Description

[Technical Field]

[0001] The present invention relates to a solid form of N-(2-chloro-4-(trifluoromethyl)phenyl)-2-(2-(3,6-dihydro-2H-pyran-4-yl)-5-ethyl-6-(4-(5-hydroxy-6-methylpyrimidine-4-carbonyl)piperazin-1-yl)-7-oxo-[1,2,4]triazolo[1,5-a]pyrimidin-4(7H)-yl)acetamide, hereinafter referred to as "Compound A." Compound A is an inhibitor of Werner syndrome RecQ DNA helicase (WRN), and therefore can be used, inter alia, as a pharmaceutical agent for the treatment of diseases such as cancer, particularly cancers treated by inhibition of WRN. The compound is particularly intended for use in the treatment of cancers characterized as microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR). [Background technology]

[0002] Loss of DNA mismatch repair (MMR) is a common initiating event in cancer development, occurring in 10–30% of colorectal, endometrial, ovarian, and gastric cancers (Aaltonen, LA et al., Clues to the pathogenesis of familial colorectal cancer, Science 260, 812–816 (1993); Bonneville R et al., Landscape of Microsatellite Instability Across 39 Cancer Types. JCO Precis Oncol. 1:PO.17.00073 (2017)). Cancers with MMR loss have high mutational burden and frequent deletion and insertion events in repetitive DNA tracts, a phenotype known as microsatellite instability (MSI). While progress has been made in the treatment of microsatellite instability-high (MSI-H) cancers, with pembrolizumab (anti-PD1) recently approved for the first-line treatment of MSI-H-dMMR metastatic colorectal cancer after it was demonstrated to result in significantly longer progression-free survival compared with chemotherapy, significant unmet medical needs remain in CRC and other MSI-H indications (Andre T., et al. Pembrolizumab in Microsatellite-Instability-High Advanced Colorectal Cancer. N Engl J Med 383(23):2207-2218(2020)).Multiple large-scale functional genomic screens of large panels of cell lines, including Novartis, using 398 cell lines from the Cancer Cell Line Encyclopedia (CCLE) (McDonald ER et al., Project DRIVE: A Compendium of Cancer Dependencies and Synthetic Lethal Relationships Uncovered by Large-Scale, Deep RNAi Screening. Cell 170(3):577-592 (2017)) have identified the selective requirement of the Werner syndrome RecQ helicase (WRN) for survival in mismatch repair-deficient cell lines that have become MSI-H (Behan, FM et al., Prioritization of cancer therapeutic targets using CRISPR-Cas9 screens. Nature 568, 511-516 (2019); Chan, EM et al., WRN helicase is a synthetic lethal target in microsatellite unstable cancers. Nature 568, 551-556 (2019). Kategaya, L., Perumal, SK, Hager, JH & Belmont, LD. Werner syndrome helicase is required for the survival of cancer cells with microsatellite instability. iScience 13, 488-497 (2019). Lieb, S. et al. Werner syndrome helicase is a selective vulnerability of microsatellite instability-high tumor cells. eLife 8, e43333 (2019). WRN is synthetically lethal in MSI cancers.Depletion of WRN leads to antiproliferative effects, activating multiple DNA damage signaling markers, inducing cell cycle arrest, and apoptosis in MMR cancer models, but not in cancer cells with an intact MMR pathway. These findings indicate that WRN provides DNA repair and maintenance functions essential for cell survival in MSI cancers. Recently, the mechanism of WRN dependence has been elucidated. Dinucleotide TA repeats have been shown to be selectively unstable and undergo large expansions in MSI cells. These expanded TA repeats form secondary DNA structures that require WRN helicase for unwinding (van Wietmarschen, N. et al. Repeat expansions confer WRN dependence in microsatellite-unstable cancers. Nature 586, 292-298, 2020). In the absence of WRN (or when WRN helicase is inhibited), expanded TA repeats in MSI cells undergo nuclease cleavage and chromosome breakage. Therefore, inhibiting WRN helicase is an attractive strategy for treating mismatch repair-deficient cancers.

[0006] Different solid-state forms of an active pharmaceutical ingredient often have different properties. Differences in the physicochemical properties of the solid forms can play an important role in improving pharmaceutical compositions; for example, pharmaceutical formulations with improved dissolution profiles or improved stability or shelf life may become available through improvements in the solid-state forms of the active pharmaceutical ingredient. The processing or handling of the active pharmaceutical ingredient during the formulation process may also be improved. Thus, novel solid-state forms of the active pharmaceutical ingredient may have desirable processing properties. They may be easier to handle, more suitable for storage, and / or allow for better purification compared to previously known solid forms. Thus, the present invention provides alternative solid-state forms of compound A having different physicochemical properties. Summary of the Invention

[0074] definition In the context of the present invention, the following definitions have the indicated meanings unless expressly stated otherwise.

[0075] As used herein, the term "room temperature" refers to a temperature in the range of 20-30°C.

[0076] As used herein, with respect to X-ray powder diffraction, the term "reflection" refers to a peak in an X-ray diffractogram at a specific diffraction angle (Bragg angle) caused by constructive interference from X-rays scattered by parallel planes of atoms in a solid material that are distributed in a regularly repeating pattern with long-range positional order. Such solid materials are classified as crystalline, while amorphous materials are defined as solid materials that lack long-range order and exhibit only short-range order, resulting in widespread scattering. According to the literature, long-range order spans, for example, approximately 100-1000 atoms, while short-range order spans only a few atoms (see "Fundamentals of Powder Diffraction and Structural Characterization of Materials," by Vitalij K. Pecharsky and Peter Y. Zavalij, Kluwer Academic Publishers, 2003, p. 3).

[0077] With respect to X-ray powder diffraction, the terms "essentially the same" or "substantially the same" mean that variations in the positions of reflections and the relative intensities of reflections should be taken into account. For example, typical 2-theta values ​​have an accuracy within ±0.2° 2-theta, preferably within ±0.1° 2-theta. Furthermore, one skilled in the art will understand that relative reflection intensities represent variations due to instrument-to-instrument variations, as well as crystallinity, preferred orientation, particle size, sample preparation, and other factors known to those skilled in the art, and should be viewed only as a qualitative measure.

[0078] The crystalline forms of Compound A of the present invention may be referred to herein as being characterized by graphical data "shown in" the drawings. Such data may include, for example, X-ray powder diffraction. Those skilled in the art will appreciate that factors such as variations in instrument type, sample orientation, sample concentration, and sample purity may lead to minor variations in such data when presented in graphical form, such as variations in the exact peak positions and peak intensities. However, comparison of the graphical data of the drawings herein with graphical data generated for another or unknown solid form, and confirmation that the two sets of graphical data relate to the same crystalline form, is well within the knowledge of those skilled in the art.

[0079] The terms "solid form" or "solid state form," as used herein, refer to any crystalline and / or amorphous phase of a compound.

[0080] As used herein, the term "amorphous" refers to a non-crystalline solid form of a compound. Amorphous compounds do not possess long-range order and do not exhibit X-ray powder diffraction patterns with distinct reflections.

[0081] "X-ray powder diffraction pattern" means an X-ray powder diffractogram.

[0082] As used herein, the term "variant" is used to refer to different crystalline forms that have the same chemical composition but differ in the spatial arrangement of the molecules, atoms, and / or ions that form the crystal.

[0083] The term "hydrate," as used herein, refers to a crystalline solid in which water is associated with or accommodated by the crystal structure, e.g., a crystalline solid in which water is part of the crystal structure or is enclosed within the crystal (water inclusions). Therefore, water can be present in stoichiometric or non-stoichiometric amounts. When water is present in stoichiometric amounts, the hydrate can be designated by adding a Greek multiple prefix. For example, a hydrate can be referred to as a hemihydrate or monohydrate, depending on the water / compound stoichiometry. Water content can be measured, for example, by Karl Fischer coulometry.

[0084] As used herein, "solvate" refers to a crystalline form of a molecule, atom, and / or ion that further comprises one or more solvent molecules incorporated into the crystal lattice structure. The solvent molecules in a solvate may be in an ordered and / or disordered arrangement. A solvate may comprise either a stoichiometric or non-stoichiometric amount of solvent molecules. For example, a solvate with a non-stoichiometric amount of solvent molecules may result from partial loss of solvent from the solvate. A solvate may occur as a dimer or oligomer containing more than one molecule or compound A within the crystal lattice structure.

[0085] The term "anhydrous form" or "anhydrous" as used herein refers to a crystalline solid in which water is not associated with or accommodated by the crystal structure. The anhydrous form may still contain residual water that is not part of the crystal structure but may be adsorbed onto the surface of the crystal or absorbed into disordered regions of the crystal. Typically, the anhydrous form does not contain more than 2.0 wt. % water, preferably 1.0 wt. % or less water, based on the weight of the crystalline form.

[0086] The term "effective amount," as used herein with respect to Compound A, encompasses an amount of Compound A that produces the desired therapeutic and / or prophylactic effect.

[0087] As used herein, the term "about" means within a statistically significant range of a value. Such a range can be within an order of magnitude, typically within 10%, more typically within 5%, even more typically within 1%, and most typically within 0.1% of a given value or range. Such a range may also be within experimental error typical of the standard method used to measure and / or determine a given value or range.

[0088] As used herein, "substantially pure" when used with respect to a form means a compound having a purity of greater than 90 wt.%, e.g., greater than 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99 wt.%, and even equal to about 100 wt.%, based on the weight of the compound. The remaining material includes other forms of the compound and / or reaction and / or process impurities resulting from its preparation. For example, a crystalline form of Compound A can be considered substantially pure in that it has a purity of greater than 90 wt.%, as measured by means currently known and generally accepted in the art, with the remaining less than 10 wt.% material including other forms of Compound A and / or reaction and / or process impurities.

[0089] The term "pharmaceutically acceptable excipient," as used herein, refers to a substance that does not exhibit significant pharmacological activity at a given dose and that is added to a pharmaceutical composition in addition to an active pharmaceutical ingredient. Excipients can function as vehicles, diluents, release agents, disintegrants, dissolution modifiers, absorption enhancers, stabilizers, or manufacturing aids, among others. Excipients can include fillers (diluents), binders, disintegrants, lubricants, and glidants.

[0090] Biological Assays, Data and Synthesis The activity of Compound A according to the present invention was evaluated using in vitro and in vivo methods described in published patent application WO 2022 / 249060, in which activity data and synthetic routes for the compounds of Examples 42 and 123 (Compound A) are described.
