Suspensions of each ASD were prepared in three biorelevant media, namely: SGF, FaSSIF, and FeSSIF. These suspensions were stirred at 400 rpm. An aliquot of the supernatant was withdrawn at 5 min, 10 min, 30 min, and 4 hours, syringe- analyzed by HPLC. The sol presented in Table 2A-20.

Both ASDs stored remained amorphous up to 12 weeks storage under the above- mentioned conditions (Fig.21). The mDSC of the stability samples was carried out in a hermetically sealed pan without any pin hole, to determine the Tg in the presence of residual solvent or moisture (i.e., wet Tg). Results pertaining to mDSC and TGA analysis are summarized in Table 2A-21 and presented in Fig.22 and Fig.23. Both ASDs stored at 40°C/33% RH for six weeks showed lowest weight loss and highest Tg compared to other storage conditions, which could be result of partial drying of the sample at 40°C/33% RH (compared to starting material’s initial storage condition of 25°C and 60-70% RH). In most of these conditions, the Tg of both ASDs was within 10% of the initial Tg value, except for Elra:CAP, which showed ~11.5% decrease in Tg value compared to initial Tg. [00447] HPLC analysis of both ASDs stored at all three conditions did not show any degradation when monitored at 438 nm, it only showed peaks for the known impurity at amorphous samples, ssNMR produces gaussian curves that when applied to first derivative become a flat baseline. Crystalline material produces Laplacian curves by ssNMR which can be clearly observed after applying the first derivative. [00449] Signal to noise ratio of API reference was 8.18. In all four stability samples, the signal to noise ratio for the first derivative peak at 87 ppm remained <2. Results are summarized in Table 2A-26. [00450] The results of the CPMAS ssNMR showed no detectable crystallinity in any of the ASDs tested after their exposure to both the stability conditions. Table 2A-21.

A Chemagnetics APEX probe, refitted with a 7mm magic angle spinning module (Revolution NMR, Fort Collins, CO) was used to acquire the data. Each sample was packed into a 7 mm zirconia rotor with Kel-F spacers. The magic angle spinning (MAS) frequency that was used to acquire all of the data was 5 kHz.13C chemical shifts are reported relative to the methyl peak of 3-methylglutaric acid at 18.84 ppm with an accuracy of ±0.4 ppm. [00460] Saturation recovery was used to measure 1H T1 relaxation times.13C spectra were collected using a pre-saturation period (1H ^/2, 15 ^s delay, loop 20x), variable delay, 1H ^/2 pulse, and then the cross polarization total suppression of spinning sidebands (CPTOSS) sequence, and 1H SPINAL-64 decoupling. The T1T2 function in the Bruker Topspin 4.0.8 software package was used to determine the 1H T1 values of the samples. The 1H T1rho values were determined by 1H ^/2 pulse, variable pulse (0.5 – 64 ms), and then the cross polarization total suppression of spinning sidebands (CPTOSS) sequence, and 1H SPINAL-64 decoupling. The T1T2 function in the Bruker Topspin 4.0.8 software package was used to determine the 1H T1rho values of the samples. High quality 13 C CPTOSS spectra were acquired at 5 kHz MAS using the CPTOSS sequence, a 1.5 ms contact time, 3960 acquisition points (~50 ms acquisition time).

A plastic spatula was rolled over a < 100 mg sample then carefully rolled over double-sided adhesive carbon paper on top of the stage to prepare the sample. Three left-handed rotations of the sample holder were used to position the sample approximately 2 mm below the top of the stage for imaging. Preparation of Elra:CAP ASD and Elra:CAP tablets For Example 2B Preparation of the Elra:CAP ASD: [00487] Elraglusib and CAP were weighed and dispensed into a 1.0 L or 2.0 L graduated media storage bottle. The materials were dissolved in THF to produce about 8% weight by weight (w/w) total solids spray solution. The solution was stirred for 30 minutes prior to spraying to ensure full dissolution of the solids. The B-290 mini spray dryer was set up per the parameters summarized in Table 2B-6 and in Table 2B-7. After reaching the target oxygen percentage of not more than (NMT) 6% (actual value: lot 35044-004 – 4.6%, lot 35044-030 – 2.0%), the heater was turned on and the inlet temperature set to 100°C. Once the inlet temperature was reached, the outlet temperature was allowed to stabilize. Pure solvent was run until a steady state was reached. Upon reaching steady state, spraying of the elraglusib/CAP mixture in THF was initiated using a 30% pump flow rate and size 14 L/S tubing. After spraying as much of the product as possible and allowing the apparatus to cool, the product was collected and oven dried at 60°C overnight. Table 2B-6.

Intragranular ingredients were added and blended in a mortar for 1 minute. Water for Injection was added to 30% w/w at approximately 2.5 g/minute. Wet massing time of 1 minute was allowed for the blend prior to transfer of the blend to the oven at 60°C for 6 hours. At the end of this time loss on drying was measured and a 1.00 mm mesh was used for granulation of the dried blend. The blend was weighed to calculate the adjustment factor for extragranular excipients. Extragranular MCC and CSS were added to the HPDE container, and the mixture was blended for 50 revolutions. Magnesium stearate was added to the mixture and blended for an additional 50 revolutions to produce the final blend. Non-micronized API Wet Granulation – Prototype: [00498] Intragranular ingredients were added to the high shear wet granulator adding half of the MCC prior to the non-micronized API and excipients and the second half of the MCC on top of the 1.0 L bowl. The ingredients were homogenized by dry mixing in the GlobePharma High Shear Granulator1-6 for 3 minutes with an impeller speed of 300 rpm and chopper speed of 1000 rpm. Wet granulation was initiated using an impeller speed of 300 rpm and chopper speed of 1000 rpm with a spray rate of approximately 10 mL/minute.

Elra:ASD Characterization: [00501] Elra:CAP from batch 35044-004 was characterized by XRPD (Fig.31) showing a e d [ y product and SEM imaging showed mixed morphology typical of an ASD process. Micronized Elraglusib API: [00503] Elraglusib API was micronized using a jet mill and evaluated for compressibility. Characterization of Micronized elraglusib API: [00504] SEM images (Fig.33), particle size distribution (PSD, Fig.34) and XRPD (Fig. 35) were performed on elraglusib material before and after jet milling for evaluation of the micronization process. SEM, PSD, and XRPD data before and after milling were as expected. A bimodal particle size distribution was observed after milling which may be due to a single pass in the mill.

[00518] Plasma concentrations of elraglusib were determined for dogs treated with 20 mg/kg elraglusib via oral administration on Day 1 and then again via intravenous infusion on Day 8. Systemic exposure was achieved in all animals following both oral and intravenous administration of elraglusib. Intravenous administration resulted in higher elraglusib plasma concentrations, compared to oral administration. Individual plasma concentrations were highest approximately 2-8 hours after oral administration (1,410-1,880 ng/mL), and highest at approximately 5 minutes following intravenous administration (11,800-13,600 ng/mL). [00519] Overall, the half-life was similar by both the oral and IV routes of administration. Group mean C max was approximately 7.5 fold greater for the IV versus the PO route and AUC last was approximately 3 fold greater for the IV versus the PO route. Comparing the plasma AUC values for dosing by oral gavage (21,300 hr*ng/mL) versus IV injection (68,900 hr*ng/mL), permits estimating oral percentage bioavailability (%BA) as 100*(21,300/68,900) = 31 %BA.

PK Study 2 – Bioavailability of oral solution, oral suspension, and Elra:CAP and Elra:PVAP capsule dosage forms in dogs [00520] A five-way cross-over study was conducted in which three animals were first dosed at 10 mg/kg by IV injection using 10 mg/mL elraglusib in PEG400:EtOH:Water (85:10:5 %w/w). [00521] Three male non-naïve and/or naïve beagle dogs are selected for use in this study. The animals are 7-12 months old and weigh 8-12 kilograms at the start of the quarantine period for this study. The actual body weights and ages may vary but will be recorded and maintained with the raw data. [00522] Approximately 250-350 grams of Harlan Teklad Certified Canine Diet # 2025 (or other suitable diet as documented in the study record) was provided to each animal on a daily basis. Each lot of diet is analyzed for contaminants to ensure that none are present at concentrations which would be expected to interfere with the conduct or purpose of this study. In addition, each dog receive d a commercially available canned dog food to ensure animals were i fed-state prior to dosing. The canned dog food ½ -1 can was provided at a minimum of 1 hour prior to each administration. The lot and brand of the dog food was documented in the study record. [00523] The study was composed of a single group of 3 dogs each receiving 5 administrations of elraglusib dosage forms, each administration separated by a minimum of a 3-day treatment free period (wash-out). The first administration was a single intravenous (IV) infusion dose of elraglusib TA #1 (10 mg/mL in PEG400:EtOH:water, 85:10:5 %w/w) followed by an oral dose of TA #2 (Elra:CAP capsules, 100 mg elraglusib), followed by an oral dose of TA #3 (Elra:PVAP capsules, 100 mg elraglusib), followed by an oral gavage dose of TA#4 (a 2 mg/mL oral suspension formulation), followed by an oral gavage dose of TA#5 (a 50 mg/mL oral solution). Animals underwent standard evaluations such as body weight and clinical observations, and were bled for pharmacokinetics preceding and following each dose. The Study 2 experimental design is summarized in Table 3-4.

Notes: After bolus IV administration of elraglusib, dogs were re-used for oral gavage and capsule administration of elraglusib after a minimum of 3 day washout period between each dose. [00524] Dogs received a single 15-minute intravenous infusion of the test article into the cephalic vein (or other suitable vessel). The test article (TA #1) was infused into the cephalic vein (or other suitable vessel). After IV administration dogs received 4 additional oral (gavage or capsule) administrations of the test articles (TA # 2, 3, 4, and 5) in the order of the Test Article #. For IV and oral gavage administration the doses were based on the most recent body weight. For capsule administration the pre-filled capsules were weighed prior to dosing, and the was back calculated based on the dogs weight. [00525] Blood samples were collected from the jugular vein (or other suitable vessel) into 2 mL vacutainer tubes containing K2EDTA as anticoagulant from each dog at the following timepoints: a) Intravenous administration: Prior to (0) and at 5, 15, 30, 60 minutes, as well as at 2, 4, 8, and 24 hours following the end of the injection. The zero hour (trough) was collected within approximately 24 hours prior to dosing. b) Oral administration: Prior to (0) and at 15, 30, 60 minutes, as well as 4) 10 mg/kg using elraglusib 50 mg/mL in Vehicle Variant 7 after dilution to a 2-mg/mL suspension in 5% Dextrose Injection (D5W). [00527] Blood samples were drawn at timed intervals plasma [elraglusib] determinations were made using a validated LC-MS/MS method. Table 3-5.

Compared with the two solid oral dosage forms, the 50 mg/mL Oral Solution in Vehicle Variant 7 demonstrated significantly shorter Tmax values (Tmax = 8 hr for the solid dosage forms versus Tmax=2 hr for the oral solution). PK Study 3. - Bioavailability of oral solution and tablet dosage forms in dogs [00529] Three male non-naïve beagle dogs were selected from an in- house pool of colony animals for use in this study. The animals were approximately 11-16 months old and weighed 10-12 kilograms at the start of the quarantine period for this study. [00530] Approximately 250-350 grams of Harlan Teklad Certified Canine Diet # 2025 (or other suitable diet as documented in the study record)was provided to each animal on a daily basis. Each lot of diet was analyzed for contaminants to ensure that none were present at concentrations which would be expected to interfere with the conduct or purpose of this study. In addition, each dog received a commercially available canned dog food to ensure animals were in a fed-state prior to dosing. The canned dog food ½ -1 can was provided at a minimum of 1 hour prior to each administration. [00531] City water was provided ad libitum to all animals by an automatic watering system. Supply water is analyzed for contaminants as defined by the U.S. EPA “National Primary Drinking Water Regulations” (Title 40, Code of Federal Regulations, Part 141). No known contaminants are expected to be present in the water that would interfere with the interpretation of the study. [ 2 E h i ifi i h h i i l i I [ ( L c a properly. [00534] Upon arrival and during the study, the dogs were group-housed (when possible) by sex in kennels or were single-housed in tandem cages equipped with companion doors to allow for socialization/exercise. Comingling was confined to animals with the same sex and dose group. Animals were individually housed during the dosing and observation phases. Each kennel or cage was equipped with an automatic watering system. [00535] Animal cages/kennels and rooms were cleaned and sanitized prior to placing animals in them, and periodically thereafter in accordance with accepted animal care practices and relevant standard operating procedures. [00536] The test Articles were as follows: [00537] TA #1 was 10 mg/mL elraglusib in Vehicle weight to volume solutions, micro- filtered using a syringe filter (or other suitable filtration system) and dispensed into sterile vials for use. The IV solution was prepared based on elraglusib assay value. The IV solution was administered by infusion at 10 mg/mL followed by a sufficient wash-out period. The vehicle is 85% PEG-400, 10% ethanol, 5% water (all components are weight/weight/weight). [00538] Tablets (TA #2): Each dog received one tablet of TA #2 orally followed by a sufficient wash-out period. [00539] Tablets (TA #3): Each dog received one tablet of TA #3 orally followed by a sufficient wash-out period.

Each received 5 administrations of elraglusib dosage forms, each administration was separated by a minimum of a 3-day treatment free period (wash-out). The first administration was a single intravenous (IV) infusion dose of elraglusib (TA #1) followed by an oral dose of TA #2 tablets, followed by an oral dose of TA #3 tablets, followed by an oral dose of TA #4 tablets, followed by an oral gavage dose of a 50 mg/mL oral solution (TA #5). Animals underwent standard evaluations such as body weight and clinical observations and were bled for pharmacokinetics preceding and following each dose.

) to: • UV or visible light in a calibrated photo-chamber, and • Ambient light. [00559] The photo-chamber and ambient light studies used a RP-HPLC method to monitor the following: • elraglusib concentration and %LC • elraglusib main peak Area % • elraglusib RelS1, elraglusib RelS2, and elraglusib Anhydride peak Area % values. [00560] The photo-chamber studies included the following experimental variables: • Pharmaceutical Vehicles/Solvents • Formulation Vehicle PEG400:EtOH:Polysorbate 8075:17:8 %w/w (“FV”) • Vehicle Variant 7 PEG400:EtOH:Polysorbate 8094:5:1 %w/w (“V7”) • PEG400 (“PEG-Only”) • PEG400:EtOH 95:5 %w/w (“PEG-E”) • PEG400:Polysorbate 8095:5 %w/w (“PEG-T”) • Acetonitrile (“AN”) • elraglusib Concentration (2-, 10-, 15-, and 50-mg/mL) • Light Source (UV versus Visible) • Exposure duration (0, 25, 50, 75 and 100% of ICH Q1B conditions) • Container (clear glass vials versus cuvettes with and without foil over-wrap) • Dissolved gases (oxygen sparge versus nitrogen sparge versus no sparge) [00561] The ambient light studies included the following experimental variables: • Primary Containers (clear versus amber glass vials) • Secondary Containers (translucent plastic divider boxes), and • Tertiary Containers (opaque cardboard boxes) [00562] The results of the three photo-chamber studies support the following conclusions: • For elraglusib in various solvents and over the concentration range 10- to 50- mg/mL, elraglusib %LC and main peak Area % values decrease approximately linearly with increasing light exposure. • The elraglusib photo-exposure %LC loss rates exceed the main Peak Area % rates by a factor of approximately 6 (due to the elraglusib absorbance maximum shift from ~440 nm in elraglusib to ~330 nm for elraglusib RelS2. • elraglusib photo-exposure loss rates versus visible light exposure increase in the following order for the solvents studied: AN<< PEG-Only ~PEG-E<FV<V7<PEG-T • elraglusib photo-exposure loss rates versus visible light exposure are essentially independent of elraglusib concentration over the range 10- to 50-mg/mL • elraglusib photo-exposure loss rates are approximately 5 times faster upon exposure to visible light compared with UV light • elraglusib photo-exposure loss rates for samples exposed to visible light are essentially independent of dissolved gas (oxygen versus nitrogen) • elraglusib %LC losses are significant (approximately 20% loss) for elraglusib Injection, Solution upon exposure to 100% of 1200 klux-hr visible light • elraglusib RelS1 peak Area% changes for elraglusib Injection, Solution upon exposure to 100% of 1200 klux-hr visible light are not quantifiable owing to incomplete resolution between elraglusib RelS1 and elraglusib RelS2 using the RP-HPLC method. • elraglusib RelS2 peak Area% increases are significant (increase to approximately 3 to 5% peak Area%) for elraglusib Injection, Solution upon exposure to 100% of 1200 klux- hr visible light • elraglusib Anhydride peak Area% values are either unchanged or decrease slightly for elraglusib Injection, Solution upon exposure to 100% of 1200 klux-hr visible light [00563] The results of the three ambient light studies support the following conclusions: • elraglusib Injection, Solution drug product in clear glass serum vials converts to elraglusib RelS2 upon exposure to ambient light over 28 days • Exposure to ambient light for 3 to 7 days has little impact, but elraglusib %LC and main peak Area % values decrease significantly after 14 to 28 days exposure while elraglusib RelS2 peak Area% values increase over the 7- to 28-day interval • Amber glass vials and the plastic divider cartons used as secondary packaging for the clear glass vials reduce, but do not completely protect against elraglusib photo- conversion upon ambient light exposure. • Placing clear glass vials in a plastic divider carton into an opaque cardboard box adequately reduces the rate of elraglusib photo-conversion upon ambient light exposure. Photo-chamber Studies Photo-chamber Study 1 [00564] The impact of light exposure on elraglusib in three solutions was examined, namely: • 10FV (10 mg/mL elraglusib in Formulation Vehicle, PEG400:EtOH:Polysorbate80 75:17:8 %w/w), • 50FV (50 mg/mL elraglusib in Formulation Vehicle), and • 50V7 (50 mg/mL elraglusib in Vehicle Variant 7, PEG400:EtOH:Polysorbate8094:5:1 %w/w). [00565] The 10FV solution is identical to elraglusib Injection, Solution. [00566] The three solutions were maintained in both 5-mL glass serum vials and UV- transparent plastic cuvettes (each with and without foil overwrap) and exposed to fractions (approximately 0, 25, 50, 75, and 100%) of ICH Q1B photostability conditions (1200 klux- hr in the visible region and 200 watt-h/m 2 in the UV region) using a calibrated photo- chamber. [00567] Photo-exposure converted elraglusib to elraglusib RelS2. Solutions exposed to ≤ 25 % of 1200 klux-hr visible light featured two partially-resolved peaks for elraglusib RelS1 and elraglusib RelS2 but the elraglusib RelS2 peak increased with increasing exposure interval and resolution between the two peaks decreased. [00568] elraglusib %LC and main Peak Area % values decreased linearly with increasing visible and UV light exposure interval. The %LC loss rate was approximately 6 times faster than the main peak Area% loss rate. [00569] %LC photo-conversion rates in vials (no foil) exposed to visible light were approximately 60% of the rates in cuvettes (no foil). Foil overwraps severely reduced the photo-conversion rates in both cuvettes and vials. [00570] %LC and main peak Area % photo-conversion rates in both vials and cuvettes were significantly faster under visible light exposure compared with UV light exposure. Photo-conversion was approximately 5 times faster upon exposure to visible light compared with UV light. [00571] For samples maintained in vials (no foil) and exposed to visible light, %LC and main peak Area % photo-conversion rates for 10FV were approximately 1.6 times higher than 50FV or 50V7 rates, whereas 50FV versus 50V7 photo-conversion rates were approximately equal. Table 4-1 below summarizes the photo-conversion rate comparisons. Table 4-1.

Under the same conditions, the elraglusib RelS2 peak Area % values increased to approximately 3 to 5%. elraglusib RelS1 peak Area % values were not reliably quantifiable owing to the incomplete resolution between the elraglusib RelS1 and elraglusib RelS2 peaks. Photo-chamber Study 2 [00573] The impact of photo-chamber visible light exposure on 10 mg/mL elraglusib in four Vehicles, namely: • FV (PEG400:EtOH:Polysorbate 75:17:8 %w/w, this is the elraglusib Injection Vehicle), • PEG-Only (100% PEG400), • PEG-E (PEG400:EtOH 95:5 %w/w) and • PEG-T (PEG400:Polysorbate 95:5 %w/w). [00574] Visible light photo-exposure converted elraglusib to elraglusib RelS2 in each of the four Test Articles. The elraglusib Anhydride related substance peak Area % values decreased slightly with increasing photo-exposure in all Test Articles. [00575] For all four Test Articles, elraglusib %LC and main Peak Area % values decreased linearly with increasing exposure interval. [00576] Table 4-2 below shows that %LC and main peak Area % photo-conversion rate (slope) values increased in the order: PEG-Only ~PEG-E<FV<PEG-T. Table 4-2. Slope Ratios for 10 mg/mL FV, PEG-Only, PEG-E, and PEG-T Test Articles Exposed to Visible Light Photo-Chamber Study 3 [00577] The impact of visible light exposure on elraglusib Test Articles that included the following: • 10FV (10 mg/mL elraglusib in Formulation Vehicle PEG400:EtOH:Polysorbate 75:17:8 %w/w), • 2AN (2 mg/mL elraglusib in acetonitrile). [00578] The 10FV Test Article is identical to elraglusib Injection, Solution drug product. The 2AN Test Article was included in this study to probe the effects of protic versus non- protic solvents on elraglusib photo-sensitivity and to supplement the prior photo-exposure study results with elraglusib in acetonitrile. [00579] The 10FV Test Articles were initially sparged with either oxygen or nitrogen and the 2AN Test Article was not sparged. [00580] The Test Articles were maintained in glass serum vials (25-mL fill in 50-mL vial) and exposed to fractions (0, 25, 50, 75, and 100%) 1200 klux-hr using a calibrated photo- chamber. [00581] For all four Test Articles, elraglusib %LC and main Peak Area % values decreased linearly with increasing visible light exposure interval. [00582] The %LC and elraglusib main peak Area % photo-conversion rates were essentially identical for both the oxygen-sparged and nitrogen-sparged samples. [00583] The elraglusib photo-conversion rate was significantly slower for the 2AN Test Article compared with the 10FV Test Article. [00584] For the 10FV Test Article, the elraglusib RelS2 peak Area % values increased slightly or did not change significantly with increasing visible light exposure interval. Ambient Light Study [00585] This ambient light study used the same Test Articles, analytical methods, and procedures as Photo-chamber Study 1except that Test Articles were exposed to ambient light for timed intervals (t= 0, 1, 3, 7, 14, 21, and 28 days). [00586] For all three Test Articles exposed to ambient light, elraglusib %LC and main peak Area% values remained essentially unchanged at the t = 0-, 1-, and 3-d timepoints, but then decreased approximately linearly with increasing exposure interval. Foil overwraps severely reduced the photo-conversion rates in both cuvettes and vials. [00587] Ambient light exposure converted elraglusib to elraglusib RelS2. The elraglusib RelS2 Area % values remained undetected at the t = 0-, 1-, and 3-d timepoints, but increased approximately linearly with increasing ambient light exposure time thereafter. The elraglusib RelS2 Area % values increased significantly faster for the 10FV Test Article than for the 50FV and 50V7 Test Articles, but the rate of increase was approximately equal for the 50FV and 50V7 Test Articles. Example 5 – Oral Solution Versus Intravenous Bioavailability in Human Volunteers [00588] Example 5 sets forth the results of the PK study 4 in Example 3. [00589] This pharmacokinetic (PK) study in healthy subjects was conducted to characterize and compare the PK parameters in plasma following a single intravenous (IV) dose of Elraglusib Injection, Elraglusib Oral Solution after fasting, and Elraglusib Oral Solution after a high-fat meal (fed). The study was intended to assess the potential feasibility of an oral formulation of elraglusib based on systemic exposure being within the biologically active range. In clinical studies conducted to date, elraglusib Injection (10 mg/mL) is administered IV once or twice per week over multiple hours, which requires a significant amount of time and resources by both patients and site personnel. An oral solution has been developed and PK Study 2 and PK Study 3 in fed-state dogs showed approximately ~ 70 to 80% dose-normalized bioavailability of the drug, which supports additional investigation. See Example 3 above. [00590] This open label, single center, phase 1, randomized, single-dose, crossover, PK study of elraglusib administered as an oral solution in fed and fasted states and as an IV infusion in healthy subjects was conducted in 18 subjects to compare the PK profiles of Elraglusib Oral Solution to Elraglusib Injection. [00591] The primary objectives of the study were: (1) Pharmacokinetics: to evaluate plasma pharmacokinetic (PK) of single dose elraglusib administered as an intravenous (IV) infusion and as an oral solution under both fasted and fed conditions in healthy subjects; and (2) Safety: to determine the tolerability of elraglusib administered as an IV infusion and as an oral solution. [00592] Patient population: Eighteen subjects received at least 1 dose of elraglusib and are included in the safety population. Eighteen subjects had at least 1 blood sample providing evaluable PK data for elraglusib and are included in the PK Evaluable population. Sixteen subjects had sufficient data to calculate at least one of the PK parameters of Cmax, AUC, or λz and are included in the PK Analysis population for each of the treatments. [00593] Inclusion criteria: [00594] Subjects were required to meet all the following criteria to be eligible for the study: 1.

Had positive urine alcohol test 14. Had positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test [00597] Randomization [00598] Subjects were randomized to receive 1 of 6 dosing sequences: 1. oral fed – oral fasted – IV 2. oral fed – IV – oral fasted 3. oral fasted – oral fed – IV 4. oral fasted – IV – oral fed 5. IV – oral fed – oral fasted 6. IV – oral fasted – oral fed [00599] The randomization followed a permuted block size of 6. There were no stratification factors to be implemented in the randomization schedule for this study. Subjects were randomized via a paper randomization schedule. [00600] Dosage Forms: [00601] Elraglusib Injection is a is a light red to red clear solution of 10 mg/mL elraglusib in an inactive co-solvent mixture of polyethylene glycol 400, ethanol and Tween 80 (polysorbate 80) (PEG400:EtOH:Tween80; 75:17:8). The route of administration is by IV infusion after diluting elraglusib for injection with 0.9% Sodium Chloride Injection. [00602] Elraglusib Oral Solution is 50 mg/mL elraglusib in Vehicle Variant 7, a co- solvent mixture of PEG400:EtOH:Tween80 (94:5:1 %/w/w). It is a clear, red solution, free of visible particulate matter and a low bioburden liquid dosage form that is self-preserving against microbial growth. [00603] Dose Administration: [00604] Elraglusib was administered on Day 1 of each of the 32-week study periods. [00605] Subjects received a single 3.3 mg/kg dose of each of the following in a randomly assigned order separated by a 2-week period. [00606] Elraglusib Oral Solution (50 mg/mL) in a fed state: Within a 30-minute period, a subject in a fed state consumed a high-fat meal (breakfast). The Elraglusib Oral Solution was also ingested within this 30-minute period. During the study, the high fat meal was administered over a period of under 30 minutes (in almost all cases, 28 minutes). The elraglusib dose was administered within 1 minute of the end of the meal, which in effect, resulted in the elraglusib oral dose being administered within 20 minutes of the start of the high fat meal. [00607] Elraglusib Oral Solution (50 mg/mL) in a fasted state: Subjects fasted overnight (except water) for at least 8 hours before administration of the oral solution. [00608] NOTES for Oral Dosing: [00609] Subjects were not to have their post-dose meal for at least 4 hours after the Elraglusib Oral Solution was ingested. [00610] Subjects were not to eat or consume any liquid for 1 hour following ingestion of the Elraglusib Oral Solution. However, it was acceptable to consume a lozenge or hard candy or chew gum after dosing if the subject experienced any issues with the taste of the oral solution. [00611] Elraglusib Injection (10 mg/mL) administered as an IV infusion over 60 minutes (concentration in mg/mL and infusion rate in mL/kg/hour could vary depending on the subject’s body weight). [00612] Subjects fasted overnight (except water) for at least 8 hours before administration of the IV infusion. [00613] Subjects were not to have their post-dose meal for at least 4 hours after the end of the infusion. [00614] The 3.3 mg/kg dose was based on the subject’s Period 1 Day -1 weight (rounded to the nearest 0.1 kg) unless the subject’s weight changed by more than 10%. In that instance, the dose was recalculated using the Day -1 weight (rounded to the nearest 0.1 kg) for Period 2 and/or 3, as indicated. [00615] Results: [00616] PK parameters including AUC, C max , T max , and t 1/2 were analyzed by standard non- compartmental analysis (NCA) methods following each of the elraglusib doses. Log transformed C max and AUC parameters in subjects having adequate PK data following at least 1 of the oral and IV doses were used to assess the relative bioavailability of the oral dose (fed and/or fasted) compared to the IV dose. [00617] Blood samples for PK analysis of elraglusib were to be drawn from all study subjects. [00618] All efforts were made to obtain the PK samples at the scheduled nominal times relative to dosing. PK samples were assayed using validated analytical methods. [00619] Drug Dose, Drug Concentration [00620] Subjects were targeted per protocol to receive 3.3 mg/kg of elraglusib. One subject (106) received only approximately 3% of the targeted dose in the IV infusion treatment after the infusion was interrupted in Period 2 due the adverse event of flushing (grade 2), which was assessed by the investigator as probably related to Elraglusib Injection. Oral doses were administered neat as an oral solution containing 50 mg/mL of elraglusib. The oral doses ranged from 3.6 to 6.3 mL of the oral solution depending on body weight. No additional liquid was allowed orally for at least an hour although subjects could consume a lozenge or hard candy or chew gum after dosing if taste was an issue for the subject.

Subject 106 was not evaluable for Cmax- and AUC-related PK parameters after the IV infusion because of missed sample collections during the IV infusion, but PK parameters associated with the terminal elimination phase were calculable. Subject 114 was evaluable for PK parameters following the IV infusion treatment, but discontinued the study following that treatment so does not provide comparative information for the oral in the fasted or fed states. Both subjects are included in the descriptive statistics for the treatments and PK parameters for which they could be evaluated.

. . and total AUC estimates, with the mean AUC∞ values ranging from 8072 h•ng/mL following the IV administration to 1811 h•ng/mL following oral administration in the fasted state with oral administration in the fed state being intermediate at 5001 h•ng/mL. The 96- hour PK observation window was sufficient to capture between 98% and 99% of the estimated AUC∞ value after each of the 3 treatments. [00628] Figure 42 provides a visual summary of how the various subjects participating in
treatment showed a similar pattern on all 3 treatments. Except for the single instance in 1 subject with the 50.5-hour half-life, the longest half-lives were in the 24-27 hour range, not greatly dissimilar from the majority of the subjects, and not predominantly associated with any particular treatment. [00630] Clearance of elraglusib averaged 0.4268 L/h/kg or 31.14 L/h among the subjects when they received the IV infusion treatment. This clearance value is greater than the nominal adult glomerular filtration rate of 7.2 L/h in humans, but less than nominal renal blood flow (~72 L/h) or nominal hepatic blood flow (~90 L/h), so consistent with renal and/or hepatic clearance mechanisms (Davies B and Morris T. Physiological Parameters in Laboratory Animals and Humans. Pharmaceutical Research 10(7), 1093-1095 (1993) DOI: 10.1023/a:1018943613122). [00631] The mean elraglusib apparent (oral) clearance was 2.608 L/h/kg or 185.7 L/h following administration in the fasted state, but lower (0.9052 L/h/kg or 64.49 L/h) when administered in the fed state, both consistent with incomplete absorption from the gut. The difference in apparent clearances between fasting vs. fed states, without any change in the terminal elimination rate, indicates that, when compared to oral administration while fasting, the high fat breakfast in the fed state facilitates the extent of drug absorption from the gut. [00632] The volume of distribution of elraglusib averaged 11.19 L/kg or 821.8 L among the subjects when they received the IV infusion treatment. This volume is substantially larger than the total body volume, indicating distribution into body tissues, probably at concentrations greater than observed in the plasma in several, or most, tissues. The mean apparent volume of distribution following oral administration was 2- to 5-times larger than the volume of distribution after IV administration, consistent with incomplete of absorption of elraglusib from the gut, as also noted for the apparent clearance. As noted from the apparent clearance values, the apparent volumes of distribution indicate less absorption from the gut occurred following administration under the fasted state than following administration in the fed state. [00633] Relative Bioavailability Comparisons for Elraglusib Treatments [00634] The relative bioavailability of oral administration of elraglusib under fasted and fed states as compared to the absolute (100%) bioavailability following the IV infusion, and the relative bioavailability of the oral dose in the fed state compared to the oral dose in the fasted state are summarized in Table 5-5. Elraglusib administered in the fasted state has an oral bioavailability of approximately 5-11% when calculated using the geometric means of the C max values of IV and oral in the fasted state but is 14-21% when based on the geometric means of the AUClast or AUC∞ values of the individual subjects. Administering elraglusib in the fed state results in an increased oral bioavailability. Elraglusib administered in the fed state results in an oral bioavailability of approximately 19% to 38% when calculated using the geometric means of the Cmax values of IV and oral in the fasted state but is 41% to 63% when based on the geometric means of the AUClast or AUC∞ values of the individual subjects. Administration in the fed state results in an oral bioavailability based on C max that is 2.5- to 5-times that observed when administered in the fasted state and 2.4- to 3.6-times than that observed in the fasted state when based on the AUC metrics.

Thus, total doses of administered elraglusib ranged from approximately 180 mg to 316 mg (with the exception of the incomplete IV infusion dose of approximately 10.1 mg administered to subject 106). Linear regressions of the relative bioavailability of elraglusib based on ratios of Cmax or AUC∞ for the individual subjects are provided in Figure 43 for the IV infusion, Figure 44 for oral dosing in the fasted state, and Figure 45 for oral dosing in the fed state. If the slopes of the relationships in each case are approximately 0.0 (i.e., a nearly horizontal line) then the bioavailability of elraglusib in that setting was approximately uniform over the 2-fold dosing range tested in this study. Confidence intervals (95% CI) are included on the plots to help estimate whether the regression line is statistically different from 0.0 given the limited number of data points available. [00637] The bioavailability linear regressions of Fasted/IV vs. dose for elraglusib (Figure 43) suggest that bioavailability increases with increasing dose. While the slope is statistically different from 0.0 when bioavailability is assessed using Cmax (i.e., the 95% CI for the slope does not contain 0.0), it is not statistically different when comparing using AUC ∞ values. The F Cmax based regression estimates that the oral bioavailability under fasting conditions increases approximately from 4% to 16% as the dose increases from 180 ely hen he se [00639] When the 2 oral dose treatments are compared using linear regression of Fed/Fasted vs. dose (Figure 45) the slopes of the regressions are negative, but not statistically different from 0.0. If the trends are real, they would indicate that the divergence between oral bioavailability in fasted and fed states is greatest when the elraglusib dose is low and decreases at the higher elraglusib doses used in the study. [00640] Dose and Elraglusib Clearance and Volume of Distribution [00641] Elraglusib clearance and apparent clearances were examined using linear regression for a dependence on the elraglusib dose administered. The slopes of the regression relationships for none of the 3 treatments were statistically different from 0.0. However, there was a trend for the slopes following both oral dose treatments to be slightly negative, consistent with the previously noted bioavailability findings that C max and AUC ∞ had regression relationships that increased with increasing dose. The regression line estimates that the apparent clearance after a 320 mg dose is a third to half of the apparent clearance after a 180 mg dose. [00642] Elraglusib volume of distribution and apparent volume of distribution were also examined using linear regression for a dependence on the elraglusib dose administered. The slopes of the regression relationships for none of the 3 treatments were statistically different from 0.0. In addition, there was no apparent trend for the slopes following the oral dose treatments to be either consistently negative or consistently positive. There is little evidence of the volume of distribution or apparent volume of distribution being impacted by the elraglusib dose administered. [00643] This study examined the plasma pharmacokinetics of elraglusib following administration of the drug as an IV infusion of approximately 80 minutes duration, as an oral dose administered in a fasted state, and as an oral dose administered in a fed state (i.e., high fat, high calorie breakfast). The pharmacokinetics objectives of the study included evaluating the pharmacokinetics of elraglusib when administered IV and orally and determining the relative bioavailability of elraglusib when administered orally in a fasted state or when n administered orally in a fed state compared to its bioavailability when administered as an IV infusion. Additionally, the impact of administering the oral dose in a fed state was to be compared to administration in a fasting state. [00644] The study enrolled 18 healthy adult subjects in the 3 period, cross-over study, in which serial PK samples were collected for 96 hours following each of the single dose treatments. All the subjects were pharmacokinetically evaluable in that they had at least one post-dose PK sample collected, although only 16 of the subjects had 1 or more of their 3 concentration-time profiles with enough data available to calculate at least the pharmacokinetic parameters of C max and AUC. Fourteen of the patients had sufficient pharmacokinetic information to make comparisons of drug exposure (i.e., C max and AUC) between at least 2 of the 3 treatments. [00645] Concentrations and Exposures [00646] Elraglusib plasma concentrations declined to near or below the assay LLOQ (0.200 ng/mL) by 96 hours post-dose with all 3 treatments, and the observed AUClast on average accounted for between 98% and 99% of the AUC∞ for all 3 treatments. The concentration-time profiles showed distinct differences between the amplitude and timing of the mean peak concentration, with the greatest exposure and most rapid rise in concentrations associated with the approximately 80-minute IV infusion. The least exposure (i.e., low C max and low AUC) occurred when the oral dose was administered in the fasted state. Ingesting the dose in the fed state resulted in a considerable increase in exposures compared to the oral dose in the fasted state, the 95% CI indicating oral with meal exposures (i.e., fed state) being 2.5- to 5-fold the oral fasted state exposures, but taking the dose with the meal delayed the median time to reach C max by 3 hours. [00647] The terminal elimination half-lives appeared to be similar in most subjects and in the range of approximately 15 to 25 hours for all 3 treatments in the majority of the subjects. However, 2 or 3 of the 16 subjects with evaluable half-lives had elimination half-lives that were approximately a third to a half of the half-lives of the majority of the subjects, suggesting that the study population contained some subjects with a rapid clearance phenotype. This subset of subjects had terminal elimination half-lives ranging from 7 to 11 hours and tended to have low C max and AUC values following oral dosing in the fed or fasted states. They also had among the lowest AUC∞ values following the IV infusion but were in the middle of the pack for Cmax values following the IV infusion. The subset of subjects with short half-lives were among the subjects with the greatest systemic clearance values and smallest volumes of distribution following the IV infusion dosing, consistent with the shorter half-life observation. [00648] Bioavailability Assessments [00649] Relative bioavailability assessments between the 3 treatments compared pairwise confirmed the differences visually apparent from their concentration time profiles. The IV infusion treatment is taken to have 100% bioavailability since the drug is infused directly into the systemic circulation. The oral route of administration is expected to have lower bioavailability either due to incomplete absorption from the gut or due to elimination of drug from the blood stream before the drug can get into the general systemic circulation due to one or more first pass effects. The oral bioavailability of elraglusib was considerably lower when administered in the fasted state than when administered in the fed state suggesting elraglusib preferentially partitions into fatty or lipid materials and can disperse more effectively and transfer across lipid interfaces more readily when administered in the fed state. This interpretation of high lipophilicity is consistent with the observed high volume of distribution, approximately 11 L/kg, observed for elraglusib following administration as an IV infusion. [00650] The relative bioavailability of elraglusib following oral dosing also showed some evidence of dependence on the dose of elraglusib administered, the relative bioavailability increasing as the dose increased. This possibility hints at the presence of a saturable clearance pathway operating in parallel with non-saturable pathways, somewhere in the string of processes between reaching the gut wall and reaching the general circulation, such as a saturable metabolism pathway. This possibility would account for the observation of just a 3% to 11% (Cmax based or AUC∞ based) oral bioavailability at the lowest doses utilized in the study but increasing by approximately 13% with doses approximately 75% higher, also used in the study. However, these differences in relative bioavailability are also associated with different subjects so it is possible that coincidently the higher doses were administered to individuals with a propensity for better absorption of elraglusib. This type of saturable drug elimination pathway would be expected to have a greater effect on C max values than on AUC values since it would be most prominent when drug absorption is occurring most rapidly (i.e., in the time window before reaching and while at Cmax). [00651] The lesser impact of such a saturable drug elimination pathway being less on the elraglusib when administered in the fed state could be related to its higher lipophilicity allowing it to bypass that pathway, either because of location (the later T max when administered with a high fat meal implies more of the absorption occurs further along the gut than when administered while fasting), or because of different uptake mechanisms than can occur with molecules dissolved in or carried along with fat particles. [00652] Interestingly, the relative bioavailability following oral dosing in the fed state reached 91% in one subject (105). This case emphasizes the point that if some saturable pathway is operating to lower the oral bioavailability at low doses, it has less impact as oral doses are increased and will ultimately have a nearly undetectable effect as the relative bioavailability of the oral dose approaches 100% (i.e., producing essentially the same total exposure as if the dose was administered by IV infusion). This study used IV infusion and oral doses of 3.3 mg/kg; previous early phase studies in patient populations have used elraglusib dosed by IV infusion at doses of 1.0 to 15.0 mg/kg, nearly 3- to 5-times the dose utilized in this study, with only minor deviation from dose proportionality (a 15-fold dose change resulting in a 20-fold change in AUC24. If that deviation is real, it is also consistent with the presence of a saturable drug elimination pathway working in parallel with other non-saturable pathways. [00653] Drug Accumulation with Repeat Dosing [00654] Accumulation with repeat dosing was estimated by identifying the extent of carryover from the first dosing interval (i.e., the single dose used in this current study to subsequent dosing intervals 1 x tau, 2 x tau, etc. to n x tau hours when the carryover would be less than 1%). For the IV infusion treatment, Cmax occurs rapidly, and once the infusion is completed concentrations fall rapidly over the next approximately 10 to 12 hours because of a rapid distribution phase. Concentrations decline more than 10-fold over that time interval. Accumulation using a planned twice weekly dosing regimen is predicted to be in the 1% to 5% range and even lower if the adopted dosing interval is once weekly. This increase in concentrations between first dose and steady-state is similar to the precision of the current elraglusib assay and so would likely be undetectable unless first dose and steady-state data from a large number of patients were available. [00655] The oral doses have lower C max values but absorption of the elraglusib from the intestinal tract requires longer than typically used for the elraglusib infusions in this study. When taken with food, the terminal half-life becomes dominant after 18 to 24 hours post- dose, and concentrations are still approximately 10% to 20% of the C max values 24 hours after administration of the first dose. Accumulation, using a planned twice weekly dosing regimen, is predicted to be in the 1% to 10% range and lower if the adopted dosing interval is once weekly. Substantial accumulation with repeated dosing (e.g., exceeding 30%) is unlikely unless dosing intervals of 24 hours or less are utilized. Patients with long elraglusib half-lives (i.e., 20+ hours) will generally show greater accumulation after reaching steady- state than will patients with short half-lives (i.e., 10 hours or less). [00656] Pharmacokinetic Conclusions [00657] Elraglusib is systemically bioavailable when administered orally, with its oral bioavailability being enhanced by 2.5- to 5-fold when administered in a fed state (i.e., with a high fat breakfast). Doses greater than 3.3 mg/kg may show greater oral bioavailability than the approximately 5% to 21% observed when administered in a fasted state and the approximately 19% to 63% when administered in a fed state. [00658] Elraglusib pharmacokinetics show substantial between-subject variability when the dose is administered orally. Concentrations and PK parameter estimates are substantially less variable if dosing is by IV infusion. [00659] Elraglusib pharmacokinetics are in their terminal elimination phase after approximately 24 hours post-dose whether the dose is administered IV or oral. The terminal elimination phase has a half-life in the 15- to 25-hour range in the majority of individuals, although there may be a subset of individuals who clear the drug more rapidly exhibiting a terminal half-life in the 6- to 11-hour range. [00660] Elraglusib has a total body clearance that exceeds the nominal glomerular filtration rate in healthy adults but is consistent with being either renally cleared if there are active secretion mechanisms or metabolically cleared in the liver. The apparent clearance observed after oral dosing appears to be a combination of incomplete absorption and first pass metabolism. Incomplete absorption is likely to play a larger role in the higher apparent clearance observed when dosed in the fasted state. [00661] Elraglusib has a volume of distribution that exceeds body weight by approximately a factor of 11 indicating substantial distribution into tissues. Concentrations in some tissues are likely to substantially exceed plasma concentrations. [00662] Significant accumulation of elraglusib with repeated dosing is unlikely with once or twice weekly dosing regimens. Significant accumulation is likely from first dose to steady state with dosing intervals of 24 hours or less. Example 6 – Preparation and Evaluation of Elraglusib ASDs with Four Different Polymers Prepared by Spray Drying From Acetone:Water Solvent [00663] Prior formulation development work compared micronized elraglusib formulated in both dry and wet granulated tablets as well as a spray-dried dispersion (ASD) in a dry granulated tablet. These formulations were dosed in dog PK Study 3. Based on that study an ASD composition of 1:1 elraglusib:cellulose acetate phthalate (CAP) dosed in a tablet was found to achieve approximately 68% oral bioavailability and nominated as the lead for further development. The lead ASD-tablet composition is shown in Table 6-1.

[00666] To this end, a series of ASD prototypes were successfully prepared and characterized. Lead ASD formulations were selected based on initial biorelevant dissolution and physical state characterization data. These lead ASD formulations were then progressed into tablet formulation evaluations and development stability studies.

[00709] Scanning Electron Microscopy [00710] Scanning electron microscopy (SEM) images were captured using a Phenom Pro in 10 kV high resolution mode. Carbon paper was used as the conductive substrate. A plastic spatula was rolled over a < 100 mg sample then carefully rolled over double-sided adhesive carbon paper on top of the stage to prepare the sample. Three left-handed 45° rotations of the sample holder were used to position the sample approximately 2 mm below the top of the stage for imaging. [00711] Differential Scanning Calorimetry [00712] A modulated differential scanning calorimeter was used in conjunction with a controlled humidity chamber at < 5% relative humidity (RH) to test the glass transition temperature. Samples were prepared in differential scanning calorimetry (DSC) pans and lids. Approximately 5 - 10 mg of sample was weighed into each pan which was placed into the appropriate equilibration chamber for at least 10 hours. Samples were removed from the chamber and the lids were crimped as appropriate based on study design. Samples were reweighed and placed on the DSC autosampler. Samples were then run with the method parameters described in Table 6-12. [00713] Table 6-12.

Elraglusib was soluble up to 4% w/w; however, it was observed to crystallize at room temperature when left at static conditions. [00716] Tests performed with 4% w/w elraglusib, and 4% w/w polymer indicate that HPMCAS-MG, Eudragit® L100, and Eastman cellulose acetate phthalate (CAP) were feasible for preliminary spray drying at a solids loading of 8% w/w, if the solutions were used immediately. The HPMCAS-MG and Eastman CAP samples were visually observed to contain some undissolved solids, which are commonly observed for these polymer types, due to the presence of residual levels of insoluble high molecular weight fractions of polymer. [00717] Prior to ASD prototype manufacture additional solvent and polymer combinations were evaluated to determine which mixtures should undergo further development, and range-find the appropriate elraglusib and polymer loadings that would result in suitable solution stability for a reasonable preliminary spray solution hold-time (NLT 24 h). Samples were prepared according to Table 6-13. [00718] Table 6-13.

These results support spray-drying the 95:5 acetone:water solution with drug substance loading of not more than 2.0% w/w. [00730] The 90:10 acetone water sample was sampled and centrifuged after 24 hours to determine concentration of elraglusib by HPLC as summarized in Table 6-18.

Compression profiles were measured using 8 mm round, flat-faced tooling for both formulations with data presented in Table 6-30 and Table 6-31. The elraglusib:EL100 formulation showed significantly increased compressibility compared to the elraglusib:CAP formulation as shown in Figure 50, which is likely inherent to the polymer structure.

Compression of the unit dose targeting at compression pressure of 4,000 psi was performed using a 9.5 x 21.0 mm plain-faced modified oval tooling. [00770] Physical characterization testing was performed on the tablet prototypes. Tablet characterization results are shown in Table 6-33.

[00774] Tablets were also evaluated for appearance, water content, assay, and related substances as summarized in Table 6-34. [00775] Table 6-34.

Sponsor-provided information indicates that RRT 1.21 related substance is the elraglusib anhydride analog. [00776] Dissolution was measured on both ASD formulation lots and compared to previous elraglusib:CAP prototypes as shown in Figure 52. The tablet elraglusib:CAP prototype (35044-052-CAP-B) was comparable to previous data generated for the large-scale CAP tablet lot 35044-033. However, the elraglusib:EL100 tablet prototype (35044-052-L100-B) h p e ( ta re [00777] CONCLUSIONS [00778] The solubility of elraglusib in commercially viable spray-drying solvents was successfully evaluated with and without the inclusion of various polymers. Switching solvents from THF to acetone reduced drug substance solubility, however, elraglusib was still soluble in the presence of dispersion polymers at commercially relevant spray solution weight-by-weight percents in acetone:water mixtures. [00779] Micelle partition coefficients were experimentally determined for elraglusib to inform in vitro non- sink biorelevant dissolution testing, and in vivo performance. This pre- formulation knowledge was leveraged to manufacture spray-dried dispersions of elraglusib for subsequent characterization. [00780] Two ASD prototypes were identified as leads - 50:50 elraglusib:CAP and 50:50 elraglusib:EL100. These were successfully dry granulated, final blended, and pressed into 250 mg strength tablets. The tablets were characterized. The elraglusib:CAP ASD tablets d :CAP ta es, w mpared to [ [ ablets n tability study will evaluate changes, if any, to product quality over time under the following conditions: storage (25°C/60%RH) and accelerated (40°C/75%RH). [00783] Elraglusib ASD Tablets, 250mg, were packaged in 5-count configurations. The packaging for the 5-count configuration was in 60 cc, white HDPE plastic round packer bottle (33/400) closed with a 33 mm white child resistant polypropylene cap with activated heat induction seal foil inner foam liner and 1-gram desiccant sachet. The packaged active tablet product was stored at 25°C/60%RH, and 40°C/75%RH. [00784] 3 Month tablet samples were pulled and analyzed for appearance, assay and related substances, and sink dissolution. [00785] At 3 months, appearance remained unchanged for both formulations and all conditions. [00786] Sink dissolution at the 3 month timepoint was slower for both formulations relative to the initial dissolution profile when compared as normalized to the final percent dissolved. The normalized results are presented based on the initial and 1 month timepoints having percent dissolved greater than 100%. [00787] Sink dissolution for the 3 month timepoint was analyzed using HPLC rather than the previously used in line UV analysis. Additionally, the samples were analyzed using a standard prepared in 6% CTAB and a separate standard prepared in ACN. This was performed to evaluate the hypothesis that the API standard in CTAB was not fully dissolved and at least partially responsible for the higher than 100% dissolved results that were collected at initial and 1 month timepoints. The CTAB standard was observed to have a low response relative to the ACN standard and to precipitate over time. During the 3 month analysis it was monitored closely and injected soon after preparation to ensure it was dissolved during analysis. The data presented here is based on the CTAB standard, which closely matched the ACN standard and did not result in greater than 100% dissolved like was observed in previous timepoints. [00788] The 3 month assay and related substances results for the Eastman CAP tablets were comparable to initial results. The 3 month Eudragit® L100 tablets results were aligned with the initial result (97%). [00789] The impurity profile of both tablet samples at 3 months stored at 25C/60%RH and 40C/75%RH was in line with previous data generated at T=0. [00790] The sample preparation for the tablets was updated to include a 30 min shake in water to facilitate complete disintegration of the tablets. The samples were also placed on a shaker and sonicated after diluent was added to approximately 75% fill. These updates to the sample preparation appear to be more robust for stability samples and are recommended for future testing. [00791] Tablet Formulation Optimization [00792] Prototype Tablet Manufacture [00793] Prototype tablets were manufactured based on the formulation compositions included in Table 6-35. The previous formulation is included for reference. The goal of the tablet optimization was to minimize tablet weight while increasing processing robustness. Two composition tables are included for each prototype, the first is in wt% and the second is in mg/tablet.

A summary of this data is presented in Figure 59. All formulations had very good compactability at reasonable pressures.

The tablets were significantly slower than the ASD as shown in Figure 61 and Table 6-39.

[00814] In this experiment, the prototype 1 tablets were compared to final blend to determine if the formulation dissolves rapidly after granulation/final blending and prior to compression. See Table 6-40. The final blend dissolved to a higher maximum concentration and had higher concentrations at each timepoint relative to the tablet formulation. This indicates that the compression step in the process is slowing down the dissolution and extent ssels, C120 Ultra Formulation (µg/mL) (µg/mL) (µg/mL) (µg/mL) (µg/mL*mi (µg/mL) (µg/mL) n) 50:509-ING- 41:Eudragit® 42 196 15567 171 NT 196 193 L100 ASD 50:509-ING- 41:Eastman CAP 11 161 11733 93 99 161 166 Tablets 50:509-ING- 41:Eudragit® L100 Prototype 1 48 165 11353 83 101 165 179 Final Blend 50:509-ING- [00816] The experiment also compared the tablet and final blend for prototype 1 to the CAP tablet formulation which has been dosed in-vivo with acceptable performance. The final blend for prototype 1 matched the CAP tablet formulation reasonably well and the prototype 1 tablets were slower to dissolve and dissolved to a lower maximum concentration. [00817] One note for the comparison is that the CAP tablet formulation was only compressed to a tensile strength of 1.4 MPa while the prototype 1 tablets were compressed to a tensile strength of 2.1 MPa. The tensile strength of the tablets is an important attribute for downstream processing if a cosmetic coating is to be applied. [00818] Drug Product Formulations and Performance Optimization [00819] Based on the findings from the prototype 1-3 tablets performance investigation, a second round of tablet formulations were manufactured. The goal of the second round was to increase disintegrant to improve dissolution performance and assess different disintegrants to provide a more robust formulation that is not sensitive to hardness/tensile

All formulations compressed to 1.7 – 1.8 MPa had low friability and are anticipated to be acceptable for downstream processing. [00830] Based on the poor disintegration of prototype 6, 3% extragranular disintegrant was added to the formulation for evaluation in dissolution (prototype 7 – composition presented in Table 6-41 above). The intent of this evaluation was to add disintegrant to break the tablet apart to see if the commingling of the disintegrant with ASD had a positive impact on dissolution. This formulation was also intentionally manufactured at a tensile strength of 1.5 MPa to gather friability data and evaluate performance.

Prototype 7 formulation had performance like the first round of prototype formulations and prototype 5 was slow to dissolve.

All sub-lots were deemed to be similar by SEM and PXRD and were combined by bag blending to generate a single lot of BBS0002-028 for further characterization and downstream processing. [00843] The composite ASD (Lot BBS0002-028) has a Tg of 112.3 ± 0.1 C with no indication of phase separation or crystallization. This is slightly higher than the Tg measured for BBS0002-005 at 107.4C (Test Ref.

Sieve analysis was performed on the granulation to determine the particle size distribution. Results indicate nearly half of the granules are above 425 um in size (47.0%). Minimum fines (< 15%) were observed. Data from the analysis can be found below in Figure 56. [00854] After batch factor adjustment and final blending, a 50 g sample of the final blend was collected for Flodex, bulk/tap density, and CTC profiling. Ultimately the final blend was produced in an overall 83.3% yield (940.63 g) and total accountable yield of 93.3%. No observable process issues were encountered during the dry granulation process. [00855] Average (n = 3) bulk and tap density values were measured for both the intragranular and final blend in-process samples.

Values of 18 and 16 were determined for the intragranular and final blend, respectfully. The minimal change in Flow index could be due to inherent cohesiveness of the powder blend before and after granulation (Table 8-4). [00858] Table 8-4.

The IG blend shows higher tabletability and compactability relative to the FB, as interparticulate binding sites were removed during the roller compaction process. Compressibility of both the IG and FB are comparable, indicating dry granulation had minimal effect on the blends ability to reduce in volume as a result of applied pressure. [00860] Collectively all data collected on the intragranular blend, granules, and final blend indicate minimal process refinement is necessary: 2 kN/cm roll force, 1.0 mm screen size, and the parameters listed in Table 8-2 are suitable for scale-up.
