken together, these data demonstrate a critical role for CD55 in controlling complement and non-complement mediated production of proinflammatory and anti-inflammatory cytokines, respectively.

[0284] TNF.alpha. and ATRA Regulate Complement and Coagulation Regulatory Proteins on Endothelial Cells.

[0285] CD55-deficient patients are susceptible to thrombotic events, suggesting an abnormality in the regulation of the coagulation cascade Inflammatory cytokines, such as TNF.alpha., can modulate the coagulant and thrombotic properties of endothelial cells by down regulating thrombomodulin TM and up regulating tissue factor (TF) expression. As T cells from the patients make more TNF.alpha. compared to controls, next it was determined how TNF.alpha. modulates complement and coagulation. As previously demonstrated, TNF.alpha. treatment induces procoagulatory TM and TF expression on the surface of treated endothelial cells (FIGS. 9G and 9H). Interestingly, inventors also found that TNF.alpha. treatment decreased CD46 and CD59 expression, while modestly increasing CD55 expression on endothelial cells (FIG. 9I-9L). It was previously determined that ATRA increased surface expression of C3aR on human CD4.sup.+ T cells and next sought to determine if ATRA similarly affected endothelial cells. While no expression of C3aR, C5aR, or C5aR2 was found on HUVEC cells either with or without ATRA addition (data not shown), ATRA treatment did result in a dose-dependent decrease in thrombomodulin expression with a concomitant increase in CD55 expression and no change in either CD46 or CD59 (FIGS. 9M-9P). Combined, these data suggest that the proinflammatory cytokines preferentially secreted by patient immune cells predispose endothelial cells to the activation of both the complement and coagulation cascades. This may be further exacerbated by high local concentrations of ATRA, which are often found in intestinal tissues due to dietary intake and absorption of retinols.

[0286] Compstatin Inhibits C3d Deposition on Human Cells.

[0287] FIG. 11A illustrates that Compstatin inhibits C3d deposition on human T cells. C3d deposition was substantially increased in patient T cells treated with 5% nHS, as compared to control treatments and T cells. The increase was substantially inhibited by the addition of 100 .mu.M Compstatin. Similarly, as shown in FIG. 11B, the ratio of C3a to C4a in culture supernatants from patient T cells after 24 hours of incubation with 5% nHS 100 .mu.M Compstatin was considerably decreased relative to patient samples not treated with Compstatin. In FIG. 11C, the ratio of C5a to C4a in culture supernatants of patient T cells after 24 hours of incubation with 5% nHS and 100 .mu.M Compstatin is decreased, as compared to patient T cells not treated with Compstatin. ***=p<0.001.

[0288] Discussion

[0289] A severe chronic syndrome of inherited PLE is described with lymphangiectasia, thrombotic angiopathy, and atypical IBD caused by loss-of-function (LOF) mutations in the CD55 gene. Our results show that loss of CD55 causes dysregulated complement activation, anaphylatoxin signaling, inflammatory cytokine production, and thrombophilia via induction of the coagulation cascade. CD55 deficiency, Hyperactivation of complement, Angiopathic thrombosis and Protein Losing Enteropathy (CHAPLE) syndrome is defined herein as a heritable cause of complement-mediated lymphangiectasia. The cohort described herein shows that CHAPLE syndrome presents with variable expressivity, from subclinical to life threatening presentations, potentially explaining the variation in intestinal disease previously associated with the Inab phenotype.

[0290] Complement is a tightly regulated system of plasma and cell surface proteins that promotes the phagocytosis and destruction of microbes and modulates the local immune response through soluble anaphylatoxins. Inherited or acquired defects in complement inhibitory proteins lead to distinct syndromes in different organ systems which include paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), dense deposit disease, and age-related macular degeneration (FIG. 6A). PNH results from somatic mutations of the PIGA gene in hematopoietic precursors. This leads to the loss of GPI-anchored complement inhibitory proteins, including CD55 and CD59, causing terminal-complement mediated hemolysis with secondary thrombotic risk due to platelet activation. Germline LOF mutations affecting the complement regulatory proteins Factor H, Factor I, and CD46 or the anti-coagulatory protein thrombomodulin, result in the development of aHUS which is characterized by activation and damage of glomerular microvascular endothelial cells by complement intermediates and the membrane-attack complex, hemolysis due to mechanical injury, and kidney failure due to microthrombotic angiopathy. Defects in these same genes can cause age-related macular degeneration due to complement deposition in the retina. Unlike PNH and aHUS, hemolysis or kidney failure was not observed in CHAPLE patients. By contrast, CHAPLE patients, like PNH and aHUS patients, have an increased risk of thrombosis, highlighting that excessive complement activation can lead to induction of the coagulation cascade. The differences in clinical phenotype between PNH, aHUS, and CHAPLE syndrome may be due to varying cellular tropisms of the affected complement regulatory proteins or due to differences in the extent of complement activation. For instance, hemolysis or complement-dependent cell death was not detected in CHAPLE patients, suggesting little, if any, membrane-attack complex forms, differentiating this disease from PNH and aHUS.

[0291] Interestingly, it was observed that CD55 deficiency primarily manifests as an intestinal disease, occasionally complicated by life-threatening thromboembolism. The locations affected by thrombotic disease in CHAPLE patients (abdomen and brain) was similar to PNH and dissimilar to aHUS, which primarily affects the kidneys. This may reflect expression patterns of CD55 and other complement regulatory proteins. Supporting this idea, CD55 protein expression was found to be increased on endothelial cells in response to both TNF.alpha. and ATRA. During normal immune responses TNF.alpha. induction of CD55 may limit complement activation and prevent host damage. ATRA is a biologically active metabolite of Vitamin A/retinol, which is strictly acquired through diet. As such, intestinal tissues are exposed to a high amount of retinol and its metabolites and these metabolites play key roles in controlling the intestinal innate and adaptive immune response. Another possibility is that the constant microbial challenge in the intestinal tract predisposes this area to complement activation and activation of innate and adaptive immune responses, which may be hyperactivated by the absence of CD55. Additionally, TNF.alpha. and IL-10, whose production is altered in patient T cells, are critical for the regulation of universal inflammatory responses and deficiency of these cytokines preferentially causes intestinal disease, suggesting that intestinal tissues are sensitive to changes in the inflammatory cytokine milieu. Given the observation that ATRA drives both C3aR expression and a gut homing phenotype on human CD4.sup.+ T cells, it is likely that T cells in the intestinal tissues are sensitized to the detection and activation by complement components. Collectively, these factors likely drive the intestinal disease associated with CD55 deficiency.

[0292] The hallmarks of CHAPLE syndrome or disease are early-onset PLE with lymphangiectasia and IBD. This is attributable to 3 relevant pathogenic mechanisms: i) impaired endothelial or epithelial barrier function due to signaling by anaphylatoxins or sub-lytic MAC deposition, ii) increased pressure due to thrombotic events, and iii) changes to the inflammatory cytokine environment. CD55-deficient mice show increased complement-dependent susceptibility to dextran sodium sulfate (DSS)-induced colitis, with complement deposition on IECs. The thrombotic events in CHAPLE patients, when localized to mesenteric tissue, may drive increased lymphatic pressure and exacerbate intestinal lymphangiectasia and chronic PLE. CD55-deficient patient T cells produce more TNF.alpha. and less IL-10, thereby creating a pro-inflammatory milieu. TNF.alpha. production was found to be dependent on anaphylatoxin signaling, while decreased IL-10 production was likely due to loss of CD55-mediated T-cell costimulation. CD55-deficient mice show similar alterations in cytokines. Taken together, these data show that complement activation is critical to disease pathogenesis (FIGS. 12A and 12B).

[0293] The patients with CHAPLE disease described herein have a chronic and severely debilitating, sometimes fatal, clinical course. As such patients with early-onset PLE should be screened for CD55 expression. CHAPLE patients have responded well to protein infusion and resection of localized lymphangiectatic intestinal segments; though albumin infusion provides only a transient palliation of symptoms and patients require ongoing treatment. Attempts to treat this disorder with conventional immunosuppressants, somatostatin analogues, or anticoagulants have been met with only a moderate degree of success in individual patients. Given the complement-mediated pathogenesis of this disorder, it is believed that agents that inhibit the complement-pathway (e.g., the complement-inhibitory monoclonal antibody Eculizumab, which has been used successfully in PNH and aHUS, or Compstatin), would be effective at treating CHAPLE patients. Eculizumab blocks C5 cleavage, thereby preventing the formation of the potent anaphylatoxin C5a and progression to the terminal complement cascade, two critical mediators of effector function in the complement cascade. While CD55 regulates the C5 convertase, making Eculizumab a good target therapy, it also regulates the C3 convertase. Furthermore, Compstatin is a peptide inhibitor (i.e., a cyclic tridecapeptide) of the complement system. In particular, Compstatin binds component C3, thereby inhibiting C3 activation/cleavage. As such, any complement-pathway inhibitors, including C3 convertase and C5 convertase inhibitors are possible therapeutic agents for treating patients with CHAPLE disease.
