In the synthesis of a chemical compound intended for pharmaceutical use, it is necessary to isolate and purify the compound at the completion of the synthesis process and prior to further processing to provide the compound in a pharmaceutical formulation. The isolation and the purification steps, which can be combined or separate consecutive steps, provide the compound as a purified solid, ideally with minimal loss of yield during isolation of the compound from other components of the reaction mixture and/or during purification to remove impurities from the isolated compound sample.
It is desirable to provide a solid form of such a compound that can be reproducibly produced from the isolation and/or purification steps.
Further, it is desirable to isolate the compound in a solid form that is physically and chemically stable upon storage, including at different conditions of temperature and humidity. It is also desirable to provide a compound in a solid form that is amenable to additional processing, for example a crystalline form that can be converted to other solid forms, such as an amorphous form or other crystalline forms.
As described herein, crystalline forms of Compound (I) are surprisingly amenable to additional processing and can be converted to other solid forms. The present invention is directed to these and other important aspects.
The present invention provides crystalline forms Compound (I), namely Form F, Form G, Form H, Form I, Form J, and Form K. The name used herein to characterize a specific form, e.g. “Form F”, “Form G”, etc. should not be considered limiting with respect to any other substance possessing similar or identical physical and chemical characteristics, but rather it should be understood that this designation is a mere identifier that should be interpreted according to the characterization information also presented herein.
The features and advantages of the invention may be more readily understood by those of ordinary skill in the art upon reading the following detailed description. It is to be appreciated that certain features of the invention that are, for clarity reasons, described above and below in the context of separate embodiments, may also be combined to form a single embodiment. Conversely, various features of the invention that are, for brevity reasons, described in the context of a single embodiment, may also be combined so as to form sub-combinations thereof.
The names used herein to characterize a specific form, e.g., “Form F” etc., are merely identifiers that are to be interpreted in accordance with the characterization information presented herein (or in references cited herein) and are not to be limited so as to exclude any other substance possessing similar or identical physical and chemical characteristics.
The definitions set forth herein take precedence over definitions set forth in any patent, patent application, and/or patent application publication incorporated herein by reference.
All numbers expressing quantities of ingredients, weight percentages, temperatures, and so forth that are preceded by the word “about” are to be understood as only approximations so that slight variations above and below the stated number may be used to achieve substantially the same results as the stated number. Accordingly, unless indicated to the contrary, numerical parameters preceded by the word “about” are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
All measurements are subject to experimental error, consistent with the spirit of the invention.
As used herein, “polymorphs” refer to crystalline forms having the same chemical structure but different spatial arrangements of the molecules and/or ions forming the crystals.
As used herein, “hydrate” refers to having a stoichiometric or non-stoichiometric amount of water molecules incorporated into the crystalline lattice structure. In some embodiments, a stoichiometric amount may be specified (e.g., monohydrate).
As used herein, “amorphous” refers to a solid form of a molecule and/or ion that is not crystalline. An amorphous solid does not display a definitive X-ray diffraction pattern with sharp maxima.
As used herein, “substantially pure,” when used in reference to a crystalline form of a compound, means having the crystalline form at a purity greater than 90 weight %, including greater than 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99 weight %, and also including equal to about 100 weight %, based on the weight of the sample or specimen. The remaining material comprises other form(s) of the compound, and/or reaction impurities and/or processing impurities arising from its preparation. For example a crystalline form of Compound (I) may be deemed substantially pure in that it has a purity greater than 90 weight %, as measured by means that are at this time known and generally accepted in the art, where the remaining less than 10 weight % of material comprises amorphous and/or other form(s) of Compound (I) and/or reaction impurities and/or processing impurities.
As used herein, a powder X-ray diffraction (PXRD) pattern “comprising” a number of peaks selected from a specified group of peaks, is intended to include PXRD patterns having additional peaks that are not included in the specified group of peaks. For example, a PXRD pattern comprising four or more (or five or more, etc.) peaks or 2θ values selected from: a, b, c, d, e, f, g, and h, is intended to include a PXRD pattern having: (a) four or more (or five or more, etc.) 2θ values selected from: a, b, c, d, e, f, g, and h; and (b) zero, one, or more peaks that are not one of peaks a, b, c, d, e, f, g, and h.
The presence of reaction impurities and/or processing impurities may be determined by analytical techniques known in the art, such as, for example, chromatography, nuclear magnetic resonance spectroscopy, mass spectrometry, and/or infrared spectroscopy.
As used herein, the unit cell parameter “molecules per unit cell” refers to the number of molecules of Compound (I) in the unit cell.
Forms of Compound (I) have been described in WO 2018/183656 (Form A), WO 2019/232138 (Form B), WO 2020/251911 (Forms C and D), and U.S. Provisional Patent Application No. 63/143,769 (Form E).

Crystalline forms may be prepared by a variety of methods, including for example, crystallization or recrystallization from a suitable solvent, sublimation, growth from a melt, solid state transformation from another phase, crystallization from a supercritical fluid, and jet spraying. Techniques for crystallization or recrystallization of crystalline forms from a solvent mixture include, for example, evaporation of the solvent, decreasing the temperature of the solvent mixture, crystal seeding a supersaturated solvent mixture of the molecule and/or salt, freeze drying the solvent mixture, and addition of antisolvents (countersolvents) to the solvent mixture. High throughput crystallization techniques may be employed to prepare crystalline forms including polymorphs.
Crystals of drugs, including polymorphs, methods of preparation, and characterization of drug crystals are discussed in Solid-State Chemistry of Drugs, S. R. Byrn, R. R. Pfeiffer, and J. G. Stowell, 2nd Edition, SSCI, West Lafayette, Indiana (1999).
For crystallization techniques that employ solvent, the choice of solvent or solvents typically depends on one or more factors, such as solubility of the compound, crystallization technique, and vapor pressure of the solvent. Combinations of solvents may be employed, for example, the compound may be solubilized into a first solvent to afford a solution, followed by the addition of an antisolvent to decrease the solubility of the compound in the solution and to afford the formation of crystals. An antisolvent is a solvent in which the compound has low solubility.
In one method to prepare crystals, a compound is suspended and/or stirred in a suitable solvent to afford a slurry, which may be heated to promote dissolution. The term “slurry”, as used herein, means a saturated solution of the compound, which may also contain an additional amount of the compound to afford a heterogeneous mixture of the compound and a solvent at a given temperature.
Seed crystals may be added to any crystallization mixture to promote crystallization. Seeding may be employed to control growth of a particular polymorph or to control the particle size distribution of the crystalline product. Accordingly, calculation of the amount of seeds needed depends on the size of the seed available and the desired size of an average product particle as described, for example, in “Programmed Cooling of Batch Crystallizers,” J. W. Mullin and J. Nyvlt, Chemical Engineering Science, 1971,26, 369-377. In general, seeds of small size are needed to effectively control the growth of crystals in the batch. Seeds of small size may be generated by sieving, milling, or micronizing of large crystals, or by micro-crystallization of solutions. Care should be taken that milling or micronizing of crystals does not result in any change in crystallinity from the desired crystal form (i.e., a change to amorphous or to another polymorph).
A cooled crystallization mixture may be filtered under vacuum, and the isolated solids may be washed with a suitable solvent, such as cold recrystallization solvent, and dried under a nitrogen purge to afford the desired crystalline form. The isolated solids may be analyzed by one or more suitable spectroscopic or analytical techniques, such as solid state nuclear magnetic resonance, differential scanning calorimetry, X-ray powder diffraction, or the like, to assess formation of the preferred crystalline form of the product. The resulting crystalline form is typically produced in an amount of greater than about 70 weight % isolated yield, preferably greater than 90 weight % isolated yield, based on the weight of the compound originally employed in the crystallization procedure. The product may be co-milled or passed through a mesh screen to delump the product, if necessary.
Crystalline forms may be prepared directly from the reaction medium of the final process for preparing Compound (I). Such preparation may be achieved, for example, by employing in the final process step a solvent or a mixture of solvents from which Compound (I) may be crystallized. Alternatively, crystalline forms may be obtained by distillation or solvent addition techniques. Suitable solvents for this purpose include, for example, the aforementioned nonpolar solvents and polar solvents, including protic polar solvents such as alcohols, and aprotic polar solvents such as ketones.
The presence of more than one polymorph in a sample may be determined by techniques such as powder X-ray diffraction (PXRD) or solid state nuclear magnetic resonance spectroscopy (ssNMR). For example, the presence of extra peaks in the comparison of an experimentally measured PXRD pattern with a simulated PXRD pattern may indicate the presence of more than one polymorph in the sample. The simulated PXRD may be calculated from single crystal X-ray data. See Smith, D. K., “A FORTRAN Program for Calculating X-Ray Powder Diffraction Patterns,” Lawrence Radiation Laboratory, Livermore, California, UCRL-7196 (April 1963).
Form E of Compound (I) may be characterized using various techniques, the operation of which are well known to those of ordinary skill in the art. Form E may be characterized and distinguished using single crystal X-ray diffraction, which is based on unit cell measurements of a single crystal at a fixed analytical temperature. A detailed description of unit cells is provided in Stout & Jensen, X-Ray Structure Determination: A Practical Guide, Macmillan Co., New York (1968), Chapter 3, which is herein incorporated by reference. Alternatively, the unique arrangement of atoms in spatial relation within the crystalline lattice may be characterized according to the observed fractional atomic coordinates. Another means of characterizing the crystalline structure is by powder X-ray diffraction analysis in which the diffraction profile is compared to a simulated profile representing pure powder material, both run at the same analytical temperature, and measurements for the subject form are characterized as a series of 2θ values (e.g., two, three, four or more).
Other methods of characterizing the form may be used. Such methods include solid state nuclear magnetic resonance (ssNMR), differential scanning calorimetry (DSC), thermography, and gross examination of the crystalline or amorphous morphology. Two or more of these parameters may also be used in combination to characterize the subject form.
The crystalline forms of Compound (I) described herein can be used to isolate Compound (I) from other components at the completion of the synthesis process; and/or to purify Compound (I) by one or a series of crystallization steps. The isolation and the purification steps can be combined or practiced as separate process steps. Each of the crystalline forms described herein can also be used to make other solid forms of Compound (I), including, for example, Form A (which is described in WO 2018/183656), one or more of the other forms described herein, and/or amorphous Compound (I). For example, in certain embodiments, a method of preparing amorphous Compound (I) comprises preparing crystalline Form F, wherein crystalline Form F is characterized as described herein. In further embodiments, amorphous Compound (I) is then used to make a dosage form (e.g., a dosage form comprising a solid dispersion of amorphous Compound (I)) for clinical use.
Each of the crystalline forms of Compound (I) described herein may be used alone or in combination with other forms of Compound (I) (including the other crystalline forms described herein), and/or formulated with one or more excipients or other active pharmaceutical ingredients to make pharmaceutical compositions.

Single crystal X-ray data of Form F of Compound (I) were collected using a Bruker X8 Kappa diffractometer equipped with APEX II CCD detector and Microstar Rotating Anode X-ray source of monochromatic Cu Kα radiation.
Indexing and processing of the measured intensity data were carried out with the APEX2 program suite (Bruker AXS, Inc., 5465 East Cheryl Parkway, Madison, WI 53711 USA).

Structure refinements involved minimization of the function defined by Σw(|Fo|−|Fc|)2, where w is an appropriate weighting factor based on errors in the observed intensities, Fo is the structure factor based on measured reflections, and Fc is the structure factor based on calculated reflections. Agreement between the refined crystal structure model and the experimental X-ray diffraction data was assessed by using the residual factors R=Σ∥Fo|−|Fc∥/Σ|Fo| and wR=[Σw(|Fo|−|Fc|)2/Σw|Fo|]1/2.

An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640e) was analyzed to verify the Si 111 peak position. A specimen of the sample was sandwiched between 3 μm thick films and analyzed in transmission geometry. A beam-stop and short antiscatter extension were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v.5.5.
Differential scanning calorimetry (DSC) was performed using a Mettler-Toledo DSC3+ differential scanning calorimeter. A tau lag adjustment was performed with indium, tin, and zinc. The temperature and enthalpy were adjusted with octane, phenyl salicylate, indium, tin, and zinc. The adjustment was then verified with octane, phenyl salicylate, indium, tin, and zinc. The sample was placed into a hermetically sealed aluminum DSC pan, and the weight was accurately recorded. The pan lid was pierced then inserted into the DSC cell. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. Data was collected from −20° C. to 350° C. or room temperature to 350° C. at a heating rate of 10° C./min.
Thermal gravimetric analysis (TGA) was performed using a Mettler-Toledo TGA/DSC3+ analyzer. Temperature calibration was performed using calcium oxalate, indium, tin, and zinc. The sample was placed in an aluminum pan. The sample was sealed, the lid was pierced, and the sample was then inserted into the TG furnace. The furnace was heated under nitrogen with flow of 50 mg/mL. The method included heating from ambient temperature to 350° C. at a heating rate of 10° C./min.
