BACKGROUND OF THE INVENTION [0002] RAF kinase functions in the Ras-Raf-MEK-ERK mitogen activated protein kinase (MAPK) pathway (also known as MAPK/ERK pathway) by phosphorylating and activating MEK. By altering the levels and activities of transcription factors, MAPK leads to altered transcription of genes that are important for the cell cycle. Deregulation of MAPK activity occurs frequently in tumors. Accordingly, therapies that target RAF kinase activity are desired for use in the treatment of cancer and other disorders characterized by aberrant MAPK/ERK pathway signaling. One such modulator of RAF kinase is (S)-N-(3-(2-(((R)-1-hydroxypropan-2- yl)amino)-6-morpholinopyridin-4-yl)-4-methylphenyl)-3-(2,2,2 -trifluoroethyl)pyrrolidine-1- carboxamide and pharmaceutically acceptable salts thereof.

Definitions

[0028] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs.

All patents and publications referred to herein are incorporated by reference.

[0029] As used in the specification and claims, the singular form “a”, “an” and “the” includes plural references unless the context clearly dictates otherwise.

[0030] The term “hydrate” and “solvate” are meant to describe crystalline Compound 1 forms that include an amount of water or solvent, as supported by data derived from differential scanning calorimetry (DSC) experiments, thermogravimetric analysis (TGA) experiments, X-ray diffraction experiments, and/or the procedure for generating the solid crystalline form. In some embodiments, a solvate crystalline form or hydrate crystalline form comprises at least 1.5%, 1.75%, 2.0%, 2.5%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0%, 8.0%, 9.0%, 10.0%, 15.0%, or 20.0% of the total weight of the sample as water, solvent, or a combination thereof, as determined by TGA. In some embodiments, a solvate crystalline form or hydrate crystalline form exhibits at least one DSC endotherm onset before or within 30 °C of the boiling point of water or the solvent(s) used in the generation of the crystalline form. For example, a hydrate crystalline form may have a DSC endotherm onset at 108 °C, with the endotherm peak positioned at 124 °C.

[0031] Crystalline solid forms termed a “solvate,” or “hydrate” are not meant to be limiting. For example, a solvate or hydrate can comprise a combination of water and solvent in the crystalline solid form.

[0032] The term “type,” “form,” and “pattern” are meant to be used interchangeably and are meant to refer to a particular crystalline material with properties described herein. For example, “crystalline hydrate Type A,” “crystalline hydrate Form A,” and “XRPD Pattern A” refer to the same crystalline matter.

[0033] The term "about" when referring to a number or a numerical range means that the number or numerical range referred to is an approximation within experimental variability (or within statistical experimental error), and thus the number or numerical range, in some instances, will vary between 1% and 15% of the stated number or numerical range.

[0034] The term "substantially similar" as used herein means an analytical spectrum, such as XRPD pattern, DSC thermogram, or TGA thermogram, which resembles the reference spectrum to a great degree in both the peak locations and peak intensity.

Characterization of Compounds and Solid State Forms

[0035] In one embodiment, the present invention provides solid state forms of Compound 1, Compound 2, Compound 3, Compound 4, Compound 5, and Compound 6. In one embodiment, the crystalline forms are characterized by the interlattice plane intervals determined by a X-ray powder diffraction (XRPD) diffractogram. The diffractogram is typically represented by a diagram plotting the intensity of the peaks versus the location of the peaks, i.e., diffraction angle 2Q (two-theta) in degrees. The characteristic peaks of a given compound can be selected according to the peak locations and their relative intensity to distinguish compounds and crystalline structures from others. Amorphous solid state forms were also characterized by XRPD. Amorphous solid state forms exhibit an absence of interlattice plane intervals.

[0036] Both crystalline and amorphous solid state forms were identified for Compound 2, Compound 4, Compound 5, and Compound 6. Amorphous solid state forms as described herein are specifically denoted as such. For example, the language “solid state form of Compound 2” is meant to describe a crystalline form of Compound 2 unless specified as an amorphous solid state form. [0037] Those skilled in the art recognize that the measurements of the XRD peak locations and/or intensity for a given crystalline form of the same compound will vary within a margin of error. The values of degree 2Q allow appropriate error margins. Typically, the error margins are represented by "±". For example, the degree 2Q of "8.716±0.3" denotes a range from 8.716+0.3, i.e., 9.016, to 8.716-0.3, i.e., 8.416. Depending on the sample preparation techniques, the calibration techniques applied to the instruments, human operational variation, and etc., those skilled in the art recognize that the margin of error for a XRD can be ±0.5; ±0.4; ±0.3; ±0.2;

±0.1; ±0.05; or less. Additional details of the methods and equipment used for the XRD analysis are described in the Examples section.

[0038] In one embodiment, the crystalline forms are characterized by Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). The DSC thermogram is typically expressed by a diagram plotting the normalized heat flow in units of Watts/gram ("W/g") versus the measured sample temperature in degree C. The DSC thermogram is generally evaluated for extrapolated onset and end (outset) temperatures, peak temperature, and heat of fusion. The single maximum value of a DSV thermogram is often used as the characteristic peak to distinguish one crystalline form from another crystalline form. The TGA thermogram is typically expressed by a diagram plotting the weight loss percentage (%) versus the measured sample temperature in degree C. In the figures disclosed herein, DSC and TGA thermograms have been plotted sharing an X axis (temperature), but have distinct Y axes of weight % and heat flow corresponding respectively to TGA and DSC measurements.

[0039] Those skilled in the art recognize that the measurements of the DSC and TGA thermograms for a given crystalline form of the same compound will vary within a margin of error. The values of a single maximum value, expressed in degree C, allow appropriate error margins. Typically, the error margins are represented by "±". For example, the single maximum value of "53.1 °C ±10.0" denotes a range from 53.1 °C + 10.0, i.e., 63.1 °C, to about 53.1 °C - 10.0, i.e., 43.1 °C. Depending on the sample preparation techniques, crystallization conditions, calibration techniques applied to the instruments, human operational variations, and etc., those skilled in the art recognize that the appropriate margin of error for a single maximum value can be ±10.0; ±7.5; ±5.0; ±2.5; ±2; ±1.5; ±1; ±0.5; or less for any of the powder diffraction reflections described herein.

[0040] Additional details of the methods and equipment used for the DSC and TGA thermogram analysis are described in the Examples section.

Amorphous (S)-N-(3-(2-(((R)-1- hydroxypropan-2-yl)amino)-6-morpholinopyridin-4-yl)-4-methyl phenyl)-3 -(2,2,2- trifluoroethyl)pyrrolidine-1 -carboxamide hydrochloride was formed by rapid evaporation of 15 mg of Compound 2 dissolved in 0.5 mL of methanol. The solid was confirmed to be amorphous by XRPD. Slurry of amorphous (S)-N-(3-(2-(((R)-1-hydroxypropan-2-yl)amino)-6- morpholinopyridin-4-yl)-4-methylphenyl)-3-(2,2,2-trifluoroet hyl)pyrrolidine-l -carboxamide hydrochloride in 0.5 mL of the solvents in Table 13 were prepared. Each suspension was stirred for one day at 50 °C and at RT. Each suspension was filtered and analyzed by XRPD. In each experiment, conversion from amorphous (S)-N-(3-(2-(((R)-1-hydroxypropan-2-yl)amino)-6- morpholinopyridin-4-yl)-4-methylphenyl)-3-(2,2,2-trifluoroet hyl)pyrrolidine-l -carboxamide hydrochloride to crystalline Compound 2 was observed.

[00107] Compound 1 and Compound 2 were evaluated for stability at 60 °C and 40 °C at 75 % relative humidity for 9 days. At 0, 3, and 9 days, the samples were dissolved with diluent to prepare a solution for purity analysis by UPLC. Solid samples were also analyzed by XRPD to check the crystal form. The results of the study are summarized below in Table 14.

Table 14. Summary of Stability Studies

[00108] A solution of Compound 2 was evaluated for stability in 0.5% MC/0.1% Tween 80 at 10 mg/mL. 10.7 mg of Compound 2 was weighed into a sample vial, and then 500 pL of 1% MC and 500 pL of 0.2% Tween 80 were added to obtain a suspension at 10 mg/mL (calculated as the free base). The mixture was kept stirring for 15 min at RT and the suspension was placed at RT for 7 days. No form change occurred, however purity decreased by 0.13% after 7 days as determined by UPLC.

[00109] Thermodynamic solubility of Compound 2 was measured in 13 solvents at RT and 50 °C by UPLC, respectively. The results are summarized in Table 15. Compound 2 showed the highest solubility in MeOH, at about 102 mg/mL at 50 °C and 55 mg/mL at RT. In most of other selected solvents, the compound was almost insoluble (< 0.5 mg/mL) except in EtOH and water where it was slightly soluble (6-9 mg/mL). The solid forms of the residual solids from solubility testing were examined by XRPD and no form change occurred during the solubility testing.

Table 15. Summary of Solubility Experiments [00110] Comparison dissolution trials were performed on Compounds 1 and 2. About 20 mg of each sample was weighed into a sample vial and then 4 mL of media was added to make a suspension. All suspensions were shaken at 37 °C with a rate of 200 rpm. At 0.5, 2 and 24 hours, each suspension was filtered, and the filtrate was analyzed by UPLC to test the solubility. He pH of the filtrate was measured, and the filter cake was analyzed by XRPD. Compound 1 has very low solubility in water (< 9 µg/mL), while Compound 2 exhibits a solubility in water of about 2.5 mg/mL. In biorelevant dissolution media FaSSIF and FeSSIF, the solubility of the Compound 1 and Compound 2 were similar. Compound 1 converted to Compound 2 in FaSSGF. The experimental results are summarized in Table 16. Table 13.

In MTBE, the reagents were stirred for 1 hour at 50 °C, after which solids appeared and were isolated by filtration to give crystalline Compound 4 Form I as shown in Figure 7. In acetone, the reagents were stirred for 2 hours, after which solids appeared and were isolated by filtration to give crystalline Compound 4 Form II as shown in Figure 8. An amorphous form of (S)-N-(3-(2-(((R)-1-hydroxypropan-2-yl)amino)-6-morpholinopy ridin-4-yl)- 4-methylphenyl)-3-(2,2,2-trifluoroethyl)pyrrolidine-1-carbox amide 4-methylbenzenesulfonate was obtained when performing the synthesis in ethyl acetate and evaporating the solvent, as determined by XRPD.

In acetonitrile, the reagents were combined and stirred resulting in the appearance of solids which were isolated by filtration to give crystalline Compound 6 Form I. In isopropyl alcohol, the reagents were combined and stirred resulting in the appearance of solids which were isolated by filtration to give crystalline Compound 6 Form II. An amorphous form of (S)-N-(3-(2-(((R)-1-hydroxypropan-2-yl)amino)-6- morpholinopyridin-4-yl)-4-methylphenyl)-3-(2,2,2-trifluoroet hyl)pyrrolidine-1-carboxamide sulfate was obtained when performing the reaction in acetone with 0.5 equivalents of sulfuric acid and evaporating the acetone, as determined by XRPD. Example 7: Drug Product Formulation and Manufacturing Process [00115] The formulation of the drug product provides an immediate release of Compound 2 over a period of approximately 1 hr. As the tablet is exposed to water and starts to disintegrate, drug substance is quickly released from the tablet core. The tablets are intended to dissolve completely in the stomach where the solubility is highest. In order to enable fast dissolution, a super-disintegrant such as croscarmellose sodium, is added to the formulation. Other components of the formulation include fillers such as microcrystalline cellulose, mannitol and hypromellose succinate acetate, anti-adherent such as talc, glidant such as silicon dioxide, and a lubricant such as sodium steryl fumarate. The tablets are film-coated using non-functional coatings containing polyvinyl alcohol, plasticizer such as PEG, titanium dioxide, and other coloring pigments. [00116] Figure 14 illustrates the manufacturing process used for an exemplary drug product. A dry granulation process was selected for the manufacture of tablets in order to improve blend flow in the tablet press and weight uniformity of the tablet core formulation. The tablet manufacturing process consists of first blending Compound 2, microcrystalline cellulose, mannitol, hypromellose succinate acetate, talc, croscarmellose sodium, and silicon dioxide in a blender. The blended material is passed through a Comil to breakup any aggregates, before adding sodium stearyl fumarate and blending further. The lubricated blend is dry granulated in a roller compactor to increase density of the material, followed by milling. To the granulated milled material, which represents about 97% of the formulation on a weight basis, are added croscarmellose sodium, silicon dioxide, and sodium stearyl fumarate. This mixture of granules and extra-granular excipients is blended to prepare the final composition for tableting. Tablet cores are compressed using a rotary tablet press. Different tablet strengths maybe created by adjusting tablet weights (e.g., 25 and 100 mg strength tablets). After compression, tablet cores are coated using an aqueous based film coating system in a pan coater.
