  • Ubls ubiquitin-like molecules
  • the post-translational modification of proteins by ubiquitin-like molecules (ubls) is an important regulatory process within cells, playing key roles in controlling many biological processes including cell division, cell signaling and the immune response.
  • Ubls are small proteins that are covalently attached to a lysine on a target protein via an isopeptide linkage with a C-terminal glycine of the ubl.
  • the ubiquitin-like molecule alters the molecular surface of the target protein and can affect such properties as
  • Ubiquitin and other ubls are activated by a specific El enzyme which catalyzes the formation of an acyl-adenylate intermediate with the C-terminal glycine of the ubl.
  • the activated ubl molecule is then transferred to the catalytic cysteine residue within the El enzyme through formation of a thioester bond intermediate.
  • the El-ubl intermediate and an E2 associate, resulting in a thioester exchange wherein the ubl is transferred to the active site cysteine of the E2.
  • the ubl is then conjugated to the target protein, either directly or in conjunction with an E3 ligase, through isopeptide bond formation with the amino group of a lysine side chain in the target protein.
  • Targeting El activating enzymes provides a unique opportunity to interfere with a variety of biochemical pathways important for maintaining the integrity of cell division and cell signaling.
  • El activating enzymes function at the first step of ubl conjugation pathways; thus, inhibition of an El activating enzyme will specifically modulate the downstream biological consequences of the ubl modification.
  • inhibition of these activating enzymes, and the resultant inhibition of downstream effects of ubl-conjugation represents a method of interfering with the integrity of cell division, cell signaling, and several aspects of cellular physiology which are important for disease mechanisms.
  • El enzymes such as UAE, NAE, and SAE, as regulators of diverse cellular functions, are potentially important therapeutic targets for the identification of novel approaches to treatment of diseases and disorders.
  • compositions should be as pure as possible and its stability on long-term storage must be guaranteed under various environmental conditions. These properties are absolutely essential to prevent the appearance of unintended degradation products in pharmaceutical compositions, which degradation products may be potentially toxic or result simply in reducing the potency of the composition.
  • a primary concern for the manufacture of large-scale pharmaceutical compounds is that the active substance should have a stable crystalline morphology to ensure consistent processing parameters and pharmaceutical quality. If an unstable crystalline form is used, crystal morphology may change during manufacture and/or storage resulting in quality control problems, and formulation irregularities. Such a change may affect the reproducibility of the manufacturing process and thus lead to final formulations which do not meet the high quality and stringent requirements imposed on formulations of pharmaceutical compositions. In this regard, it should be generally borne in mind that any change to the solid state of a pharmaceutical composition which can improve its physical and chemical stability gives a significant advantage over less stable forms of the same drug.
  • polymorphism When a compound crystallizes from a solution or slurry, it may crystallize with different spatial lattice arrangements, a property referred to as "polymorphism.” Each of the crystal forms is a "polymorph.” While polymorphs of a given substance have the same chemical composition, they may differ from each other with respect to one or more physical properties, such as solubility and dissociation, true density, melting point, crystal shape, compaction behavior, flow properties, and/or solid state stability.
  • the polymorphic behavior of drugs can be of great importance in pharmacy and pharmacology.
  • the differences in physical properties exhibited by polymorphs affect practical parameters such as storage stability, compressibility and density (important in formulation and product manufacturing), and dissolution rates (an important factor in determining bio-availability).
  • Differences in stability can result from changes in chemical reactivity (e.g., differential oxidation, such that a dosage form discolors more rapidly when it is one polymorph than when it is 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).
  • the physical properties of the crystal may be important in processing: for example, one polymorph might be more likely to form solvates that cause the solid form to aggregate and increase the difficulty of solid handling, or might be difficult to filter and wash free of impurities (i.e., particle shape and size distribution might be different between one polymorph relative to other).
  • hydrochloride salt exhibits limited chemical stability during accelerated stress condition.

The invention is also directed to the pharmaceutical use of a cocrystal form as an El activating enzyme inhibitor, as well as a pharmaceutical composition comprising a cocrystal form. The invention is further directed to a method of treatment comprising administering a cocrystal form of ((l S,2S,4R)-4-{4-[(l S)-2,3-dihydro-lH-inden-l-ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7- yl}-2-hydroxycyclopentyl)methyl sulfamate of formula (Γ). Background Art
[0004] The post-translational modification of proteins by ubiquitin-like molecules (ubls) is an important regulatory process within cells, playing key roles in controlling many biological processes including cell division, cell signaling and the immune response. Ubls are small proteins that are covalently attached to a lysine on a target protein via an isopeptide linkage with a C-terminal glycine of the ubl. The ubiquitin-like molecule alters the molecular surface of the target protein and can affect such properties as
protein-protein interactions, enzymatic activity, stability and cellular localization of the target.
[0005] Ubiquitin and other ubls are activated by a specific El enzyme which catalyzes the formation of an acyl-adenylate intermediate with the C-terminal glycine of the ubl. The activated ubl molecule is then transferred to the catalytic cysteine residue within the El enzyme through formation of a thioester bond intermediate. The El-ubl intermediate and an E2 associate, resulting in a thioester exchange wherein the ubl is transferred to the active site cysteine of the E2. The ubl is then conjugated to the target protein, either directly or in conjunction with an E3 ligase, through isopeptide bond formation with the amino group of a lysine side chain in the target protein.
[0006] Targeting El activating enzymes provides a unique opportunity to interfere with a variety of biochemical pathways important for maintaining the integrity of cell division and cell signaling. El activating enzymes function at the first step of ubl conjugation pathways; thus, inhibition of an El activating enzyme will specifically modulate the downstream biological consequences of the ubl modification. As such, inhibition of these activating enzymes, and the resultant inhibition of downstream effects of ubl-conjugation, represents a method of interfering with the integrity of cell division, cell signaling, and several aspects of cellular physiology which are important for disease mechanisms.
Thus, El enzymes such as UAE, NAE, and SAE, as regulators of diverse cellular functions, are potentially important therapeutic targets for the identification of novel approaches to treatment of diseases and disorders.

[0010] The large-scale manufacturing of a pharmaceutical composition poses many
challenges to the chemist and chemical engineer. While many of these challenges relate to the handling of large quantities of reagents and control of large-scale reactions, the handling of the final product poses special challenges linked to the nature of the final active product itself. Not only must the product be prepared in high yield, be stable, and capable of ready isolation, the product must possess properties that are suitable for the types of pharmaceutical preparations in which they are likely to be ultimately used. The stability of the active ingredient of the pharmaceutical preparation must be considered during each step of the manufacturing process, including the synthesis, isolation, bulk storage, pharmaceutical formulation and long-term formulation. Each of these steps may be impacted by various environmental conditions of temperature and humidity.
[0011] The pharmaceutically active substance used to prepare the pharmaceutical
compositions should be as pure as possible and its stability on long-term storage must be guaranteed under various environmental conditions. These properties are absolutely essential to prevent the appearance of unintended degradation products in pharmaceutical compositions, which degradation products may be potentially toxic or result simply in reducing the potency of the composition.
[0012] A primary concern for the manufacture of large-scale pharmaceutical compounds is that the active substance should have a stable crystalline morphology to ensure consistent processing parameters and pharmaceutical quality. If an unstable crystalline form is used, crystal morphology may change during manufacture and/or storage resulting in quality control problems, and formulation irregularities. Such a change may affect the reproducibility of the manufacturing process and thus lead to final formulations which do not meet the high quality and stringent requirements imposed on formulations of pharmaceutical compositions. In this regard, it should be generally borne in mind that any change to the solid state of a pharmaceutical composition which can improve its physical and chemical stability gives a significant advantage over less stable forms of the same drug.
[0013] When a compound crystallizes from a solution or slurry, it may crystallize with different spatial lattice arrangements, a property referred to as "polymorphism." Each of the crystal forms is a "polymorph." While polymorphs of a given substance have the same chemical composition, they may differ from each other with respect to one or more physical properties, such as solubility and dissociation, true density, melting point, crystal shape, compaction behavior, flow properties, and/or solid state stability.
[0014] As described generally above, the polymorphic behavior of drugs can be of great importance in pharmacy and pharmacology. The differences in physical properties exhibited by polymorphs affect practical parameters such as storage stability, compressibility and density (important in formulation and product manufacturing), and dissolution rates (an important factor in determining bio-availability). Differences in stability can result from changes in chemical reactivity (e.g., differential oxidation, such that a dosage form discolors more rapidly when it is one polymorph than when it is 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). In addition, the physical properties of the crystal may be important in processing: for example, one polymorph might be more likely to form solvates that cause the solid form to aggregate and increase the difficulty of solid handling, or might be difficult to filter and wash free of impurities (i.e., particle shape and size distribution might be different between one polymorph relative to other).
[0015] While drug formulations having improved chemical and physical properties are desired, there is no predictable means for preparing new drug forms (e.g., polymorphs) of existing molecules for such formulations. These new forms would provide consistency in physical properties over a range of environments common to manufacturing and composition usage. Thus, there is a need for new drug forms that are useful for inhibiting El activity in vitro and in vivo, and are useful for the treatment of disorders of cell proliferation, particularly cancer, and other disorders associated with El activity, as well as having properties suitable for large-scale manufacturing and formulation.
[0016] The hydrochloride salt of ((l S,2S,4R)-4-{4-[(l S)-2,3-dihydro-lH-inden-l- ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-2-hydroxycyclopentyl)methyl sulfamate (i), crystalline forms thereof, solvates thereof, and methods of making them are described in U.S. Appl. Pub. No. 2011/0021544.
[0017] However, U.S. Appl. Pub. No. 2011/0021544 also disclosed that the above
hydrochloride salt exhibits limited chemical stability during accelerated stress condition. Therefore, there is a need for new drug forms of ((l S,2S,4R)-4-{4-[(l S)-2,3-dihydro-lH- inden-l-ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-2-hydroxycyclopentyl)methyl sulfamate (i), including other salts, crystalline forms thereof, cocrystals, and solvates thereof.

DETAILED DESCRIPTION OF THE INVENTION
Definitions and Abbreviations
[0050] As used above, and throughout the description of the invention, the following terms, unless otherwise indicated, shall be understood to have the following meanings.
[0051] As used herein, "cocrystal" refers to a crystalline structure composed of at least two components in the same crystal lattice, where the components may be atoms, ions or molecules. Cocrystals consist of two or more components that form a unique crystalline structure having unique properties. Cocrystals can encompass hydrates, solvates and clathrates.
[0052] As used herein, "crystalline" and "crystalline form" refer to a solid having a highly regular chemical structure, including cocrystals. For the purposes of this application, the terms "crystalline form" and "polymorph" are synonymous; the terms distinguish between cocrystal forms that have different properties (e.g., different XRPD patterns, different DSC scan results).
[0053] The term "solvate" or "solvated" means a physical association of a compound of this invention with one or more solvent molecules. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. "Solvate" or "solvated" encompasses both solution-phase and isolable solvates. Representative solvates include, for example, hydrates, ethanolates, and methanolates.
[0054] The term "mixture" refers to the combined elements of the mixture regardless of the phase-state of the combination (e.g., liquid or liquid/ crystalline).
[0055] The term "seeding" refers to the addition of crystalline material to a solution or mixture to initiate crystallization.

It should be understood, however, that not all such information is required for one skilled in the art to determine that such particular form is present in a given composition, but that the determination of a particular form can be achieved using any portion of the characterizing information that one skilled in the art would recognize as sufficient for establishing the presence of a particular form, e.g., even a distinguishing peak can be sufficient for one skilled in the art to appreciate that such particular form is present. [0058] Certain cocrystal forms of ((l S,2S,4R)-4-{4-[(l S)-2,3-dihydro-lH-inden-l- ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-2-hydroxycyclopentyl)methyl sulfamate (Γ) have properties that make them suitable for large scale pharmaceutical formulation manufacture.

However, the particular cocrystal may also be characterized by one or more of the characteristics of the polymorph as described herein, with or without regard to referencing a particular crystalline form.
[0061] Throughout the specification and claims, when a cocrystal form of MLN4924 is identified using one or more XRPD peaks given as angle 2Θ, each of the 2Θ values is understood to mean the given value ±0.2 degrees.

[0139] Other embodiments of the invention are directed to cocrystal forms of MLN4924 characterized by a combination of the aforementioned characteristics of any of the crystalline forms discussed herein. The characterization may be by any combination of one or more of the XRPD, TGA, and DSC, described for a particular polymorph. For example, a cocrystal form of MLN4924 may be characterized by any combination of the XRPD results regarding the position of the major peaks in a XRPD scan; and/or any combination of one or more of the cell parameters derived from data obtained from a XRPD scan. A cocrystal form of MLN4924 may also be characterized by TGA determinations of the weight loss associated with a sample over a designated temperature range; and/or the temperature at which a particular weight loss transition begins. DSC determinations of the temperature associated with the maximum heat flow during a heat flow transition and/or the temperature at which a sample begins to undergo a heat flow transition may also characterize the crystalline form. Weight change in a sample and/or change in sorption/de sorption of water per molecule of anhydrous cocrystal of MLN4924 as determined by water sorption/desorption measurements over a range of relative humidity (e.g., 0% to 90%) may also characterize a cocrystal form of MLN4924.
[0140] Examples of combinations of cocrystal form characterizations using multiple analytical techniques include the location of at least one of the major peaks of a XRPD scan and the temperature associated with the maximum heat flow during one or more heat flow transitions observed by a corresponding DSC measurement; the location of at least one of the major peaks of a XRPD scan and one or more weight losses associated with a sample over a designated temperature range in a corresponding TGA measurement; the location of at least one of the major peaks of a XRPD scan, the temperature associated with the maximum heat flow during one or more heat flow transitions observed by a corresponding DSC measurement, and one or more weight losses associated with a sample over a designated temperature range in a corresponding TGA measurement; and the location of at least one of the major peaks of a XRPD scan, the temperature associated with the maximum heat flow during one or more heat flow transitions observed by a corresponding DSC measurement, one or more weight losses associated with a sample over a designated temperature range in a corresponding TGA measurement, and the change in sorption/de sorption of water per molecule of anhydrous salt as determined by water sorption/desorption measurements over a range of relative humidity. As well, each of the aforementioned examples may replace the use of the location of at least one of the major peaks of a XRPD scan with one or more cell parameters of the cocrystal form.
[0141] The combinations of characterizations that are discussed above may be used to describe any of the cocrystal forms discussed herein.
Pharmaceutical Compositions and Methods
[0142] The compound of formula (I) (MLN4924), or a crystalline form thereof, or a
solvate thereof, or a cocrystal form, is a useful inhibitor of El enzyme activity. In particular, a cocrystal form of MLN4924 is designed to be an inhibitor of NAE, UAE, and/or SAE. An inhibitor is meant to include compounds which reduce the promoting effects of El enzymes in ubl conjugation to target proteins (e.g., reduction of
ubiquitination, neddylation, sumoylation), reduce intracellular signaling mediated by ubl conjugation, and/or reduce proteolysis mediated by ubl conjugation (e.g., inhibition of cullin-dependent ubiquitination and proteolysis (e.g., the ubiquitin-proteasome pathway)). Thus, a cocrystal form of MLN4924 may be assayed for its ability to inhibit the El enzyme in vitro or in vivo, or in cells or animal models according to methods provided in further detail herein, or methods known in the art. A cocrystal form of MLN4924 may be assessed for its ability to bind or mediate El enzyme activity directly. Alternatively, the activity of a cocrystal form of MLN4924 may be assessed through indirect cellular assays, or assays measuring downstream effects of El activation to assess inhibition of downstream effects of El inhibition (e.g., inhibition of cullin- dependent ubiquitination and proteolysis). For example, activity may be assessed by detection of ubl-conjugated substrates (e.g., ubl-conjugated E2s, neddylated cullins, ubiquitinated substrates, sumoylated substrates); detection of downstream protein substrate stabilization (e.g., stabilization of p27, stabilization of IKB); detection of inhibition of UPP activity;
detection of downstream effects of protein El inhibition and substrate stabilization (e.g., reporter assays, e.g., FKB reporter assays, p27 reporter assays). Assays for assessing activities are known in the art. [0143] One embodiment of this invention relates to a pharmaceutical composition comprising a cocrystal form of MLN4924, and a pharmaceutically acceptable carrier or diluent. The pharmaceutical compositions preferably are in a form suitable for administration to a recipient subject, preferably a mammal, more preferably a human. The term "pharmaceutically acceptable carrier" is used herein to refer to a material that is compatible with the recipient subject, and is suitable for delivering an active agent to the target site without terminating the activity of the agent. The toxicity or adverse effects, if any, associated with the carrier preferably are commensurate with a reasonable risk/benefit ratio for the intended use of the active agent.
[0144] The pharmaceutical compositions can be manufactured by methods well known in the art such as conventional granulating, mixing, dissolving, encapsulating, lyophilizing, or emulsifying processes, among others. Compositions may be produced in various forms, including granules, precipitates, or particulates, powders, including freeze dried, rotary dried or spray dried powders, amorphous powders, tablets, capsules, syrup, suppositories, injections, emulsions, elixirs, suspensions or solutions. Formulations may optionally contain stabilizers, pH modifiers, surfactants, solubilizing agents,
bioavailability modifiers and combinations of these.
[0145] Pharmaceutically acceptable carriers that may be used in these compositions include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates or carbonates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes,
polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.
[0146] According to a preferred embodiment, the compositions of this invention are formulated for pharmaceutical administration to a mammal, preferably a human being. Such pharmaceutical compositions of the present invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term "parenteral" as used herein includes subcutaneous, intravenous, intraperitoneal, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intravenously, or subcutaneously. The formulations may be designed to be short-acting, fast-releasing, or long-acting. Still further, compounds can be administered in a local rather than systemic means, such as administration (e.g., by injection) at a tumor site.
[0147] Pharmaceutical formulations may be prepared as liquid suspensions or solutions using a liquid, such as, but not limited to, an oil, water, an alcohol, and combinations of these. Solubilizing agents such as cyclodextrins including beta-cyclodextrin
sulfobutylether and hydroxypropyl beta-cyclodextrin may be included. Other excipients present in the formulation include citric acid or sodium citrate. Pharmaceutically suitable surfactants, suspending agents, or emulsifying agents, may be added for oral or parenteral administration. Suspensions may include oils, such as but not limited to, peanut oil, sesame oil, cottonseed oil, corn oil and olive oil. Suspension preparation may also contain esters of fatty acids such as ethyl oleate, isopropyl myristate, fatty acid glycerides and acetylated fatty acid glycerides. Suspension formulations may include alcohols, such as, but not limited to, ethanol, isopropyl alcohol, hexadecyl alcohol, glycerol and propylene glycol. Ethers, such as but not limited to, poly(ethyleneglycol), petroleum hydrocarbons such as mineral oil and petrolatum; and water may also be used in suspension formulations.
[0148] Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in
1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of
pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation. Compounds may be formulated for parenteral administration by injection such as by bolus injection or continuous infusion. A unit dosage form for injection may be in ampoules or in multi-dose containers.
[0149] The pharmaceutical compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. In the case of tablets for oral use, carriers that are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. Coatings may be used for a variety of purposes; e.g., to mask taste, to affect the site of dissolution or absorption, or to prolong drug action. Coatings may be applied to a tablet or to granulated particles for use in a capsule.
[0150] Alternatively, the pharmaceutical compositions of this invention may be
administered in the form of suppositories for rectal administration. These may be prepared by mixing the agent with a suitable non-irritating excipient which is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.
[0151] The pharmaceutical compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.
[0152] Topical application for the lower intestinal tract may be effected in a rectal
suppository formulation (see above) or in a suitable enema formulation.
Topically-transdermal patches may also be used. For topical applications, the pharmaceutical compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene,
polyoxypropylene compound, emulsifying wax and water. Alternatively, the
pharmaceutical compositions may be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.
[0153] For ophthalmic use, the pharmaceutical compositions may be formulated as
micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with our without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutical compositions may be formulated in an ointment such as petrolatum.
[0154] The pharmaceutical compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.
[0155] The pharmaceutical compositions of this invention are particularly useful in
therapeutic applications relating to disorders as described herein (e.g., proliferation disorders, e.g., cancers, inflammatory, neurodegenerative disorders). Preferably, the composition is formulated for administration to a patient having or at risk of developing or experiencing a recurrence of the relevant disorder being treated. The term "patient", as used herein, means an animal, preferably a mammal, more preferably a human. Preferred pharmaceutical compositions are those formulated for oral, intravenous, or subcutaneous administration. However, any of the above dosage forms containing a therapeutically effective amount of a compound are well within the bounds of routine experimentation and therefore, well within the scope of the instant invention. In certain embodiments, the pharmaceutical composition may further comprise another therapeutic agent. Preferably, such other therapeutic agent is one normally administered to patients with the disorder, disease or condition being treated.
[0156] By "therapeutically effective amount" is meant an amount of compound or
composition sufficient, upon single or multiple dose administration, to cause a detectable decrease in El enzyme activity and/or the severity of the disorder or disease state being treated. "Therapeutically effective amount" is also intended to include an amount sufficient to treat a cell, prolong or prevent advancement of the disorder or disease state being treated (e.g., prevent additional tumor growth of a cancer, prevent additional inflammatory response), ameliorate, alleviate, relieve, or improve a subject's symptoms of the a disorder beyond that expected in the absence of such treatment. The amount of El enzyme inhibitor required will depend on the particular compound of the composition given, the type of disorder being treated, the route of administration, and the length of time required to treat the disorder. It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, and diet of the patient, time of administration, rate of excretion, drug combinations, the judgment of the treating physician, and the severity of the particular disease being treated. In certain aspects where the inhibitor is administered in
combination with another agent, the amount of additional therapeutic agent present in a composition of this invention typically will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably, the amount of additional therapeutic agent will range from about 50% to about 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.
[0157] One embodiment relates to a method of inhibiting or decreasing El enzyme
activity in a sample comprising contacting the sample with a cocrystal form of MLN4924, or a composition comprising a cocrystal form of MLN4924. The sample, as used herein, includes, without limitation, sample comprising purified or partially purified El enzyme, cultured cells or extracts of cell cultures; biopsied cells or fluid obtained from a mammal, or extracts thereof; and body fluid (e.g., blood, serum, saliva, urine, feces, semen, tears) or extracts thereof. Inhibition of El enzyme activity in a sample may be carried out in vitro or in vivo, in cellulo, or in situ. [0158] In another embodiment, the invention provides a method for treating a patient having a disorder, a symptom of a disorder, at risk of developing, or experiencing a recurrence of a disorder, comprising administering to the patient a pharmaceutical composition according to the invention. Treating can be to cure, heal, alleviate, relieve, alter, remedy, ameliorate, palliate, improve or affect the disorder, the symptoms of the disorder or the predisposition toward the disorder. While not wishing to be bound by theory, treating is believed to cause the inhibition of growth, ablation, or killing of a cell or tissue in vitro or in vivo, or otherwise reduce capacity of a cell or tissue {e.g., an aberrant cell, a diseased tissue) to mediate a disorder, e.g., a disorder as described herein {e.g., a proliferative disorder, e.g., a cancer, inflammatory disorder). As used herein, "inhibiting the growth" or "inhibition of growth" of a cell or tissue {e.g., a proliferative cell, tumor tissue) refers to slowing, interrupting, arresting or stopping its growth and metastases and does not necessarily indicate a total elimination of growth.
[0159] Disease applications include those disorders in which inhibition of El enzyme activity is detrimental to survival and/or expansion of diseased cells or tissue {e.g., cells are sensitive to El inhibition; inhibition of El activity disrupts disease mechanisms; reduction of El activity stabilizes protein which are inhibitors of disease mechanisms; reduction of El activity results in inhibition of proteins which are activators of disease mechanisms). Disease applications are also intended to include any disorder, disease or condition which requires effective cullin and/or ubiquitination activity, which activity can be regulated by diminishing El enzyme activity {e.g., NAE, UAE activity).
[0160] For example, methods are useful in treatment of disorders involving cellular
proliferation, including, but not limited to, disorders which require an effective cullin- dependent ubiquitination and proteolysis pathway {e.g., the ubiquitin proteasome pathway) for maintenance and/or progression of the disease state. The methods are useful in treatment of disorders mediated via proteins(e.g-., FKB activation, p27Kip activation, p21WAF/CIP1 activation, p53 activation) which are regulated by El activity(e.g., NAE activity, UAE activity, SAE activity). Relevant disorders include proliferative disorders, most notably cancers and inflammatory disorders {e.g., rheumatoid arthritis,
inflammatory bowel disease, asthma, chronic obstructive pulmonary disease (COPD), osteoarthritis, dermatosis {e.g., atopic dermatitis, psoriasis), vascular proliferative disorders {e.g., atherosclerosis, restenosis) autoimmune diseases {e.g., multiple sclerosis, tissue and organ rejection)); as well as inflammation associated with infection (e.g., immune responses), neurodegenerative disorders (e.g., Alzheimer's disease, Parkinson's disease, motor neurone disease, neuropathic pain, triplet repeat disorders, astrocytoma, and neurodegeneration as result of alcoholic liver disease), ischemic injury (e.g., stroke), and cachexia (e.g., accelerated muscle protein breakdown that accompanies various physiological and pathological states, (e.g., nerve injury, fasting, fever, acidosis, HIV infection, cancer affliction, and certain endocrinopathies)).
[0161] A cocrystal form of MLN4924 and pharmaceutical compositions are particularly useful for the treatment of cancer. As used herein, the term "cancer" refers to a cellular disorder characterized by uncontrolled or disregulated cell proliferation, decreased cellular differentiation, inappropriate ability to invade surrounding tissue, and/or ability to establish new growth at ectopic sites. The term "cancer" includes, but is not limited to, solid tumors and bloodborne tumors. The term "cancer" encompasses diseases of skin, tissues, organs, bone, cartilage, blood, and vessels. The term "cancer" further encompasses primary and metastatic cancers.
[0162] In some embodiments, the cancer is a solid tumor. Non-limiting examples of solid tumors that can be treated by the methods include pancreatic cancer; bladder cancer; colorectal cancer; breast cancer, including metastatic breast cancer; prostate cancer, including androgen-dependent and androgen-independent prostate cancer; renal cancer, including, e.g., metastatic renal cell carcinoma; hepatocellular cancer; lung cancer, including, e.g., non-small cell lung cancer (NSCLC), bronchi oloalveolar carcinoma (BAC), and adenocarcinoma of the lung; ovarian cancer, including, e.g., progressive epithelial or primary peritoneal cancer; cervical cancer; gastric cancer;
esophageal cancer; head and neck cancer, including, e.g., squamous cell carcinoma of the head and neck; melanoma; neuroendocrine cancer, including metastatic neuroendocrine tumors; brain tumors, including, e.g., glioma, anaplastic oligodendroglioma, adult glioblastoma multiforme, and adult anaplastic astrocytoma; bone cancer; and soft tissue sarcoma.
[0163] In some other embodiments, the cancer is a hematologic malignancy.
Non-limiting examples of hematologic malignancy include acute myeloid leukemia (AML); chronic myelogenous leukemia (CML), including accelerated CML and CML blast phase (CML-BP); chronic myelomonocytic leukemia (CMML); acute lymphoblastic leukemia (ALL); chronic lymphocytic leukemia (CLL); Hodgkin's disease (HD);
non-Hodgkin's lymphoma (NHL), including follicular lymphoma and mantle cell lymphoma; B-cell lymphoma; T-cell lymphoma; multiple myeloma (MM);
Waldenstrom's macroglobulinemia; myelodysplastic syndromes (MDS), including refractory anemia (RA), refractory anemia with ringed siderblasts (RARS), (refractory anemia with excess blasts (RAEB), and RAEB in transformation (RAEB-T); and myeloproliferative syndromes.
[0164] In some embodiments, the compound or composition is used to treat a patient having or at risk of developing or experiencing a recurrence in a cancer selected from the group consisting of colorectal cancer, ovarian cancer, lung cancer, breast cancer, gastric cancer, prostate cancer, and pancreatic cancer. In certain preferred embodiments, the cancer is selected from the group consisting of lung cancer, colorectal cancer, ovarian cancer and hematologic cancers.
[0165] Depending on the particular disorder or condition to be treated, in some
embodiments, the El enzyme inhibitor is administered in conjunction with additional therapeutic agent or agents. In some embodiments, the additional therapeutic agent(s) is one that is normally administered to patients with the disorder or condition being treated. As used herein, additional therapeutic agents that are normally administered to treat a particular disorder or condition are known as "appropriate for the disorder or condition being treated". The other therapeutic agent may be administered prior to, at the same time as, or following administration of the El inhibitor.
[0166] In some embodiments, a cocrystal form of MLN4924 or pharmaceutical
compositions containing a cocrystal form of MLN4924 are administered in conjunction with a therapeutic agent selected from the group consisting of cytotoxic agents, radiotherapy, and immunotherapy appropriate for treatment of proliferative disorders and cancer.

Methods of Preparing Cocrystal Forms
[0168] In some embodiments, a cocrystal form of MLN4924 can be synthesized by
cooling a solution containing dissolved MLN4924 and a coformer prepared at a specified elevated temperature. In some other embodiments, the solution is allowed to cool down to room or subambient temperature either by turning the heating device off while keeping the sample in the oil bath or on the hot plate or by removing the sample from the oil bath or hot plate. Solids were collected by vacuum filtration and analyzed.
[0169] In some embodiments, a cocrystal form of MLN4924 can be synthesized by
slurrying a suspension of MLN4924 and a coformer prepared by adding solvent such that excess solids remained. The resulting mixture is then agitated in a sealed vial at the specified temperature. After a given amount of time, the solids are isolated by vacuum filtration.
[0170] In some embodiments, a cocrystal form of MLN4924 can be synthesized by
solvent assisted grinding. Samples of MLN4924 and coformer are transferred to agate milling containers. An agate milling ball is added to the container and, a small amount of solvent is added. The milling container is then attached to a Retsch mill. The samples are milled for specific time periods at 20 Hz or 30 Hz, and the solids are scraped down the walls of the jars between milling periods. The resulting solids are transferred to clean vials and analyzed.
[0171] In some embodiments, a cocrystal form of MLN4924 can be synthesized by
solvent/anti-solvent precipitation. Solutions of MLN4924 and coformers are prepared in various solvents. An excess of an anti-solvent is added to the solution to precipitate solids. Solids are allowed to slurry at the listed time period prior to isolation by vacuum filtration.
[0172] In some embodiments, a cocrystal form of MLN4924 can be synthesized by
vapor diffusion. Solutions of MLN4924 and coformer are prepared in specified solvents in small vials. The small vial is left uncapped and placed into a larger vial containing an anti-solvent. The larger vial is capped to allow vapor diffusion to occur. Solids are collected by vacuum filtration prior to analysis.

General Methods
[0223] Crystallization Techniques: 96-Well Plate: API stock solutions were prepared at
-45 mg/mL in acetone, HFIPA, MeOH, and THF and dispensed into a 96-well plate. Coformer solutions, prepared at 0.1M concentration in methanol or methanol: water mixtures, were added at 1 : 1 or 2: 1 APLcoformer ratio. A small amount of antisolvent (ethyl acetate, heptane, IPE, toluene, or water) was also added to each well. Wells were covered with aluminum foil and a small hole placed in each well to allow for slow evaporation. The majority of the wells were observed to be oils after ~3 days of evaporation. 100 [iL of 90: 10 ethyl acetate :ethanol was added to each well and the plate was sonicated. Plate was again covered with aluminum foil with pinholes for each well and allowed to slowly evaporate. After ~2 days, the solvent was evaporated and the plate was analyzed by XRPD.
[0224] Computational Methods: Indexed XRPD Data: XRPD patterns were indexed using X-Pert High Score Plus (v.2.2.1) or proprietary SSCI software (Triads v 1.0).
Successful indexing of a pattern indicates that the sample is composed primarily of a single crystalline phase. Space groups consistent with the assigned extinction symbol, unit cell parameters, and derived quantities are tabulated in the respective figures providing the indexing solution for each form. To confirm the tentative indexing solution, the molecular packing motifs within the crystallographic unit cells must be determined. No attempts at molecular packing were performed.
[0225] X-ray Powder Diffraction Peak Identification Process: The data contain X-ray diffraction patterns with labeled peaks and tables with peak lists. Peak labels in the image are meant as a visual aid. Accurate peak positions are listed in the tables. Under most circumstances, peaks within the range of up to about 30° (2Θ) were selected. Rounding algorithms were used to round each peak to the nearest 0.1° or 0.01° (2Θ), depending upon the instrument used to collect the data and/or the inherent peak resolution. The location of the peaks along the horizontal axis, 0 (2Θ), in both the figures and the tables were automatically determined using proprietary software and rounded to one or two significant figures after the decimal point based upon the above criteria. Peak position variabilities are given to within ±0.2° (2Θ) based upon recommendations outlined in the USP discussion of variability in X-ray powder diffraction. The accuracy and precision associated with any particular measurement reported herein has not been determined. To calculate <i-spacings, the wavelength used was 1.541874 A, a weighted average of the Cu- Kal and Cu-Ka2 wavelengths. Variability associated with <i-spacing estimates was calculated from the USP recommendation, at each <i-spacing, and provided in the respective data tables. Per USP guidelines, variable hydrates and solvates may display peak variances greater than 0.2° (2Θ) and therefore peak variances of 0.2° (2Θ) are not applicable to these materials. For samples with only one XRPD pattern and no other means to evaluate whether the sample provides a good approximation of the powder average, peak tables contain data identified only as "Prominent Peaks". These peaks are a subset of the entire observed peak list. Prominent peaks are selected from observed peaks by identifying preferably non-overlapping, low-angle peaks, with strong intensity.
[0226] Nuclear Magnetic Resonance Spectroscopy (NMR): Samples were prepared in deuterated dimethyl sulfoxide (DMSO). The specific acquisition parameters are listed on the plot of the first spectrum displayed in the data section. The solution NMR spectra were acquired at ambient temperature with a Varian UNITYESTOVA-400 spectrometer at 400 MHz. For 1H-NMR, the spectra were referenced to internal tetramethylsilane (TMS) at 0.0 ppm.
[0227] Differential Scanning Calorimetry (DSC): DSC analysis was performed using a
TA Instruments differential scanning calorimeter Q2000 or 2920. The sample was placed into an aluminum DSC pan, its weight accurately recorded. In most analysis the lid was hermetically sealed and perforated with a laser pinhole. In one case a Tzero crimped pan was utilized. The sample cell was equilibrated at -30 °C and heated under a nitrogen purge at a rate of 10 °C/min, up to final temperature of 250 °C or 260 °C. Indium metal was used as the calibration standard. [0228] Thermal Gravimetric Analysis (TGA): TGA analyses were performed using a
TA Instruments 2950 thermogravimetric analyzer. Temperature calibration was performed using nickel and Alumel™ Each sample was placed in an aluminum or platinum pan and then inserted into the TG furnace. The furnace was heated under nitrogen.
[0229] High Performance Liquid Chromatography (HPLC): HPLC analyses were performed using an Agilent 1100 series liquid chromatograph equipped with a variable wavelength detector and binary pump for sequence file 552094, and a diode array detector and quaternary pump for the remaining sequences. Configurations differ due to instrument availability at the time of assay. Degasser and an autosampler (set to ~5°C) were equipped for all sequences. The chromatographic column was a 150 χ 4.6 mm Aquasil C18 column with 3 μπι packing (Thermo Scientific). The column temperature was set to 40 °C, and the detector wavelength was 280 nm with a bandwidth of 8 nm. The injection volume was 15 μΐ^. Mobile phase A was 0.1% TFA in Water, and mobile phase B was 0.1% TFA in Acetonitrile. The flow rate used was 0.5 L/minute. Mobile phases were filtered and degassed through a 0.45 μπι nylon filter under vacuum prior to use, except for Mobile phase A used in sequence file 554410 due to time constraints.

[0230] X-Ray Powder Diffraction (XRPD): Figures of XRPD patterns were generated using Pattern Match 2.3.6. XRPD patterns were collected with either PANalytical or Bruker. [0231] PANalytical : XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer either in reflection or transmission geometry. For reflection geometry, the diffractometer was configured using the symmetric Bragg-Brentano geometry and the incident beam of Cu-Κα radiation was produced using a long, fine-focus source and a nickel filter. A specimen of the sample was prepared as a thin, circular layer centered on a silicon zero-background substrate. Antiscatter slits (SS) were used to minimize the background generated by air. In transmission geometry, the diffractometer used an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu-Κα X-rays through the specimen and onto the detector. A specimen of the sample was sandwiched between 3- μιη-thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and antiscatter knife edge, were used to minimize the background generated by air. Transmission configuration was used most frequently throughout this study. For either configuration, prior to the analysis, a silicon specimen (NIST SRM 640d) was analyzed to verify the Si 1 11 peak position. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the sample and Data Collector software v. 2.2b.
[0232] Bruker: XRPD patterns were collected using a Bruker D8 DISCOVER
diffractometer and Bruker' s General Area-Detector Diffraction System (GADDS, v. 4.1.20). An incident microbeam of Cu-Κα radiation was produced using a long, fine- focus tube (40 kV, 40 mA), a parabolically graded multilayer mirror, and a 0.5 mm double-pinhole collimator. Prior to the analysis, a silicon specimen (NIST SRM 640c embedded in epoxy) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. The samples were positioned for analysis by securing the well plate to a translation stage and moving each sample to intersect the incident beam in transmission geometry. The incident beam was scanned and rastered during the analysis to optimize orientation statistics. A beam-stop was used to minimize the background from air. Diffraction patterns were collected using a HISTAR™ area detector located 15 cm from the sample and processed using GADDS. The intensity in the GADDS image of the diffraction pattern was integrated and displayed as a function of 2Θ. The instrument was operated under non-GMP conditions, and the results are non- GMP.
Example 1
Microscale Cocrystal Formation of MLN4924
[0233] A cocrystal formation of MLN4924 was performed using twenty-five coformers including acetic acid, benzoic acid, camphoric acid, caproic acid, trans-c' namic acid, ethylenediamine, fumaric acid, gentisic acid, D-glucuronic acid, glycolic acid, hippuric acid, DL-lactic acid, L-lysine, L-malic acid, malonic acid, DL-mandelic acid, meglumine, orotic acid, oxalic acid, piperazine, L-proline, L-pyroglutamic acid, saccharin, succinic acid, and vanillin. Crystallization techniques included evaporation, precipitation using an anti-solvent, slow cooling, vapor diffusion, slurrying, and liquid-assisted grinding.
MLN4924 was used as starting material for the cocrystal formation experiments. XRPD data of isolated solids were compared to the pattern of MLN4924 free base, to each other, and to the patterns of respective coformers which are solid at ambient temperature.
[0234] Cocrystal formation experiments were first conducted on microscale in a 96-well plate to test a variety of coformers, solvents, and stoichiometries. Coformers used for these experiments included acetic acid, benzoic acid, camphoric acid, caproic acid, trons- cinnamic acid, ethylenediamine, fumaric acid, D-glucuronic acid, glycolic acid, hippuric acid, DL-lactic acid, L-lysine, L-malic acid, DL-mandelic acid, piperazine, L-proline, L- pyroglutamic acid, saccharin, succinic acid, and vanillin. Mole ratios studied varied between 1 : 1 and 2: 1 MLN4924 free base to coformer. Evaporation of the initial solvent system resulted in oily material or glassy films; therefore a second solvent system was added (ethyl acetate :ethanol (90: 10)) followed by sonication. Evaporation following this step resulted in an increase in observed crystallinity based on XRPD results.

Medium Scale Cocrystal Formation of MLN4924
[0235] Medium scale experiments then followed which allowed for a wider range of experimental techniques to be employed (Table 18). Isolated solids which exhibited a unique XRPD pattern were further characterized by proton spectroscopy to determine chemical composition and stoichiometry. Thermal analysis were conducted on selected solids.
[0236] Overall, sixty single or multi-step medium scale (-50 mg to -200 mg)
experiments were performed targeting various cocrystals of MLN4924 free base. Twenty coformers were studied including mono-, di-, and aromatic carboxylic acids (acetic acid, benzoic acid, trans-cinnamic acid, fumaric acid, gentisic acid, D-glucuronic acid, glycolic acid, hippuric acid, malonic acid, DL-mandelic acid, orotic acid, oxalic acid, L- pyroglutamic acid, and succinic acid), bases (ethylenediamine, meglumine, and piperazine), amino acids (L-lysine and L-proline), and saccharin. Crystallization techniques included evaporation, cooling, vapor diffusion, precipitation with an anti- solvent, slurrying, and liquid assisted grinding. The majority of experiments were conducted using a 1 : 1, 2: 1, or 1 :2 molar ratio of MLN4924 to coformer. A few experiments were done such that a large molar excess of one of the components was present (either MLN4924 or coformer), a technique that is designed to reduce the solubility of a potential cocrystal in a given medium and thus promote its crystallization.

Non-cGMP sample
[0237] Cocrystal Form A was observed from slurrying in isopropyl acetate and from
vapor diffusion between acetone and methyl tert-butyl ether. The XRPD pattern of cocrystal Form A (FIG. 1) was successfully indexed indicating the presence of a single crystalline phase. Agreement between the allowed peak positions and the observed peaks indicates a consistent unit cell determination. Proton NMR data for cocrystal Form A (FIG. 2) are consistent with MLN4924 containing approximately one mole of gly colic acid per mole of MLN4924. Thermogravimetric data for cocrystal Form A (FIG. 4) show an about 5.3 wt% loss between about 101 °C and about 175 °C possibly related to the endothermic event as seen in the DSC thermogram and a sharp weight loss at about 216 °C, possibly attributed to decomposition. The DSC thermogram (FIG. 3) shows a minor endothermic peak at about 121.3 °C followed immediately by a sharp endothermic peak at about 138.1 °C (peak maximum), likely attributed to volatilization and decomposition or the material melting.
[0238] Cocrystal Form B was observed from only one attempt targeting a hippuric acid cocrystal. This material observed at medium scale is the same as that observed at microscale, based on XRPD results. Cocrystal Form B was isolated from a multi-step experiment involving precipitation of a p-dioxane:ethanol (5: 1) solution containing the API and coformer with heptane. A gummy, hazy solution resulted immediately upon antisolvent addition, but slurrying at ambient temperature for one day resulted in handleable solids for isolation. The XRPD pattern of cocrystal Form B (FIG. 5) was indexed with two possible solutions indicating either the presence of a single crystalline phase (monoclinic - red bars) or, more likely, a mixture of a single crystalline phase with free hippuric acid (orthorhombic - blue bars). Proton NMR data (FIG. 6) are consistent with MLN4924 containing approximately one mole of hippuric acid per mole of API. Thermogravimetric data for cocrystal Form B show negligible weight loss prior to the sharp weight loss at about 235 °C, suggesting the material is anhydrous and unsolvated (FIG. 8). The DSC thermogram shows a sharp endothermic peak at about 150.9 °C (peak maximum), possibly attributed to the material melting followed by possible
decomposition (FIG. 7).
[0239] Cocrystal Form D was observed from an attempt targeting an L-proline cocrystal from a slow evaporation experiment in acetone:MeOH:water:EtOAc. This same XRPD pattern (FIG. 10) was observed from all four microscale experiments also targeting an L- proline cocrystal. Proton NMR data (FIG. 11) indicate the presence of -0.3 moles of L- proline per mole of MLN4924.
[0240] Cocrystal Form F was observed from two experiments targeting a saccharin
cocrystal. An attempted cooling experiment in ethyl acetate and an ambient temperature slurry in ethanol both resulted in cocrystal Form F. Liquid assisted grinding with isopropyl alcohol resulted in cocrystal Form F as a mixed phase with both starting materials. The following phase and composition data are sufficient to designate this material as cocrystal Form F. The XRPD pattern of cocrystal Form F (FIG. 12) was successfully indexed indicating the presence of a single crystalline phase. Agreement between the allowed peak positions, marked with red bars, and the observed peaks indicates a consistent unit cell determination. Proton NMR data for cocrystal Form F (FIG. 13) are consistent with MLN4924 containing approximately one mole of saccharin per mole of API. Thermogravimetric data show a stepwise about 1.9 wt% loss between about 171 °C and about 200 °C and a sharp weight loss at about 219 °C likely associated with decomposition of the material (FIG. 15). The DSC thermogram shows a sharp endothermic peak at about 198.5 °C overlapping with a sharp exothermic peak at about 201.8 °C, possibly attributed to a melt/decomposition event (FIG. 14).
[0241] Cocrystal Form G was observed while targeting a piperazine cocrystal from a slow cooling experiment in acetonitrile. The XRPD pattern of cocrystal Form G (FIG. 16) was successfully indexed indicating the presence of a single crystalline phase.
Agreement between the allowed peak positions, marked with red bars, and the observed peaks indicates a consistent unit cell determination. The predicted unit cell volume based from the indexing results suggests a stoichiometry of either a 1 : 1 MLN4924: piperazine cocrystal or a 1 :2 MLN4924: acetonitrile solvate. Proton NMR data of cocrystal Form G (FIG. 17) were consistent with MLN4924 containing approximately 0.5 moles of piperazine and approximately 0.6 moles of acetonitrile per mole of API. Drying cocrystal Form G under vacuum at -38 °C for ~1 day resulted in material exhibiting a similar XRPD pattern, but more representative of disordered material based on peak broadening.
[0242] Cocrystal Form J was observed from a cooling experiment in acetonitrile, and although the material is highly crystalline based on XRPD results (FIG. 20), the proton NMR data (FIG. 21) indicate the presence of approximately one mole of gentisic acid and three moles of acetonitrile per mole of MLN4924. Drying cocrystal Form J under vacuum to remove the acetonitrile resulted in a disordered material, identified as Form L. Only residual levels of acetonitrile were detected in the proton NMR data of Form L. Two other materials (designated as Form H and Form N), exhibiting broadened peaks in the XRPD pattern, indicative of disordered material, were observed from crystallization attempts in nitromethane:ethanol (-30: 1) and isopropyl alcohol: heptane (-4: 1).
[0243] Cocrystal Form M was observed from one sample targeting a malonic acid
cocrystal. Cocrystal Form M was prepared by an attempted slow cooling experiment in nitromethane. Partial dissolution of the starting materials followed by precipitation was observed and the sample was allowed to cool slowly to ambient temperature prior to isolation. The XRPD pattern of Form M (FIG. 22) was successfully indexed indicating the presence of a single crystalline phase. Agreement between the allowed peak positions, marked with red bars, and the observed peaks indicates a consistent unit cell determination. Proton MR data (FIG. 23) are consistent with MLN4924 containing approximately one mole of malonic acid per mole of API. Thermogravimetric data of cocrystal Form M (FIG. 25) show a stepwise about 14.0 wt% loss between about 135 °C and about 184 ° C potentially due to the loss of malonic acid. A sharp weight loss at about 254 °C is also observed and likely attributable to decomposition of the material (FIG. 24). The DSC thermogram shows a sharp endotherm at about 155.1 °C (peak maximum) possibly attributed to volatilization and decomposition or the material melting.
[0244] Other Forms Observed During the Formation Experiment: A new material, designated as Form K, was isolated as a mixture with a small amount of MLN4924 free base from select experiments with ethylenediamine and L-lysine. Proton NMR data of Form K from both cocrystal experiments indicate that ethylenediamine and L-lysine are not present or only at residual levels, indicating they are not cocrystals. Although the proton NMR data are consistent with the chemical structure of MLN4924, an increase in small unknown peaks was observed, suggesting an increase in impurities. This result suggests the possibility that Form K is a polymorph of MLN4924 which may be related to the basic conditions and/or level of impurities that resulted from these experimental conditions.

Preliminary Evaluation of Selected MLN4924 Cocrystals
[0245] The aqueous solubility of new materials was estimated in water using a solvent addition method (Table 19). All new materials that were confirmed to contain a stoichiometric ratio of MLN4924 to coformer were estimated to have a solubility of less than 1 mg/mL.

All new materials, except for the solvated piperazine cocrystal (Material G), showed no propensity for deliquescence and remained free flowing solids. The solvated piperazine cocrystal became slightly tacky after exposure to ~97%> RH for approximately two days.

Scale up of Selected MLN4924 Cocrystals
[0247] Initial scale-ups were attempted for the glycolic acid, hippuric acid, malonic acid, piperazine, and saccharin cocrystals at about 200-300 mg scale with respect to MLN4924. Experimental details and results are included in Table 21. The first attempt with malonic acid and saccharin resulted in the same materials observed during the medium scale formation experiment. Two attempts to reproduce the piperazine cocrystal at larger scale were unsuccessful; one resulted in the free base and the other resulted in material exhibiting a similar XRPD pattern as Form G, but a few additional peaks were observed. These peaks were not allowed based on the indexing solution of the XRPD pattern of Form G and were not attributed to any known forms of the starting components at the time of this study. An underlying halo was also observed in the XRPD pattern of this material prepared at scale-up, suggesting the presence of disorder or amorphous content. Thermogravimetric data of this sample shows a weight loss of about 5.7% from about 24 °C to about 150 °C (Fig. 19). The DSC thermogram shows several thermal events between about 46 °C and about 166 °C. Proton MR data of this sample was consistent with MLN4924 containing about 0.5 moles of piperazine and about -0.2 moles of acetonitrile per mole of API. The NMR data suggests that the acetonitrile content of this material may be variable.

Physical and Chemical Stability Studies of Selected Cocrystals
[0248] The physical and chemical stability of the glycolic acid, hippuric acid, malonic acid, and saccharin cocrystals were evaluated at two stress conditions (60 °C/ambient relative humidity and 60 °C/75% relative humidity) and compared to MLN4924 HCl salt. These results are summarized in Table 22.
Table 22. Relative Humidity / Temperature Stressing of MLN4924 Cocrystals and HCl Salts
Figure imgf000088_0001
a. 60 °CI ambient RH, 60 °C/ 75% RH, 2 weeks.
b. Results:
HCl salt changed forms to the hydrate at 60 °C/ 75% RH;
No form changed with the cocrystals.
[0249] Physical stability was assessed by comparison of XRPD patterns of the unstressed and stressed samples. No form changes were observed for any of the cocrystals studied. However, the 2-week MLN4924-HC1 60 °C/75% RH sample was observed to have a new unique crystalline XRPD pattern suggesting a change in form may have occurred, possibly to a hydrated form.
[0250] Chemical stability was assessed via HPLC analysis of samples at t=0 and t=14 days. The initial t=0 data for the glycolic and hippuric acid samples was repeated due to poor agreement between working and check standards. This second run occurred about 1-2 days after the initial samples. [0251] The glycolic acid cocrystal and MLN4924-HC1 showed limited stability under the stressed conditions compared to the other samples. Each of these samples showed a loss of at least 3% of API area percent at one of the stressed conditions after two weeks. Of the samples tested, the malonic acid had the highest initial purity and the highest final purity in each of the stress conditions. The saccharin cocrystal had the lowest initial purity (about 91%) but did not show significant changes upon stressing. Specifically, the hippuric acid, saccharin, and malonic acid cocrystals show little decomposition under both stress conditions.
[0252] The hippuric acid, saccharin, and malonic acid cocrystals showed improvement in stability over the current MLN4924 HCl form and could be potential alternative forms for development.

Sample was stirred and heated to about 72 °C in an oil bath and a clear solution was observed. The sample was held at about 72 °C for about 30 minutes before heat was turned off and the sample was allowed to slowly cool to room temperature and stir for about 1 day. A slurry was observed. Solids were isolated via vacuum filtration.
