Description

[Technical Field]

[0001] This application claims priority from Chinese Patent Application No. 2022116420036, filed on December 20, 2022. The above Chinese patent application is incorporated herein by reference in its entirety.

[0002] (Technical field) The present disclosure belongs to the field of pharmaceutical technology and relates to a crystalline form of a KRAS G12D inhibitor and a method for preparing the same. [Background technology]

[0003] RAS is one of the oncogenic genes with the highest mutation rates in tumors, with approximately 30% of human malignancies associated with RAS gene mutations. The RAS family includes KRAS, NRAS, and HRAS, of which KRAS mutations are the most common, accounting for approximately 85% of cases. KRAS mutations are common in solid tumors, and are frequently present in the three most lethal human cancers: lung cancer (17%), colorectal cancer (33%), and pancreatic cancer (61%). Among KRAS gene mutations, 97% involve mutations at the 12th or 13th amino acid residue, with G12D being the most critical mutation. Data analysis of Western populations showed that the G12D mutation accounts for 36%, 12%, and 4% of pancreatic, colorectal, and non-small cell lung cancer patients, respectively.

[0004] After activation, KRAS regulates various functions such as cell proliferation, survival, migration, and metabolism through many downstream signaling pathways, including RAF-MEK-ERK, PI3K-AKT-mTOR, and TIAM1-RAc. After the KRAS gene is mutated, the protein remains persistently activated, which continuously activates downstream signaling pathways and promotes tumor development.

[0005] The KRAS protein has long been considered an undruggable drug target because it lacks a traditional small molecule binding site on its surface and is highly resistant to inhibition due to its ultra-high affinity for guanylate. However, due to the importance and ubiquity of aberrant KRAS activation in cancer progression, KRAS has been and remains a highly sought-after target for drug development. Currently, there is a lack of KRAS inhibitors effective against other mutations other than KRAS G12C inhibitors, meaning that most patients with KRAS mutations remain without a therapeutic option. Because G12D is a widely overexpressed mutation in various tumors, the development of inhibitors targeting it is of great clinical significance.

[0006] Patent application PCT / CN2022 / 100016 provides a new KRAS G12D inhibitor (Formula I) with relatively good pharmacological activity. To meet the needs of drug development, its crystalline form needs to be studied. The crystalline form prepared in this disclosure has good physicochemical stability and can meet the needs of drug development and storage.

[0085] The term "X-ray powder diffraction pattern or XRPD" as used herein means that, based on the Bragg equation, 2d sin θ=nλ (where λ is the wavelength of the X-ray, the diffraction order n is any positive integer, and generally the first-order diffraction peak is taken, where n=1), when an X-ray is incident on a crystal at a sweep angle θ (the complement of the incident angle, also called the Bragg angle), or on a certain atomic plane having an interplanar distance of d in some crystal samples, the Bragg equation can be satisfied, and thus the X-ray powder diffraction pattern of this group can be measured.

[0086] "X-ray powder diffraction pattern or XRPD" as referred to in this disclosure is a pattern obtained by using Cu-Kα radiation in an X-ray powder diffractometer.

[0087] "Differential scanning calorimetry or DSC" as used in this disclosure refers to the measurement of temperature and heat flow differences between a sample and a reference during ramping or isothermal heating of the sample to characterize all physical and chemical changes associated with thermal effects and obtain phase transition information of the sample.

[0088] "Thermogravimetric analysis or TGA" as used in this disclosure means the continuous measurement of the change in mass of a sample with temperature or time under a programmed temperature.

[0089] "2θ or 2θ angle" as used in this disclosure refers to the diffraction angle, where θ is the Bragg angle, and is expressed in ° or degrees, with an error range of ±0.3, ±0.2, or ±0.1 for 2θ.

[0090] The "lattice spacing or lattice spacing (d value)" in this disclosure refers to selecting three unit vectors a, b, and c that are not parallel to each other in a space lattice and connect two adjacent lattice points, and dividing the lattice into parallel parallelepiped units using them, which are called lattice spacing. The space lattice is divided according to the connecting lines of the determined parallelepiped units, resulting in a set of linear lattices called a space lattice or a crystal lattice. The lattice and the crystal lattice reflect the periodicity of the crystal structure with geometric points and lines, respectively, and different crystal planes have different interplanar spacings (i.e., the distance between two adjacent parallel crystal planes), and the unit is Å or angstroms.
