[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of and priority to International Patent Application No. PCT / CN2021 / 125016, filed October 20, 2021, the contents of which are incorporated herein by reference in their entirety.
[0002] FIELD OF THE INVENTION This application relates to crystalline forms of (R)—N-(4-([1,2,4]triazolo[1,5-c]pyrimidin-7-yloxy)-3-methylphenyl)-5-((3,3-difluoro-1-methylpiperidin-4-yl)oxy)-6-methoxyquinazolin-4-amine, processes for their preparation, pharmaceutical compositions containing one or more crystalline forms as active ingredients, and uses of the crystalline forms in the treatment of hyperproliferative diseases. [Background technology]
[0003] Background of the Invention The type I tyrosine kinase receptor family consists of four structurally related receptors: EGFR (ErbB1 or HER1), ErbB2 (HER2), ErbB3 (HER3), and ErbB4 (HER4) (reviewed in Riese and Stern, Bioessays, 1998, 20:41-48; Olayioye et al., EMBO Journal, 2000, 19:3159-3167; and Schlessinger, Cell, 2002, 110:669-672). All four family members have nearly identical structures, consisting of an extracellular region or ectodomain or ligand-binding region, a single transmembrane region, and an intracellular cytoplasmic tyrosine kinase domain.
[0004] It has been demonstrated that ErbB2 plays a role in cancer development. ErbB2 overexpression occurs in 20-25% of breast cancer (BC) patients (Leyland-Jones B, J Clin Oncol., 2009, 5278-86). Approximately 1,700,000 new cases of BC are diagnosed each year (Cardoso F, et al., Breast, 2018, 131-138), and 80% of BC are invasive, requiring chemotherapy, radiation, or targeted therapy in addition to surgery (Dai X., et al., Am J Cancer Res., 2015, 2929-2943). Brain metastases frequently occur in patients with metastatic breast cancer. The overall survival of patients with breast cancer brain metastases (BCBM) ranges from 2 to 25.3 months (Leone JP Exp. Hematol. Oncol., 2015, 4, 33). Surgery, whole-brain radiation therapy (WBRT), and stereotactic radiosurgery (SRS) are the three main treatment options for BCBM. Surgery is used for solitary metastases or up to three brain metastases. SRS may be used for patients with four or fewer intracranial lesions. WBRT is used to manage multiple brain metastases but can result in significant neurocognitive decline (Venur VA et al., Int. J. Mol. Sci., 2016, 1543).
[0005] Compared with other types of breast cancer, ErbB2-positive tumors have a higher incidence of brain metastases, with up to 50% of patients with ErbB2-positive breast cancer developing intracranial metastases (Leyland-Jones B, J Clin Oncol., 2009, 5278-86). The high prevalence of BCBM in ErbB2-positive patients is thought to be due to the inherent tropism of ErbB2-positive breast cancer cells to the brain, the prolonged survival of patients treated with anti-ErbB2 therapy, and the limited intracranial activity of anti-ErbB2 therapy (Venur V.A. et al., Int. J. Mol. Sci., 2016, 17, 1543).
[0006] Several anti-ErbB2 agents have been developed for clinical use, including monoclonal antibodies such as trastuzumab, antibody-drug conjugates (ADCs) such as T-DM1, and tyrosine kinase inhibitors (TKIs) such as lapatinib, neratinib, afatinib, and tucatinib (Kabraji S. et al., Clinical Cancer Research, 2018, 3351; Askoxylakis V. et al., JNCI J Natl Cancer Inst, 2015, 763-763; Tanaka Y. et al., Scientific Reports, 2018, 343; Zhang, Shilong, et al., Acta Pharmacologica Sinica, 2017, 233-240; Dinkel V. et al., Cancer Research, 2012, 72). However, none of these antibodies, ADCs, or TKIs are considered to be central nervous system (CNS) permeable. Limited clinical efficacy has been observed when treating patients with BCBM with the non-brain-penetrating aforementioned antibodies, ADCs, and TKIs.
[0007] WO 2020 / 057511, the entirety of which is incorporated herein by reference, discloses quinazoline compounds that inhibit type I receptor tyrosine kinase, exhibit good brain penetrance in animals, and have a favorable toxicity profile (e.g., reduced activity against hERG), and are therefore particularly useful for the treatment of type I receptor tyrosine kinase-mediated diseases or conditions, particularly ErbB2-related diseases or conditions, including cancer (e.g., metastatic cancer, such as brain metastasis). A particular compound (also referred to herein as Compound (I)) identified as (R)—N-(4-([1,2,4]triazolo[1,5-c]pyrimidin-7-yloxy)-3-methylphenyl)-5-((3,3-difluoro-1-methylpiperidin-4-yl)oxy)-6-methoxyquinazolin-4-amine TIFF2026027273000001.tif33170 is considered an efficient blood-brain barrier (BBB)-permeable ErbB2 (HER2) inhibitor that exhibits high selectivity over wild-type EGFR to minimize EGFR-mediated diarrhea and skin rash, and is therefore useful for treating ErbB2-positive BC patients with or without brain metastases (see Example 31 and biochemical assays in WO 2020 / 057511).
[0008] Polymorphism is the existence of different crystalline forms of a single compound and is a characteristic of some compounds and complexes. Thus, polymorphs are distinct solids that share the same molecular formula, but each polymorph may have distinct solid-state physical properties. A single compound can therefore produce various polymorphs, each with distinct solid-state physical properties such as a different solubility profile, melting point temperature, flowability, dissolution rate, and / or different X-ray diffraction peaks. These actual physical properties are influenced by the conformation and orientation of molecules within the unit cell that defines a particular polymorph of a substance. Due to the potential for variable solubility of each polymorph, identifying the existence of pharmaceutical polymorphs is essential to providing pharmaceuticals with predictable solubility profiles. It is desirable to investigate all solid forms of a drug, including all polymorphic forms, and determine the stability, dissolution, and flow properties of each polymorphic form. Polymorphic forms of a compound can be distinguished in the laboratory by X-ray diffraction spectroscopy, such as X-ray powder diffraction (XRPD), and other methods, such as infrared spectroscopy. Furthermore, polymorphic forms of the same drug substance or active pharmaceutical ingredient, which may be administered alone or formulated as a pharmaceutical composition, are well known in the pharmaceutical arts to affect, for example, the solubility, stability, flowability, handling, and compressibility of the drug substance, as well as the safety and efficacy of the formulation. For further details, see Hilfiker, Rolf (ed.), Polymorphism in the Pharmaceutical Industry, Weinheim, Germany: Wiley-VCH 2006.
[0009] The discovery of new polymorphs of pharmaceutically useful compounds provides new opportunities for improving the performance characteristics of pharmaceutical products. Therefore, there is a continuing need to investigate the polymorphic forms of the quinazoline compounds that exhibit type I receptor tyrosine kinase inhibitory activity. It has now been discovered that new polymorphs of compound (I) exist. Summary of the Invention

[0021] Detailed Description of the Invention Reference will now be made in detail to certain embodiments, examples of which are set forth in the accompanying detailed description. While enumerated embodiments are described, it will be understood that they are not intended to limit the invention to those embodiments. On the contrary, the present invention is intended to cover all alternatives, modifications, and equivalents, which may be included within the scope of the present invention as defined by the claims. Those skilled in the art will recognize many methods and materials similar or equivalent to those described herein, which could be used in the practice of the present invention. The present invention is in no way limited to the methods and materials described. In the event that one or more of the incorporated literature and similar materials differs or contradicts with this application, including, but not limited to, defined terms, term usage, described techniques, etc., this application controls.
[0022] It will be appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
[0023] definition Terms used in this specification have their ordinary meaning, and the meaning of such terms is independent at each occurrence. Nevertheless, unless otherwise stated, the following definitions apply throughout the specification and claims.
[0024] As used herein, the terms "comprise," "comprising," "include," and "including" are intended to specify the presence of stated features, integers, components, or steps, but do not exclude the presence or addition of one or more other features, integers, components, steps, or groups thereof.
[0025] As used herein, the term "about" means approximately, in the region of, roughly, or around. When the term "about" is used in conjunction with a numerical range, it modifies that range by expanding the upper and lower limits of the stated numerical values. Generally, the term "about" is used herein to modify numerical values above and below a given value by a variance of 20%, typically 10%, more typically 5%, even more typically 1%, and even more typically 0.1%. Sometimes, such ranges may be within the range of experimental error, the type of standard method used to measure and / or determine the given value or range. When the term "about" is used in reference to temperatures from a differential scanning calorimetry (DSC) curve (e.g., the onset of an endothermic transition, melting, etc.), each temperature value is understood to mean ±5°C, more typically ±2°C, of the given value, unless otherwise specified.
[0026] As used herein, the term "substantially the same" with respect to X-ray powder diffraction means that variations in reflection positions and relative intensities of reflections are taken into account. For example, typical accuracy of two-theta (2θ) values is within ±0.2° of a given value in 2θ, more typically within ±0.1° in 2θ. Thus, for example, under standard conditions, in most X-ray diffractometers, a reflection that typically appears at 6.9° in 2θ may appear between 6.7° and 7.1° in 2θ, more typically between 6.8° and 7.0° in 2θ. Furthermore, those skilled in the art will understand that relative reflection intensities exhibit instrument-to-instrument variability as well as variability due to crystallinity, preferred orientation, sample preparation, and other factors known to those skilled in the art, and should be interpreted only as a qualitative measure.
[0027] As used herein, when a polymorph is identified using one or more temperatures from a differential scanning calorimetry thermogram (DSC) curve (e.g., onset of an endothermic transition, melting, etc.), each of the temperature values is understood to mean ±5°C, more typically ±2°C, of the given value unless otherwise indicated.
[0028] Crystalline and amorphous forms In one aspect, provided herein are crystalline forms of Compound (I), particularly those designated Fumarate Type A, Fumarate Type B, Fumarate Type C, Fumarate Type E, Free Base Type A, Free Base Type B, Free Base Type C, Free Base Type D, Free Base Type E, Free Base Type F, Free Base Type G, HCl Salt Type A, HCl Salt Type B, Mesylate Type A, Mesylate Type B, Phosphate Type A, L-Tartrate Type A, and Adipate Type A. Also provided herein are amorphous forms of Compound (I), particularly those designated amorphous fumarate and amorphous free base. Methods for preparing the crystalline or amorphous forms, and pharmaceutical compositions comprising the crystalline or amorphous forms, are also provided.
[0029] The crystalline form of Compound (I) can be a complex of a free base and a pharmaceutically acceptable acid, or the free base. Such complexes include, but are not limited to, salts, cocrystals, or salt cocrystals. The amorphous form of Compound (I) can be a pharmaceutically acceptable salt or the free base.
[0030] As used herein, the term "crystalline form" refers to a crystalline structure in which a compound (or a salt or solvate thereof) can crystallize in various crystal packing arrangements, all of which have the same elemental composition. Different crystalline forms typically have different X-ray diffraction patterns, infrared spectra, melting points, density hardness, crystal shape, optical and electrical properties, stability, and solubility. Depending on the recrystallization solvent, crystallization rate, storage temperature, and other factors, one crystalline form may predominate. Crystalline polymorphs of a compound may be prepared by crystallization under different conditions.
[0031] As used herein, the term "polymorphic form" or "polymorphism" in the context of this specification refers to crystalline and amorphous forms as well as solvates and hydrate forms. Crystalline forms have various arrangements and / or conformations of molecules in a crystal lattice. Amorphous forms consist of irregular arrangements of molecules without a distinguishable crystal lattice. Solvates are crystalline forms that contain stoichiometric or non-stoichiometric amounts of solvent. When a drug substance exists in multiple forms, it is said to exhibit polymorphism.
[0032] As used herein, the term "complex" refers to a crystalline substance composed of two or more different molecules, one of which is an active pharmaceutical ingredient (API), in the same crystal lattice bound by ionic / non-ionic and ionic / non-covalent bonds. In the context of this specification, API may refer to Compound (I).
[0033] As used herein, the term "cocrystal" refers to a crystalline material composed of two or more different molecules (one of which is an API) within the same crystal lattice bound by non-ionic and non-covalent bonds.
[0034] As used herein, the term "salt" refers to any of a number of compounds resulting from substituting some or all of the acid hydrogens of an acid to form an ionic or ionically bonded compound.
[0035] As used herein, the term "salt co-crystal" refers to a crystalline form in which the chlorided API and coformer (or vice versa) are in the same crystal lattice bound by non-ionic and non-covalent bonds.
[0036] As used herein, the term "pharmaceutically acceptable" indicates that a substance or composition is chemically and / or toxicologically compatible with the other ingredients comprising the formulation and / or the subject being treated therewith.
[0037] As used herein, the term " pharmaceutically acceptable acid " may refer to such an acid that contains pharmaceutically acceptable anion.Preferably, examples of pharmaceutically acceptable acids described herein include, but are not limited to, hydrochloride, methanesulfonic acid, phosphoric acid, tartaric acid, fumaric acid and adipic acid.More examples of suitable acids can be found, for example, in P.H. Stahl and C.G. Wermuth, eds., Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim / Zurich: Wiley-VCH / VHCA, 2002.
[0038] As used herein, the term "pharmaceutically acceptable salts," unless otherwise indicated, includes salts that retain the biological effectiveness of the free base of the specified compound and are not biologically or otherwise undesirable. Contemplated pharmaceutically acceptable salt forms include, but are not limited to, mono-, bis-, tris-, tetrakis-, and the like. Pharmaceutically acceptable salts are non-toxic in the amounts and concentrations at which they are administered. The preparation of such salts can facilitate pharmacological use by altering the physical properties of a compound without preventing the compound from exerting its physiological effect. Useful changes in physical properties include lowering the melting point to facilitate transmucosal administration and increasing solubility to facilitate the administration of higher drug concentrations.
[0039] Pharmaceutically acceptable salts may include acid addition salts such as sulfate, chloride, hydrochloride, fumarate, maleate, phosphate, sulfamate, acetate, citrate, lactate, tartrate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, cyclohexylsulfamate, and quinate. Illustrative examples of pharmaceutically acceptable salts described herein include hydrochloride, mesylate, phosphate, tartrate, fumarate, and adipate. The salts described herein may have an acid / base molar ratio of about 0.5:1 to about 3:1, typically about 0.5:1 to about 2.5:1, and more typically about 1:1 to about 1.5:1. For example, the salts described herein can have an acid / base molar ratio of about 0.5:1, about 0.6:1, about 0.7:1, about 0.8:1, about 0.9:1, about 1:1, about 1.1:1, about 1.2:1, about 1.3:1, about 1.4:1, about 1.5:1, about 1.6:1, about 1.7:1, about 1.8:1, about 1.9:1, about 2:1, about 2.1:1, about 2.2:1, about 2.3:1, about 2.4:1 and about 2.5:1.
[0040] Pharmaceutically acceptable salts can be obtained from suitable acids such as hydrochloric acid, maleic acid, sulfuric acid, phosphoric acid, sulfamic acid, acetic acid, citric acid, lactic acid, tartaric acid, malonic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamic acid, fumaric acid, quinic acid, etc. Preferably, examples of suitable acids include hydrochloride, methanesulfonic acid, phosphoric acid, tartaric acid, fumaric acid, and adipic acid.
[0041] Pharmaceutically acceptable salts can be prepared by standard techniques.For example, the free base form of a compound can be isolated by dissolving it in a suitable solvent, such as an aqueous or aqueous alcoholic solution containing a suitable acid, and then evaporating the solution.Therefore, if a particular compound is a base, the desired pharmaceutically acceptable salt can be prepared by any suitable method available in the art, such as treating the free base with an inorganic or organic acid.
[0042] It will be understood that the crystalline or amorphous compounds described herein may exist in unsolvated or solvated forms, and that the present invention is intended to encompass all such forms.
[0043] As used herein, the terms "solvate" and "solvated" refer to solvent addition forms that contain stoichiometric or non-stoichiometric amounts of solvent.Some compounds tend to capture a certain molar ratio of solvent molecules in crystalline solid state, thus forming solvates.For example, when the solvent is water, the solvate that forms is a hydrate; when the solvent is alcohol, the solvate that forms is an alcoholate; when the solvent is acetone, the solvate that forms is an acetone solvate.A hydrate is formed by combining one or more water molecules with one molecule of a substance, with water retaining its molecular state as H2O.Examples of solvents that form solvates include, but are not limited to, water, isopropanol, ethanol, methanol, acetone, DMSO, ethyl acetate, acetic acid and ethanolamine.
[0044] As used herein, the terms "nonsolvate" and "non-solvated" indicate that the organic solvent is not incorporated into or accommodated by the solid structure, including both crystalline and amorphous structures. The nonsolvated form may still contain residual organic solvent that is not part of the solid structure but may be adsorbed to surfaces or absorbed into irregular regions of the solid structure. Typically, the nonsolvated form contains no more than 2.0 wt. %, typically no more than 1.0 wt. %, and more typically no more than 0.5 wt. % of organic solvent, based on the weight of the crystalline form. The organic solvent content may be determined by thermogravimetric analysis (TGA), e.g., by measuring weight loss in the range of 25°C to the melting point of the solid form at a heating rate of 10 K / min, and / or by gas chromatography.
[0045] Thus, in one aspect, a compound of the following structural formula: Provided herein is a crystalline form of Compound (I) represented by TIFF2026027273000003.tif33170, wherein the crystalline form is a complex of the free base with a pharmaceutically acceptable acid, or the free base.
[0046] In certain embodiments, the complex or free base is solvated or unsolvated.
[0047] In certain embodiments, the complex is a salt, or a co-crystal, or a co-crystal of a salt.
[0048] In certain embodiments, the complex has an acid / base molar ratio of about 3:1, preferably about 0.5:1 to about 2.5:1, and more preferably about 1:1 to about 1.5:1.
[0049] In certain embodiments, the pharmaceutically acceptable acid is selected from the group consisting of hydrochloride, methanesulfonic acid, phosphoric acid, tartaric acid, fumaric acid, and adipic acid.

[0114] Purpose The crystalline and amorphous forms of Compound (I) described herein may exhibit high inhibitory activity against type I receptor tyrosine kinases, particularly HER2.
[0115] As used herein, the term "inhibitory activity against type I receptor tyrosine kinase" refers to a decrease in the activity of type I receptor tyrosine kinase as a direct or indirect response to the presence of a crystalline or amorphous form of Compound (I), compared to the activity of type I receptor tyrosine kinase in the absence of the crystalline or amorphous form of Compound (I). Such a decrease in activity may be due to the direct interaction of the crystalline or amorphous form of Compound (I) with type I receptor tyrosine kinase, or may be due to the interaction of the crystalline or amorphous form of Compound (I) with one or more other factors that affect the activity of type I receptor tyrosine kinase. For example, the crystalline or amorphous form of Compound (I) described herein may decrease the activity of type I receptor tyrosine kinase by directly binding to type I receptor tyrosine kinase, by inducing (directly or indirectly) another factor to decrease the type I receptor tyrosine kinase activity, or by decreasing (directly or indirectly) the amount of type I receptor tyrosine kinase present in a cell or organism.
[0116] As a result of their inhibitory activity against type I receptor tyrosine kinases, crystalline and amorphous forms of Compound (I) are useful in therapy, for example, in the treatment of diseases or medical conditions mediated at least in part by one or more type I receptor tyrosine kinases, including cancer.
[0117] As used herein, the term "cancer" refers to or refers to a physiological condition in mammals that is typically characterized by abnormal or unregulated cell proliferation.

Seven crystalline salts were obtained: HCl salt type A, HCl salt type B, mesylate salt type A, mesylate salt type B, phosphate salt type A, L-tartrate salt type A, fumarate salt type A, and adipate salt type A. Additionally, one crystalline free base, free base type A, was observed in the screening.

Polymorph screening experiments were set up using methods including, but not limited to, slow evaporation, slow cooling, slurry, solid vapor diffusion, liquid vapor diffusion, and antisolvent addition. A total of six crystalline forms of the free base were observed during the screening and identification process, and these were designated free base types B, C, D, E, F, and G. Most forms were characterized by XRPD, TGA, DSC, and NMR. 1Characterization by H NMR revealed that free base types B and E are anhydrates, free base types C, D, F, and G are hydrates, and free base type A is an acetone solvate.
[0146] To test the interconversion relationship between free base type B and free base type C, a slurry competition experiment was conducted. Results showed that free base type B was obtained after slurrying in solvent systems with water activities (Aw) of approximately 0.4, 0.6, and 0.8 at 24 ± 3 °C, and free base type C was obtained after slurrying in HO with a water activity of approximately 1, indicating that the critical water activity between free base types B and C is in the range of 0.8–1. The interconversion relationship between anhydrous free base type B and hydrate types C / F / G was further investigated under different water activities at room temperature. Saturated solutions of free base type B were obtained via slurrying free base type B in the corresponding solvent systems overnight at room temperature. A mixture of free base types B+C+F+G was added to the corresponding saturated solution of free base type B to form a suspension. After stirring at 750 rpm for 4 days at room temperature, the suspension was sampled for XRPD. Free base type B was observed in EtOH and EtOH / H2O (aw = 0.2, 0.4, 0.6, 0.8) systems, whereas free base type G was obtained in pure H2O systems. [Example]

[0159] Example 1 Fumarate Type A of Compound (I) Compound (I) fumarate salt type A was prepared according to the following process: a) dissolving 500 mg of Compound (I) free base in approximately 10 mL of EtOAc to form a free base solution; b) Dissolve 158.6 mg of fumaric acid (charge molar ratio 1.5:1, acid / free base) in approximately 5 mL of EtOH to form an acid solution; c) Add the acid solution dropwise to the free base solution while stirring; d) adding about 13 mL of n-heptane dropwise; and then optionally seeding the mixture with crystalline form of fumarate salt Type A of Compound (I); e) stirring at about 5° C. for about 16 hours; and f) Isolating the solid by filtration and then drying the solid under vacuum at about 50°C.
[0160] The fumarate salt type A of Compound (I) is anhydrous, slightly hygroscopic rod-like crystals (as shown by PLM in Figure 5) with an acid / base stoichiometry of approximately 1.5:1, as determined by XRPD, TGA, DSC, and 1 The compound was characterized by H NMR.
