[0027] Somatostatin (SST), also known as somatotropin release inhibiting factor (SRIF) was initially isolated as a 14- aminoacid peptide fromovine hypothalamii (Brazeauet al., Science179, 77‑79, 1973). AnN-terminal extended28-amino acid peptide with similar biological activity to 14-amino acid somatostatin was subsequently isolated (Pradayrol et, al., FEESLetters, 109, 55‑58, 1980;Eschet al., Proc.Natl. Acad.Sci. USA, 77, 6827‑6831, 1980). SST is a regulatory peptide produced by several cell types in response to other neuropeptides, neurotransmitters, hormones, cytokines, and growth factors.SSTacts throughboth endocrineandparacrine pathways toaffect its target cells.Manyof theseeffects are related to the inhibitionof secretionof other hormones,most notablygrowthhormone (GH). Theyareproducedbyawidevariety of cell types in the central nervous sstem (CNS) and gut, and have multiple functions including modulation of secretion of growth hormone (GH), insulin, glucagon, as well as many other hormones that are anti-proliferative.

[0028] Thesepleotropic actions of somatostatins aremediatedby six somatostatin receptor proteins (SSTR1,SSTR2a, SSTR2b, SSTR3, SSTR4, SSTR5). The six somatostatin receptor proteins are encoded by five different somatostatin receptor genes (ReisineandBell, EndocrRev. 16, 427‑442, 1995;Patel andSrikant, TrendsEndocrinolMetab8, 398‑405, 1997). All the receptors are members of the class-A subgroup of the G protein-coupled receptor (GPCR) superfamily. SST2A receptor is the most widely expressed subtype in human tumors and is the dominant receptor by which GH secretion is suppressed. Unless otherwise stated, the term SSTR2 means SSTR2a.

[0029] It is possible to selectively modulate any one of the somatostatin receptor subtypes, or combination thereof. In some embodiments, selectively modulating any one of the somatostatin receptor subtypes relative to the other soma- tostatin receptor subtypes, or combination thereof, is useful in a variety of clinical applications. In some embodiments, selectivelymodulating any one of the somatostatin receptor subtypes relative to the other somatostatin receptor subtypes reduces unwanted side effects in a variety of clinical applications.

[0030] For example, modulation of SSTR2 activity mediates the inhibition of growth hormone (GH) release from the anterior pituitary and glucagon release from pancreas. SSTR2 is also implicated in many other biological functions such as, but not limited to, cell proliferation, nociception, inflammation, and angiogenesis. In some embodiments, a selective SSTR2modulator is used in the treatment of acromegaly, gut neuroendocrine tumors, pain, neuropathies, nephropathies, and inflammation, as well as retinopathies resulting from aberrant blood vessel growth. In some other embodiments, a selective SSTR2modulator is used in the treatment of arthritis, pain, cancer, inflammatory bowel disease, irritable bowel syndrome, Crohn’s disease, Cushing’s disease, acute lung injury, acute respiratory distress syndrome, and ophthalmic disorders such as age-related macular degeneration (AMD), diabetic retinopathy, diabetic macular edema, and Graves ophthalmology, among others.

[0031] In some embodiments, SSTR3 agonists inhibit insulin secretion. In someembodiments, SSTR4 agonists exhibit anti-inflammatory and anti-nociceptive effects. In some embodiments, SSTR5 agonists inhibit insulin secretion. In addition, SSTR5 has also been implicated to modulate the release of growth hormone.

[0032] Somatostatin peptide and its receptor subtypes are also widely expressed in the brain and disruption or diminishment of their activity is potentially involved in several psychiatric and neurodegenerative diseases. For example, concentrations of somatostatin in the cebrebral cortex and hippocampus are reduced in schizophrenics and one of the most consistent neuropathologic findings in this patient group is a deficit in cortical inhibitory interneurons expressing 5 EP 4 635 497 A2 5 10 15 20 25 30 35 40 45 50 55 somatostatin. Somatostatin is also highly expressed in brain regions associated with seizures and has also been implicated as having an important role in epilepsy. Somatostatin levels are diminshed in the hippocampi of Alzheimer’s and Parkinson’s patients, suggesting that restoration of its signaling as a potential drug target for neurodegeneration.

[0033] In one aspect, the compound 3‑[4‑(4-amino-piperidin‑1-yl)‑3‑(3,5-difluoro-phenyl)‑quinolin‑6-yl]‑2-hydroxy- benzonitrile monohydrochloride, or solvate thereof, is a selective nonpeptide SST2 biased agonist that is amenable to oral administration to a mammal in need of treatment with a somatostatin modulator.

[0034] In some embodiments, the somatostatin receptor modulator described herein has utility over a wide range of therapeutic applications. In some embodiments, the somatostatin receptor modulator described herein is used in the treatment of a variety of diseases or conditions such as, but not limited to acromegaly, neuroendocrine tumors, retinopathies and other ophthalmic disorders, neuropathy, nephropathy, respiratory diseases, cancers, pain, neurode- generative diseases, inflammatory diseases, as well as psychiatric and neurodegenerative disorders. In some embodi- ments, the somatostatin receptor modulator described herein is used in the treatment of acromegaly, neuroendocrine tumors, or both in amammal. In some embodiments, the somatostatin receptor modulator described herein is used in the treatment of acromegaly in a mammal. In some embodiments, the somatostatin receptor modulator described herein is used in the treatment of neuroendocrine tumors.

In some embodiments, Compound A is used to treat neuroendocrine tumors.

[0040] In someembodiments, the free base formofCompoundA is incorporated into the formulations described herein. 6 EP 4 635 497 A2 5 10 15 20 25 30 35 40 45 50 55 In some embodiments, Compound A is incorporated into the formulations described herein as a pharmaceutically acceptable salt. In some embodiments, Compound A is incorporated into the formulations described herein as a pharmaceutically acceptable solvate.

[0041] "Pharmaceutically acceptable," as used herein, refers a material, such as a carrier or diluent, which does not abrogate thebiological activity or propertiesof thecompound, and is relatively nontoxic, i.e., thematerial is administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained.

[0042] The term "pharmaceutically acceptable salt" refers to a form of a therapeutically active agent that consists of a cationic form of the therapeutically active agent in combination with a suitable anion, or in alternative embodiments, an anionic form of the therapeutically active agent in combination with a suitable cation. Handbook of Pharmaceutical Salts: Properties, Selection and Use. International Union of Pure and Applied Chemistry, Wiley-VCH 2002. S.M. Berge, L.D. Bighley, D.C. Monkhouse, J. Pharm. Sci. 1977, 66, 1‑19. P. H. Stahl and C. G. Wermuth, editors, Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim / Zirich: Wiley-VCH / VHCA, 2002. Pharmaceutical salts typically are more soluble and more rapidly soluble in stomach and intestinal juices than non-ionic species and so are useful in solid dosage forms. Furthermore, because their solubility often is a function of pH, selective dissolution in one or anotherpart of thedigestive tract ispossibleand thiscapability canbemanipulatedasoneaspectof delayedandsustained release behaviours. Also, because the saltforming molecule can be in equilibrium with a neutral form, passage through biological membranes can be adjusted.

[0048] It should be understood that a reference to a pharmaceutically acceptable salt includes the solvent addition forms. In some embodiments, solvates contain either stoichiometric or nonstoichiometric amounts of a solvent, and are 7 EP 4 635 497 A2 5 10 15 20 25 30 35 40 45 50 55 formedduring theprocessof crystallizationwithpharmaceutically acceptable solvents suchaswater, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of compounds described herein are conveniently prepared or formed during the processes described herein. In addition, the compounds provided herein optionally exist in unsolvated as well as solvated forms.

[0049] Therapeutic agents that are administrable to mammals, such as humans, must be prepared by following regulatory guidelines. Such government regulated guidelines are referred to as Good Manufacturing Practice (GMP). GMPguidelines outline acceptable contamination levels of active therapeutic agents, such as, for example, the amount of residual solvent in the final product. Preferred solvents are those that are suitable for use in GMP facilities and consistent with industrial safety concerns. Categories of solvents are defined in, for example, the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), "Impurities: Guidelines for Residual Solvents, Q3C(R3), (November 2005).

[0050] Solventsare categorized into threeclasses.Class1solventsare toxicandare tobeavoided.Class2solventsare solvents to be limited in use during the manufacture of the therapeutic agent. Class 3 solvents are solvents with low toxic potential and of lower risk to human health. Data for Class 3 solvents indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies.

[0051] Class 1 solvents, which are to be avoided, include: benzene; carbon tetrachloride; 1,2-dichloroethane; 1,1- dichloroethene; and 1,1,1-trichloroethane.

[0052] Examples of Class 2 solvents are: acetonitrile, chlorobenzene, chloroform, cyclohexane, 1,2-dichloroethene, dichloromethane, 1,2-dimethoxyethane, N,N-dimethylacetamide, N,N-dimethylformamide, 1,4-dioxane, 2-ethoxyetha- nol, ethyleneglycol, formamide, hexane, methanol, 2-methoxyethanol, methylbutyl ketone, methylcyclohexane, N- methylpyrrolidine, nitromethane, pyridine, sulfolane, tetralin, toluene, 1,1,2-trichloroethene and xylene.

[0053] Class 3 solvents, which possess low toxicity, include: acetic acid, acetone, anisole, 1-butanol, 2-butanol, butyl acetate, tert-butylmethyl ether (MTBE), cumene, dimethyl sulfoxide, ethanol, ethyl acetate, ethyl ether, ethyl formate, formic acid, heptane, isobutyl acetate, isopropyl acetate, methyl acetate, 3-methyl‑1-butanol, methylethyl ketone, methylisobutyl ketone, 2-methyl‑1-propanol, pentane, 1-pentanol, 1-propanol, 2-propanol, propyl acetate, and tetrahy- drofuran.

[0054] Residual solvents in active pharmaceutical ingredients (APIs) originate from the manufacture of API. In most cases, the solvents are not completely removed by practical manufacturing techniques. Appropriate selection of the solvent for the synthesis of APIs may enhance the yield, or determine characteristics such as crystal form, purity, and solubility. Therefore, the solvent is a critical parameter in the synthetic process.

[0055] In some embodiments, compositions comprising Compound A-HCl include a residual amount of an organic solvent(s). In some embodiments, compositions comprisingCompoundA-HCl comprise a residual amount of aClass 2 or Class 3 solvent. In some embodiments, compositions comprising Compound A-HCl comprise a residual amount of a solvent selected from ethyl acetate, isopropyl acetate, tert-butylmethylether, heptane, isopropanol, methanol, acetone, dimethylformamide, tetrahydrofuran, 1,4-dioxane, 2-methyltetrahydrofuran, toluene, and ethanol.

[0076] The amorphous state for most small molecule drugs is thermodynamically unstable and, unless the glass transition temperature (Tg) is sufficientlyhigh, alsokineticallyunstable.However, theamorphousstatecanbestabilizedby dilution of the drug in an excipient matrix. When an amorphous molecule is dispersed in a high Tg matrix, low molecular mobility provides a diffusion barrier which inhibits molecular mobility that is required for phase separation upon storage. Phase separation into drug rich domains is the precursor to forming crystal nuclei and eventually widespread crystal- lization which results in a lost solubility advantage. In some embodiments, pharmaceutically acceptable polymers for use in preparing spray-dried solid dispersions are polymerswith ahighTg. In caseswhen theactivepharmaceutical ingredient (API) and excipient are not thermodynamically miscible with one another in the solid state, the spray-dried dispersion (SDD) is formulated such that the resulting Tg of the mixture, including absorbed water, is at least 10 °C to 20 °C greater than typical storage conditions. Further, considerationsmust bemade with respect to water uptake during storage, either through selection of a non-hygroscopic polymer or packaging configuration, as adsorbed water will plasticize the dispersion and lower the Tg.

[0125] The followingexamplesareprovided for illustrativepurposesonlyandnot to limit thescopeof theclaimsprovided herein. Example 1: Oral Capsules

[0127] A representative description of the manufacturing process for the hot melt granulation capsules is as follows: Stage 1: High ShearWet Granulation: Melt the Vitamin E Polyethylene Glycol Succinate (TPGS). Compound A-HCl, mannitol, microcrystalline cellulose, croscarmellose sodium and silicon dioxide are charged into a high shear wet granulator and mixed. The melted Vitamin E TPGS is sprayed onto the granulation components. Stage 2: Milling: The wet granulation is milled through a screening mill using an appropriately sized screen. Stage 3: Blending: The sodium stearyl fumarate is sieved using an appropriately sized screen. Themilled granulation is charged into the diffusion mixer (tumble) along with the sodium stearyl fumarate and blended. Stage 4: Encapsulation: The 10 mg capsules were automatically encapsulated in Size 2 gelatin capsules. Example 2: Spray-Dried Solid Dispersions

[0128] Spray-dried solid dispersions were prepared with 15% by weight Compound A-HCl: 15 / 85 Compound A- HCl / HPMCAS-M and 15 / 85 Compound A-HCl / PVP VA64 formulations. The manufactures were completed using the BLD‑150, the Bend Lab Dryer with 150 kg / hr drying gas capacity. The parameters varied were solution solids loading for the HPMCAS-MSDD formulation to help reduce nozzle bearding, and dryer outlet temperature for the PVP VA64 SDD to de-risk fluctuations thatmay occur during clinicalmanufacturing. The original process parameter screening plan specified manufacturing the decreased dryer outlet temperature condition with a larger orifice nozzle to produce larger particles, however based on the results of the first spray it was determined that the atomization pressure needed to achieve the desired solution flow rate would have been too low to fully atomize the solution with the larger orifice. As dryer outlet temperature tends to havemore variability than solution flow rate, the parameter screenwas shifted to focus on de-risking the dryer outlet temperature alone while ensuring fully atomized droplets. Dryer outlet temperature variation could affect residual solvent levels in the SDDs, which can affect physical and chemical stability. All sprays were completed successfully with good yields, and indicate a robust processing space for both formulations. 15 / 85 Compound A HPMCAS-M SDD Formulation Manufacturing Details

[0129] Three sub batches of 15 / 85 Compound A-HCl / HPMCAS-M SDDs were sprayed to explore the manufacture processing space and prepare for clinical trial manufacturing. A sub batch was sprayed first at 10 wt% solids, and significant nozzle bearding that appeared to affect the spray plume was observed after about 45 minutes on solution.

[0130] Thesolutionwasdiluted to 8wt%,andasubbatchwasmanufacturedwithadurationof 1 hour toensurebearding was reduced. A very small amount of bearding was observed during this batch after about 50 minutes on solution, but did not appear to affect the atomization plume and the 8 wt% solids loading was selected.

[0131] Coolingwater at 2GPMand approximately 7 °Cwas run through the spray dryer lid throughout all sprays to keep the lid cool and prevent sticking and browning. No significant lid buildup or browning was seen throughout manufacturing. No cleaning was performed between sprays, and all sprays were completed from one solution with additional solvent added prior to manufacturing batches 2A and 2C. A summary of the manufacturing parameters used for all three sub batches is shown in Table 2. 16 EP 4 635 497 A2 5 10 15 20 25 30 35 40 45 50 55 Table 2.

[0132] Process parameter screening sprays and an FPN demonstration batch were also completed for the 15 / 85 Compound A-HCl / PVP VA64 SDD formulation. The dryer outlet temperature was varied to de-risk process parameter variability to prepare for clinical trial manufacturing.

[0133] The process space was constrained by a maximum dryer outlet temperature, the dryer outlet temperature, and theminimumdesired solution flow rate.Amaximum inlet temperatureof 160 °Cwasspecified toavoid stickingor browning ofSDDon thespraydryer lid, and theminimumflow ratewassetat 100g / min toensuresufficient throughput. Theminimum and maximum dryer outlet temperatures were chosen to be 40 °C and 65 °C respectively to ensure adequate particle drying and that the dryer outlet temperature will not be above the wet particle Tg.

[0134] The process parameter screening sprays for the PVP VA64 formulation explored the manufacturing space by varying the dryer outlet temperature. This allowed investigation of the effect of dryer relative saturation on particle residual solvent content, morphology, density, and stability.

[0135] Cooling water was run at 2 GPM and approximately 7 °C throughout all sprays to prevent lid buildup and browning, and neither were noted. No nozzle bearding was observed throughout all three manufactures. All sprays were completed from one solution. The manufacturing details of each sub batch are summarized in Table 3.

SDD Characterization

[0136] Particle Properties: The particle size distribution and bulk and tapped densities were measured for each batch of Compound A-HCl SDD. TheHPMCAS-MSDDs have larger particle sizes, which is expected because theHPMCAS-M solution is more viscous than the PVP VA64 solution which leads to larger droplets for a given nozzle configuration. The increased solids loading in solution of lot 2B led to larger particles than batches 2A and 2C, which is also due to the higher viscosity of the spray solution. The particle size distributions of all PVPVA‑64 batches are similar, as expected.

[0137] Thebulk and tappeddensities of 2Aand2Care similar, while batch 2Bhas a slightly lower density potentially due to the larger particles. The bulk and tapped densities of all PVPVA‑64 batches are similar, indicating a robust processwith respect to the dryer outlet temperature effects on powder properties.

[0138] Residual Solvent and Water Content: The residual methanol and water of the six SDDsweremeasured using GCandKF respectively. All SDDscontained residualmethanol below the ICHguideline of 0.3wt%after secondary drying, suggesting adequate drying at 40 °C / 15%RH.

[0139] Morphology by SEM: The particle morphology of all six SDDs was evaluated via SEM. Each SDD showed typical morphology with no evidence of irregular particles suggesting adequate atomization for all conditions tested. The HPMCAS-M particles were primarily collapsed spheres while the PVP VA64 SDDs contain a larger fraction of spherical particles.

[0140] Crystallinity by PXRD:All six SDDswere evaluated for crystallinity using PXRD. All SDDswere amorphous by PXRD as evident in the absence of sharp diffraction peaks.

[0141] Thermal Characteristics by DSC: All six SDDs were characterized by modulated DSC. The results are tabulated in Table 4. Themanufactured SDDs were all amorphous and homogenous by DSC as evident by the presence of a single glass transition in the reversing heat signal. Neither formulation shows signs of crystallization after the Tg suggesting low propensity for crystallization of Compound A at those temperatures for both formulations. Furthermore, both formulationsshowedhighTg relative toambient temperaturessuggesting lowphysical stability risks indryconditions. Packaging to minimize humidity will be necessary for the PVP VA64 formulation. Table 4. Tabulated thermal characteristics of the six batches as measured by DSC.

[0142] PhysicalStability observations:PVPVA64SDDappeared todeliquesceuponstoragewith crystals observedat 3 months (40 °C / 75%RHopen). Storagewith desiccant is recommended.HPMCAS-MSDDwasphysically stable through6 18 EP 4 635 497 A2 5 10 15 20 25 30 35 40 45 50 55 months at 40 °C / 75%RH open.

[0143] Chemical Stability observations: Possible acid catalyzed degradation in theHPMCAS-M formulation on stability. Some degradation in the PVP VA64 formulation as well, but not as significant as the HPMCAS-MSDD. Packaging will be required for the PVPVA SDD which will be driven by physical stability concerns.

[0144] The 15% by weight Compound A / PVP VA64 was selected as the lead SDD formulation. 12-month stability: 15% Compound A-HCl / PVP-VA64 SDD

[0145] 12-month SDD sampleswere held at 5 °C, 25 °C / 60%RH, and 40 °C / 75%RHwith desiccant. Samples for water analysis by Karl Fisher titration were prepared and analyzed immediately; the remaining samples were vacuum desiccated overnight to remove residual moisture and preserve the physical state of SDD’s for further characterization. A list of the analytical tests performed for characterization included: appearance, water content by Karl Fisher titration, Powder x-ray diffraction (PXRD), scanning electronmicroscopy (SEM), thermal characterizationbymodulateddifferential scanning calorimetry (mDSC), dissolution performance bymicro-centrifuge (MCT) test, assay and related substances by HPLC.

[0146] Conclusion fromPXRDanalysis on the12-monthSDDstability samples: Therewasnoevidenceof crystallinity in samples stored at 12 months at each of the stability conditions.

[0147] Conclusion from SEM analysis on the 12-month SDD stability samples: No particle fusion was observed across all stability conditions at 12 month. There was no evidence of crystallinity in samples stored at 12 months at each of the stability conditions.

[0148] Conclusion from SEManalysis on the 12-month SDD stability samples: No particle fusion is observed across all stability conditions at 12 months. There was no evidence of crystallinity in samples stored at 12 months at each of the stability conditions.

[0149] Conclusions from mDSC analysis on the 12-month SDD stability samples: Repeated analysis of the 12 month SDDsampleheldat 5 °Caffordsnon-reproducible thermograms, the cause for this result is not knownat this time.The5 °C sample was determined to be physically stable by all other characterization techniques. The 12month SDD samples held at 25 °C / 60%RH and 40 °C / 75%RH showed a single, reproducible Tg at 124‑125 °C, supporting the conclusion that the SDD is stable after 12 months of storage with desiccant at these conditions.

[0150] Conclusion from MCT dissolution analysis on the 12-month SDD stability samples: Non-sink dissolution performance of the 12 month stability samples is consistent with the initial (t0) sample stored at ‑20 °C. 35 / 65 Compound A-HCl / PVP VA64 SDD Formulation Manufacturing Details

[0156] A representative non-limiting description of the manufacturing process for the SDD tablets is as follows: Stage 1: Spray Drying: Compound A-HCl and copovidone are dissolved in MeOH. The solution spray-dried. Spray- dried dispersion (Compound A-HCl SDD) is collected. Stage 2: Roller Compaction: Granulation blend consisting of Compound A-HCl SDD, filler(s), disintegrant(s), glidant(s), and lubricant(s) are blended. In some embodiments, granulation blend consisting of Compound A-HCl SDD,mannitol,microcrystallinecellulose, crospovidone, colloidal silicondioxidearepreparedandblended.The intra- granular portion of the magnesium stearate is screened and added to the granulation blend. The resulting blend is blended. Granulation blend is charged into hopper of the roller compaction and compacted into ribbons. The ribbons are passed through mesh screen using in-line oscillating mill to break up the ribbons and mill into granules.

[0157] In some embodiments, the granulation blend comprises about 20% to about 35% (w / w of the final tablet weight) CompoundA-HClSDD. In someembodiments, the granulationblend comprisesabout 21%, about 22%, about 28%,29%, about 33%, about 34% (w / w of the final tablet weight) Compound A-HCl SDD. In some embodiments, the Compound A- HCl SDD comprises a 15 / 85 CompoundA-HCl / HPMCAS-M, 15 / 85 CompoundA-HCl / PVPVA64, or 35 / 65 CompoundA- HCl / PVPVA 64 SDD.

[0158] Stage 3: Blending: The intra-granular material is mixed with the extragranular excipients. Extragranular excipients compriseoneormoreexcipients selected from: fillers, disintegrants, glidants, and lubricants. Theextragranular components include microcrystalline cellulose, crospovidone, colloidal silicon dioxide. The extragranular lubricant, magnesium stearate, is sieved using an appropriately sized screen, then added to the blend and mixed.

[0159] Stage 4: Compression: The final blend is compressed into tablets.

[0160] Stage 5: Pan-Coating: Film coating suspension of Opadry White 03K18416.is prepared in purified water, and tablets are coated with Opadry White 03K18416 in a perforated coating pan. Example 4: Evaluation of Formulation Performance in Dogs Study Designs

[0161] Evaluated two conditions* in the dog: +Pg pretreatment (mimics human fasted stomach, pH 1‑2) and ‑Pg pretreatment (mimics humans taking PPIs or antacids, pH 3‑5). (*: 1-week washout between each condition; Pg=penta- gastrin.) Compound A-HCl Solution

[0166] As shown in Table 15 and Figure 2, the HMG capsule formulations performed poorly in dogs not pretreated with pentagastrin, whereas the spray-dried dispersions tablets performed better; For HMG capsule formulation, AUC without pentagastrin was only 11% of the AUC with pentagastrin (98.2 ng*hr / mL compared to 917 ng*hr / mL). In comparison, the AUC for the PVPVA SDD tablet formulations without pentagastrin was 185% and 124% of with pentagastrin condition, respectively. These data show that PVPVASDD tablet formulations are superior under high gastric pH environment (e.g., as would be in subjects that are are taking PPI or antacids). Table 16.

[0167] The study was conducted in up to 3 cohorts, each with a specific primary objective:

[0168] Cohort 1: To characterize performance of 10mg tablets prepared by spray-dried dispersion (SDD) of Compound A-HCl salt.

[0169] Cohort 2: Toevaluate the relative bioavailability of 10mgSDD tablets compared to theCompoundA-HCl hotmelt granulation (HMG) formulation, 10 mg capsules. To determine the effect of timing of food administration on pharmaco- kinetics of low dose of the 10 mg SDD tablets.

[0170] Cohort 3: To determine the effect of timing of food administration on pharmacokinetics of SDD tablets and dose proportionality in doses higher than 20 mg. To determine the optimal dosing regimen that results in adequate systemic exposure with short post-dose fasting duration. Study Design:

[0171] Up to thirty-six (36) healthymale and female subjects were enrolled. Cohorts 1‑2 consisted of four periods each, and Cohort 3 consisted of three periods. Cohort 1:

[0172] The SDD tablets were evaluated. Up to twelve (12) healthy male and female subjects were enrolled in each cohort. Cohort 1 consisted of 4 periods: In Period 1, subjects were administered a proton-pump inhibitor (lansoprazole, 15 mgBID for 3 days (fromDay ‑3), taken orally at least 30min prior to ameal, once in themorning and once in the evening). On the fourth day (Day 1 of study), fasted subjects will take the last dose of lansoprazole (15 mg) 60 min prior to 20 mg CompoundA (2x10mgof theSDDtablets). InPeriod2, fastedsubjectswereadministered20mgCompoundA (2x10mgof the SDD tablets). In Period 3, fasted subjects were administered 20mgCompound A (2x10mg of the SDD tablets) with a high-fat, high-calorie meal. In Period 4, fasted subjects will take up to 80 mg Compound A (up to 8x10 mg of the SDD tablets). The actual dose was selected based on the pharmacokinetic data from Period 2.

[0173] For Period 1: In the evening before dosing (Day ‑1), subjects were administered their evening dose of 15 mg lansoprazole, providedaneveningmeal at least 30minafter administration of lansoprazole, and thenwere required to fast overnight (≥10hr) onDay ‑1.OnDay1, theywereadministered themorningdose (last dose)of 15mg lansoprazoleat least 60minprior toadministrationofCompoundA (2x10mgSDD tablets). Subjects continued to fast for 2hr afterCompoundA, after which they were allowed to ingest a standard meal.

Test Product, Dose, and Mode of Administration:

[0192] 10 mg tablets (SDD). Multiple tablets were swallowed with water depending on dose specified for a given period / cohort. Reference Therapy, Dose, and Mode of Administration:

[0193] 10 mg HMG capsule formulation served as the reference formulation. Multiple capsules were swallowed with water depending on dose specified for a given period / cohort. Plasma Pharmacokinetic Parameters:

[0194] Blood PK samples were collected to evaluate Compound A plasma concentrations.

[0195] PK parameters were calculated for Compound A and the following are shown in tables below: Area under the plasma concentration curve from 0 to 24 hours (AUC0‑24); Maximum plasma concentration (Cmax); Time to achieve maximum plasma concentration (Tmax); Results

[0196] Results from this clinical trial showed that the co-administration of proton pump inhibitors only had a small effect on the pharmacokinetics observed with the administration of the SDD tablets, shorter fasting times are realized with the SDD tablets and the SDD tablets provide better dose proportional pharmacokinetics.

[0197] Results from Cohort 1 is presented in Table 17. Table 17.

Mean and range are reported for P4 / P2 ratios. All dose administered with overnight fast and 2h post dose fast. Food: high fat meal.

[0198] Cohort 1 (SDD 10 mg x2 under different conditions): the observed exposures with and without PPI are fairly comparable. Cohort 1 (SDD10mg x2 vs. 10mg x 6): Relatively dose proportional increases in exposureswere observed.

[0199] In comparison to theSDD tablets, relatively doseproportional increases in exposureswerenot observedwith the HMG capsules. See Figure 1.

[0201] Cohort 2 (SDD10mgx2 vs.HMGand under different post-dose fasting durations): SDD tablets did not appear to have better exposures than HMG capsules and the two formulations were relatively comparable. For the SDD tablets the AUC0‑24 (a measure of extent of absorption) after a 1 hr post dose fast was decreased to 82% of that obsereved with 2 hr post-dose fast, which is a relatively small decrease in exposure.

[0202] In comparison to the performance of the SDD tablets under different post-dose fasting duration scenarios, the HMG capsules performed poorly under different post-dose fasting duration scenarios in a previously completed clinical study.Pharmacokinetic dataobtainedafter administeringa20mgdose (10mgHMGcapsulex2) in12subjects (N=4male, N=8 Female) is presented in Table 20.

Range is shown for Tmax.

[0203] With the HMG capsule formulations, approximatley 30% loss in extent of absorption was noted with a 1-hour post-dose fasting vs. a 2-hour post-dose fast.

[0204] HMG capsules with a 2h fast was evaluated in Phase 2 clinical studies. A 1 hour fast is more desirable than a 2 hour fast. Only 18% loss of AUC(0‑24) was observed with 1 hour fast compared to a 2 hour fast. SDD 1h fast will be utilized for Phase 3. Importantly, SDD tablets appeared to have better dose proportionality than HMG capsules, allowing for 3.0x dose (i.e., 60 mg) to be administered in Phase 3 clinical studies.
