Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 14/538,709, filed Nov. 11, 2014, which is a
continuation of U.S. patent application Ser. No. 14/495,732, filed
Sep. 24, 2014, now issued as U.S. Pat. No. 9,127,069, which claims
the benefit of U.S. Provisional Patent Application No. 62/012,112,
filed Jun. 13, 2014, all of which are herein incorporated by
reference in their entireties.
BACKGROUND
[0002] The receptor activator of nuclear factor .kappa.B (RANK),
receptor activator of nuclear factor .kappa.B ligand (RANKL), and
osteoprotegerin (OPG) triad (RANK/RANKL/OPG) play an important role
in immune response and bone metabolism. RANK/RANKL triggers a
network of TRAF-mediated kinase cascades that promote osteoclast
differentiation. RANKL is expressed on osteoblast cells and its
receptor, RANK, on pre-osteoclastic cells. The RANK/RANKL
interaction induces the differentiation and formation of
multinucleated mature osteoclasts, causing bone resorption. The
third protagonist, OPG, is also produced by osteoblasts and exerts
an inhibitory effect on the pre-osteoclastic differentiation
process. OPG, by binding to RANKL, inhibits the RANK/RANKL
interaction and subsequent osteoclastogenesis.
SUMMARY
[0003] Described herein are dosage forms comprising RANK/RANKL
antagonists for treatment of various diseases or medical
conditions.
[0004] Some embodiments include a method for treating pain

DETAILED DESCRIPTION
[0012] Provided herein are methods and compositions for treating
undesirable conditions or diseases, including pain. Generally, the
patient is a human, but the methods described herein may be applied
to any mammal, including domestic animals such as pets and farm
animals. Typically, a patient in need of treatment receives an
amount of a RANK/RANKL antagonist that is effective to treat pain
or another undesirable condition.
[0013] Some embodiments relate to the treatment of pain or other
undesirable conditions by blocking RANK/RANKL function. For
example, an effective amount of one or more RANK/RANKL antagonists
can be administered to a mammal, such as a human being, for the
treatment of pain or another undesirable condition.
[0014] A RANK/RANKL antagonist can be any chemical species having
the activity of RANK/RANKL antagonists as commonly understood in
the art, or can be an agent that partially or fully blocks,
inhibits, or neutralizes one or more biological activities of RANKL
or RANK, such as binding of RANKL to RANK, in vitro, in situ, or in
vivo. An antagonist may function in a direct or indirect manner.
For instance, the antagonist may directly bind to RANKL or RANK,
thus partially or fully blocking, inhibiting or neutralizing one or
more biological activities of RANKL or RANK, in vitro, in situ, or
in vivo. The antagonist may also function indirectly to partially
or fully block, inhibit or neutralize one or more biological
activities of RANKL or RANK, in vitro, in situ, or in vivo as a
result of interacting with, e.g., activating, inducing, blocking or
inhibiting, another compound that can bind to RANK or RANKL. The
antagonist may also function indirectly to partially or fully
block, inhibit or neutralize one or more biological activities of
RANKL or RANK, in vitro, in situ, or in vivo as a result of
modulating or affecting the production of RANKL or RANK.
[0015] "Treatment," "treating," or "therapy" includes its common
meaning in the field and includes diagnosis, cure, mitigation,
treatment, and prevention.
[0016] A RANK/RANKL antagonist can comprise a biomolecule, such as
a polypeptide or a protein, a nucleic acid, a polysaccharide, etc.,
or could be a small molecule, such as a compound having a molecular
weight that is less than about 2000, about 1000, about 500, etc.
"Polypeptide" as used herein includes its common meaning in the
field as well as molecules derived from two amino acids or
more.
[0017] A RANK/RANKL antagonist can be administered with one or more
additional therapeutically active agents. For example, a RANK/RANKL
antagonist can be administered simultaneously or administered
consecutively with a second therapeutically active agent.
[0018] There are a variety of polypeptides and proteins that can be
suitable RANK/RANKL antagonists. In some embodiments, the
RANK/RANKL antagonist can be a protein that can be derived from the
same species of animal as the patient or subject.
[0019] In some embodiments, patients in need thereof can treated by
administering a RANK/RANKL antagonist comprising a soluble RANK
protein that is capable of binding RANKL that can comprise all or a
fragment of the extracellular domain of a RANK protein. The patient
can be a human and the soluble RANK can be derived from a human
RANK polypeptide. RANK/RANKL antagonists comprising a soluble RANK
polypeptide may include other portions of RANK besides the
extracellular domain but do not include the transmembrane
region.
[0020] In some embodiments, fusion proteins comprising a soluble
RANK for use as antagonists suitable for the methods described
herein are those described in U.S. Patent Publication 2003/0021785
A1, which is incorporated here in full by reference.
[0021] In some embodiments, soluble RANK polypeptides suitable for
the methods described herein can be those described in U.S. Patent
Publication 2003/0021785 A1, which is incorporated here in full by
reference.
[0022] In some embodiments, soluble RANK proteins for use as
antagonists suitable for the methods described herein are those
described in U.S. Patent Publication 2003/0021785 A1, which is
incorporated here in full by reference.
[0023] The terms "OPG" or "osteoprotegerin" or "OPG receptor"
include their common meaning in the field and includes "native
sequence OPG polypeptides" and "OPG variants" (which are further
defined herein). "OPG" can be a designation given to those
polypeptides which can be encoded by the nucleic acid molecules
comprising the polynucleotide sequences shown in Simonet et al.,
Cell, 89:309 (1997) and variants thereof, as well as fragments of
any of the sequences referred to above. The OPG polypeptides may be
isolated from a variety of sources, such as from human tissue or
cells or from another source, or prepared by recombinant and/or
synthetic methods. A "native sequence" OPG polypeptide includes its
common meaning in the field and additionally includes the
following: comprises a polypeptide having the same amino acid
sequence as the corresponding OPG polypeptide derived from nature.
Such native sequence OPG polypeptides can be isolated from nature
or can be produced by recombinant and/or synthetic means. The term
"native sequence OPG polypeptide" includes its common meaning in
the field and additionally includes the following: specifically
encompasses naturally-occurring truncated or secreted forms (e.g.,
an extracellular domain sequence), naturally-occurring variant
forms (e.g., alternatively spliced forms) and naturally-occurring
allelic variants of the polypeptide. The OPG polypeptides include
the polypeptides described as "FDCR-1" and "OCIF" in Yasuda et al.,
Endocrinology, 139:1329 (1998) and Yun et al., J. Immunol., 1 61:61
13-6121 (1998).
[0024] "OPG variant" includes its common meaning in the field and
includes an OPG polypeptide having at least about 80% amino acid
sequence identity with the amino acid sequence of a native sequence
OPG or OPG ECD. In some embodiments, the OPG variant binds to
RANKL, such as, to the full length RANK Ligand.
[0025] An "extracellular domain" or "ECD" include their common
meaning in the field and include: a form of the polypeptide which
is essentially free of the transmembrane and cytoplasmic domains.
Ordinarily, an ECD form of a polypeptide will have less than about
1% of such transmembrane and/or cytoplasmic domains and possibly,
will have less than about 0.5% of such domains. It can be
understood that any transmembrane domain(s) identified for the
polypeptides can be identified pursuant to criteria routinely
employed in the art for identifying that type of hydrophobic
domain. The exact boundaries of a transmembrane domain may vary. In
some embodiments, the boundaries of a transmembrane domain varies
by no more than about 5 amino acids at either end of the domain as
initially identified. In some embodiments, the ECD will consist of
a soluble, extracellular domain sequence of the polypeptide which
is free of the transmembrane and cytoplasmic or intracellular
domains (and is not membrane bound).
[0026] A "liposome" includes its common meaning in the field and
includes: a small vesicle composed of various types of lipids,
phospholipids and/or surfactant which can be useful for delivery of
a drug (such as a polypeptide or antibody thereto) to a mammal. The
components of the liposome can be commonly arranged in a bilayer
formation, similar to the lipid arrangement of biological
membranes.
[0027] The term "antibody" includes its common meaning in the field
and includes use in the broadest sense, and additionally,
specifically covers, for example, single monoclonal antibodies
which can bind RANKL or RANK, antibody compositions with
polyepitopic specificity, single chain antibodies, and fragments of
antibodies.
[0028] Some RANK/RANKL antagonists may comprise an antibody, such
as a monoclonal antibody.
[0029] The term "monoclonal antibody" as used herein includes its
common meaning in the field and includes: an antibody obtained from
a population of substantially homogeneous antibodies, i.e., the
individual antibodies comprising the population can be identical
except for possible naturally occurring mutations that may be
present in minor amounts. Monoclonal antibodies can be highly
specific, being directed against a single antigenic site.
Furthermore, in contrast to conventional (polyclonal) antibody
preparations which typically include different antibodies directed
against different determinants (epitopes), each monoclonal antibody
can be directed against a single determinant on the antigen. In
addition to their specificity, the monoclonal antibodies can be
advantageous in that they can be synthesized by hybridoma culture,
uncontaminated by other immunoglobulins. The modifier "monoclonal"
includes its common meaning in the field and 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 may be made by the hybridoma
method first described by Kohler et al., Nature, 256:495 (1975), or
may be made by recombinant DNA methods (see, e.g., U.S. Pat. No.
4,816,567). The "monoclonal antibodies" may also be isolated from
phage antibody libraries using the techniques described in Clackson
et al., Nature, 352:624-628 (1991) and Marks et al., J. Mol. Biol.,
222:581-597 (1991), for example.
[0030] The monoclonal antibodies herein specifically include
"chimeric" antibodies (immunoglobulins) which includes its common
meaning in the field and includes: a portion of the heavy and/or
light chain can be identical to or homologous with 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) can be identical to or homologous with
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 (U.S. Pat. No. 4,816,567; Morrison et al.,
Proc. Natl. Acad. Sci. USA, 81:6851-6855 (1984)). Methods of making
chimeric antibodies are known in the art.
[0031] "Humanized" forms of non-human (e.g., murine) antibodies can
be chimeric immunoglobulins, immunoglobulin chains or fragments
thereof (such as Fv, Fab, Fab', F(ab').sub.2 or other
antigen-binding subsequences of antibodies) which contain minimal
sequence derived from non-human immunoglobulin. For the most part,
humanized antibodies can be human immunoglobulins (recipient
antibody) in which residues from a complementarity-determining
region (CDR) of the recipient can be replaced by residues from a
CDR of a non-human species (donor antibody) such as mouse, rat or
rabbit having the desired specificity, affinity, and capacity. In
some instances, Fv framework region (FR) residues of the human
immunoglobulin can be replaced by corresponding non-human residues.
Furthermore, humanized antibodies may comprise residues which can
be found neither in the recipient antibody nor in the imported CDR
or framework sequences. These modifications can be made to further
refine and maximize 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 CDR regions correspond to those of a non-human
immunoglobulin and all or substantially all of the FR regions can
be those of a human immunoglobulin sequence. The humanized antibody
optimally also will comprise at least a portion of an
immunoglobulin constant region (Fc), typically that of a human
immunoglobulin. For further details, see Jones et al., Nature,
321:522-525 (1986); Reichmann et al., Nature, 332:323-329 (1988);
and Presta, Curr. Op. Struct. Biol., 2:593-596 (1992). The
humanized antibody may be an antibody wherein the antigen-binding
region of the antibody can be derived from an antibody produced by
immunizing macaque monkeys with the antigen of interest. Methods of
making humanized antibodies are known in the art.
[0032] Human antibodies can also be produced using various
techniques known in the art, including phage-display libraries.
Hoogenboom and Winter, J. Mol. Biol., 227:381 (1991); Marks et al.,
J. Mol. Biol., 222:581 (1991). The techniques of Cole et al. and
Boerner et al. are also available for the preparation of human
monoclonal antibodies. Cole et al., Monoclonal Antibodies and
Cancer Therapy, Alan R. Liss, p. 77 (1985); Boerner et al., J.
Immunol., 147(1):86-95 (1991).
[0033] "Antibody fragments" comprise a portion of an intact
antibody, such as the antigen binding or variable region of the
intact antibody. Examples of antibody fragments include Fab, Fab',
F(ab').sub.2, and Fv fragments; diabodies; linear antibodies
(Zapata et al., Protein Eng. 8(10): 1057-1062); single-chain
antibody molecules; and multispecific antibodies formed from
antibody fragments. Papain digestion of antibodies produces two
identical antigen-binding fragments, called "Fab" fragments, each
with a single antigen-binding site, and a residual "Fc" fragment, a
designation reflecting the ability to crystallize readily. Pepsin
treatment yields an F(ab').sub.2 fragment that has two
antigen-combining sites and can be still capable of cross-linking
antigen.
[0034] "Fv" can be the minimum antibody fragment which contains a
complete antigen-recognition and binding site. This region consists
of a dimer of one heavy- and one light-chain variable domain in
tight, non-covalent association. It can be in this configuration
that the three CDRs of each variable domain interact to define an
antigen-binding site on the surface of the V.sub.H-V.sub.L dimer.
Collectively, the six CDRs confer antigen-binding specificity to
the antibody. However, even a single variable domain (or half of an
Fv comprising only three CDRs specific for an antigen) has the
ability to recognize and bind antigen, although at a lower affinity
than the entire binding site. The Fab fragment also contains the
constant domain of the light chain and the first constant domain
(CH1) of the heavy chain. Fab fragments differ from Fab' fragments
by the addition of a few residues at the carboxy terminus of the
heavy chain CH1 domain including one or more cysteines from the
antibody hinge region. Fab'-SH is the designation herein for Fab'
in which the cysteine residue(s) of the constant domains bear a
free thiol group. F(ab').sub.2 antibody fragments originally were
produced as pairs of Fab' fragments which have hinge cysteines
between them. Other chemical couplings of antibody fragments are
also known.
[0035] The "light chains" of antibodies (immunoglobulins) from any
vertebrate species can be assigned to one of two clearly distinct
types, called kappa and lambda, based on the amino acid sequences
of their constant domains.
[0036] Depending on the amino acid sequence of the constant domain
of their heavy chains, immunoglobulins can be assigned to different
classes. There are five known major classes of immunoglobulins:
IgA, IgD, IgE, IgG, and IgM, and several of these may be further
divided into subclasses (isotypes), e.g., IgG1, IgG2, IgG3, IgG4,
IgA, and IgA2.
[0037] "Single-chain Fv" or "sFv" antibody fragments comprise the
V.sub.H and V.sub.L domains of antibody, wherein these domains are
present in a single polypeptide chain. The Fv polypeptide further
comprises a polypeptide linker between the V.sub.H and V.sub.L
domains which can enable the sFv to form the desired structure for
antigen binding. For a review of sFv, see Pluckthun in The
Pharmacology of Monoclonal Antibodies, vol. 1 13, Rosenburg and
Moore eds., Springer-Verlag, New York, pp. 269-315 (1994).
[0038] The term "diabodies" includes its common meaning in the
field and includes: small antibody fragments with two
antigen-binding sites, which fragments comprise a heavy-chain
variable domain (V.sub.H) connected to a light-chain variable
domain (V.sub.L) in the same polypeptide chain (V.sub.H-V.sub.L).
By using a linker that is too short to allow pairing between the
two domains on the same chain, the domains can be forced to pair
with the complementary domains of another chain and create two
antigen-binding sites. Diabodies are described more fully in, for
example, EP 404,097; WO 93/011161; and Hollinger et al., Proc.
Natl. Acad. Sci. USA, 90:6444-6448 (1993). An antibody that
"specifically binds to" or can be "specific for" a particular
polypeptide or an epitope on a particular polypeptide can be one
that binds to that particular polypeptide or epitope on a
particular polypeptide without substantially binding to any other
polypeptide or polypeptide epitope.
[0039] In some embodiments, the RANKL antagonist can be an OPG
(osteoprotegerin) variant or an anti-RANKL antibody; the RANKL
antagonist can be a monoclonal anti-RANKL antibody; the RANKL
antagonist can be a humanized monoclonal anti-RANKL antibody; the
RANKL antagonist can be denosumab; or the RANKL antagonist can be
OPG.
[0040] In some embodiments, the RANK/RANKL antagonist can be
denosumab. Denosumab is a fully human antibody that shares the
pharmacological attributes of OPG, in that both bind to and inhibit
RANKL. Additionally, denosumab can have a significant longer
half-life than OPG, allowing less frequent administration. In some
embodiments, the RANK/RANKL antagonist can be OPG. Further
description of denosumab may be found in WO 2013/181575 A2, which
is incorporated here in full by reference.
[0041] In some embodiments, the RANK/RANKL antagonist can be an OPG
(osteoprotegerin) variant or an anti-RANKL antibody. In some
embodiments, the RANK/RANKL antagonist can be a monoclonal
anti-RANKL antibody. In some embodiments, the RANK/RANKL antagonist
can be a small interfering RNA, a microRNA, a precursor molecule, a
ribozyme, an antisense nucleic acid sequence, or an aptamer
targeting RANKL. In some embodiments, the RANK/RANKL antagonist can
be a humanized monoclonal anti-RANKL antibody.
[0042] In some embodiments, the nucleic acid molecules encoding a
soluble RANK for use as a RANK/RANKL antagonist suitable for the
methods described herein are those described in U.S. Patent
Publication 2003/0021785 A1, which is incorporated here in full by
reference.
[0043] In some embodiments, antisense RNA and DNA molecules for use
as antagonists suitable for the methods described herein are those
described in U.S. Patent Publication 2003/0021785 A1, which is
incorporated here in full by reference.
[0044] Small interfering RNA (short interfering RNA, silencing RNA,
sRNA) can be a class of double-stranded RNA-molecules, which can be
19-30 nucleotides, such as 20-25 nucleotides long. siRNAs inhibit
expression of a specific gene via RNA-interference. siRNAs can be
cut from long double-stranded RNAs by the RNase III Dicer. They can
also be derived by chemical synthesis. They also play a role in
antiviral mechanisms or in shaping the chromatin structure of a
genome. In molecular research, synthetic siRNAs can also be used in
RNA-interference (RNAi) to downregulate the expression of specific
target genes. With their ability to knock down essentially any gene
of interest, siRNAs can been used to knock down RANK or RANKL.
MicroRNAs (miRNAs) can be posttranscriptional regulators that bind
to complementary sequences in the 3'UTR of mRNA transcripts,
usually resulting in gene silencing. They can be short RNA
molecules which can be about 22 nucleotides long.
[0045] Precursor molecules, e.g. precursor molecules of sRNA and/or
miRNA, may be substrates for the sRNA/miRNA-biogenesis-apparatus of
the target cell. This comprises, for example, RNA precursor
molecules such as double-stranded RNA (dsRNA) or short hairpin
RNA-molecules (shRNA), which can be processed by endonucleases such
as Drosha and/or Pasha to sRNA molecules or miRNA molecules,
respectively. In some embodiments, dsRNA-molecules or short hairpin
RNA-molecules (shRNA) having a length of more than 27 nucleotides,
more than 30 up to 100 nucleotides or longer, or dsRNA molecules
having a length of 30-50 nucleotides, can be used.
[0046] Further precursor molecules may be DNA constructs encoding
dsRNA, shRNA, siRNA and/or miRNA, whereby the coding elements can
be controlled by regulatory elements allowing an expression of
dsRNA, shRNA, siRNA, and/or miRNA in the target cell. Examples for
such control elements can be polymerase II or promoters or
polymerase III promoters such as, for example, U6 or H1. Ribozymes
can be catalytic RNAs which possess a well defined structure that
enables them to catalyze a chemical reaction. Apart from naturally
occurring ribozymes they can be made artificially and be tailored
to interact with nucleic acids and proteins.
[0047] Antisense oligonucleotides can be single strands of DNA or
RNA that can be complementary to a chosen sequence. They can be
between 10 and 35 nucleotides long, such as about 20-25
nucleotides. Antisense DNA oligonucleotides can target specific,
complementary RNA, and upon binding DNA/RNA hybrids can be formed.
Antisense RNA oligonucleotides can bind to mRNA by binding to mRNA
strands.
[0048] Aptamers can be oligonucleic acid (DNA or RNA aptamers) or
peptide molecules (peptide aptamers) that bind to a specific target
molecule. Aptamers can be used for therapeutic purposes as
macromolecular drugs. Aptamers can be created by selecting them
from a large random sequence pool.
[0049] A RANK/RANKL antagonist can be a small molecule, e.g. a
compound that is not a biomolecule, such as a compound having a
molecular weight below about 2000, Daltons, 1000 Daltons, or 500
Daltons.
[0050] Some Bruton's tyrosine kinase (BTK) inhibitors can be
RANK/RANKL antagonists. BTK is primarily expressed in B cells,
myeloid and erythroid progenitor cells.
[0051] BTK inhibitors can include ONO-4059; ibrutinib;

[0064] Generally, an oral dosage form comprising a small molecule
RANK/RANKL antagonist such as ibrutinib, zoledronic acid, or
minodronic acid, can be administered orally to a mammal, such as a
human being, at least once, to treat a disease or condition, or to
relieve pain
[0065] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,

inflammatory pain, arthritis pain, complex regional pain syndrome,
lumbosacral pain, musculoskeletal pain, neuropathic pain, chronic
pain, cancer-related pain, acute pain, postoperative pain,
fibromyalgia, etc. In some instances, pain relief may be
palliative, or pain relief may be provided independent of
improvement of the disease or condition or the underlying cause of
the disease or condition. For example, although the underlying
disease may not improve, or may continue to progress, an individual
suffering from the disease may experience pain relief. In some
embodiments, enhanced bioavailability of the zoledronic acid or
minodronic acid may be achieved in treating one of these conditions
by administering a dosage form comprising zoledronic acid in the
form of a disodium salt. This may allow a reduced molar amount of
the disodium salt to be used as compared to what would be used with
the diacid form.
[0066] In some embodiments, the RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may be administered to relieve
inflammatory pain including musculoskeletal pain, arthritis pain,
and complex regional pain syndrome.
[0067] In some embodiments, a RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may be administered orally to
relieve inflammatory pain including musculoskeletal pain, arthritis
pain, and complex regional pain syndrome.
[0068] With respect to use of a RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, for relieving pain associated
with an inflammatory condition or musculoskeletal pain, relief of
pain can be short-term, e.g. for a period of hours after
administration of the dosage form, and/or relief of pain can be
long-term, e.g. lasting for days, weeks, or even months after
administration of the RANK/RANKL antagonist. In some embodiments, a
mammal, such as a human being, experiences pain relief at least
about 3 hours, at least about 6 hours, at least about 12 hours, at
least about 24 hours, at least about 48 hours, at least about one
week, at least about 2 weeks, or at least about 3 weeks, at least
about 1 month, at least about 2 months, at least about 3 months, at
least about 6 months, after administration of denosumab, minodronic
acid, or oral zoledronic acid. In some embodiments, a mammal, such
as a human being, experiences pain relief during at least part of
the time from about 3 hours to about 2 weeks, about 3 hours to

[0069] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may be administered to relieve musculoskeletal
pain including back pain (such as low back pain), and pain
associated with rheumatoid arthritis, juvenile rheumatoid
arthritis, osteoarthritis, erosive osteoarthritis, sero-negative
(non-rheumatoid) arthropathies, non-articular rheumatism,
peri-articular disorders, axial spondyloarthritis including
ankylosing spondylitis, Paget's disease of bone, fibrous dysplasia,
SAPHO syndrome, transient osteoarthritis of the hip, vertebral
crush fractures, osteoporosis, etc.
[0070] Examples of musculoskeletal pain include back pain (such as
low back pain); and pain associated with vertebral crush fractures,
fibrous dysplasia, osteogenesis imperfecta, Paget's disease of
bone, transient osteoporosis, and transient osteoporosis of the
hip.
[0071] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may also be used to treat bone fractures or to
enhance the healing of bone fractures.
[0072] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may also be used to treat low back pain, or
other musculoskeletal or inflammatory conditions, having a change
in bone that is detectable by MRI or another medical imaging
instrument. For example, a RANK/RANKL antagonist may be used to
treat low back pain associated Modic changes, or vertebral endplate
signal changes (VESC) and bone marrow changes visible using
magnetic resonance imaging (MRI). Modic changes, can be classified
into various types including type 1 (M1), type 2 (M2), and type 3

RANK/RANKL antagonist. VESCs may be found in patients with
different types of low back pain including but not limited to
spondylitis, trauma, spondyloarthropathies including ankylosing
spondylitis, Schmorl's nodes, fracture, tumor, and spinal cord
infarction. Lesions in ankylosing spondylitis include osteitis and
spondylodiscitis which can be detected using MRI or another medical
imaging instrument. Treatment with a RANK/RANKL antagonist, such as
an antibody (e.g. denosumab) or an oral or intravenous small
molecule (such as ibrutinib, zoledronic acid, or minodronic acid)
may reduce the size of, or prevent the growth or progression of
changes in bone that are detectable on MRI (e.g. Modic changes,
VESC, bone marrow changes, bone marrow edema, etc.).
[0073] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may also be used to treat arthritis. Arthritis
refers to inflammatory joint diseases that can be associated with
pain. Examples of arthritis pain include pain associated with
osteoarthritis, erosive osteoarthritis, rheumatoid arthritis,
juvenile rheumatoid arthritis, psoriatic arthritis, sero-negative
(non-rheumatoid) arthropathies, non-articular rheumatism,
peri-articular disorders, neuropathic arthropathies including
Charcot's foot, axial spondyloarthritis including ankylosing
spondylitis, and SAPHO syndrome.
[0074] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may also be used to treat arthritis, such as
osteoarthritis of the knee, including arthritis or osteoarthritis
of the knee associated with bone marrow lesions (BML), including
BML that may be detected using MRI or another medical imaging
instrument. In some embodiments, a RANK/RANKL antagonist may be
used to treat arthritis or osteoarthritis of the knee associated
with bone marrow edema (BME), including BME which may be detected
using MRI or another medical imaging instrument.
[0075] In some embodiments, a human being that is treated for a
disease or condition, such as an inflammatory condition, e.g.
arthritis, with a RANK/RANKL antagonist, has an age of about 10
years to about 90 years, about 20 years to about 80 years, about 30
years to about 75 years, about 40 years to about 70 years, about 1
year to about 16 years, or about 80 years to about 95 years.
[0076] In some embodiments, a human being that is treated for a
disease or condition, such as an inflammatory condition or
musculoskeletal pain, e.g. arthritis, with a RANK/RANKL antagonist,
has suffered from the disease or condition for at least 1 month, at
least 2 months, at least 6 months, or at least 1 year.
[0077] In some embodiments, the disease or condition, such as an
inflammatory condition, e.g. arthritis, affects a knee, an elbow, a
finger, a toe, a wrist, a shoulder, or a hip.
[0078] In some embodiments, the RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may also be administered to
relieve neuropathic pain, including diabetic peripheral neuropathy,
post-herpetic neuralgia, trigeminal neuralgia, monoradiculopathies,
phantom limb pain, and central pain. Other causes of neuropathic
pain include cancer-related pain, lumbar nerve root compression,
spinal cord injury, post-stroke pain, central multiple sclerosis
pain, HIV-associated neuropathy, and radio-therapy or chemo-therapy
associated neuropathy. In some embodiments, enhanced
bioavailability of the zoledronic acid may be achieved in treating
one of these conditions by administering a dosage form comprising
zoledronic acid in the form of a disodium salt. This may allow a
reduced molar amount of the disodium salt to be used as compared to
what would be used with the diacid form.
[0079] In some embodiments, administration of a RANK/RANKL
antagonist, such as an antibody (e.g., denosumab), or a small

may also be useful to treat hypercalcemia of malignancy, multiple
myeloma, bone metastases from solid tumors, Paget's disease of
bone, giant cell tumor of bone, blood cancers or leukemias, or
solid tumors or cancers.
[0080] In some embodiments, the mammal being treated may not be
suffering from bone metastasis. In some embodiments, the mammal
being treated may not be suffering from cancer. In some
embodiments, the mammal being treated may not be suffering from
osteoporosis. In some embodiments, if the mammal has osteoporosis
or cancer, the mammal is being treated for pain that is not a
result of osteoporosis or cancer. In some embodiments, if the
mammal has osteoporosis or cancer, a second therapeutic agent is
administered to the mammal for the treatment of osteoporosis or
cancer, and wherein the second therapeutic agent is not a
RANK/RANKL antagonist.
[0081] A RANK/RANKL antagonist, such as an antibody (e.g.,
denosumab), or a small molecule such as ibrutinib, zoledronic acid,
or minodronic acid, may also be administered to relieve
cancer-related pain, including pain associated with multiple
myeloma and bone metastases from solid tumors. In some embodiments,
a RANK/RANKL antagonist is used to treat pain that may not be
cancer-related pain. For example, a RANK/RANKL antagonist may be
used to treat pain that may not be associated with multiple
myeloma, bone metastasis from solid tumors, hypercalcemia of
malignancy, giant cell tumor of bone, blood cancers or leukemias,
or solid tumors or cancers. In some embodiments, enhanced
bioavailability of zoledronic acid or minodronic acid may be
achieved in treating one of these conditions by administering a
dosage form comprising zoledronic acid or minodronic acid in the
form of a disodium salt. This may allow a reduced molar amount of
the disodium salt to be used as compared to what would be used with
the diacid form.
[0082] In some embodiments, a RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may be administered to relieve
complex regional pain syndrome, such as complex regional pain
syndrome type I (CRPS-I), complex regional pain syndrome type II
(CRPS-II), CRPS-NOS, or another type of CRPS. CRPS is a type of
inflammatory pain. CRPS can also have a neuropathic component.
[0083] Complex regional pain syndrome is a debilitating pain
syndrome. It is characterized by severe pain in a limb accompanied
by edema, and autonomic, motor and sensory changes.
[0084] In some embodiments, a RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may be administered to treat
fibromyalgia. Fibromyalgia is a condition which may affect the
muscles and soft tissue, and may include symptoms in the head,
back, neck, shoulder, and/or hip.
[0085] In some embodiments, a RANK/RANKL antagonist, such as an
antibody (e.g., denosumab), or a small molecule such as ibrutinib,
zoledronic acid, or minodronic acid, may also be useful to treat
complex regional pain syndrome, rheumatoid arthritis,
osteoarthritis, erosive osteoarthritis, axial spondyloarthritis
including ankylosing spondylitis, acute vertebral crush fracture,
fibrous dysplasia, SAPHO syndrome, osteoporosis, transient
osteoporosis, or transient osteoporosis of the hip. In some
embodiments, enhanced bioavailability of zoledronic acid or
minodronic acid may be achieved in treating one of these conditions
by administering a dosage form comprising zoledronic acid or
minodronic acid in the form of a disodium salt. This may allow a
reduced molar amount of the disodium salt to be used as compared to
what would be used with the diacid form.
[0086] In some embodiments, administration a RANK/RANKL antagonist,
such as an antibody (e.g., denosumab) or an oral small molecule
(such as ibrutinib, zoledronic acid, or minodronic acid) may also
be useful to treat hypercalcemia of malignancy, multiple myeloma,
bone metastases from solid tumors, Paget's disease of bone, giant
cell tumor of bone, blood cancers or leukemias, or solid tumors or
cancers. In some embodiments, enhanced bioavailability of
zoledronic acid or minodronic acid may be achieved in treating one
of these conditions by administering a dosage form comprising
zoledronic acid or minodronic acid in the form of a disodium salt.
This may allow a reduced molar amount of the disodium salt to be
used as compared to what would be used with the diacid form.
[0087] With respect to the treatment of any condition recited
herein, in some embodiments a first dose of the RANK/RANKL
antagonist is administered and a second dose of the RANK/RANKL
antagonist is administered. The timing of the administration of the
two doses may be such that, with respect to the first dose, the
second dose with respect to the first dose, the second dose is
administered at 5.times.T.sub.max or greater (e.g., if T.sub.max is
1 hour, at 5 hours or later), at least 10.times.T.sub.max or
greater, at least about 15.times.T.sub.max or greater, at least
about 20.times.T.sub.max or greater, at least about
50.times.T.sub.max or greater, or at least about
200.times.T.sub.max or greater, wherein T.sub.max is the time of
maximum plasma concentration for the first dose.
[0088] Some embodiments include treatment of a condition recited
herein, such as musculoskeletal pain, inflammatory pain, arthritis,
or complex regional pain syndrome, wherein the treatment comprises
either: administering only one dose or dosage form to a mammal to
treat the condition, or administering a first dose or dosage form
to the mammal (e.g. orally), followed by administering a second
dose or dosage form to the mammal (e.g. orally). If two or more
doses or dosage forms are administered, the second dose or dosage
form is administered before the maximum pain relieving effect of
the first dose or dosage form is achieved, or before a peak in the
pain relieving effect of the first dose or dosage form is
experienced by a mammal, receiving the dose or dosage form. In some
embodiments, the second dose or dosage form is administered before
an observable pain relieving effect is achieved. In some
embodiments, the second dose or dosage form is administered about
12 hours to about 60 days, about 24 hours to about 28 days, about
24 hours to about 7 days, about 24 hours to about 14 days, or about
24 hours to about 21 days, after the first dose or dosage form is
administered.
[0089] Some embodiments include treatment of a condition recited
herein, such as musculoskeletal pain, inflammatory pain, arthritis,
or complex regional pain syndrome, wherein the treatment comprises
administering a first dose or dosage form, such as a first oral
dosage form, to the mammal, followed by administering a second dose
or dosage form, such as a second oral dosage form, to the mammal,
wherein the second dose or dosage form is administered after the
maximum pain relieving effect of the first dose or dosage form is
achieved, and the second dose or dosage form is administered while
the mammal is still experiencing pain relief from the first dose or
dosage form, or while the pain relieving effect from the first dose
or dosage form is observable. In some embodiments, the second dose
or dosage form is administered about 12 hours to about 60 days,
about 24 hours to about 28 days, about 24 hours to about 7 days,
about 24 hours to about 14 days, or about 24 hours to about 21
days, after the first dose or dosage form is administered.
[0090] In addition to relieving pain, administration of a
RANK/RANKL antagonist, such as an antibody (e.g., denosumab), or a
small molecule such as ibrutinib, zoledronic acid, or minodronic
acid, may also be useful to treat diseases or conditions that may
or may not include a pain component. For example, a RANK/RANKL
antagonist may be useful to treat any of the pain conditions or
types of conditions listed above, including treatment that does not
simply relieve the pain of those conditions, and treatment that is
carried out in such a way that the condition is treated without
pain relief occurring. In addition to any pain relief a RANK/RANKL
antagonist may or may not provide, a RANK/RANKL antagonist may be
used to treat a disease or condition such as a metabolic disease or
condition; an inflammatory disease or condition, including an
inflammatory disease or condition that might not be associated with
pain; a cancer disease or condition; a neurological disease or
condition; etc.
[0091] The duration of treatment will vary depending upon the
particular RANK/RANKL antagonist, the disease or condition being
treated, and other factors. For biological molecules such as
denosumab repeated doses may be administered over at least a period
of two weeks or longer, or may be administered indefinitely.
Several rounds of treatment may be given, alternating with periods
of no treatment. If discontinued, treatment may be resumed if a
relapse of the pain should occur.
[0092] For therapeutic use, a RANK/RANKL antagonist can be
administered to a mammal, including a human patient, for treatment
in a manner appropriate to the indication. Systemic administration
may be used. The RANK/RANKL antagonist may be applied locally. For
biological molecules such as denosumab, means of local
administration include, for example, local injection, or
application of the antagonist admixed or polymerized with a
slow-release matrix suitable for this purpose, many of which can be
known.
[0093] In some embodiments, RANK/RANKL antagonists can be
concurrently administered with other drugs or therapeutic agents in
the manufacture of a medicament for the treatment of pain.
RANK/RANKL antagonists and other drugs may be formulated into
therapeutic compositions comprising an effective amount of the
antagonist.
[0094] In some embodiments, therapeutic agents that may be
administered in conjunction with the RANK/RANKL antagonists
described herein may include therapeutic agents indicated for the
treatment of pain or another neurological disorder. In some
embodiments, therapeutic agents indicated for the treatment of pain
and/or inflammation may include analgesic and/or anti-inflammatory
agents, including aspirin (acetylsalicylic acid), nonsteroidal
anti-inflammatory drugs (NSAIDs) (e.g., ibuprofen, naproxen,
ketoprofren, celecoxib, firocoxib, meloxicam, etc.), acetaminophen,
narcotic or opioid pain relievers (e.g., morphine, codeine,
fentanyl, oxycodone, hydrocodone, hydromorphone, etc.), and
steroids (e.g., triamcinolone, predisone, methylprednisolone,
cortisone, etc.).
[0095] In some embodiments, sustained-release forms of RANK/RANKL
antagonists can be used. Sustained-release forms suitable for use
in the disclosed methods include, but are not limited to, soluble
RANK polypeptides, and antagonistic anti-RANK or anti-RANKL
antibodies that can be encapsulated in a slowly-dissolving
biocompatible polymer (such as the alginate microparticles
described in U.S. Pat. No. 6,036,978), admixed with a slow-release
polymer (including topically applied hydrogels), and/or
incorporated into a biocompatible semi-permeable implant.
[0096] The amount of RANK/RANKL antagonist administered per dose
will vary depending on the antagonist being used and the mode of
administration. If the antagonist is a soluble RANK and is
administered by injection, the effective amount per adult dose will
range from about 0.5 mg/m.sup.2 to about 20 mg/m.sup.2, about 1
mg/m.sup.2 to about 5 mg/m.sup.2, about 3 mg/m.sup.2 to about 10

Alternatively, a flat dose may be administered, whose amount may
range from 5 mg/dose to about 100 mg/dose, about 5 mg/dose to 50
mg/dose, about 10 mg/dose to 60 mg/dose, about 15 mg/dose to about
45 mg/dose, about 50 mg/dose to about 100 mg/dose, about 20 mg/dose
to about 70 mg/dose, about 30 mg/dose to about 75 mg/dose, about 25
mg/dose to about 50 mg/dose, or any dose in between or bounded by
these ranges. Some dose ranges for a flat dose to be administered
by subcutaneous injection can be 5 mg/dose to about 25 mg/dose, 25
mg/dose to about 50 mg/dose, about 15 mg/dose to about 30 mg/dose,
about 45 mg/dose to about 70 mg/dose, about 60 mg/dose to about 80
mg/dose, about 1 mg/dose to about 20 mg/dose, about 30 mg/dose to
about 60 mg/dose, or about 50 mg/dose to about 100 mg/dose. The
chosen dose may be administered repeatedly, particularly for
chronic conditions, or the amount per dose may be increased or
decreased as treatment progresses. The chosen dose may be
administered one or more times per week, monthly, every two months,
every three months, every six months, or every year.
[0097] For pediatric patients (ages 4-17), a suitable regimen
involves the subcutaneous injection of 0.4 mg/kg, up to a maximum
dose of 25 mg or more, about 0.1 mg/kg to about 10 mg/kg, about 5
mg/kg to about 15 mg/kg, about 10 mg/kg to about 25 mg/kg, about 10
mg/kg to about 17 mg/kg, about 12 mg/kg to about 20 mg/kg, about 15
mg/kg to about 25 mg/kg, or about 15 mg/kg to about 40 mg/kg, to be
administered one or more times per week, monthly, every two months,
every three months, every six months, or every year. If an antibody
against RANK or RANKL is used as the RANK/RANKL antagonist, useful
dose ranges include about 0.1 mg/kg to about 20 mg/kg, about 0.75
mg/kg to about 7.5 mg/kg and about 1 mg/kg to about 10 mg/kg of
body weight. The chosen dose may be administered repeatedly,
particularly for chronic conditions, or the amount per dose may be
increased or decreased as treatment progresses. The chosen dose may
be administered one or more times per week, monthly, every two
months, every three months, every six months, or every year.
[0098] Useful doses for an antibody against RANK or RANKL, such as
denosumab, may range from about 0.1 mg/kg to about 20 mg/kg, about
0.75 mg/kg to about 7.5 mg/kg, about 0.1 mg/kg to about 5 mg/kg,
about 1 mg/kg to about 2 mg/kg, about 10 mg/kg to about 20 mg/kg,
about 12 to about 17 mg/kg, about 15 mg/kg to about 20 mg/kg, about
1 mg/kg, about 1 mg/kg to about 10 mg/kg, or any value bounded by
or in between these ranges based on the body weight of the mammal.
The chosen dose may be administered repeatedly, particularly for
chronic conditions, or the amount per dose may be increased or
decreased as treatment progresses. The chosen dose may be
administered one or more times per week, monthly, every two months,
every three months, every six months, or every year.
[0099] Doses of the antagonist may be administered daily, weekly,
monthly, every three months, every six months, or every year. Doses
may be administered in single or divided doses. In some
embodiments, humanized antibodies are used, that is, antibodies in
which only the antigen-binding portion of the antibody molecule is
derived from a non-human source. Antibodies may be administered by
injection, including intravenous infusion. Appropriate dosages can
be determined in trials. The amount and frequency of administration
will depend, of course, on such factors as the nature and severity
of the indication being treated, the desired response, the
condition of the patient, and so forth.

[0106] A monthly dose, such as the monthly oral dose, may be given
as a single dose, or as two or more individual doses administered
during the month. In some embodiments, the monthly dose, such as
the monthly oral dose, can be administered in 1, 2, 3, 4, 5, 6, 7,
8, 9, or 10 individual doses during the month. In some embodiments,
the monthly dose, such as the monthly oral dose, can be
administered in 2 or 3 weekly doses. In some embodiments, the
monthly dose, such as the monthly oral dose, can be administered in
4 or 5 weekly doses. In some embodiments, the monthly dose, such as
the monthly oral dose, can be administered in 28 to 31 daily doses.
In some embodiments, the monthly dose, such as the monthly oral
dose, can be administered in 5 to 10 individual doses during the
month. The monthly dose, such as the monthly oral dose, may be
administered for only 1 month, or may be repeatedly administered
for 2, 3, 4, 5, 6 or more months.
[0107] The RANK/RANKL antagonists may be administered orally,
parenterally, sublingually, by inhalation spray, rectally, or
topically in dosage unit formulations containing conventional
nontoxic pharmaceutically acceptable carriers, adjuvants, and
vehicles as desired. Topical administration may also involve the
use of transdermal administration such as transdermal patches or
ionophoresis devices. Injection can be a route of administration
that may be used, including parenteral injection. Parenteral
injections include subcutaneous injections, intraspinal,
intrathecal, intraorbital, intravenous, intrarterial,
intramuscular, intrasternal, and infusion techniques. Compositions
comprising a RANK/RANKL antagonist can be administered by bolus
injection or continuous infusion. Routes of systemic administration
that may be used include subcutaneous injection and intravenous
drip.
[0108] Pharmaceutical compositions suitable for parenteral
administration (e.g., by injection, for example bolus injection or
continuous infusion) and may be presented in unit dose form in
ampoules, pre-filled syringes, small volume infusion 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, obtained by aseptic
isolation of sterile solid or by lyophilization from solution, for
constitution with a suitable vehicle, e.g., sterile, pyrogen-free
water, before use.
[0109] With respect to oral administration of zoledronic acid or
minodronic acid for the treatment of pain associated with
inflammation, arthritis, CRPS, or any other condition recited
herein, it may helpful if the mammal or human being to which the
zoledronic acid is administered does not eat food or drink
beverage, (other than any water required to swallow the oral dosage
form) for at least about 1 hour, at least about 2 hours, at least
about 4 hours, at least about 6 hours, at least about 8 hours, at
least about 10 hours, or at least about 12 hours before the
zoledronic acid is administered. It may also be helpful if the
mammal or human being to which the zoledronic acid is administered
does not eat food or drink beverage for at least about 30 minutes,
at least about 1 hour, at least about 2 hours, at least about 3
hours, or at least about 4 hours after the zoledronic acid is
administered. In some embodiments, a human being to which the
zoledronic acid is administered avoids lying down, or remains
upright or sits upright, for at least about 30 minutes or about 1
hour after receiving a dosage form containing zoledronic acid.
Avoiding food or beverage before or after oral administration of
zoledronic acid can improve the bioavailability of the zoledronic
acid.
[0110] The effective amount of zoledronic acid or minodronic acid
will vary depending on various factors known to the treating
physicians, such as the severity of the condition to be treated,
route of administration, formulation and dosage forms, and age,
weight and response of the individual patients.
[0111] RANK/RANKL antagonists and other drugs may be formulated
into therapeutic compositions comprising an effective amount of the
antagonist.
[0112] Some embodiments include a pharmaceutical composition
comprising a purified soluble protein having RANK/RANKL
antagonistic activity, in conjunction with physiologically
acceptable carriers, excipients or diluents. Such carriers may be
nontoxic to recipients at the dosages and concentrations employed.
Inhibitors of the RANK/RANKL interaction for pharmaceutical
compositions can be complexed with polyethylene glycol (PEG), metal
ions, or incorporated into polymeric compounds such as polyacetic
acid, polyglycolic acid, hydrogels, dextran, etc., or incorporated
into liposomes, microemulsions, micelles, unilamellar or
multilamellar vesicles, erythrocyte ghosts or spheroblasts.
[0113] Protein complexes with PEG can be made using known
procedures, such as for example, those described in U.S. Pat. No.
5,849,860, U.S. Pat. No. 5,766,897 or other suitable methods.
Suitable lipids for liposomal formulation include, without
limitation, monoglycerides, diglycerides, cholesterol, sulfatides,
lysolecithin, phospholipids, saponin, bile acids, and the like.
Preparation of liposomal formulations is within the level of skill
in the art, as disclosed, for example, in U.S. Pat. No. 4,235,871;
U.S. Pat. No. 4,501,728; U.S. Pat. No. 4,837,028; U.S. Pat. No.
4,737,323; and U.S. Pat. No. 5,858,397. Such compositions will
influence the physical state, solubility, stability, rate of in
vivo release, and rate of in vivo clearance, and can be thus chosen
according to the intended application, so that the characteristics
of the carrier will depend on the selected route of
administration.
[0114] Ordinarily, the preparation of pharmaceutical compositions
comprising a RANK/RANKL antagonist that is a protein entails
combining the therapeutic protein with buffers, antioxidants such
as ascorbic acid, low molecular weight (less than about 10
residues) polypeptides, proteins, amino acids, carbohydrates
including glucose, sucrose or dextrins, chelating agents such as
EDTA, glutathione and other stabilizers and excipients. Neutral
buffered saline or saline mixed with conspecific serum albumin can
be exemplary appropriate diluents. In certain embodiments, the
product can be formulated as a lyophilizate using appropriate
excipient solutions (e.g., sterile water or sucrose solution) as
diluents. One embodiment entails packaging a lyophilized RANK/RANKL
antagonist in dose unit form which when reconstituted will provide
one to three doses per package.
[0115] In one aspect at least one RANK/RANKL antagonist or a
pharmaceutically acceptable salt thereof or composition comprising
same can be used in combination with another therapy indicated for
pain or other neurological disorders.
[0116] Small molecule RANK/RANKL antagonists, including ibrutinib,
zoledronic acid, and minodronic acid, may be formulated for oral
administration, for example, with an inert diluent or with an
edible carrier, or it may be enclosed in hard or soft shell gelatin
capsules, compressed into tablets, or incorporated directly with
the food of the diet. For oral therapeutic administration, the
active compound may be incorporated with an excipient and used in
the form of ingestible tablets, buccal tablets, coated tablets,
troches, capsules, elixirs, dispersions, suspensions, solutions,
syrups, wafers, patches, and the like.
[0117] Tablets, troches, pills, capsules and the like may also
contain one or more of the following: a binder such as gum
tragacanth, acacia, corn starch or gelatin; an excipient, such as
dicalcium phosphate; a disintegrating agent such as corn starch,
potato starch, alginic acid and the like; a lubricant such as
magnesium stearate; a sweetening agent such as sucrose, lactose or
saccharin; or a flavoring agent such as peppermint, oil of
wintergreen or cherry flavoring. When the unit dosage form is a
capsule, it may contain, in addition to materials of the above
type, a liquid carrier. Various other materials may be present as
coating, for instance, tablets, pills, or capsules may be coated
with shellac, sugar or both. A syrup or elixir may contain the
active compound, sucrose as a sweetening agent, methyl and
propylparabens as preservatives, a dye and flavoring, such as
cherry or orange flavor. It may be desirable for material in a
dosage form or pharmaceutical composition to be pharmaceutically
pure and substantially non toxic in the amounts employed.
[0118] Some compositions or dosage forms may be a liquid, or may
comprise a solid phase dispersed in a liquid.
[0119] Zoledronic acid may be formulated for parenteral or
intraperitoneal administration. Solutions of the active compounds
as free acids or pharmacologically acceptable salts can be prepared
in water suitably mixed with a surfactant, such as
hydroxypropylcellulose. A dispersion can also have an oil dispersed
within, or dispersed in, glycerol, liquid polyethylene glycols, and
mixtures thereof. Under ordinary conditions of storage and use,
these preparations may contain a preservative to prevent the growth
of microorganisms.
[0120] In some embodiments, sustained-release forms of RANK/RANKL
antagonists can be used. Sustained-release forms suitable for use
in the disclosed methods include, but are not limited to, soluble
RANK polypeptides, and antagonistic anti-RANK or anti-RANKL
antibodies that can be encapsulated in a slowly-dissolving
biocompatible polymer (such as the alginate microparticles
described in U.S. Pat. No. 6,036,978), admixed with a slow-release
polymer (including topically applied hydrogels), and/or
incorporated into a biocompatible semi-permeable implant.
[0121] The amount of the RANK/RANKL antagonist, such as denosumab,
or a small molecule such as ibrutinib, zoledronic acid, or
minodronic acid, in a therapeutic composition may vary. For
example, some liquid compositions may comprise about 0.0001% (w/v)
to about 50% (w/v), about 0.01% (w/v) to about 20% (w/v), about
0.01% to about 10% (w/v), about 0.001% (w/v) to about 1% (w/v),
about 0.1% (w/v) to about 0.5% (w/v), about 1% (w/v) to about 3%
(w/v), about 3% (w/v) to about 5% (w/v), about 5% (w/v) to about 7%

15% (w/v), about 15% (w/v) to about 20% (w/v), about 20% (w/v) to
about 30% (w/v), about 30% (w/v) to about 40% (w/v), or about 40%
(w/v) to about 50% (w/v) of the RANK/RANKL antagonist.
[0122] Some solid compositions may comprise at least about 5%
(w/w), at least about 10% (w/w), at least about 20% (w/w), at least
about 50% (w/w), at least about 70% (w/w), at least about 80%,
about 10% (w/w) to about 30% (w/w), about 10% (w/w) to about 20%
(w/w), about 20% (w/w) to about 30% (w/w), about 30% (w/w) to about
50% (w/w), about 30% (w/w) to about 40% (w/w), about 40% (w/w) to
about 50% (w/w), about 50% (w/w) to about 80% (w/w), about 50%
(w/w) to about 60% (w/w), about 70% (w/w) to about 75% (w/w), about
70% (w/w) to about 80% (w/w), or about 80% (w/w) to about 90% (w/w)
of a RANK/RANKL antagonist such as a ibrutinib, zoledronic acid, or
minodronic acid.
[0123] Any suitable amount of RANK/RANKL antagonist, such as
denosumab, ibrutinib, zoledronic acid, or minodronic acid, may be
used. Some solid or liquid oral dosage forms, or units of oral
dosage forms (referred to collectively herein as "oral dosage

any amount of RANK/RANKL antagonist in a range bounded by, or
between, any of these values. In some embodiments, the RANK/RANKL
antagonist can be administered daily, weekly, monthly, every two or
three months, once a year, or twice a year.
[0124] In some embodiments, an oral dosage form may contain about

expressed in mg/m.sup.2 can be based upon the body surface area of
the mammal.
[0125] Oral zoledronic acid, or disodium salt thereof, may be
administered in combination with about 0.1 mg to about 10 mg of
zoledronic acid, or a salt thereof, administered parenterally, such
as intravenously. In some embodiments, about 50 mg, about 100 mg,
or about 150 mg of the disodium salt of zoledronic acid can be
administered orally in combination with 1 mg parenteral, such as
intravenous, zoledronic acid. In some embodiments the parenteral
dose of zoledronic acid can be about 0.25 mg to about 25 mg, about
0.25 mg to about 10 mg, or about 0.5 mg to about 7.5 mg.
[0126] The oral bioavailability of zoledronic acid or minodronic
acid may be enhanced by orally administering the zoledronic acid or
minodronic acid in the disodium salt form.
[0127] For example, the bioavailability of zoledronic acid may be
improved by at least about 10%, at least about 20%, at least about
30%, at least about 50%, and/or up to about 100%, or up to about
200%, as compared to administration of zoledronic acid in the
diacid form.
[0128] Similarly, the bioavailability of minodronic acid may be
improved by at least about 10%, at least about 20%, at least about
30%, at least about 50%, and/or up to about 100%, or up to about
200%, as compared to administration of minodronic acid in the
diacid form.
[0129] Because of the improved bioavailability of the disodium salt
a dosage form may contain, or a mammal, such as a human being, may
receive, on a molar basis, less of the disodium salt form of
zoledronic acid or minodronic acid than would otherwise be
administered of the diacid form of zoledronic acid.
[0130] For example, a dosage form may contain, or a mammal may
receive, at least about 10 mole % less, at least about 20 mole %
less, at least about 40 mole % less, at least about 50 mole % less,
and/or up to about 90 mole % less or 95 mole % less, of the
disodium salt form as compared the amount of the diacid form of
zoledronic acid that would otherwise be administered, such as a
molar amount that would be administered of zoledronic acid in the
diacid form in order to achieve the same plasma levels of
zoledronic acid.
[0131] Similarly, a dosage form may contain, or a mammal may
receive, at least about 10 mole % less, at least about 20 mole %
less, at least about 40 mole % less, at least about 50 mole % less,
and/or up to about 90 mole % less or 95 mole % less, of the
disodium salt form as compared the amount of the diacid form of
minodronic acid that would otherwise be administered, such as a
molar amount that would be administered of minodronic acid in the
diacid form in order to achieve the same plasma levels of
minodronic acid.
[0132] In some embodiments, a dosage form contains, or a mammal
(such as a human being) can be administered, an amount of the
disodium salt form, on a molar basis, that has a value of about
0.8n.sub.d to about 1.2n.sub.d or about 0.9n.sub.d to about
1.1n.sub.d, wherein:
n.sub.d=(b.sub.a/b.sub.d)(n.sub.a)
wherein b.sub.a is the bioavailability of the diacid form, b.sub.d
is the bioavailability of the disodium salt form, and n.sub.a is
the number of moles of the diacid that would be administered in a
dosage form containing the diacid form of zoledronic acid. For
example, if the diacid form has a bioavailability (b.sub.a) of 0.01
and the disodium salt form has a bioavailability (b.sub.d) of
0.015, and a dosage form would normally contain 0.001 moles of the
diacid, n.sub.d would be (0.01/0.015)(0.001 moles), or about
0.00067 moles. In some embodiments, the disodium salt can be
administered in an amount that has a value of about n.sub.d.
[0133] With respect to oral dosage forms comprising a reduced molar
amount of the disodium salt of zoledronic acid as compared to the
diacid form of zoledronic acid, in some embodiments, the
bioavailability of the zoledronic acid in the disodium salt form
can be sufficiently high that, if the drug is administered to a
mammal, at least as much zoledronic acid is present in the blood of
the mammal as would be present if zoledronic acid were administered
in the diacid form.
[0134] With respect to oral dosage forms comprising the disodium
salt form of zoledronic acid, in some embodiments, the disodium
salt form can be present in a lower molar amount than would be
present if the zoledronic acid were in the diacid form; and the
zoledronic acid in the disodium salt form has an improved
bioavailability as compared to the zoledronic acid in the diacid
form to the extent that the lower molar amount of the disodium salt
in the dosage form does not reduce the amount of zoledronic acid
delivered to the plasma of a mammal.
[0135] In some embodiments, the zoledronic acid in the disodium
salt form can be present in an amount such that the oral dosage
form provides an area under the plasma concentration curve of
zoledronic acid of about 4 ngh/mL to about 2000 ngh/mL to the
mammal each time the zoledronic acid in the disodium salt is
administered.
[0136] In some embodiments, the zoledronic acid in the disodium
salt form is present in an amount such that the oral dosage form
provides an area under the plasma concentration curve of zoledronic
acid of about 100 ngh/mL to about 2000 ngh/mL, about 100 ngh/mL to
about 1000 ngh/mL, about 500 ngh/mL to about 1000 ngh/mL, or about
500 ngh/mL to about 700 ngh/mL in the mammal to which the dosage
form is administered. This amount may be suitable for
administration of the oral dosage form about every 3 to 4
weeks.
[0137] In some embodiments, the zoledronic acid in the disodium
salt form can be present in an amount such that the oral dosage
form provides an area under the plasma concentration curve of
zoledronic acid of about 20 ngh/mL to about 700 ngh/mL, about 50
ngh/mL to about 500 ngh/mL, or about 100 ngh/mL to about 200
ngh/mL, in the mammal to which the dosage form is administered.
This amount may be suitable for weekly administration of the oral
dosage, or for administration of 3 to 5 individual dosages during a
month. The individual dosages could be given at regular intervals,
given during the first week, or at any other schedule that provides
3 to 5 dosages during the month.
[0138] In some embodiments, the zoledronic acid in the disodium
salt form can be present in an amount such that the oral dosage
form provides an area under the plasma concentration curve of
zoledronic acid of about 4 ngh/mL to about 100 ngh/mL, about 10
ngh/mL to about 50 ngh/mL, or about 10 ngh/mL to about 30 ngh/mL,
in the mammal to which the dosage form is administered. This amount
may be suitable for daily administration of the oral dosage
form.
[0139] Oral administration of zoledronic acid, particularly oral
administration of the disodium salt form of zoledronic acid, can
result in more sustained plasma levels of the drug as compared to
parenteral modes of administration, such intravenous or
subcutaneous. For example, the amount of zoledronic acid in the
plasma can be significantly higher for oral administration of the
disodium salt about 24 hours or 48 hours, or longer, after
administration. In some embodiments, oral zoledronic acid has a 24
hour sustained plasma level factor of about 1 or higher, such as
about 1 to about 10, about 1 to about 5, about 3 to about 5, or
about 3 to about 4. In some embodiments, an orally administered
dosage form of zoledronic acid has a 24 hour sustained plasma level
factor or a 48 hour sustained plasma level factor that can be
higher, such as at least 1.2 times, at least about 2 times, at
least about 5 times, about 1.2 times to about 20 times, about 2
times to about 15 times, about 5 times to about 10 times, or about
8 to about 15 times that of intravenously administered zoledronic
acid. A "sustained plasma level factor," p.sub.f, can be determined
by the equation:
p.sub.f=1000(C.sub.t/C.sub.max)
wherein C.sub.max is the maximum plasma concentration of zoledronic
acid after it is administered and C.sub.t is the plasma
concentration of zoledronic acid at the time of interest, such as
24 hours. For parenteral administration, the C.sub.max can be about
the C.sub.0, or the concentration right after injection of the
entire amount of the drug into the body. Sustained plasma level
factors can also be obtained for other times, such as 48 hours, by
using the plasma concentration of zoledronic acid for C.sub.t in
the equation above. For example, if the maximum plasma level of
zoledronic acid after administration is 1000 ng/mL and the plasma
level of zoledronic acid at 24 hours is 1 ng/mL, the 24 hour
sustained plasma level factor is 1.
[0140] In some embodiments, the disodium salt form of zoledronic
acid provides an enhancement to bioavailability, as compared to the
diacid form of zoledronic acid, which adds to any enhancement to
bioavailability provided by any bioavailability-enhancing agents in
the dosage form. In some embodiments, the disodium salt form of
zoledronic acid provides an enhancement to bioavailability, as
compared to the diacid form of zoledronic acid, which is greater
than any enhancement to bioavailability provided by any
bioavailability-enhancing agents in the dosage form. In some
embodiments, the disodium salt form of zoledronic acid may be
administered in a dosage form that is substantially free of
bioavailability-enhancing agents.
[0141] In some embodiments, a dosage form comprising a disodium
salt of zoledronic acid is a solid.
[0142] In some embodiments, a dosage form comprising a disodium
salt of zoledronic acid can be used to treat an inflammatory
condition.
[0143] In some embodiments, a dosage form comprising a disodium
salt of zoledronic acid can be used to treat arthritis.
[0144] In some embodiments, a dosage form comprising a disodium
salt of zoledronic acid can be used to treat complex regional pain
syndrome.
[0145] In some embodiments, zoledronic acid can be in a form that
has an aqueous solubility, meaning the solubility in water, greater
than 1% (w/v), about 5% (w/v) to about 50% (w/v), about 5% (w/v) to
about 20% (w/v), about 10% (w/v) to about 15% (w/v), or about 12%
(w/v) to about 13% (w/v).
[0146] The disodium salt form of zoledronic acid can be more
compressible than the diacid form of zoledronic acid. This can make
it easier for a dosage form to have a desired hardness. It can also
make it easier to increase the drug load, so that a smaller tablet
can be given for a given dosage strength. In some embodiments, a
solid dosage form of zoledronic acid, such as the diacid form of
zoledronic acid or the disodium salt form of zoledronic acid, can
have a hardness of about 5 kPa to about 20 kPa or about 5 kPa to
about 14 kPa.
[0147] The oral bioavailability of zoledronic acid in a dosage form
can vary. Some dosage forms may have ingredients added to enhance
the bioavailability. However, bioavailability enhancement might not
be necessary for an oral dosage form to be effective. In some
embodiments, the dosage form can be substantially free of
bioavailability-enhancing agents. In some embodiments, an oral
dosage form may have an oral bioavailability of zoledronic acid of
about 0.01% to about 10%, about 0.1% to about 7%, about 0.1% to
about 5%, etc. Without ingredients or other methods to enhance
bioavailability, zoledronic acid typically has a low
bioavailability in an oral dosage form. In some embodiments, the
oral bioavailability of zoledronic acid can be unenhanced or
substantially unenhanced. For example, the oral bioavailability of
zoledronic acid can be about 0.01% to about 5%, about 0.01% to
about 4%, about 0.1% to about 3%, about 0.1% to about 2%, about
0.2% to about 2%, about 0.2% to about 1.5%, about 0.3% to about
1.5%, about 0.3% to about 1%, about 0.1% to about 0.5%, about 0.3%
to about 0.5%, about 0.5% to about 1%, about 0.6% to about 0.7%,
about 0.7% to about 0.8%, about 0.8% to about 0.9%, about 0.9%,
about 1% to about 1.1%, about 1.1% to about 1.2%, about 1.2% to
about 1.3%, about 1.3% to about 1.4%, about 1.4% to about 1.5%,
about 1.5% to about 1.6%, about 1.6% to about 1.8%, or about 1.8%
to about 2%.
[0148] One embodiment is a pharmaceutical composition comprising
zoledronic acid wherein the oral bioavailability of zoledronic acid
in the dosage form is from about 0.01% to about 10%, about 0.01% to
about 5%, about 0.1% to about 7%, about 0.1% to about 5%, about
0.1% to about 3%, about 0.1% to about 2%, about 0.2% to about 2%,
about 0.2% to about 1.5%, about 0.3% to about 1.5%, about 0.3% to
about 1.0%, about 1% to about 2.5%, about 1.2% to about 2.5%, about
1.5% to about 2.5%, about 1% to about 2.7%, about 1.2% to about
2.7%, about 1.5% to about 2.7%, about 1% to about 3%, about 1.2% to
about 3%, about 1.5% to about 3%, about 1% to about 3.5%, about
1.2% to about 3.5%, about 1.5% to about 3.5%.
[0149] An oral dosage form comprising zoledronic acid or minodronic
acid may be included in a pharmaceutical product comprising more
than one unit of the oral dosage form.
[0150] In some embodiments, an oral dosage form comprises about 10
mg to about 300 mg of zoledronic acid, and can be administered
daily for about 2 to about 15 consecutive days. This regimen may be
repeated once monthly, once every two months, once every three
months, once every four months, once every five months, once every
six months, once yearly, or once every two years.
[0151] In some embodiments, an oral dosage form comprises about 10
mg to about 150 mg or about 10 mg to about 100 mg of zoledronic
acid, and can be administered daily for about 2 to about 15
consecutive days. This regimen may be repeated once monthly, once
every two months, once every three months, once every four months,
once every five months, once every six months, once yearly, or once
every two years.
[0152] In some embodiments, an oral dosage form comprises about 10
mg to about 150 mg or about 10 mg to about 100 mg of zoledronic
acid, and can be administered daily for about 5 to about 10
consecutive days. This regimen may be repeated once monthly, once
every two months, once every three months, once every four months,
once every five months, once every six months, once yearly, or once
every two years.
[0153] In some embodiments, an oral dosage form comprises about 40
mg to about 150 mg of zoledronic acid, and can be administered
daily for about 5 to about 10 consecutive days. This regimen may be
repeated once monthly, once every two months, once every three
months, once every four months, once every five months, once every
six months, once yearly, or once every two years.
[0154] In some embodiments, the oral zoledronic acid may be
administered as one dose of about 100 mg to about 2000 mg. In some
embodiments, the oral zoledronic acid may be administered as one
dose of about 300 mg to about 1500 mg. In some embodiments, the
oral zoledronic acid may be administered as one dose of about 200
mg to about 1000 mg. The dose of zoledronic acid may be
administered in a single or divided dose.
[0155] A pharmaceutical product containing oral dosage forms for
daily use can contain 28, 29, 30, or 31 units of the oral dosage
form for a monthly supply. An approximately 6 week daily supply can
contain 40 to 45 units of the oral dosage form. An approximately 3
month daily supply can contain 85 to 95 units of the oral dosage
form. An approximately six-month daily supply can contain 170 to
200 units of the oral dosage form. An approximately one year daily
supply can contain 350 to 380 units of the oral dosage form.
[0156] A pharmaceutical product containing oral dosage forms for
weekly use can contain 4 or 5 units of the oral dosage form for a
monthly supply. An approximately 2 month weekly supply can contain
8 or 9 units of the oral dosage form. An approximately 6 week
weekly supply can contain about 6 units of the oral dosage form. An
approximately 3 month weekly supply can contain 12, 13 or 14 units
of the oral dosage form. An approximately six-month weekly supply
can contain 22 to 30 units of the oral dosage form. An
approximately one year weekly supply can contain 45 to 60 units of
the oral dosage form.
[0157] A pharmaceutical product may accommodate other dosing
regimes. For example, a pharmaceutical product may comprise 5 to 10
units of the oral dosage form, wherein each unit of the oral dosage
form contains about 40 mg to about 150 mg of zoledronic acid. Some
pharmaceutical products may comprise 1 to 10 units of the oral
dosage form, wherein the product contains about 200 mg to about
2000 mg of zoledronic acid. For such a product, each unit of the
oral dosage form may be taken daily for 1 to 10 days or 5 to 10
days during a month, such as at the beginning of a month.
[0158] Some oral dosage forms comprising zoledronic acid or a salt
thereof may have enteric coatings or film coatings.

[0160] In the examples below, zoledronic acid was used to produce
RANK/RANKL antagonism.
EXAMPLES
Example 1
Effect of RANK/RANKL Antagonism in Rat Model of Inflammatory
Pain
Method:
[0161] Inflammatory pain was induced by injection of 100% CFA in a
75 .mu.L volume into the left hind paws of SPRAGUE DAWLEY.RTM. rats
on day 0, followed by assessments on days 1-4. Animals were orally
administered 3 mg/kg zoledronic acid (or 18 mg/m.sup.2) to produce
RANK/RANKL antagonism, or vehicle (control). Drug was dissolved in
distilled water and prepared fresh daily. Animals were fasted prior
to dosing.
[0162] Values for inflammatory pain (mechanical hyperalgesia) in
the vehicle and drug-treated animals were obtained on day 0 prior
to CFA injection, and at baseline and post-treatment on days 1-4.
Pain was assessed using a digital Randall-Selitto device (dRS; IITC
Life Sciences, Woodland Hills, Calif.). Animals were placed in a
restraint sling that suspended the animal, leaving the hind limbs
available for testing. Paw compression threshold was measured by
applying increasing pressure to the plantar surface of the hind paw
with a dome-shaped tip placed between the 3rd and 4th metatarsus.
Pressure was applied gradually over approximately 10 seconds.
Measurements were taken from the first observed nocifensive
behavior of vocalization, struggle or withdrawal. A cut-off value
of 300 g was used to prevent injury to the animal.
[0163] Reversal of inflammatory pain was calculated according to
the formula:
% reversal=(Post-treatment-Post-CFA baseline)/(Pre-CFA
baseline-Post-CFA baseline).times.100
[0164] Total Pain Relief (TOTPAR), for the 24 hours following
vehicle or drug administration, was calculated as the area under
the pain relief (reversal of inflammatory pain) versus time curve,
as described in U.S. Patent Publication 2014/0107210, using the
linear trapezoidal rule. Values for total pain relief were
quantified as %hr, or the product of reversal of inflammatory pain
(%) and time (hr).
[0165] The experiment was carried out using 9-10 animals per
group.
Results:
[0166] RANK/RANKL antagonism with zoledronic acid significantly
improved inflammatory pain thresholds compared to vehicle. Pain
threshold measurements taken at various times are shown in FIG. 1.
Paw compression thresholds were higher than for vehicle during the
entire measurement period after 30 minutes from the start of
treatment.
[0167] RANK/RANKL antagonism resulted in greater 24-hour Total Pain
Relief than that achieved with vehicle treatment on all dosing days
as shown in FIG. 2.
Example 2
Effect of RANK/RANKL Antagonism in Rat Model of Arthritis Pain
Method:
[0168] The effect of RANK/RANKL antagonism on arthritis pain was
examined in the rat complete Freund's adjuvant (CFA) model of
arthritis pain. In this model, injection of 100% complete Freund's
adjuvant (CFA) in a 75 .mu.L volume into the left hind paws is
followed by a 10-14 day period to allow for the development of
arthritis pain. Animals were orally administered zoledronic acid 9
mg/kg (or 54 mg/m.sup.2), or zoledronic acid 60 mg/kg (or 360
mg/m.sup.2) to produce RANK/RANKL antagonism, divided in three
equal daily doses on the first three days post CFA injection, or
vehicle (control). The drug was dissolved in distilled water and
prepared fresh daily. Animals were fasted prior to dosing.
[0169] Arthritis pain (mechanical hyperalgesia) in the vehicle and
drug-treated animals was evaluated on day 14 post CFA injection
using a digital Randall-Selitto device (dRS; IITC Life Sciences,
Woodland Hills, Calif.). Animals were placed in a restraint sling
that suspended the animal, leaving the hind limbs available for
testing. Paw compression threshold was measured by applying
increasing pressure to the plantar surface of the hind paw with a
dome-shaped tip placed between the 3rd and 4th metatarsus. Pressure
was applied gradually over approximately 10 seconds. Measurements
were taken from the first observed nocifensive behavior of
vocalization, struggle or withdrawal. A cut-off value of 300 g was
used to prevent injury to the animal.
[0170] Reversal of arthritis pain in the ipsilateral (CFA-injected)
paw was calculated according to the formula:
% reversal=(ipsilateral drug threshold-ipsilateral vehicle
threshold)/(contralateral vehicle threshold-ipsilateral vehicle
threshold).times.100
[0171] The experiment was carried out using 7-10 animals per
group.
Results:
[0172] RANK/RANKL antagonism with zoledronic acid significantly
improved arthritis pain thresholds compared to vehicle. As shown in
FIGS. 3 and 4, RANK/RANKL antagonism produced a dose-dependent
reversal of arthritis pain. A reversal of 33% was observed in the 9
mg/kg group, and reversal of 54% was observed in the 60 mg/kg
group.
Example 3
Effect of RANK/RANKL Antagonism in Complex Regional Pain Syndrome
(CRPS)
[0173] The effect of RANK/RANKL antagonism was examined in the rat
tibia fracture model of complex regional pain syndrome (CRPS). CRPS
was induced in the rats by fracturing the right distal tibias of
the animals and casting the fractured hindpaws for 4 weeks, as
described in Guo T Z et al. (Pain. 2004; 108:95-107). This animal
model has been shown to replicate the inciting trauma, natural
history, signs, symptoms, and pathologic changes observed in human
CRPS patients (Kingery W S et al., Pain. 2003; 104:75-84).
[0174] The casts were removed on the 28th day after fracture.
Starting on day 29, animals were orally administered either
zoledronic acid to produce RANK/RANKL antagonism, or vehicle, for 3
weeks. Drug treated animals received zoledronic acid at a dose of
21 mg/kg (126 mg/m.sup.2) on the first day (day 29), followed by 3
mg/kg/day (18 mg/m.sup.2/day) thereafter. Drug was dissolved in
distilled water and administered by gavage. Animals were fasted for
4 hours before and 2 hours after dosing. Bilateral testing of
hindpaw pain was performed at baseline, on day 29 after fracture,
and then weekly for three weeks.
[0175] To measure pain (hyperalgesia), an up-down von Frey testing
paradigm was used. Rats were placed in a clear plastic cylinder (20
cm in diameter) with a wire mesh bottom and allowed to acclimate
for 15 minutes. The paw was tested with one of a series of eight
von Frey hairs ranging in stiffness from 0.41 g to 15.14 g. The von
Frey hair was applied against the hindpaw plantar skin at
approximately midsole, taking care to avoid the tori pads. The
fiber was pushed until it slightly bowed and then it was jiggled in
that position for 6 seconds. Stimuli were presented at an interval
of several seconds. Hindpaw withdrawal from the fiber was
considered a positive response. The initial fiber presentation was
2.1 g and the fibers were presented according to the up-down method
of Dixon to generate six responses in the immediate vicinity of the
50% threshold. Stimuli were presented at an interval of several
seconds.
[0176] Reversal of CRPS pain in the fracture hindpaw was calculated
according to the formula:
% reversal=(change in pain threshold from baseline to 4 weeks
post-fracture-change in pain threshold from baseline to timepoint
after treatment start)/(change in pain threshold from baseline to 4
weeks post-fracture).times.100.
[0177] The experiment was carried out in 6 animals per group. As
illustrated in FIG. 5, RANK/RANKL antagonism with zoledronic acid
significantly reversed CRPS pain as compared to vehicle treatment.
Three weeks after dosing RANK/RANKL antagonism resulted in a
complete reversal of CRPS pain.
