[0001] PHARMACEUTICAL COMPOSITIONS COMPRISING A PKC INHIBITOR

[0002] RELATED APPLICATION

[0003] This application claims priority to U.S. Provisional Application No. 63 / 520,857 filed on August 21, 2023. The content of this application is hereby incorporated by reference in its entirety.

[0004] BACKGROUND

[0005] Uveal melanoma (UM) is the most common primary intraocular malignant tumor in adults. UM is a type of eye cancer in the uvea of the eye and is traditionally classed as originating in the iris, choroid, and ciliary body, but can also be divided into class I (low metastatic risk) and class II (high metastatic risk). Because there are no lymphatic channels to the uveal tract, metastasis occurs through local extension and / or blood-borne dissemination. The most common site of metastasis for uveal melanoma is the liver; the liver is the first site of metastasis for 80%-90% of ocular melanoma patients. Other common sites of metastasis include the lung, bones, and just beneath the skin (subcutaneous). Approximately 50 percent of patients will develop metastases within 15 years after treatment of the primary tumor, and the liver will be involved 90% of the time.

[0006] International application no. PCT / IB2015 / 055951 (WO 2016 / 020864) discloses a number of potent and selective PKC inhibitors including 3-amino-N-(3-(4-amino-4- methylpiperidin-1-yl)pyridin-2-yl)-6-(3-(trifluoromethyl)pyridin-2-yl)pyrazine-2-carboxamide. This compound is useful in the treatment of certain cancers, including uveal melanoma.

[0007] Provided herein are improved pharmaceutical compositions comprising 3-amino-N- (3-(4-amino-4-methylpiperidin-1-yl)pyridin-2-yl)-6-(3-(trifluoromethyl)pyridin-2-yl)pyrazine-2- carboxamide.

[0016] Definitions

[0017] Listed below are definitions of various terms used herein. These definitions apply to the terms as they are used throughout this specification and claims, unless otherwise limited in specific instances, either individually or as part of a larger group.

[0018] Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art. Generally, the nomenclature used herein and the laboratory procedures in cell culture, molecular genetics, organic chemistry, and peptide chemistry are those well-known and commonly employed in the art.

[0019] As used herein, the articles “a” and “an” refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element. Furthermore, use of the term “including” as well as other forms, such as “include,” “includes,” and “included,” is not limiting.

[0020] As used herein, the term “about” will be understood by persons of ordinary skill in the art and will vary to some extent on the context in which it is used. As used herein when referring to a measurable value such as an amount, a temporal duration, and the like, the term “about” is meant to encompass variations of ±10%, including ±5%, ±1%, and ±0.1% from the specified value, as such variations are appropriate to perform the disclosed methods. For example, a dose of about 300 mg may be understood to mean that the dose may vary between 270 mg and 330 mg.

[0021] As used in the specification and in the claims, the term “comprising” may include the embodiments “consisting of” and “consisting essentially of.” The terms “comprise(s),” “include(s),” “having,” “has,” “may,” “contain(s),” and variants thereof, as used herein, are intended to be open-ended transitional phrases, terms, or words that require the presence of the named ingredients / steps and permit the presence of other ingredients / steps. However, such description should be construed as also describing compositions or processes as “consisting of” and “consisting essentially of” the enumerated compounds, which allows the presence of only the named compounds, along with any pharmaceutically acceptable carriers, and excludes other compounds.

[0022] It should be noted that ratios, concentrations, amounts, and other numerical data may be expressed herein in a range format. It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a dose range of “200 mg to about 600 mg” should be interpreted to include not only the explicitly recited concentration of about 200 mg to about 600 mg, but also include individual dosage (e.g., 250 mg, 400 mg, 550 mg) and the sub-ranges (e.g., 250 mg to 450 mg) within the indicated range. To further illustrate, a tumor size reduction of “30%-50%” should be interpreted to include not only the explicitly recited concentration of about 30% to about 50%, but also include individual percentages (e.g., 35%, 40%, 50%) and the sub-ranges (e.g., 35%-45%) within the indicated range. The term “about” can include ±1%, ±2%, ±3%, ±4%, ±5%, ±6%, ±7%, ±8%, ±9%, or ±10%, of the numerical value(s) being modified. In addition, the phrase “about ‘x’ to ‘y’” includes “about ‘x’ to about ‘y’”.

[0023] As used herein, “metastasis” or “metastatic” means the spread of cancer from its primary site to other places in the body. Cancer cells can break away from a primary tumor, penetrate into lymphatic and blood vessels, circulate through the bloodstream, and grow in a distant focus (metastasize) in normal tissues elsewhere in the body. Metastasis can be local or distant. Metastasis is a sequential process, contingent on tumor cells breaking off from the primary tumor, traveling through the bloodstream, and stopping at a distant site. At the new site, the cells establish a blood supply and can grow to form a life-threatening mass. Both stimulatory and inhibitory molecular pathways within the tumor cell regulate this behavior, and interactions between the tumor cell and host cells in the distant site are also significant.

[0024] As used herein, the term “treating” or “treatment” refers to inhibiting a disease; for example, inhibiting a disease, condition, or disorder in an individual who is experiencing or displaying the pathology or symptomology of the disease, condition, or disorder ( / .e., arresting further development of the pathology and / or symptomology) or ameliorating the disease; for example, ameliorating a disease, condition, or disorder in an individual who is experiencing or displaying the pathology or symptomology of the disease, condition, or disorder ( / .e., reversing the pathology and / or symptomology) such as decreasing the severity of the disease.

[0025] As used herein, the term “prevent” or “prevention” means no disorder or disease development if none had occurred, or no further disorder or disease development if there had already been development of the disorder or disease. Also considered is the ability of one to prevent some or all of the symptoms associated with the disorder or disease.

[0026] As used herein, the term “patient,” “individual,” or “subject” refers to a human or a non-human mammal. Non-human mammals include, for example, livestock and pets, such as ovine, bovine, porcine, canine, feline and marine mammals. Preferably, the patient, subject, or individual is human.

[0027] As used herein, the terms “effective amount,” “pharmaceutically effective amount,” and “therapeutically effective amount” refer to a nontoxic but sufficient amount of an agent to provide the desired biological result. That result may be reduction or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. An appropriate therapeutic amount in any individual case may be determined by one of ordinary skill in the art using routine experimentation. The agent is administered to a subject, either alone or as part of a pharmaceutical composition and either in a single dose or as part of a series of doses.

[0028] As used herein, the term “pharmaceutically acceptable” refers to a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compound, and is relatively non-toxic, i.e. , the material may be 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.

[0029] As used herein, the term “pharmaceutically acceptable salt” refers to derivatives of the disclosed compounds wherein a parent compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts described herein include the conventional non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts discussed herein can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are used. The phrase “pharmaceutically acceptable salt” is not limited to a mono, or 1 :1, salt. For example, “pharmaceutically acceptable salt” also includes bis-salts, such as a bis-hydrochloride salt. Lists of suitable salts are found in Remington’s Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by reference in its entirety.

[0030] As used herein, the term “composition” or “pharmaceutical composition” refers to a mixture of at least one compound or a pharmaceutically acceptable salt thereof, and one or more pharmaceutically acceptable carriers. The pharmaceutical composition facilitates administration of the composition to a patient or subject. Multiple techniques of administering a compound exist in the art including, but not limited to, intravenous, oral, aerosol, parenteral, ophthalmic, pulmonary, and topical administration.

[0031] As used herein, the term “pharmaceutically acceptable carrier” means a pharmaceutically acceptable material, composition or carrier, such as a liquid or solid filler, stabilizer, dispersing agent, suspending agent, diluent, excipient, thickening agent, solvent or encapsulating material, involved in carrying or transporting a compound useful to the patient such that it may perform its intended function. Typically, such constructs are carried or transported from one organ, or portion of the body, to another organ, or portion of the body. Each carrier must be “acceptable” in the sense of being compatible with the other ingredients of the formulation, including the compound disclosed herein, and not injurious to the patient. Some examples of materials that may serve as pharmaceutically acceptable carriers include: sugars, such as lactose, glucose and sucrose; starches, such as corn starch and potato starch; cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients, such as cocoa butter and suppository waxes; oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols, such as propylene glycol; polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; esters, such as ethyl oleate and ethyl laurate; agar; buffering agents, such as magnesium hydroxide and aluminum hydroxide; surface active agents; alginic acid; pyrogen-free water; isotonic saline; Ringer’s solution; ethyl alcohol; phosphate buffer solutions; and other non-toxic compatible substances employed in pharmaceutical formulations.

[0032] As used herein, “pharmaceutically acceptable carrier” also includes any and all coatings, antibacterial and antifungal agents, and absorption delaying agents, and the like that are compatible with the activity of a compound disclosed herein, and are physiologically acceptable to the patient. Supplementary active compounds may also be incorporated into the compositions. The “pharmaceutically acceptable carrier” may further include a pharmaceutically acceptable salt of the compound(s) disclosed herein. Other additional ingredients that may be included in the pharmaceutical compositions are known in the art and described, for example, in Remington’s Pharmaceutical Sciences (Genaro, Ed., Mack Publishing Co., 1985, Easton, PA), which is incorporated herein by reference.

[0033] As used herein, the term “superdisintegrant” refers to substances that facilitate disintegration and decrease the disintegration time. Non limiting examples include crosslinked polyvinyl pyrrolidone (crospovidone), xantham gum, chitin, gellan gum, sodium starch glycolate, croscarmellose sodium, and microcrystalline cellulose. In an embodiment, the superdisintegrant is crospovidone.

[0034] As used herein, the term “binder” refers to chemical compounds that have an adhesive property to promote cohesiveness. Binders are typically polymeric materials that are included into pharmaceutical compositions to allow for an increase in surviving bond formation when exposed to high forces resulting in compacts with adequate mechanical strength, e.g., in a tablet. Non limiting examples include hydroxypropylcellulose, methylcellulose [MC], povidone [PVP], starch, gelatin, resins, and hydroxypropyl cellulose. In an embodiment, the binder is hydroxypropyl cellulose of super low viscosity.

[0035] The term “lubricant,” is used herein to refer to an additive that reduces friction to prevent cracking or breakage of a tablet. Non limiting examples include magnesium stearate, calcium stearate, stearic acid, talc, sodium stearyl fumarate, carrageenan, glyceryl behenate, and sodium lauryl sulfate. In an embodiment, the lubricant is magnesium stearate.

[0036] The term “filler,” as used herein, refers to an inactive substance used to make an active pharmaceutical ingredient, such as Compound 1 , easier to measure. Non limiting examples include microcrystalline cellulose, lactose, mannitol, pre-gelatinized starch, titanium dioxide, glycerin, and dextrin. In an embodiment, the filler is microcrystalline cellulose.

[0037] The term “friability of a tablet,” as used herein, refers to the tendency of a tablet to lose component particles due to abrasion, friction, or mechanical shock.

[0038] The dose amounts (for Compound 1) are expressed as free base equivalent amounts, unless indicated otherwise.

[0341] The Compound 1 crystal form was determined using a Bruker D8 advance X-Ray Diffractometer or equivalent.

[0343] In one aspect, the pharmaceutical composition comprising Compound 1 is an Immediate Release (IR) tablet for oral administration containing Compound 1 provided for in two dosage strengths, 100 mg and 300 mg, referred to herein as: • Compound 1, 100 mg I R Tablets

[0346] Composition of Compound 1 1R Tablets

[0347] The quantitative compositions of the Compound 1 IR Tablets are presented in Table 1. Compound 1, 100 mg I R Tablets and Compound 1 , 300 mg IR Tablets are dose proportional.

[0348] Table 1 : Quantitative Compositions of Compound 1 IR Tablets

[0349] In an embodiment, the quantitative compositions of the Compound 1 IR Tablets are according to Table 1A. Compound 1, 100 mg IR Tablets and Compound 1, 300 mg IR Tablets are dose proportional.

[0350] Table 1A: Quantitative Compositions of Compound 1 IR Tablets

[0351] A screening of superdisintegrants demonstrated that Crospovidone was a better disintegrant than Croscarmellose sodium (CCNa). Tablets composed of Croscarmellose sodium showed a marked increase in disintegration time during storage; whereas tablets composed of Crospovidone did not show any change in disintegration time during storage. Additional feasibility batches were conducted to assess the impact of various binders at different levels on disintegration time. Hydroxypropyl cellulose extra fine particle size grade (HPC EXF), Hydroxypropyl Methyl Cellulose low viscosity grade (Methocel E5 Premium LV) and Hydroxypropyl cellulose super low viscosity (HPC-SL) (see AAPS PharmSciTech 2013 Mar;14(1):151-9) were evaluated. On the basis of disintegration time and processability, HPC-SL was selected as the binder of choice for the Compound 1 IR Tablets.

[0352] Additional feasibility batches were conducted to assess the impact of various surfactants like Sodium lauryl sulfate (SLS) and Poloxamer (Kolliphor P 407) on Compound 1 drug release and found no obvious difference in dissolution between tablets with and without surfactants. Hence It was determined that a surfactant is not needed as a wetting agent in Compound 1 Tablets.

[0353] Additional feasibility batches were conducted to assess the impact of granulation fluid level, Compound 1 particle size and compression force on tablet dissolution.

[0354] Based on the feasibility batches, it was determined that Compound 1 with smaller particle size leads to better tablet properties and a more robust manufacturing process.

[0355] Example 2. Manufacturing of Compound 1 Tablets 100 mg and 300 mg

[0356] In order to develop a manufacturing process for the Compound 1 IR Tablets, a high shear wet granulation was selected. This selection was made based on the projected efficacious high dose necessitating the development of a high drug load formulation. Formulation development focused on selecting the most appropriate super-disintegrant, binder and to determine if a wetting agent was required.

[0357] Manufacturing Formula for Initial Feasibility Development, CCNa with HPC EXF as Binder The first feasibility batch was conducted using the super-disintegrant (CCNa) and binder (HPC EXF), the drug load was fixed at about 67% and SLS was included as a wetting agent.

[0358] Table 2. Manufacturing formula of Compound 1 Tablets 300 mg initial feasibility batch, CCNa and HPC EXF

[0359] * Granulating fluid (%) to dry-mix weight

[0360] Manufacturing Procedure for Initial Feasibility Development, CCNa with HPC EXF as Binder Granulation: Compound 1 , Croscarmellose Sodium, Hydroxypropyl cellulose (EXF), and Sodium lauryl sulfate (SLS) were co-sifted through 20 mesh screen. Sifted materials were loaded into 1 L RMG bowl and dry mixing was performed for 05 minutes. Purified water was added into the mixture by using peristaltic pump at a fixed speed and granulation was performed with the below listed parameters in Table 3.

[0361] Drying and Sizing: Wet granules were charged into Tray Dryer with an inlet temperature of 60°C for 30 minutes. Semi-dried granules were milled through comil FZB-150 using 1.2 mm screen. Semi-dried granules were dried further until the desired LCD was attained. Drying parameters are listed in Table 4.

[0362] Table 3: Wet granulation parameters of initial feasibility batch, CCNa and HPC EXF

[0363] Blending: Microcrystalline Cellulose PH102 and Croscarmellose Sodium were co-sifted through a 30 mesh sieve and blended with dried granules for 10 minutes at 15 rpm using 1 L bin. Lubrication: Magnesium stearate was sifted through a 60 mesh sieve, added to the above blend and mixed for 03 minutes at 15 rpm.

[0364] Table 4: Powder flow characteristics and sieve analysis details of initial feasibility batch, CCNa and HPC EXF Compression: The lubricated blend was compressed into tablets to a target weight of 450 mg using 15.6x7.4 mm oval shaped punches.

[0365] Table 5: Compression parameter of Compound 1 tablets 300 mg, initial feasibility batch, CCNa and HPC EXF

[0366] Observation: A wet granulation feasibility batch with intra and extra granular Croscarmellose sodium was performed. Storage at ambient conditions resulted in a significant increase in disintegration time. This increase in disintegration time was assigned to a molecular interaction between the drug substance and CCNa. Hence, the use of Croscarmellose sodium was discontinued, and further formulation development work focused on the evaluation of Crospovidone and Sodium starch glycolate as suitable disintegrants.

[0367] Evaluation of Crospovidone and Sodium starch glycolate (SSG)

[0368] Two feasibility trial batches were executed with alternative superdisintegrants i.e. , Crospovidone (Polyplasdone XL) and Sodium starch glycolate (Explotab). The disintegration time of these two batches were measured immediately after manufacturing and after storage in ambient conditions.

[0369] Table 6: Manufacturing formula of Compound 1 Tablets 300 mg (Crospovidone vs SSG)

[0370] Granulating fluid (%) to dry-mix weight

[0371] Granulation: Compound 1 , Hydroxypropyl cellulose (EXF), Sodium lauryl sulfate (SLS), and Crospovidone (Polyplasdone XL) I Sodium starch glycolate Type A (Explotab) were co-sifted through a 20 mesh screen. Sifted materials were loaded into a 200 mL Turbula and dry mixing was performed for 15 minutes. As the batch size was low, wet granulation was performed manually with an adequate quantity of water to produce desired granules.

[0372] Blending: Microcrystalline Cellulose PH102 and Crospovidone (Polyplasdone XL) I Sodium starch glycolate Type A (Explotab) were co-sifted through a 30 mesh screen. Sifted materials were loaded along with sized granules into the 0.2 L Turbula bin and blended for 10 minutes at 46 rpm.

[0373] Lubrication: Magnesium stearate was sifted through a 60 mesh sieve, added to the above blend and mixed for 05 minutes at 46 rpm.

[0374] Compression: The lubricated blend was compressed into tablets to a target weight of 450 mg using 16x6.5 mm, capsule shaped punches. Table 7: Compression parameter of Compound 1 tablets 300 mg, disintegrant type selection, Crospovidone vs SSG

[0377] Drug Release Profile, Disintegrant Type Selection, CCNa vs Crospovidone vs SSG Table 9: Dissolution profile of Compound 1 Tablets 300 mg, disintegrant type selection batches, CCNa vs Crospovidone vs SSG

[0378] Conclusion:

[0379] Crospovidone: Granulation and compression parameters were found to be satisfactory.

[0380] Rapid disintegration was observed. Drug release in pH 6.8 phosphate buffer was slightly slower compared to drug release in 0.01 M HCI.

[0381] Sodium starch glycolate: Granulation and compression parameters were found to be satisfactory. Rapid disintegration was observed. Drug release in pH 6.8 phosphate buffer was similar compared to drug release in 0.01 M HCI. Both disintegrants exhibited satisfactory disintegration efficiency compared to croscarmellose sodium prototypes. No change in disintegration was observed upon storage for tablets containing Crospovidone or SSG. Disintegrant Level Optimization Studies, Crospovidone vs Sodium starch glycolate (SSG) In order to optimize the level of super-disintegrant in the Compound 1 Tablets, batches with 2% intra granular and 2% extra granular disintegrant were produced. The dissolution of tablets was relatively slower than the 200 mg Powder in Capsule (PIC) for Compound 1 (i.e., 88% drug release in 5 minutes & 98% drug release in 10 minutes). Hence feasibility batches were executed with 4% w / w intra and 2% w / w extra granular disintegrant to attain a rapid drug release profile.

[0383] Granulating fluid (%) to dry-mix weight Manufacturing Procedure, Disintegrant Level Optimization Batches, Crospovidone vs SSG Granulation: Compound 1 , Hydroxypropyl cellulose (EXF), Sodium lauryl sulfate (SLS), and Crospovidone (Polyplasdone XL) I Sodium starch glycolate Type A (Explotab) were co-sifted through a 20 mesh screen. Sifted materials were loaded into 1 L RMG bowl and dry mixing was performed for 5 minutes. Purified water was added into the mixture by using peristaltic pump at a fixed speed and granulation was performed with the below listed parameters in Table 11.

[0384] Drying and Sizing: Wet granules were charged into a Tray Dryer with an inlet temperature of 60°C for 15 minutes. Semi-dried granules were milled through Comil FZB-150 using 1.2 mm screen. Semi-dried granules were dried further until the LCD reached less than 0.5% w / w at 105°C. Drying parameters are listed in Table 11.

[0385] Table 11 : Wet granulation parameters of disintegrant level optimization batches, Crospovidone vs SSG

[0386] Blending: Microcrystalline Cellulose PH102 and Crospovidone (Polyplasdone XL) I Sodium starch glycolate Type A (Explotab) (SSG) were co-sifted through a 30 mesh screen. Sifted materials were loaded along with sized granules into the 0.2 L Turbula bin and blended for 10 minutes at 46 rpm.

[0387] Lubrication: Magnesium stearate was sifted through a 60 mesh sieve, added to the above blend and mixed for 03 minutes at 46 rpm.

[0388] Compression: The lubricated blend was compressed into tablets to a target weight of 450 mg using 17x6.7 mm, capsule shaped punches. Table 12: Dissolution profile of Compound 1 Tablets 300 mg disintegrant level optimization, Crospovidone vs SSG

[0389] Conclusion: Prototypes of disintegrant level optimizations (i.e., 4% intra and 2% extra granular Crospovidone / SSG) resulted in a satisfactory granulation and tablet properties. No significant difference in drug release was observed between 2% and 4% intra-granular disintegrant for SSG prototypes. Improved drug release profile was observed for 4% intra- granular Crospovidone prototypes than the 2% intra-granular Crospovidone batches in pH 6.8 phosphate buffer. However, drug release profiles were similar for both 2% and 4% intra- granular disintegrant prototypes in 0.01 M HCI (pH 2.0).

[0390] It was observed that the disintegration time of tablets composed of 4% intra and 2% extra granular SSG increased from its initial disintegration time of 1’54”~2’36” minutes to 8’14” minutes after 20 days of room temperature storage. While the change in disintegration time upon storage did not have an impact on dissolution time, it is suspected that the change in disintegration time of the SSG prototypes would lead to a significant change in dissolution time with longer storage times. Therefore, SSG-containing prototypes were abandoned.

[0391] Drug release profiles of feasibility batches with different granulation vehicle levels i.e., 18%, 20%, and 23% w / w water showed that tablet hardness is directly impacting tablet drug release and disintegration time. Low hardness tablets produced using different granulation fluid levels resulted in a very rapid drug release profile (>90% drug released within 10 minutes). Optimum hardness tablets produced using different granulation fluid levels resulted also in a rapid drug release (>90% drug released within 20 minutes). High hardness tablets produced using different granulation fluid levels resulted in a relatively slower drug release profile than for other tablets at lower hardness levels (>90% drug release could be reached only at 60 minutes). However, optimum hardness tablets produced at different granulation fluid levels resulted in a similar drug release. This confirmed that tablet hardness has a higher impact on drug release than the granulation fluid level. Hence, it was critical to identify suitable hardness range before manufacturing.

[0392] Feasibility Batch Manufacturing with Hydroxypropyl Cellulose SL (HPC-SL) as a Binder

[0393] A feasibility batch was executed with HPC-SL as a binder and different concentrations of crospovidone were evaluated mainly to identity an optimum disintegrant concentration (2% vs 3% Crospovidone) that would lead to satisfactory drug release results. Fine grade Compound 1 (Particle size details: D =24.3 p, Dso=83.1 p, Dgo=211 p) was utilized in these feasibility batches, and tablets were compressed at different compression forces to generate tablets with different hardness values (Low, Optimum, and High). Drug release profiles were generated for tablets compressed at different compression forces.

[0395] Manufacturing Procedure for Feasibility batch with HPC-SL as a Binder and Fine Grade Compound 1 (2% vs 3% Crospovidone)

[0396] Granulation: Compound 1 , Microcrystalline Cellulose PH102, Crospovidone (Polyplasdone XL) and Hydroxypropyl Cellulose SL were co-sifted through a 30 mesh screen. Sifted materials were loaded into a 4 L RMG bowl and dry mixing was performed for 10 minutes. Drying and Sizing: Wet granules were charged into a Tray Dryer with an inlet temperature of 60°C for 20 minutes. Semi-dried granules were milled through a comil 193 using 1.143 mm screen. Semi-dried granules were dried further until the LCD reached less than 2.0% w / w at 105°C.

[0397] Table 14: Wet granulation parameters of feasibility batch with HPC-SL as a binder and ine grade Compound 1 (2% vs 3% Crospovidone)

[0398] Lubrication: Magnesium stearate was sifted through a 60 mesh sieve and loaded along with sized granules into the 0.2 L Turbula bin and blended for 03 minutes at 46 rpm.

[0399] Compression: The lubricated granules were compressed into tablets with different hardness level to a target weight of 450 mg using 14x6.5 mm, oval shaped punches.

[0400] Observation and Conclusion: For feasibility batch with 2% Crospovidone, a higher disintegration time was observed for high hardness tablets and hardness changes had a great impact on tablet disintegration time. Drug release profile of optimum hardness tablets was slower and complete drug release was observed only at 45 minutes. For feasibility batch with 3% Crospovidone, the disintegration time was satisfactory for tablets compressed at different hardness levels. The drug release profile of optimum hardness tablets was similar to that of high hardness tablets. Based on the disintegration time and drug release results, it can be concluded that tablet hardness had a minimal impact on drug release for feasibility batches with 3% Crospovidone. Hence 5% HPC-SL and 3% Crospovidone was selected for further studies. Table 15: Manufacturing Compound 1 Tablet 100 mg & 300 mg, scale up batch (HPC- SL)

[0401] Dry mixing: Compound 1 , Microcrystalline Cellulose PH102, Crospovidone (Polyplasdone XL) and Hydroxypropyl Cellulose SL were co-sifted through a 30 mesh screen. Sifted materials were loaded into a 6 L RMG bowl and dry mixing was performed for 10 minutes. Purified water was added into the mixture by using a peristaltic pump at a fixed speed, and granulation was performed.

[0402] Drying: Wet granules were loaded into a Fluid Bed Dryer (GPCG 2) with an inlet temperature of 60°C. Drying was continued until the LOD reached less than 2.0% w / w at 105°C.

[0403] Lubrication: Magnesium stearate were sifted through a 60 mesh sieve and loaded along with sized granules into the 5 L bin blender and blended for 03 minutes at 15 rpm.

[0404] Compression:

[0405] 100 mg Tablets: The lubricated granules were compressed into tablets with different hardness level to a target tablet weight of 150 mg using 7 mm, round shaped punches. Description of compressed tablets: Yellow colored, round shaped uncoated tablets, plain on both sides.

[0406] 300 mg Tablets: The lubricated granules were compressed into tablets with different hardness level to a target tablet weight of 450 mg using 14x6.5 mm, oval shaped punches. Description of compressed tablets: Yellow colored, oval shaped uncoated tablets, GP letter on one side, plain on the other side. Table 16: Dissolution profile of Compound 1 Tablets 100 mg and 300 mg

[0407] Physical observation during dissolution testing: 100 mg and 300 mg tablets dissolution test using 60 rpm: Mild sticking at initial time point for all units and cone formation were observed for later time points. 100 mg and 300 mg tablets using 75 rpm: Very mild sticking at initial time point for all units but no cone formation were observed.

[0408] Table 17: Dissolution profile of Compound 1 Tablets 100 mg and 300 mg, 062G comil screen batch

[0409] Observation: During granulation, 27% w / w water was utilized to attain a desired granulation end point. Kneading was performed for 60 seconds and granular mass was found optimum. Wet masses were dried in a Retsch dryer (Fluidized dryer). After complete drying (LOD Below 2%), granules were divided into two equal portions and the two portions were comilled through a 062R screen and a 062G screen, respectively. Compressibility index and Particle size distribution of sized granules were found to be similar for batches milled with the 062R screen or the 062G screen. Hence, dry milling can be performed with either the 062G screen or 062R screen. Compression parameters of 100 mg strength and 300 mg strength were found satisfactory. Hardness and DT matched with Lead prototype, scale up batches. No sticking tendency was observed during compression of the Compound 1 100 and 300 mg Tablets.

[0410] Conclusion and Summary

[0411] From the study results the following critical parameters were identified and summarized below:

[0412] Compound 1 particle size: A smaller Compound 1 particle size resulted in satisfactory granulation and compression properties in comparison with a large Compound 1 particle size. Granulation and compression were reproducible using a smaller Compound 1 particle size.

[0413] Disintegrant: Feasibility batches with Croscarmellose sodium and Sodium starch glycolate resulted in a significant increase in disintegration time upon storage at ambient conditions. Tablets composed of crospovidone did not show any change in disintegration time upon storage at ambient conditions and at accelerated conditions for up to six months. Therefore, crospovidone was selected as the binder of choice for the production of Compound 1 IR Tablets. The optimum level of crospovidone appears to be at least 3%. A 3% disintegrant level was identified to use in the production of Compound 1 IR Tablets.

[0414] Binder: Several binders were studied. Feasibility studies included prototypes composed of HPC EXF, povidone, HPMC E5 and HPC-SL. Tablets composed of povidone had good dissolution properties but high friability values. Tablets composed of HPMC E5 had good tablet hardness and friability but variable dissolution values at different hardness values. Tablets composed of HPC-SL had optimum hardness and friability values and dissolution values were fairly consistent. A study of the impact of compression force and Compound 1 particle size on tablet dissolution profiles showed that formulations composed of HPC-SL and 3% crospovidone have a sufficiently broad processing window to enable production at large scale.

[0415] Wetting agent: A few feasibility batches were conducted to assess if a wetting agent was required to facilitate granulation and dissolution. Results from these feasibility batches produced with SLS or without SLS and poloxamer showed that wetting agents are not required. Granulation Fluid level: A granulation fluid level of approx. 25% w / w and using a small particle size Compound 1 resulted in a satisfactory granulation and compression properties. In an embodiment, the granulation fluid level is 20-30% w / w .
