Compounds that are histone deacetylase (HDAC) inhibitors have the potential to provide therapeutically effective pharmaceutical compositions that would be expected to have beneficial and improved pharmaceutical properties for the treatment of epigenetic related conditions or disorders such as cancer and other proliferative disorders.
Discussed herein is N-hydroxy-2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide and referred to herein as Compound 1. Compound 1 is also known as nanatinostat, VRx-3996, or CHR-3996. It has been previously described in patents and patent applications, e.g. U.S. Pat. No. 7,932,246 and U.S. patent application Ser. No. 15/959,482, each of which is incorporated by reference in their entirety.
As a selective inhibitor of HDAC, Compound 1 is useful in the treatment of conditions in which HDAC has demonstrated a role in epigenetic regulation and pathology, such as cancer, immune disorders and inflammation. Two critical aspects in the development of Compound 1 as a useful therapy for such diseases and disorders are the discovery of practical methods for the preparation of Compound 1, and the discovery of pharmaceutically acceptable forms of Compound 1 and pharmaceutical compositions comprising said forms.
As used herein, the term “crystalline,” “highly crystalline,” “crystalline solid form,” or “highly crystalline solid form” refers to a solid form which is substantially free of any amorphous solid state form. In some embodiments, the crystalline solid form is a single solid state form, e.g. crystalline mesylate Form 1 salt. One embodiment provides a composition wherein substantially free means less than about 10% (w/w), less than about 9% (w/w), less than about 8% (w/w), less than about 7% (w/w), less than about 6% (w/w), less than about 5% (w/w), less than about 4.75% (w/w), less than about 4.5% (w/w), less than about 4.25% (w/w), less than about 4% (w/w), less than about 3.75% (w/w), less than about 3.5% (w/w), less than about 3.25% (w/w), less than about 3% (w/w), less than about 2.75% (w/w), less than about 2.5% (w/w), less than about 2.25% (w/w), less than about 2% (w/w), less than about 1.75% (w/w), less than about 1.5% (w/w), less than about 1.25% (w/w), less than about 1% (w/w), less than about 0.9% (w/w), less than about 0.8% (w/w), less than about 0.7% (w/w), less than about 0.6% (w/w), less than about 0.5% (w/w), less than about 0.4% (w/w), less than about 0.3% (w/w), less than about 0.25% (w/w), less than about 0.20% (w/w), less than about 0.15% (w/w), less than about 0.1% (w/w), less than about 0.08% (w/w), or less than about 0.05% (w/w).

As used herein, the term “partially crystalline” or “partially crystalline material” refers to an ad-mixture of two or more solid state forms. In some embodiments, partially crystalline refers to an ad-mixture of an amorphous solid form and at least one crystalline solid form. Partially crystalline material is not amorphous.
In some embodiments, crystallinity of a solid form is determined by X-Ray Powder Diffraction (XRPD). In some embodiments, crystallinity of a solid form is determined by solid state NMR.
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.
As used in the specification and claims, the singular form “a”, “an” and “the” includes plural references unless the context clearly dictates otherwise.
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.
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.
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.
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.
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.
In one embodiment, the present invention provides solid state forms of the mesylate salt of N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide. 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 20 (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.
Both crystalline and amorphous solid state forms were identified for the mesylate salt of N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide. Amorphous solid state forms as described herein are specifically denoted as such.
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 2Θ allow appropriate error margins. Typically, the error margins are represented by “±”. For example, the degree 2Θ 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.
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 Celsius (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.
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.

N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide (500 mg) was weighed into a 20 ml vial and 35 vols (17.5 ml) of a selected solvent EtOH/water (9:1 v/v) was added. All samples appeared as suspensions and were stirred (500 rpm) at 50° C. Methanesulfonic acid (1.1 mole equivalent, 1.395 ml) was added as a 1 M stock solution in THF. The samples were all stirred for 1 hour at 50° C. before being cooled to 5° C. at 0.1° C./min. The samples were left to stir overnight at 5° C. Observations were made immediately after the salt addition and again once the solutions had cooled to 5° C.
N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide (100 g) was weighed into a 5 L flask and 1.5 L of ACN or EtOH was added. All samples appeared as suspensions and were stirred at 50° C. A 1.0 mole equivalent of methanesulfonic acid was added. The samples were all stirred for 1 hour at 50° C. before being cooled to 5° C. The samples were left to stir overnight at 5° C. The precipitated solid was collected by filtration to afford the crystalline mesylate Form 1 of N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide at 85% yield.
Mesylate Form 1 was successfully scaled up and XRPD confirmed good crystallinity and the material was characterized, the results of which are shown in Table 5 below.
1H-NMR
The API acid stoichiometry was determined as 1:1 by 1H-NMR and 0.01 mole eq. EtOH was identified. The retention of the parent structure was also confirmed by NMR following salt formation. The material was isolated in good purity at 99.5% by HPLC. The crystal habit for the mesylate salt was defined as small crystalline rods which were ca. 20-50 μm in size.
There were no thermal events observed in the TGA thermogram until the onset of decomposition from ca. 220° C. The DSC was characterized by a single exothermic event with an onset temperature at 222.1° C. (433 J/g) associated with the decomposition event by TGA.
Mesylate Form 1 appeared to be stable under variable humidity environments. The material was slightly hygroscopic by GVS with ˜0.35% reversible water uptake between 0-90% RH and the residue on recovery showed no change by XRPD. Mesylate Form 1 was unchanged by XRPD after 7 days at 25° C./97% RH and 40° C./75% RH and no significant drop in purity was noted.
Mesylate Form 1 is a crystalline non-solvated mesylate mono-salt that is a slightly hygroscopic and displayed stability up to 7 days under static stability conditions (25° C./97% RH, 40° C./75% RH).
The peak table and XRPD for Mesylate Form 1 can be found below (Table 6,
Aqueous solubility was determined by suspending sufficient compound in 0.5 ml deionized water to give a maximum final concentration of 40 mg/mi of the parent free-form of the compound. The suspension was equilibrated at 25° C., on a Heidolph plate shaker set to 750 rpm for 24 hours. After equilibration, the appearance was noted and the pH of the saturated solution was measured. Samples forming suspensions were centrifuged for 4 min at 13,500 rpm. Samples were then filtered through a glass fiber C filter (particle retention 1.2 μm), before dilution with H2O as appropriate.
Quantitation was by HPLC (see Table 2 for parameters) with reference to a standard solution of approximately 0.15 mg/ml in DMSO. Different volumes of the standard, diluted and undiluted sample solutions were injected. The solubility was calculated using the peak areas determined by integration of the peak found at the same retention time as the principal peak in the standard injection. Analysis was performed on an Agilent HP5100/Infinity 111260 series system equipped with a diode array detector and using OpenLAB software.
Thermodynamic aqueous solubility of mesylate and free base forms are significantly different, as shown in Table 8. Free base is essentially insoluble in water. The mesylate shows excellent solubility at 40 mg/mL and the final pH of saturated solution was ˜3.2.
The intrinsic dissolution rates (TDR) for the Mesylate Form 1 salt was determined in Fasted State Simulated Gastric Fluid FaSSGF media and compared with both Free Form A and Free Form B of N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide. The IDR were not determined in Fasted State Simulated Intestinal Fluid (FaSSIF) or Fed State Simulated Intestinal Fluid (FeSSIF) media after a low absorbance values were noted for the parent free form compound that did not allow for complete data analysis. The Mesylate Form 1 salt exhibited a high IDR with an intrinsic dissolution rate of 9.1 mg/min/cm2 (ca 8 times of free base form A) and the majority of the disc disintegrated in this media.
Crystalline mesylate Form 1 salt of N-hydroxy 2-{6-[(6-fluoro-quinolin-2-ylmethyl)-amino]-3-aza-bicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide (10 mg) was weighed into 4 HPLC vials. The relevant solvent (200 μl, 20 volumes) was added and the samples mixed on a vortex mixer to aid dissolution, observations were then made. If a clear, transparent solution was obtained, the solution was filtered using a 0.45 m PTFE membrane Acrodisc filter to remove any remaining solid particles. The solutions were then flash-frozen in an acetone/dry ice bath, and placed on the freeze dryer overnight. The next day, samples were removed from the freeze dryer, and analyzed by XRPD to confirm the amorphous solid state. The sample was further analyzed by mDSC and 1H NMR to determine residual solvent content and identify the glass transition of the amorphous solid. The results can be found in Table 9. The NMR identified 0.07 mol. eq. residual THF and the modulated DSC identified a high glass transition temperature, Tg=126.7° C. The purity was not significantly impacted by the lyophilization process and the amorphous showed moderate stability up to 7 days at 25° C./97% RH and 40° C./75% RH with appearing largely amorphous with a small reflection appearing at 3.7° 2θ.
1H-NMR
Mesylate Form 1 (400 mg) was placed in a 100 ml round-bottomed flask. To it was added THF/water (9:1 v/v) (28 ml, 70 volumes) and the sample was stirred at 50° C. The sample was partially soluble, and the temperature increased to 60° C. A white precipitate was observed, the amount of which seemed to increase with increased temperature/further dissolution of the initial solid. An aliquot was taken of the suspension, placed on a flat XRPD holder, and allowed to dry, to leave behind a thin residue. This was then analyzed by XRPD and found to be amorphous.
The sample was then heated to 70° C., where the solution remained turbid. The suspension was cooled again to 60° C., where an additional 1 ml was added, followed by further 1 ml aliquots added until an additional 9 ml had been added (total solvent: 38 ml, 95 volumes). The solution remained turbid and the temperature was again increased to 70° C., where a clear, colorless solution was obtained. The solution was cooled to 5° C. at 0.1° C./minute with stirring overnight.
The next morning, a thin suspension was observed. A small aliquot was taken and allowed to dry on a flat XRPD holder. The sample was observed to dry to a glass-like appearance, the solid was collected and flattened for analysis by XRPD. The sample appeared amorphous, with low-level crystalline peaks. The sample was stirred at 5° C. for a further two days, after which another aliquot was taken, and allowed to dry on a flat XRPD holder. The sample was isolated on a Buchner funnel with drying for ˜5 minutes to afford Mesylate Form 2.
1H-NMR
The 1H NMR was consistent with the structure, containing ˜0.9 mol. eq. mesylate, and there was low residual THF (0.008 mol. eq.). The IC analysis confirmed 0.9 mol. eq. Mesylate to be present. There was a 3.7% mass loss ambient—170° C. by TGA which was confirmed as water where KF identified 3.6% water (equating to 1 mol. Eq. water). The DSC thermogram showed a broad endotherm with onset at 124.7° C., which overlapped with the water loss, and was followed by two small exotherms with onsets at 155.4° C. and 171.4° C. From GVS analysis, Mesylate Form 2 was slightly hygroscopic, with ˜0.4% reversible water uptake between 0-90% RH and the hydrate appears to be relatively stable as the 1 mol. eq. of bound water was not lost during the desorption cycles. This was supported by the XRPD post-GVS being unchanged as Mesylate Form 2 to remain. After storage at 25° C./97% RH and 40° C./75% RH) for 1 week the form was unchanged by XRPD with no significant drop in HPLC purity noted. Analysis of particle size and morphology by microscopy showed the presence of agglomerates of ˜200 μm in size, comprised of primary irregular-shaped particles (≤10 μm) in size. HPLC showed a purity of 99.5%. In summary Mesylate Form 2 is a crystalline monohydrate mono-mesylate salt that is slightly hygroscopic.
The peak table for Mesylate Form 2 and XRPD for the sample can be found below (Table 11,
Mesylate Form 1 was dissolved in H2O (15 ml, ˜20 volumes) in a 20 ml scintillation vial at 50° C. to produce a clear, transparent solution. Undissolved particulates were observed (possible fibers from filter paper), and so the solution was filtered through an acrodisc filter (0.45 μm pore size). The sample was cooled to 5° C. at 0.1° C./minute and stirred at 5° C. overnight. The next day, the sample was observed to be a clear, transparent yellow solution, which turned turbid throughout the day. The next day, a peachy-colored thick suspension was observed. A small aliquot of the suspension was taken and analyzed by XRPD. The sample was isolated over gentle vacuum to remove excess water. The wet filter cake was air dried only. A small amount of the damp solid was then taken, which dried slightly on the holder prior to analysis by XRPD (indicated by color change from darker to lighter). The XRPD holder containing the aliquot taken from the suspension was re-analyzed after drying in air for ˜2 hours.
Analysis of the aliquot taken from the suspension after being left to stir overnight showed it to be Mesylate Form 3, however, after leaving it to dry for ˜2 hour on the XRPD holder it was shown to have become poorly crystalline. This behavior suggested that Mesylate Form 3 was likely to be a metastable hydrate. Identifying that excessive drying reduced the crystallinity resulted in the gentle isolation and air dying only of the bulk sample which successfully provided crystalline Mesylate Form 3 as summarized in Table 12.
1H-NMR
Mesylate Form 3 was isolated in good crystallinity and there was a drop in purity to 96.5%. The 1H NMR remained consistent with the structure and 1 mol. eq. mesylate identified present. IC analysis confirmed there to be 0.9 Mol. eq. mesylate (assuming 9 water molecules in the mass calculation. The TGA thermogram had a 28.8% mass loss ambient to 135° C. This was suspected to be bound water and potentially some residual surface water from the gentle sample drying. The Karl Fisher confirmed water was present with 46.6% water content. It is plausible the difference with respect to the TGA was due to the time difference between the analyses which could have resulted in the sample drying to a more stable level of water content. The DSC thermogram was complex displaying a broad endotherm with onset at 48.2° C. followed by a modulating baseline that was likely due to other thermal behavior. This was followed by sharp endotherm with an onset at 113.0° C.
The GVS analysis was critical in determining the nature of Mesylate Form 3. At the start of the GVS experiment at 40% RH the kinetic plot shows a loss of water mass until it stabilizes at 25.1% water content. Nine water molecules were calculated to be 23.5% w/w. the first sorption cycle from 40%-90% RH shows that 2% water uptake from the atmosphere occurs. The desorption cycle then loses incremental water down to 30% RH (to 24.30% water, close to ideal 9 mol. eq. water). The further drop in humidity to 20% RH is where the majority of this water is then lost which then further drops to down to 0% RH. The second sorption profile is different with ˜12% water uptake observed between 0-90% RH which is lost on the desorption cycle. The final sorption cycle up to 40% RH looks similar to sorption cycle 2 and suggests a hysteresis between 0-60% RH. The XRPD post-GVS was poorly crystalline with broad reflections that didn't match well with any of the known hydrates and has some reflection in common which may match Mesylate Form 1. From the combination of TGA, KF and GVS data Mesylate Form 3 is assigned as a nonahydrate (nine water molecules).
Mesylate Form 3 remained unchanged by XRPD when placed under static storage for 1 week at 25° C./97% RH showed conversion to Mesylate Form 5 at 40° C./75% RH again indicating some metastability to the form.
In summary, Mesylate Form 3 is assigned as a metastable nonahydrate of the mono-mesylate salt. The metastable nature of the form has been displayed through the drying processes on isolation, the different sorption profiles observed between the first and second cycle of the GVS (and post-GVS XRPD) and its conversion to the sesquihydrate Mesylate Form 5 after storage at 40° C./75% RH.
The peak table and XRPD for Mesylate Form 3 can be found below (Table 12,
The amorphous mesylate salt was generated using lyophilization as described in Example 3. The amorphous solid (750 mg) was suspended in THF/water (9:1 v/v) (15 ml, 20 volumes) and stirred at 5° C. producing a white suspension. The suspension was stirred overnight at 5° C. and the next morning, an aliquot was taken, placed on a flat XRPD holder and analyzed by XRPD. The suspension was then isolated over a Buchner funnel and dried for ˜15 minutes under vacuum. The solid was re-analyzed by XRPD post-isolation and drying.
1H-NMR
The sample was isolated in good crystallinity with high purity at 99.3% by HPLC. The 1H NMR confirmed there to be at least 0.9 mol. eq. mesylate and the 1H-NMR spectrum was consistent with the structure. The TGA had a mass loss of 9.6% ambient to 92° C. which was suspected to be water die to the absence of residual THF. KF analysis showed 12.6% water (equating to ˜ 4 mol. eq. water). The DSC displayed overlapping endothermic events with an onset at 51.0° C. and overlapped with the water loss event by TGA.
The GVS analysis showed different behaviors between cycle 1 and cycle 2. The starting water content at 40% RH was 9.4% water with an additional 0.7% water uptake in the first sorption cycle (40-90% RH). During the desorption cycle there was gradual water loss (0.8% water) down to 20% RH with a significant loss (˜9% water content) between 20 to 10% RH. During the second cycle, a total water uptake of 3.6% is observed between 0-90% RH, with hysteresis observed between the sorption/desorption steps. The GVS data was in closer agreement to the TGA loss than the KF and the assessment was made that Mesylate Form 4 contained 3 mol. eq. water. The discrepancy with the KF may have been due to differences in sampling time when the sample may have had additional residual water from the initial isolation. The XRPD post-GVS showed conversion to Mesylate Form 1.
Mesylate Form 4 was unchanged by XRPD after static storage at 40° C./75% RH for 1 week with good purity of 99.4%. By contrast conversion to Mesylate Form 1 after storage at 25° C./97% RH was observed and retained a good purity of 99.5%. The microscopy analysis showed the presence of large agglomerates ˜600 μm in size, comprised of smaller lath-type particles ˜30 μm in size. Finer particles of 5-10 μm in size were also observed.
In summary, Mesylate Form 4 is a metastable trihydrate of the mono-mesylate salt as supported by the GVS and TGA analysis. Evidence of limited stability were displayed by conversion to Mesylate Form 1 post GVS analysis and after storage at 25° C./97% RH.
The peak table and XRPD for Mesylate Form 4 can be found below (Table 14,
Mesylate Form 5 was obtained during an attempted preparation of Mesylate Form 2, from a solution in THF/water (9:1 v/v). Mesylate Form 5 was also observed when Mesylate Form 3 was held at 40° C./75% RH for 1 week. The characterization of mesylate Form 5 is shown below.
1H-NMR
The 1H NMR was consistent with the structure with ˜0.9 mol. eq. mesylate present and no residual THE signal was detected. The sample was recovered in good purity at 99.4% by HPLC. The TGA thermogram had a two-step mass loss of 5.9% which was suspected to be water. Karl Fisher analysis confirmed there to be 5.6% water content (equating to 1.6 mol. eq. water). The DSC had a small endotherm with an onset at 28.4° C. followed by a broad endotherm with onset at 56.8° C. These two endotherms overlapped well with the two-step mass loss. These were followed by an endotherm with onset at 152.3° C. and a subsequent exotherm with onset at 163.3° C. The GVS analysis indicated Mesylate Form 5 to be hygroscopic with 4.7% reversible water uptake from 0-90% RH. From the GVS isotherm and kinetic plots it appears that the form is quite stable with no indication the bound water was lost. This was corroborated with the XRPD post-GVS analysis which was unchanged as Mesylate Form 5. The microscopy analysis shows the presence of agglomerates ˜100 μm in size, comprised of irregular particles and laths, with a primary particle size≤10 μm. When placed under static storage conditions for 1 week, Mesylate Form 5 was unchanged by XRPD at both 25° C./97% RH and 40° C./75% RH.
In summary, Mesylate Form 5 has been identified as a stable sesquihydrate (q.5 mol. eq. water) of the mono-mesylate salt that is hygroscopic, as determined by GVS. The form showed short-term solid form stability, remaining unchanged by XRPD after GVS and static storage at elevated conditions up to 1 week.
The peak table and XRPD for Mesylate Form 5 can be found below (Table 16,
Mesylate Form 6 was obtained from cooling a turbid solution in DMF to 5° C. The characterization data is summarized in Table 17. The 1H NMR showed 0.7 mol. eq. DMF ˜0.8 mol. eq. mesylate present in the solid. The TGA had 9.0% mass loss that matched the DMF content by NMR. A small endotherm was observed with onset at 51.1° C. by DSC, followed by a broad endotherm at 84.7° C., which corresponded to the mass loss observed by TGA. An additional, smaller endotherm was observed at 124.7° C. The form converted to Mesylate Form 1 after 1 week at both 40° C./75% RH and 25° C./97% RH. Mesylate Form 6 was tentatively assigned as a DMF solvate that can desolvate under certain conditions.
1H-NMR
The peak table for Mesylate Form 6 and XRPD for the sample can be found below (Table 18,
Mesylate Form 7 was obtained from cooling a solution in NMP to 5° C. The characterization of Mesylate Form 7 is shown in Table 19. 1H NMR analysis showed 1 mol. eq. NMP and a lower 0.7 mol. eq. mesylate present. Due to insufficient sample remaining, thermal analysis was not possible. Mesylate Form 7 converted to Mesylate Form 1 after 1 week storage at 40° C./75% RH and 25° C./97% RH. Mesylate Form 7 was tentatively assigned as an NMP solvate.
1H-NMR
The peak table for Mesylate Form 7 and XRPD for the sample can be found below (Table 20,
Mesylate Form 8 was obtained following maturation temperature cycling (RT/50° C.) of the amorphous salt in DMF. The characterization results are shown in Table 21. The 1H NMR analysis showed approximately 0.9 mol. eq. DMF ad ˜0.9 mol. eq. mesylate. The TGA had a 12.2% mass loss 98-134° C. that was in close agreement with the DMF content. The DSC showed an overlapping broad and a sharp endotherm, the latter with onset at 98.8° C. After static storage of the form converted to Mesylate Form 1 after 1 week at 40° C./75% RH and 25° C./97% RH. Mesylate Form 8 was tentatively assigned as another DMF solvate.
1H-NMR
The peak table for Mesylate Form 8 and XRPD for the sample can be found below (Table 22,
Mesylate Form 1 was dissolved in DMSO/acetone (1:1 v/v) (35 ml, 35 volumes) at 50° C. with stirring to produce a clear, yellow solution. The sample was stirred for 1 hour further at 50° C. before cooling to 5° C. at 0.5° C./minute and was stirred at 5° C. overnight. The resulting white suspension was filtered over a Buchner funnel and dried for ca. 15 minutes. A small sample was taken and analyzed by XRPD. The solid was isolated in 57% yield, and was further characterized by 1H NMR, TGA, DSC and KF and stored under elevated static conditions.
XRPD confirmed the isolation of Mesylate Form 9. The 1H NMR showed the sample to contain 2.9 mol. eq. DMSO, with residual acetone also present (<0.01 mol. eq.). The TGA thermogram showed a large mass loss, of 41.2%, corresponding to 4.3 mol. eq. DMSO. Karl Fisher indicated there was 4.8% water content. The higher DMSO content in this sample in addition to water content may be due to insufficient drying of the sample at scale. The DSC thermogram had a broad endotherm at 78.2° C. (which may have possible overlapping events), overlapped with the mass loss observed by TGA. Mesylate Form 9 converted under storage at both 40° C./75% RH and 25° C./97% RH to Mesylate Form 1, with the sample stored at 40° C./75%0 RH showing a color change to yellow. The analysis indicated to Mesylate Form 9 being a DMSO solvate and with a more appropriate drying protocol, the DMSO content is likely lower similar to the screening sample.

The polymorph studies of the mesylate salts of compound 1 yielded 10 forms: an amorphous form, an anhydrate (Form 1) 4 hydrates (Forms 2-5), 2 DMF solvates (Forms 6 and 8), an NMP solvate (Form 7), and a DMSO solvate (Form 9). The solvates were unstable, converting to Form 1 at 25° C./97% RH and 40° C./75% RH.
Form 2 was characterizes as a monohydrate, a slightly hygroscopic form that was stable after 1 week at elevated conditions. A metastable nonahydrate (Form 3) was identified and was unstable to drying (losing significant crystallinity) and would convert to Mesylate Form 5 at 40° C./75% RH (and remained as Mesylate Form 3 at 25° C./97% RH). Mesylate Form 4 was a metastable trihydrate that converted to Mesylate Form 1 at 25° C./97% RH and was a mixture of Mesylate Form 1 and Form 4 after 1 week at 40° C./75% RH. A fourth hydrate was then identified and isolated during an initial attempt to prepare the monohydrate. This new hydrate, Mesylate Form 5 was a hygroscopic sesquihydrate that was stable after GVS analysis and remained as Mesylate Form 5 after 1 week at the elevated temperature/humidity conditions.
The thermodynamic solubility of the anhydrous Mesylate Form 1 and four hydrates was measured in FaSSIF, FeSSIF and FaSSGF media. The anhydrous Form 1 typically displayed the highest solubility (1.90 mg/ml—FaSSIF; 0.34—FeSSIF; 21.0 mg/ml FaSSGF) of the forms except Form 4 (trihydrate) which had slightly higher solubility in FaSSGF (24.0 mg/ml). The solubility residues in most cases showed disproportionation of the salt to FreeForm A, although two new solubility residue patterns were identified in FaSSGF from Mesylate Form 3 and Form 5, respectively. There was insufficient residue to characterize these further.
Competitive slurries of the anhydrous and hydrated forms in different water activity at 50° C. and 5° C. were used to determine the thermodynamic stability relationships. Mesylate Form 1 was the most stable up to aw=0.6 at 50° C. and up to at least aw=0.3 at 5° C. Based on the solid form properties, thermodynamic aqueous solubility and understanding of the thermodynamic stability relationships between these forms it was recommended to proceed to initial crystallization development of the anhydrous Mesylate Form 1.
