BACKGROUND

[0003] Inflammatory disease, fibrostenotic disease, and fibrotic disease pose a significant health burden worldwide due to the vast number of individuals affected and heterogeneous disease pathogenesis and varied clinical manifestations. One such disease is inflammatory bowel disease (IBD), which has two common forms, Crohn’s disease (CD) and ulcerative colitis (UC). IBD is comprises of chronic, relapsing inflammatory disorders of the gastrointestinal tract. Incidences of IBD are prevalent, affecting nearly three million individuals in the United States alone. Each of these forms has various sub -conditions known as subclinical phenotypes that are present in sub-populations of CD and UC patients. One such condition is obstructive Crohn’s disease, which can result from long term inflammation that may lead to the formation of scar tissue in the intestinal wall (fibrostenosis) or swelling. Both outcomes can cause narrowing, or obstruction, and are known as either fibrotic or inflammatory strictures. Severe strictures can lead to blockage of the intestine, leading to abdominal pain, bloating, nausea and the inability to pass stool.

[0004] Few treatment options are available to patients that suffer from inflammatory disease, fibrostenotic disease, and fibrotic disease. Existing anti-inflammatory therapy such as steroids and tumor necrosis factor (TNF) inhibitors are typically use as a first line treatment for treating IBD. Unfortunately, a significant number of patients experience a lack of response or a loss of response to existing anti inflammatory therapies, especially TNF inhibitors. While the patient is treated with an anti-inflammatory therapy that is ineffective, the disease worsens. Surgery, in the form of structureplasty (reshaping of the intestine) or resection (removal of the intestine), is the only treatment option for patients that do not respond to first line therapies. Surgical treatments for IBD are invasive, causing post-operative risks for an estimated third of patients undergoing surgery, such as anastomotic leak, infection, and bleeding.

[0005] The pathogenesis of inflammatory disease, fibrostenotic disease, and fibrotic disease, like IBD is thought to involve an uncontrolled immune response that may be triggered by certain environmental factors in a genetically susceptible host. The heterogeneity of disease pathogenesis and clinical course, combined with the variable response to treatment and its associated side effects, suggests a personalized medicine approach to treating these diseases is best treatment strategy. Yet there are very few

personalized therapies available to patients. Accordingly, there is a need to identify targeted therapeutic approaches for the treatment of inflammatory disease, fibrostenotic disease, and fibrotic disease and subclinical phenotypes thereof, and an even greater need to develop reliable methodology to identifying patients who, based on their genotype, who may respond to any given therapeutic approach. The needed methodologies would also identify subjects not yet diagnosed who are at risk of developing the disease, for which preventative interventions could be prescribed to reduce the growing health burden.

SUMMARY

[0006] CD30 ligand (CD30L) is a ligand of CD30 encoded by the gene tumor necrosis factor receptor superfamily 8 or (TNFSF8). CD30L is a member of the tumor necrosis factor superfamily and is important in co-stimulation of immune cells to induce cellular proliferation and cytokine production. In some cases, CD30L acts on proinflammatory cytokines, such as interleukin 6 (IL-6). Preliminary studies suggest that the CD30L pathway is a dominant pathway in the pathogenesis of inflammatory, fibrotic and fibrostenotic disease such as IBD, especially in certain subsets of patients with complicated forms of the disease (e.g, such as stricturing, penetrating, or obstructive disease phenotypes).

[0007] Aspects of the present application provide methods and system for treating an inflammatory disease in a subject with an inhibitor of CD30L.In some cases, the CD30L inhibitor inhibits, attenuates, or otherwise interferes with a biological response related to CD30L interaction with its cognate antigen, CD30. Accordingly, in some cases treatment with a CD30L inhibitor is useful to treat conditions with which an expression or activity of CD30 ligand or CD30 are associated.

[0008] Also described herein, are polymorphisms and haplotypes thereof at the TNFSF8 gene or genetic locus that are associated with inflammatory, fibrotic or fibrostenotic disease. TNFSF8 polymorphisms may be associated with inflammatory bowel disease (IBD) and various subclinical phenotypes of IBD. In addition, these polymorphisms affect expression of CD30L, and in some cases, CD30. Genotypes comprising the TNFSF8 polymorphisms described herein can be detected in a sample obtained from a subject who may or may not be diagnosed with IBD. Detection of the genotypes, facilitated by existing genotyping assays, can be done at the point of need or in medical health care facility. Exemplary genotyping assays involve hybridization assays using nucleic acid probes specific for said polymorphisms.

[0009] Practical applications of the associations between the genotypes described herein and incidences of clinical and subclinical phenotypes in certain populations of individuals are provided herein. For example, the genotypes of the present disclosure can be used to predict a risk that a subject will develop an inflammatory disease, fibrostenotic disease, or a fibrotic disease. The genotypes are also useful to predict whether a patient diagnosed with some form of an inflammatory, fibrotic or fibrostenotic disease will develop a severe form of the disease, such as a subclinical phenotype thereof. In addition, or alternatively, the genotypes disclosed herein are associated with an variation in an expression of CD30 or CD30L, which in some cases, means the genotypes can be used to identify a patient who may be suitable for treatment with a targeted CD30L therapy (e.g., a patient carrying a genotype associated with an increase in CD30L may be suitable for a treatment with an anti-CD30L or anti-CD30 therapy). Exemplary conditions include both Crohn’s disease (CD) and primary sclerosing cholangitis. In some cases, a subject is administered a therapeutic agent (e.g., CD30L inhibitor, TL1A inhibitor) provided the genotype disclosed herein is detected in a sample obtained from the subject. A further example of practical applications disclosed herein include laboratory-based methods of detecting the instant genotypes, such as quantitative PCR (qPCR) and sequencing methodologies.

[0022] The present disclosure provides methods and systems for detecting the presence or absence of a particular genotype in a subject, which in some cases, is useful for selecting subjects for a particular treatment of a certain disease or condition, identifying a risk of developing a clinical or subclinical phenotype, or a combination thereof. In some embodiments, the genotype comprises a polymorphism at rs911605 (SEQ ID NO: 1) and optionally rsl006026 (SEQ ID NO: 3). As an example, the genotype is a haplotype comprising a polymorphism at both rs911605 and rs 1006026. In some cases, the presence of the particular genotype indicates that the subject has elevated expression of CD30 ligand (CD30L). In some cases, the presence of the particular genotype indicates that the subject has elevated levels of soluble CD30. In some cases, the presence of the particular genotype indicates that the subject has elevated expression of the tumor necrosis factor (TNF) family cytokine, TL1A ( TNFSF15 ). Accordingly, subjects positive for said genotype may be suitable for treatment with a CD30L inhibitor, such as an anti-CD30L antibody. Subject positive for said genotype may also be suitable for treatment with a TL1A inhibitor.

For example, the CD30L inhibitor and the TL1A inhibitor may be useful to treat a disease or condition associated with CD30L/CD30 or TL1A activity, such at least one of an inflammatory disease, fibrostenotic disease, and fibrotic disease. Non-limiting examples of inflammatory diseases include diseases of the gastrointestinal tract, liver, and gallbladder; including Crohn’s disease (CD). An exemplary fibrotic disease is primary sclerosing cholangitis (PSC).

[0023] In some embodiments, methods and systems are provided for identifying whether or not a subject has a polymorphism at rs911605 and/or rsl006026. In some cases, the polymorphism comprises an“A” allele at position 501 of rs911605 (SEQ ID NO: 2). In some cases, the polymorphism comprises a “G” allele at position 501 of rsl006026 (SEQ ID NO: 4). Exemplary methods include a hybridization assay that comprises contacting genetic material from the subject with a probe comprising a nucleic acid sequence hybridizable to at least a portion (e.g., at least about 10 nucleobases) of a nucleic acid sequence comprising a polymorphism. As an example, a method comprises contacting the genetic material with a probe comprising at least about 10 contiguous nucleobases of rs911605 (SEQ ID NO: 1 or SEQ ID NO: 2), wherein the probe comprises at least the nucleobase at position 501. As another example, a method comprises contacting the genetic material with a probe comprising at least about 10 contiguous nucleobases of rsl006026 (SEQ ID NO: 3 or SEQ ID NO: 4), wherein the probe comprises at least the nucleobase at position 501. Additional probes include those having a sequence that is a reverse complement to those described herein, e.g., a reverse complement to any of SEQ ID NOS: 1-4. In some cases, a method comprises a multiplex assay comprising contacting the genetic material with two or more probes, e.g., one or more probes specific for a polymorphism at rs911605 and one or more probes specific for a polymorphism at rs 1006026. Suitable hybridization assays include quantitative polymerase chain reaction (qPCR). For example, the qPCR is a TaqMan™ assay.

[0024] Further provided are compositions and kits for detecting the presence of a particular genotype or haplotype, e.g., a polymorphism at rs911605 and/or rsl006026. In some cases, the kits comprise regents such as primers and/or probes configured to amplify and/or detect the genotype from a genetic sample of a subject. In some cases, the kits comprise a sample collection device. Some such devices are useful for obtaining a sample comprising genetic material from a subject. An exemplary collection device is a swab. For use in collecting samples, one method involves contacting the swab to the surface of the subject to be tested, for example, the inner check. Another exemplary collection device is a tube for collection of a blood sample from the subject. In some cases the tube comprises an additive for preservation and/or to facilitate analysis. For example, the tube comprises heparin, potassium oxalate, sodium fluoride, ethylenediaminetetraacetic acid (EDTA), sodium citrate, reagents that activate or reduce clotting, reagents that separate serum, or a combination thereof.

[0025] Further provided are CD30L inhibitors and other therapeutic agents, which may be administered to a patient having an inflammatory disease, fibrostenotic disease, and/or fibrotic disease. In some cases the other therapeutic agent may comprise a TL1A inhibitor. A non-limiting example of a CD30L inhibitor is an anti-CD30L antibody, such as the antibodies disclosed elsewhere herein. A non limiting example of a TL1A inhibitor is an anti-TLlA antibody, such as the antibodies discloses herein. In some embodiments, the patient comprises a genotype disclosed herein, e.g., a polymorphism at rs911605 and/or rs 1006026.

[0041] CD30, and nucleic acids encoding CD30 (TNFSF8), are characterized by NCBI Entrez Gene

ID 944. CD30 is a transmembrane receptor for its ligand, CD30L, each belonging to the tumor necrosis factor (TNF) family. In some embodiments, a presence of a genotype comprising one or more polymorphisms in Table 13, is associated with a decreased level of CD30, as compared to a level of CD30 in an individual who does not have the genotype. In some embodiments, a presence of a genotype comprising one or more polymorphisms in Table 14 is associated with an increase in the level of CD30, as compared to a level of CD30 in an individual who does not have the genotype. In some instances, detection of the genotype associated with the decrease in CD30 in a sample obtained from a subject is indicative that the subject has a decreased level of CD30, as compared to an individual who does not have the genotype. In some instances, detection of the genotype associated with the increase in CD30 in a sample obtained from a subject is indicative that the subject has an increased level of CD30, as compared to an individual who does not have the genotype. An increase or a decrease in CD30 may suggest a corresponding increase or decrease in its ligand, CD30L.

[0043] In some instances, the increase or decrease in CD30 or CD30L is expressed as fold-change. “Fold-change,” as used herein, refers to a change in a quantity or level of expression of a gene, or gene expression product thereof, from an initial to a final value. Fold-change may be measured over a period of time, or at a single point in time, or a combination thereof. Fold-change may be an increase or a decrease as compared to the initial value. In some embodiments, the gene comprises deoxynucleic ribonucleic acid (DNA). In some embodiments, the gene expression product comprises ribonucleic acid (RNA), or protein, or both. In some embodiments, the RNA comprises messenger RNA (mRNA). In some embodiments, the increase or decrease in CD30 or CD30L fold-change comprises an increase of 1.1-fold, 1.2-fold, 1.3-fold, 1.4-fold, 1.5 fold, 1.6-fold, 1.7-fold, 1.8-fold, 1.9-fold, 2.0-fold, 2.1-fold, 2.2-fold, 2.3-fold, 2.4-fold, 2.5- fold, 2.6-fold, 2.7-fold, 2.8-fold, 2.0-fold, 3.0-fold, 3.1-fold, 3.2-fold, 3.3-fold, 3.4-fold, 3.5-fold, 4-fold, 5-fold, 10-fold, 20-fold, 30-fold, 40-fold, 50-fold, 60-fold, 70-fold, 80-fold, 90-fold, or 100-fold or more between the sample obtained from a subject and an expression of CD30 or CD30L in an individual who does not have the genotype associated with the increase or decrease fold-change. [0044] In some embodiments, the increase or the decrease in CD30 or CD30L in a subject is indicative that the subject has, or will develop, a particular disease or condition. In some instances, a subject having the particular disease or condition that is related to the presence of a genotype associated with increased levels of CD30 or CD30L in the subject is suitable for treatment with an inhibitor of CD30L, such as an anti-CD30L antibody. In some instances, a subject having the particular disease or condition that is related to the presence of a genotype associated with decreased levels of CD30 or CD30L in the subject is suitable for treatment with an agonist of CD30L or CD30.

Exemplary methods include use of surface plasmon resonance to evaluate whether an anti-TLIA antibody can compete with the binding between TL1A and another anti-TLIA antibody. In some cases, surface plasmon resonance is utilized in the competition assay.

Pharmaceutical compositions, formulations, and methods of administration

[00137] In one aspect, a method for treating any of the diseases or conditions described herein in a subject in need of such treatment, involves administration of pharmaceutical compositions that include a therapeutic agent described herein, e.g., an inhibitor of CD30L, in therapeutically effective amounts to said subject. In some embodiments, a therapeutic agent described herein is used in the preparation of medicaments for treating an inflammatory disease, fibrostenotic disease, and/or fibrotic disease.

Pharmaceutical compositions as used herein include compositions comprising an inhibitor of CD30L and optionally an additional therapeutic agent.

[00138] In certain embodiments, the compositions containing the therapeutic agent described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest at least one of the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation clinical trial. In some cases, an inhibitor of CD30L is administered to a patient suffering from an inflammatory disease, fibrostenotic disease, and/or fibrotic disease.

[00139] In prophylactic applications, compositions containing a therapeutic agent described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition, e.g., an inflammatory disease, fibrostenotic disease, and/or fibrotic disease. Such an amount is defined to be a "prophylactically effective amount or dose." In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in a patient, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. In one aspect, prophylactic treatments include administering to a mammal, who previously experienced at least one symptom of the disease being treated and is currently in remission, a pharmaceutical composition comprising an inhibitor of CD30L in order to prevent a return of the symptoms of the disease or condition.

[00140] In certain embodiments wherein the patient’s condition does not improve, upon the doctor’s discretion the administration of therapeutic agent is administered chronically, that is, for an extended period of time, including throughout the duration of the patient’s life in order to ameliorate or otherwise control or limit the symptoms of the patient’s disease or condition.

[00141] In certain embodiments wherein a patient’s status does improve, the dose of therapeutic agent being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a“drug holiday”). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug holiday is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%.

[00142] In certain embodiments, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a“drug diversion”). In specific embodiments, the length of the drug diversion is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug diversion is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%. After a suitable length of time, the normal dosing schedule is optionally reinstated.

[00143] In some embodiments, once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent treatment on a long-term basis upon any recurrence of symptoms.

[00144] The amount of a given therapeutic agent that corresponds to such an amount varies depending upon factors such as the particular therapeutic agent, disease condition and its severity, the identity (e.g., weight, sex) of the subject in need of treatment, but can nevertheless be determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment are typically in the range of 0.01 mg-5000 mg per day. In one aspect, doses employed for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.

[00145] In some embodiments, as a patient is started on a regimen of a therapeutic agent, the patient is also weaned off (e.g., step-wise decrease in dose) a second treatment regimen.

[00146] In one embodiment, the daily dosages appropriate for an inhibitor of CD30L herein are from about 0.01 to about 10 mg/kg per body weight. In specific embodiments, an indicated daily dosage in a large mammal, including, but not limited to, humans, is in the range from about 0.5 mg to about 1000 mg, conveniently administered in divided doses, including, but not limited to, up to four times a day. In some embodiments, the daily dosage is administered in extended release form. In certain embodiments, suitable unit dosage forms for oral administration comprise from about 1 to 500 mg active ingredient. In some embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the therapeutic agent used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.

[00147] Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD ₅₀ and the ED ₅₀ . The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD ₅₀ and ED ₅₀ . In certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans. In some embodiments, the daily dosage amount of the therapeutic agent described herein lies within a range of circulating concentrations that include the ED ₅₀ with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized.

[00148] Disclosed herein are therapeutic agents formulated into pharmaceutical compositions. The pharmaceutical composition may comprise an inhibitor of anti-CD30L The pharmaceutical composition may comprise an antibody. The pharmaceutical composition may comprise an anti-CD30L antibody.

[00149] Pharmaceutical compositions are formulated in a conventional manner using one or more pharmaceutically acceptable inactive ingredients that facilitate processing of the active therapeutic agent into preparations that can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. A summary of pharmaceutical compositions described herein can be found, for example, in Remington: The Science and Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: Mack Publishing Company, 1995); Hoover, John E., Remington’s Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania 1975; Liberman, H.A. and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York, N.Y., 1980; and Pharmaceutical Dosage Forms and Drug Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkins, 1999), herein incorporated by reference for such disclosure. [00150] Provided herein are pharmaceutical compositions that include an inhibitor of CD30L, and at least one pharmaceutically acceptable inactive ingredient. Optionally, the compositions include other therapeutic agent as discussed herein. In some embodiments, the therapeutic agents described herein are administered as pharmaceutical compositions in which the therapeutic agents are mixed with other active ingredients, as in combination therapy. In some embodiments, the pharmaceutical compositions include other medicinal or pharmaceutical agents, carriers, adjuvants, preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure, and/or buffers. In some embodiments, the pharmaceutical compositions include other therapeutically valuable substances.

[00151] A pharmaceutical composition, as used herein, refers to a mixture of a therapeutic agent, e.g., an inhibitor of CD30L, with other chemical components (i.e. pharmaceutically acceptable inactive ingredients), such as carriers, excipients, binders, fdling agents, suspending agents, flavoring agents, sweetening agents, disintegrating agents, dispersing agents, surfactants, lubricants, colorants, diluents, solubilizers, moistening agents, plasticizers, stabilizers, penetration enhancers, wetting agents, anti- foammg agents, antioxidants, preservatives, or one or more combination thereof. Optionally, the compositions include two or more therapeutic agent as discussed herein. In practicing the methods of treatment or use provided herein, therapeutically effective amounts of therapeutic agents described herein are administered in a pharmaceutical composition to a mammal having a disease, disorder, or condition to be treated, e.g., an inflammatory disease, fibrostenotic disease, and/or fibrotic disease. In some embodiments, the mammal is a human. A therapeutically effective amount can vary widely depending on the severity of the disease, the age and relative health of the subject, the potency of the therapeutic agent used and other factors. The therapeutic agents can be used singly or in combination with one or more therapeutic agents as components of mixtures.

[00152] The pharmaceutical formulations described herein are administered to a subject by appropriate administration routes, including but not limited to, oral, parenteral (e.g., intravenous, subcutaneous, intramuscular), intranasal, buccal, topical, or transdermal administration routes. The pharmaceutical formulations described herein include, but are not limited to, aqueous liquid dispersions, self-emulsifying dispersions, solid solutions, liposomal dispersions, aerosols, solid dosage forms, powders, immediate release formulations, controlled release formulations, fast melt formulations, tablets, capsules, pills, delayed release formulations, extended release formulations, pulsatile release formulations,

multiparticulate formulations, and mixed immediate and controlled release formulations.

[00153] Pharmaceutical compositions including a therapeutic agent, e.g., inhibitor of anti-CD30L, are manufactured in a conventional manner, such as, by way of example only, by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or compression processes. Optionally, the compositions include another therapeutic agent, e.g., one as discussed herein.

[00154] The pharmaceutical compositions may include at least a therapeutic agent, e.g., inhibitor of anti- CD30L, as an active ingredient in free-acid or free-base form, or in a pharmaceutically acceptable salt form. In addition, the methods and pharmaceutical compositions described herein include the use of N- oxides (if appropriate), crystalline forms, amorphous phases, as well as active metabolites of these compounds having the same type of activity. In some embodiments, therapeutic agents exist in unsolvated form or in solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. The solvated forms of the therapeutic agents are also considered to be disclosed herein.

[00155] In some embodiments, a therapeutic agent exists as a tautomer. All tautomers are included within the scope of the agents presented herein. As such, it is to be understood that a therapeutic agent or a salt thereof may exhibit the phenomenon of tautomerism whereby two chemical compounds that are capable of facile interconversion by exchanging a hydrogen atom between two atoms, to either of which it forms a covalent bond. Since the tautomeric compounds exist in mobile equilibrium with each other they may be regarded as different isomeric forms of the same compound.

[00156] In some embodiments, a therapeutic agent exists as an enantiomer, diastereomer, or other steroisomenc form. The agents disclosed herein include all enantiomeric, diastereomeric, and epimeric forms as well as mixtures thereof.

[00157] In some embodiments, therapeutic agents described herein may be prepared as prodrugs. A "prodrug" refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. An example, without limitation, of a prodrug would be a therapeutic agent described herein, which is administered as an ester (the "prodrug") to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the therapeutic agent. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically,

pharmaceutically or therapeutically active form of the therapeutic agent.

[00158] Prodrug forms of the therapeutic agents, wherein the prodrug is metabolized in vivo to produce an agent as set forth herein are included within the scope of the claims. Prodmg forms of the herein described therapeutic agents, wherein the prodrug is metabolized in vivo to produce an agent as set forth herein are included within the scope of the claims. In some cases, some of the therapeutic agents described herein may be a prodrug for another derivative or active compound. In some embodiments described herein, hydrazones are metabolized in vivo to produce a therapeutic agent.

[00159] In certain embodiments, compositions provided herein include one or more preservatives to inhibit microbial activity. Suitable preservatives include mercury-containing substances such as merfen and thiomersal; stabilized chlorine dioxide; and quaternary ammonium compounds such as benzalkonium chloride, cetyltrimethylammonium bromide and cetylpyridinium chloride. [00160] In some embodiments, formulations described herein benefit from antioxidants, metal chelating agents, thiol containing compounds and other general stabilizing agents. Examples of such stabilizing agents, include, but are not limited to: (a) about 0.5% to about 2% w/v glycerol, (b) about 0.1% to about 1% w/v methionine, (c) about 0.1% to about 2% w/v monothioglycerol, (d) about 1 mM to about 10 mM EDTA, (e) about 0.01% to about 2% w/v ascorbic acid, (f) 0.003% to about 0.02% w/v polysorbate 80, (g) 0.001% to about 0.05% w/v. polysorbate 20, (h) arginine, (i) heparin, (j) dextran sulfate, (k) cyclodextrins, (1) pentosan polysulfate and other heparinoids, (m) divalent cations such as magnesium and zinc; or (n) combinations thereof.

[00161] The pharmaceutical compositions described herein, which include a therapeutic agent such an inhibitor of CD30L are formulated into any suitable dosage form, including but not limited to, aqueous oral dispersions, liquids, gels, syrups, elixirs, slurries, suspensions, solid oral dosage forms, aerosols, controlled release formulations, fast melt formulations, effervescent formulations, lyophilized formulations, tablets, powders, pills, dragees, capsules, delayed release formulations, extended release formulations, pulsatile release formulations, multiparticulate formulations, and mixed immediate release and controlled release formulations. In one aspect, a therapeutic agent as discussed herein, e.g., an inhibitor of CD30L is formulated into a pharmaceutical composition suitable for intramuscular, subcutaneous, or intravenous injection. In one aspect, formulations suitable for intramuscular, subcutaneous, or intravenous injection include physiologically acceptable sterile aqueous or non -aqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (propyleneglycol, polyethylene -glycol, glycerol, cremophor and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. In some embodiments, formulations suitable for subcutaneous injection also contain additives such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the growth of

microorganisms can be ensured by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, and the like. In some cases it is desirable to include isotonic agents, such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, such as aluminum monostearate and gelatin.

[00162] For intravenous injections or drips or infusions, a therapeutic agent described herein is formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank’s solution, Ringer’s solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. For other parenteral injections, appropriate formulations include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients. Such excipients are known. [00163] Parenteral injections may involve bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi -dose containers, with an added preservative. The pharmaceutical composition described herein may be in a form suitable for parenteral injection as a sterile suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. In one aspect, the active ingredient is in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

[00164] For administration by inhalation, a therapeutic agent is formulated for use as an aerosol, a mist or a powder. Pharmaceutical compositions described herein are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, such as, by way of example only, gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the therapeutic agent described herein and a suitable powder base such as lactose or starch.

[00165] Representative intranasal formulations are described in, for example, U.S. Pat. Nos. 4,476, 116, 5,116,817 and 6,391,452. Formulations that include a therapeutic agent are prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, fluorocarbons, and/or other solubilizing or dispersing agents known in the art. See, for example, Ansel, H. C. et al., Pharmaceutical Dosage Forms and Drug Delivery Systems, Sixth Ed. (1995). Preferably these compositions and formulations are prepared with suitable nontoxic pharmaceutically acceptable ingredients. These ingredients are known to those skilled in the preparation of nasal dosage forms and some of these can be found in REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY, 21st edition, 2005. The choice of suitable carriers is dependent upon the exact nature of the nasal dosage form desired, e.g., solutions, suspensions, ointments, or gels. Nasal dosage forms generally contain large amounts of water in addition to the active ingredient. Minor amounts of other ingredients such as pH adjusters, emulsifiers or dispersing agents, preservatives, surfactants, gelling agents, or buffering and other stabilizing and solubilizing agents are optionally present. Preferably, the nasal dosage form should be isotonic with nasal secretions.

[00166] Pharmaceutical preparations for oral use are obtained by mixing one or more solid excipient with one or more of the therapeutic agents described herein, optionally grinding the resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients include, for example, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methylcellulose, microcrystalline cellulose,

hydroxypropylmethylcellulose, sodium carboxymethylcellulose; or others such as: polyvinylpyrrolidone (PVP or povidone) or calcium phosphate. If desired, disintegrating agents are added, such as the cross-linked croscarmellose sodium, polyvinylpyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate. In some embodiments, dyestuffs or pigments are added to the tablets or dragee coatings for identification or to characterize different combinations of active therapeutic agent doses.

[00167] In some embodiments, pharmaceutical formulations of a therapeutic agent are in the form of a capsules, including push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active therapeutic agent is dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In some embodiments, stabilizers are added. A capsule may be prepared, for example, by placing the bulk blend of the formulation of the therapeutic agent inside of a capsule. In some embodiments, the formulations (non-aqueous suspensions and solutions) are placed in a soft gelatin capsule. In other embodiments, the formulations are placed in standard gelatin capsules or non-gelatin capsules such as capsules comprising HPMC. In other embodiments, the formulation is placed in a sprinkle capsule, wherein the capsule is swallowed whole or the capsule is opened and the contents sprinkled on food prior to eating.

[00168] All formulations for oral administration are in dosages suitable for such administration.

In some embodiments, the solid dosage forms disclosed herein are in the form of a tablet, (including a suspension tablet, a fast-melt tablet, a bite-disintegration tablet, a rapid-disintegration tablet, an effervescent tablet, or a caplet), a pill, a powder, a capsule, solid dispersion, solid solution, bioerodible dosage form, controlled release formulations, pulsatile release dosage forms, multiparticulate dosage forms, beads, pellets, granules. In other embodiments, the pharmaceutical formulation is in the form of a powder. Compressed tablets are solid dosage forms prepared by compacting the bulk blend of the formulations described above. In various embodiments, tablets will include one or more flavoring agents. In other embodiments, the tablets will include a film surrounding the final compressed tablet. In some embodiments, the film coating can provide a delayed release of a therapeutic agent from the formulation. In other embodiments, the film coating aids in patient compliance (e g., Opadry ^® coatings or sugar coating). Film coatings including Opadry ^® typically range from about 1% to about 3% of the tablet weight. In some embodiments, solid dosage forms, e.g., tablets, effervescent tablets, and capsules, are prepared by mixing particles of a therapeutic agent with one or more pharmaceutical excipients to form a bulk blend composition. The bulk blend is readily subdivided into equally effective unit dosage forms, such as tablets, pills, and capsules. In some embodiments, the individual unit dosages include film coatings. These formulations are manufactured by conventional formulation techniques.

[00169] In another aspect, dosage forms include microencapsulated formulations. In some

embodiments, one or more other compatible materials are present in the microencapsulation material. Exemplary materials include, but are not limited to, pH modifiers, erosion facilitators, anti-foaming agents, antioxidants, flavoring agents, and carrier materials such as binders, suspending agents, disintegration agents, filling agents, surfactants, solubilizers, stabilizers, lubricants, wetting agents, and diluents.

[00170] Liquid formulation dosage forms for oral administration are optionally aqueous suspensions selected from the group including, but not limited to, pharmaceutically acceptable aqueous oral dispersions, emulsions, solutions, elixirs, gels, and syrups. See, e.g., Singh et ah, Encyclopedia of Pharmaceutical Technology, 2nd Ed., pp. 754-757 (2002). In addition to therapeutic agent the liquid dosage forms optionally include additives, such as: (a) disintegrating agents; (b) dispersing agents; (c) wetting agents; (d) at least one preservative, (e) viscosity enhancing agents, (f) at least one sweetening agent, and (g) at least one flavoring agent. In some embodiments, the aqueous dispersions further includes a crystal -forming inhibitor.

[00171] In some embodiments, the pharmaceutical formulations described herein are self-emulsifying drug delivery systems (SEDDS). Emulsions are dispersions of one immiscible phase in another, usually in the form of droplets. Generally, emulsions are created by vigorous mechanical dispersion. SEDDS, as opposed to emulsions or microemulsions, spontaneously form emulsions when added to an excess of water without any external mechanical dispersion or agitation. An advantage of SEDDS is that only gentle mixing is required to distribute the droplets throughout the solution. Additionally, water or the aqueous phase is optionally added just prior to administration, which ensures stability of an unstable or hydrophobic active ingredient. Thus, the SEDDS provides an effective delivery system for oral and parenteral delivery of hydrophobic active ingredients. In some embodiments, SEDDS provides improvements in the bioavailability of hydrophobic active ingredients. Methods of producing self- emulsifying dosage forms include, but are not limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and 6,960,563.

[00172] Buccal formulations that include a therapeutic agent are administered using a variety of formulations known in the art. For example, such formulations include, but are not limited to, U.S. Pat. Nos. 4,229,447, 4,596,795, 4,755,386, and 5,739,136. In addition, the buccal dosage forms described herein can further include a bioerodible (hydrolysable) polymeric carrier that also serves to adhere the dosage form to the buccal mucosa. For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, or gels formulated in a conventional manner.

[00173] For intravenous injections, a therapeutic agent is optionally formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank’s solution, Ringer’s solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. For other parenteral injections, appropriate formulations include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients.

[00174] Parenteral injections optionally involve bolus injection or continuous infusion. Formulations for injection are optionally presented in unit dosage form, e.g., in ampoules or in multi dose containers, with an added preservative. In some embodiments, a pharmaceutical composition described herein is in a form suitable for parenteral injection as a stenle suspensions, solutions or emulsions in oily or aqueous vehicles, and contain formulatory agents such as suspending, stabilizing and/or dispersing agents.

[00187] It should be appreciated that there is considerable overlap between additives used in the solid dosage forms described herein. Thus, the above-listed additives should be taken as merely exemplary, and not limiting, of the types of additives that can be included in solid dosage forms of the pharmaceutical compositions described herein. The amounts of such additives can be readily determined by one skilled in the art, according to the particular properties desired.

[00188] In various embodiments, the particles of a therapeutic agents and one or more excipients are dry blended and compressed into a mass, such as a tablet, having a hardness sufficient to provide a pharmaceutical composition that substantially disintegrates within less than about 30 minutes, less than about 35 minutes, less than about 40 minutes, less than about 45 minutes, less than about 50 minutes, less than about 55 minutes, or less than about 60 minutes, after oral administration, thereby releasing the formulation into the gastrointestinal fluid.

[00189] In other embodiments, a powder including a therapeutic agent is formulated to include one or more pharmaceutical excipients and flavors. Such a powder is prepared, for example, by mixing the therapeutic agent and optional pharmaceutical excipients to form a bulk blend composition. Additional embodiments also include a suspending agent and/or a wetting agent. This bulk blend is uniformly subdivided into unit dosage packaging or multi -dosage packaging units.

[00190] In still other embodiments, effervescent powders are also prepared. Effervescent salts have been used to disperse medicines in water for oral administration.

[00191] In some embodiments, the pharmaceutical dosage forms are formulated to provide a controlled release of a therapeutic agent. Controlled release refers to the release of the therapeutic agent from a dosage form in which it is incorporated according to a desired profile over an extended period of time. Controlled release profiles include, for example, sustained release, prolonged release, pulsatile release, and delayed release profiles. In contrast to immediate release compositions, controlled release compositions allow delivery of an agent to a subject over an extended period of time according to a predetermined profile. Such release rates can provide therapeutically effective levels of agent for an extended period of time and thereby provide a longer period of pharmacologic response while minimizing side effects as compared to conventional rapid release dosage forms. Such longer periods of response provide for many inherent benefits that are not achieved with the corresponding short acting, immediate release preparations.

[00192] In some embodiments, the solid dosage forms described herein are formulated as enteric coated delayed release oral dosage forms, i.e., as an oral dosage form of a pharmaceutical composition as described herein which utilizes an enteric coating to affect release in the small intestine or large intestine. In one aspect, the enteric coated dosage form is a compressed or molded or extruded tablet/mold (coated or uncoated) containing granules, powder, pellets, beads or particles of the active ingredient and/or other composition components, which are themselves coated or uncoated. In one aspect, the entenc coated oral dosage form is in the form of a capsule containing pellets, beads or granules, which include a therapeutic agent that are coated or uncoated.

[00193] Any coatings should be applied to a sufficient thickness such that the entire coating does not dissolve in the gastrointestinal fluids at pH below about 5, but does dissolve at pH about 5 and above. Coatings are typically selected from any of the following: Shellac - this coating dissolves in media of pH >7; Acrylic polymers - examples of suitable acrylic polymers include methacrylic acid copolymers and ammonium methacrylate copolymers. The Eudragit series E, L, S, RL, RS and NE (Rohm Pharma) are available as solubilized in organic solvent, aqueous dispersion, or dry powders. The Eudragit series RL, NE, and RS are insoluble in the gastrointestinal tract but are permeable and are used primarily for colonic targeting. The Eudragit series E dissolve in the stomach. The Eudragit series L, L-30D and S are insoluble in stomach and dissolve in the intestine; Poly Vinyl Acetate Phthalate (PVAP) - PVAP dissolves in pH >5, and it is much less permeable to water vapor and gastric fluids. Conventional coating techniques such as spray or pan coating are employed to apply coatings. The coating thickness must be sufficient to ensure that the oral dosage form remains intact until the desired site of topical delivery in the intestinal tract is reached.

[00194] In other embodiments, the formulations described herein are delivered using a pulsatile dosage form. A pulsatile dosage form is capable of providing one or more immediate release pulses at predetermined time points after a controlled lag time or at specific sites. Exemplary pulsatile dosage forms and methods of their manufacture are disclosed in U.S. Pat. Nos. 5,011,692, 5,017,381, 5,229,135, 5,840,329 and 5,837,284. In one embodiment, the pulsatile dosage form includes at least two groups of particles, (i.e. multiparticulate) each containing the formulation described herein. The first group of particles provides a substantially immediate dose of a therapeutic agent upon ingestion by a mammal.

The first group of particles can be either uncoated or include a coating and/or sealant. In one aspect, the second group of particles comprises coated particles. The coating on the second group of particles provides a delay of from about 2 hours to about 7 hours following ingestion before release of the second dose. Suitable coatings for pharmaceutical compositions are described herein or known in the art.

[00195] In some embodiments, pharmaceutical formulations are provided that include particles of a therapeutic agent and at least one dispersing agent or suspending agent for oral administration to a subject. The formulations may be a powder and/or granules for suspension, and upon admixture with water, a substantially uniform suspension is obtained.

[00196] In some embodiments, particles formulated for controlled release are incorporated in a gel or a patch or a wound dressing.

[00197] In one aspect, liquid formulation dosage forms for oral administration and/or for topical administration as a wash are in the form of aqueous suspensions selected from the group including, but not limited to, pharmaceutically acceptable aqueous oral dispersions, emulsions, solutions, elixirs, gels, and syrups.

In addition to the particles of a therapeutic agent, the liquid dosage forms include additives, such as: (a) disintegrating agents; (b) dispersing agents; (c) wetting agents; (d) at least one preservative, (e) viscosity enhancing agents, (f) at least one sweetening agent, and (g) at least one flavoring agent. In some embodiments, the aqueous dispersions can further include a crystalline inhibitor.

[00198] In some embodiments, the liquid formulations also include inert diluents commonly used in the art, such as water or other solvents, solubilizing agents, and emulsifiers.

The decrease can be, for example, at least 10%, at least 20%, at least 30%, at least 40% or more, and is preferably down to a level accepted as within the range of normal for an individual without a given disease.

[00253] The terms“subject” encompass mammals. Non-limiting examples of mammal include, any member of the mammalian class: humans, non-human primates such as chimpanzees, and other apes and monkey species; farm animals such as cattle, horses, sheep, goats, swine; domestic animals such as rabbits, dogs, and cats; laboratory animals including rodents, such as rats, mice and guinea pigs, and the like. In one aspect, the mammal is a human. The term“animal” as used herein comprises human beings and non human animals. In one embodiment, a“non-human animal” is a mammal, for example a rodent such as rat or a mouse. In some instances, a human subject is a“patient,” which as used herein, refers to a subject who may be diagnosed with a disease or condition disclosed herein.

[00254] The term“gene,” as used herein, refers to a segment of nucleic acid that encodes an individual protein or RNA (also referred to as a“coding sequence” or“coding region”), optionally together with associated regulatory region such as promoter, operator, terminator and the like, which may be located upstream or downstream of the coding sequence. A“genetic locus” referred to herein, is a particular location within a gene.

[00255] The term,“genotype” as disclosed herein, refers to the chemical composition of polynucleotide sequences within the genome of an individual. In some embodiments, the genotype comprises a single nucleotide polymorphism (SNP) or and indel (insertion or deletion, of a nucleobase within a

polynucleotide sequence). In some embodiments, a genotype for a particular SNP, or indel is

heterozygous. In some embodiments, a genotype for a particular SNP, or indel is homozygous.

[00256] A“polymorphism” as used herein refers to an aberration in (e.g., a mutation), or of (e.g., insertion/deletion), a nucleic acid sequence, as compared to the nucleic acid sequence in a reference population. In some embodiments, the polymorphism is common in the reference population. In some embodiments, the polymorphism is rare in the reference population.

[00257] The term,“single nucleotide polymorphism” or SNP as disclosed herein, refers to a variation in a single nucleotide within a polynucleotide sequence. The term should not be interpreted as placing a restriction on a frequency of the SNP in a given population. The variation of an SNP may have multiple different forms. A single form of an SNP is referred to as an“allele.” An SNP can be mono-, bi-, tri, or tetra-allelic. A SNP may include a“risk allele,” a“protective allele,” or neither. By way of example, a reference polynucleotide sequence reading 5’ to 3’ is TTACG. A SNP at allele position 3 (of 5’-TTACG- 3’) comprise a substitution of the reference allele,“A” to a non -reference allele,“C.” If the“C” allele of the SNP is associated with an increased probability of developing a phenotypic trait, the allele is considered a“risk” allele. However, the same SNP may also comprise a substitution of the“A” allele to a “T” allele at position 3. If the T allele of the SNP is associated with a decreased probability of developing a phenotypic trait, the allele is considered a“protective” allele. The SNP may be observed in at least 1% of a given population. In some embodiments, the SNP is represented by an“rs” number, which refers to the accession of reference cluster of one more submitted SNPs in the dbSNP bioinformatics database as of the fding date of this patent application, and which is included within a sequence that comprises the total number of nucleobases from 5’ to 3’. In some embodiments, a SNP may be further defined by the position of the SNP (nucleobase) within the dbSNP sequence, the position of which is always with reference to 5’ length of the sequence plus 1. In some embodiments, a SNP is defined as the genomic position in a reference genome and the allele change (e.g. chromosome 7 at position 234,123,567 from G allele to A allele in the reference human genome build 37). In some embodiments, the SNV is defined as the genomic position identified with [brackets] or an“N” in a sequence disclosed herein.

[00258] The term,“indel,” as disclosed herein, refers to an insertion, or a deletion, of a nucleobase within a polynucleotide sequence. An indel can be mono-, bi-, tri, or tetra-allelic. An indel may be“risk,” a“protective,” or neither, for a phenotypic trait. In some embodiments, the indel is represented by an“rs” number, which refers to the accession of reference cluster of one more submitted indels in the dbSNP bioinformatics database as of the filing date of this patent application, and which is included in a sequence that comprises the total number of nucleobases from 5’ to 3’. In some embodiments, an indel may be further defined by the position of the insertion/deletion within the dbSNP sequence, the position of which is always with reference to the 5’ length of the sequence plus 1. In some embodiments, an indel is defined as the genomic position in a reference genome and the allele change. In some embodiments, the indel is defined as the genomic position identified with [brackets] or an“N” in a sequence disclosed herein.

[00259] “Haplotype” as used herein, encompasses a group of one or more genotypes, which tend to be inherited together in a reference population. In some embodiments, a haplotype comprises particular polymorphism or another polymophism in linkage disequilibrium (LD) therewith.

[00260] “Linkage disequilibrium,” or“LD,” as used herein refers to the non-random association of alleles or indels in different gene loci in a given population. LD may be defined by a D’ value

corresponding to the difference between an observed and expected allele or indel frequencies in the population (D=Pab-PaPb), which is scaled by the theoretical maximum value of D. LD may be defined by an r ² value corresponding to the difference between an observed and expected unit of risk frequencies in the population (D=Pab-PaPb), which is scaled by the individual frequencies of the different loci. In some embodiments, D’ comprises at least 0.20. In some embodiments, r ² comprises at least 0.70.

Example 1: Identification of Genotypes

[00273] Patients with IBD were recruited at the Cedars-Sinai Inflammatory Bowel Disease Centers. The diagnosis of each patient was based on standard endoscopic, histologic, and radiographic features. Blood samples were collected from patients at the time of enrollment. Blood samples were also collected from individuals without IBD. Genotyping was performed at Cedars-Sinai Medical Center using Illumina whole-genome arrays per manufacturer’s protocol (Illumina, San Diego, CA) on all samples collected. Markers/SNPs were excluded from analysis if: there were deviations in Hardy-Wemberg Equilibrium in controls with p < 0.0001; missingness in SNPs > 2% and minor allele frequency < 1%. Related individuals (Pi-hat scores >0.25) were identified using identity-by-descent and excluded from analysis (PLINK). Admixture was used to generate ethnicity proportion estimations for all individuals. Only subjects identified by admixture as Caucasian (proportion <0.75) were included in the analysis.

[00274] Multiple large-scale case-control association studies involving Inflammatory Bowel Disease (IBD) Crohn’s disease (CD), and ulcerative colitis (UC) in Caucasian populations using gene-based single nucleotide polymorphism (SNP) markers were performed. The studies included patients recruited at the Cedars-Sinai Inflammatory Bowel Disease Centers with Inflammatory Bowel Disease (IBD) (n=9360), Crohn’s disease (CD)(n=7965), and ulcerative colitis (UC) (n=6864). The studies also included GWAS data derived from the International Inflammatory Bowel Diseases Genetic Consortium (IIBDGC). A P value cutoff of 0.05 was used. Table 2 provides SNPs identified as being associated with IBD. Table 1 provides SNPs identified as being associated with CD. Table 3 provides SNPs identified as being associated with UC. The allele“A” within rs911605 (rs911605A) SNP was show to be significantly associated with IBD ( =5.21xl0 ⁴ ), Crohn’s disease (CD) (r/ ^J = 1 .70x 10’ ^’ ') and ulcerative colitis (UC) (T=4.54xlO ² ).The rsl006026G was show to be moderately associated with IBD (T=6.67xl0 ¹ ), CD (T=4.43xl0 ^_1 ), and UC ( =8.92xl0 ¹ ).

Example 2: eQTL in Small Bowel Resection Identifies Polymorphisms as Functionally Related to CD30L Protein Expression

[00275] 85 Caucasian patients with Crohn’s disease (CD) who underwent small bowel resection were recruited at the Cedars-Sinai Inflammatory Bowel Disease Centers. The diagnosis of each patient was based on standard endoscopic, histologic, and radiographic features. Patients were selected based on being diagnosed with CD and having undergone small bowel resection for disease. Tissue biopsy samples were collected from uninvolved tissue sections taken from small bowel resection after surgery. Expression Quantitative Trait Loci Mapping (eQTL) was performed on these samples. Table 13 provides polymorphisms associated with a decrease in CD30. Table 14 provides polymorphisms associated with an increase in CD30. Negative beta values represent a decrease in gene expression, whereas positive beta values represent an increase in gene expression, in the tissue samples. Positive beta values were observed for the polymorphisms rs911605 (SEQ ID NO: 2) and rsl006026 (SEQ ID NO: 4). FIG 1 shows that the risk allele,“A” within rs9H605 (E^AIcIO ⁴ ) - rs911605A (X=l) or rs9H605AA (X=2) is associated with increased expression of TNFSF8 mRNA in the small bowel using cis-eQTL, as compared to individuals who do not carry the risk allele, or“non-risk, GG” (X=0). Without being bound by any particular theory, this is highly suggestive that expression of these polymorphisms is associated with increased CD30L protein expression in subjects with CD. Increased CD30L is defined as +2 standard deviation over the mean CD30L level of a control derived from a non-diseased individual or population of non-diseased individuals.

Example 3. Polymorphism Expression Effects Expression and Function of CD30L and Pro- Inflammatory Cytokines in Peripheral Blood

[00276] Patients with Crohn’s Disease (CD) were recruited at the Cedars-Sinai Inflammatory Bowel Disease Centers. The diagnosis of each patient was based on standard endoscopic, histologic, and radiographic features. Patients were selected based on being diagnosed with CD. Samples of peripheral blood were collected from patients at the time of enrollment. Penpheral blood mononuclear cells (PBMC) were isolated on standard Ficoll-Hypaque density gradients. PBMC were stimulated in vitro under conditions that would up-regulate either CD30L (phorbol 12-myristate 13-acetate (PMA) and ionomycin) or CD30 (anti-CD3 antibody and anti-CD28 antibody) for 72 hours. Supernatants were collected for analysis of cytokines at 6, 24 and 72, hours and cells were collected after 72 hours and analyzed for expression of CD30 and CD30L by flow cytometry. Both T and B cells expressed increased levels of CD30L in subjects that carried (either homozygous or heterozygous) the risk polymorphism for rs911605 (rs911605A or rs911605AA) (FIG. 2). Analysis of TNF-alpha, interleukin 6 (IL-6), and interferon- gamma (IFN-gamma) in the supernatants from cultures showed that cells from patients that carried the polymorphism for rs911605 produced elevated levels of pro -inflammatory cytokines following stimulation (FIGS. 3-5). Without being bound by any particular theory, these findings are highly suggestive that the genotype comprising rs911605A or rs911605AA is correlated with an increase in expression of CD30L and pro-inflammatory cytokines involved in the pathogenesis of IBD.

Example 4. Soluble CD30 (sCD30) Levels Correlate with CD30L Expression on T and B Cells in Subject Carrying Refined Patient Selection Genotypes

[00277] PBMC were stimulated in vitro under conditions that would up-regulate either CD30L (phorbol 12-myristate 13-acetate (PMA) and ionomycin) or CD30 (anti-CD3 antibody and anti-CD28 antibody) for 72 hours. Supernatants were collected for analysis of sCD30 at 72, hours and cells were collected after 72 hours and analyzed for expression of CD30 and CD30L by flow cytometry. Analysis showed that sCD30 levels correlate with CD30L expression on T and B cells in the genetically refined patient population (rs911605AA+ rsl006026GG). FIG. 6A shows sCD30 levels correlate with CD30L expression on T cells in the genetically refined patient population defined by rs9H605AA + rsl006026AA/GA/GG. FIG. 6B shows sCD30 levels correlate with CD30F expression on T cells in the genetically refined patient population defined by rs9H605AA + rsl006026GA/GG. FIG. 6C shows sCD30 levels correlate with CD30L expression on T cells in the genetically refined patient population defined by rs911605AA + rsl006026GG. FIG. 7A shows sCD30 levels correlate with CD30L expression on B cells in the genetically refined patient population defined by rs911605AA + rsl006026AA/GA/GG. FIG. 7B shows sCD30 levels correlate with CD30L expression on B cells in the genetically refined patient population defined by rs911605AA + rsl006026GA/GG. FIG. 7C shows sCD30 levels correlate with CD30L expression on B cells in the genetically refined patient population defined by rs9H605AA + rsl006026GG.

[00278] Patients with IBD were recruited at the Cedars-Sinai Inflammatory Bowel Disease Centers. The diagnosis of each patient was based on standard endoscopic, histologic, and radiographic features. Blood samples were collected from patients at the time of enrollment. Blood samples were also collected from individuals without IBD. Genotyping was performed at Cedars-Sinai Medical Center using Illumina whole-genome arrays per manufacturer’s protocol (Illumina, San Diego, CA) on all samples collected. Markers/SNPs were excluded from analysis if: there were deviations in Hardy-Wemberg Equilibrium in controls with p < 0.0001; missingness in SNPs > 2% and minor allele frequency < 1%. Related individuals (Pi-hat scores >0.25) were identified using identity-by-descent and excluded from analysis (PLINK). Admixture was used to generate ethnicity proportion estimations for all individuals. Only subjects identified by admixture as Caucasian (proportion <0.75) were included in the analysis.

[00279] Polymorphisms Associated with Serologies

[00280] Serum samples were obtained from all patients and tested for the presence of antibodies against Saccharomyces cerevisiae (ASCA), and Cbirl flagellin. Genotyping was performed at Cedars-Sinai Medical Center using Illumina whole-genome arrays per manufacturer’s protocol (Illumina, San Diego, CA) on blood samples collected from the patients.

Example 8. Quantification of Soluble CD30

[00297] The quantity of soluble CD30 is determined from a sample of serum from a subject. The assay employs an antibody specific for human CD30 coated on a 96- well plate. Standards and the sample from the subject are pipetted into the wells and CD30 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human CD30 antibody is added.

After washing away unbound biotinylated antibody, HRP -conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of CD30 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm. The quantity of CD30 in the sample from the subject is determined by comparison to a standard curve. The subject is treated if he has an elevated level of CD30, which may be defined by + 2 standard deviation above the mean for a control derived from a non-diseased individual, or population of non-diseased individuals.

Example 9. Treatment with anti-CD30L Antibody

[00300] Single ascending dose (SAD) arms: Subjects in each group (subjects are grouped based on the presence or absence of rs911605 A genotype) receive either a single dose of the antibody or a placebo. Exemplary doses are 1, 3, 10, 30, 100, 300, 600 and 800 mg of antibody. Safety monitoring and PK assessments are performed for a predetermined time. Based on evaluation of the PK data, and if the antibody is deemed to be well tolerated, dose escalation occurs, either within the same groups or a further group of healthy subjects. Dose escalation continues until the maximum dose has been attained unless predefined maximum exposure is reached or intolerable side effects become apparent.

[00301] Multiple ascending dose (MAD) arms: Subjects in each group (subjects are grouped based on the presence or absence of rs911605A genotype) receive multiple doses of the antibody or a placebo. The dose levels and dosing intervals are selected as those that are predicted to be safe from the SAD data.

Dose levels and dosing frequency are chosen to achieve therapeutic drug levels within the systemic circulation that are maintained at steady state for several days to allow appropriate safety parameters to be monitored. Samples are collected and analyzed to determination PK profiles.

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drag. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed. Multiple Ascending Dose First Dose: Volume of Distribution at Steady State (Vss) [Time Frame: 12 weeks]. Volume of distribution is defined as the theoretical volume in which the total amount of drag would need to be uniformly distributed to produce the desired blood concentration of a drag. Steady state volume of distribution (Vss) is the apparent volume of distribution at steady-state. Multiple Ascending Dose First Dose: Apparent Oral Clearance (CL/F) [Time Frame: 12 weeks] . Clearance of a drag is a measure of the rate at which a drag is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance is estimated from population pharmacokinetic (PK) modeling. Drag clearance is a quantitative measure of the rate at which a drag substance is removed from the blood. Multiple Ascending Dose First Dose: Systemic Clearance (CL) [Time Frame: 12 weeks] CL is a quantitative measure of the rate at which a drag substance is removed from the body.

Example 11: Phase IB Clinical Trial

[00311] A phase lb open label clinical trial is performed to evaluate efficacy of an anti-CD30L antibody on patients having a rs911605A genotype (carrier of“A” at position 501 of SEQ ID NO: 1) and obstructive Crohn’s disease.

[00312] Arms: 10 patients positive for rs911605 A are administered the antibody. 5-10 patients negative for rs911605A are administered the antibody. Patients are monitored in real-time. Central ready of endoscopy and biopsy is employed, with readers blinded to point of time of treatment and endpoints.

[00313] Inclusion Criteria: Two groups of subjects are selected: subjects having rs911605A genotype, and subjects lacking rs911605 A genotype.

[00314] Primary Outcome Measures: Simple Endoscopic Score for Crohn’s Disease (SESCD),

Crohn's Disease Activity Index (CDAI), and Patient Reported Outcome (PRO). If the rs911605 A genotype positive group shows 50% reduction from baseline, a Phase 2a clinical trial is performed.

[00315] Inclusion Criteria: PRO entry criteria: Abdominal pain score of 2 or more and/or stool frequency score of 4 or more. Primary outcome would be pain core of 0 or 1 and stool frequency score of 3 or less with no worsening from baseline. Endoscopy entry criteria: SESCD ileum only entry at score of

4 and 6 if colon is involved. Primary endoscopic outcome is 40-50% delta of mean SESCD.

Example 12: Phase 2A Clinical Trial

[00316] A phase 2a clinical trial is performed to evaluate efficacy of an anti-CD30L antibody on patients having a rs9l 1605A genotype (carrier of“A” at position 501 of SEQ ID NO: 1) and obstructive Crohn’s disease.

[00317] Arms: 40 patients per arm (antibody and placebo arms) are treated with antibody or placebo for 12 weeks. An interim analysis is performed after 20 patients from each group are treated at the highest dose to look for a 40-50% delta between placebo and treated group in primary outcome (50% reduction from baseline in SESCD, CDAI, and PRO).

[00318] Primary Outcome Measures: Simple Endoscopic Score for Crohn’s Disease (SESCD), Crohn's Disease Activity Index (CDAI), and Patient Reported Outcome (PRO).
