Description

NOVEL FORMS OF AN INDAZOLO[5,4-A]PYRROLO [3,4-C] CARBAZOLE COMPOUND 5 FIELD OF THE INVENTION The present invention relates to compositions which contain the novel fused pyrrolocarbazole compound Compound I, pharmaceutical compositions comprising Compound I, processes to reproducibly make them and methods of treating patients using them. 10 BACKGROUND OF THE INVENTION Active pharmaceutical ingredients (APIs) can be prepared in a variety of different forms, for example, chemical derivatives, solvates, hydrates, co-crystals, or salts. APIs may also be amorphous, may have different crystalline polymorphs, or may exist in 15 different solvation or hydration states. By varying the form of an API, it is possible to vary the physical properties thereof For instance, crystalline polymorphs typically have different solubilities such that a more thermodynamically stable polymorph is less soluble than a less thermodynamically stable polymorph. Polymorphs can also differ in properties such as stability, bioavailability, morphology, vapor pressure, density, color, and 20 compressibility. Accordingly, variation of the crystalline state of an API is one of many ways in which to modulate the physical and pharmacological properties thereof. Various synthetic small organic molecules that are biologically active and generally known in the art as "fused pyrrolocarbazoles" have been prepared (See U.S. Pat. 25 Nos. 5,475,110; 5,591,855; 5,594,009; 5,616,724; and 6,630,500). In addition, U.S. Pat. No. 5,705,511 discloses fused pyrrolocarbazole compounds which possess a variety of functional pharmacological activities. The fused pyrrolocarbazoles were disclosed to be used in a variety of ways, including: enhancing the function and/or survival of cells of neuronal lineage, either singularly or in combination with neurotrophic factor(s) and/or 30 indolocarbazoles; enhancing trophic factor-induced activity; inhibition of protein kinase C ("PKC") activity; inhibition of trk tyrosine kinase activity; inhibition of proliferation of a 1 prostate cancer cell-line; inhibition of the cellular pathways involved in the inflammation process; and enhancement of the survival of neuronal cells at risk of dying. A specific fused pyrrolocarbazole compound, having the chemical designation 11 5 isobutyl-2-methyl-8-(2-pyrimidinylamino)-2,5,6,11,12,13-hexahydro-4H-indazolo[5,4 a]pyrrolo [3,4-c]carbazol-4-one is a potent, orally-active TIE-2/VEGF-R inhibitor having anti-tumor and anti-angiogenic activity, and is represented by the following formula (1): C N N 0 N /\ /N NN 1N (I) This Compound is referred to hereinafter as "Compound I". U.S. 7,169,802 describes Compound I and utility thereof. 15 Different chemical or solid state forms of Compound I can have different melting points, solubilities or rates of dissolution; these physical properties, either alone or in combination, can affect bioavailability. The physical properties of the various chemical/solid state forms of Compound I can also affect other aspects of drug development, such as manufacturing, processing, and storage characteristics. In light of 20 the potential benefits of alternative forms of APIs, a need exists to identify and prepare alternative forms of Compound I. SUMMARY OF THE INVENTION Various chemical forms of Compound I are described, as well as methods of their preparation. Pharmaceutical compositions comprising one or more of these chemical forms are also described, as are methods of treatment utilizing such compositions. 2 The pharmaceutical compositions of the present invention may be used in a variety of ways, including: for inhibition of angiogenesis; as antitumor agents; for enhancing the function and/or survival of cells of neuronal lineage, either singularly or in combination 5 with neurotrophic factor(s) and/or indolocarbazoles; for enhancing trophic factor-induced activity; inhibition of kinase activity, such as tik tyrosine kinase ("trk"), vascular endothelial growth factor receptor ("VEGFR") kinase, preferably VEGFR1 and VEGFR2, mixed lineage kinase ("MLK"), dual leucine zipper bearing kinase ("DLK"), platelet derived growth factor receptor kinase ("PDGFR"), protein kinase C ("PKC"), Tie-2, or 10 CDK-1, -2, -3, -4, -5, -6; for inhibition of NGF-stimulated trk phosphorylation; for inhibition of proliferation of a prostate cancer cell-line; for inhibition of the cellular pathways involved in the inflammation process; and for enhancement of the survival of neuronal cells at risk of dying. In addition, the pharmaceutical compositions may useful for inhibition of c-met, c-kit, and mutated Flt-3 containing internal tandem duplications in 15 the juxtamembrane domain. Because of these varied activities, the disclosed pharmaceutical compositions find utility in a variety of settings, including research and therapeutic environments. In other embodiments, the pharmaceutical compositions of the present invention 20 are useful for treating or preventing angiogenesis and angiogenic disorders such as cancer of solid tumors, endometriosis, retinopathy, diabetic retinopathy, psoriasis, hemangioblastoma, ocular disorders or macular degeneration.

The slurry was suction filtered using a 5ptm membrane filter and solid washed with methylene 15 chloride (2 x 1 OmL). The orange solution that resulted was concentrated to about 5 mL volume. During this time the solution became cloudy when 15-20 mL of volume remained. The slurry was chilled at 2-8'C overnight and vacuum filtered to give a yellow orange solid that was allowed to dry at room temperature to a constant weight of 230 mg (67% yield). 20 Preparation of Compound I -nTSA-A A 200.7 mg sample of Compound I free base (Cephalon France, Mitri Mory, France) (0.420 mmoles) was heated with stirring in 105 mL (523 vol.) of methylene chloride to the boiling point and held at this temperature with stirring for 2-3 minutes. The 25 cloudy, warm solution was filtered using a 5p syringe filter into a slurry of 165.7 mg pTSA acid monohydrate (0.871 mmoles) in 20 mL of methylene chloride with stirring. The initially clear orange solution dissolved all but a few visible particles of the pTSA acid. This solution was quickly syringe filtered with a 5R filter disk while maintaining the temperature. After filtration the solution turned cloudy and crystals were evident. The 30 solution was concentrated to about 25 mL by warming to the boiling point with stirring and chilled overnight at 2-8'C. The slurry was vacuum filtered and solid allowed to dry 45 about 4 hours in the hood at room temperature. The yellow-orange solid weighed 274.1 mg (79% yield). Preparation of Compound I pTSA-B 2 5 A 206.0 mg sample of Compound I free base (0.431 mmoles) was heated with stirring in 150 mL (728 vol.) of acetone to the boiling point and held at this temperature for 30 minutes to dissolve remaining fine particles. Additional acetone was added to make up for volume lost to evaporation. The orange-yellow solution was syringe filtered using a 10 5p syringe filter into a solution of 165.3 mg of pTSA monohydrate (0.869 mmoles) in 25 mL of acetone with stirring. In a short time after filtration a solid formed and remained while the slurry was concentrated to about 25 mL and chilled at 2-8'C overnight. The slurry was vacuum filtered and solid allowed to dry 21 hours in the oven at 50'C. The bright yellow-orange solid weighed 204.4 mg (58% yield). 5 Preparation of Compound I pTSA-C 2 20.6 mg of Compound I -Si (0.043mmoles) was dissolved at the boiling point in approximately 2.5 mL of n-propanol. This solution was syringe filtered while warm into a solution of 16.5 mg of p-toluenesulfonic acid monohydrate (0.086 mmoles) in 1 mL of n 20 propanol. An immediate color change in the solution was followed by formation of a precipitate. The mixture was concentrated to about 2 mL by heating to the boiling point and chilled overnight at 2-8'C. Suction filtration followed by air drying for 4 hours gave 22 mg (62% yield) of yellow solid. 25 Form Scale-Up Characterizations XRPD XRPD patterns were repeated at least twice to assure the reproducibility. The 30 numbers were assigned primarily based upon XRPD pattern, and as different powder patterns were found, the letters and numbers were incrementally assigned. The number I was assigned to identify mono pTSA salt forms such as pTSA-Ai, and 2 was used for the 46 di pTSA salt such as pTSA-A2 or pTSA-B2. The XRPD pattern for the single identified crystalline form of Compound I -pTSA 1:1 salt is shown in Figure 1 (pTSA-Ai), and the identified crystalline forms for the Compound I -PTSA 1:2 salt are shown in Figure 3 (pTSA-A2), Figure 5 (pTSA-B2) and Figure 7 (pTSA-C 2 ) 5 DSC and TGA The DSC curves for pTSA-Ai, pTSA-A2, pTSA-B2 and pTSA-C2 (Figure 2, Figure 4, Figure 6, and Figure 8, respectively) are distinguishing and can be used to identify the 10 particular solid-state phase (Table 32 below). Form pTSA-Ai shows a single peak at ca. 266.4'C with an enthalpy of fusion (AHfus) of 12.92 J/g. The DSC curve of form pTSA-A2 shows a peak at ca. 278.4'C with an enthalpy of fusion (AHfus) of 18.45 J/g. Form pTSA B2 exhibits an endotherm at a peak temperature of ca. 280.2*C with an enthalpy of fusion (AHfus) of 17.47 J/g. The existence of a desolvation process was discounted because no 15 weight loss was detected by TGA (Figure 2, Figure 4 and Figure 6). Form pTSA-C2 melts at a peak temperature of ca. 280.4'C with an enthalpy of fusion (Aibs H) of 77.13 J/g.

It is meant to be understood that peak heights (intensities) in a XRPD spectrum 5 may vary and will be dependent on variables such as the temperature, crystal size or morphology, sample preparation, or sample height in the analysis well of the PANalytical X Pert Pro diffractometer or Oxford Instruments Xcalibur3 diffractometer system. It is also meant to be understood that peak positions may vary when measured with 10 different radiation sources. For example, Cu-Kai, Mo-Ka, Co-Ka and Fe-Ka radiation, having wavelengths of 1.54060 A, 0.7107 A, 1.7902 A and 1.9373 A, respectively, may provide peak positions that differ from those measured with Cu-Ka radiation. The wavelength of Cu-Ka radiation is X = 1.54056 A. 15 It is further meant to be understood that the term "± 0.2 degrees 2-theta " following a series of peak positions means that all of the peaks of the group which it follows are reported in terms of angular positions with a variability of ± 0.2 degrees 2-theta. For example, "6.81, 8.52, 9.73, 12.04 and/or 13.25 ± 0.2 degrees 2-theta " means "6.81 + 0.2 degrees 2-theta, 8.52 ± 0.2 degrees 2-theta, 9.73 ± 0.2 degrees 2-theta, 12.04 ± 0.2 degrees 20 2-theta and/or 13.25 ± 0.2 degrees 2-theta". As those skilled in the art will appreciate, numerous modifications and variations of the present invention are possible in view of the above teachings. It is therefore understood that within the scope of the appended claims, the invention can be practiced otherwise than 25 as specifically described herein, and the scope of the invention is intended to encompass all such variations.
