[0050] As used herein, the term "antibody" is used in the broadest sense and covers fully assembled antibodies, antibody fragments that can bind antigen (e.g., Fab, F(ab')₂, Fv, single chain antibodies, diabodies, antibody chimeras, hybrid antibodies, bispecific antibodies, humanized antibodies, and the like), and recombinant peptides comprising the forgoing.

[0051] The terms "monoclonal antibody" and "mAb" as used herein refer to an antibody obtained from a substantially homogeneous population of antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally occurring mutations that may be present in minor amounts.

[0052] In some instances, antibodies are heterotetrameric glycoproteins of about 150,000 daltons, composed of two identical light (L) chains and two identical heavy (H) chains. Each light chain is linked to a heavy chain by one covalent disulfide bond, while the number of disulfide linkages varies among the heavy chains of different immunoglobulin isotypes. Each heavy and light chain also has regularly spaced intrachain disulfide bridges. Each heavy chain has at one end a variable domain (VH) followed by a number of constant domains. Each light chain has a variable domain at one end (VL) and a constant domain at its other end; the constant domain of the light chain is aligned with the first constant domain of the heavy chain, and the light chain variable domain is aligned with the variable domain of the heavy chain. Particular amino acid residues are believed to form an interface between the light and heavy-chain variable domains.

[0053] The term "variable" refers to the fact that certain portions of the variable domains differ extensively in sequence among antibodies. Variable regions confer antigen-binding specificity. However, the variability is not evenly distributed throughout the variable domains of antibodies. It is concentrated in three segments called complementarity determining regions (CDRs) or hypervariable regions, both in the light chain and the heavy-chain variable domains. The more highly conserved portions of variable domains are celled in the framework (FR) regions. The variable domains of native heavy and light chains each comprise four FR regions, largely adopting a β-pleated-sheet configuration, connected by three CDRs, which form loops connecting, and in some cases forming part of, the β-pleated-sheet structure. The CDRs in each chain are held together in close proximity by the FR regions and, with the CDRs from the other chain, contribute to the formation of the antigen-binding site of antibodies (see, Kabat et al. (1991) NIH PubL. No. 91-3242, Vol. I, pages 647-669). The constant domains are not involved directly in binding an antibody to an antigen, but exhibit various effector functions, such as Fc receptor (FcR) binding, participation of the antibody in antibody-dependent cellular toxicity, initiation of complement dependent cytotoxicity, and mast cell degranulation.

[0054] The term "hypervariable region," when used herein, refers to the amino acid residues of an antibody that are responsible for antigen-binding. The hypervariable region comprises amino acid residues from a "complementarily determining region" or "CDR" (i.e., residues 24-34 (LI), 50-56 (L2), and 89-97 (L3) in the light-chain variable domain and 31-35 (HI), 50-65 (H2), and 95-102 (H3) in the heavy-chain variable domain; Kabat et al. (1991) Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institute of Health, Bethesda, Md.) and/or those residues from a "hypervariable loop" (i.e., residues 26-32 (LI), 50-52 (L2), and 91 -96 (L3) in the light-chain variable domain and (HI), 53-55 (H2), and 96-101 (13) in the heavy chain variable domain; Clothia and Lesk, (1987) J. Mol. Biol., 196:901 -917).

"Framework" or "FR" residues are those variable domain residues other than the hypervariable region residues, as herein deemed.

[0055] "Antibody fragments" comprise a portion of an intact antibody, preferably the antigen- binding or variable region of the intact antibody. Examples of antibody fragments include Fab, Fab, F(ab')2, and Fv fragments; diabodies; linear antibodies (Zapata et al. (1995) Protein Eng. 10: 1057-1062); single-chain antibody molecules; and multispecific antibodies formed from antibody fragments. Papain digestion of antibodies produces two identical antigen-binding fragments, called "Fab" fragments, each with a single antigen-binding site, and a residual "Fc" fragment, whose name reflects its ability to crystallize readily. Pepsin treatment yields an F(ab')2 fragment that has two antigen-combining sites and is still capable of cross-linking antigen. [0056] "Fv" is the minimum antibody fragment that contains a complete antigen recognition and binding site. This region consists of a dimer of one heavy- and one light-chain variable domain in tight, non-covalent association. It is in this configuration that the three CDRs of each variable domain interact to define an antigen-binding site on the surface of the V_H-V_L dimer. Collectively, the six CDRs confer antigen-binding specificity to the antibody. However, even a single variable domain (or half of an Fv comprising only three CDRs specific for an antigen) has the ability to recognize and bind antigen, although at a lower affinity than the entire binding site.

[0057] The Fab fragment also contains the constant domain of the light chain and the first constant domain (C_HI) of the heavy chain. Fab fragments differ from Fab' fragments by the addition of a few residues at the carboxy terminus of the heavy chain C_HI domain including one or more cysteines from the antibody hinge region. Fab'-SH is the designation herein for Fab' in which the cysteine residue(s) of the constant domains bear a free thiol group. Fab' fragments are produced by reducing the F(ab')2 fragment's heavy chain disulfide bridge. Other chemical couplings of antibody fragments are also known.

[0058] The "light chains" of antibodies (immunoglobulins) from any vertebrate species can be assigned to one of two clearly distinct types, called kappa (κ) and lambda (λ), based on the amino acid sequences of their constant domains.

[0059] Depending on the amino acid sequence of the constant domain of their heavy chains, immunoglobulins can be assigned to different classes. There are five major classes of human immunoglobulins: IgA, IgD, IgE, IgG, and IgM, and several of these may be further divided into subclasses (isotypes), e.g., IgGl, IgG2, IgG3, IgG4, IgAl, and IgA2. The heavy-chain constant domains that correspond to the different classes of immunoglobulins are called alpha, delta, epsilon, gamma, and mu, respectively. The subunit structures and three-dimensional

configurations of different classes of immunoglobulins are well known. Different isotypes have different effector functions. For example, human IgGl and IgG3 isotypes have ADCC (antibody dependent cell-mediated cytotoxicity) activity.

[0091] In some embodiments, the compositions disclosed herein are administered for prophylactic, therapeutic, or maintenance treatment. In some embodiments, the compositions disclosed herein are administered for therapeutic applications. In some embodiments, the compositions disclosed herein are administered for therapeutic applications. In some

embodiments, the compositions disclosed herein are administered as a maintenance therapy, for example for a patient in remission.

[0092] In the case wherein the patient's status does improve, upon the doctor's discretion the administration of the compounds may be given continuously; alternatively, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a "drug holiday"). The length of the drug holiday can vary 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, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday may be from 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%, or 100%.

[0093] Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, can be reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. Patients can, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.

[0094] The amount of a given agent that will correspond to such an amount will vary depending upon factors such as the particular compound, the severity of the disease, the identity (e.g., weight) of the subject or host in need of treatment, but can nevertheless be routinely determined in a manner known in the art according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, and the subject or host being treated. In general, however, doses employed for adult human treatment will typically be in the range of 0.02-5000 mg per day, or from about 1-1500 mg per day. The desired dose may conveniently be presented in a single dose or as 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.

[0095] The pharmaceutical composition described herein may be in unit dosage forms suitable for single administration of precise dosages. In unit dosage form, the formulation is divided into unit doses containing appropriate quantities of one or more compound. The unit dosage may be in the form of a package containing discrete quantities of the formulation. Non-limiting examples are packaged tablets or capsules, and powders in vials or ampoules. Aqueous suspension compositions can be packaged in single-dose non-reclosable containers. Alternatively, multiple- dose reclosable containers can be used, in which case it is typical to include a preservative in the composition. By way of example only, formulations for parenteral injection may be presented in unit dosage form, which include, but are not limited to ampoules, or in multi-dose containers, with an added preservative. [0096] The foregoing ranges are merely suggestive, as the number of variables in regard to an individual treatment regime is large, and considerable excursions from these recommended values are not uncommon. Such dosages may be altered depending on a number of variables, not limited to the activity of the compound 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.

[0097] Toxicity and therapeutic efficacy of such therapeutic regimens can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between LD50 and ED50. Compounds exhibiting high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a range of dosage for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with minimal toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized.

Pharmaceutical Compositions/Formulations

[00222] Disclosed herein, in certain embodiments, are compositions for treating a B cell proliferative disorder in an individual in need thereof comprising a TEC inhibitor (e.g., an ITK inhibitor, a BTK inhibitor, e.g. a covalent BTK inhibitor,) and/or an anti-CD20 therapeutic agent. Disclosed herein, in certain embodiments, are compositions for treating a B cell proliferative disorder in an individual in need thereof comprising a covalent Btk inhibitor (e.g., an irreversible covalent BTK inhibitor, e.g., ibrutinib) and/or an anti-CD20 therapeutic agent. In some embodiments, the B cell proliferative disorder is refractory to the covalent BTK inhibitor (e.g., an irreversible covalent BTK inhibitor, e.g., ibrutinib). In some embodiments, the B cell proliferative disorder is relapsed. In some embodiments, the B cell proliferative disorder is mantle cell lymphoma.

[00223] In some embodiments, the covalent BTK inhibitor is a compound of Formula (A). In some embodiments, the covalent Btk inhibitor is (R)-l-(3-(4-amino-3-(4-phenoxyphenyl)-lH- pyrazolo[3 ,4-d]pyrimidin- 1 -yl)piperidin- 1 -yl)prop-2-en- 1 -one (i. e. PCI-32765/ibrutinib).

[00224] Pharmaceutical compositions of covalent Btk inhibitors (e.g., an irreversible covalent Btk inhibitor, e.g., ibrutinib) and/or anti-CD20 therapeutic agents are formulated in a

conventional manner using one or more physiologically acceptable carriers including excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. A summary of pharmaceutical compositions described herein is 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 & Wilkinsl999). [00225] A pharmaceutical composition, as used herein, refers to a mixture of a covalent Btk inhibitor (e.g., an irreversible covalent Btk inhibitor, e.g., ibrutinib) and/or an anti-CD20 therapeutic agent with other chemical components, such as carriers, stabilizers, diluents, dispersing agents, suspending agents, thickening agents, and/or excipients.

[00226] Pharmaceutical compositions are optionally 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.

[00227] In certain embodiments, compositions may also include one or more pH adjusting agents or buffering agents, including acids such as acetic, boric, citric, lactic, phosphoric and hydrochloric acids; bases such as sodium hydroxide, sodium phosphate, sodium borate, sodium citrate, sodium acetate, sodium lactate and tris-hydroxymethylaminomethane; and buffers such as citrate/dextrose, sodium bicarbonate and ammonium chloride. Such acids, bases and buffers are included in an amount required to maintain pH of the composition in an acceptable range.

[00228] In other embodiments, compositions may also include one or more salts in an amount required to bring osmolality of the composition into an acceptable range. Such salts include those having sodium, potassium or ammonium cations and chloride, citrate, ascorbate, borate, phosphate, bicarbonate, sulfate, thiosulfate or bisulfite anions; suitable salts include sodium chloride, potassium chloride, sodium thiosulfate, sodium bisulfite and ammonium sulfate.

[00229] The term "pharmaceutical combination" as used herein, means a product that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed combinations of the active ingredients. The term "fixed combination" means that the active ingredients, e.g. a compound described herein and a co-agent, are both administered to a patient simultaneously in the form of a single entity or dosage. The term "non-fixed

combination" means that the active ingredients, e.g. a compound described herein and a co- agent, are administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific intervening time limits, wherein such administration provides effective levels of the two compounds in the body of the patient. The latter also applies to cocktail therapy, e.g. the administration of three or more active ingredients.

[00230] The pharmaceutical formulations described herein are administered by any suitable administration route, including but not limited to, oral, parenteral (e.g., intravenous, subcutaneous, intramuscular), intranasal, buccal, topical, rectal, or transdermal administration routes.

[00231] The pharmaceutical compositions described herein are formulated into any suitable dosage form, including but not limited to, aqueous oral dispersions, liquids, gels, syrups, elixirs, slurries, suspensions and the like, for oral ingestion by an individual to be treated, 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 some embodiments, the compositions are formulated into capsules. In some embodiments, the compositions are formulated into solutions (for example, for IV administration).

[00232] The pharmaceutical solid dosage forms described herein optionally include a compound described herein and one or more pharmaceutically acceptable additives such as a compatible carrier, binder, filling agent, suspending agent, flavoring agent, sweetening agent, disintegrating agent, dispersing agent, surfactant, lubricant, colorant, diluent, solubilizer, moistening agent, plasticizer, stabilizer, penetration enhancer, wetting agent, anti-foaming agent, antioxidant, preservative, or one or more combination thereof.

[00233] In still other aspects, using standard coating procedures, such as those described in Remington's Pharmaceutical Sciences, 20th Edition (2000), a film coating is provided around the compositions. In some embodiments, the compositions are formulated into particles (for example for administration by capsule) and some or all of the particles are coated. In some embodiments, the compositions are formulated into particles (for example for administration by capsule) and some or all of the particles are microencapsulated. In some embodiments, the compositions are formulated into particles (for example for administration by capsule) and some or all of the particles are not microencapsulated and are uncoated.

[00234] In certain embodiments, compositions provided herein may also 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. [00235] "Antifoaming agents" reduce foaming during processing which can result in coagulation of aqueous dispersions, bubbles in the finished film, or generally impair processing. Exemplary anti-foaming agents include silicon emulsions or sorbitan sesquoleate.

[00236] "Antioxidants" include, for example, butylated hydroxytoluene (BHT), sodium ascorbate, ascorbic acid, sodium metabisulfite and tocopherol. In certain embodiments, antioxidants enhance chemical stability where required.

[00241] Combinations of one or more erosion facilitator with one or more diffusion facilitator can also be used in the present compositions.

[00242] The term "diluent" refers to chemical compounds that are used to dilute the compound of interest prior to delivery. Diluents can also be used to stabilize compounds because they can provide a more stable environment. Salts dissolved in buffered solutions (which also can provide pH control or maintenance) are utilized as diluents in the art, including, but not limited to a phosphate buffered saline solution. In certain embodiments, diluents increase bulk of the composition to facilitate compression or create sufficient bulk for homogenous blend for capsule filling.

[00244] "Drug absorption" or "absorption" typically refers to the process of movement of drug from site of administration of a drug across a barrier into a blood vessel or the site of action, e.g., a drug moving from the gastrointestinal tract into the portal vein or lymphatic system.

[00245] An "enteric coating" is a substance that remains substantially intact in the stomach but dissolves and releases the drug in the small intestine or colon. Generally, the enteric coating comprises a polymeric material that prevents release in the low pH environment of the stomach but that ionizes at a higher pH, typically a pH of 6 to 7, and thus dissolves sufficiently in the small intestine or colon to release the active agent therein.

[00246] "Erosion facilitators" include materials that control the erosion of a particular material in gastrointestinal fluid. Erosion facilitators are generally known to those of ordinary skill in the art. Exemplary erosion facilitators include, e.g., hydrophilic polymers, electrolytes, proteins, peptides, and amino acids.

All formulations for oral administration should be in dosages suitable for such administration.

[00266] In some embodiments, the solid dosage forms disclosed herein may be 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 (including a sterile packaged powder, a dispensable powder, or an effervescent powder) a capsule (including both soft or hard capsules, e.g., capsules made from animal-derived gelatin or plant-derived HPMC, or "sprinkle capsules"), solid dispersion, solid solution, bioerodible dosage form, controlled release formulations, pulsatile release dosage forms, multiparticulate dosage forms, pellets, granules, or an aerosol. In other embodiments, the pharmaceutical formulation is in the form of a powder. In still other embodiments, the pharmaceutical formulation is in the form of a tablet, including but not limited to, a fast-melt tablet. Additionally, pharmaceutical formulations described herein may be administered as a single capsule or in multiple capsule dosage form. In some embodiments, the pharmaceutical formulation is administered in two, or three, or four, capsules or tablets.

[00267] In some embodiments, solid dosage forms, e.g., tablets, effervescent tablets, and capsules, are prepared by mixing particles of ibrutinib and/or an anticancer agent, with one or more pharmaceutical excipients to form a bulk blend composition. When referring to these bulk blend compositions as homogeneous, it is meant that the particles of ibrutinib and/or an anticancer agent, are dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms, such as tablets, pills, and capsules. The individual unit dosages may also include film coatings, which disintegrate upon oral ingestion or upon contact with diluent. These formulations can be manufactured by conventional pharmacological techniques.

[00268] Conventional pharmacological techniques include, e.g., one or a combination of methods: (1) dry mixing, (2) direct compression, (3) milling, (4) dry or non-aqueous granulation, (5) wet granulation, or (6) fusion. See, e.g., Lachman et al., The Theory and Practice of

Industrial Pharmacy (1986). Other methods include, e.g., spray drying, pan coating, melt granulation, granulation, fluidized bed spray drying or coating (e.g., wurster coating), tangential coating, top spraying, tableting, extruding and the like.

[00282] 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 described herein. The amounts of such additives can be readily determined by one skilled in the art, according to the particular properties desired.

[00283] In other embodiments, one or more layers of the pharmaceutical formulation are plasticized. Illustratively, a plasticizer is generally a high boiling point solid or liquid. Suitable plasticizers can be added from about 0.01% to about 50% by weight (w/w) of the coating composition.

embodiments, the compressed tablets will include a film surrounding the final compressed tablet. In some embodiments, the film coating can provide a delayed release of ibrutinib or the second 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 other embodiments, the compressed tablets include one or more excipients.

[00285] A capsule may be prepared, for example, by placing the bulk blend of the formulation of ibrutinib or the second agent, described above, 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 may be swallowed whole or the capsule may be opened and the contents sprinkled on food prior to eating. In some embodiments, the therapeutic dose is split into multiple (e.g., two, three, or four) capsules. In some embodiments, the entire dose of the formulation is delivered in a capsule form. [00286] In various embodiments, the particles of ibrutinib and/or an anticancer agent, 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.

Furthermore, other methods such as roller compaction, extrusion/spheronization, coacervation, or nanoparticle coating may also be used.

[00292] In one embodiment, the particles of compounds of any of ibrutinib or an anticancer agent are microencapsulated prior to being formulated into one of the above forms. In still another embodiment, some or most of the particles are coated prior to being further formulated by using standard coating procedures, such as those described in Remington 's Pharmaceutical Sciences, 20th Edition (2000).

[00293] In other embodiments, the solid dosage formulations of the compounds of any of ibrutinib and/or an anticancer agent are plasticized (coated) with one or more layers.

Illustratively, a plasticizer is generally a high boiling point solid or liquid. Suitable plasticizers can be added from about 0.01% to about 50% by weight (w/w) of the coating composition. Plasticizers include, but are not limited to, diethyl phthalate, citrate esters, polyethylene glycol, glycerol, acetylated glycerides, triacetin, polypropylene glycol, polyethylene glycol, triethyl citrate, dibutyl sebacate, stearic acid, stearol, stearate, and castor oil.

[00294] In other embodiments, a powder including the formulations with a compound of any of ibrutinib and/or an anticancer agent, described herein, may be formulated to include one or more pharmaceutical excipients and flavors. Such a powder may be prepared, for example, by mixing the formulation 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.

[00295] In still other embodiments, effervescent powders are also prepared in accordance with the present disclosure. Effervescent salts have been used to disperse medicines in water for oral administration. Effervescent salts are granules or coarse powders containing a medicinal agent in a dry mixture, usually composed of sodium bicarbonate, citric acid and/or tartaric acid. When salts of the compositions described herein are added to water, the acids and the base react to liberate carbon dioxide gas, thereby causing "effervescence." Examples of effervescent salts include, e.g., the following ingredients: sodium bicarbonate or a mixture of sodium bicarbonate and sodium carbonate, citric acid and/or tartaric acid. Any acid-base combination that results in the liberation of carbon dioxide can be used in place of the combination of sodium bicarbonate and citric and tartaric acids, as long as the ingredients were suitable for pharmaceutical use and result in a pH of about 6.0 or higher.

[00296] In some embodiments, the solid dosage forms described herein can be 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 of the gastrointestinal tract. The enteric coated dosage form may be 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. The enteric coated oral dosage form may also be a capsule (coated or uncoated) containing pellets, beads or granules of the solid carrier or the composition, which are themselves coated or uncoated.

[00297] The term "delayed release" as used herein refers to the delivery so that the release can be accomplished at some generally predictable location in the intestinal tract more distal to that which would have been accomplished if there had been no delayed release alterations. In some embodiments the method for delay of release is coating. 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. It is expected that any anionic polymer exhibiting a pH-dependent solubility profile can be used as an enteric coating in the methods and compositions described herein to achieve delivery to the lower gastrointestinal tract. In some embodiments the polymers described herein are anionic carboxylic polymers. In other embodiments, the polymers and compatible mixtures thereof, and some of their properties, include, but are not limited to:

[00298] Shellac, also called purified lac, a refined product obtained from the resinous secretion of an insect. This coating dissolves in media of pH >7;

[00299] Acrylic polymers. The performance of acrylic polymers (primarily their solubility in biological fluids) can vary based on the degree and type of substitution. 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;

[00300] Cellulose Derivatives. Examples of suitable cellulose derivatives are: ethyl cellulose; reaction mixtures of partial acetate esters of cellulose with phthalic anhydride. The performance can vary based on the degree and type of substitution. Cellulose acetate phthalate (CAP) dissolves in pH >6. Aquateric (FMC) is an aqueous based system and is a spray dried CAP psuedolatex with particles <1 μιη. Other components in Aquateric can include pluronics, Tweens, and acetylated monoglycerides. Other suitable cellulose derivatives include: cellulose acetate trimellitate (Eastman); methylcellulose (Pharmacoat, Methocel); hydroxypropylmethyl cellulose phthalate (HPMCP); hydroxypropylmethyl cellulose succinate (HPMCS); and hydroxypropylmethylcellulose acetate succinate (e.g., AQOAT (Shin Etsu)). The performance can vary based on the degree and type of substitution. For example, HPMCP such as, HP-50, HP-55, HP-55S, HP-55F grades are suitable. The performance can vary based on the degree and type of substitution. For example, suitable grades of hydroxypropylmethylcellulose acetate succinate include, but are not limited to, AS-LG (LF), which dissolves at pH 5, AS-MG (MF), which dissolves at pH 5.5, and AS-HG (HF), which dissolves at higher pH. These polymers are offered as granules, or as fine powders for aqueous dispersions; Poly Vinyl Acetate Phthalate (PVAP). PVAP dissolves in pH >5, and it is much less permeable to water vapor and gastric fluids.

[00301] In some embodiments, the coating can, and usually does, contain a plasticizer and possibly other coating excipients such as colorants, talc, and/or magnesium stearate, which are well known in the art. Suitable plasticizers include triethyl citrate (Citroflex 2), triacetin

(glyceryl triacetate), acetyl triethyl citrate (Citroflec A2), Carbowax 400 (polyethylene glycol 400), diethyl phthalate, tributyl citrate, acetylated monoglycerides, glycerol, fatty acid esters, propylene glycol, and dibutyl phthalate. In particular, anionic carboxylic acrylic polymers usually will contain 10-25% by weight of a plasticizer, especially dibutyl phthalate, polyethylene glycol, triethyl citrate and triacetin. 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.

[00302] Colorants, detackifiers, surfactants, antifoaming agents, lubricants (e.g., carnuba wax or PEG) may be added to the coatings besides plasticizers to solubilize or disperse the coating material, and to improve coating performance and the coated product.

[00303] In other embodiments, the formulations described herein, which include ibrutinib and/or an anticancer agent, 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. Many other types of controlled release systems known to those of ordinary skill in the art and are suitable for use with the formulations described herein. Examples of such delivery systems include, e.g., polymer-based systems, such as polylactic and polygly colic acid, plyanhydrides and polycaprolactone; porous matrices, nonpolymer-based systems that are lipids, including sterols, such as cholesterol, cholesterol esters and fatty acids, or neutral fats, such as mono-, di- and triglycerides; hydrogel release systems; silastic systems; peptide-based systems; wax coatings, bioerodible dosage forms, compressed tablets using conventional binders and the like. See, e.g., Liberman et al.,

[00310] Suitable preservatives for the aqueous suspensions or dispersions described herein include, for example, potassium sorbate, parabens (e.g., methylparaben and propylparaben), benzoic acid and its salts, other esters of parahydroxybenzoic acid such as butylparaben, alcohols such as ethyl alcohol or benzyl alcohol, phenolic compounds such as phenol, or quaternary compounds such as benzalkonium chloride. Preservatives, as used herein, are incorporated into the dosage form at a concentration sufficient to inhibit microbial growth.

[00311] Suitable viscosity enhancing agents for the aqueous suspensions or dispersions described herein include, but are not limited to, methyl cellulose, xanthan gum, carboxymethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, Plasdon^® S-630, carbomer, polyvinyl alcohol, alginates, acacia, chitosans and combinations thereof. The concentration of the viscosity enhancing agent will depend upon the agent selected and the viscosity desired.

[00312] Examples of sweetening agents suitable for the aqueous suspensions or dispersions described herein include, for example, acacia syrup, acesulfame K, alitame, anise, apple, aspartame, banana, Bavarian cream, berry, black currant, butterscotch, calcium citrate, camphor, caramel, cherry, cherry cream, chocolate, cinnamon, bubble gum, citrus, citrus punch, citrus cream, cotton candy, cocoa, cola, cool cherry, cool citrus, cyclamate, cylamate, dextrose, eucalyptus, eugenol, fructose, fruit punch, ginger, glycyrrhetinate, glycyrrhiza (licorice) syrup, grape, grapefruit, honey, isomalt, lemon, lime, lemon cream, monoammonium glyrrhizinate (MagnaSweet ), maltol, mannitol, maple, marshmallow, menthol, mint cream, mixed berry, neohesperidine DC, neotame, orange, pear, peach, peppermint, peppermint cream, Prosweet^® Powder, raspberry, root beer, rum, saccharin, safrole, sorbitol, spearmint, spearmint cream, strawberry, strawberry cream, stevia, sucralose, sucrose, sodium saccharin, saccharin, aspartame, acesulfame potassium, mannitol, talin, sucralose, sorbitol, swiss cream, tagatose, tangerine, thaumatin, tutti fruitti, vanilla, walnut, watermelon, wild cherry, wintergreen, xylitol, or any combination of these flavoring ingredients, e.g., anise-menthol, cherry-anise, cinnamon-orange, cherry-cinnamon, chocolate-mint, honey-lemon, lemon-lime, lemon-mint, menthol-eucalyptus, orange-cream, vanilla-mint, and mixtures thereof. In one embodiment, the aqueous liquid dispersion can comprise a sweetening agent or flavoring agent in a concentration ranging from about 0.001% to about 1.0% the volume of the aqueous dispersion.

In yet another embodiment, the aqueous liquid dispersion can comprise a sweetening agent or flavoring agent in a concentration ranging from about 0.01% to about 1.0% the volume of the aqueous dispersion.

[00313] In addition to the additives listed above, the liquid formulations can also include inert diluents commonly used in the art, such as water or other solvents, solubilizing agents, and emulsifiers.

[00314] In some embodiments, the pharmaceutical formulations described herein can be 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 can be 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. SEDDS may provide improvements in the bioavailability of hydrophobic active ingredients. Methods of producing self-emulsifying dosage forms are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and 6,960,563, each of which is specifically incorporated by reference.

[00315] It is to be appreciated that there is overlap between the above-listed additives used in the aqueous dispersions or suspensions described herein, since a given additive is often classified differently by different practitioners in the field, or is commonly used for any of several different functions. Thus, the above-listed additives should be taken as merely exemplary, and not limiting, of the types of additives that can be included in formulations described herein. The amounts of such additives can be readily determined by one skilled in the art, according to the particular properties desired.

Intranasal Formulations

[00316] Intranasal formulations are known in the art and are described in, for example, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452, each of which is specifically incorporated by reference. Formulations that include ibrutinib and/or An anticancer agent, which are prepared according to these and other techniques well-known in the art 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, a standard reference in the field. The choice of suitable carriers is highly 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 may also be present. The nasal dosage form should be isotonic with nasal secretions. [00317] For administration by inhalation described herein may be in a form 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 nebulizer, 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 compound described herein and a suitable powder base such as lactose or starch.

Buccal Formulations

[00318] Buccal formulations may be 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, each of which is specifically incorporated by reference. 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. The buccal dosage form is fabricated so as to erode gradually over a predetermined time period, wherein the delivery is provided essentially throughout. Buccal drug delivery, as will be appreciated by those skilled in the art, avoids the disadvantages encountered with oral drug administration, e.g., slow absorption, degradation of the active agent by fluids present in the gastrointestinal tract and/or first-pass inactivation in the liver. With regard to the bioerodible (hydrolysable) polymeric carrier, it will be appreciated that virtually any such carrier can be used, so long as the desired drug release profile is not compromised, and the carrier is compatible with ibrutinib and/or An anticancer agent, and any other components that may be present in the buccal dosage unit. Generally, the polymeric carrier comprises hydrophilic (water-soluble and water-swellable) polymers that adhere to the wet surface of the buccal mucosa. Examples of polymeric carriers useful herein include acrylic acid polymers and co, e.g., those known as "carbomers" (Carbopol^®, which may be obtained from B.F. Goodrich, is one such polymer). Other components may also be incorporated into the buccal dosage forms described herein include, but are not limited to, disintegrants, diluents, binders, lubricants, flavoring, colorants, preservatives, and the like. For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, or gels formulated in a conventional manner. Transdermal Formulations

[00319] Transdermal formulations described herein may be administered using a variety of devices which have been described in the art. For example, such devices include, but are not limited to, U.S. Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683, 3,742,951, 3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073, 3,996,934, 4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211, 4,230,105, 4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280, 5,869,090, 6,923,983, 6,929,801 and 6,946,144, each of which is specifically incorporated by reference in its entirety.

[00320] The transdermal dosage forms described herein may incorporate certain

pharmaceutically acceptable excipients which are conventional in the art. In one embodiments, the transdermal formulations described herein include at least three components: (1) a formulation of a compound of ibrutinib and An anticancer agent; (2) a penetration enhancer; and (3) an aqueous adjuvant. In addition, transdermal formulations can include additional components such as, but not limited to, gelling agents, creams and ointment bases, and the like. In some embodiments, the transdermal formulation can further include a woven or non-woven backing material to enhance absorption and prevent the removal of the transdermal formulation from the skin. In other embodiments, the transdermal formulations described herein can maintain a saturated or supersaturated state to promote diffusion into the skin.

[00321] Formulations suitable for transdermal administration of compounds described herein may employ transdermal delivery devices and transdermal delivery patches and can be lipophilic emulsions or buffered, aqueous solutions, dissolved and/or dispersed in a polymer or an adhesive. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. Still further, transdermal delivery of the compounds described herein can be accomplished by means of iontophoretic patches and the like. Additionally, transdermal patches can provide controlled delivery of ibrutinib and An anticancer agent. The rate of absorption can be slowed by using rate-controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption. An absorption enhancer or carrier can include absorbable pharmaceutically acceptable solvents to assist passage through the skin. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin.

Injectable Formulations

[00322] Formulations that include a compound of ibrutinib and/or An anticancer agent, suitable for intramuscular, subcutaneous, or intravenous injection may 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 including 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. Formulations suitable for subcutaneous injection may 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. It may also be 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.

[00323] For intravenous injections, compounds described herein may be 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 may include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients. Such excipients are generally known in the art.

[00324] 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. Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

Other Formulations

[00325] In certain embodiments, delivery systems for pharmaceutical compounds may be employed, such as, for example, liposomes and emulsions.

[00326] In some embodiments, the compounds described herein may be administered topically and can be formulated into a variety of topically administrable compositions, such as solutions, suspensions, lotions, gels, pastes, medicated sticks, balms, creams or ointments. Such

pharmaceutical compounds can contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.

[00327] The compounds described herein may also be formulated in rectal compositions such as enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, or retention enemas, containing conventional suppository bases such as cocoa butter or other glycerides, as well as synthetic polymers such as polyvinylpyrrolidone, PEG, and the like. In suppository forms of the compositions, a low-melting wax such as, but not limited to, a mixture of fatty acid glycerides, optionally in combination with cocoa butter is first melted.

[00328] In some embodiments, the pharmaceutical compositions are formulated such that the amount of the covalent Btk inhibitor (e.g., an irreversible covalent Btk inhibitor, e.g., ibrutinib) in each unit dosage form is about 140 mg per. Kits/Article of Manufacture

EXAMPLES

[00335] These examples are provided for illustrative purposes only and not to limit the scope of the claims provided herein.

Example 1: Safety and Activity of BTK Inhibitor Ibrutinib Combined With Ofatumumab in Patients with Chronic Lymphocytic Leukemia

[00336] Chronic lymphocytic leukemia (CLL) is the most prevalent form of leukemia among adults in Western countries with increasing incidence in older individuals; median age of diagnosis is 72 years. It is estimated that 15,720 new cases of CLL will be diagnosed and 4,600 deaths due to the malignancy will occur in the US during 2014. CLL is characterized by an accumulation of malignant monoclonal B cells in the bone marrow, blood, lymph nodes, and other lymphoid tissues. Small lymphocytic lymphoma (SLL), immunophenotypically and morphologically identical to CLL, is characterized by a similar accumulation of cells without the leukemic component.

[00337] Treatment strategies for CLL have evolved from palliative approaches based on alkylating agents alone or in combination with purine analogue-based chemotherapy. More intensive approaches with the introduction of the anti-CD20 monoclonal antibody rituximab and its integration into combination chemotherapy regimens have led to long-term remissions in a significant proportion of patients. As a result, chemoimmunotherapy has become standard frontline treatment for fit patients with CLL. In general, CLL is incurable with current therapeutic regimens, and the treatment of relapsed disease remains challenging. Furthermore the presence of high-risk features such as unmutated IGHV, the chromosomal abnormality del(17)(pl3.1), or transformation to high-grade lymphoma are associated with poor outcomes even with aggressive chemoimmunotherapy .

[00338] Although CLL is a heterogeneous disease, commonalities in the pathways in the development of a B cell to a malignant cell and in the leukemic cells themselves have allowed the development of targeted therapies. During the last decades, the B-cell receptor (BCR) pathway has emerged as a new therapeutic target in B-cell malignancies. Lying proximal within this pathway, Bruton's tyrosine kinase (BTK), a member of the Tec kinase family, plays a central role in the activation of downstream signaling required for survival and proliferation of malignant B cells. BTK is also critical for B-cell development and function in relation to the homing, migration, and adhesion of B cells to bone marrow or lymphoid tissues.

[00339] Ibrutinib is a first-in-class, orally administered, once-daily covalent inhibitor of BTK. In preclinical models, ibrutinib induced apoptosis and decreased survival of CLL cells, and inhibited their homing, migration, and adhesion to the tumor microenvironment. In a multicenter phase lb/2 study, single-agent ibrutinib resulted in an investigator-assessed overall response rate (ORR) of 71% in patients with relapsed/refractory CLL, independent of the presence of high-risk clinical or genomic features. The estimated progression-free survival (PFS) at 26 months was 75%, indicating that responses to ibrutinib were durable. More recently, in the phase 3

RESONATE trial (PCYC-1112-CA), ibrutinib demonstrated a statistically significant 78% reduction in the risk of progression or death and a 56% reduction in the risk of death compared with ofatumumab in patients with relapsed/refractory CLL. Ibrutinib was approved by the FDA for treatment of patients with CLL who had received at least one prior therapy and for all patients with del(17)(pl3.1) CLL.

[00340] Ofatumumab is an anti-CD20 monoclonal antibody that binds to an epitope distinct from that for rituximab. It exhibits more potent complement-dependent cytotoxicity and NK-cell antibody dependent cellular cytotoxicity (ADCC) compared with rituximab in B-cell lines including CLL cells. The efficacy of ofatumumab was demonstrated in a phase 2 study in patients with fludarabine-refractory CLL, who were also refractory to alemtuzumab or had bulky disease unsuitable for treatment with alemtuzumab. Ofatumumab was also effective in patients previously treated with rituximab. Recent studies have shown the feasibility and activity of ofatumumab in combination with chemotherapy. Ofatumumab is approved in the US for treatment of CLL refractory to fludarabine and alemtuzumab, and in combination with chlorambucil for front-line treatment of CLL where fludarabine-based treatment is inappropriate.

[00341] The rationale for combining ibrutinib and ofatumumab is based on proven single-agent activity in relapsed/refractory CLL, distinct mechanisms of action, and non-overlapping toxicities. The present study was designed to evaluate the safety, tolerability, and efficacy of 3 different fixed-dose regimens of ibrutinib in combination with ofatumumab in patients with relapsed/refractory CLL and related diseases. Because it was not known whether the initial lymphocytosis commonly observed with ibrutinib would predispose to development of ofatumumab infusion-related reactions or tumor lysis syndrome (TLS), three different dosing sequences were evaluated: ibrutinib was started either 4 weeks before (group 1), 1 day before (group 2), or 8 weeks after ofatumumab (group 3).

Patients

[00342] Patients were enrolled between January 2011 and June 2012, and treated at The Ohio State University James Comprehensive Cancer Center after providing written informed consent. Patients were eligible if they had histologically confirmed CLL, SLL, B-cell prolymphocytic leukemia (PLL), as defined by the WHO classification of hematopoietic neoplasms, or Richter's transformation, and had an indication for treatment as defined by the 2008 revised International Workshop on Chronic Lymphocytic Leukemia (IWCLL) guidelines or required cytoreduction prior to stem cell transplant. Key eligibility criteria also included failure of >2 prior therapies including a nucleoside analogue (unless contraindicated); >10% expression of CD20 on

CLL/SLL cells by flow cytometry; ECOG performance status <2; and adequate end-organ function.

Study design and treatment plan

[00343] This phase lb/2, single-center, open-label, sequential-group study was approved by the institutional review board and conducted in accordance with the principles of the Declaration of Helsinki and the International Conference on Harmonization Guidelines for Good Clinical Practice. The study was registered on ClinicalTrials.gov (NCT01217749).

[00344] At screening, patients underwent a complete history, physical examination, testing of laboratory parameters, and assessment of prognostic factors (including IGHV mutational analysis and P2-microglobulin). Pretreatment assessments included flow cytometry, bone marrow evaluation, and computed tomography (CT) scan of the chest, abdomen and pelvis. A baseline PET/CT scan was performed for patients with SLL and Richter's transformation.

[00345] Study treatment was administered in 28-day cycles. Ibrutinib was administered orally at a dose of 420 mg once daily, and continued until disease progression or unacceptable toxicity. Ofatumumab was administered per prescribing information (300 mg for the first dose and 2000 mg for subsequent doses) intravenously for a total of 12 infusions. Patients could then continue daily ibrutinib in extension study PCYC-1103 until progression or intolerability. Patients receiving three different administration sequences were enrolled sequentially: group 1 with ibrutinib lead-in, group 2 with concomitant administration (ofatumumab on Day 1 and ibrutinib on Day 2), and group 3 with ofatumumab lead-in (Figure 1). After the first 6 patients in group 1 demonstrated no DLT (within 56 days), enrollment was expanded to 27 patients. Expansion of enrollment in group 2 was similarly guided by safety (<1 DLT among the first 6 patients observed for 28 days) and anti-tumor activity. Enrollment in group 2 and 3 began after enrollment was completed for groups 1 and 2, respectively.

[00346] Treatment was withheld for any grade 4 toxicity, or the individual drug was withheld for ibrutinib-related or ofatumumab-related, clinically significant, unmanageable grade 3 adverse events (AEs). Treatment was resumed after the AE returned to baseline or resolved.

[00347] Patients received premedication with acetaminophen 650 mg, cetirizine 10 mg or equivalent, and dexamethasone 20 mg intravenously prior to each dose of ofatumumab. For doses 3-12 of ofatumumab, the dexamethasone dose could be gradually reduced or discontinued if no > grade 3 infusion reactions occurred during prior doses. Patients considered at risk for TLS were to be hydrated and pretreated with anti-hyperuricemics as per standard ofatumumab guidance.³⁷ Use of standard supportive care treatments, e.g. hematopoietic growth factors, was permitted.

Assessments

[00348] Responses were assessed and reported by the investigators for patients with CLL and PLL according to IWCLL guidelines and for SLL and Richter's transformation according to the revised International Working Group criteria. A bone marrow evaluation was required to confirm a complete response (CR). An increase in peripheral blood absolute lymphocyte count (ALC) alone was not considered a treatment failure or progressive disease in the absence of other indications of disease progression. Lymphocytosis was defined as an increase in ALC of >50% from baseline and to an absolute value of >5 x 10⁹/L. Response evaluations were performed following cycles 1 and 3, and then every 3 cycles, including CT scans of the chest, abdomen, and pelvis. Safety assessments included laboratory evaluations and physical examination. Severity of AEs was defined using the Common Terminology Criteria for Adverse Events (version 4.0). Statistical considerations

[00349] Safety was evaluated in all patients who received at least one dose of study drug.

Efficacy was determined among evaluable patients who received at least one dose of one of the study drugs and had at least one tumor response assessment. The minimax Simon two-stage design was chosen to provide 85% power to reject the null hypothesis (for ORR of 50%) when using a 1 -sided 10% alpha-level test. An interim analysis was conducted for the first 10 evaluable patients in groups 1 and 2, and the group expanded only if >3 patients achieved objective responses during the first 3 cycles. Efficacy was evaluated in each group separately, with no formal statistical analysis planned to compare efficacy among sequentially enrolled groups.

[00350] The primary endpoints were the number of DLTs observed among the first 6 patients enrolled in groups 1 and 2, and ORR, including CR and partial response (PR), in all groups. Secondary endpoints included incidence of AEs, (including AEs leading to ibrutinib

discontinuation), > grade 3 AEs, serious AEs (SAEs), time to response, duration of response (DOR), PFS, and hematologic improvement. Kaplan-Meier methodology was used to estimate DOR and PFS; descriptive statistics were used for analysis of all other endpoints. Among patients with baseline cytopenias, hematologic improvement rate was evaluated as a secondary endpoint.

Results

Patients

[00351] A total of 71 patients were enrolled. Baseline characteristics varied among the 3 sequentially-enrolled groups (Table 1). Sixty-five patients (92%) had CLL, 1 (1%) SLL, 2 (3%) PLL, and 3 (4%) Richter's transformation. Median age was 64 years (range, 48-85 years) (Table 1). The majority (61%) had high-risk disease stage (Rai stage III or IV); 75% had bulky lymph nodes (>5 cm), 44% had del(17)(pl3.1), and 31% had del(l l)(q22.3). Baseline cytopenia was present in 70% of patients. Patients had received a median of 3 prior therapies (range, 2-13) that typically included an alkylating agent, purine analogue, and rituximab (Table 2).

[00352] All 71 patients received study treatment, 68 (96%) were evaluable for response, and 66 (93%) of them had CLL/SLL. Reasons for treatment discontinuation are shown in Table 3. Nine patients (13%) discontinued treatment due to progressive disease including 4 patients in Group 3 who had progressive disease during ofatumumab monotherapy; 7 (10%) discontinued due to AEs. Fifty-four patients (76%) continued ibrutinib treatment in a long-term extension study and 2 (3%) received allogeneic stem cell transplant. The median duration of ibrutinib therapy until transition to the long-term extension study was 15.8 months in group 1, 11.3 months in group 2, and 9.2 months in group 3 (Table 3), which reflects the sequential-group design with group 1 dosed earlier than groups 2 and 3 and modification of the long-term extension study that allowed earlier enrollment for the later group. The median duration of ofatumumab treatment was similar for all 3 groups (median of 5.6 months).

Safety

[00353] No DLTs occurred. The most common treatment-emergent AEs were diarrhea (70%), infusion-related reactions (45%), peripheral sensory neuropathy (44%) and stomatitis (38%) (Table 4). These AEs were mostly grade 1 or 2. Overall, 45 patients (63%) had > grade 3 AEs, the most common events being neutropenia (24%), pneumonia (17%), and diarrhea (7%). Only 1 grade 3 infusion reaction was reported in all 71 patients. Eight patients (11%) had AEs that led to ibrutinib discontinuation, 3 patients each in groups 1 and 2, and 2 patients in group 3.

[00354] Overall, 31 patients (44%) had SAEs, including 12 (44%) in group 1, 9 (45%) in group 2, and 10 (42%) in group 3. The most common SAEs included pneumonia (16%) and atrial fibrillation (6%). Seven patients (10%) had protocol-defined major bleeding events. Seven patients experienced a major hemorrhagic event, one of which (subdural hematoma) had a fatal outcome. Four of the 7 major hemorrhages were post-procedural; 2 of the 4 procedures occurred without a prior ibrutinib dose hold that is currently recommended. The 7 events were grade 3 hemothorax (after thoracentesis for symptomatic, recurrent pleural effusion, n=l), grade 3 post- procedural hemorrhage (sinus surgery, n=l, bone marrow biopsy, n=l), grade 3 hematoma (in the knee [Baker's cyst], post-surgical; n=l), grade 2 gastrointestinal hemorrhage (due to gastric ulcer; n=l), grade 3 gastrointestinal hemorrhage (due to esophageal varices hemorrhage in a patient with ongoing medical history of esophageal varices; n=l), and subdural hematoma (n=l). The patient who experienced a subdural hematoma was taking warfarin and enoxaparin as thromboprophylaxis during the study due to a recent history of deep vein thrombosis. Other fatal non-PD events within 30 days of the last dose of study treatment occurred in 6 patients including pneumonia (n=2), organizing pneumonia (n=l), cardiorespiratory arrest (n=l), ischemic stroke (n=l), and sepsis (n=l).

Efficacy

[00355] The ORR among patients with CLL/SLL was 100% (95% CI: 85.2%-100%) in group 1, 78.9% (95% CI: 54.4%-93.9%) in group 2, and 70.8% (95% CI: 48.9%-87.4%) in group 3. Among all CLL/SLL patients, the ORR was 83.3% (95% CI: 72.1%-91.4%). One patient (1.5%) achieved a CR and 54 patients (81.8%) achieved a PR. Two additional patients (3%) had a PR with lymphocytosis (PR-L). Best response among patients with CLL/SLL is shown in Figure 2A. Both PLL patients responded to treatment with best responses of CR and PR, with DORs of 9.2+ and 11.3+ months, respectively, continued on ibrutinib in the long-term extension study, and were in response at the time of this report. Two of the patients with Richter's transformation had stable disease for 471 and 137 days before developing disease progression; 1 other patient with Richter's transformation had a best response of PR (DOR 4.6 months) before developing disease progression on Day 168. Four patients (17%) in group 3 progressed on ofatumumab monotherapy before initiating ibrutinib. The presence of high-risk features did not appear to mitigate efficacy. ORR was 71% in patients >65 years, 79% in Rai stage III/IV, 85% in bulky disease (>5 cm lymph nodes), 90% in unmutated IGHV, 87% in del(17)(pl3.1), and 75% in patients with P2-microglobulin >3 mg/L (Figure 2B).

[00356] Overall, 37 of 70 patients (53%) developed lymphocytosis, including 17 (63%) in group 1, 11 (55%) in group 2, and 9 (39%) in group 3. The median percentage change in ALC over time is depicted in Figure 2C. The median time to peak ALC was 3.1 weeks in group 1, 1.1 weeks in group 2, and 13.1 weeks in group 3, reflecting the dosing schedule. At the time of analysis, lymphocytosis resolved in all patients in group 1 within a median time to resolution of 12.1 weeks; in 9 of 11 patients in group 2 (median time to resolution: 7.6 weeks); and in 6 of 9 patients in group 3 (median time to resolution: 21.1 weeks). A reduction in lymph node size was noted for all groups (Figure 2D). As expected, concomitant lymphocytosis was more pronounced for patients in group 1 than group 2 and 3 due to the later start of ofatumumab treatment; in all groups, ALC decreased over time.

[00357] Overall, 39 of 50 patients (78%) who had baseline cytopenias showed improvement in at least one hematologic parameter. Sustained hematologic improvement (defined as >50% improvement above baseline values or ANC >1500^L or hemoglobin >11 g/dL or platelets >100,000^L lasting >56 days without transfusion or use of growth factors) was seen in 12 of 20 patients (60%) with baseline neutropenia, 18 of 33 patients (55%) with anemia, and 25 of 36 patients (69%) with thrombocytopenia.

[00358] Among the 58 patients who responded to study treatment across diseases, the median time to initial response was 2.8 months (range, 1-6) in group 1, 1 month (range, 1-3.1) in group 2, and 2.8 months (range, 2.7-7.4) in group 3. Both patients who achieved a CR did so at 12.2 months. The median DOR has not yet been reached for the overall study population or individual groups. At 12 months, the estimated rate of continued response was 88.9% (95% CI: 74.3-95.4). At the end of the study, 52 responding patients (89.7%) remained alive and progression-free.

[00359] At a median time on study of 12.5 months, median PFS had not yet been reached; median follow-up was 16.4, 11.8, and 11.1 months for group 1, 2, and 3, respectively. The majority (76%) of patients continued on ibrutinib in a long-term extension study and 2 patients (2.8%) had a stem-cell transplant. The estimated 12-month PFS rate was 83.1% (95% CI:

72.1%-90%) for the entire study population, and 88.7% (95% CI: 69.0%-96.2%) in group 1, 85% (60.4%-94.9%) in group 2, and 75% (95% CI: 52.6%-87.9%) in group 3 (Figure 3).

Estimated 12-month OS was 88.6% (95% CI: 78.6%-94.2%) for the entire study population, and 92.3% (95% CI: 72.5%-98%) in group 1, 85% (95% CI: 60.4%-94.9%) in group 2, and 87.5% (95% CI: 66.1%-95.8%) in group 3.

[00360] Discussion

[00361] Herein, we demonstrate in a phase lb/2 study that ibrutinib and ofatumumab showed high clinical activity in patients with relapsed/refractory CLL/SLL in all 3 dose administration sequences investigated. These patients were heavily pretreated with a median of 3 prior therapies, and the majority had high-risk disease features. The response rates in all 3 groups were substantially higher than expected based on the previous experience with single-agent ofatumumab or ibrutinib at this short follow up time.²⁴'³¹ Response to therapy was highest in the group that received ibrutinib for a month prior to ofatumumab. In contrast, response was lowest among patients receiving the lead-in with ofatumumab, possibly reflective of the diminished efficacy of this treatment compared to ibrutinib as recently demonstrated in the randomized phase 3 RESONATE™ trial in previously treated patients with CLL.²⁵ Toxicity was similar among all groups. Although direct comparison of the 3 groups is not possible based upon lack of randomization and different pre-treatment features of the patients in each group, investigators in this study have chosen to pursue the schedule of group 1 with subsequent studies combining anti- CD20 antibodies as this schedule had the highest response rate and lowest rate of infusion reactions (33%, versus 70% in group 2 and 38% in group 3). Of note, all 3 schedules allowed the majority of patients to gain benefit from the combination. Concurrent administration of ibrutinib and rituximab has been reported with similar efficacy assessed by response as observed in this trial.⁴² The investigator- determined ORR for the CLL/SLL cohort was 83.3% with an additional 3% achieving partial response with lymphocytosis, which compares favorably to regimens used historically in the treatment of relapsed and/or refractory CLL. In the PCYC-1102-CA trial, the ORR (CR and PR) was 71% for both the ibrutinib 420-mg and 840-mg cohorts, and an additional

24

20% and 15% of patients, respectively, had a PR-L. Notably, the rate of PR-L with the combination (3%) is appreciably lower than in PCYC-1102-CA (14.8%). A recent 3-year update of the PCYC-1102-CA data demonstrated that 92% of patients who initially achieved a PR-L converted to conventional responses (PR/CR) with continued treatment with single-agent ibrutinib.⁴³ The median time to best response for responders was 2.8 months. In groups 1, 2, and 3, respectively, the time to best response was 3.8, 2.8, and 4.6 months. In distinction, the time to best response for relapsed or refractory patients treated with 420 mg on PCYC-1102-CA was 7.4 months.

[00362] The present study, which enrolled patients with PLL arising from CLL and also DLBCL (Richter's transformation), suggests the possibility of disease control with this combination regimen in patients with aggressive disease with the limitation that only 2 patients with PLL and 3 patients with Richter's transformation were treated. This is particularly true for PLL where 2 patients had durable remissions that persist at this time.

[00363] The high ORR of the combination was consistent across patient subgroups, even among patients with high-risk features such as del(17)(pl3.1), unmutated IGHV, and elevated β2- microglobulin levels. The mutated IGHV subgroup (n=8) showed a reduced ORR (50% vs. 90%) compared with the unmutated subgroup (n=50). Two of the 8 patients with mutated IGHV were in group 3 and progressed during ofatumumab monotherapy; both initiated ibrutinib and subsequently achieved PR and PR-L. The other 6 patients had PR (n=4), PR-L (n=l), and stable disease (n=l). Examination of PFS among different genetic groups will require further follow up, as the median PFS was not reached in any subgroup analyzed. Indeed, in the PCYC-1102-CA study, only patients with del(17)(pl3.1) or del(l l)(q22.3) demonstrated a tendency toward

43

progression, with PFS being the only difference that emerged over time.

[00364] Lymphocytosis is a well described pharmacodynamic class effect of BCR-inhibiting agents; with ibrutinib, this occurs by inhibition of BTK- mediated B-cell homing and adhesion to the tumor microenvironment, resulting in mobilization of leukemic cells from the lymph node compartment to the peripheral blood.²¹'²³ Lymphocytosis developed in 53% of the total population of the present study, with higher rates observed when ibrutinib was started 1 month before ofatumumab (group 1 : 63%), and lower rates when ofatumumab was started as monotherapy for 2 months (group 3: 39%). In previous phase 2 and 3 studies with single-agent ibrutinib, lymphocytosis developed in a higher proportion of patients (78% and 69% of patients with CLL/SLL, respectively) suggesting that the addition of an anti-CD20 monoclonal antibody may decrease the rate of lymphocytosis observed in ibrutinib-treated CLL patients.²⁴'²⁵ Temporal differences in lymphocytosis patterns across the 3 groups were expected, given the difference in the dosing sequence of ibrutinib relative to ofatumumab. Similar to reports of single-agent ibrutinib, the present study with ibrutinib and ofatumumab combined showed rapid and substantial decreases in lymph node size that occurred concomitantly with lymphocytosis.²⁴'⁴⁴ A recent analysis from the phase 2 trial of single-agent ibrutinib in patients with relapsed/refractory CLL showed that PR with prolonged lymphocytosis was not associated with inferior PFS outcomes compared with a traditional clinical response.⁴⁵ This finding with single-agent ibrutinib⁴⁵ along with data from the present study with the combination of ibrutinib and ofatumumab, and reported attenuation of lymphocytosis with the combination of ibrutinib and rituximab⁴⁶ raises an important question on whether additional targeting of lymphocytosis with anti-CD20 monoclonal antibodies improves long-term PFS/OS outcomes over single-agent ibrutinib therapy. This is currently being investigated in randomized studies including a phase 2 trial evaluating ibrutinib ± rituximab (NCT02007044) and the 3 -arm phase 3 ALLIANCE trial comparing rituximab and bendamustine, rituximab and ibrutinib, and ibrutinib monotherapy (NCT01886872).

[00365] The most common AEs (e.g., diarrhea, infusion-related reactions, contusion/bruising, upper respiratory tract infection) observed with the combination regimens were consistent with the safety profile of the single agents in previous trials. 24 ' 25 ' 31 Major bleeding events > grade 3 occurred in 6 patients (8%), which is consistent with the rate reported for single-agent ibrutinib in PCYC-1102-CA, albeit slightly higher than in the recent randomized RESONATE study of

24 25

single-agent ibrutinib (1%) versus ofatumumab (1.6%). ' Peripheral sensory neuropathy was reported at a relatively high rate (42%) in the present study. However, most cases were grade 1 or 2, and only 2 patients had grade 3 events. Peripheral sensory neuropathy was not a frequent AE in earlier single-agent studies with ibrutinib.²⁴'²⁵ However, in the randomized RESONATE study, peripheral sensory neuropathy (grade 1 and 2) was noted at a higher rate (13%) with ofatumumab compared with ibrutinib (4%).²⁵ These results suggest that while peripheral neuropathy may be associated with ofatumumab therapy, it may be exacerbated in combination with ibrutinib. Peripheral neuropathy was not commonly noted in other trials investigating anti- CD20 antibodies and ibrutinib (9% of patients treated with ibrutinib in combination with

42

rituximab). Generally, this complication did not limit the ability to administer either therapy as part of the current trial.
