TECHNICAL FIELD [0002] The present disclosure is directed to solid forms, dispersions and pharmaceutical compositions of a pyruvate kinase R (PKR) activating compound. More specifically, the present disclosure is directed to crystalline solid forms, spray-dried dispersions and pharmaceutical compositions of (S)-1-(5-[2H,3H-[1,4]dioxino[2,3-b]pyridine-7-sulfonyl]-1H,2H,3H,4H,5H,6H- pyrrolo[3,4-c]pyrrol-2-yl)-3-hydroxy-2-phenylpropan-1-one, and preparation methods thereof. BACKGROUND [0003] Chemical compounds can form one or more different pharmaceutically acceptable solid forms, including amorphous and crystalline forms. Amorphous solid forms include dispersions, such as spray-dried dispersions, of amorphous and crystalline chemical compounds. Individual solid forms of bioactive chemical compounds can have different properties. There is a need for the identification and selection of appropriate solid forms of bioactive chemical compounds (including appropriate crystalline forms, where applicable) for the development of pharmaceutically acceptable dosage forms for the treatment of various diseases or conditions. [0004] The compound (S)-1-(5-[2H,3H-[1,4]dioxino[2,3-b]pyridine-7-sulfonyl]- 1H,2H,3H,4H,5H,6H-pyrrolo[3,4-c]pyrrol-2-yl)-3-hydroxy-2-phenylpropan-1-one (“Compound 1”),

, is a small molecule PKR activator which modulates pyruvate kinase activity. Compound 1 is described in International Publication No. WO 2018/175474 as one of many compounds suitable as small molecule modulators of pyruvate kinase activity. There remains a need for identifying solid forms of Compound 1 useful for various therapeutic applications. SUMMARY [0005] One aspect of the disclosure relates to solid oral dosage forms comprising a stabilized amorphous pharmaceutical composition of the compound (S)-1-(5-[2H,3H-[1,4]dioxino[2,3- b]pyridine-7-sulfonyl]-1H,2H,3H,4H,5H,6H-pyrrolo[3,4-c]pyrrol-2-yl)-3-hydroxy-2- phenylpropan-1-one (also referred to as “stabilized amorphous Compound 1”). As used herein, the term “stabilized amorphous Compound 1” refers to an amorphous solid form of Compound 1 that is stabilized (e.g., by combination with certain stabilizing polymers and/or other manufacturing processes) to prevent the formation of crystalline forms of Compound 1 or solid phase separation of Compound 1 under certain storage conditions described herein (e.g., stabilized amorphous pharmaceutical compositions comprising Compound 1 and one or more additional components that do not show crystalline diffraction peaks by XRPD analysis (Method D) after 2 weeks of storage at 60 °C/75% RH (exposed), and/or show a single glass transition temperature (T_G) with no melt endotherm by DSC analysis (Method B) after 2 weeks of storage at 60 °C/75% RH (exposed)). [0006] In some embodiments, the stabilized amorphous Compound 1 is obtained by spray drying a solution of Compound 1 with a stabilizing polymer. The inventors discovered that amorphous Compound 1 has higher oral bioavailability than certain crystalline forms of Compound 1, including crystalline form Type A. Accordingly, in some embodiments, solid oral dosage forms comprising stabilized amorphous Compound 1 advantageously provide superior oral bioavailability of Compound 1 in comparison to solid oral dosage forms comprising certain crystalline forms of Compound 1. [0007] Also disclosed herein are an amorphous spray-dried dispersion (SDD) of Compound 1, preparation methods thereof, and pharmaceutical compositions containing the same. The present disclosure provides various solid forms of Compound 1, including one or more pharmaceutically acceptable crystalline and amorphous forms for Compound 1, useful for the therapeutic oral administration of Compound 1. The various solid forms of Compound 1 can be identified by certain characteristic properties. For example, certain crystalline forms of Compound 1 have distinct characteristic XRPD peaks. [0008] Another aspect of the disclosure relates to solid forms of Compound 1.

The solution was diluted with EtOAc (20 mL), washed sequentially with water (20 mL) and brine (2x20 mL), dried (MgSCL), filtered, treated with silica gel, and evaporated under reduced pressure. The material was chromatographed by Biotage MPLC (10 g silica gel column, 0 to 5% MeOH in DCM) to provide a white, slightly sticky solid. The sample was readsorbed onto silica gel and chromatographed (10 g silica gel column, 0 to 100% EtOAc in hexanes) to provide (2S)- 1-(5-[2H,3H-[1,4]dioxino[2,3-b]pyridine-7-sulfonyl]-1H,2H,3H,4H,5H,6H-pyrrolo[3,4-c]pyrrol- 2-yl)-3-hydroxy-2-phenylpropan-1-one (106.5 mg, 0.233 mmol, 55 % yield) as a white solid. Example 2- Preparation and Characterization of Type A of Compound 1 Preparation of Type A of Compound 1 [0243] A 1L round-bottom flask with overhead stirring, a temperature probe, and an N₂ inlet was charged with 7-((3,4,5,6-tetrahydropyrrolo[3,4-c]pyrrol-2(1H)-yl)sulfonyl)-2,3-dihydro- [1,4]dioxino[2,3-b]pyridine (33.24 g, 96 mmol), (S)-3-hydroxy-2-phenylpropanoic acid (19.08 g, 115 mmol), and DMF (361 ml). The mixture was cooled to 0 °C, HATU (43.7 g, 115 mmol) was added, and a mild ~ 5 °C exotherm was observed. DIEA (70.2 ml, 402 mmol) was added dropwise over 20 minutes, and the pot was held near 0 °C. The reaction mixture was sampled after 2h and then after 3h. After 3h, an additional 50mL of DMF was added to thin the reaction mixture. [0244] After 3.5h at 0 °C, 37 volumes of DCM was added to the reaction mixture, and the solution was transferred to a 4L separatory funnel and washed with water (2060mL). The organic layer was then washed 3 X 2060mL of brine (26% W/W NaCl) and dried overnight with MgSO4. The solution was concentrated on a rotary evaporator to afford a waxy white solid (>80g). [0245] The solids were triturated with 500 mL of 5:4 EtOAc/hexanes, filtered, washed with 100 mL of 1:1 EtOAc/Hexanes, and dried in a vacuum oven at ambient temperature to afford 50.3 g of a white solid. [0246] The resulting material was ground in a mortar, charged to a 3 L round-bottom flask with overhead stirring and slurried with 1900 mL of ethanol. The slurry was heated to 76 °C, and water was added dropwise. After 40 mL of water had added, the mixture was filtered with a Buchner funnel. The filtrate was charged back to the round-bottom flask, stirred overnight, and cooled slowly to room temperature. [0247] The resulting slurry was cooled to 10 °C, stirred for 1 h, and filtered. The round-bottom flask and filter cake were washed with 100 mL of ethanol. The filter cake was dried on the funnel for 1 h, and overnight in a vacuum oven at ambient temperature to afford 38.43 g of Compound 1 a white solid, which was designated as Type A of Compound 1. Characterization of Type A of Compound 1 [0248] Type A was characterized by XRPD (Method A), TGA (Method A), DSC (Method A), and DVS analysis. [0249] The XRPD pattern for Type A is depicted in Figure 3, and the corresponding data are summarized in the following table:

[0250] The foregoing XRPD data for Type A can also be rounded to a single decimal place, as summarized in the following table:

[0251] The TGA and DSC curves for Type A are shown in Figure 4. As shown in Figure 4, Type A showed 1.9% weight loss up to 100 °C by TGA and two endotherms at 85.9 ºC (peak temperature) and 146.0 ºC (onset temperature) by DSC. [0252] By DSC cycling as shown in Figure 5, Type A was heated to 120ºC and cooled to 25ºC, then heated up to 300ºC. No endotherm below 100ºC was observed in the second heating cycle. XRPD analysis after DSC cycling showed no form change compared to Type A (Figure 3). [0253] DVS results showed a 3.4% water uptake up to 40% RH (ambient condition), and 1.0% water uptake from 40% RH to 80%RH at RT, indicating that Type A is hygroscopic (Figure 6). No form change was observed for Type A before and after DVS test at RT, as determined by XRPD. [0254] Based on the foregoing analytical data, Type A is believed to be a channel hydrate.

This solution was then placed into a 20-mL vial with 3 mL of anti-solvent. The 20-mL vial was sealed with a cap and kept at RT, allowing sufficient time for organic vapor to interact with the solution. After 7 days, solids were isolated for XRPD analysis (Method A). The results summarized in Table 11 showed that Type A and B were generated. Table 11

After being vortexed and ultrasonically shaken, the suspension was filtered, and the filtrate was transferred to a clean 4 mL shell vial. A small amount of Compound 1 (Type A) was added as a seed crystal. Subsequently, the shell vial was sealed with a polyethylene plug with one pinhole and enclosed in a 20 mL glass vial containing 3 mL of the anti-solvent at room temperature for liquid vapor diffusion. The solid forms resulting from the experiments were characterized by XRPD analysis (Method C). Table 12

If the solids were not dissolved completely, suspensions were filtered using a PTFE membrane (pore size of 0.2 mm) and the filtrates were used for the follow-up steps. The visually clear solutions were subjected to evaporation at RT with vials sealed by Parafilm^® (3-5 pinholes). The solids were isolated for XRPD analysis (Method A), and the results summarized in Table 13 indicated that only Type A was obtained. Table 13

[0261] Another series of slow evaporation experiments was performed under the conditions set forth in Table 14. Compound 1 (Type A) was weighed into a 3 mL glass vial with the addition of the corresponding solvent or solvent mixture. After being vortexed and ultrasonically shaken, the suspension was filtered, and the filtrate was transferred to a clean 4 mL shell vial.

Subsequently, the shell vial was sealed with a polyethylene plug with one pinhole and placed in a fume hood at room temperature for slow evaporation. The solid forms resulting from the experiments were characterized by XRPD analysis (Method C). Table 14

Anti-solvent Addition [0262] A total of 8 anti-solvent addition experiments were carried out. About 15 mg of Compound 1 (Type A) was dissolved in 0.2-4.0 mL of solvent to obtain a clear solution. The solution was magnetically stirred followed by addition of 0.2 mL anti-solvent per step until precipitate appeared or the total amount of anti-solvent reached 15.0 mL. The obtained precipitate was isolated for XRPD analysis (Method A). Results in Table 15 showed that Type A and amorphous material were generated. Table 15

After being vortexed and ultrasonically shaken to accelerate dissolution, the suspension was placed in a biochemical incubator and equilibrated at 50 °C for 30 minutes. The hot suspension was then filtered with a syringe filter (0.045 µm PTFE filter membrane, and the hot filtrate was transferred to a clean 3 mL vial (pre-heated at 50 °C). The vial was sealed and placed in an incubator for slow cooling from 50 °C to 5 °C at a rate of 0.01 °C/minute. The solid forms resulting from the experiments were characterized by XRPD analysis (Method C). Table 17

Example 16 - Preparation and Characterization of the Spray-Dried Dispersion of Compound 1 [0322] A Spray Dried Dispersion (SDD) of Compound 1 was prepared. The SDD was made up of Compound 1 and a polymer (Hydroxypropylmethyl Cellulose AS-MG) at a 1:3 weight ratio. Compound 1 and the polymer were dissolved in organic solvents (Dichloromethane and Methanol) and spray dried to obtain amorphous an amorphous drug substance. The SDD comprising Compound 1 and HPMC AS (1:3) is referred to herein as SDD 0. [0323] A spray solution was prepared at 7.8% solids content (1:3 Compound 1:HPMC AS- MG) in 80:20 DCM:Methanol per Table 18. An API correction factor of 0.966 was used to prepare the spray solution. The spray solution was prepped by adding DCM and Methanol to a 36L stainless steel mixing vessel. HPMC AS-MG was added to the solvent system while mixing with a top down mixer at a medium vortex. Compound 1 was then added to the solution. The solution had a yellow/brown clear appearance, however white fiber particulates were seen in the solution. Table 18

Correction Factor: 0.9660 [0324] A Mobile Minor spray-drying apparatus was setup per Table 19 and warmed up for approximately one hour prior to spraying. Wash solution (80:20 DCM:Methanol) was sprayed prior to the active solution to allow the nozzle to equilibrate. The Compound 1 active solution was sprayed per the settings in Table 19. The spray-dried dispersion was dried overnight (~20 hours) in a Shel Vacuum Oven at 50°C and -25 in Hg vacuum under a nitrogen purge at 15 scfh. The resulting spray-dried dispersion was confirmed to be dry by GC analysis. This run generated approximately 2.1 kg of spray-dried dispersion. Table 19

[0325] The SDD was characterized by XRPD (Method B) and DSC analysis (ambient to 200°C, 2°C/minute ramp), as shown in Figures 30 and 31, respectively. The SDD was determined to be homogenous and amorphous, as shown by the amorphous diffractogram, lack of a crystalline melt, and a single Tg at 100°C. Example 17- Bioavailability of the Spray-Dried Dispersion (SDD) of Compound 1 in Rats and Mice [0326] The systemic exposure of Compound 1 in rats and mice was evaluated by dosing a SDD made up of Compound 1 and HPMC AS-MG (1:3) (SDD 0, which can be prepared as described in Example 16) dispersed in an aqueous vehicle (0.5% Hydroxypropylmethyl Cellulose in water). The SDD formulation (“500 mpk SDD”) dosed at 500 mg/kg to rats showed an AUClast that was 40X greater than the maximum exposure obtained with the standard formulation (“300 mpk Suspension” made up of Compound 1 (Type A) in 10% Propylene Glycol, 10% Cremophore, 80% Water), as shown in Table 20 and Figure 32. Additionally, the exposure of a 500 mpk Nano- Suspension made up of nanoparticles of Compound 1 (Type A) was evaluated, as shown in Figure 32. Robust exposure was observed with SDD formulation in mouse as well. Table 20

Example 18- Bioavailability of the Spray-Dried Dispersion of Compound 1 in Monkeys [0327] Several formulations of Compound 1, including an SDD made up of Compound 1 and HPMC AS-MG (1:3) (SDD 0, which can be prepared as described in Example 16), were evaluated in monkeys. The compositions of the tested formulations are listed in Table 21. Table 21

[0328] The formulations were evaluated for pharmacokinetic parameters in monkeys and are shown in Figure 33. The profiles show that the SDD formulation (Formulation 4) provided a significant enhancement in overall exposure compared to the encapsulated formulations (Formulations 1, 2, and 3). The bioavailability enhancement with the SDD formulation is approximately 50-62%, which is several fold higher compared to the other formulations, at a dose equivalent to 100 mg. Example 19- Time-dependent Solubility of Type A of Compound 1 and the Spray-dried Dispersion of Compound 1 in Biorelevant Media [0329] The solubility of Type A of Compound 1 was evaluated in aqueous media. Aqueous solubility samples of Type A of Compound 1 were saturated with solid content. Samples were shaken at 37°C for 24 hours. Each aqueous media was also sampled after 30 minutes and filtered/diluted using the same procedure to be used for the t = 24-hour samples. Sample pH was only measured after 24-hour equilibration. [0330] Following 24-hour equilibration, the pH of the saturated samples was measured, and the mixtures were centrifuged through 0.22 mm nylon filters at 15,000 rpm for approximately 2 minutes. All centrifuged samples were diluted with method diluent and analyzed by HPLC (Method A). If no solids were present after overnight equilibration, the solubility was reported as “³” to the determined value. The concentrations reported are based on a single point calibration at the method nominal and are reported as the free form. Results are shown in Table 22 and Figure 34. Table 22

[0331] Solubility of the 1:3 Compound 1: HPMC-AS-MG spray-dried dispersion (SDD 0, which can be prepared as described in Example 16) was assessed in aqueous media at various timepoints over 24-hours. Individual saturated samples were prepared for each anticipated time point by adding ~10mg of SDD material to 1.5mL of solvent. Samples were placed at 37°C on a thermal shaker at 600RPM and pulled at t= 2min, 5min, 15min, 30min, 1hr, 2hr, 4hr, 6hr, and 24- hours. The mixtures were centrifuged through 0.22 mm nylon filters at 15,000 rpm for approximately 5 minutes. All centrifuged samples were diluted with method diluent and analyzed by HPLC (Method A). Sample pH was measured only at 24-hours. Results are shown in Table 23 and Figure 35. Table 23 ¹

Solids observed in centrifuge filter, resuspended in case of supersaturation, however high value suggests faulty filter. Time point omitted from the solubility profile in Figure 35. [0332] The solubility of the SDD was significant, particularly at earlier time points. Solubility of the SDD after four hours was 72.4µg/mL in FaSSIF and 558.5µg/mL in FeSSIF. Four-hour solubility of the SDD is 273.5µg/mL in SGF. The solubility decreased after 24-hour equilibration in all aqueous media tested. Example 20 - Stability Assessment of the Spray-Dried Dispersion of Compound 1 [0001] Stability studies were conducted on two distinct lots of the 1:3 Compound 1: HPMC- AS-MG spray-dried dispersion (SDD 0, which can be prepared as described in Example 16) under the conditions outlined in Table 24. The results of the stability study for each lot and storage condition are reported in the Tables identified in Table 24. The results for Lot 1 at the 5 month time point and Lot 2 at the 1 month time point remained consistent with the T=0 time points. Table 24

Example 21 - Preparation and Characterization of Spray-Dried Dispersions of Compound 1 [0333] Spray solutions having varying ratios of Compound 1 to polymer (Hydroxypropylmethyl Cellulose AS-MG) were prepared at 8% solids content in 80:20 DCM:MeOH (Table 30). The spray solutions were spray dried using a Procept 4M8-Trix unit with the settings detailed in Table 31. The resulting spray dried dispersions (SDDs) were dried at 50 °C at -25 in. Hg in a nitrogen purged vacuum oven for 19 hours. The SDDs were evaluated by XRPD analysis (Method D; Figure 36) and DSC analysis (Method B; Figure 37). The SDDs appeared amorphous by PXRD analysis, with no crystalline diffraction peaks observed. A single well defined T_G was seen by DSC for all dispersions. No melt endotherm was observed, further verifying the amorphous nature of all spray dried dispersions. Residual solvent analysis of the spray dried dispersions dried for 19 hours showed varying levels for dichloromethane. An observed trend is that levels of dichloromethane increase with increased ratios of Compound 1 to Polymer. Table 30

Example 22 - Preparation and Characterization of Spray-Dried Dispersions of Compound 1 [0334] Spray solutions having varying ratios of Compound 1 to polymer (Hydroxypropylmethyl Cellulose AS-MG) were prepared at 12% solids content in 80:20 DCM:MeOH (Table 32). The spray solutions were sprayed on a GEA Mobile Minor spray dryer, and the SDDs were collected and dried at 50 °C and -25 in Hg under a N₂ purge. Table 32

Example 23 - Kinetic Solubility of Compound 1 SDDs [0335] A µDISS Profiler™ instrument from Pion, Inc was used to quantify concentrations during equilibrium solubility experiments involving SDD 0 (which can be prepared as described in Example 16) and SDDs 1-4 (which can be prepared as described in Example 21). The unit consists of six photodiode array (PDA) spectrophotometers, each with its own dedicated fiber optic dip probe, center-positioned in the glass vial holding 10 mL of media. The concentration measurements are performed directly in the assay media, with processed results plotted in “real time.” [0336] Probes with 2-mm path length tips were selected for quantification of Compound 1 in SDD. The developed calibration curves were used for quantification of Compound 1 in the samples during kinetic solubility experiments at each time point. The 2-mm path length tips were selected for detecting concentrations of Compound 1 in both SGF and FaSSIF media. [0337] Standard calibration curves were generated in the respective assay media using a serial addition protocol. A stock solution of Compound 1 was prepared in DMSO at ~20 mg/mL. Calculated aliquots of the stock were added to the respective buffers in order to prepare several standard solutions spanning specific concentration ranges. Concentrations of the standard solutions ranged from ~50 to ~300 µg/mL for channels in both SGF and FaSSIF media respectively. The area under the 2^nd derivative curves was used to calculate the concentrations. The wavelength range was selected for the compounds in such a way that sensitivity issues were avoided. Linearity of the standard curves in the selected wavelength regions were characterized by r²³0.999. [0338] Area under the 2nd derivative curve in 285-300 nm (SGF) and 305-320 nm (FaSSIF) range were used to calculate the standard curves in respective media. The corresponding standard curves were used to determine concentrations of Compound 1 in solubility assays. [0339] Required amount of SDD materials, equivalent to 20 mg of Compound 1 were weighed into 20mL glass vials. The vials were then transferred to the instrument for analysis. A clean stir bar was added to the vial with sample. 16mL of SGF buffer was transferred to the vials before beginning the experiment to achieve an upper limit of ~1.25mg/mL. The stirring was maintained at 220 RPM and the temperature of the medium at 37°C. Kinetic solubility data was collected for 30 minutes in SGF media. The data showed that all the SDD’s at different loadings exhibited very similar release profile and achieved about same concentration of Compound 1 (~300µg/mL). [0340] At the 30-minute interval, the media was converted to FaSSIF 6.5. The final volume in the vials was increased to 20mL from 16mL (1.00mg/mL). The resulting samples were then analyzed using the µDiss Profiler for ~18H in FaSSIF. [0341] The SDD 0 formulation with 25% drug loading reached higher solubility of ~700µg/mL but did not remain in the supersaturated state for longer time. Although the solubility of SDD 0 at 4H was slightly lower than the 40% API loading SDD 1, the equilibrium solubility after ~16 hours was higher than all other SDD systems. SDD 3 and SDD 4 did not reach as high of a concentration (spring effect) as SDD 0. However, SDD 3 and SDD 4 both stayed at supersaturated state for longer time when compared to all other SDD systems tested. However, the equilibrium solubility for SDD 3 and SDD 4 after 16 hours was lower than SDD 0. SDD 2 and SDD 3 show marked enhancement in the solubility and prolonged supersaturation. The Kinetic solubility profiles are shown in Figure 38. [0342] The results are summarized in Table 33. All the solubility Results reported in the table are an average of n=2 replicates. Table 33

Example 24 - Stability of Spray Dried Dispersions of Compound 1 [0343] Spray dried dispersions of Compound 1 (SDD 0 (which can be prepared as described in Example 16) and SDDs 1-4 (which can be prepared as described in Example 21)) were set up on a short-term stability study in two different storage configurations at various storage conditions. Samples were set up as “Sealed” and “Exposed”. Sealed samples were placed into crimp sealed vials and stored in a single storage condition; 60°C. The exposed samples were placed into a vial that was covered lightly with perforated foil to allow exposure to the humidity conditions. The exposed samples were stored at 40°C/75%RH and 60°C/75%RH. Samples were pulled after T = 1 and 2 weeks for PXRD analysis (Method D). [0344] PXRD diffractograms taken after 2 weeks for SDDs 0-4 are provided in Figures 39-43, respectively, and the results are summarized in Table 34. SDDs 0, 1, 2 and 3 showed amorphous character by PXRD at all tested conditions through 2 weeks. SDD 4 showed crystallinity by PXRD after 2 weeks of storage at 60 °C/75% RH (exposed). SDD 4 also showed two glass transition temperatures by DSC (Method B) after 2 weeks of storage at 60 °C/75% RH (exposed), suggesting phase separation. Table 34

Example 25 - Stability of Spray Dried Dispersions of Compound 1 [0345] Spray dried dispersions of Compound 1 (SDDs 5 and 6 (Example 22)) were stored in two different storage configurations at various storage conditions. Samples were set up as “Sealed” and “Exposed”. Sealed samples were stored in an amber crimp sealed vial at the following conditions: 2-8°C, 25°C/60%RH, 40°C/75%RH, and 60°C. Exposed samples were stored in an amber crimp vial covered with foil, which was perforated to allow exposure to humidity, at the following conditions: 25°C/75%RH, 40°C/75% RH, and 60°C/75% RH. [0346] Samples were analyzed by PXRD (Method D) and/or DSC (Method B) analysis at T = 0, 1, and 2 weeks. Results are summarized in Table 35. No crystalline diffraction peaks were observed by PXRD in any sample. Moreover, a single TG and no melt endotherm was seen by DSC in all samples. Table 35

[0347] Kinetic dissolution of SDD 5 and SDD 6 samples was determined at T = 0 and T = 1 week (40 °C/75% RH Exposed; and 40 °C/75% RH Sealed) using the procedure described in Example 23. The results are summarized in Table 36. Table 36

Example 26 - Composition and Preparation of a Tablet Dosage Form of Compound 1 Composition of the Tablet Dosage Form [0348] A tablet dosage form of Compound 1 comprising an SDD made up of Compound 1 and HPMC AS-MG (1:3) compressed into tablets and film coated with compendial excipients was prepared. The tablets were presented as 25 mg (white coated round shaped tablets) and 100 mg (white coated oval shaped tablets) dose strengths. The composition of each dosage strength is summarized in Table 37. Table 37

1= Quantity based upon a 25.00% (w/w) potency of Compound 1 drug substance in the spray dried intermediate. Preparation of the Tablet Dosage Form [0349] The Compound 1 tablet formulation manufacturing process consists of four steps: 1) spray dry dispersion, 2) intragranular granulation, roller compaction/milling/blending, 3) extragranular granulation/blending, and 4) tableting and coating. The initial step of spray dry dispersion is performed by creating an organic solution containing Compound 1 drug substance, and Hypromellose Acetate Succinate (Hydroxypropyl Methylcellulose Acetate Succinate MG) (HPMCAS-MG). The solution is spray dried to produce an SDD made up of Compound 1 and HPMC AS-MG (1:3), using a method analogous to the method of Example 16. The SDD is blended with intra granular excipients followed by roller compaction/milling and blending. The resulting granulation is then mixed with the extra-granular components to create the final common granulation blend. The final blend is pressed into tablets equivalent to either 25 mg or 100 mg active followed by coating. Example 27 - Dissolution Assessment of the Tablet Dosage Form [0002] The 100 mg tablets described in Example 26 were tested for dissolution. Dissolution testing parameters are provided in Table 38, and results are summarized in Table 39. Table 38

Example 29- Stability Assessment of the Tablet Dosage Form [0351] Stability studies were conducted under the conditions outlined in Table 42 on two distinct lots of 25 mg and 100 mg tablets having the composition specified in Example 26. The results of the stability study for each lot and storage condition are reported in the Tables identified in Table 42. [0352] The tablets were prepared for XRPD analysis (Method D) by crushing a tablet with a mortar and pestle and transferring 5-10 mg of material to a sample pan, slightly overfilling and ensuring that powder is spread evenly to cover the bottom of the plate. Weigh paper was placed atop the powder and pressed down gently to even the powder surface. The XRPD pattern of the tablet was overlaid with the XRPD pattern of a reference standard (Compound 1, Type A). A tablet was deemed to be free of the diffraction peaks that are present in the reference standard only if the peak at ~15 degrees 2-theta is absent. A small, irregular peak at ~3 degrees 2-theta is acceptable. Table 42

[0353] The results for the tablet batches from Lot 1 at the 3 month time point and Lot 2 at the 1 month time point remained consistent with the T=0 time points. Example 30 - Composition and Preparation of a Tablet Dosage Form of Compound 1 [0354] Tablets comprising a spray dried dispersion (SDD) of Compound 1 and compendial excipients are prepared at 100 mg and 200 mg dosage strengths. The compositions of the tablets are set forth in Tables 51 and 52. [0355] The tablets are prepared by first manufacturing the SDD (spray drying an organic solution of Compound 1 and HPMC-AS (1:1 w/w) (Table 51) or an organic solution of Compound 1 and HPMC-AS (1.5:1 w/w) (Table 52)), followed by roller compaction/milling with intragranular excipients and blending with extragranular excipients. The final blend is pressed into tablets and then film coated. Table 51

Example 31 - Stability Assessment of the Tablet Dosage Form [0356] Tablets having the compositions set forth in Tables 51 and 52 were prepared for XRPD analysis (Method D) by crushing a tablet with a mortar and pestle and transferring 5-10 mg of material to a sample pan, slightly overfilling and ensuring that powder is spread evenly to cover the bottom of the plate. Weigh paper was placed atop the powder and pressed down gently to even the powder surface. The XRPD pattern of the tablet was overlaid with the XRPD pattern of a reference standard (Compound 1, Type A). The XRPD pattern of a tablet was deemed to be free of the diffraction peaks that are present in the reference standard only if the peak at ~15 degrees 2-theta is absent. A small, irregular peak at ~3 degrees 2-theta is acceptable. The tablets were determined to be free of crystalline Type A because the XRPD patterns were free of the diffraction peaks that are present in the reference standard. Example 32 – Determination of Maximum Dose of Compound 2 [0357] Good Laboratory Practice (GLP) toxicology testing of a Compound 1 test article comprising a pre-determined amount of Compound 2 was performed in rat and cynomolgus monkeys. A no-observed-adverse-effect level (NOAEL) was determined for each species using standard toxicology techniques, and a resulting dose level for humans was calculated using the FDA Human Equivalent Dose approach based upon dose per body surface area. Based on these experiments and calculations, a maximum recommended starting dose (MRSD) for first-in-human clinical trials was determined based on results from GLP toxicology testing. API compositions of Compound 1 containing less than 5.0% (as determined by percentage area HPLC) of Compound 2 are well within the safe human equivalent dose determined for Compound 2.
