Description

Attorney Docket No. 2019199-016218WOAMORPHOUS AND CRYSTALLINE FORMS OF 4-FLUORO-N-METHYL-N-(l-(4-(l-METHYL-lH- PYRAZOL-5-YL)PHTHALAZIN-l-YL)PIPERIDIN-4-YL)-2-(TRIFLUOROMETHYL)BENZAMIDE, AND USES THEREOFFIELD OF THE INVENTION

[0001] Described herein are amorphous and crystalline forms of 4-fluoro-N-methyl-N-(l-(4-(l-methyl-lH-pyrazol-5-yl)phthalazin-l-yl)piperidin-4-yl)-2-(trifluoromethyl)benzamide, which is a known hedgehog pathway inhibitor. Pharmaceutical compositions comprising the amorphous and / or crystalline forms, and the uses of such solid forms and compositions for the treatment of fibrosis, particularly pulmonary fibrosis, are also described.BACKGROUND OF THE INVENTION

[0002] Interstitial lung diseases (ILDs) are a group of over 200 fibrotic disorders that cause scarring in the lungs, damaging tissues in or around the lungs' alveoli.

[0003] Idiopathic pulmonary fibrosis (IPF) and non-IPF progressive pulmonary fibrosis (PPF) are ILDs with a terminal prognosis. In the United States, the prevalence of IPF is about 150,000, with an estimated 20,000 to 40,000 individuals diagnosed annually, while the prevalence of PPF is about 186,000, with ~84,000 individuals diagnosed annually. The current standards of care (pirfenidone, nintedanib) modestly slow the decline of lung function, but do not stop or reverse it; as such IPF prognosis remains poor, with respiratory failure typically occurring within 3-7 years of diagnosis. Furthermore, pirfenidone and nintedanib have tolerability issues that limit their long-term use in most patients.

[0004] The driver of IPF is dysregulated tissue remodeling. IPF is a chronic wound undergoing the wound healing process that has become excessive and unrelenting. Wound healing processes are driven by fibroblast activation and trans differentiation of cells into myofibroblasts which deposit fibrotic extracellular matrix. The dominant pathway that governs fibroblast activation and myofibroblast accumulation is the Hedgehog (Hh) pathway through activation of Smoothened (Smo).Page 1 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0005] 4-Fluoro-N-methyl-N-(l-(4-(l-methyl-lH-pyrazol-5-yl)phthalazin-l-yl)piperidin-4-yl)-2-(trifluoromethyl)benzamide (CAS No. 1258861-20-9), also known as TALADEGIB (or LY2940680 or ENV-101), is a potent, small-molecule inhibitor of the Hedgehog (Hh) signaling pathway that causes apoptosis of myofibroblasts, thereby eliminating the driver of pulmonary fibrotic pathology.

[0006] In a recent Phase 2a study, patients with mild to moderate IPF receiving TALADEGIB experienced statistically significant improvements in lung function and lung capacity, and reversal of lung fibrosis. TALADEGIB is currently under investigation in a phase 2b trial (the WHISTLE-PF trial, see ClinicalTrials.gov ID NCT06422884), in IPF patients, evaluating a range of TALADEGIB doses, and further assessing the effects on lung capacity and lung fibrosis and the effect on patient reported outcomes.SUMMARY OF THE INVENTION

[0007] In some embodiments, the present disclosure provides the recognition that there is a need for alternate forms of TALADEGIB that present advantageous properties, such as, but not limited to solubility, bioavailability, purity, stability, shelf life and the like. Accordingly, described herein are various forms of TALADEGIB (e.g. amorphous or crystalline), compositions comprising these forms, and methods of using the forms and compositions for treating fibrotic diseases, particularly pulmonary fibrosis.

[0079] The terms "effective amount", "therapeutically effective amount" or "pharmaceutically effective amount" as used herein, refer to an amount of at least one agent or compound being administered that is sufficient to treat or prevent the particular disease or condition. The result is the reduction and / or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an "effective amount" for therapeutic uses is the amount of the composition comprising a compound as disclosed herein required to provide a clinically significant decrease in a disease. An appropriate "effective" amount in any individual case is determined using techniques such as a dose escalation study.

[0080] The terms "substantially the same as" or "substantially similar to" as used herein, refers to a powder x-ray diffraction pattern or differential scanning calorimetry pattern that is nonidentical to those depicted herein, but that falls within the limits of experimental error, when considered by one of ordinary skill in the art.Modulating Hedgehog Pathway Activity

[0081] The Hedgehog (Hh) signaling pathway plays an important role in tissue regeneration and repair. The pathway is initiated by binding the extracellular Hh ligand Sonic Hedgehog (SHH) to the transmembrane receptor Patched (PTCH). In the absence of the ligand, PTCH inhibits the activity of the G-protein-coupled receptor-like protein Smoothened (SMO). When an SHH ligand binds to PTCH, it relieves the inhibition of SMO, allowing SMO to trigger a cascade of intracellular signaling events, ultimately activating the glioma-associated oncogene homolog (GLI) family of transcription factors.

[0082] Hh pathway components are typically present at low levels in healthy adult lung tissue. Following injury, Hh signaling increases, suggesting the pathway is initially suppressed and then reactivated to support cellular regeneration. Fibroblasts transition into myofibroblasts in response to tissue trauma, initiating tissue repair, and Hh signaling is essential for this process. After normal injury repair these cells are eliminated through apoptosis or deactivated.However, during fibrosis myofibroblasts persist, secreting growth factors and cytokines that drive disease progression, with SHH signaling implicated in aberrant myofibroblast differentiation and proliferation.Page 27 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0083] In IPF lungs, the Hh pathway is dysregulated, with pathway components SHH, PTCHI, SMO, GLI1, and GLI2 upregulated as compared with normal lungs. IPF is characterized by increased SHH expression, leading to sustained activation of Hh signaling by SHH. Inhibiting the Hh pathway greatly decreases myofibroblast differentiation and ECM protein levels. These findings highlight aberrant Hh signaling as a critical factor in the pathophysiology of IPF.

The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according toPage 33 of 9113250080vlAttorney Docket No. 2019199-016218WOestablished protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician.

[0115] The compounds, solid forms and compositions described herein, and where appropriate other therapeutic agent may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) sequentially or separately, depending upon the nature of the disease, the condition of the patient, and the actual choice of other therapeutic agent to be administered. For combinational applications and uses, the compounds, solid forms and compositions described herein and the therapeutic agent need not be administered simultaneously or essentially simultaneously. Thus, the compounds, solid forms and compositions as described herein may be administered first followed by the administration of the therapeutic agent; or the therapeutic agent may be administered first followed by the administration of the compounds, solid forms and compositions as described herein. This alternate administration may be repeated during a single treatment protocol. The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient. For example, the therapeutic agent may be administered first, and then the treatment continued with the administration of the compounds, solid forms and compositions as described herein followed, where determined advantageous, by the administration of the therapeutic agent, and so on until the treatment protocol is complete. Thus, in accordance with experience and knowledge, the practicing physician can modify each administration protocol for treatment according to the individual patient's needs, as the treatment proceeds. The attending clinician, in judging whether treatment is effective at the dosage administered, will consider the general well-being of the patient as well as more definite signs such as relief of disease-related symptoms. Relief of disease-related symptoms such as pain, and improvement in overall condition can also be used to help judge effectiveness of treatment.

[0128] The examples and preparations provided below further illustrate and exemplify the compounds of the present invention and methods of preparing such compounds. It is to be understood that the scope of the present invention is not limited in any way by the scope of the following examples and preparations.INTRODUCTION

[0129] TALADEGIB was prepared according to previously described methods, see for example, US patent 8,273,742, Column 11, Example 11. In brief, N-methyl-l-(4-lmethyl-lH-pyrazol-5-yl)phthalazine-l-yl)piperidin-4-amine and 4-fluoro-2-(trifluoromethyl) benzoly chloride were coupled in the presence of base. Purification of the resulting product by flash silica gelPage 41 of 9113250080vlAttorney Docket No. 2019199-016218WOchromatography (hexane / ethyl acetate / 2M NH3 in MeOH 20 / 5 / 1) provides the free base as a yellow foam.

[0130] Amorphous TALADEGIB was prepared by rapid evaporation, under vacuum, of a methanol solution.

[0131] A first, non-solvated, crystalline form, designated FORM I, was readily identified by crystallization from ethanol and water.

[0132] Described herein are studies to:- characterize TALADEGIB crystalline FORM I;- comprehensively screen for and subsequently characterize solid-state forms of TALADEGIB; - understand TALADEGIB crystallization behavior.

[0133] A variety of crystallization techniques and conditions were employed to screen for TALADEGIB solid crystalline forms. While most conditions yielded FORM I (the thermodynamically most stable form), seven additional crystalline forms were identified and characterized: five solvates - toluene, anisole, benzyl alcohol (x2), and methyl t-butyl ether (MTBE), a variable hydrate and a new form characterized by XRPD pattern B. The following abbreviations may be used:Page 42 of 9113250080vlAttorney Docket No. 2019199-016218WOCHARACTERIZATION OF FORM I EXAMPLE 1: FORM I X-RAY POWDER DIFFRACTION (XRPD)

[0134] X-ray powder diffraction (XRPD) patterns were collected on a Bruker D8 Advance X-ray powder diffractometer, equipped with a CuKa source (X=l.54056 A) and a Linxeye detector, and operating at 40 kV and 40 mA, with a 0.2 mm divergence slit (samples were scanned from 4-30° in 0.02°2 steps at a rate of 0.2 seconds per step). Experimental data was processed using DiffracPIus EVA software (Version 14.0).

[0135] X-ray capillary analysis was performed using a Bruker D8 Advance diffractometer, equipped with a General Area Diffraction Detection System (GADDS, v. 4.1.20). An incident beam of CuK radiation was produced using a fine-focus tube (40 kV, 40 mA), cross-coupled powder Gobel mirrors and a 0.5 mm double pinhole collimator. Samples were packed into standard (special) glass thin-walled capillary tubes (Charles Supper Co.) and sealed using vinyl plastic putty (Critoseal®, McCormick Scientific) prior to mounting on the goniometer. A video camera and laser were used to position the area of interest to intersect the incident beam in transmission geometry. Diffraction patterns were collected using a Hi-Star area detector located at 20 or 30 cm from the sample and processed using GADDS. The signal intensity in the GADDS image was integrated using a step size of 0.04° 20 to produce a diffraction pattern as a function of 29. Experimental data were processed using DiffracPIus EVA software (Version 14.0).

[0138] Table 2 shows the FORM I XRPD peak list, sorted by relative intensity.Table 2: FORM I XRPD Peak List (sorted by relative intensity)Page 43 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 2: FORM I OPTICAL PHOTOMICROGRAPH

[0139] An optical photomicrograph of FORM I was collected using an Olympus BX51TF polarizing light microscope, equipped with Olympus 10X, 20X and 50X LMPIan Fl objectives, a 100X oil immersion objective, a PaxCAM2 digital camera, and interfaced with a PC. Samples were imaged in their mother liquors or in the dry state between glass slides. In some instances, oil (Non-drying Immersion Oil for Microscopy Type A, Cargille Laboratories, Inc.) was used. Images were processed using PAX-it software (Versions 6.3 or 7.4). FIGURE 3 shows the FORM I Optical Photomicrograph.EXAMPLE 3: SINGLE CRYSTAL X-RAY of FORM IPage 44 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0140] Single crystal X-ray diffraction data were collected using a Bruker-Nonius Kappa geometry diffractometer equipped with either a CuKa(X = 1.54178A) or MoKa(X = 0.71073A) radiation source and a SMART 6000CCD area detector. Cell refinement and data reduction were accomplished using the SAINT software program (SAINT version 6.2, Bruker AXS Inc.). Structures were solved by direct methods using Siemens SHELXTL-PLUS (Sheldrick, G.M. SHELXTL V5.1). Non-hydrogen atoms were refined anisotropically. All other hydrogen atoms, which were included in the structure factor calculations, were placed in idealized positions (dc-H = 0.95A) and independently refined. The single crystal X-ray structure of FORM I was solved at 100K and room temperature.

[0141] FORM I crystallizes in the centrosymmetric monoclinic space group, P2- c, with one molecule in the crystallographic asymmetric unit (Z' = 1).

[0142] FIGURE 4 shows ORTEP diagrams of the molecule identified in the asymmetric unit, at (a) RT; (b) 100 K; and (c) superimposed crystallographic asymmetric units at both temperatures.

[0144] Differential scanning calorimetry (DSC) was conducted using a TA Q1000 DSC. Samples were equilibrated at 25°C in hermetically-sealed aluminum pans, then heated to ~200°C at 2, 5, 20 or 50 °C / min with a nitrogen purge (50mL / min). The temperature and heat flow were calibrated against indium melting.

[0145] FIGURE 6 shows the TALADEGIB FORM I DSC trace measured at 20°C / min. A single endothermic transition was observed at 189.0°C, corresponding to the melting point.The heat of fusion was ~100 J / g.

[0146] FIGURE 7 shows TALADEGIB FORM I DSC traces measured at 50°C / min (upper trace), 10°C / min (middle trace) and 2°C / min (lower trace). Single endothermic transitions were observed at 189.6°C, 188.7°Cand 188.0°C, respectively, corresponding to the melting point.

[0147] The heat of fusion was ~100 J / g.EXAMPLE 5: FORM I NMRPage 46 of 9113250080vlAttorney Docket No. 2019199-016218WOSolution-state1H NMR

[0148] Solution-state1H NMR spectra were collected on a 400 MHz Varian Unity INOVA spectrometer operating at1H and13C frequencies of 399.770 and 100.531 MHz, respectively, using a 5 mm Varian 400ATB PFG probe.FIGURE 8 shows theXH-NMR spectrum of TALADEGIB FORM I, collected in DMSO-d6at 25°C.Solid-state13C NMR

[0149] Cross polarization / magic angle spinning (CP / MAS) NMR (solid-state NMR) spectra were obtained on a Bruker Avance III 400 wide-bore NMR spectrometer operating at1H and13C frequencies of 400.131 and 100.623 MHz, respectively, and using a Bruker 4 mm triple resonance probe.13C chemical shifts were externally referenced (± 0.05 ppm) to the proton-decoupled13C peak of SiMe4 via the high-field resonance of adamantane (8 = 29.5 ppm).FIGURE 9 shows the solid-state13C NMR spectrum of TALADEGIB FORM I, collected at 297K. Solid-state19F Magic Angle Spinning NMR

[0150] 19F Magic angle spinning (MAS) NMR spectra were obtained using a Bruker Avance II 400 MHz NMR spectrometer operating at a fluorine frequency of 376.459 MHz and equipped with a Bruker 4 mm triple resonance probe.3H decoupling was employed using TPPM15 (55.0 Watts). Chemical shifts were externally referenced to polytetrafluoroethylene (6 = -122.7 ppm).FIGURE 10 shows the solid-state19F NMR spectra of TALADEGIB FORM I, collected at 25 °C, and measured at magic angle spinning (MAS) speeds of 15 kHz (upper trace) and 12 kHz (lower trace). It should be noted, peaks that shift as a function of the sample spin rate are designated as spinning side bands, while peaks that do not shift are the isotropic19F resonances (denoted by arrows in the figure). Predicted and observed19F chemical shifts were as follows:Predicted ObservedC-F -61 ppm -60.2 ppmCF3 -110 ppm 3 peaks between -100 and -120 ppmEXAMPLE 6: DIFFERENTIAL THERMAL (DT) / TH ERMOGRAVI METRIC (TG) ANALYSES

[0151] Differential thermal / thermogravimetric analyses were carried out on a TA simultaneous DSC-TGA model Q600. Samples were heated in aluminum pans from ambient temperature to 160-300 °C at a 10 °C / min heating rate with a nitrogen purge (lOOmL / min). The temperaturePage 47 of 9113250080vlAttorney Docket No. 2019199-016218WOwas calibrated with Indium. Weight calibration was performed with manufacturer supplied standards and verified against sodium tartrate dihydrate desolvation.

[0152] FIGURE 11 shows the TALADEGIB FORM I TG-DTA thermogram which presents a single endothermic event at ~188°C, corresponding to the melting point. TGA showed the total volatile content was negligible, confirming the material to be non-solvated.EXAMPLE 7: FORM I MOISTURE SORPTION ANALYSIS

[0153] Moisture sorption analysis was performed at 25°C using a VTI flow moisture balance (Model SGA-100 or Model CX). The following experimental conditions were used: sample size ~20 mg, 5-95% RH adsorption / desorption range, 5% RH step interval. The minimum equilibration criterion was <0.01% weight gain in 15 minutes for a maximum time of 120 minutes.

[0154] FIGURE 12 shows the TALADEGIB FORM I moisture sorption isotherm. A small weight gain was observed by moisture sorption up to 55% RH, followed by a sudden decrease in weight from 55-70% RH.EXAMPLE 8: AMORPHOUS FORM XRPD

[0155] The XRPD of amorphous material was obtained according to the procedures described above. The pattern, showing no sharp peaks, is shown in FIGURE 13.EXAMPLE 9: CONVERSION of FORM I to AMORPHOUS

[0156] FORM I was dissolved in either methanol or THF at room temperature, syringe filtered (0.25 pm filter) into a round bottom flask and the solvent was then rapidly evaporated to dryness under vacuum. The resultant material was analyzed by XRPD and the results presented in Table 4, which shows that fast evaporation of methanol on a small scale yields amorphous material; however, a slightly larger scale yields a mixture of FORM I and amorphous material. Fast evaporation of THF (in which TALADEGIB has higher solubility) yields the amorphous form with trace amounts of FORM I.Table 4: Preparation of Amorphous TALADEGIBPage 48 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 10: CRYSTALLIZATION of the AMORPHOUS FORM

[0157] Amorphous TALADEGIB was seeded with crystalline solvate forms under varying humidity and temperature conditions. The results are presented in Table 5, and show that seeding at room temperature / high humidity or elevated temperature / lower humidity, results in crystallization of amorphous TALADEGIB to FORM I. In all other instances, crystallization was not observed and amorphous material was isolated.Table 5: Solvate Seeding of Amorphous FormSCREENING for NEW CRYSTALLINE FORMSSOLUTION BASED CRYSTALLIZATION

[0158] Solution based crystallization techniques were implemented to identify crystalline forms of TALADEGIB. Amorphous material was prepared by rotary evaporation from methanol or THF. Solvents were purchased from typical suppliers and used as received. Solvents used forPage 49 of 9113250080vlAttorney Docket No. 2019199-016218WOcrystallization screening were reagent grade (99+% purity). Solvents used for preparing mobile phases were HPLC grade. Solvent abbreviations include the following:Abbr NameEXAMPLE 11: SLURRY- SOLUBILITY SCREEN

[0159] Solubility (mg / mL) was measured at 25°C and / or 50°C, in solvents and aqueous-organic solvent mixtures. Suspensions were sampled after 2 and 24 hours and residue analysis performed. The results are presented in Table 6 and show that all conditions (with one exception - DMSO at 25°C), resulted in FORM I. Equilibration in DMSO at 25°C yielded amorphous material (A*) with two sharp diffraction peaks (~8.9 and 17.720), neither of which correspond to FORM I; at 50°C FORM I was isolated.Table 6: Slurry-Solubility Screen performed at 25°C (2hr & 24hr) and 50°C (24hr)Page 50 of 9113250080vlAttorney Docket No. 2019199-016218WO> > > >> > >EXAMPLE 12: LABILE SOLVATE SLURRY SCREEN

[0160] A screen for labile solvates (solvates that are stable only in suspensions) was performed.

[0161] Slurries of FORM I in various solvents / solvent systems (see Table 7) were prepared and allowed to stand at room temperature for ~ 11 days. The slurries were then filtered and the isolated solids, both from the wet cakes and after drying, were analyzed by XRPD. In all instances only FORM I was observed, indicating no solvate formation had occurred.Table 7: Labile Slurry ScreenPage 51 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 13: CRYSTALLIZATION FROM MTBE

[0162] Amorphous TALADEGIB was dissolved in MTBE and stirred at 60°C for 1 hour; during which time the MTBE solvate crystallized. The slurry was cooled to room temperature then stirred overnight. The solid product was filtered under vacuum and air dried to provide an MTBE solvate form.EXAMPLE 14: EVAPORATIVE CRYSTALLIZATION

[0163] An evaporative crystallization screen was performed, under slow (room temp and 5°C) and fast (50°C) evaporation conditions. TALADEGIB (~25mg) was dispensed into 24 (4 mL) vials and then solvents (0.1-4mL) were added. The resulting suspensions / solutions were filtered through 0.45 pm syringe filters into clean vials. The vials were covered with either parafilm or aluminum foil rendered with a pinhole or loosely capped, then placed in a fume hood or refrigerator, allowing the solvents to slowly evaporate at room temperature or 5°C. Filtered solutions were also evaporated at 50°C uncovered. Residues were analyzed after evaporation to dryness. The results are presented in Table 8 and show that most (~70%) conditions resulted in formation of FORM I. Conditions designed to capture metastable, disordered forms (high temperature, fast evaporation) from the more volatile organic solvents yielded amorphous material.

[0164] One new XRPD pattern - a toluene solvate - crystallized concomitantly with FORM I from toluene-organic solvent mixtures. The toluene solvate crystallizes upon scraping the glassy material produced by solvent evaporation with a spatula, (rather than occurring spontaneously upon solvent evaporation). In some instances, (*) solids initially observed as a glass, crystallized on scraping with a spatula.Table 8: Evaporative CrystallizationPage 52 of 9113250080vlAttorney Docket No. 2019199-016218WOPage 53 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 15: COOLING CRYSTALLIZATION

[0165] A cooling crystallization screen was conducted from pure and mixed solvent systems, under linear or natural cooling conditions.

[0166] TALADEGIB (~0.8 mg) was dispensed into vials and solvents (0.5-1.6 mL) were added. The vials were transferred to an Avantium Crystall6 parallel crystallizer, equipped with heating / cooling, magnetic stirring and turbidity sensors. The suspensions were stirred at 700 or 1000 rpm and heated to 60°C at l°C / min, equilibrated for 15 minutes, then cooled to 5°C at 0.25°C / min. The heat / cool cycle was performed twice. Alternatively, TALADEGIB was weighedPage 54 of 9113250080vlAttorney Docket No. 2019199-016218WOinto round bottom flasks and solvents were added. The solutions were generally heated to ~5°C above the temperature at which dissolution was visually complete. The heat source was then removed and the solutions allowed to cooled naturally. Any resulting solids were isolated by vacuum filtration or decantation. When cooling failed to induce precipitation, the resulting solutions were stored in the refrigerator for ~12 days. If crystallization was not observed following low temperature storage, the solutions were warmed to room temperature and allowed to slowly evaporate. The results are presented in Table 9 and show that all conditions yielded FORM I exclusively. [Note, in some solvents, dissolution was incomplete (*)].Table 9: Cooling Crystallization ExperimentsPage 55 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 16: ANTISOLVENT ADDITION CRYSTALLIZATION

[0167] An antisolvent addition crystallization screen was performed.

[0168] TALADEGIB (40 ± 2 mg) was dispensed into 45 (4 mL) vials and solvents (1-4 mL) were added. For standard antisolvent addition experiments (AA), antisolvent was added dropwise until either persistent clouding was observed or the maximum volume of the vial was reached. Reverse antisolvent addition experiments (RAA) involved filtering the solutions into vials containing antisolvent. Standard antisolvent addition experiments (AA) were conducted at room temperature only; reverse antisolvent addition experiments (RAA) were conducted at 5°C, ~25°C (room temperature) and 50°C. Solid products were isolated by vacuum filtration andPage 56 of 9113250080vlAttorney Docket No. 2019199-016218WOair-dried. The results are presented in Table 10, which shows that in all instances where solids were isolated, only FORM I was isolated.Table 10: Antisolvent Addition Crystallization Experiments>Page 57 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 17: VAPOR DIFFUSION CRYSTALLIZATION

[0169] A vapor diffusion screen was performed.

[0170] Antisolvents vapors were diffused into either solutions (method LL: liquid-liquid diffusion), or onto solid amorphous material (method LS: liquid-solid diffusion), to induce crystallization.

[0171] Amorphous TALADEGIB (~20 mg) was dispensed into 4 mL vials, solvents (0.2-4 mL) added and the resulting solutions stirred and filtered to remove any undissolved particulates. Antisolvent (1-2 mL) was added to a 20 mL jar. The open vial was placed in the jar which was then capped. Liquid-solid vapor diffusion experiments were performed by diffusing solvent vapors onto freshly prepared solid amorphous TALADEGIB. All experiments were conducted at room temperature. The solid products were recovered by either decantation of the mother liquor or vacuum filtration, then air-dried. The results are presented in Table 11, which shows that in all instances only FORM I was isolated.Table 11: Vapor Diffusion CrystallizationPage 58 of 9113250080vlAttorney Docket No. 2019199-016218WOEXAMPLE 18: CRYSTALLIZATION FROM HIGHLY SUPERSATURATED SOLUTIONS

[0176] Crystallization from slurries of amorphous material under a range of conditions, was studied. The results are presented in Table 15, and show that with one exception (*), all of the slurry experiments yielded FORM I. Slurrying in water at 90°C for 2 hours produced FORM I, along with two additional sharp diffraction peaks (~7.8 and 19.7°20). On cooling to room temperature, the two new peaks disappeared and the isolated solid was pure FORM I.Table 15: Slurry Annealing<<<EXAMPLE 23: WET GRINDING of FORM I

[0177] Crystallization from wet grinding of crystalline FORM I, at room temperature, was studied.

Two stainless steel balls and ~4-5 drops of solvent were added and the jar closed with a stainless steel cap. The jar was shaken in 5 or 10 minute increments for 5-30 minutes, at a power setting of 30 Hz. Alternatively, a few drops of solvent were added to solid material and the wetted solids were gently ground using a pestle and mortar (P&M). Recovered solids were air dried at room temperature. The results are presented in Table 16, and show that grinding of FORM I yielded only FORM I.

[0219] Slurrying conditions generated new crystalline material isolated from six acids, (described in greater detail below, examples 37 - 42):Benzenesulfonic acid (Besylic acid, BSA)Ethane-l,2-disulfonic acid (Edisylic acid, EDSA)Hydrochloric acid (HCI)Naphthalene-l,5-disulfonic acid (Napadisylate, NDSA)Naphthalene-2-sulfonic acid (Napsylate, NSA)Toluenesulfonic acid (Tosylic acid, TSA)EXAMPLE 37: TALADEGIB BesylatePage 82 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0220] A solution of benzenesulfonic acid (11.3 mg, 1 eq) in ethanol (0.5mL) was added to TALADEGIB (34.3 mg), to afford a clear solution. The solution was placed in a refrigerator and stirred at sub-ambient temperature for approximately 5 days, during which time solids formed. The resulting suspension was centrifuged, the mother liquor removed by decanting, and the remaining solids isolated and analyzed.

[0221] XRPD shows the material is crystalline and is likely hydrated.

[0222] 1HNMR is consistent with the chemical structures of TALADEGIB and benzenesulfonic acid in a 1:1 stoichiometry. TALADEGIB peak shifts, from 2.8 & 3.3 ppm to 3.3 & 3.5 respectively, are indicative of salt formation. The peaks around 4 ppm are also slightly shifted downfield. Trace solvent contaminants (0.1 moles diethyl ether) were observed,The TG thermogram shows overlapping weight losses from ambient to 80°C (2.9%) and from 80°C to 132°C (1.0%), consistent with a hydrated material.

[0223] The total loss is likely due to water, equivalent to about 1.5 mole water per mole of the 1:1 salt.

[0224] The DSC thermogram shows a broad endotherm at 77°C, concurrent with the weight loss, and is likely a dehydration event. This is followed by two additional endotherms at 150°C (likely a solid-state transition upon heating) and 171°C likely due to melting.

[0226] Concentrated hydrochloric acid (7.6 pL, 1 eq) was added to a suspension of TALADEGIB (45.1 mg,) in methyl tert-butyl ether (ImL). The resultant mixture was stirred at ambient temperature for approximately 5 days. It was then centrifuged, the mother liquor removed by decanting, and the remaining solids isolated and analyzed.

[0227] By XRPD, the material is crystalline containing trace TALADEGIB Form I.

[0228] 1HNMR is consistent with the chemical structure of TALADEGIB, and the same peak shifts as observed for the Besylate salt were present.

[0229] The TG thermogram shows a very small (0.2%) weight loss starting at 139°C, equivalent to a negligible amount of water or MTBE, consistent with anhydrous material.

[0230] The DSC thermogram shows an endotherm at 215°C likely due to melting, with a shoulder present at 186°C possibly due to the melt of TALADEGIB Form I.

[0232] A solution of ethane-l,2-disulfonic acid dihydrate (21.7 mg, 1 eq) in / so-propanol (0.5mL) was added to TALADEGIB (46.9 mg). Additional solvent (0.5 mL) was added, and the resulting suspension heated for two hours at approximately 50°C, resulting in complete dissolution. The solution was cooled to ambient temperature and then placed in a refrigerator and stirred at sub-ambient temperature for approximately 5 days, during which time solids formed. The resulting suspension was centrifuged, the mother liquor removed by decanting, and the remaining solids isolated and analyzed.

[0233] Edisylate 1 is likely a mixed IPA solvate / hydrate.

[0234] XRPD shows the material to be crystalline with a significant amorphous component.Page 84 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0235] 1HNMR is consistent with the chemical structures of TALADEGIB and ethane-1,2-disulfonic acid and shows the presence of 0.9 moles / so-propanol. The TALADEGIB : acid stoichiometry is 3:2 or possibly 2:1 with a slight excess of acid.

[0236] The TG thermogram shows significant weight loss (9.1%) from ambient through 149°C.

[0237] The DSC thermogram does not show a clear melt event, though the minor endotherm at 148°C, is likely due to melting. The broad endotherm at 115°C is concurrent with the weight loss observed in the TG thermogram, likely due to dehydration / desolvation.

[0238] Figure 40 shows the XRPD (top),1HNMR spectrum (middle) and thermograms (bottom) of the TALADEGIB Edisylate salt.EXAMPLE 40: TALADEGIB Napadisylate

[0239] A solution of naphthalene-l,5-disulfonic acid tetrahydrate (31.5 mg, 1 eq) in ethanol (0.5mL) was added to TALADEGIB (43.1 mg), to produce a clear solution. The solution was placed in a refrigerator and stirred at sub-ambient temperature for approximately 5 days, during which time solids formed. The resulting suspension was then centrifuged, the mother liquor removed by decanting, and the remaining solids isolated and analyzed.

[0240] The obtained TALADEGIB napadysilate salt is likely hydrated.

[0241] XRPD shows the material to be crystalline, with some disorder and amorphous content.

[0242] 1HNMR is consistent with the chemical structures of TALADEGIB and naphthalene-1,5-disulfonic acid in a 2:1 stoichiometry. Trace amounts (0.05 moles) of ethanol were present. Similar peak shifts as seen for other salts were observed.

[0243] The TG thermogram shows a 1.3% weight loss, mostly occurring below 100°C, attributed to water loss, equivalent to one mole of water per mole of salt.Page 85 of 9113250080vlAttorney Docket No. 2019199-016218WO

[0244] The DSC thermogram does not show a clear melt endotherm. The endotherm at 78°C is due to dehydration / desolvation as it is broad and occurs concurrently with the weight loss in the TG thermogram.

[0245] Figure 41 shows the XRPD (top),1HNMR spectrum (middle) and thermograms (bottom) of the TALADEGIB Napadisylate salt.EXAMPLE 41: TALADEGIB Napsylate>

[0246] A solution of naphthalene-2-sulfonic acid monohydrate (24.4 mg, 1 eq) in / so-propanol (0.5mL) was added to TALADEGIB (46.7 mg). Additional solvent (0.5 mL) was added, and the suspension was heated at 50°Cfortwo hours, resulting in complete dissolution. The solution was cooled to ambient temperature and then placed in a refrigerator and stirred at subambient temperature for approximately 5 days, during which time solids formed.

[0251] A solution of toluenesulfonic acid (20.9 mg, 1 eq) in acetone (0.5mL) was added to TALADEGIB (38.4mg,), resulting in the formation of a thick solid plug. Additional solvent was added, and the thick suspension stirred at ambient temperature for approximately 5 days. The suspension was centrifuged, the mother liquor removed by decanting, and the remaining solids isolated.

[0252] XRPD shows the material to be crystalline, with some disordered and amorphous material.

[0253] 1HNMR is consistent with the chemical structures of TALADEGIB and toluenesulfonic acid in a 1:1 stoichiometry. A small amount (0.2 moles) of acetone was observed. Similar peak shifts as seen for other salts were observed.
