thereby treating the subject with glaucoma.
DETAILED DESCRIPTION OF THE INVENTION
As shown herein, increased expression of TNF-.alpha. and its receptor in
the glaucomatous optic nerve head and retina demonstrate a role of this
cytokine in the neurodegenerative process of glaucoma, which provides a
novel therapeutic target for the management of glaucoma.
This invention provides a method for treating a subject with glaucoma by
administrating a composition containing an agent or molecule which
antagonizes, inhibits, inactivates, reduces, suppresses, antagonizes,
and/or limits the release, synthesis, or production from cells of TNF-.alpha.
thereby treating the subject with glaucoma.

This indicates a significant role of TNF-.alpha. in the neurodegenerative
process seen in glaucoma, drugs inhibiting its function are an attractive
targets to decrease cell death in glaucoma. In addition, since TNF-.alpha.
is a stimulator of nitric oxide synthesis (Romero L I, Tatro J B, Field J

inhibitors, inactivators, reducers, supressors, or agents which
antagonize, and/or limits the release, synthesis, or production from cells
of TNF-.alpha. reduce nitric oxide synthase-2 expression and activity

overexpression in rheumatoid arthritis patients treated with anti-tumor
necrosis factor monoclonal antibody (cA2). Arth Rheum.
1998,41:2205-2210.). Therefore, blockade, amelioration or attentuation of
TNF-.alpha. is also effective on inhibiting, reducing or preventing nitric
oxide synthase-related cell death which is known as an important mediator
of neuronal cell death, and may be a causal factor in glaucoma (Neufeld
AH, Sawada A, Becker B. inhibition of nitric-oxide synthase 2 by
aminoguanidine provides neuroprotection of retinal ganglion cells in a rat
model of chronic glaucoma Proc Natl Acad Sci USA Aug. 17, 1999
;96(17):9944-8)
The type of glaucoma for which the invention is applicable includes but is
not limited to: primary open angle glaucoma, normal pressure glaucoma,
pigmentary glaucoma, pseudoexfoliation glaucoma, acute angle closesure
glaucoma, absolute glaucoma chronic glaucoma, congenital glaucoma,
juvenile glaucoma, narrow angle glaucoma, chronic open angle glaucoma and
simplex glaucoma.
As provided herein, the Tumor Necrosis Factor (TNF) superfamily of
cytokines includes both soluble and membrane-bound proteins that regulate
cellular activation (including immune responses and inflammatory
reactions), cellular viability and proliferation, NF-kappa B activation,
and also the pathology of various diseases. TNF-.alpha. is a cytokine
produced by macrophages and lymphocytes which mediates inflammatory and
immunopathological responses. TNF-.alpha. has been implicated in the
progression of diseases which include but are not limited to
immunomodulation disorder, infection, cell proliferation, angiogenesis (neovascularisation),
tumour metastasis, apoptosis, sepsis, and endotoxaemia The necrotising
action of TNF in vivo mainly relates to capillary injury. TNF causes
necrosis not only in tumour tissue but also in granulation tissue. It
causes morphological changes in growth inhibition of and cytoxicity
against cultured vascular endothelial cells (Haranka et al 1987 Ciba Found
Symp 131: 140-153).
Expression of TNF receptors on both lymphoid and non-lymphoid cells can be
influenced experimentally by many different agents, such as bacterial
lipopolysaccharide (LIPS), phorbol myristate acetate (PMA; a protein
kinase C activator), interleukin-1 (IL-1), interferon-gamma (IFN-.gamma.)
and IL-2 (Gatanaga et al. Cell Immuno/. 138:1-10, 1991; Yui et al.
Placenta 15:819-835, 1994). It has been shown that complexes of human TNF
bound to its receptor are internalized from the cell membrane, and then
the receptor is either degraded or recycled (Armitage, Curr. Opin. Immunol.
6:407-413, 1994). TNF receptor activity can be modulated using peptides
that bind intracellularly to the receptor, or which bind to he ligand
binding site, or that affect receptor shedding. See for example patent
publications WO 95/31544, WO 95/33051, WO 96/01642, and EP 568 925.
TNF binding proteins (TNF-BP) have been identified at elevated levels in
the serum and urine of febrile patients, patients with renal failure, and
cancer patients, and even certain healthy individuals. Human brain and
ovarian tumors produced high serum levels of TNF-BP These molecules have
been purified, characterized, and cloned (Gatanaga et al., Lymphokine Res.
9:225-229, 1990a; Gatanaga et al., Proc. Nat/. Acad. Sci USA 87:8781-8784,
1990b). Humun TNF-BP consists of 30 kDa and 40 kDa proteins which are
identical to the N-terminal extracellular domains of p55 and p75 TNF
receptors, respectively (U.S. Pat. No. 5,395,760; EP 418,014). Such
proteins have been suggested for use in treating endotoxic shock. Mohler
et al. J. Immunol. 151: 1548-1561, 1993 There are several mechanisms
possible for the production of secreted proteins resembling membrane bound
receptors. One involves translation from alternatively spliced mRNAs
lacking transmembrane and cytoplasmic regions.
A "TNF modulator" is a compound that has the property of either increasing
or decreasing TNF activity for processing TNF on the surface of cells.
Etanercept (Brand name Embrel) is known to those skilled in the art.
Etanercept is a recombinant form of the human tumor necrosis factor
receptor fused to the Fc fragment of a human IgG1 molecule. The resulting
form is a dimeric molecule that can bind two circulating tumor necrosis
factor (TNF) molecules. This binding prevents TNF from interacting with
the cell surface TNF receptors, inhibiting its role in the joint
pathology. Currently there are two TNF receptors that have been identified
p75 and p55) and both have the same affinity for TNF. Etanercept is
supplied in a carton containing four dose trays; each tray contains one 25
mg single-use vial of etanercept, one syringe (1 mL Sterile Bacteriostatic
Water for Injection, USP containing 0.9% benzyl alcohol), one plunger, and
2 alcohol swabs. The recommended dose of etanercept for adult patients is
25 mg given twice weekly as a subcutaneous injection.
Infliximab (Remicade) is known to those skilled in the art. Infliximab (Remicade)
is a chimeric IgG1K monoclonal antibody produced by a recombinant
cell line to treat Crohn's disease. Infliximab (Remicade) acts by
neutralizing the biological activity of TNF{character pullout} by
high-affinity binding to its soluble and transmembrane forms and inhibits
TNF{character pullout} receptor binding.
Homolog means a polypeptides having the same or conserved residues at a
corresponding position in their primary, secondary or tertiary structure.
The term also extends to two or more nucleotide sequences encoding the
homologous polypeptides.
A "nucleic acid" or "polynucleotide" refers to the phosphate ester
polymeric form of ribonucleosides (adenosine, guanosine, uridine or
cytidine; "RNA molecules") or deoxyribonucleosides (deoxyadenosine,
deoxyguanosine, deoxythymidine, or deoxycytidine; "DNA molecules") in
either single stranded form, or a double-stranded helix. Double stranded
DNA-DNA, DNA-RNA and RNA-RNA helices are possible. The term nucleic acid
molecule, and in particular DNA or RNA molecules, refers only to the
primary and secondary structure of the molecule, and does not limit it to
any particular tertiary forms. Thus, this term includes double-stranded
DNA found, inter alia, in linear or circular DNA molecules (e.g.,
restriction fragments), plasmids, and chromosomes. In discussing the
structure of particular double-stranded DNA molecules, sequences may be
described herein according to the normal convention of giving only the
sequence in the 5' to 3' direction along the nontranscribed strand of DNA
(i.e., the strand having a sequence homologous to the mRNA). A
"recombinant DNA" is a DNA that has undergone a molecular biological
manipulation.
"Substantial identity" or "substantial sequence identity" mean that two
sequences, when optimally aligned, such as by the programs GAP or BESTFIT
using default gap which share at least 65-99 percent sequence identity,
share at least 75 percent sequence identity, share at least 80 percent
sequence identity, share at least 90 percent sequence identity, preferably
at least 95 percent sequence identity, more preferably at least 99 percent
sequence identity or more. The following terms are used to describe the
sequence relationships between two or more nucleic acid molecules or
polynucleotides: "reference sequence", "comparison window", "sequence
identity", "percentage of sequence identity", and "substantial identity".
A "reference sequence" is a defined sequence used as a basis for a
sequence comparison; a reference sequence may be a subset of a larger
sequence, for example, as a segment of a full-length cDNA or gene sequence
given in a sequence listing or may comprise a complete cDNA or gene
sequence.
Optimal alignment of sequences for aligning a comparison window may be
conducted by the local homology algorithm of Smith and Waterman (1981)
Adv. Appl. Math 2:482, by the homology alignment algorithm of Needleman
and Wunsch (1970) J. Mol. Biol. 48:443, by the search for similarity
method of Pearson and Lipman (1988) Proc. Natl. Acad. Sci. (USA) 85:2444,
or by computerized implementations of these algorithms (GAP, BESTFIT,
FASTA, and TFASTA in the Wisconsin Genetics Software Package Release 7.0,
Genetics Computer Group, 575 Science Dr., Madison, Wis.).
The terms "polypeptide", "peptide" and "protein" are used interchangeably
herein to refer to polymers of amino acids of any length The polymer may
be linear or branched, it may comprise modified amino acids, and it may be
interrupted by non-amino acids. The terms also encompass an amino acid
polymer that has been modified; for example, disulfide bond formation,
glycosylation, lipidation, acetylation, phosphorylation, or any other
manipulation, such as conjugation with a labeling component.
"fusion polypeptide" is a polypeptide comprising regions in a different
position in the sequence than occurs in nature. The regions can normally
exist in separate proteins and are brought together in the fusion
polypeptide; they can normally exist in the same protein but are placed in
a new arrangement in the fission polypeptide; or they can be synthetically
arranged. A "functionally equivalent fragment" of a polypeptide varies
from the native sequence by addition, deletion, or substitution of amino
acid residues, or any combination thereof, while preserving a functional
property of the fragment relevant to the context in which it is being
used. Fusion peptides and functionally equivalent fragments are included
in the definition of polypeptides used in this disclosure.
It is understood that the folding and the biological function of proteins
can accommodate insertions, deletions, and substitutions in the amino acid
sequence. Some amino acid substitutions are more easily tolerated. For
example, substitution of an amino acid with hydrophobic side chains,
aromatic side chains, polar side chains, side chains with a positive or
negative charge, or side chains comprising two or fewer carbon atoms, by
another amino acid with a side chain of like properties can occur without
disturbing the essential identity of the two sequences. Methods for
determining homologous regions and scoring the degree of homology are
described in Altschul et al. Bull. Math. Bio. 48:603-616, 1986; and
Henikoffet al. Proc. Natl. Acad. Sci. USA 89:10915-10919, 1992.
Substitutions that preserve the functionality of the polypeptide, or
confer a new and beneficial property (such as enhanced activity,
stability, or decreased immunogenicity) are especially preferred.
An "antibody" (interchangeably used in plural form) is an immunoglobulin
molecule capable of specific binding to a target, such as a polypeptide,
through at least one antigen recognition site, located in the variable
region of the immunoglobulin molecule. As used herein, the term
encompasses not only intact antibodies, but also antibody equivalents that
include at least one antigen combining site of the desired specificity.
These include but are not limited to enzymatic or recombinantly produced
fragments antibody, fusion proteins, humanized antibodies, single chain
variable regions, diabodies, and antibody chains that undergo
antigen-induced assembly. In one embodiment the antibody is a monoclonal
antibody. In another embodiment the antibody is a polyclonal antibody. The
antibody may be chimeric, human or murine or a hybrid thereof which are
known to those skilled in the art. Specifically binds to an "antibody" or
"specifically immunoreactive with", when referring to the recombinant
antibody or proteins refers to the binding of a cell or protein to the TNF
so as to modulate, decrease, suppress, inavtivate the activity of TNF.
Polyclonal antibodies against these peptides may be produced by immunizing
animals using the selected peptides. Monoclonal antibodies are prepared
using hybridoma technology by fusing antibody producing B cells from
immunized animals with myeloma cells and selecting the resulting hybridoma
cell line producing the desired antibody. Alternatively, monoclonal
antibodies may be produced by in vitro techniques known to a person of
ordinary skill in the art These antibodies are useful to detect the
expression of polypeptide encoded by the isolated DNA molecule of the DNA
virus in living animals, in humans, or in biological tissues or fluids
isolated from animals or humans.
Antibodies Polyclonal antibodies can be prepared by injecting a vertebrate
with a polypeptide of this invention in an immunogenic form.
Immunogenicity of a polypeptide can be enhanced by linking to a carrier
such as KLH, or combining with an adjuvant, such as Freund's adjuvant.
Typically, a priming injection is followed by a booster injection is after
about 4 weeks, and antiserum is harvested a week later. Unwanted activity
cross-reacting with other antigens, if present, can be removed, for
example, by running the preparation over adsorbants made of those antigens
attached to a solid phase, and collecting the unbound fraction. If
desired, the specific antibody activity can be further purified by a
combination of techniques, which may include protein, A chromatography,
ammonium sulfate precipitation, ion exchange chromatography, HPLC, and
immunoaffinity chromatography using the immunizing polypeptide coupled to
a solid support. Antibody fragments and other derivatives can be prepared
by standard immunochemical methods, such as subjecting the antibody to
cleavage with enzymes such as papain or pepsin.
The antibody may be labeled with a detectable marker including, but not
limited to: a radioactive label, or a colorimetric, a luminescent, or a
fluorescent marker, or gold. Radioactive labels include, but are not
limited to: 3 H, 14 C, 32 P, 33 P; 35 S, 36
Cl, 51 Cr, 57 Co, 59 Co, 59 Fe, 90 Y, 125 I,
131 I, and 186 Re. Fluorescent markers include but are not
limited to: fluorescein, rhodamine and auramine. Colorimetric markers
include, but are not limited to: biotin, and digoxigenin. Examples of
types of labels encompassed by the present invention include, but are not
limited to, radioisotopic labels (e.g., 3 H, 125 I, 131 I,
35 S, 14 C, etc.), non-radioactive isotopic labels (e.g.,
55 Mn, 56 Fe, etc.), fluorescent labels (e.g., a fluorescein
label, an isothiocyanate label, a rhodamine label, a phycoerythrin label,
a phycocyanin label, an allophycocyanin label, art O-phthaldehyde label, a
fluorescamine label, etc.) for example, as in peridinin chlorophyll
protein (PerCP), chemiluminescent labels, enzyme labels (e.g., alkaline
phosphatase, horse radish peroxidase, etc.), protein labels, labels useful
in radioimaging and radioimmunoimaging.
Variant(s), as the term is used herein, are polynucleotides or
polypeptides that differ from a reference polynucleotide or polypeptide
respectively. Variants in this sense are described below and elsewhere in
the present disclosure in greater detail. (1) A polynucleotide that
differs in nucleotide sequence from another, reference polynucleotide.
Changes in the nucleotide sequence of the variant may be silent, i.e.,
they may not alter the amino acids encoded by the polynucleotide. Where
alterations are limited to silent changes of this type a variant will
encode a polypeptide with the sane amino acid sequence as the reference
polypeptide. Changes in the nucleotide sequence of the variant may alter
the amino acid sequence of a polypeptide encoded by the reference
polynucleotide. Such nucleotide changes may result in amino acid
substitutions, additions, deletions, fusions and truncations in the
polypeptide encoded by the reference sequence, as discussed below. (2) A
polypeptide that differs in amino acid sequence from another, reference
polypeptide. Generally, differences are limited so that the sequences of
the reference and the variant are closely similar overall and, in many
region, identical. A variant and reference polypeptide may differ in amino
acid sequence by one or more substitutions, additions, deletions, fusions
and truncations, which may be present in any combination. (3) A variant
may also be a fragment of a polynucleotide or polypeptide of the invention
that differs from a reference polynucleotide or polypeptide sequence by
being shorter than the reference sequence, such as by a terminal or
internal deletion. A variant of a polypeptide of the invention also
includes a polypeptide which retains essentially the same biological
function or activity as such polypeptide, e.g., proproteins which can be
activated by cleavage of the proprotein portion to produce an active
mature polypeptide. (4) A variant may also be (i) one in which one or more
of the amine acid residues are substituted with a conserved or
non-conserved amino acid residue preferably a conserved amino acid
residue) and such substituted amino acid residue may or may not be one
encoded by the genetic code, or (ii) one in which one or more of the amino
acid residues includes a substituent group, or (iii) one in which the
mature polypeptide is fused with another compound, such as a compound to
increase the half-life of the polypeptide (for example, polyethylene
glycol), or (iv) one in which the additional amino acids are fused to the
mature polypeptide, such as a leader or secretory sequence or a sequence
which is employed for purification of the mature polypeptide or a
proprotein sequence. (5) A variant of the polynucleotide or polypeptide
may be a naturally occurring variant such as a naturally occurring allelic
variant, or it may be a variant that is not known to occur naturally. Such
non-naturally occurring variants of the polynucleotide may be made by
mutagenesis techniques, including those applied to polynucleotides, cells
or organisms, or may be made by recombinant means. Among polynucleotide
variants in this regard are variants that differ from the aforementioned
polynucleotides by nucleotide substitutions, deletions or additions. The
substitutions, deletions or additions may involve one or more nucleotides.
The variants may be altered in coding or noncoding regions or both.
Alterations in the coding regions may produce conservative or
non-conservative amino acid substitutions, deletions or additions. All
such variants defined above are deemed to be within the scope of those
skilled in the art from the teachings herein and from the at.
Antisense nucleotides or polynucleotide sequences are useful in preventing
or diminishing the expression of TNF are known to those skilled in the
art. Also, this invention provides an antisense molecule capable of
specifically hybridizing with TNF.alpha. to inhibit or repress production
of TNF.alpha.. This invention provides an antagonist capable of blocking
the expression of TNF. In one embodiment the antagonist is capable of
hybridizing with a double stranded DNA molecule. In another embodiment the
antagonist is a triplex oligonucleotide capable of hybridizing to the DNA
molecule. In another embodiment the triplex oligonucleotide is capable of
binding to at least a portion of TNF.
The antisense molecule may be DNA or RNA or variants thereof (i.e. DNA or
RNA with a protein backbone). The present invention extends to the
preparation of antisense nucleotides and ribozymes that may be used to
interfere with the expression of the receptor recognition proteins at the
translation of a specific mRNA, either by masking that MRNA with an
antisense nucleic acid or cleaving it with a ribozyme.
Antisense nucleic acids are DNA or RNA molecules that are complementary to
at least a portion of a specific MRNA molecule. In the cell, they
hybridize to that MRNA forming a double stranded molecule. The cell does
not translate an MRNA in this double-stranded form. Therefore, antisense
nucleic acids interfere with the expression of MRNA into protein.
Oligonucleotides which are complementary to TNF and which may bind to TNF
and inhibit production of TNF may be obtained as follows: The polymerase
reaction is then carried out using the two primers. See PCR Protocols: A
Guide to Methods and Applications [74]. Following PCR amplification, the
PCR-amplified regions of a viral DNA can be tested for their ability to
hybridize to the three specific nucleic acid probes listed above.
Alternatively, hybridization of a viral DNA to the above nucleic acid
probes can be performed by a Southern blot procedure without viral DNA
amplification and under stringent hybridization conditions as described
herein.
High stringent hybridization conditions are selected at about 5 C. lower
than the thermal melting point (Tm) for the specific sequence at a defined
ionic strength and pH. The Tm is the temperature (under defined ionic
strength and pH) at which 50% of the target sequence hybridizes to a
perfectly matched probe. Typically, stringent conditions will be those in
which the salt concentration is at least about 0.02 molar at pH 7 and the
temperature is at least about 60 C. As other factors may significantly
affect the stringency of hybridization, including, among others, base
composition and size of the complementary stands, the presence of organic
solvents, ie. salt or formamide concentration, and the extent of base
mismatching, the combination of parameters is more important than the
absolute measure of any one. For Example high stringency may be attained
for example by overnight hybridization at about 68 C. in a 6xSSC
solution, washing at room temperature with 6xSSC solution, followed
by washing at about 68 C. in a 6xSSC in a 0.6xSSX solution
Hybridization with moderate stringency may be attained for example by: 1)
filter pre-hybridizing and hybridizing with a solution of 3xsodium
chloride, sodium citrate (SSC), 50% formamide, 0.1M Tris buffer at Ph 7.5,
5xDenhardt's solution; 2) pre-hybridization at 37 C. for 4 hours; 3)
hybridization at 37 C. with amount of labelled probe equal to 3,000,000
cpm total for 16 hours; 4) wash in 2xSSC and 0.1% SDS solution; 5)
wash 4x for 1 minute each at room temperature at 4x at 60 C.
for 30 minutes each; and 6) dry and expose to film.
The phrase "selectively hybridizing to" refers to a nucleic acid probe
that hybridizes, duplexes or binds only to a particular target DNA or RNA
sequence when the target sequences are present in a preparation of total
cellular DNA or RNA. By selectively hybridizing it is meant that a probe
binds to a given target in a manner that is detectable in a different
manner from non-target sequence under high stringency conditions of
hybridization. in a different "Complementary" or "target" nucleic acid
sequences refer to those nucleic acid sequences which selectively
hybridize to a nucleic acid probe. Proper annealing conditions depend, for
example, upon a probe's length, base composition, and the number of
mismatches and their position on the probe, and must often be determined
empirically. For discussions of nucleic acid probe design and annealing
conditions, see, for example, Sambrook et al., [81] or Ausubel, F., et
al., [8].
As used herein, "pharmaceutical composition" means therapeutically
effective amounts of the compound or composition containing the molecule
of the invention as described above together with suitable diluents,
preservatives, solubilizers, emulsifiers, adjuvant and/or carriers. A
"therapeutically effective amount" as used herein refers to that amount
which provides a therapeutic effect for a given condition and
administration regimen. Such compositions are liquids or lyophilized or
otherwise dried formulations and include diluents of various buffer
content (e.g., Tris-HCl., acetate, phosphate), pH and ionic strength,
additives such as albumin or gelatin to prevent absorption to surfaces,
detergents (e.g., Tween 20, Tween 80, Pluronic F68, bile acid salts).
solubilizing agents (e.g., glycerol, polyethylene glycerol), anti-oxidants
(e.g., ascorbic acid, sodium metabisulfite), preservatives (e.g.,
Thimerosal, benzyl alcohol, parabens), bulking substances or tonicity
modifiers (e.g., lactose, mannitol), covalent attachment of polymers such
as polyethylene glycol to the protein, complexation with metal ions, or
incorporation of the material into or onto particulate preparations of
polymeric compounds such as polylactic acid, polglycolic acid, hydrogels,
etc, or onto liposomes, microemulsions, micelles, unilamelar or
multilamellar vesicles, erythrocyte ghosts, or spheroplasts. Other
embodiments of the compositions of the invention incorporate particulate
forms protective coatings, protease inhibitors or permeation enhancers for
various routes of administration, including parenteral, pulmonary, nasal
and oral. In one embodiment the pharmaceutical composition is administered
parenterally, intratumorally, paracancerally, transmucosally,
transdermally, intramuscularly, intravenously, intradermally,
intravascularly, subcutaneously, intraperitonealy, intraventricularly,
intracranially, topical drops or ointment, periocular injection,
systemically by intravenous injection or orally, intracamerally into the
anterior chamber or vitreous, via a depot attached to the intraocular lens
implant inserted during surgery, or via a depot placed in the eye sutured
in the anterior chamber or vitreous.
Further, as used herein "pharmaceutically acceptable carrier" are well
known to those skilled in the art and include, but are not limited to,
0.01-0.1M and preferably 0.05M phosphate buffer or 0.8% saline.
Additionally, such pharmaceutically acceptable carriers may be 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. Parenteral vehicles
include sodium chloride solution, Ringer's dextrose, dextrose and sodium
chloride, lactated Ringer's or Axed oils. Intravenous vehicles include
fluid and nutrient replenishers, electrolyte replenishers such as those
based on Ringer's dextrose, and the like. Preservatives and other
additives may also be present, such as, for example, antimicrobial,
antioxidants, collating agents, inert gases and the like.
The term "adjuvant" refers to a compound or mixture that enhances the
immune response to an antigen. An adjuvant can serve as a tissue depot
that slowly releases the antigen and also as a lymphoid system activator
that non-specifically enhances the immune response (Hood et al.,
Immunology, Second Ed., 1984, Benjamin/Cummings: Menlo Park, Calif., p.
384). Often, a primary challenge with an antigen alone, in the absence of
an adjuvant, will fail to elicit a humoral or cellular immune response.
Adjuvant include, but are not limited to, complete Freud's adjuvant,
incomplete Freud's adjuvant, saponin, mineral gels such as aluminum
hydroxide, surface active substances such as lysolecithin, pluronic
polyols, polyanions, peptides, oil or hydrocarbon emulsions, keyhole
limpet hemocyanins, dinitrophenol. Preferably, the adjuvant is
pharmaceutically acceptable.
Controlled or sustained release compositions include formulation in
lipophilic depots (e.g. fatty acids, waxes, oils). Also comprehended by
the invention are particulate compositions coated with polymers (e.g.
poloxamers or poloxamines) and the compound coupled to antibodies directed
against tissue-specific receptors, ligands or antigens or coupled to
ligands of tissue-specific receptors. Other embodiments of the
compositions of the invention incorporate particulate forms protective
coatings, protease inhibitors or permeation enhancers for various routes
of administration, including parenteral, pulmonary, nasal and oral.
Suitable excipients are, for example, water, saline, dextrose, glycerol,
ethanol, or the like and combinations thereof. In addition, if desired,
the composition can contain minor amounts of auxiliary substances such as
wetting or emulsifying agents, pH buffering agents which enhance the
effectiveness of the active ingredient.
An active component can be formulated into the therapeutic composition as
neutralized pharmaceutically acceptable salt forms. Pharmaceutically
acceptable salts include the acid addition salts and which are formed with
inorganic acids such as, for example, hydrochloric or phosphoric acids, or
such organic acids as acetic, oxalic, tartaric, mandelic, and the like.
Salts formed from the free carboxyl groups can also be derived from
inorganic bases such as, for example, sodium, potassium, ammonium,
calcium, or ferric hydroxides, and such organic bases as isopropylamine,
trimethylamine, 2-ethylamino ethanol, histidine, procaine, and the like.
The pharmaceutically acceptable form of the composition includes a
pharmaceutically acceptable carrier. In the therapeutic methods and
compositions of the invention, a therapeutically effective dosage of the
active component is provided. A worker based on patient characteristics
(age, weight, sex, condition, complications, other diseases, etc.), as is
well known in the art. Furthermore, as further routine studies are
conducted, more specific information will emerge regarding appropriate
dosage levels for treatment of various conditions in various patients, and
the ordinary skilled worker, considering the therapeutic context, age and
general health of the recipient, is able to ascertain proper dosing.
Generally, for intravenous injection or infusion, dosage may be lower than
for intraperitoneal, intramuscular, or other route of administration. The
dosing schedule may vary, depending on the circulation half-life, and the
formulation used. The compositions are administered in a manner compatible
with the dosage formulation in the therapeutically effective amount.
Precise amounts of active ingredient required to be administered depend on
the judgment of the practitioner and are peculiar to each individual.
However, suitable dosages may range from about 0.1 to 20, preferably about
0.5 to about 10, and more preferably one to several, milligrams of active
ingredient per kilogram body weight of individual per day and depend on
the route of administration. Suitable regimes for initial administration
and booster shots are also variable, but are typified by an initial
administration followed by repeated doses at one or more hour intervals by
a subsequent injection or other administration. Alternatively, continuous
intravenous, infusion sufficient to maintain concentrations of ten
nanomolar to ten micromolar in the blood are contemplated.
