Disclosed herein are crystalline forms of 2-[3-[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]piperidine-1-carbonyl]-4-methyl-4-[4-(oxetan-3-yl)piperazin-1-yl]pent-2-enenitrile (Compound (I)), methods of using the same, and processes for making Compound (I), including its various crystalline forms. The crystalline forms of Compound (I) are inhibitors of Bruton's tyrosine kinase (BTK). The enzyme BTK is a member of the Tec family of non-receptor tyrosine kinases.
BTK is expressed in most hematopoietic cells, including B cells, mast cells, and macrophages. BTK plays a role in the development and activation of B cells and has been implicated in multiple signaling pathways across a wide range of immune-mediated diseases. BTK activity has been implicated in the pathogenesis of several disorders and conditions, such as B cell-related hematological cancers (e.g., non-Hodgkin lymphoma and B cell chronic lymphocytic leukemia) and autoimmune diseases (e.g., rheumatoid arthritis, Sjogren's syndrome, pemphigus, inflammatory bowel disease, lupus, and asthma).
Compound (I) may inhibit BTK and be useful in the treatment of disorders and conditions mediated by BTK activity. Compound (I) is disclosed in Example 31 of WO 2014/039899 and has the following structure:
where *C is a stereochemical center. An alternative procedure for producing Compound (I) is described in Example 1 of WO 2015/127310.
Solid forms (e.g., crystalline forms) of bioactive compounds, such as Compound (I), are of interest in the pharmaceutical industry, where solid forms with specific physical, chemical, or pharmaceutical properties, such as solubility, dissociation, true density, dissolution, melting point, morphology, compaction behavior, particle size, flow properties, or solid state stability, may be desirable or even required for pharmaceutical development. Crystalline forms occur where the same composition of matter crystallizes in different lattice arrangements, resulting in different thermodynamic properties and stabilities specific to each crystalline form. Each unique crystal form is known as a “polymorph.”
While polymorphs of a given substance have the same chemical composition, they may differ from each other with respect to at least one physical, chemical, and/or pharmaceutical property, such as solubility, dissociation, true density, dissolution, melting point, crystal habit or morphology, compaction behavior, particle size, flow properties, and/or solid state stability. The solid state form of a bioactive compound often determines its ease of preparation, ease of isolation, hygroscopicity, stability, solubility, storage stability, ease of formulation, rate of dissolution in gastrointestinal fluids, and in vivo bioavailability.
It is not yet possible to predict the possible solid forms (e.g., crystalline forms) of a compound, whether any such forms will be suitable for commercial use in a pharmaceutical composition, or which form or forms will display desirable properties. Because different solid forms (e.g., crystalline forms) may possess different properties, reproducible processes for producing a substantially pure solid form are also desirable for bioactive compounds intended for use as pharmaceuticals.
Accordingly, there is a need for novel solid forms, including novel crystalline forms thereof, which are useful for treating disorders and conditions mediated by BTK activity, e.g., Compound (I), and reproducible, scalable methods of making the same.
Disclosed herein are novel crystalline forms of Compound (I), compositions comprising the same, and methods of using and making the same. In some embodiments, the novel crystalline forms disclosed herein have properties that are useful for large-scale manufacturing, pharmaceutical formulation, and/or storage.

As used herein, the term “TG-FTIR” refers to the analytical method of thermogravimetry coupled to Fourier transform infrared spectroscopy.
As used herein, the term “XRPD” refers to the analytical characterization method of X-ray powder diffraction. XRPD patterns can be recorded at ambient conditions in transmission or reflection geometry using a diffractometer.
As used herein, the terms “X-ray powder diffractogram,” “X-ray powder diffraction pattern,” and “XRPD pattern” refer to an experimentally obtained pattern plotting signal positions (on the abscissa) versus signal intensities (on the ordinate). For a crystalline material, an X-ray powder diffractogram may include at least one signal, each identified by its angular value as measured in degrees 2θ (° 2θ), depicted on the abscissa of an X-ray powder diffractogram, which may be expressed as “a signal at . . . degrees two-theta,” “a signal at [a] two-theta value(s) of . . . ” and/or “a signal at least . . . two-theta value(s) chosen from . . . .”
As used herein, the term “X-ray powder diffractogram having a signal at . . . two-theta values” refers to an XRPD pattern that contains X-ray reflection positions as measured and observed in X-ray powder diffraction experiments (° 2θ).
As used herein, the term “signal” refers to a point in the XRPD pattern where the intensity as measured in counts is at a local maximum. One of ordinary skill in the art would recognize that at least one signal in an XRPD pattern may overlap and may, for example, not be apparent to the naked eye. One of ordinary skill in the art would recognize that some art-recognized methods are capable of and suitable for determining whether a signal exists in a pattern, such as, e.g., Rietveld refinement.
As used herein, the terms “a signal at . . . degrees two-theta,” “a signal at [a] two-theta value[ ] of . . . ,” and “a signal at least . . . two-theta value(s) chosen from . . . ” refer to X-ray reflection positions as measured and observed in X-ray powder diffraction experiments (° 2θ). In some embodiments, the repeatability of the angular values is in the range of ±0.2° 2θ, i.e., the angular value can be at the recited angular value +0.2 degrees two-theta, the angular value −0.2 degrees two-theta, or any value between those two end points (angular value +0.2 degrees two-theta and angular value −0.2 degrees two-theta). It is well known to one of ordinary skill in the art that there can be variability in the measurements of X-ray powder diffraction signal values.
As such, a person of ordinary skill in the art would appreciate that there may be variability of up to ±0.2° 2θ in signal value for the same signal in different samples. Additionally, it is well known to one of ordinary skill in the art that there can be variability in the measurements of relative signal intensities in X-ray powder diffraction experiments. Illustratively, non-limiting factors that can affect the relative signal intensities include sample thickness and preferred orientation (e.g., the crystalline particles are not distributed randomly).
As used herein, an X-ray powder diffractogram is “substantially similar to that in [a particular] FIG.” when at least 90%, such as at least 95%, at least 98%, or at least 99%, of the signals in the two diffractograms are the same ±0.2° 2θ. In determining “substantial similarity,” one of ordinary skill in the art will understand that there may be variation in the intensities and/or signal positions in XRPD diffractograms even for the same crystalline form. Thus, those of ordinary skill in the art will understand that the signal maximum values in XRPD diffractograms (in degrees two-theta (° 2θ) referred to herein) generally mean that value reported ±0.2 degrees 2θ of the reported value, an art-recognized variance discussed above.
As stated above, described herein are novel crystalline forms of Compound (I). These novel crystalline forms may be inhibitors of BTK. BTK inhibitors are useful in the treatment of diseases mediated by BTK, such as, e.g., pemphigus vulgaris, pemphigus foliaceus, and immune thrombocytopenia.

Pemphigus is a rare B cell-mediated autoimmune disease that causes debilitating intraepithelial blisters and erosions on the skin and/or mucous membranes. Pemphigus carries a 10% mortality, generally due to infections arising from compromised tissues and treatment side effects and affects approximately 0.1 to 0.5 people out of 100,000 each year (Scully et al., 2002; Scully et al., 1999). The characteristic intraepidermal blisters observed in pemphigus patients are caused by the binding of IgG autoantibodies to certain keratinocyte desmosomal adhesion proteins, desmogleins 1 and 3 (Dsg1 and Dsg3), resulting in loss of cell adhesion (Amagai M et al., 2012; Diaz L A et al., 2000). B cells play key roles in the production of these autoantibodies and in cellular tolerance mechanisms.
Immune thrombocytopenia (commonly referred to as ITP) is characterized by autoantibody-mediated destruction of platelets and impaired platelet production, which result in thrombocytopenia and a predisposition to bleeding associated with morbidity and mortality.
There is preliminary evidence to support the role of BTK inhibition in patients with autoimmune cytopenias (Rogers 2016, Montillo 2017), where sequential episodes of severe autoimmune hemolytic anemia and ITP ceased after initiation of treatment with ibrutinib, a BTK/EGFR/ITK inhibitor, in patients with chronic lymphatic leukemia (CLL).
The crystalline forms described herein are useful as active pharmaceutical ingredients (APIs), as well as materials for preparing pharmaceutical compositions that incorporate one or more pharmaceutically acceptable excipients and are suitable for administration to human subjects. In some embodiments, these pharmaceutical compositions will be a pharmaceutical product, such as, e.g., a solid oral dosage form, such as tablets and/or capsules.
In some embodiments, the present disclosure provides a pharmaceutical composition comprising at least one crystalline form of Compound (I). In some embodiments, the present disclosure provides a pharmaceutical composition comprising at least one crystalline form of Compound (I) and at least one additional pharmaceutically acceptable excipient. Each excipient must be “pharmaceutically acceptable” in the sense of being compatible with the subject composition and its components not being injurious to the patient. Except insofar as any conventional pharmaceutically acceptable excipient is incompatible with Compound (I), such as, e.g., by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutically acceptable composition, its use is contemplated to be within the scope of this disclosure.
Some non-limiting examples of materials which may serve as pharmaceutically acceptable excipients include: (1) sugars, such as lactose, glucose, and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose, and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil, and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol, and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations.

Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, the contents of each of which is incorporated by reference herein, also discloses additional non-limiting examples of pharmaceutically acceptable excipients, as well as known techniques for preparing and using the same.
Pharmaceutical compositions disclosed herein may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally, or via an implanted reservoir. The term “parenteral,” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional, and intracranial injection or infusion techniques. In some embodiments, the compositions of the disclosure are administered orally, intraperitoneally, or intravenously. Sterile injectable forms of the pharmaceutical compositions of this disclosure may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium.
For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives, are useful in the preparation of injectables, as are natural pharmaceutically acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tween, Spans, and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.
Pharmaceutical compositions disclosed herein may also be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions, or solutions. When aqueous suspensions are required for oral use, the active ingredient is typically combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring, or coloring agents may also be added.
Alternatively, pharmaceutical compositions disclosed herein may be administered in the form of suppositories for rectal administration. Suppositories can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include, but are not limited to, cocoa butter, beeswax, and polyethylene glycols.
The pharmaceutical compositions of this disclosure may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs. Topical application for the lower intestinal tract can be effected in a rectal suppository formulation or in a suitable enema formulation. Topically-transdermal patches may also be used.
For topical applications, the pharmaceutical compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in at least one excipient. Excipients for topical administration of the compounds of this disclosure include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax, and water. Alternatively, pharmaceutical compositions disclosed herein can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in at least one pharmaceutically acceptable excipient. Suitable excipients include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol, and water.
The pharmaceutical compositions of this disclosure may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.
