Description:
FIELD OF INDUSTRIAL APPLICABILITY 
     The present invention generally relates to crystalline forms of (9R,13S)-13-{4-[5-chloro-2-(4-chloro-TH-1,2,3-triazol-1-yl)phenyl]-6-oxo-1,6-dihydropyrimidin-1-yl}-3-(difluoromethyl)-9-methyl-3,4,7,15-tetraazatricyclo[12.3.1.0 2,6 ]octadeca-1(18),2(6),4,14,16-pentaen-8-one. The present invention also generally relates to pharmaceutical compositions comprising the crystalline forms, as well as methods of using the crystalline forms in the treatment of thromboembolic disorders, and methods for obtaining such crystalline forms. 
     BACKGROUND OF THE INVENTION 
     Factor XIa is a plasma serine protease involved in the regulation of blood coagulation, which is initiated in vivo by the binding of tissue factor (TF) to factor VII (FVII) to generate factor VIIa (FVIIa). The resulting TF:FVIIa complex activates factor IX (FIX) and factor X (FX) that leads to the production of factor Xa (FXa). The generated FXa catalyzes the transformation of prothrombin into small amounts of thrombin before this pathway is shut down by tissue factor pathway inhibitor (TFPI). The process of coagulation is then further propagated via the feedback activation of Factors V, VIII and XI by catalytic amounts of thrombin. (Gailani, D. et al.,  Arterioscler. Thromb. Vasc. Biol.,  27:2507-2513 (2007).) The resulting burst of thrombin converts fibrinogen to fibrin that polymerizes to form the structural framework of a blood clot, and activates platelets, which are a key cellular component of coagulation (Hoffman, M.,  Blood Reviews,  17:S1-S5 (2003)). Therefore, factor XIa plays a key role in propagating this amplification loop and is thus an attractive target for anti-thrombotic therapy. 
     The compound, (9R,13S)-13-{4-[5-chloro-2-(4-chloro-TH-1,2,3-triazol-1-yl)phenyl]-6-oxo-1,6-dihydropyrimidin-1-yl}-3-(difluoromethyl)-9-methyl-3,4,7,15-tetraazatricyclo[12.3.1.0 2,6 ]octadeca-1(18),2(6),4,14,16-pentaen-8-one, has the structure: 
     
       
         
         
             
             
         
       
     
     and is referred to herein as “Compound (I)”. Compound (I), a process to prepare Compound (I), and methods of treatment employing Compound (I) are disclosed in U.S. Patent Application Publication No. 2016/0096839 (hereinafter referred to as the &#39;839 publication), which is incorporated herein by reference in its entirety. In Example 88, the &#39;839 publication discloses the synthesis of Compound (I). By the embodiments exemplified below, crystalline forms of Compound (I) can be obtained. 
     Compound (I) is useful for treating thromboembolic disorders. However, before Compound (I) is used to treat diseases in patients, it must be formulated into a pharmaceutical composition that can be administered to the patient; for example, into a dosage form suitable for oral, mucosal, parenteral, or transdermal administration. Formulations for oral administration are preferred since they are more convenient and easier to administer than other formulations. Also, the oral route of administration avoids the pain and discomfort of parenteral administration. Accordingly, formulations for oral administration are preferred by patients, and typically result in better patient compliance with dosing schedules. 
     Typically, in preparing a pharmaceutical composition, a form of the active ingredient is sought that has a balance of desired properties, such as, for example, dissolution rate, solubility, bioavailability, and/or storage stability. For example, a form of the active ingredient is sought having sufficient stability, solubility, and bioavailability to prevent the sufficiently soluble and bioavailable form from converting during the manufacture, preparation, and/or storage of the pharmaceutical composition to another form having an undesirable solubility and/or bioavailability profile. In addition, a form of the active ingredient may also be sought that permits the active ingredient to be isolated and/or purified during, for example, a preparative process. 
     Active pharmaceutical ingredients can exist in different physical forms (e.g., liquid or solid in different crystalline, amorphous, hydrate, or solvate forms), which can vary the processability, stability, solubility, bioavailability, pharmacokinetics (e.g. absorption, distribution, metabolism, excretion, or the like), and the pharmaceutical compositions comprising it. It is unpredictable whether a compound will exist in a particular polymorph form, how many such forms might exist for a particular compound (or salt form), what process might produce these forms, and what properties the particular polymorph might demonstrate. It is important in pharmaceutical development to generate and identify advantageous physical forms (e.g., free base or salt in solid, liquid, crystalline, hydrate, solvate, or amorphous forms) of active pharmaceutical ingredients. Therefore, there remains a need for particular polymorph forms of Compound (I). 
     The present invention provides at least one form of Compound (I) that surprisingly affords a balance of properties sought in a pharmaceutical composition. The present invention is also directed to other important aspects. 
     SUMMARY OF THE INVENTION 
     The present invention provides crystalline forms of Compound (I). Embodiments of these crystalline forms include those characterized herein as Form A, Form B, Form C, Form D, Form E, Form F, Form G, Form H, Form I, and Form J. The names used herein to characterize a specific form, e.g. “Form A” etc., should not be considered limiting with respect to any other substance possessing similar or identical physical and chemical characteristics, but rather it should be understood that these designations are mere identifiers that should be interpreted according to the characterization information also presented herein.

     DETAILED DESCRIPTION OF THE INVENTION 
     The features and advantages of the invention may be more readily understood by those of ordinary skill in the art upon reading the following detailed description. It is to be appreciated that certain features of the invention that are, for clarity reasons, described above and below in the context of separate embodiments, may also be combined to form a single embodiment. Conversely, various features of the invention that are, for brevity reasons, described in the context of a single embodiment, may also be combined so as to form sub-combinations thereof. 
     All numbers expressing quantities of ingredients, weight percentages, temperatures, and so forth that are preceded by the word “about” are to be understood as only approximations so that slight variations above and below the stated number may be used to achieve substantially the same results as the stated number. Accordingly, unless indicated to the contrary, numerical parameters preceded by the word “about” are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. 
     All measurements are subject to experimental error and are within the spirit of the invention. 
     As used herein, “hydrate” refers to a crystalline form of a molecule that further comprises water incorporated into the crystalline structure. The water molecules in the hydrate may be present in a regular arrangement and/or a non-ordered arrangement. The hydrate may comprise either a stoichiometric or nonstoichiometric amount of the water molecules, for example, monohydrate, hemihydrate, or a mixture thereof.

     As used herein, a “free base neat crystalline form” of Compound (I) is a parent form (that is, not a salt form) of Compound (I) that is substantially pure and is not solvated or hydrated. 
     As used herein, a PXRD pattern “comprising” a number of peaks selected from a specified group of peaks, is intended to include PXRD patterns having additional peaks that are not included in the specified group of peaks. For example, a PXRD pattern comprising four or more, preferably five or more, 2θ values selected from: A, B, C, D, E, F, G, H, I, and J, is intended to include a PXRD pattern having: (a) four or more, preferably five or more, 2θ values selected from: A, B, C, D, E, F, G, H, I, and J; and (b) zero or more peaks that are not one of peaks A, B, C, D, E, F, G, H, I, and J. 
     The presence of reaction impurities and/or processing impurities may be determined by analytical techniques known in the art, such as, for example, chromatography, nuclear magnetic resonance spectroscopy, mass spectrometry, and/or infrared spectroscopy.

In one embodiment, the crystalline form is selected from a group consisting of Form F and Form J. 
     Compound (I) may be prepared in accordance with Example 1. Crystalline forms may be prepared by a variety of methods, including for example, crystallization or recrystallization from a suitable solvent, sublimation, growth from a melt, solid state transformation from another phase, crystallization from a supercritical fluid, and jet spraying. Techniques for crystallization or recrystallization of crystalline forms from a solvent mixture include, for example, evaporation of the solvent, decreasing the temperature of the solvent mixture, crystal seeding a supersaturated solvent mixture of the molecule and/or salt, freeze drying the solvent mixture, and addition of antisolvents (countersolvents) to the solvent mixture. High throughput crystallization techniques may be employed to prepare crystalline forms including polymorphs. 
     Crystals of drugs, methods of preparation, and characterization of drug crystals are discussed in  Solid - State Chemistry of Drugs , S. R. Byrn, R. R. Pfeiffer, and J. G. Stowell, 2 nd  Edition, SSCI, West Lafayette, Ind. (1999). 
     For crystallization techniques that employ solvent, the choice of solvent or solvents is typically dependent upon one or more factors, such as solubility of the compound, crystallization technique, and vapor pressure of the solvent. Combinations of solvents may be employed, for example, the compound may be solubilized into a first solvent to afford a solution, followed by the addition of an antisolvent to decrease the solubility of the compound in the solution and to afford the formation of crystals. An antisolvent is a solvent in which the compound has low solubility. 
     In one method to prepare crystals, a compound is suspended and/or stirred in a suitable solvent to afford a slurry, which may be heated to promote dissolution. The term “slurry”, as used herein, means a saturated solution of the compound, which may also contain an additional amount of the compound to afford a heterogeneous mixture of the compound and a solvent at a given temperature. 
     Seed crystals may be added to any crystallization mixture to promote crystallization. Seeding may be employed to control growth of a particular polymorph or to control the particle size distribution of the crystalline product. Accordingly, calculation of the amount of seeds needed depends on the size of the seed available and the desired size of an average product particle as described, for example, in “Programmed Cooling of Batch Crystallizers,” J. W. Mullin and J. Nyvlt,  Chemical Engineering Science,  1971, 26, 369-377. In general, seeds of small size are needed to control effectively the growth of crystals in the batch. Seed of small size may be generated by sieving, milling, or micronizing of large crystals, or by micro-crystallization of solutions. Care should be taken that milling or micronizing of crystals does not result in any change in crystallinity form the desired crystal form (i.e., change to amorphous or to another crystalline form). 
     A cooled crystallization mixture may be filtered under vacuum, and the isolated solids may be washed with a suitable solvent, such as cold recrystallization solvent, and dried under a nitrogen purge to afford the desired crystalline form. The isolated solids may be analyzed by a suitable spectroscopic or analytical technique, such as solid state nuclear magnetic resonance, differential scanning calorimetry, powder x-ray diffraction, or the like, to assure formation of the preferred crystalline form of the product. The resulting crystalline form is typically produced in an amount of greater than about 70 weight % isolated yield, preferably greater than 90 weight % isolated yield, based on the weight of the compound originally employed in the crystallization procedure. The product may be comilled or passed through a mesh screen to delump the product, if necessary. 
     Crystalline forms may be prepared directly from the reaction medium of the final process for preparing Compound (I). This may be achieved, for example, by employing in the final process step a solvent or a mixture of solvents from which Compound (I) may be crystallized. Alternatively, crystalline forms may be obtained by distillation or solvent addition techniques. Suitable solvents for this purpose include, for example, the aforementioned nonpolar solvents and polar solvents, including protic polar solvents such as alcohols, and aprotic polar solvents such as ketones. 
     The presence of more than one crystalline form in a sample may be determined by techniques such as powder x-ray diffraction (PXRD) or solid-state nuclear magnetic resonance spectroscopy. For example, the presence of extra peaks in the comparison of an experimentally measured PXRD pattern with a simulated PXRD pattern may indicate more than one crystalline form in the sample. The simulated PXRD may be calculated from single crystal x-ray data. see Smith, D. K., “ A FORTRAN Programfor Calculating X - Ray Powder Diffraction Patterns ,” Lawrence Radiation Laboratory, Livermore, Calif., UCRL-7196 (April 1963). 
     The forms of Compound (I) according to the invention may be characterized using various techniques, the operation of which are well known to those of ordinary skill in the art. The forms may be characterized and distinguished using single crystal x-ray diffraction, which is based on unit cell measurements of a single crystal at a fixed analytical temperature. A detailed description of unit cells is provided in Stout &amp; Jensen, X-Ray Structure Determination: A Practical Guide, Macmillan Co., New York (1968), Chapter 3, which is herein incorporated by reference. Alternatively, the unique arrangement of atoms in spatial relation within the crystalline lattice may be characterized according to the observed fractional atomic coordinates. Another means of characterizing the crystalline structure is by powder x-ray diffraction analysis in which the diffraction profile is compared to a simulated profile representing pure powder material, both run at the same analytical temperature, and measurements for the subject form characterized as a series of 2θ values (usually four or more). 
     Other means of characterizing the form may be used, such as solid-state nuclear magnetic resonance (ssNMR), differential scanning calorimetry, thermography and gross examination of the crystalline morphology. These parameters may also be used in combination to characterize the subject form. 
     Utility 
     The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful in inhibiting Factor XIa. Accordingly, the present invention provides methods for the treatment and/or prevention of thromboembolic disorders in mammals (i.e., factor XIa-associated disorders). 
     The crystalline forms of Compound (I) and pharmaceutical compositions thereof, in any of the methods herein, may be used to prevent thrombotic events in diverse patient populations including patients with renal and/or hepatic diseases. The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful for treating a patient who is suffering from a disorder, including and may not be limited to acute coronary syndrome, chronic coronary syndrome, deep vein thrombosis, unstable angina, myocardial infarction, atrial fibrillation, ischemic stroke, peripheral occlusive arterial disease, transient ischemic attack, secondary stroke prevention, or pulmonary embolism. The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful for use in methods for the treatment and/or prophylaxis of a patient who suffers from unstable angina, an acute coronary syndrome, atrial fibrillation, first myocardial infarction, recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, and thrombosis resulting from medical implants, devices, or procedures in which blood is exposed to an artificial surface that promotes thrombosis. The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful for use in methods for the treatment and/or prophylaxis of a patient who suffers from acute coronary syndrome, deep vein thrombosis, chronic coronary syndrome, or secondary stroke prevention. 
     The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful for prophylaxis of a patient of venous thromboembolism in acutely ill medical patients at risk for thromboembolic complication not at high risk of bleeding, or deep vein thrombosis which may lead to pulmonary embolism in patients undergoing knee or hip replacement surgery. The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful in application to reduce the risk of major cardiovascular events (cardiovascular death, myocardial infarction and stroke) in patients with chronic coronary artery disease or peripheral artery disease. The crystalline forms of Compound (I) and pharmaceutical compositions thereof may be useful in application to reduce the risk of recurrence of deep vein thrombosis and/or pulmonary embolism (PE) or stroke in patients with nonvalvular atrial fibrillation. 
     The crystalline forms of Compound (I) described herein may be formulated into pharmaceutical compositions and/or employed in therapeutic and/or prophylactic methods, wherein the crystalline compound (I) has a crystalline form selected from: Form A, Form B, Form C, Form D, Form E, Form F, Form G, Form H, Form I, Form J, or combinations thereof. These methods include, but are not limited to, the administration of the crystalline compound (I), alone or in combination with one or more other pharmaceutically active agents, including agents that may be useful in the treatment of the disorders mentioned herein, wherein the crystalline compound (I) has a crystalline form selected from: Form A, Form B, Form C, Form D, Form E, Form F, Form G, Form H, Form I, Form J, or combinations thereof. 
     “Therapeutically effective amount” is intended to include an amount of the crystalline forms of Compound (I) that is effective when administered alone or in combination to inhibit factor XIa. If Compound (I) is used in combination with another medication, the combination of compounds described herein may result in a synergistic combination. Synergy, as described for example by Chou et al.,  Adv. Enzyme Regul.,  22:27-55 (1984), occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at suboptimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased antithrombotic effect, or some other beneficial effect of the combination compared with the individual components. 
     As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state. 
     As used herein, “prophylaxis” is the protective treatment of a disease state to reduce and/or minimize the risk and/or reduction in the risk of recurrence of a disease state by administering to a patient a therapeutically effective amount of at least one of the compounds of the present invention or a or a stereoisomer, a tautomer, a pharmaceutically acceptable salt, or a solvate thereof. Patients may be selected for prophylaxis therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. For prophylaxis treatment, conditions of the clinical disease state may or may not be presented yet. “Prophylaxis” treatment can be divided into (a) primary prophylaxis and (b) secondary prophylaxis. Primary prophylaxis is defined as treatment to reduce or minimize the risk of a disease state in a patient that has not yet presented with a clinical disease state, whereas secondary prophylaxis is defined as minimizing or reducing the risk of a recurrence or second occurrence of the same or similar clinical disease state. 
     As used herein, “prevention” covers the preventive treatment of a subclinical disease-state in a mammal, particularly in a human, aimed at reducing the probability of the occurrence of a clinical disease-state. Patients are selected for preventative therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. 
     As used herein, “risk reduction” covers therapies that lower the incidence of development of a clinical disease state. As such, primary and secondary prevention therapies are examples of risk reduction. 
     In general, a thromboembolic disorder is a circulatory disease caused by blood clots (i.e., diseases involving fibrin formation, platelet activation, and/or platelet aggregation). The term “thromboembolic disorders” as used herein includes arterial cardiovascular thromboembolic disorders, venous cardiovascular thromboembolic disorders, and thromboembolic disorders in the chambers of the heart. The term “thromboembolic disorders” as used herein also includes specific disorders selected from, but not limited to, unstable angina or other acute coronary syndromes, atrial fibrillation, first or recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, and thrombosis resulting from (a) prosthetic valves or other implants, (b) indwelling catheters, (c) stents, (d) cardiopulmonary bypass, (e) hemodialysis, or (f) other procedures in which blood is exposed to an artificial surface that promotes thrombosis. It is noted that thrombosis includes occlusion (e.g., after a bypass) and reocclusion (e.g., during or after percutaneous transluminal coronary angioplasty). The thromboembolic disorders may result from conditions including but not limited to atherosclerosis, surgery or surgical complications, prolonged immobilization, arterial fibrillation, congenital thrombophilia, cancer, diabetes, effects of medications or hormones, and complications of pregnancy. The anticoagulant effect of compounds of the present invention is believed to be due to inhibition of factor XIa or thrombin. 
     The methods preferably comprise administering to a patient a pharmaceutically effective amount of the novel crystals of the present invention, preferably in combination with one or more pharmaceutically acceptable carriers and/or excipients. The relative proportions of active ingredient and carrier and/or excipient may be determined, for example, by the solubility and chemical nature of the materials, chosen route of administration and standard pharmaceutical practice. 
     The crystalline forms of Compound (I) may be administered to a patient in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. They may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. They may be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. 
     The dosage regimen for the crystalline forms of Compound (I) will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient, and the effect desired. A physician or veterinarian can determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the thromboembolic disorder. Obviously, several unit dosage forms may be administered at about the same time. The dosage of the crystalline form of Compound (I) that will be most suitable for prophylaxis or treatment may vary with the form of administration, the particular crystalline form of the compound chosen and the physiological characteristics of the particular patient under treatment. Broadly, small dosages may be used initially and, if necessary, increased by small increments until the desired effect under the circumstances is reached. 
     By way of general guidance, in the adult, suitable doses may range from about 0.001 to about 1000 mg/kg body weight, and all combinations and subcombinations of ranges and specific doses therein. Preferred doses may be from about 0.01 to about 100 mg/kg body weight per day by inhalation, preferably 0.1 to 70, more preferably 0.5 to 20 mgkKg body weight per day by oral administration, and from about 0.01 to about 50, preferably 0.01 to 10 mg/kg body weight per day by intravenous administration. In each particular case, the doses may be determined in accordance with the factors distinctive to the subject to be treated, such as age, weight, general state of health and other characteristics which can influence the efficacy of the medicinal product. The crystalline forms of Compound (I) may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily. 
     For oral administration in solid form such as a tablet or capsule, the crystalline forms of Compound (I) can be combined with a non-toxic, pharmaceutically acceptable inert carrier, such as lactose, starch, sucrose, glucose, methylcellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like. 
     Preferably, in addition to the active ingredient, solid dosage forms may contain a number of additional ingredients referred to herein as “excipients”. These excipients include among others diluents, binders, lubricants, glidants and disintegrants. Coloring agents may also be incorporated. “Diluents”, as used herein, are agents which impart bulk to the formulation to make a tablet a practical size for compression. Examples of diluents are lactose and cellulose. “Binders”, as used herein, are agents used to impart cohesive qualities to the powered material to help ensure the tablet will remain intact after compression, as well as improving the free-flowing qualities of the powder. Examples of typical binders are lactose, starch and various sugars. “Lubricants”, as used herein, have several functions including preventing the adhesion of the tablets to the compression equipment and improving the flow of the granulation prior to compression or encapsulation. Lubricants are in most cases hydrophobic materials. Excessive use of lubricants is undesired, however, as it may result in a formulation with reduced disintegration and/or delayed dissolution of the drug substance. “Glidants”, as used herein, refer to substances which may improve the flow characteristics of the granulation material. Examples of glidants include talc and colloidal silicon dioxide. “Disintegrants”, as used herein, are substances or a mixture of substances added to a formulation to facilitate the breakup or disintegration of the solid dosage form after administration. Materials that may serve as disintegrants include starches, clays, celluloses, algins, gums and cross-linked polymers. A group of disintegrants referred to as “super-disintegrants” generally are used at a low level in the solid dosage form, typically 1% to 10% by weight relative to the total weight of the dosage unit. Croscarmellose, crospovidone and sodium starch glycolate represent examples of a cross-linked cellulose, a cross-linked polymer and a cross-linked starch, respectively. Sodium starch glycolate swells seven- to twelve-fold in less than 30 seconds effectively disintegrating the granulations that contain it. 
     The disintegrant preferably used in the present invention is selected from the group comprising modified starches, croscarmellose sodium, carboxymethylcellulose calcium and crospovidone. A more preferred disintegrant in the present invention is a modified starch such as sodium starch glycolate. 
     Preferred carriers include capsules or compressed tablets which contain the solid pharmaceutical dosage forms described herein. Preferred capsule or compressed tablet forms generally comprise a therapeutically effective amount of the crystalline forms of Compound (I) and one or more disintegrants in an amount greater than about 10% by weight relative to the total weight of the contents of the capsule or the total weight of the tablet. 
     Preferred capsule formulations may contain the crystalline forms of Compound (I) in an amount from about 5 to about 1000 mg per capsule. Preferred compressed tablet formulations contain the crystalline forms of Compound (I) in an amount from about 5 mg to about 800 mg per tablet. More preferred formulations contain about 50 to about 200 mg per capsule or compressed tablet. Preferably, the capsule or compressed tablet pharmaceutical dosage form comprises a therapeutically effective amount of Forms A and B of Compound (I); a surfactant; a disintegrant; a binder; a lubricant; and optionally additional pharmaceutically acceptable excipients such as diluents, glidants and the like; wherein the disintegrant is selected from modified starches; croscarmellose sodium, carboxymethylcellulose calcium and crospovidone. 
     For oral administration in liquid form, the crystalline forms of Compound (I) can be combined with any oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. The liquid composition may contain a sweetening agent which to make the compositions more palatable. The sweetening agent can be selected from a sugar such as sucrose, mannitol, sorbitol, xylitol, lactose, etc. or a sugar substitute such as cyclamate, saccharin, aspartame, etc. If sugar substitutes are selected as the sweetening agent the amount employed in the compositions of the invention will be substantially less than if sugars are employed. Taking this into account, the amount of sweetening agent may range from about 0.1 to about 50% by weight, and all combinations and subcombinations of ranges and specific amounts therein. Preferred amounts range from about 0.5 to about 30% by weight. 
     The more preferred sweetening agents are the sugars and particularly sucrose. The particle size of the powdered sucrose used has been found to have a significant influence in the physical appearance of the finished composition and its ultimate acceptance for taste. The preferred particle size of the sucrose component when used is in the range of from 200 to less than 325 mesh US Standard Screen, and all combinations and subcombinations of ranges and specific particle sizes therein. 
     Sterile injectable solutions may be prepared by incorporating the crystalline forms of Compound (I) in the required amounts, in the appropriate solvent, with various of the other ingredients enumerated herein, as required, followed by filtered sterilization. Generally, dispersions may be prepared by incorporating the sterilized active ingredient into a sterile vehicle which contains the dispersion medium and any other required ingredients. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation may include vacuum drying and the freeze drying technique which may yield a powder of the active ingredient, plus any additional desired ingredient from the previously sterile-filtered solution thereof. 
     All forms of the present invention may be used for the preparation of liquid formulations in which Compound (I) may be, for example, dissolved or suspended. When dissolved, Compound (I) loses its crystalline structure, and is therefore considered to be a solution of Compound (I). In addition, the crystalline forms of Compound (I) may be incorporated into solid formulations. 
     The liquid compositions may also contain other components routinely utilized in formulating pharmaceutical compositions. One example of such components is lecithin. Its use in compositions of the invention as an emulsifying agent in the range of from 0.05 to 1% by weight, and all combinations and subcombinations of ranges and specific amounts therein. More preferably, emulsifying agents may be employed in an amount of from about 0.1 to about 0.5% by weight. Other examples of components that may be used are antimicrobial preservatives, such as benzoic acid or parabens; suspending agents, such as colloidal silicon dioxide; antioxidants; topical oral anesthetics; flavoring agents; and colorants. 
     The selection of such optional components and their level of use in the compositions of the invention is within the level of skill in the art and will be even better appreciated from the working examples provided hereinafter. 
     The crystalline forms of Compound (I) may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidine pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethyl-aspartamidephenol or polyethylene oxide-polylysine substituted with palmitolyl residues. Furthermore, the crystalline Compound (I) may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacrylates and crosslinked or amphipathic block copolymers of hydrogels. 
     Gelatin capsules of the crystalline forms of Compound (I) may contain the crystalline Compound (I) and the liquid or solid compositions described herein. Gelatin capsules may also contain powdered carriers such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Tablets can be sugar coated or film coated to mask any unpleasant taste and to protect the tablet from the atmosphere or enteric coated for selective disintegration in the gastrointestinal track. 
     In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols, such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral solutions are prepared by dissolving the crystalline Compound (I) in the carrier and, if necessary, adding buffering substances. Anti-oxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid either alone or combined, are suitable stabilizing agents. Citric acid and its salts and sodium EDTA may also be employed. Parenteral solutions may also contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben and chlorobutanol. 
     Suitable pharmaceutical carriers are described in  Remington&#39;s Pharmaceutical Sciences , Mack Publishing Co., the disclosures of which are hereby incorporated herein by reference, in their entireties. Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows: 
     The preferred crystalline form of Compound (I) may serve as component (a) of this invention and can independently be in any dosage form, such as those described above, and can also be administered in various combinations, as described above. In the following description component (b) is to be understood to represent one or more agents as described herein suitable for combination therapy. 
     Accordingly, components (a) and (b) of the present invention may be formulated together, in a single dosage unit (that is, combined together in one capsule, tablet, powder, or liquid, etc.) as a combination product. When component (a) and (b) are not formulated together in a single dosage unit, the component (a) may be administered at the same time as component (b) or in any order; for example component (a) of this invention may be administered first, followed by administration of component (b), or they may be administered in the reverse order. If component (b) contains more than one agent, these agents may be administered together or in any order. When not administered at the same time, preferably the administration of component (a) and (b) occurs less than about one hour apart. Preferably, the route of administration of component (a) and (b) is oral. Although it may be preferable that component (a) and component (b) both be administered by the same route (that is, for example, both orally) or dosage form, if desired, they may each be administered by different routes (that is, for example, one component of the combination product may be administered orally, and another component may be administered intravenously) or dosage forms. 
     Thus, the crystalline forms of Compound (I) may be used alone or in combination with other diagnostic, anticoagulant, antiplatelet, fibrinolytic, antithrombotic, and/or profibrinolytic agents. For example, adjunctive administration of Factor XIa inhibitors with standard heparin, low molecular weight heparin, direct thrombin inhibitors (i.e., hirudin), aspirin, fibrinogen receptor antagonists, streptokinase, urokinase and/or tissue plasminogen activator may result in improved antithrombotic or thrombolytic efficacy or efficiency. The crystals described herein may be administered to treat thrombotic complications in a variety of animals, such as primates, including humans, sheep, horses, cattle, pigs, dogs, rats and mice. Inhibition of Factor XIa may be useful not only in the anticoagulant therapy of individuals having thrombotic conditions, but also when inhibition of blood coagulation may be required, such as to prevent coagulation of stored whole blood and to prevent coagulation in other biological samples for testing or storage. Thus, any Factor XIa inhibitor, including the crystalline forms of Compound (I) as described herein, can be added to or contacted with any medium containing or suspected of containing Factor XIa and in which it may be desired to inhibit blood coagulation. 
     The crystalline forms of Compound (I) may be used in combination with any antihypertensive agent or cholesterol or lipid regulating agent, or concurrently in the treatment of restenosis, atherosclerosis or high blood pressure. Some examples of agents that may be useful in combination with a novel form of Compound (I) according to the present invention in the treatment of high blood pressure include, for example, compounds of the following classes: beta-blockers, ACE inhibitors, calcium channel antagonists and alpha-receptor antagonists. Some examples of agents that may be useful in combination with a compound according to the invention in the treatment of elevated cholesterol levels or disregulated lipid levels include compounds known to be HMGCoA reductase inhibitors, or compounds of the fibrate class. 
     In some embodiments, for any of the pharmaceutical composition described herein, the crystalline compound (I) has a crystalline form selected from: Form A, Form B, Form C, Form D, Form E, Form F, Form G, Form H, Form I, Form J, or combinations thereof.

In some embodiments, for any of the pharmaceutical composition described herein, the crystalline compound (I) comprises crystalline Form A. In some embodiments, for any of the pharmaceutical composition described herein, the crystalline compound (I) comprises crystalline Form F. In some embodiments, for any of the pharmaceutical composition described herein, the crystalline compound (I) comprises crystalline Form J. 
     In some embodiments, for any of the method described herein, the crystalline compound (I) has a crystalline form selected from: Form A, Form B, Form C, Form D, Form E, Form F, Form G, Form H, Form I, Form J, or combinations thereof. In some embodiments, for any of the method described herein, the crystalline compound (I) has a crystalline form selected from: Form A, Form F, Form J, or combinations thereof. In some embodiments, for any of the method described herein, the crystalline compound (I) has a crystalline form selected from: Form F, Form J, or combinations thereof. In some embodiments, for any of the method described herein, the crystalline compound (I) comprises crystalline Form A. In some embodiments, for any of the method described herein, the crystalline compound (I) comprises crystalline Form F. In some embodiments, for any of the method described herein, the crystalline compound (I) comprises crystalline Form J. 
     Pharmaceutical kits which may be useful for the treatment of various disorders, and which comprise a therapeutically effective amount of a pharmaceutical composition comprising a novel form of Compound (I) in one or more sterile containers, are also within the ambit of the present invention. The kits may further comprise conventional pharmaceutical kit components which will be readily apparent to those skilled in the art, once armed with the present disclosure. Sterilization of the container may be carried out using conventional sterilization methodology well known to those skilled in the art. 
     The present invention is further described in the following examples. All of the examples are actual examples. These examples are not to be construed as limiting the scope of the appended claims. 
     EXAMPLES 
     The following examples are provided to further aid in understanding the embodiments disclosed in the application, and presuppose an understanding of conventional methods well known to those persons having ordinary skill in the art to which the examples pertain. The particular materials and conditions described hereunder are intended to exemplify particular aspects of embodiments disclosed herein and should not be construed to limit the reasonable scope thereof. 
     The crystalline forms of (9R,13S)-13-{4-[5-chloro-2-(4-chloro-1H-1,2,3-triazol-1-yl)phenyl]-6-oxo-1,6-dihydropyrimidin-1-yl}-3-(difluoromethyl)-9-methyl-3,4,7,15-tetraazatricyclo[12.3.1.0 2,6 ]octadeca-1(18),2(6),4,14,16-pentaen-8-one were characterized by various analytical techniques, including powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), dynamic vapor sorption (DVS), and thermographic analysis (TGA) using the procedures described below. 
     General Procedures 
     Primary Polymorphism Screen 
     A primary polymorphism screen was carried out in different solvent systems and utilized temperature cycling, crash cooling, evaporation and anti-solvent addition. The solvent systems were selected based on the results of the approximate solubility screen to include solvent system where new PXRD patterns were observed, solubility was observed to include process relevant solvents. Where new PXRD patterns were identified, the solids were analyzed by TG/DTA, DSC, FT-IR and  1 H NMR (where material amounts allowed). 
     Saturated Solution Experiments 
     (i) Crash Cooling 
     Saturated mother liquor solutions were placed in a refrigerator at 4° C. for ca. 5 days. Any solids recovered were analyzed by PXRD. Where no solids or an insufficient amount of solid for analysis was evident, the solutions were placed in a freezer at −18° C. for 2 days. Any solids were isolated and analyzed by PXRD. PXRD analysis was repeated on drying at 40° C. for ca. 16 h. 
     (ii) Evaporation 
     Saturated solutions were allowed to evaporate at ambient temperature and pressure. The solids obtained were analyzed by PXRD. The solids were then dried at 40° C. for ca. 16 h and re-analyzed by PXRD. 
     (iii) Anti-Solvent Addition 
     Anti-solvent was added to the saturated mother liquor solutions at 55° C. Anti-solvent was added dropwise. The solids obtained were isolated via centrifuge filtration (0.22 μm nylon filter) immediately after the addition of anti-solvent was complete. The isolated solids were analyzed by PXRD then re-analyzed after drying at 40° C. for ca. 16 h. 
     Competitive Slurry Experiments 
     Competitive slurry experiments are a solution-mediated process that provides a pathway for the less soluble (more stable) crystal to grow at the expense of the more soluble crystal form (Bernstein, J. Polymorphism in Molecular Crystals. Clarendon Press, Oxford, 2006; Brittain, H. G., Polymorphism in Pharmaceutical Solids. Marcel Dekker, Inc., New York, 1999). The choice of solvent affects the kinetics of polymorph conversion and not the thermodynamic relationship between polymorphic forms (Gu, C. H., Young, V. Jr., Grant, D. J., J. Pharm. Sci. 2001, 90 (11), 1878-1890). 
     Competitive slurry experiments can be carried out in order to locate the most stable form at the conditions investigated. Exemplary solvent systems that can be used for competitive slurry experiments are listed in Table 1.

     Powder X-Ray Diffraction (PXRD) 
     PXRD data were collected using a Bruker C2 (GADDS) General Area Detector Diffraction System (Bruker-Madison, Wis.). The radiation was Cu Ku (40 KV, 40 mA). The sample-detector distance was 15 cm. Samples were placed in sealed glass capillaries with diameters of &lt;1 mm. The capillary was rotated during data collection. Transmission data were collected for approximately in the range of 2 to 32 degrees 2θ with a sample exposure time of at least 1000 s. The resulting two-dimensional diffraction arcs were integrated to create a traditional 1-dimensional PXRD pattern with a step size of 0.05 degrees. Alternatively, PXRD analysis was carried out on a PANalytical X&#39;pert pro with PIXcel detector (128 channels), scanning the samples between 3 and 35° 20. The material was gently compressed and loaded onto a multi-well plate with Mylar polymer film to support the sample. The multi-well plate was then placed into the diffractometer and analyzed using Cu K radiation (α1 λ=1.54060 ∈; α2=1.54443 ∈; β=1.39225 ∈; α1:α2 ratio=0.5) running in transmission mode (step size 0.01300 2θ, step time 18.87 s) using 40 kV/40 mA generator settings. 
     Differential Scanning Calorimetry (DSC) 
     TA INSTRUMENT® models Q2000, Q1000, or 2920 were used to generate DSC data. The measurement was made using standard TA Instruments open pans. The measurement was made at a heating rate of 10° C./min, in a nitrogen environment from room temperature to 300° C., with a sample size of about 2-10 mg. The DSC plot was made with the endothermic peaks pointing down. 
     Alternatively, about 5 mg of material was weighed into an aluminum DSC pan and sealed non-hermetically with a pierced aluminum lid. The sample pan was then loaded into a Seiko DSC6200 (equipped with a cooler), cooled, and held at 20° C. Once a stable heat-flow response was obtained, the sample and reference were heated to 260, 270, 285, 290, 295, 300, 310 or 330° C. at scan rate of 10° C./min and the resulting heat flow response monitored. Nitrogen was used as the purge gas, at a flow rate of 50 cm 3 /min. 
     Thermogravimetric Analysis (TGA) 
     TA INSTRUMENT® models Q5000, Q500, or 2950 were used to generate TGA data. The measurement was made using standard TA Instruments Platinum pans. The measurement was made at a heating rate of 10° C./min, in a nitrogen environment from room temperature to 300° C., with a sample size about 10-30 mg. 
     Dynamic Vapor Sorption (DVS) 
     About 20 mg of the crystalline form was transferred into a dynamic vapor sorption instrument from Surface Measurement Systems Ltd. (SMS). The weight change was recorded relative to the relative humidity (Target RH %) at 25° C. 
     Solid-State Nuclear Magnetic Resonance (SSNMR) 
     Carbon-13 cross polarization magic angle spinning (CPMAS) solid-state NMR experiments were conducted on a Bruker AV III instrument operating at a proton frequency of 400.13 MHz. Solid samples were spun at 13 KHz in a 4 mm ZrO 2  rotor. The contact time was 1.5 to 3 milliseconds and was ramped on the proton channel from 50 to 100% (A. E. Bennett et al,  J. Chem. Phys.,  1995, 103, 6951), (G. Metz, X. Wu and S. O. Smith, J.  Magn. Reson. A.,  1994, 110, 219-227). The relaxation delay was maintained at 5× 1 H T 1  of API (typically 30 seconds). Proton decoupling was applied using a TPPM sequence with a 2.8 microsecond pulse (90 KHz nominal band width). The spectral sweep width was 300 ppm centered at 100 ppm. 2972 data points were acquired (giving a digital resolution of 20 Hz) and zero filled to 8192 prior to apodization with 20 Hz line broadening. Typically 1024 to 4096 free induction decays were co-added. The spectra were referenced indirectly to TMS using 3-methylglutaric acid (D. Barich, E. Gorman, M. Zell, and E. Munson,  Solid State Nuc. Mag. Res.,  2006, 30, 125-129). Approximately 70 mg of sample was used for each experiment. The temperature was set to 280K.

     Differential Scanning Calorimetry 
     Crystalline Forms A, B, C, D, F, and J were analyzed by differential scanning calorimetry (DSC) according to the conditions described in the General Procedures. Illustrative DSC thermograms for Forms A, B, C, D, F, and J are shown in  FIGS.  3 ,  5 C,  6 C,  7 C,  9 C, and  13 C , respectively. For instance, the crystalline Form A in  FIG.  3    showed an endothermic peak at about 261° C. In another example, the crystalline Form J in  FIG.  13 C  showed an onset of an endothermic peak at about 266° C. 
     Thermogravimetric Analysis 
     Crystalline Forms A and J were analyzed by thermogravimetric analysis (TGA) according to the conditions described in the General Procedures. Exemplary TGA thermograms for Forms A and J are shown in  FIGS.  4  and  13 D , respectively. For example, no significant loss of weight was observed for Form J in  FIG.  13 D  below about 250° C., with an onset of decomposition occurring at about 281° C. 
     Dynamic Vapor Sorption 
     Crystalline Forms A and J were analyzed by dynamic vapor sorption (DVS) according to the conditions described in the General Procedures. The DVS isotherms for Forms A and J are shown in  FIGS.  1 C,  1 D, and  13 E . For each of Form A and Form J, the DVS analysis indicated the crystalline form was not hygroscopic. Each of Form A and Form J did not change after being subjected to DVS conditions, with each form exhibiting substantially the same PXRD and IR post-DVS analysis. 
     Example 5: Characterization of the Crystalline Form a of Compound (I) by Solid-State Nuclear Magnetic Resonance (ssNMR) Spectroscopy 
     The  13 C solid-state CPMAS spectrum, as shown in  FIG.  2    for Form A was collected in accordance with the procedures described in General Procedure.
