Description

[0001] PAT059980-WO-PCT DOSAGE FORMS COMPRISING A VAV1 DEGRADER TECHNICAL FIELD Disclosed herein are dosage forms comprising a chemical entity (e.g. a compound or a pharmaceutically acceptable salt thereof) that degrades human proto-oncogene VAV1 protein (VAV1). More specifically, disclosed herein are dosage forms comprising a VAV1 degrader which is 3-(2-chloro-4'-(2-oxopyridin-1(2H)-yl)-[1,1'-biphenyl]-3-yl)piperidine-2,6-dione or a pharmaceutically acceptable salt thereof. These dosage forms are useful, e.g., for treating a subject (e.g., a human subject) having a disorder or disease that can be treated by reducing the level of VAV1, for example an inflammatory or autoimmune disorder, a transplantation setting disorder, or a cancer. BACKGROUND The ubiquitin proteasome system can be manipulated with different small molecules to trigger targeted degradation of specific proteins of interest. Promoting the targeted degradation of proteins using small molecule degraders is emerging as a new modality in the treatment of diseases. One such modality relies on redirecting the activity of E3 ligases such as cereblon (a phenomenon known as E3 reprogramming) using low molecular weight compounds, which have been termed molecular glues (also called molecular glue degraders; “MGDs”), to promote the poly-ubiquitination and ultimately proteasomal degradation of new protein substrates involved in the development of diseases. Molecular glues bind to both the E3 ligase and the target protein. It is believed that the interaction between the molecular glue and the E3 ligase creates a surface that promotes formation of a complex with the target protein, permitting subsequent degradation of the target protein. Examples of molecular glues for the E3 ligase cereblon include: Thalidomide, Lenalidomide and Pomalidomide, all of which are immunomodulatory imide drugs (IMiDs) approved by the FDA for use in hematological cancers. VAV family proteins, including VAV1, VAV2 and VAV3, are guanine nucleotide exchange factors (GEFs) for Rho family GTPases. VAV1 is a 95 kDa protein that is a positive regulator of T cell receptor and B cell receptor signaling. VAV1 expression is normally highly restricted to hematopoietic cells. VAV1 becomes rapidly phosphorylated on tyrosine in response to a variety of stimuli, including stimulation of T-cell receptor (TCR), B cell receptor (BCR), and various cytokine receptors. VAV1 regulates multiple cellular functions and signaling pathways in hematopoietic-derived cells (e.g., T- and B-cells, natural killer cells, and osteoclasts) through activation of certain GTPases. VAV1-mediated functions include gene transcription, development PAT059980-WO-PCT and activation of immune cells (e.g., T- and B-cells). VAV1 is a positive regulator of (TCR) signaling including nuclear factor of activated T cells (NFAT), interferon gamma (IFNɣ) and Interleukin-2 (IL-2) cytokine secretion. Knock-in mice having a mutated VAV1 with disrupted GEF activity, but intact GEF- independent function, show reduced T cells proliferation and activation in response to allogeneic stimulation and showed reduced expansion of T cells in a systemic graft-versus-host model (Haubert et al. 2012 Transplantation Immunology 26: 212, 2012). VAV1 deficient mice are resistant to MOG(5-55)-induced experimental autoimmune encephalomyelitis (EAE), a commonly used model of multiple sclerosis (Korn et al. 2003 Journal of Neuroimmunology 139:17). Finally, genome-wide CRISPR activation (CRISPRa) and interference (CRISPRi) screens in primary human T cells identified VAV1 as an important positive regulator of T cell function (Schmidt et al.2022 Science 375:6580). In summary, VAV1 is a dominant signal transduction protein in the adaptive immune system. It is a positive regulator of immune receptor signaling in both T cells and B cells. Thus, reduction in VAV1 can reduce immune cell activation, immune cell proliferation and the production of various cytokines. For at least these reasons, degradation of VAV1 can be therapeutically beneficial in a variety of disease conditions. PCT / US2024 / 010733 discloses chemical entities (e.g., a compound or a pharmaceutically acceptable salt thereof) that degrade and / or otherwise inhibit human Proto-oncogene VAV 1 protein (VAV1). These chemical entities are useful, e.g., for treating a subject (e.g., a human subject) having a disorder or disease that can be treated by reducing the level of VAV1, thereby reducing VAV activity in cells. By reducing the level of VAV1, the chemical entities can reduce signaling in certain immune cell activation pathways. For example, the chemical entities may be used to reduce inflammation or autoimmune activity, and thus the chemical entities are useful for treating a subject having an inflammatory or autoimmune disorder. They may be useful for treating, for example, multiple sclerosis, rheumatoid arthritis, myasthenia gravis, chronic lymphocytic leukemia, ulcerative colitis, psoriasis, cutaneous lupus, axial spondyloarthritis, and graft versus host disease. The chemical entities are also useful, e.g., for treating a subject (e.g., a human subject) having a disorder or disease that is associated with VAV1 polymorphisms or dysregulated lymphocyte (e.g., T-cell). Amongst the chemical entities disclosed in PCT / US2024 / 010733 is 3-(2-chloro-4'-(2- oxopyridin-1(2H)-yl)-[1,1'-biphenyl]-3-yl)piperidine-2,6-dione. This compound is described herein as Compound A.

Ideally, such dosage forms will have advantageous characteristics such as long-term physical and chemical stability, uniformity, and suitability to facilitate delivery of the active ingredient to the target site in the subject to whom the dosage form is to be administered. Dosage form design can also contribute to improved bioavailability of the active ingredient. In addition, there is a desire for dosage forms that contain a precisely known amount of Compound A, as such dosage forms can facilitate accurate dosing. This is especially important because of the high potency of Compound A.

DESCRIPTION OF DRAWINGS FIG. 1 is a schematic depiction of certain aspects of VAV1’s relationship to certain proteins involved in T cell receptor activation. VAV1 is a positive regular of T cell receptor signaling, including interferon gamma production and IL-2 secretion. FIG.2A shows dose-dependent decrease in VAV1 levels in primary human T-cells upon 24h treatment with Compound A relative to DMSO control as assessed by flow cytometry (y-axis represents normalized VAV1 levels relative to DMSO control; x-axis depicts doses of Compound A). FIG. 2B shows that VAV1 is significantly and selectively degraded by Compound A in Jurkat cells following 24h treatment as assessed by quantitative TMT proteomics (y-axis represents confidence p-value [-log10]; x-axis represents protein fold-change [log2] relative to DMSO control samples). FIGS. 3A-3C show that VAV1 degradation results in inhibition of various hallmarks of TCR-mediated activity following TCR stimulation of primary human T-cells. Cells were treated with Compound A for 24h followed by TCR stimulation (anti-CD3 / anti-CD28 antibodies). CD69 surface expression (24 hr), IL-2 secretion (48 hr), and proliferation (96 hr) were evaluated at various timepoints following TCR stimulation (y-axis depicts percent of CD69 activation, IL-2 secretion, or proliferation relative to TCR-stimulated DMSO control; x-axis depicts doses of Compound A). FIG. 4 shows the concentration of Compound A in plasma over time and associated decrease in normalized VAV1 to b-actin protein levels relative to pre-treatment after a single oral dose of Compound A at 10 mg / kg (y-axis represents hours post one single oral dose of Compound A [hour]; left y-axis represents the concentration of Compound A in ng / ml in plasma, filled PAT059980-WO-PCT rhombi; right y-axis represents percentage [%] VAV1 protein levels normalized to b-actin protein levels and relative to pre-dose in blood cells, filled triangles). FIG.5 shows that oral administration of Compound A in a MOG35-55-induced experimental autoimmune encephalomyelitis (EAE) model led to inhibition of disease progression. Mice were immunized by subcutaneous injection at day 0 with an emulsified mixture consisting of the synthetic peptide derived from myelin oligodendrocyte glycoprotein (MOG35-55) and M. tuberculosis mixed with incomplete Freund’s adjuvant. Additionally, mice were injected intraperitoneally with pertussis toxin at 0 and 48 hours. Mice were followed for development of symptoms and scored for EAE clinical signs disease (0=no signs of disease; 1=limp tail or hind limb weakness; 2=limp tail and hind limb weakness; 3=partial hind limb paralysis; 4=complete hind limb paralysis; 5=moribund), once a day (QD) dosing started at day 12 and ended at day 18. Dexamethasone dosed QD orally from day 12 to day 18 was used as comparative treatment. 10 mg / kg Compound A prevented the progression of EAE disease as it was observed for the mice treated with Dexamethasone at 1 mg / kg (x-axis represents days post immunization initiation [days]; y-axis represents clinical EAE score, [mean ±SEM]; empty circle: vehicle, PO, QD; filled triangles inverted: Compound A 10 mg / kg, PO, QD; filled square: Dexamethasone 1 mg / kg, PO, QD). FIG. 6A shows that oral administration of Compound A in a MOG35-55-induced experimental autoimmune encephalomyelitis (EAE) model led to inhibition of disease progression in a dose-dependent manner. Mice were immunized by subcutaneous injection at day -12 with an emulsified mixture consisting of the synthetic peptide derived from myelin oligodendrocyte glycoprotein (MOG35-55) and M. tuberculosis mixed with incomplete Freund’s adjuvant. Additionally, mice were injected intraperitoneally with pertussis toxin at day -12 and -10. Mice were followed for development of symptoms and scored for EAE clinical signs disease (0=no signs of disease; 1=limp tail or hind limb weakness; 2=limp tail and hind limb weakness; 3=partial hind limb paralysis; 4=complete hind limb paralysis; 5=moribund) every 3 days until day 0. Dosing started at day 0 and ended at day 13 with vehicle (PO, QD), dexamethasone (1 mg / kg, PO QD), and Compound A (1, 0.1, 0.01 mg / kg, PO, QD). 1 mg / kg Compound A prevented the progression of EAE disease as it was observed for the mice treated with Dexamethasone at 1 mg / kg (x-axis represents days post immunization initiation [days]; y- axis represents clinical EAE score, [mean ±SEM]; closed circle: vehicle; solid up triangle: Compound A 1 mg / kg; closed down triangle: Compound A 0.1 mg / kg; open up triangle: Compound A 0.01 mg / kg; open circle: Dexamethasone 1 mg / kg). PAT059980-WO-PCT FIG.6B shows that oral administration of Compound A degraded VAV1 in the spinal cord in a dose-dependent manner commensurate with reduction in clinical scores. On day 6, 4 mice per group were euthanized, spinal cords were excised and homogenized, and western blot was then used to assess VAV1 levels normalized to β-actin and shown relative to vehicle treated mice. Statistical analysis was performed using a one-way ANOVA with Dunnett’s multiple comparisons. ns = not significant, ***p<0.001, ****p<0.0001. FIG.7 shows that oral administration of Compound A in a T-cell transfer induced model of colitis led to inhibition of disease progression. CD17-SCID mice were injected intraperitoneally with 0.5 x 106non-pathogenic activated CD45RBlow(no disease control group) or pathogenic naïve CD45RBhigh (treatment groups) CD4+ T cells. From the day of cell transfer (day 0), the mice were monitored daily for disease activity index (DAI) comprising weight loss and stool consistency assessment. On day 0, two hours post-cell transfer, mice were treated orally (PO) daily (QD) with vehicle or Compound A 1 mg / kg for 42 days. 1 mg / kg Compound A prevented the progression of colitis (x-axis represents days post disease induction and treatment start [days]; y axis represents DAI score [mean ± SEM]; open circles, non-pathogenic control; closed black circles, vehicle; closed triangles, Compound A 1 mg / kg). FIG. 8A shows that oral administration of Compound A in a collagen-induced arthritis model led to inhibition of disease progression. To induce collagen-induced arthritis (CIA), fifteen DBA / 1 mice were injected intravenously with an emulsified mixture consisting of 100 μg of chicken collagen II emulsified in incomplete Freund’s adjuvant then 18 days later injected subcutaneously with chicken collagen II emulsified in complete Freund’s adjuvant. This immunization induces the activation and expansion of collagen specific T- and B-cells that migrate into the paw joints. Once in the paw joints, the activated T-cells induce destruction of the joint and bone tissue, leading to redness and swelling of the phalanges, and B-cells produce antibodies against collagen II. Following the second immunization, mice were monitored daily for clinical signs of disease as follows: 0=erythema and redness; 1=Erythema or mild redness near ear the tarsal, ankle, or metatarsal or one toe with erythema and redness; 2=Ankles and metatarsals are slightly erythematous and swollen with two or more toes with erythema and redness; 3=Moderate erythema and swelling of the ankle, wrists, and metatarsals; 4=Ankles, wrists, metatarsals, and toes are severely red and swollen. Upon disease onset, mice were randomly enrolled into treatment groups: vehicle (PO, QD), anti-TNF (10 mg / kg, IP, Q3D), or Compound A (1 mg / kg, PO, QD) and treated for 21 days. 1 mg / kg Compound A prevented the progression of arthritis (x-axis represents days post disease onset and treatment start [days]; y axis represents clinical score [mean ± SEM]; circles, vehicle; triangles, Compound A 1 mg / kg). PAT059980-WO-PCT FIG. 8B shows that oral administration of Compound A in a collagen-induced arthritis model led to decreased production of anti-collagen II IgG1 antibodies. At the end of the study, serum was collected and the amount of anti-collagen II IgG1 antibodies was measured by ELISA. Statistical analysis was performed using an unpaired two-tailed t-test. *p<0.05. FIG. 9 depicts VAV1 as a key mediator downstream of the B-cell receptor (BCR). Hallmarks of BCR pathway engagement include CD69 surface activation and secretion of IL-6 and IgG. FIGs. 10A-10C show that Compound A-mediated degradation of VAV1 reduces BCR- mediated CD69 expression and secretion of IL-6 and IgG of primary human B cells. Purified human primary B-cells were treated with Compound A 24 hrs followed by stimulation with anti- IgM and recombinant human IL-4 for 24 hours (for CD69 expression and IL-6 secretion) or with anti-IgM, BAFF, IL-21, and sCD40L for 5 days (for IgG secretion). FIG. 10A shows CD69 expression which was then assessed on CD19+ B cells by flow cytometry. CD69 expression is shown as a percentage (%) change relative to stimulated DMSO controls. Y-axis shows relative percentage of CD19+ B cells expressing CD69 and x-axis shows concentration of Compound A. FIG.10B shows IL-6 secretion which was assessed in the supernatant by alphalisa. IL-6 secretion is shown as a percentage (%) change relative to stimulated DMSO controls. Y-axis shows relative percentage of IL-6 level and x-axis shows concentration of Compound A. FIG.10C shows IgG secretion was assessed in the supernatant by alphalisa. IgG secretion is shown as a percentage (%) change relative to stimulated DMSO controls. Y-axis shows relative percentage of IgG level and x-axis shows concentration of Compound A. FIG.11 shows that Compound A treatment of selected B-cell lymphoma cell lines decrease growth with increasing concentration. REC-1, OCI-LY10, and SLVL cells were treated for 5 days with the indicated concentrations of Compound A. At 5 days of treatment, cell growth was measured by cell titer glow and normalized to T0 and DMSO. FIG. 12 shows that Compound A treatment of subcutaneously implanted REC-1 CDX decreases growth in vivo. CB17 SCID mice (10 per group) were inoculated subcutaneously on the right flank with 5x106REC-1 cells. After the average tumor volume of all mice reached 100-150 mm3, mice were treated with either vehicle or 10mg / kg Compound A PO QD. At indicated days post treatment initiation, tumor volume was measured. Mice were sacrificed when tumor volume reached 2000 mm3. PAT059980-WO-PCT FIG. 13 shows an X-ray powder diffraction (XRPD) pattern of crystalline form A of Compound A. FIG. 14 shows the results of an experiment to assess the amorphous solubility of Compound A in various polymers in FaSSIF medium. Amorphous solubilities were determined based on the onset of liquid-liquid phase separation using a solvent-shift UV assay. FIG.15 shows the results of an experiment to assess the kinetic solubility of spray-dried dispersions 1-4 in biorelevant media (FaSSGF and FaSSIF). Solubilities were determined based on the onset of liquid-liquid phase separation using a solvent-shift UV assay. FIG.16 is a tabletability plot showing tensile strength vs compression strength for tablet formulations 4-6. FIG. 17 is a compactability plot showing tensile strength vs solid fraction for tablet formulations 4-6. FIG.18 shows the results of a two-step dissolution test of softgel fill formulations S2, S3, S5, and S6.

DETAILED DESCRIPTION The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features and advantages of the invention will be apparent from the description and drawings, and from the claims. All documents referred to herein are incorporated by reference in their entirety. Definitions As used herein, the term “comprising” is in inclusive term which indicates that certain elements are included in an embodiment, but does not exclude the presence of other elements. The terms “comprising”, “including”, and “containing” are used interchangeably herein. Conversely, the term “consisting of” would exclude the presence of elements other than those recited. The term “consisting essentially of” indicates that further elements may be included in the embodiment to the extent that these further elements do not materially alter the fundamental characteristics of the embodiment. Thus, the term “consisting essentially of” allows for minor variations or additions that do not substantially alter the core functionality of the embodiment. Where values are specified herein in the form of ranges, the range is always inclusive, i.e. it includes the endpoint stated. For example, up to 10% includes 10%, less than 10% also includes 10%, and between 10 % and 30% includes both 10% and 30%. The term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit / risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al., describes pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences (1977) 66:1–19. Pharmaceutically acceptable salts of the compounds of the present disclosure include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric PAT059980-WO-PCT acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2–hydroxy–ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2–naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3–phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p–toluenesulfonate, undecanoate, valerate salts, and the like. Pharmaceutically acceptable salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(C1–4alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. Similarly, the term “pharmaceutically acceptable excipient” refers to an excipient which is, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and is commensurate with a reasonable benefit / risk ratio. An “excipient” is an inactive substance included alongside the active substance in a pharmaceutical formulation. As used herein, “VAV1” refers to naturally occurring VAV1, also known as Vav or p95vav, (e.g. mammalian, preferably human (Homo sapiens) VAV1) and encompasses naturally occurring variants, such as allelic variants and splice variants, which retain VAV1 functional activity. A “subject” to which administration is contemplated includes, but is not limited to, humans (i.e., a male or female of any age group, e.g., a pediatric subject (e.g., infant, child, adolescent) or adult subject (e.g., young adult, middle–aged adult or senior adult)) and / or a non-human animal, e.g., a mammal such as primates (e.g., cynomolgus monkeys, rhesus monkeys), cattle, pigs, horses, sheep, goats, rodents, cats, and / or dogs. In certain preferred embodiments, the subject is a human. In some embodiments, the subject is a non-human animal. The terms “human,” “patient,” and “subject” are used interchangeably herein. Disease, disorder, and condition are used interchangeably herein. As used herein, and unless otherwise specified, the terms “treat,” “treating” and “treatment” contemplate an action that occurs while a subject is suffering from the specified PAT059980-WO-PCT disease, disorder or condition, which reduces the severity of the disease, disorder or condition, or retards or slows the progression of the disease, disorder or condition (“therapeutic treatment”). In general, the “effective amount” of a compound refers to an amount sufficient to elicit the desired biological response. As will be appreciated by those of ordinary skill in this art, the effective amount of a compound of the present disclosure may vary depending on such factors as the desired biological endpoint, the pharmacokinetics of the compound, the disease being treated, the mode of administration, and the age, health, and condition of the subject. As used herein, and unless otherwise specified, a “therapeutically effective amount” of a compound is an amount sufficient to provide a therapeutic benefit in the treatment of a disease, disorder or condition, or to delay or minimize one or more symptoms associated with the disease, disorder or condition. A therapeutically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment of the disease, disorder or condition. The term “therapeutically effective amount” can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of disease or condition, or enhances the therapeutic efficacy of another therapeutic agent. An “amorphous” solid is a solid that has no long-range order in the position of its molecules. In other words, the solid is not crystalline. As used herein, a “filler” is an excipient that is added to a tablet formulation to add bulk or volume. Diluents may also aid processing, for example, by providing improved physical properties such as flow, compressibility, and tablet hardness. The terms “filler” and “diluent” are used interchangeably. As used herein, a “glidant” is an excipient that is added to a powder formulation to improve its flowability. A glidant can reduce interparticle friction and enhances the ability of the powder to flow more smoothly, which helps to ensure uniformity in the weight and content of tablets and capsules. By improving powder flow, glidants help to prevent issues such as sticking, clumping, and inconsistent dosing. As used herein, a “disintegrant” is an excipient that is added to a tablet formulation to promote the breakup or disintegration of the tablet after administration. The role of a disintegrant is to promote rapid dissolution of the drug by ensuring that the tablet or capsule disintegrates into smaller fragments in the gastrointestinal tract, allowing for faster release and absorption of the active pharmaceutical ingredient (API). Disintegrants work by swelling, wicking, or through deformation, which disrupts the physical integrity of the dosage form. This process helps to ensure that the medication is effective and provides the intended therapeutic effect. As used herein, a “lubricant” is an excipient that is added to a tablet formulation to reduce adhesion of the tablet formulation to surfaces (such as the tableting equipment) and / or to reduce PAT059980-WO-PCT interparticle friction within the tablet formulation, which can aid compression of tablets and ejection of tablets from the tableting equipment. As used herein in the context of excipients for formulations of an active ingredient, an “antioxidant” is a substance used to inhibit oxidative degradation of the active ingredient and / or other excipients included in the formulation. Antioxidants help maintain the stability and potency of the pharmaceutical product by neutralizing free radicals and preventing oxidative reactions. As used herein, a “solubiliser” is an excipient that is added to a formulation to increase the solubility of another ingredient, typically the active ingredient, in aqueous or other solvent systems. Solubilizers help increase the bioavailability of the API by ensuring it is adequately dissolved in the gastrointestinal fluids or other target environments, thereby improving its absorption and therapeutic efficacy. As used herein, a “non-ionic surfactant” is an amphiphilic molecule having a hydrophobic portion and a hydrophilic portion connected by one or more linkers, which allows it to be a surface active molecule, that is substantially non-ionised (i.e. uncharged) in water at neutral pH. As used herein, the term “particle size” or “median particle size” refers to the volume distributed median particle diameter (equivalent spherical diameter corresponding to 50% of the volume of all the particles, read on the cumulative distribution curve relating volume % to the diameter of the particles – often referred to as the “D(v,0.5)” value). Particle size distributions can be determined by routine laser diffraction techniques. Unless otherwise stated, particle size distribution measurements as specified or reported herein are as measured by Malvern Instruments’ conventional Malvern Mastersizer 3000 particle size analyzer. As used herein to characterize certain types of hydroxypropylmethylcellulose (HPMC, also known as hypromellose) and HPMC derivatives, viscosity is determined as a 2 weight % solution in water at 20 °C as described in the United States Pharmacopeia (USP 35, "Hypromellose", pages 423-424 and 3467-3469). As described in USP 35, viscosities of up to 600 mPa-s are determined by Ubbelohde viscosity measurement and viscosities above 600 mPa-s are determined using a Brookfield viscometer.

The skilled person knows how to make dosage PAT059980-WO-PCT forms according to these embodiments, e.g. by selecting amounts of Compound A and various excipients which do not exceed the stated total weight of the dosage form. Preferably, the dosage form is a solid dosage form. As used herein, solid dosage forms are dosage forms that have a solid exterior. Thus, dosage forms that comprise a solid outer shell but have a liquid or semisolid interior (as is the case for softgel capsules), or that are hollow, are encompassed by the term “solid dosage form”. In some embodiments, the dosage form is a pill, tablet, capsule, or lozenge. In some embodiments, the dosage form is a pill, tablet, or capsule. In some embodiments, the dosage form is a tablet or a capsule. Solid dosage forms can be advantageous as, in general, solid dosage forms have a longer shelf life than liquid dosage forms, since drugs are generally more stable in the solid state and microbial growth is hindered. Solid dosage forms are also generally less bulky than liquid dosage forms, which is beneficial for transport and storage. In some embodiments, the dosage form is a liquid dosage form. In some embodiments, the dosage form is a unit dosage form. The term “unit dosage form” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect. Thus, unit dosage forms are useful for facilitating accurate dosing. Typical unit dosage forms include prefilled, premeasured ampules or syringes in the case of liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In addition to Compound A, the dosage forms provided herein comprise a pharmaceutically acceptable excipient. In some embodiments, the dosage form comprises two or more pharmaceutically acceptable excipients. In some embodiments, the dosage form comprises three or more pharmaceutically acceptable excipients. In some embodiments, the dosage form comprises four or more pharmaceutically acceptable excipients. In some embodiments, the dosage form comprises five or more pharmaceutically acceptable excipients. Tablets In some embodiments, the dosage form is a tablet. Preferably, the tablet comprises a solid dispersion as described below. Tablets typically contain one or more excipients selected from fillers / diluents, disintegrants, surfactants, binders, glidants, lubricants, colorants, and fragrances. Tablets may be prepared using conventional methods known to those skilled in the field of pharmaceutical formulation, for example as described in textbooks such as Remington: The PAT059980-WO-PCT Science and Practice of Pharmacy, 21st Ed., Lippincott Williams & Wilkins, Baltimore, Md. (2003); Ansel et al., Pharmaceutical Dosage Forms And Drug Delivery Systems, 7th Edition, Lippincott Williams & Wilkins, (1999); The Handbook of Pharmaceutical Excipients, 4th edition, Rowe et al., Eds., American Pharmaceuticals Association (2003); Gibson, Pharmaceutical Preformulation And Formulation, CRC Press (2001). For example, tablets can be prepared by compressing a powder or granular formulation, e.g. using a die punch. A granular formulation may be prepared by techniques that are well known to any person skilled in the art of pharmaceutical formulation, such as by wet granulation or dry granulation. Formulation of the API into granules can help to enhance the uniformity, flow, and compactability of the formulation.

EXAMPLE 2: BIOLOGICAL ACTIVITY DATA FOR COMPOUND A PAT059980-WO-PCT Example 2.1: VAV1 Degradation Assay A heterozygous VAV1 C-terminal HiBiT knock-in pool was generated at Monte Rosa Therapeutics from a clonal Jurkat cell stably expressing LgBiT and possessing a homozygous GSPT1-G575N mutation. Cells were plated at 10,000 cells per well using Multiflo (BioTek) or Multi Drop Combi (Thermo Fisher) in 384-well white solid bottom plates (Corning, 3570BC) in 25 ul volume in RPMI 1640 media (Thermo Fischer, 22400105) containing 10% FBS (Corning, 35-075-CV), 1% Peniciliin / Streptomycin (ThermoFisher Scientific, 15140-122), and 1% Endurazine (Nano-Glo Endurazine Live Cell Substrate (Promega, N2571)). Cells were incubated for ~16 hours at 37°C, 5% CO2.25nL of test compounds at 10 µM were dosed into the plate using an Echo® 650 liquid handler (Labcyte). Cells were incubated at 37 °C, 5% CO2 and signal was read at 6 and 24 hours after Compound Addition on a Pherastar FSX using “LUM plus” optic module. Analysis was performed in Scinamic (Scinamic, Cambridge, MA). Luminescence response (R) was calculated by the formula: response = 100 * (S - N) / (P-N) where S is the signal of the well, N and P the mean negative and positive control values respectively of the same plate. The luminescence response was then fitted in Scinamic using a 3-parameter agonist logistic fit (hillslope = 1, EC50 > 0, top / bottom unconstrained). Compound A was found to have a DC50 value of 7 nM, and a Dmax of 97%. Example 2.2: VAV1 Degradation in T cells Frozen human Pan T cells purchased from STEMCELL technologies were thawed, washed with 1X PBS & resuspended in complete cell culture medium (RPMI + 10% FBS). Cells were plated at optimized cell density in U-bottom 96 well plate (Costar , catalog number Z707899) and treated with Compound A using a serial dilution ranging from 0.1 nM to 1000 nM and including a DMSO control. Plates were incubated for 24 hrs at 5% CO2, 37°C. Cells were fixed and permeabilized and then washed 2x with BD stain buffer and stained with anti-VAV1 antibody (CST #2502) for 30 minutes at 4 C. Following staining with VAV1 antibody cells were washed with PBS and incubated with PE conjugated Anti-rabbit IgG (H+L), F(ab')2 Fragment (CST # 79408) secondary antibody for 20 minutes at 4°C. Following 2x PBS washes, the PE fluorophore signal intensity (VAV1) was evaluated by flow cytometry and data reported as Geometric Mean and normalized to DMSO control levels. The result of this study are shown in FIG.2A. Example 2.3: Selectivity of VAV1 Degradation in a Human T-lymphocyte Cell Line PAT059980-WO-PCT Jurkat cells (ATCC # TIB-152) were treated with either DMSO or Compound A at 10 µM for 24hr (2 replicates per condition). Proteins were extracted with the PreOmics iST-NHS lysis buffer (PreOmics #P.O.00030). The samples were then processed using the PreOmics kit following their recommended protocol with minor modifications. In brief, the proteins were reduced, alkylated and digested for 2h at 37°C. The peptides were then labelled with TMT reagent (1:4; peptide:TMT label) (Thermo Fisher Scientific). After quenching, the peptides were purified, and the 16 samples were combined to a 1:1 ratio. Mixed and labeled peptides were subjected to high-pH reversed-phase HPLC fractionation on an Agilent X-bridge C18 column (2.1 mm ID, 3.5 µm particles and 15 cm in length). Using an Agilent 1260 Infinity II LC system, a 60 min linear gradient from 0 % to 45 % 10 mM ammonium formate in 90% acetonitrile separated the peptide mixture into a total of 60 fractions, which were then consolidated into 24 fractions. The dried 24 fractions were reconstituted in 0.1 % formic acid for LC-MS3 analysis. Labelled peptides were loaded onto an Aurora column from Ionopticks (75 µm ID, 1.6 µm particles, 25 cm in length) in an EASY-nLC 1200 system. The peptides were separated using a 168 min gradient from 4 % to 30 % buffer B (80 % acetonitrile in 0.1% formic acid) equilibrated with buffer A (0.1 % formic acid) at a flow rate of 400 nl / min. Eluted TMT peptides were analyzed on an Orbitrap Eclipse mass spectrometer (Thermo Fisher Scientific). MS1 scans were acquired at resolution 120,000 with 400-1400 m / z scan range, AGC target 4x105, maximum injection time 50 ms. Then, MS2 precursors were isolated using the quadrupole (0.7 m / z window) with AGC 1x104 and maximum injection time 50 ms. Precursors were fragmented by CID at a normalized collision energy (NCE) of 35 % and analyzed in the ion trap. Following MS2, synchronous precursor selection (SPS) MS3 scans were collected by using high energy collision-induced dissociation (HCD) and fragments were analyzed using the Orbitrap (NCE 55 %, AGC target 1x105, maximum injection time 120 ms, resolution 60,000). The real- time search algorithm was used to trigger MS3 quantification scans. Protein identification and quantification were performed using Proteome Discoverer 2.4.0.305 with the SEQUEST algorithm and Uniprot human database (2021-01-29, 20614 protein sequences). Mass tolerance was set at 10 ppm for precursors and at 0.6 Da for fragment. Maximum of 3 missed cleavages were allowed. Methionine oxidation was set as dynamic modification, while TMT tags on peptide N termini / lysine residues and cysteine alkylation (+113.084) were set as static modifications. The list of identified peptide spectrum matches (PSMs) was filtered to respect a 1% False Discovery Rate (FDR) after excluding PSMs with TMT reporter ion signal-to-noise value lower than 5 and a precursor interference level value higher than 100%. Subsequently, protein identifications were inferred from protein specific peptides, i.e. peptides matching multiple protein entries were excluded. Protein relative quantification was PAT059980-WO-PCT performed using an in-house developed java script. This analysis included multiple steps; adjustment of reporter ion intensities for isotopic impurities according to the manufacturer’s instructions, global data normalization by equalizing the total reporter ion intensity across all channels, summation of reporter ion intensities per protein and channel, calculation of protein abundance log2 fold changes (L2FC) and testing for differential abundance using moderated t- statistics where the resulting p-values reflect the probability of detecting a given L2FC across sample conditions by chance alone. The results of this study are shown in FIG.2B. Example 2.4: Degradation of VAV1 results in inhibition of TCR-mediated CD69 activation, IL-2 secretion, and proliferation of Primary T-cells Frozen human Pan T cells purchased from STEMCELL technologies were thawed, washed with 1X PBS & resuspended in complete cell culture medium (RPMI+10% FBS). Cells were plated at optimized cell density in U-bottom 96 well plate (Costar, Z707899) and treated with Compound A using a serial dilution ranging from 0.1 nM to 1000 nM and including a DMSO control and incubated for 24 hrs at 5% CO2, 37°C. Cells were transferred from treatment plate to anti-CD3 coated plate (5 ug / mL anti-CD3 antibody, clone OKT3) and co-stimulated with anti- CD28 (1 ug / mL, clone CD28.2). Cells were incubated at 5% CO2, 37°C and cells and / or supernatants harvested at various timepoints following anti-CD3 / anti-CD28 co-stimulation for various readouts (24h, CD69; 48h, IL-2; 96h, proliferation). For CD69 surface evaluation, cells were washed with PBS and stained for 20 minutes at 4 C with anti-CD69 allophycocyanin (APC) antibody. Cells washed with PBS and evaluated by flow cytometry. APC fluorophore signal intensity (CD69) reported as Geometric Mean. IL-2 was evaluated within cellular supernatants using an IL-2 ELISA kit (Abcam, ab270883) according to manufacturer protocol. Optical density (O.D.) values (IL-2) were obtained at 450 nM. For proliferation assays, cells were labeled with cell trace violet (final dye concentration 12.5 uM). Cells were analyzed as a percentage of cell trace violet dye dilution (relative to unstimulated cells) by flow cytometry. For all assays, data were normalized to anti-CD3 / anti-CD28 co-stimulated DMSO control levels. The results of this study are shown in FIGS.3A-3C. Example 2.5: VAV1 degradation by a MGD in PBMCs after a single oral dose in mice Mice were treated orally with a single dose of Compound A at 10 mg / kg and blood samples were collected pre-dose and at 2, 6 and 24 hours post-dose. Compound formulation was prepared fresh the day of administration in 50% PEG400+50% (20% Captisol in water) by first dissolving PAT059980-WO-PCT Compound A in PEG400 followed by vortex and sonification, then adding 50% of 20% captisol in water with vortex until a clear solution or a uniform suspension was obtained. Plasma samples collected pre and post dosed were analyzed by Mass spectrometry to evaluate the compound concentration in ng / ml and blood samples were used to assess VAV1 protein levels and b-actin as loading control by western blotting (WB). Briefly, cells were rinsed with PBS and lysed using 30 µL RIPA lysis buffer (Pierce 89901), supplemented with EDTA and PhosStop (Roche 04906845001). Samples were run on 4- 15% precast gels (Bio-Rad 161-0732) at 10-15 µg / lane and transferred to pre-activated PVDF membranes (Millipore IPVH00010). Primary antibodies (mouse VAV1, CST 2502S and b-actin, CST 3700S) was diluted in blocking buffer (dil. 1 / 1000) and incubated with the membranes overnight at 4°C. After three washes with 1x TBST (5 minutes each), secondary antibodies (anti- rabbit IgG, CST 7074, dil.1 / 1000 and IRDyeⓇ 680RD Goat anti-Mouse IgG (H+L), Licor 926- 68070, dil.1 / 5000) were diluted in blocking buffer, added to membranes and incubated for 1 hour at room temperature. Signals were detected using an WB image systems. First the VAV1 protein levels were normalized to b-actin levels within the same samples than the ratio between the normalized VAV1 protein levels and the pre-dose levels were calculated and used for representation. The results of this study are shown in FIG.4. Example 2.6: Inhibition of disease progression in a MOG35-55-induced multiple sclerosis experimental autoimmune encephalomyelitis (EAE) mouse model To induce experimental autoimmune encephalomyelitis (EAE), C57BL / 6J mice were injected subcutaneously with an emulsified mixture consisting of 100 μg of the synthetic peptide derived from myelin oligodendrocyte glycoprotein (MOG35-55) and 200 µg M. tuberculosis mixed with incomplete Freund’s adjuvant. Mice were additionally injected intraperitoneally with 200 ng pertussis toxin at 0 and 48 hours post immunization. This immunization induces the activation and expansion of peripheral myelin-specific encephalitogenic T cells and their migration into the CNS. Once in the CNS, the activated T-cells initiate an inflammatory cascade, which ultimately leads to myelin destruction and symptoms of paralysis. From the day before disease induction (day -1), the mice were monitored daily and scored for clinical signs of EAE disease as follows: 0=no signs of disease; 1=limp tail or hind limb weakness; 2=limp tail and hind limb weakness; 3=partial hind limb paralysis; 4=complete hind limb paralysis; 5=moribund. Mice were then treated with vehicle (50 / 50 (v / v) PEG400 and 20% captisol in water) or once daily (QD) orally (PO) at 10 mg / kg with Compound A (resuspended in 50 / 50 (v / v) PEG400 and 20% captisol in water) or QD PO at 1 mg / kg with Dexamethasone from day 12 to day 18. A Compound A formulation was prepared PAT059980-WO-PCT fresh the day of administration by first dissolving Compound A in PEG400 followed by vortex and sonification, then adding 50% of 20% captisol in water with vortex until a clear solution or a uniform suspension was obtained. The results of this study are shown in FIG.5. Example 2.7: Oral dosing of Compound A inhibits EAE disease progression in a dose- dependent manner To induce experimental autoimmune encephalomyelitis (EAE), twelve C57BL / 6 (Beijing Vital River Laboratoriy Animal Co; #213) mice were injected subcutaneously with an emulsified mixture consisting of 100 μg of the synthetic peptide derived from myelin oligodendrocyte glycoprotein (MOG35-55; GL Biochem Ltd; #51716)) and 200 µg M. tuberculosis (Fifco; #231141)mixed with incomplete Freund’s adjuvant (Sigma-Alrich; #F5506). Mice were additionally injected intraperitoneally with 200 ng pertussis toxin (List Biological Laboratories; #180235AIA) at 0 and 48 hours post immunization. This immunization induces the activation and expansion of peripheral myelin-specific encephalitogenic T cells and their migration into the CNS. Once in the CNS, the activated T-cells initiate an inflammatory cascade, which ultimately leads to myelin destruction and symptoms of paralysis. From the day of disease induction (day -12), the mice were monitored every 3 days for clinical signs of EAE disease as follows: 0=no signs of disease; 1=limp tail or hind limb weakness; 2=limp tail and hind limb weakness; 3=partial hind limb paralysis; 4=complete hind limb paralysis; 5=moribund. On day 0, at disease onset, mice were treated with vehicle (10% captisol in water) Compound A at 1, 0.1, or 0.01 mg / kg with Compound A (resuspended in 10% captisol in water), or QD PO at 1 mg / kg with Dexamethasone (dissolved in saline; Shanghai SPH Sine Pharmaceutical Co; #H31020793) from day 12 to day 24 and monitored every 3 days for clinical signs of EAE disease as described above. A Compound A formulation was prepared fresh the day of administration by dissolving the Compound A in 10% captisol in water then vortexed until a clear solution or a uniform suspension was obtained. At peak of disease (day 6 post-treatment start), spinal cords of four mice per group were excised and VAV1 levels (normalized to β-actin and relative to vehicle-treated mice) were measured by western blot. To determine the levels of Vav1 in the spinal cord, tissues were excised after euthanasia and snap frozen. For sample preparation, frozen samples were defrosted, 30-100 mg of tissue was placed in a 2 mL microcentrifuge tube, and 400 μL RIPA buffer (Sigma; #R0278) containing 1% protease inhibitor cocktail (Roche; #04693124001) and 1% phosphatase inhibitor cocktail 2 (Sigma; #P5726) was added to each tube. Tissues were ground using a Tissuelyser (Shanghai Jingzin; #JXSTPRP-CL) at 50 hZ for 5 mins. Samples were then incubated on ice for 30 mins. PAT059980-WO-PCT After incubation, samples were centrifuged at 13, 523 x g for 10 mins at 4ºC, then transferred into new, pre-chilled microcentrifuge tubes. Protein concentrations was determined using a BCA assay kit (Thermo Fisher; #23225)) and samples were diluted to a final concentration of 2 μg / μL in RIPA buffer containing 4X LDS sample buffer (Invitrogen; #NP0007) and 10X sample reducing agent (Invitrogen; #NP0009). Once diluted, samples were boiled at 100ºC for 10 mins. Denatured samples were then stored at -80ºC. For western blotting, protein samples were defrosted and 15 μL of each sample was loaded in 4-12% Bis-Tris gels (Invitrogen; #WG1402BOX). Electrophoresis was then run in MES running buffer (Invitrogen; #NP0002) at 80 V for 30 mins then 120 V for 90 mins. Proteins were transferred to a nitrocellulose membrane with an iBlot 2 Gel Transfer Device (Invitrogen) using P3 for 7 mins. After transfer, membranes were washed (10 mL 1X TBST, 5 mins, 3 times), blocked (TBS Blocking Buffer (LI-COR;#927-60001), 1 h with agitation, room temperature), and washed again (1X TBST (Bio-Serve; #BS-P-15), 10 mins, 3 times). Vav1 and β-actin were detected by incubation with anti-Vav1 (CST; 2502) and β-actin (CST; #4967) antibodies (1:1000 or 1:2000 respectively in TBS Blocking Buffer containing 0.1% Tween-20 (Sigma; #P2287) at 4ºC overnight with gentle agitation). Membranes were then washed (10 mL 1X TBST, 10 mins, 3 times) and then incubated with secondary detection goat anti-mouse IgG-IRDye 860RD (LI-COR; #926-68070) and goat anti-rabbit IgG-IRDye 800CW (LI-COR; #926-32211) antibodies (both 1:10000 in TBD Blocking Buffer containing 0.1% Tween-20 for 1h at room temperature with gentle agitation, protected from light). Membranes were then washed (10 mL 1X TBST, 5 mins, 5 times) and protein levels were detected by fluorescence signal using an Odessey CLx Imaging System (LI-COR). Vav1 protein levels were quantified by fluorescence intensity relative to β-actin and normalized to the vehicle treatment group. The results of this study are shown in FIGS.6A and 6B. Example 2.8: Oral dosing of Compound A inhibits disease progression in a T cell transfer-induced model of colitis and reduces expression of calprotectin subunits (S100a8 / S100a9) within colon tissue in a T cell transfer-induced model of colitis To induce colitis, eight CD17-SCID mice were injected intraperitoneally with 0.5 x 106non-pathogenic activated CD45RBlow(no disease control group) or pathogenic naïve CD45RBhigh(treatment groups) CD4+ T cells isolated from Balb / c mice. To isolate T cells, spleens were collected, homogenized, and CD4+ T cells were enriched using negative magnetic selection (Stemcell; #19852) as per the manufacturer’s instructions. After enrichment, cells were stained with viability stain 780 (BD; #BD-565388), blocked with rat anti-CD16 / 32 (BD; #BD-553141), stained with rat anti-mouse CD4-APC (BD; #BD-553051) and rat anti-mouse CD45RB-PE (BD; PAT059980-WO-PCT #BD-553101), and then sorted based on CD45RB expression using fluorescence activated cell sorting (FACS). Transfer of naïve CD4+ T cells induced microbe peptide-specific immune responses in the colon leading to colitis-like inflammation. From the day of cell transfer (day 0), the mice were monitored daily for disease activity index (DAI) comprising weight loss and stool consistency assessment. On day 0, two hours post-cell transfer, mice were treated orally (PO) daily with vehicle (10% captisol in water) or Compound A at 10 or 1 mg / kg (resuspended in 10% captisol in water) for 42 days. A Compound A formulation was prepared fresh the day of administration by dissolving the Compound A in 10% captisol in water then vortexed until a clear solution or a uniform suspension was obtained. The results of this study are shown in FIG.7. To determine gene expression changes, at the end of the study colons from each group were excised and stored in RNAlater (Sigma; #R0901) at -80ºC. Samples were then defrosted, and RNA was extracted using an Rneasy Mini Kit (Qiagen; 74104) as per the manufacturer’s instructions. RNA samples were then assessed by NanoDrop (Thermo; #AZY1705823) and Qubit (Inviitrogen; #2322618036279). After RNA quality assessment, samples were assessed using the Nanostring Autoimmune Panel as per the manufacturer’s instruction. Breifly, ~100 ng RNA was processed in a hybridization reaction (65ºC for 20 hours) and loaded onto an nCounter Prep Station (NanoString Technologies; #1609D0496) for automated purification and RNA immobilization on an nCounter Master Kit cartridge (NanoString; #NAA-AKIT-012). Cartridges were then transferred to an nCounter Digital Analyzer (NanoString; #1804C0565) and assessed using the nCounter Mouse Autoimmune Profiling Panel (NanoString; #XT-CSO-MAIPI1-12). Quality control (QC) included image QC, binding density, positive control linearity, and positive control limit of detection. Background signal was calculated as twice the standard deviation above the mean of the negative control. The limit of detection was determined by detection of a 0.5 fM positive control probe. For normalization of gene counts, 8 of 20 standard housekeeping genes were assessed using common normalization methods including the mean, geomean, median of ratio. Counts in each sample were then normalized using these parameters. Differential expression of genes (DEG) was then determined on normalized gene counts to provide significant variance between Compound A and vehicle treated groups. The results of this study are shown in Table 2 below. Table 2: Differential gene expression after oral dosing of Compound A Gene Log2 fold change Adjusted p value S100a9 -3.403.67x10-9 S100a8 -3.248.56x10-7 PAT059980-WO-PCT Table 2 shows that expression of the calprotectin subunit genes (S100a9 / S100a8) were significantly decreased in Compound A treated mice compared to vehicle. At the end of the study, colons were excised, homogenized, and assessed for gene expression using the Nanostring Autoimmune Panel. Gene expression was normalized to house keeping genes and differential expression of genes was compared between Compound A and vehicle treated mice (table shows log2 fold change and adjusted p value of gene expression in Compound A compared to vehicle treated mice). Example 2.9: Oral dosing of Compound A Attenuates Disease Progression in a CIA mouse model To induce collagen-induced arthritis (CIA), fifteen DBA / 1 mice (Shanghai Vital River Laboratory Animal Technology Co; #218) were injected intravenously on days 0 and 21 with a mixture consisting of 100 μg of bovine collagen II (Sichuan University) dissolved in 100 mM acetic acid (Sigma; #A8976) emulsified in complete Freund’s adjuvant (CFA; Sigma; #F5881) 2- 3 cm from the base of the tail. This immunization induces the activation and expansion of collagen specific T- and B-cells that migrate into the paw joints. Once in the paw joints, the activated T- cells induce destruction of the joint and bone tissue, leading to redness and swelling of the phalanges, and B-cells produce antibodies against collagen II. Following the second immunization, mice were monitored daily for clinical signs of disease as follows: 0=erythema and redness; 1=Erythema or mild redness near ear the tarsal, ankle, or metatarsal or one toe with erythema and redness; 2=Ankles and metatarsals are slightly erythematous and swollen with two or more toes with erythema and redness; 3=Moderate erythema and swelling of the ankle, wrists, and metatarsals; 4=Ankles, wrists, metatarsals, and toes are severely red and swollen. Upon disease onset, mice were randomly enrolled into treatment groups: vehicle (10% captisol in water; PO, QD) or Compound A (1 mg / kg, PO, QD) and treated for 21 days. Compound A formulation was prepared fresh the day of administration by dissolving the Compound A in 10% captisol in water then vortexed until a clear solution or a uniform suspension was obtained. At the end of the study, serum was collected from each mouse and assessed by ELISA for levels of anti-collagen II IgG1 antibodies. ELISA plates containing 100 μL / well of 40 μg / mL bovine collagen II in acetic acid were incubated overnight at 4ºC. The solution was then aspirated and washed 3 times with 400 μL Wash Buffer (0.001% Tween-20 in PBS) with 1 min soaking between each wash step. Wells were then blocked using 1% BSA in 1X PBS for 2 hours at room temperature. Wells were then washed as previously. A 2-fold serial dilution of IgG1 standard (starting at 2000 units / m) or prediluted serum (1:5000) were then added to individual wells and incubated for 2 hours at room temperature. PAT059980-WO-PCT Wells were then washed 4 times as described above. To detect antibody binding, 100 μL of secondary antibody (goat anti-mouse IgG1-HRP; Invitrogen; #PA1-74424) was added to wash well and incubated at room temperature for 1 hour. After incubation, 100 μL of TMB substrate (Abcam; #ab171523) was added to each well, incubated for 5-30 mins, then quenched by addition of 100 μL Stop Solution (Abcam; #ab171529). Plates were then read at 450 nm with 570 nm values substracted from those of 450 nm and analyzed. Using standards, concentrations of each group were calculated at units / mL. The results of this study are shown in FIGS.8A-8B. Example 2.10: Compound A Attenuates BCR-Mediated Activity in Primary Human B-cells Peripheral blood mononuclear cells (PBMC) were first isolated from human blood leukopaks. Each leukopak was diluted by adding 40 mL of the leukopak contents into 60mL of 1x PBS into a disposable Nalgene 150 mL bottle. The diluted blood mixture was transferred evenly among three Accupsin tubes (~30mL / tube). The mixture in Accuspin tubes was centrifuged at 720 x g for 20 minutes without brake at room temperature. Peripheral blood mononuclear cells) (PBMC) were collected from the interphase with a sterile transfer pipette and transferred into new 50 mL tubes. PBMCs were washed with 1X PBS and counted using Nexcelom cell counter. From the isolated PBMCs, B cells were isolated using EasySep B cell isolation kit (Stemcell; #17954) following the manufacturer’s manual magnetic isolation technique. Cells were treated with Compound A at the indicated final concentrations or DMSO control and incubated at 37°C in a humidified incubator with 5% CO2. After treatment, B cells were cultured in RPMI 1640 (Gibco; #22400089) supplemented with 10% fetal bovine serum (Gibco; #A31605-01; Lot#2408990P), 2mM L-glutamine (Gibco; #35050061), 100 IU / mL penicillin / streptomycin (Gibco; #15140122), 1 mM sodium pyruvate (Gibco, #11360070), 0.01 M HEPES (Gibco, #15630080), 1% non- essential amino acids (Gibco; #11140050), and 55 μM β-mercaptoethanol (Gibco; #21985023), and stimulated with assay-dependent stimuli. For CD69 expression and IL-6 secretion, B cells were stimulated with anti-IgM (1 μg / mL; Southern Biotech; #2022-14) and recombinant human IL-4 (10 ng / mL; R&D Systems; #305-IL-010) for 24 hrs. For IgG secretion, B cells were stimulated with anti-IgM (1 μg / mL), BAFF (30 ng / mL; R&D Systems; #7537-BF-025), IL-21 (100 ng / mL; PeproTech; #200-2), and soluble CD40L (50 ng / mL; R&D Systems; #6245-C) for 5 days. For CD69 expression, cells were blocked with TruStain FcX (BioLegend; #422302), stained with mouse anti-human CD19-BV421 (BD; #562440; Clone HIB19) and anti-human CD69-APC (BioLegend; 310910; Clone FN50) then, then assessed by flow cytometry. For IL-6 and IgG, supernatants were assessed by Alphalisa as per the manufacturer’s instructions. Mean fluorescence PAT059980-WO-PCT intensity (MFI) of CD69-APC was calculated on the CD19+ population using FlowJo (BD). MFI of CD69 for Compound A treated samples was normalized to DMSO stimulated and unstimulated control. Normalized data were transferred to Prism 9.3.1 (GraphPad) and fitted with a four- parameter model ([Inhibitor] vs. response -- Variable slope). The results of this study are shown in FIGS.10A-10C. EXAMPLE 3: TABLETS Example 3.1: Identification of polymers for solid dispersions of Compound A To evaluate which polymers would be most suitable for a solid dispersion of Compound A, the amorphous solubility of Compound A in different polymers in a biorelevant medium was assessed. The biorelevant medium used was Fasted State Simulated Intestinal Fluid (FaSSIF), which had a composition as shown in Table 3. If a substance is soluble in this medium, this suggests that the substance will also be soluble in the upper intestine of a subject when the subject is in the fasted state. Table 3: Composition of FaSSIF medium Component Concentration Sodium Taurocholate 3.0 mM Lecithin 0.75 mM Sodium Chloride 106 mM Monobasic Sodium Phosphate 28.4 mM Sodium Hydroxide 8.7 mM The following polymers were tested: • HPMCAS LG • HPMCAS MG • HPMCAS HG • HPMC E3 • PVPVA 64 • Eudragit L100 Amorphous solubilities (based on the onset of liquid-liquid phase separation (LLPS)) were determined at 37 °C and pH ~6.5 in FaSSIF medium with 300 µg / mL pre-dissolved polymer using the solvent-shift UV assay described in“Assessment of the Solubility of a Group of Diverse Drugs PAT059980-WO-PCT Using New Experimental and Theoretical Approaches”, Luis Almeida e Sousa, Susan M. Reutzel- Edens, Gregory A. Stephenson, and Lynne S. Taylor, Mol. Pharmaceutics. A concentrated stock solution of Compound A in DMSO was delivered into the FaSSIF medium to reach a concentration of ~120µg / mL and the solution was monitored for precipitation for five hours. Results are shown in FIG. 14. There was visual precipitation in the control and Eudragit L100 samples within 5 minutes of addition of the Compound A stock solution. There was visual precipitation in the PVPVA 64 sample within 25 minutes of addition of the Compound A stock solution. All samples except the HPMCAS HG sample had visible precipitation the following day. Based on these results, HPMCAS HG and HPMCAS MG are preferred polymers for a solid dispersion of Compound A due to their ability to sustain supersaturation of Compound A for up to 5 hours. Example 3.2: Solid dispersions comprising Compound A Four spray dried dispersions (SDDs) comprising Compound A were prepared. Their compositions are indicated in Table 4 below. Table 4: Compositions of SDDs comprising Compound A SDD Composition SDD 1 [1:3] Compound A: HPMCAS HG SDD 2 [2:3] Compound A: HPMCAS HG SDD 3 [1:3] Compound A: HPMCAS MG SDD 4 [2:3] Compound A: HPMCAS MG Preparation of spray dried dispersions 1-4 SDD spray solutions were prepared at a 5.0 wt% solids loading in 80:20 DCM:MeOH. The polymer was dissolved in the solvent system followed by addition of Compound A. The solutions were sprayed using a ProCepT 4M8-Trix pharmaceutical spray dryer with the parameters as shown in Table 5 below. The wet SDDs were oven dried in a vacuum oven at ~10 inHg and 40⁰C for ~24 hours.

All SDDs had acceptable chemical and physical characteristics of an amorphous material.

FaSSGF (Fasted State Simulated Gastric Fluid) is another biorelevant media. The FaSSGF media was at pH ~ 1.3 and had the composition shown in Table 7. If a substance is soluble in FaSSGF, this suggests that the substance will also be soluble in the stomach of a subject when the subject is in the fasted state. Table 7: Composition of FaSSIF medium Component Concentration Sodium Taurocholate 0.08 mM Lecithin 0.02 mM Sodium Chloride 34.2 mM Hydrochloric Acid 25.1 mM The target concentration of Compound A was ~200µg / mL for the FaSSGF medium, and ~100µg / mL for the FaSSIF medium. The results are shown in FIG.15. All SDDs sustained supersaturated concentrations over the 5.5 hour dissolution period and were ~7-9 times more soluble than crystalline Compound A. The SDDs with Compound A:polymer at a ratio of [1:3] achieved higher overall concentrations compared SDDS with Compound A:polymer at a ratio of [2:3]. SDDs with HPMCAS HG were able to sustain slightly higher concentrations compared to SDDs with HPMCAS MG. Thus, SDDs with Compound A and polymer at a ratio of [1:3], and SDDs with HPMCAS HG, are preferred. Stability testing SDDs 1-4 were stored for 2 weeks at 40°C and 75% relative humidity (RH) in a closed dish with no desiccant. SDDs 1-4 were chemically stable after this time, and the amorphous nature of the SDDs was maintained. SDDs 1, 2, and 4 were also physically stable. DSC data for SDD3 indicates that there is a secondary Tg at ~116°C, which is likely due to phase separation. This may have been caused by water uptake – Karl Fischer titration showed that SDD3 had the highest level of water content of SDDs 1-4, which is likely due to higher hygroscopicity of HPMCAS M compared to HPMCAS H. SDD3 therefore requires storage in a closed dish with a desiccant. Example 3.3: SDD1 Scale-Up Batch 1 PAT059980-WO-PCT ~500g of [1:3] Compound A:HPMCAS HG was produced on a ProCepT 4M8-Trix pharmaceutical spray dryer. Due to the large batch size, the batch was split into three sublots and produced over 3 days. The spray solution preparation and spray drying parameters matched those described above for SDD1, and are also described below. HPMCAS HG was obtained from Shin- Etsu, and dichloromethane (World / GMP grade) and methanol (World / GMP grade) was obtained from EMD Millipore. Spray solution preparation All spray solutions were prepared one day before the spray. Compound A was added to the solvent solution first and the solution was mixed for at least 1 hour. Then, the polymer was added and the solution was mixed overnight. Table 8 summarizes the spray solution composition.

Secondary drying parameters are summarized in Table 10. Table 10: Secondary drying parameters for scale-up batch of SDD1 Parameter Value Temperature (°C) 40 Vacuum Setting (inHg) -5 N2Purge (CFH) 15 All sublots were removed from the oven after 45 hours of secondary drying. A small aliquot was collected from each bottle for PXRD analysis. Once the amorphous nature of each Sublot was confirmed, the material was combined by transferring all sublots into an LDPE bag and mixing by hand. The overall yield of the dry SDD was 74.9%. Characterization Results from physical and chemical characterization of the scale-up batch of SDD1 are summarized in Table 11. These properties were found to be acceptable.

Due to differences in the atomization mechanism between the Procept and Mobile Minor, PAT059980-WO-PCT the materials produced generally have different particle size differences. The Procept utilizes a two fluid nozzle to atomize the spray solution whereas the Mobile Minor utilises a pressure nozzle. A two fluid nozzle generally produces finer droplets during spray drying, which results in smaller particles being produced for Procept sprays than for Mobile Minor sprays. SEM images showed that the Procept SDD had overall smaller particles compared to MM SDD, with largest particles sizes being ~60µm for the Procept material and 110µm for the MM SDD. Example 3.5: 0.5 mg tablet formulations Four tablet formulations were prepared with various fillers, including plastic fillers (ProSolv HD90 or Avicel PH 101) and a brittle filler (Pearlitol 100).

The sample mass and bulk density were recorded. The graduated cylinder was then placed on an Autotap and tapped for 500 and 1000 taps to measure the tapped density. The bulk and tapped densities were used to calculate the Carr Index and Hausner Ratio using the equations below, and these values were used to designate the blend’s flowability in accordance with Table 21.

All formulations exhibited acceptable flow properties. The formulation 6 granules showed similar flow properties to the formulation 6 IG blend, likely due to formation of fines during the manual granulation process. This phenomenon is expected to improve when producing granules during roller compaction via Gerteis as ribbons are less prone to forming fines during the milling process compared to slugs.

Compression profiles of tabletability (FIG. 16) and compactability (FIG.17) were generated. Tabletability is a measure of how strong a tablet can be made at various compression stresses. Compactibility describes whether a tablet is able to achieve the desired tensile strength at the target solid fraction. The tablets were also tested for weight, thickness, and hardness. Formulations 5 and 6 exceeded the 2-3 MPa tensile strength and 0.7-0.8 solid fraction targets even at low compression pressures, and therefore have acceptable tabletability and compactibility properties for a direct compression process. It is important that the formulation 7 IG blend has acceptable compression properties so that the granules produced by the dry granulation process can be compressed a second time in the final tablet production. For roller compacted blends, achieving a maximum tensile strength between 3.0-4.0 Mpa below a compression stress of 300 Mpa is an ideal target. This allows for the blend to undergo multiple rounds of compression and maintain acceptable tensile strengths. The formulation 6 IG blend was able to exceed the 3-4 MPa tensile strength and 0.7-0.8 solid fraction targets even at low compression pressures, and therefore has acceptable compressibility, tabletability, and compactibility properties. Additionally, the formulation 7 EG blend was able to exceed the 2-3 MPa tensile strength and 0.7-0.8 solid fraction targets even at low compression pressures, and therefore has acceptable compressibility, tabletability, and compactibility properties. The 0.5mg and 2mg blends achieved the highest tensile strengths likely due to the higher concentration of filler present in those blends. Disintegration of tablets of formulations 5-7 Disintegration testing was performed on high tensile strength tablets (3.0 MPa) of formulations 5-7. Procedure 1. Setup DisiTest50 Automated Disintegration Tester per standard operating procedure SOP- 0146 with purified water and allow it to heat up to 37.0ºC ± 0.5ºC. 2. Perform disintegration testing, recording the time when the tablets are fully disintegrated. Full disintegration time is when the tablet core has dispersed, leaving only free floating powder. PAT059980-WO-PCT Results Table 23: Disintegration times for tablets with formulations 5-7 Tablet Disintegration Time min:sec 00:06 Formulation 5 ~3MPa Tensile Strength 00:06 00:08 00:06 Formulation 6 ~3MPa Tensile Strength 00:06 00:08 00:10 Formulation 7 EG ~3MPa Tensile Strength 00:12 00:12 All tablets across all three formulations showed rapid disintegration in water. Summary Overall, all formulated blends showed good tabletability and achieved acceptable tensile strengths within 250-300 MPa compression stress. Formulations 5 and 6 provided acceptable blend uniformity, flowability, compression profiles, and disintegrations times, and are therefore suitable for manufacturing direct compression immediate release tablets. In particular, tabletability of formulations 5 and 6 is considered excellent, with tablets at the desired tensile strength of 1.7-2.0 MPa expected to be produced at low compression stress (<100MPa). The formulation 7 intra-granular blend had acceptable blend uniformity, flowability, and roller compaction properties, and therefore is suitable for granulation. In particular, the intra- granular blend has good compactibility properties and is expected to produce strong granules, which can withstand downstream processing. The formulation 7 extra-granular blend also exhibited acceptable flowability, compression profile, and disintegration time. Formulation 7 is therefore acceptable for dry granulation and immediate release tablet manufacturing. Formulation 8 gave acceptable blend uniformity results for the 0.1 mg strength and demonstrated good chemical stability at 40 °C for 2 weeks. Direct blending was successful thus offering the advantage of a streamlined process. Direct compression could also be applied in this case and coating process was uneventful. Overall, formulation 8 is considered acceptable for a dry granulation and immediate release tablet manufacturing.

The other softgel fills described above can be prepared analogously. The sample preparation bottle was kept covered with parafilm to avoid any air getting into the formulation. 1. Weigh Compound A into a 60mL amber glass bottle. Add benzyl alcohol and homogenize using homogenizer with large blade at low speed (2 to 3) for 30 minutes. Observe whether all of Compound A is in solution. If not, mix for additional 15 minute increments until Compound A is in solution or until 1.5 hours have elapsed. 2. If Compound A dissolves in the benzyl alcohol, then once there is a clear solution, add 25 g of Kolliphor EL before homogenizing and mixing at slow speed (2-3) for 20 minutes. If Compound A does not dissolve in the benzyl alcohol after 1.5 hours of mixing, add 35 g of Kolliphor EL, then homogenize and mix at slow speed (2-3) for 40 minutes. Check for solubility of Compound A every 10 minutes. 3. Record Tare weight of empty 250mL amber glass bottle with cap. 4. Carefully transfer all material into the 250 mL amber glass bottle. Rinse the 60mL bottle with the remaining Kolliphor EL and transfer to 250 mL glass bottle. 5. Add 30 g Maisine CC to the 60 mL bottle, rinse by mixing slowly and transfer to 250 mL glass bottle. Add the remaining Maisine CC to 60 mL bottle, rinse by mixing slowly and transfer to 250 mL glass bottle. Add the lecithin to the 250 mL bottle. Then add the BHT and BHA. Add one drop of Simethicone to facilitate deaeration. 6. Homogenize and mix using homogenizer with large blade at low speed (2 to 3) for 30 to 45 minutes to obtain a clear, light yellow, slightly translucent solution. 7. De-aerate using vacuum. Example 4.3: Solubility of softgel fill formulations S2, S3, S5, and S6 The kinetic solubility of formulations S2, S3, S5, and S6 in biorelevant media was evaluated in vitro using a two-step dissolution test. This test involves measuring dissolution of the API in simulated gastric fluid (FaSSGF) which is subsequently converted into simulated intestinal fluid (FaSSIF). See Examples 3.1 and 3.2 for details of these media. This simulates the in vivo PAT059980-WO-PCT process after oral administration. The test was carried out on a Pion instrument with a USP II apparatus, in which API concentration was determined by fiber optic probes. The following parameters were used: final volume = 500 mL; temperature: 37⁰C; paddle: 75 RPM. 2-piece hardshell capsules containing approximately 2g of formulation were utilized for the test. Results are shown in FIG. 18. Due to the low concentration of Compound A in the formulation, there was a lot of background noise from the excipients. This meant that the data for the formulations in FaSSGF and the data for S5 could not be analysed. Example 4.4: Physical stability of softgel fill formulations Softgel fill formulation S7 Samples of softgel fill formulation S7 were spiked with water, glycerin, gel, or plasticizer (Sorbitol Special) and stored for 8 weeks at ambient conditions or at 40°C and 75% relative humidity. After 2 weeks each solution remained a clear, light yellow, translucent solution. After 4 weeks phase separation was observed in each sample. Table 26: Composition of spiked samples of softgel fill formulation S7 Sample composition 4.0g S7 spiked with 5% water 3.0g S7 spiked with 1.0g glycerin, USP 3.0g S7 spiked with 1.0g Sorbitol Special, NF 3.0g S7 spiked with 1.5g gelatin strip 4.0g S7 Softgel fill formulations S9-S11 Samples of softgel fill formulations S9-S11 were stored at 5°C and 40°C. No precipitation was observed in any of the samples at after 3 weeks. Example 4.5: Chemical stability of softgel fill formulations Certain softgel fill formulations described in example 4.1 were stored under various conditions and then analysed by HPLC. Results are shown in Table 29. The major impurity detected (with a relative retention time 0.96) was present in the API itself at 1.2%. Another impurity (with a relative retention time of 1.32) is due to free radical based oxidative degradation of Compound A. However, use of ascorbyl palmitate in fill formulation S15 avoids this.

The simethicone was added to the Becomix 2.5L. The Compound A wetted with small portion of benzyl alcohol was transferred to the Becomix 2.5L and mixed for 60 minutes at 35 °C with the homogenizer speed 7.5m / s and the agitator speed 1.0m / s. Compound A dissolved in the fill material. All the remaining excipients were added to Becomix 2.5L and mixed for additional 30 minutes under same conditions. It was visually confirmed that there were no particles present. The material was deaerated under vacuum. Preparation of softgels The fill material was encapsulated to produce the softgels using a 7th generation encapsulation machine with die (16 oblong) in pilot plan. The gel formula for the softgels consisted of gelatin, sorbitol glycerin blend, titanium dioxide, and purified water. A moisture ingress study was performed to evaluate water migration from wet shell to fill material during encapsulation and it was determined that water migration was not significant. Therefore, in-process fill weight adjustment was not necessary. The softgels were dried after encapsulation in a drying tunnel. After drying the softgels were manually washed and then packaged in aluminium bags and sealed. The softgels were perfect in shape, with a good seam and no physical deformity. Testing of softgels PAT059980-WO-PCT The softgels were stored for 1 month at 25 °C and 60% relative humidity, and at 40 °C and 75% relative humidity, and analysed for stability, hardness, water content, and rupture. Results are shown in the tables below. The softgels did not leak under either storage condition. Table 31: Stability testing of softgel formulations.

For the encapsulation of the soft gelatin capsules, an opaque white gel mass is used. The clear gel mass is prepared by using gelatin, Sorbitol Special – Glycerin Blend as plasticizer, and purified water. The gel mass is then color-converted to an opaque white color by adding TiO2 and purified water to the gel mass. After drying is completed, the capsules are visually inspected for any physical defects and washed. The washed softgel capsules are counted and bulk-packaged in carton with polybag. The 0.1 and 0.5 mg softgel capsules are bottled, closed with a capper, and induction sealed.

However, assay indicates that Compound A was almost completely dissolved since measured value agrees well with theoretical (0.55 mg / mL). Example 5.2: Larger scale batch of oral solution L20 The first batch of L20 was exposed to daylight for 4-5 hours during preparation and could have reached a temperature of 30-35° C due to heat from the magnetic stirrer device. A second, larger scale batch of L20 was prepared under a more controlled environment with limited heat and light exposure and shorter mixing times. This batch had a total volume of 100mL and consisted of a solution of 0.5 mg / mL Compound A in 200 mg / mL 2-hydroxypropyl-β-cyclodextrin in water.

The water was added to a container and stirred at about 300 rpm using a 30 mm magnetic stir bar. 2. The cyclodextrin was added and allowed to dissolve (this is usually complete in less than 15 minutes). 3. Compound A was added and allowed to dissolve (this usually takes around 1.5 hours), resulting in a clear solution that was almost completely free from visible particles. Stability and pH data The new batch of L20 was then stored refrigerated and analysed. Results of the analysis are shown in Table 42. Assay data indicated complete dissolution of Compound A in the vehicle (99.8% recovery) and improved stability. The pH of the formulation was close to 7 (about 7.3), which is acceptable for an oral solution.

One form was a 0.5 mg softgel capsule filled with fill formulation S20 as described in Example 4.1. Softgel capsules of 0.1 mg (filled with fill formulation S19 as described in Example 4.1) and 1.0 mg strengths (filled with fill formulation S5 as described in Example 4.1) were also investigated. Tablets of two different strengths (0.5 and 10 mg; approximate average of 0.2 and 3.2 mg / kg, respectively) were PAT059980-WO-PCT also used. The 0.5mg tablet was prepared from tablet formulation 5 as described in Example 3.5, and the 10mg tablet was prepared from tablet formulation 7 as described in Example 3.7. In addition, a study was run to evaluate the pharmacokinetic and pharmacodynamic properties of single IV and PO doses of Compound A in adult female and male cynomolgus monkeys. The exposure of Compound A up to 300 mg / kg in adult male and female cynomolgus monkeys was also evaluated. This study used Compound A formulated in liquid composition L33. Dosing Administration of Compound A to adult female and male Cynomolgus monkeys (n =2) or adult male (n =3) was performed at WuXi AppTec (Shanghai) Co., Ltd., or Pharmaron (Ningbo). The monkeys weighed 2.1-4.15 kg at dosing. The liquid formulation (L33) was also tested at 0.2 mg / kg, 5.0 mg / kg, 10 mg / kg, 30 mg / kg, and 100 mg / kg (data not shown).

Plasma proteins were precipitated using acetonitrile containing the internal PAT059980-WO-PCT standard (ISTD) verapamil or dexamethasone. Twenty (20) μL or three (3) μL of the analyte mixture was injected for LC-MS / MS analysis. The calibration curves were constructed by plotting the peak-area of analyzed peaks against known concentrations. The lower limits of quantitation were 0.05, 0.2 or 1 ng / mL plasma. The data were subjected to linear regression analysis with 1 / x2weighting. Analysis was performed on an LC-MS / MS system comprised of a Sciex API4000, API5500 or API6500 tandem mass spectrometer (AB Sciex, Foster City, CA) interfaced to an ACQUITY UPLC system (Waters, Milford, MA) or Shimadzu. Analyses were performed using an ACQUITY UPLC BEH C18 (1.7 μm 2.1 × 50 mm) or Shim-pack Velox Biphenyl (1.8 μm 2.1*50mm) for chromatographic separations at a column temperature of 50°C. Mass spectrometric detection of the analyte was accomplished using the ESI+ ionization mode. The transitions of the protonated precursor ions to the selected product ions were as follows: Compound A (393.2 → 320.1 amu) or (393.05 → 320.20 amu), and the ISTD, verapamil (455.2 → 164.9 amu) or dexamethasone (393.14→373.10 amu). Data Analysis The pharmacokinetic parameters of Compound A were calculated by a non-compartmental analysis using WinNonlin Version 6.3 (Pharsight, Mountain View, CA). Maximum plasma concentrations (Cmax) and their time of occurrence (Tmax) were both obtained directly from the measured data. Microsoft Office Excel 2012 (Redmond, WA) was used for calculation of mean and standard deviation. Results Average PK parameters of Compound A are presented inTable 45 and Table 46 below and graphically in FIG 19. A pharmacodynamic (PD) measure is graphically shown in FIG 20. Plasma concentration curves for individual monkeys dosed with tablets and capsules are shown in FIGS. 21A-E. Compound A exposure data for the capsule and tablet formulations based on AUC(0- last) / Dose was compared with the oral dose solution and / or suspensions up to 5 mg / kg. Exposures using either the Compound A capsule or tablet form was similar to that using the oral solutions / suspensions. After a bolus push of an IV dose at 0.5 mg / kg in fasted monkeys, Compound A showed a plasma clearance of 1.2 mL / min / kg. The corresponding value for the estimated apparent volume of distribution at steady-state (Vdss) was approximately 0.7 L / kg, which is slightly larger than that PAT059980-WO-PCT of total body water. The average AUC0-last value was 6407 ng•hr / mL. The plasma clearance and apparent volume of distribution values resulted in a plasma elimination half-life of 8.2 hr (Table 45). Compound A, dosed PO at 1 mg / kg in a fasted state, was rapidly absorbed resulting in an average maximum plasma concentration (Cmax) of 799 ng / mL at an apparent Tmax of 3.0 hr. The average systemic exposure (AUC0-last) was 7386 ng•hr / mL which gave rise to an absolute oral bioavailability value of 58% (Table 46). When investigating the dose linearity of Compound A in free form dosed orally from 0.02 to 300 mg / kg, Compound A was found to be variable across the dose range and less than proportional. In addition, there does not appear to be any differences in exposure of Compound A between the two sexes (data not shown). VAV1 degradation was also measured after a 1 mg / kg Compound A PO dose (FIG.20). Compound A reduced VAV1 protein levels by 6 hrs post dose and those levels were maintained to 24 hrs.

Compound A exhibited an average Clp value about 1 / 20th that of hepatic blood flow (1.2 mL / min / kg), an average AUC0-last value of 6407 ng•hr / mL and an average Vdss value of 0.7 L / kg, yielding an average plasma elimination t1 / 2 of 8.2 hr following a single IV dose of 0.5 mg / kg. Compound A, dosed PO, once, at 0.02 to 30 mg / kg, showed an increase in exposure and was saturating at doses above 100 mg / kg. The subsequently average absolute oral bioavailability across doses ranged from 3-100%.
