Description

This application is a continuation of U.S. application Ser. No. 12/200,146, filed Aug. 28, 2008, currently allowed, which is a continuation of U.S. application Ser. No. 11/977,759, filed Oct. 26, 2007, which claims the benefit of U.S. Provisional Application No. 60/854,757, filed Oct. 27, 2006, the entire contents of each are incorporated herein by reference.

1. FIELD OF THE INVENTION

Provided herein are solid forms comprising 4-[9-(tetrahydro-furan-3-yl)-8-(2,4,6-trifluoro-phenylamino)-9H-purin-2-ylamino]-cyclohexan-1-ol, compositions comprising the solid forms, methods of making the solid forms and methods of their use for the treatment of various diseases and/or disorders.

2. BACKGROUND OF THE INVENTION

The identification and selection of a solid form of a pharmaceutical compound is complex, given that a change in solid form may affect a variety of physical and chemical properties, which may provide benefits or drawbacks in processing, formulation, stability and bioavailability, among other important pharmaceutical characteristics. Potential pharmaceutical solids include crystalline solids and amorphous solids. Amorphous solids are characterized by a lack of long-range structural order, whereas crystalline solids are characterized by structural periodicity. The desired class of pharmaceutical solid depends upon the specific application; amorphous solids are sometimes selected on the basis of, e.g., an enhanced dissolution profile, while crystalline solids may be desirable for properties such as, e.g., physical or chemical stability (see, e.g., S. R. Vippagunta et al., Adv. Drug. Deliv. Rev., (2001) 48:3-26; L. Yu, Adv. Drug. Deliv. Rev., (2001) 48:27-42).
Whether crystalline or amorphous, potential solid forms of a pharmaceutical compound include single-component and multiple-component solids. Single-component solids consist essentially of the pharmaceutical compound in the absence of other compounds. Variety among single-component crystalline materials may potentially arise from the phenomenon of polymorphism, wherein multiple three-dimensional arrangements exist for a particular pharmaceutical compound (see, e.g., S. R. Byrn et al., Solid State Chemistry of Drugs, (1999) SSCI, West Lafayette). The importance of discovering polymorphs was underscored by the case of Ritonavir, an HIV protease inhibitor that was formulated as soft gelatin capsules. About two years after the product was launched, the unanticipated precipitation of a new, less soluble polymorph in the formulation necessitated the withdrawal of the product from the market until a more consistent formulation could be developed (see S. R. Chemburkar et al., Org. Process Res. Dev., (2000) 4:413-417).
Additional diversity among the potential solid forms of a pharmaceutical compound may arise from the possibility of multiple-component solids. Crystalline solids comprising two or more ionic species are termed salts (see, e.g., Handbook of Pharmaceutical Salts: Properties, Selection and Use, P. H. Stahl and C. G. Wermuth, Eds., (2002), Wiley, Weinheim). Additional types of multiple-component solids that may potentially offer other property improvements for a pharmaceutical compound or salt thereof include, e.g., hydrates, solvates, co-crystals and clathrates, among others (see, e.g., S. R. Byrn et al., Solid State Chemistry of Drugs, (1999) SSCI, West Lafayette). Moreover, multiple-component crystal forms may potentially be susceptible to polymorphism, wherein a given multiple-component composition may exist in more than one three-dimensional crystalline arrangement. The discovery of solid forms is of great importance in the development of a safe, effective, stable and marketable pharmaceutical compound.
The compound chemically named 4-[9-(tetrahydro-furan-3-yl)-8-(2,4,6-trifluoro-phenylamino)-9H-purin-2-ylamino]-cyclohexan-1-ol was disclosed in U.S. patent application Ser. No. 11/332,617, filed Jan. 12, 2006, and International Pub. No. WO 2006/076595, the entireties of each of which is incorporated by reference herein. We have discovered multiple solid forms of 4-[9-(tetrahydro-furan-3-yl)-8-(2,4,6-trifluoro-phenylamino)-9H-purin-2-ylamino]-cyclohexan-1-ol (“Compound I”), and have found that not all of the solid forms of Compound I are equally useful, as assessed by their physical and chemical properties. Thus, certain embodiments herein address the need for improved solid forms of Compound I for, e.g., purity, stability, manufacture, efficacy and bioavailability.

5. DETAILED DESCRIPTION OF THE INVENTION

5.1 Definitions

As used herein, the term “Compound I” means the compound that is chemically named 4-[9-(tetrahydro-furan-3-yl)-8-(2,4,6-trifluoro-phenylamino)-9H-purin-2-ylamino]-cyclohexan-1-ol, and includes its free base form and its ionized forms, which have undergone salt formation such that the molecule is protonated at one or more basic centers. The term “Compound I” also includes the solid forms of 4-[9-(tetrahydro-furan-3-yl)-8-(2,4,6-trifluoro-phenylamino)-9H-purin-2-ylamino]-cyclohexan-1-ol described herein.
Particular salts described below include “hydrochloride salts” or “HCl salts” of Compound I. A hydrochloride salt or HCl salt of Compound I is an acid addition salt which may be formed by reacting Compound I with hydrochloric acid.
A “bis-hydrochloride salt” or “bis-HCl salt” of Compound I is a salt which contains about two molar equivalents of hydrochloric acid per mole of Compound I.
Particular salts described below include “hydrobromide salts” or “HBr salts” of Compound I. A hydrobromide salt or HBr salt of Compound I is an acid addition salt which may be formed by reacting Compound I with hydrobromic acid.
Particular salts described below include “sulfate salts” of Compound I. A sulfate salt of Compound I is an acid addition salt which may be formed by reacting Compound I with sulfuric acid.
As used herein, the term “pharmaceutically acceptable salts” refers to salts prepared from pharmaceutically acceptable acids, including inorganic acids and organic acids. Suitable acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, carbonic, citric, dihydrogenphosphoric, ethanesulfonic, fumaric, galactunoric, gluconic, glucuronic, glutamic, hydrobromic, hydrochloric, hydriodic, isobutyric, isethionic, lactic, maleic, malic, malonic, mandelic, methanesulfonic, monohydrogencarbonic, monohydrogenphosphoric, monohydrogensulfuric, mucic, nitric, pamoic, pantothenic, phosphoric, phthalic, propionic, suberic, succinic, sulfuric, tartaric, toluenesulfonic, including p-toluenesulfonic m-toluenesulfonic and o-toluenesulfonic acids, and the like (see, e.g., S. M. Berge et al., J. Pharm. Sci., 66:1-19 (1977); and Handbook of Pharmaceutical Salts: Properties, Selection and Use, P. H. Stahl and C. G. Wermuth, Eds., (2002), Wiley, Weinheim). Also included are salts of other compounds that possess acidic character, including amino acids, such as aspartic acid and the like, and other compounds, such as aspirin, ibuprofen, saccharin, and the like. Acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable solvent. As solids, salts can exist in crystalline or amorphous modifications.
The terms “solid form,” “solid forms” and related terms, when used herein to refer to Compound I, refer to a physical form comprising Compound I which is not predominantly in a liquid or a gaseous state. Crystal forms and amorphous forms are examples of solid forms.
The term “crystalline” and related terms used herein, when used to describe a substance, component, product, or form, means that the substance, component or product is substantially crystalline as determined by X-ray diffraction. See, e.g., Remington's Pharmaceutical Sciences, 18^thed., Mack Publishing, Easton Pa., 173 (1990); The United States Pharmacopeia, 23^rded., 1843-1844 (1995).
The term “crystal form,” “crystalline form” and related terms herein refer to a crystalline solid form comprising a chemical compound, and may refer to a particular single-component or multiple-component crystal form, including, but not limited to, a polymorph, a solvate, a hydrate, a cocrystal or other molecular complex, a salt, a solvate of a salt, a hydrate of a salt, a cocrystal or other molecular complex of a salt, or a polymorph thereof.
The terms “polymorphs,” “polymorphic forms” and related terms herein refer to two or more crystal forms that comprise the same molecule, molecules or ions. Different polymorphs may have different physical properties such as, for example, melting temperatures, heats of fusion, solubilities, dissolution rates and/or vibrational spectra as a result of the arrangement or conformation of the molecules or ions in the crystal lattice. The differences in physical properties exhibited by polymorphs affect pharmaceutical parameters such as storage stability, compressibility and density (important in formulation and product manufacturing), and dissolution rate (an important factor in bioavailability). Differences in stability can result from changes in chemical reactivity (e.g., differential oxidation, such that a dosage form discolors more rapidly when comprised of one polymorph than when comprised of another polymorph) or mechanical changes (e.g., tablets crumble on storage as a kinetically favored polymorph converts to thermodynamically more stable polymorph) or both (e.g., tablets of one polymorph are more susceptible to breakdown at high humidity). As a result of solubility/dissolution differences, in the extreme case, some polymorphic transitions may result in lack of potency or, at the other extreme, toxicity. In addition, the physical properties of the crystal may be important in processing; for example, one polymorph might be more likely to form solvates or might be difficult to filter and wash free of impurities (e.g., particle shape and size distribution might be different between polymorphs).
The term “solvate” and “solvated,” as used herein, refer to a crystal form of a substance which contains solvent. The term “hydrate” and “hydrated” refer to a solvate wherein the solvent is water. “Polymorphs of solvates” refers to the existence of more than one crystal form for a particular solvate composition. Similarly, “polymorphs of hydrates” refers to the existence of more than one crystal form for a particular hydrate composition. The term “desolvated solvate,” as used herein, refers to a crystal form of a substance which can only be made by removing the solvent from a solvate.
The term “amorphous,” “amorphous form,” and related terms used herein mean that the substance, component or product in question is not substantially crystalline as determined by X-ray diffraction. In certain embodiments, a sample comprising an amorphous form of a substance may be substantially free of other amorphous forms and/or crystal forms.
As used herein, and unless otherwise specified, the terms “about” and “approximately,” when used in connection with doses, amounts, or weight percent of ingredients of a composition or a dosage form, mean a dose, amount, or weight percent that is recognized by those of ordinary skill in the art to provide a pharmacological effect equivalent to that obtained from the specified dose, amount, or weight percent. Specifically, the terms “about” and “approximately,” when used in this context, contemplate a dose, amount, or weight percent within 15%, more specifically within 10%, more specifically within 5%, of the specified dose, amount, or weight percent.
Techniques for characterizing crystal forms and amorphous forms include, but are not limited to, thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray powder diffractometry (XRPD), single-crystal X-ray diffractometry, vibrational spectroscopy, e.g., infrared (IR) and Raman spectroscopy, solid-state and solution nuclear magnetic resonance (NMR) spectroscopy, optical microscopy, hot stage optical microscopy, scanning electron microscopy (SEM), electron crystallography and quantitative analysis, particle size analysis (PSA), surface area analysis, solubility studies and dissolution studies.
As used herein, and unless otherwise specified, the terms “about” and “approximately,” when used in connection with a numeric value or range of values which is provided to characterize a particular solid form, e.g., a specific temperature or temperature range, such as, for example, that describing a melting, dehydration, desolvation or glass transition temperature; a mass change, such as, for example, a mass change as a function of temperature or humidity; a solvent or water content, in terms of, for example, mass or a percentage; or a peak position, such as, for example, in analysis by IR or Raman spectroscopy or XRPD; indicate that the value or range of values may deviate to an extent deemed reasonable to one of ordinary skill in the art while still describing the particular solid form. Specifically, the terms “about” and “approximately,” when used in this context, indicate that the numeric value or range of values may vary, in particular embodiments, within 20%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1.5%, 1%, 0.5%, or 0.25% of the recited value or range of values.
As used herein, a solid form (e.g., a crystal form or amorphous form) that is “substantially pure” may comprise, in particular embodiments, less than about 20%, 15%, 10%, 5%, 3%, 2%, 1%, 0.75%, 0.5%, 0.25% or 0.1% by weight of one or more other crystal forms, amorphous forms and/or chemical compounds. In certain embodiments, a solid form that is substantially pure is substantially free of one or more other particular crystal forms, amorphous forms and/or chemical compounds.
As used herein and unless otherwise indicated, a composition that is “substantially free” of a solid form and/or chemical substance contains less than about 20%, 15%, 10%, 5%, 3%, 2%, 1%, 0.75%, 0.5%, 0.25% or 0.1% by weight of the solid form and/or chemical compound.
As used herein, and unless otherwise specified, the terms “treat,” “treating” and “treatment” refer to the eradication or amelioration of a disease or disorder, or of one or more symptoms associated with the disease or disorder. In certain embodiments, the terms refer to minimizing the spread or worsening of the disease or disorder resulting from the administration of one or more prophylactic or therapeutic agents to a subject with such a disease or disorder.
As used herein, and unless otherwise specified, the terms “prevent,” “preventing” and “prevention” refer to the prevention of the onset, recurrence or spread of a disease or disorder, or of one or more symptoms thereof.
As used herein, and unless otherwise specified, the terms “manage,” “managing” and “management” refer to preventing or slowing the progression, spread or worsening of a disease or disorder, or of one or more symptoms thereof. Often, the beneficial effects that a subject derives from a prophylactic or therapeutic agent do not result in a cure of the disease or disorder.
As used herein, and unless otherwise specified, a “therapeutically effective amount” of a compound is an amount sufficient to provide a therapeutic benefit in the treatment or management of a disease or disorder, or to delay or minimize one or more symptoms associated with the disease or disorder. A therapeutically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment or management of the disease or disorder. The term “therapeutically effective amount” can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of disease or disorder, or enhances the therapeutic efficacy of another therapeutic agent.
As used herein, and unless otherwise specified, a “prophylactically effective amount” of a compound is an amount sufficient to prevent a disease or disorder, or prevent its recurrence. A prophylactically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other agents, which provides a prophylactic benefit in the prevention of the disease. The term “prophylactically effective amount” can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.
The term “composition” as used herein is intended to encompass a product comprising the specified ingredients (and in the specified amounts, if indicated), as well as any product which results, directly or indirectly, from combination of the specified ingredients in the specified amounts. By “pharmaceutically acceptable” it is meant the diluent, excipient or carrier must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.
The term “therapeutically and prophylactically effective amount” refers to the amount of the subject solid form that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician or that is sufficient to prevent development of or alleviate to some extent one or more of the symptoms of the disease being treated.
The terms “subject” and “patient,” unless otherwise specified, are defined herein to include animals such as mammals, including, but not limited to, primates (e.g., humans), cows, sheep, goats, horses, dogs, cats, rabbits, rats, mice and the like. In specific embodiments, the subject or patient is a human.
In addition to solid forms comprising Compound I, embodiments herein provide solid forms of prodrugs of Compound I. Prodrugs of the compounds described herein are structurally modified forms of the compound that readily undergo chemical changes under physiological conditions to provide the compound. Additionally, prodrugs can be converted to the compound by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to a compound when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent. Prodrugs are often useful because, in some situations, they may be easier to administer than the compound, or parent drug. They may, for instance, be bioavailable by oral administration whereas the parent drug is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. A wide variety of prodrug derivatives are known in the art, such as those that rely on hydrolytic cleavage or oxidative activation of the prodrug. An example, without limitation, of a prodrug would be a compound which is administered as an ester (the “prodrug”), but then is metabolically hydrolyzed to the carboxylic acid, the active entity. Additional examples include peptidyl derivatives of a compound.
In certain embodiments, Compound I may contain unnatural proportions of atomic isotopes at one or more of the atoms. For example, the compound may be radiolabeled with radioactive isotopes, such as for example tritium (³H), iodine-125 (¹²⁵I) sulfur-35 (³⁵S), or carbon-14 (¹⁴C). Radiolabeled compounds are useful as therapeutic agents, e.g., cancer therapeutic agents, research reagents, e.g., binding assay reagents, and diagnostic agents, e.g., in vivo imaging agents. All isotopic variations of the Compound I, whether radioactive or not, are intended to be encompassed within the scope of the embodiments provided herein.

5.4 Pharmaceutical Compositions and Routes of Administration

The solid forms comprising Compound I can be administered to a patient orally or parenterally in the conventional form of preparations, such as capsules, microcapsules, tablets, granules, powder, troches, pills, suppositories, injections, suspensions and syrups. Suitable formulations can be prepared by methods commonly employed using conventional, organic or inorganic additives, such as an excipient (e.g., sucrose, starch, mannitol, sorbitol, lactose, glucose, cellulose, talc, calcium phosphate or calcium carbonate), a binder (e.g., cellulose, methylcellulose, hydroxymethylcellulose, polypropylpyrrolidone, polyvinylpyrrolidone, gelatin, gum arabic, polyethyleneglycol, sucrose or starch), a disintegrator (e.g., starch, carboxymethylcellulose, hydroxypropylstarch, low substituted hydroxypropylcellulose, sodium bicarbonate, calcium phosphate or calcium citrate), a lubricant (e.g., magnesium stearate, light anhydrous silicic acid, talc or sodium lauryl sulfate), a flavoring agent (e.g., citric acid, menthol, glycine or orange powder), a preservative (e.g, sodium benzoate, sodium bisulfite, methylparaben or propylparaben), a stabilizer (e.g., citric acid, sodium citrate or acetic acid), a suspending agent (e.g., methylcellulose, polyvinyl pyrroliclone or aluminum stearate), a dispersing agent (e.g., hydroxypropylmethylcellulose), a diluent (e.g., water), and base wax (e.g., cocoa butter, white petrolatum or polyethylene glycol). The effective amount of the solid forms comprising Compound I in the pharmaceutical composition may be at a level that will exercise the desired effect; for example, about 0.005 mg/kg of a patient's body weight to about 10 mg/kg of a patient's body weight in unit dosage for both oral and parenteral administration.
The physical characteristics of different solid forms can, in some cases, affect their bioavailability, but the amounts of the solid forms that are therapeutically or prophylactically effective in the treatment of various diseases and conditions can be readily determined by those of ordinary skill in the pharmacy or medical arts. In general, the solid forms comprising Compound I can be administered one to four times a day in a dose of about 0.005 mg/kg of a patient's body weight to about 10 mg/kg of a patient's body weight in a patient, but the above dosage may be properly varied depending on the age, body weight and medical condition of the patient and the type of administration. In one embodiment, the dose is about 0.01 mg/kg of a patient's body weight to about 5 mg/kg of a patient's body weight, about 0.05 mg/kg of a patient's body weight to about 1 mg/kg of a patient's body weight, about 0.1 mg/kg of a patient's body weight to about 0.75 mg/kg of a patient's body weight or about 0.25 mg/kg of a patient's body weight to about 0.5 mg/kg of a patient's body weight. In one embodiment, one dose is given per day. In any given case, the amount of the solid form comprising Compound I administered will depend on such factors as the solubility of the active component, the formulation used and the route of administration.
In another embodiment, provided herein are methods for the treatment or prevention of a disease or disorder comprising the administration of about 0.375 mg/day to about 750 mg/day, about 0.75 mg/day to about 375 mg/day, about 3.75 mg/day to about 75 mg/day, about 7.5 mg/day to about 55 mg/day or about 18 mg/day to about 37 mg/day of a solid form comprising Compound I to a patient in need thereof.

In a particular embodiment, the methods disclosed herein comprise the administration of 400 mg/day, 600 mg/day or 800 mg/day of a solid form comprising Compound Ito a patient in need thereof.
In another embodiment, provided herein are unit dosage formulations that comprise between about 1 mg and 200 mg, about 35 mg and about 1400 mg, about 125 mg and about 1000 mg, about 250 mg and about 1000 mg, or about 500 mg and about 1000 mg of a solid form comprising Compound I.
In a particular embodiment, provided herein are unit dosage formulation comprising about 100 mg or 400 mg of a solid form comprising Compound I.
In another embodiment, provided herein are unit dosage formulations that comprise 1 mg, 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 35 mg, 50 mg, 70 mg, 100 mg, 125 mg, 140 mg, 175 mg, 200 mg, 250 mg, 280 mg, 350 mg, 500 mg, 560 mg, 700 mg, 750 mg, 1000 mg or 1400 mg of a solid form comprising Compound I.
A solid form comprising Compound I can be administered once, twice, three, four or more times daily. In a particular embodiment, doses of 600 mg or less are administered as a once daily dose and doses of more than 600 mg are administered twice daily in an amount equal to one half of the total daily dose.
A solid form comprising Compound I can be administered orally for reasons of convenience. In one embodiment, when administered orally, Compound I is administered with a meal and water. In another embodiment, the Compound I is dispersed in water or juice (e.g., apple juice or orange juice) and administered orally as a suspension.
The solid form comprising Compound I can also be administered intradermally, intramuscularly, intraperitoneally, percutaneously, intravenously, subcutaneously, intranasally, epidurally, sublingually, intracerebrally, intravaginally, transdermally, rectally, by inhalation, or topically to the ears, nose, eyes, or skin. The mode of administration is left to the discretion of the health-care practitioner, and can depend in-part upon the site of the medical condition.
In one embodiment, provided herein are capsules containing a solid form comprising Compound I without an additional carrier, excipient or vehicle.
In another embodiment, provided herein are compositions comprising an effective amount of a solid form comprising Compound I and a pharmaceutically acceptable carrier or vehicle, wherein a pharmaceutically acceptable carrier or vehicle can comprise an excipient, diluent, or a mixture thereof. In one embodiment, the composition is a pharmaceutical composition.
The compositions can be in the form of tablets, chewable tablets, capsules, solutions, parenteral solutions, troches, suppositories and suspensions and the like. Compositions can be formulated to contain a daily dose, or a convenient fraction of a daily dose, in a dosage unit, which may be a single tablet or capsule or convenient volume of a liquid. In one embodiment, the solutions are prepared from water-soluble salts, such as the hydrochloride salt. In general, all of the compositions are prepared according to known methods in pharmaceutical chemistry. Capsules can be prepared by mixing a solid form comprising Compound I with a suitable carrier or diluent and filling the proper amount of the mixture in capsules. The usual carriers and diluents include, but are not limited to, inert powdered substances such as starch of many different kinds, powdered cellulose, especially crystalline and microcrystalline cellulose, sugars such as fructose, mannitol and sucrose, grain flours and similar edible powders.
Tablets can be prepared by direct compression, by wet granulation, or by dry granulation. Their formulations usually incorporate diluents, binders, lubricants and disintegrators as well as the compound. Typical diluents include, for example, various types of starch, lactose, mannitol, kaolin, calcium phosphate or sulfate, inorganic salts such as sodium chloride and powdered sugar. Powdered cellulose derivatives are also useful. Typical tablet binders are substances such as starch, gelatin and sugars such as lactose, fructose, glucose and the like. Natural and synthetic gums are also convenient, including acacia, alginates, methylcellulose, polyvinylpyrrolidine and the like. Polyethylene glycol, ethylcellulose and waxes can also serve as binders.
A lubricant might be necessary in a tablet formulation to prevent the tablet and punches from sticking in the die. The lubricant can be chosen from such slippery solids as talc, magnesium and calcium stearate, stearic acid and hydrogenated vegetable oils. Tablet disintegrators are substances that swell when wetted to break up the tablet and release the compound. They include starches, clays, celluloses, algins and gums. More particularly, corn and potato starches, methylcellulose, agar, bentonite, wood cellulose, powdered natural sponge, cation-exchange resins, alginic acid, guar gum, citrus pulp and carboxymethyl cellulose, for example, can be used as well as sodium lauryl sulfate. Tablets can be coated with sugar as a flavor and sealant, or with film-forming protecting agents to modify the dissolution properties of the tablet. The compositions can also be formulated as chewable tablets, for example, by using substances such as mannitol in the formulation.
When it is desired to administer a solid form comprising Compound I as a suppository, typical bases can be used. Cocoa butter is a traditional suppository base, which can be modified by addition of waxes to raise its melting point slightly. Water-miscible suppository bases comprising, particularly, polyethylene glycols of various molecular weights are in wide use.
The effect of the solid form comprising Compound I can be delayed or prolonged by proper formulation. For example, a slowly soluble pellet of the solid form comprising Compound I can be prepared and incorporated in a tablet or capsule, or as a slow-release implantable device. The technique also includes making pellets of several different dissolution rates and filling capsules with a mixture of the pellets. Tablets or capsules can be coated with a film that resists dissolution for a predictable period of time. Even the parenteral preparations can be made long-acting, by dissolving or suspending the solid form comprising Compound I in oily or emulsified vehicles that allow it to disperse slowly in the serum.

Compound A (2,4-dichloro-5-nitropyrimidine) (363 g, 1.87 mol, 1.0 eq.) was charged to a reaction vessel with (S)-3-amino tetrahydrofuran (1) (230 g, 1.87 mol, 1.0 eq.) and CH₂Cl₂(DCM) (3.45 L, 15 vol.). The displacement of the 4-chloro group with (S)-3-amino tetrahydrofuran (1) in the presence of DIPEA (684 mL, 3.93 mol, 2.1 eq.) was performed at −30 to −20° C. followed by warming the reaction to 20-25° C. over 10-18 h. Upon consumption of Compound A (IPC indicated <1 AP, HPLC) the reaction mixture was charged with trans-4-amino cyclohexanol (3) (215 g, 1.87 mol, 1.0 eq.) and additional DIPEA (391 mL, 2.24 mol, 1.2 eq.). The mixture was heated at 35-40° C. for 10-18 h or until HPLC analysis indicated <1 AP, (HPLC) of 2. A solvent swap of DCM to MeCN was carried out by distilling off about 12 volumes of DCM and adding about 3 volumes of MeCN. Water (4.6 L, 20 vol) was then added and the reaction mixture was cooled to between about 0-5° C. and stirred for about 1-2 h to give Compound B as a filterable solid. The solids were collected by filtration, washed with water (2.3 L, 10 vol), washed with MTBE (2.3 L, 10 vol) and dried at 35-40° C. until KF<3% (yield 82-89 M %, HPLC purity 90-95 AP).
Stage 2A involves the reduction of the nitro group of Compound B to the corresponding aniline (4). A mixture of Compound B (120 g, 0.37 mol, 1.0 eq.) and 10% Pd/C (50% wet, 10 wt %) (12 g, 10 wt %) were charged with MeOH (1.5 L, 12.5 vol). The mixture was hydrogenated at 35-40° C., 40-50 psi H₂for 2-4 h with shaking (or until HPLC analysis indicated <1 AP (HPLC) of Compound B remaining) The catalyst was removed by filtration through a celite bed. The celite was washed with warm (35-40° C.) MeOH (1.2 L, 10 vol). The filtrate was concentrated and a solvent swap of MeOH to THF was carried out by distilling off MeOH and charging with THF (1.8 L, 15 vol) to give a THF solution/slurry of Stage 2A product (4), which was carried to the next step (yield assumed >99 M %, HPLC purity >94 AP). The solvent swap with THF was performed until the ¹H NMR of the distillate revealed <2% of MeOH. The THF solution can be stored for up to 24 h at ambient temperature (20-25° C.) under N₂without degradation.
Stage 2B involves the coupling of Stage 2A product (4) with commercially available 2,4,6-trifluorophenyl isothiocyanate (5). Stage 2A product (4) (217.7 g, 0.742 mol, 1 eq.) as a THF solution was reacted with 2,4,6-trifluorophenyl isothiocyanate (5) with stirring at 20-25° C. for 15-18 h (or until IPC indicated <1 AP (HPLC) of (4)) to afford the intermediate thiourea (6). The reaction was charged with EDC (156.5 g, 0.816 mol, 1.1 eq.) and heated at 60-65° C. for 3.5-6 h (or until IPC indicated <1 AP (HPLC) of (6)) to give the desired crude purine (Compound I). The mixture was then treated with AcOH/H₂O (212 mL, 3.71 mol, 5 eq.) and water (650 mL, 3 vol) and heated for 1.5-2 h at 60-65° C. The mixture was then cooled to 20-25° C. and diluted with EtOAc (3.3 L, 15 vol). The phases were separated and the organic phase was washed with water (2×5 vol), Na₂CO₃(2×5 vol, 5 eq.) (or until pH=9-11) and again with water (5 vol). The organic phase (EtOAc) was collected and water was removed by azeotropic distillation using EtOAc) until KF<5%. A solvent swap with EtOH was performed by distilling off EtOAc and charging with EtOH (1.1 L, 5 vol) until the ¹H NMR of the distillate revealed <2% of EtOAc. The ethanol slurry of crude Compound I can be stored for up to 64 h at 20-25° C. under an inert atmosphere. The resultant slurry was then heated to 78-83° C. and water (15 volumes) was added at such a rate as to maintain the reaction temperature at >75° C. The solution was seeded (1-2 wt % Compound I), followed by the addition of water (5 volumes) and cooling of the reaction mixture to 20-25° C. Crude Compound I was collected by filtration and dried in vacuo at 35-40° C. for 18-24 h (or until KF<1%) (yield 55-62 M %, HPLC purity 88-99 AP).
Stage 3 involves recrystallization of crude Compound I. Crude Compound I (717 g, 1.0 eq.) was heated in EtOH (6.1 L, 8.5 vol) at 78-83° C. and stirred until solids dissolved. The solution of crude Compound I was cooled to 50-55° C. and polish filtered. The solution was then heated to 78-83° C. and water (10.8 L, 15 volumes) was added while maintaining the temperature at >75° C. The solution was seeded (7 g, 1-2 wt % Compound I), followed by cooling of the reaction mixture to 20-25° C. Recrystallized Compound I was collected by filtration and dried at up to 40° C. (or until KF<1%) (recovery 78-80 M %, HPLC purity 99.42 AP).
Compound I was also prepared according to the alternative methods depicted in FIG. 15 and FIG. 16.

6.2 Example 2

Preparation of Solid Forms: General Procedures

Equilibration/slurry and evaporation experiments were carried out by adding an excess of Compound I free base or HCl salt to 2 mL of solvent. The resulting mixture was agitated for at least 24 hours at 25° C. and 50° C. in two separate sets of experiments. Upon reaching equilibrium, the saturated supernatant solution was removed and allowed to evaporate slowly in an open vial under nitrogen at 25° C. or 50° C., respectively. The slurry resulting from the equilibration was filtered and air-dried.
Crystallization using cooling methods were performed for Compound I free base. Compound I was dissolved in a solvent at an elevated temperature, approximately 65° C., and allowed to cool to ambient temperature. Samples that did not crystallize at ambient temperature were placed in a refrigerator (about 2-8° C.). Solids were isolated by decantation and allowed to dry in the air.
Precipitations for Compound I free base were also carried out using solvent/antisolvent combinations. The solid was dissolved in a solvent in Compound I had high solubility, and then a selected solvent in which Compound I was relatively insoluble (i.e., an antisolvent) was added to the solution. A precipitate was formed immediately in some solvent/antisolvent systems. If precipitation did not immediately occur, the resulting mixture was allowed to cool in a refrigerator until a precipitate formed. The precipitate was then isolated by decantation and allowed to dry in the air.

Approximate Solubilities of Solid Forms

A weighed sample comprising either the free base or the HCl salt of Compound I was treated with 2 mL of a solvent (either HPLC or reagent grade). The resulting mixture was agitated for at least 24 hours at about 25° C. When all of the solids were dissolved by visual inspection, the estimated solubility was calculated. The solubility was estimated from these experiments based on the total volume of solvent used to give a complete solution. Measured values are provided in the tables below. The actual solubility may be greater than those calculated due to the use of a large amount of solvent or a slow rate of dissolution. A known volume of filtrate was evaporated to dryness and the weight of the residue was measured.

Analytical Methods

6.9.1 X-Ray Powder Diffraction
X-ray powder diffraction (XRPD) measurements were performed in accordance with United States Pharmacopeia (USP) monograph <941> entitled “X-ray Diffraction” (See, e.g., The United States Pharmacopeia, The National Formulary, 2003, The Unites States Pharmacopeial Convention, Inc., Rockville, Md., 2002, which is herein incorporated by reference in its entirety). A Thermo ARL X′TRA X-ray powder diffractometer (Thermo Electron Corp., Waltham, Mass.), equipped with Nickel-filtered Cu Kα radiation at 1.54 A, was used for XRPD measurements from about 1.5 °2θ to about 40 °2θ, with a step size of about 0.020°, a count time of about 0.50 seconds per step, and a step scan rate of about 2.40°/min. The instrument was equipped with a fine focus X-ray tube. The voltage and amperage were set at 45 kV and 40 mA, respectively. The divergence slits were set at 0.5 mm and 0.2 mm. Diffracted radiation was measured using a Peltier-cooled Si (Li) solid-state detector. Representative XRPD patterns were presented displaying intensity (counts per second) versus position (° 2θ). A sintered alumina standard was used to check peak positions. Peak positions may vary from sample to sample by approximately ±0.1 °2θ. Variation in peak position may depend upon multiple factors, including particle size, sample preparation, data collection temperature and parameters. Variation in peak intensity may occur, e.g., as a result of preferred orientation and/or variation in crystal habit.
6.9.2 Thermal Analysis
Differential scanning calorimetry (DSC) measurements were performed in accordance with United States Pharmacopeia (USP) monograph <891> entitled “Thermal Analysis” (See, e.g., The United States Pharmacopeia, The National Formulary, 2003, The Unites States Pharmacopeial Convention, Inc., Rockville, Md., 2002, which is incorporated herein by reference in its entirety). A DSC model Q1000 (TA Instruments, New Castle, Del.) was used to obtain DSC measurements. Indium was used as the calibration standard. Analysis was performed on accurately weighed samples with masses ranging between about 2 mg and about 5 mg. Samples were heated under nitrogen from about 25° C. to about 300° C. at a constant heating rate of about 10° C./min. Representative DSC thermograms were presented displaying heat flow (W/g) versus temperature (° C.). Melting points were reported as extrapolated onset temperatures.
Thermal gravimetric analysis (TGA) measurements were performed in accordance with United States Pharmacopeia (USP) monograph <891> entitled “Thermal Analysis” (See, e.g., The United States Pharmacopeia, The National Formulary, 2003, The Unites States Pharmacopeial Convention, Inc., Rockville, Md., 2002, which is incorporated herein by reference in its entirety). A TGA model Q500 (TA Instruments, New Castle, Del.) was used to obtain TGA measurements. Analysis was performed on samples with masses ranging between about 10.0 mg and about 50.0 mg. Samples were heated under nitrogen from about 25° C. to about 300° C. at a constant heating rate of about 10° C./min. Representative TGA thermograms were presented with one trace displaying weight (%) versus temperature (° C.), and a second trace displaying derivative weight (%/° C.) versus temperature (° C.).
6.9.3 Morphology Analysis
Morphology analysis of the samples was carried out using an Olympus optical microscope. The instrument was calibrated according to USP standards.
6.9.4 Moisture Sorption Analysis
Hygroscopicity (moisture sorption/desorption) was determined by Dynamic Vapor Sorption (DVS). A solid sample comprising Compound I ranging from 10 to 50 mg was placed into the DVS instrument at 0% relative humidity (RH). The RH was increased from 0% to 80% or 95%. The RH was then decreased in a similar manner to accomplish a full sorption/desorption cycle.
6.9.5 HPLC Analysis
