Description

Crystalline form of CGRP antagonists Technical Field

[0001] This application relates to the crystalline polymorphic form of the CGRP antagonist (R)-N-(3-(7-methyl-1H-indazol-5-yl)-1-(4-(1-methylpiperidin-4-yl)piperazin-1-yl)-1-oxopropyl-2-yl)-4-(7-oxo-3,4,7,8-tetrahydro-2H-thiaro[2,3-b]pyridin-6-yl)piperidine-1-carboxamide, methods for its preparation, pharmaceutical compositions comprising said crystalline form, and its use in the treatment of related diseases. Background Technology

[0002] Migraine is a common neurovascular disease, mainly characterized by recurrent, mostly unilateral, moderate to severe throbbing headaches that usually last 4 to 72 hours and are accompanied by symptoms such as nausea, vomiting, and sensitivity to sound and light (phonophobia and photophobia) [1]. Before a migraine attack, there is often a period of sensory disturbance, which is called migraine with aura. One-seventh of migraine patients in my country have aura symptoms [2]. The main types of aura include visual disturbances such as scotomas, bright spots and flashes of light, as well as olfactory abnormalities, dizziness, tinnitus, and difficulty in speech. Currently, more than 1 billion people worldwide are affected by migraine [3]. The consultation rate of migraine patients in my country is only 52.9%, and the correct diagnosis rate by physicians is only 13.8%. There is also a general lack of preventive treatment and overuse of analgesics [2]. Migraine attacks can last for hours or even days and may seriously affect normal daily activities, which creates a significant need for acute treatments that can quickly relieve headaches. In recent years, with the progress of migraine research at home and abroad, new therapeutic targets such as calcitonin gene-related peptide (CGRP) have emerged, enriching the treatment methods for migraine.

[0003] Calcitonin gene-related peptide (CGRP) is a polypeptide composed of 37 amino acids. Its N-terminal disulfide bond and amino-terminal C-terminus play an important role in activating receptors [4]. CGRP is mainly located in the trigeminal ganglion, C-fibers and Aδ fibers in the dorsal root ganglion, and the central nervous system [5]. There are two forms of CGRP in the human body, namely α-CGRP and β-CGRP, which differ by only 1-3 amino acids in different species. α-CGRP is highly expressed in sensory neurons, while β-CGRP mainly functions in the enteric nervous system [6]. CGRP exerts its biological function by binding to receptors on the membrane. The CGRP receptor is mainly composed of calcitonin receptor-like receptor (CLR) and receptor activity modifying protein 1 (RAMP1), and also requires receptor component protein (RCP) to perform signal transduction function [7]. CGRP mainly plays a role in vasodilating in the body. Studies suggest that CGRP plays an important role in the occurrence and development of migraine. Clinical evidence shows that the CGRP content in the jugular vein of migraine patients increases during an attack. Intravenous injection of CGRP can cause moderate to severe headache attacks, while the use of CGRP antagonists can relieve migraine pain and related symptoms[4].

[0004] PCT application PCT / CN2024 / 090110 provides a series of oxopyridine compounds with aliphatic or heterocyclic structures as CGRP antagonists, which can be used for the prevention and treatment of CGRP-mediated diseases, particularly migraine and neurogenic headache. Specifically, in Example 6 of this application, compound (R)-N-(3-(7-methyl-1H-indazol-5-yl)-1-(4-(1-methylpiperidin-4-yl)piperazin-1-yl)-1-oxopropyl-2-yl)-4-(7-oxo-3,4,7,8-tetrahydro-2H-thiarano[2,3-b]pyridin-6-yl)piperidin-1-carboxamide is provided, which has the following structure and is referred to herein as compound I:

[0005] As demonstrated in PCT application PCT / CN2024 / 090110, the compound of formula I exhibits excellent CGRP antagonistic activity.

[0006] The solid-state form of the active pharmaceutical ingredient (API) of a particular drug is often a crucial factor determining the ease of preparation, hygroscopicity, stability, solubility, storage stability, ease of formulation, dissolution rate in gastrointestinal fluids, and bioavailability in vivo. Crystalline form refers to the different lattice arrangements of substances of the same composition, resulting in different thermodynamic properties and stability for specific crystalline forms. Crystalline forms may also include different hydrates or solvates of the same compound. Determining which form is preferred requires comparing numerous properties of these forms and selecting the preferred form based on many physical property variables. In some cases, when certain aspects (e.g., ease of preparation, stability, etc.) are considered crucial, one form may be preferred, while in other cases, a different form may be preferred to obtain a higher dissolution rate and / or higher bioavailability.

[0007] Therefore, the ability of a chemical substance to crystallize into multiple crystalline forms can profoundly affect a drug's shelf life, solubility, formulation characteristics, and processing properties. Furthermore, drug efficacy can be influenced by molecular polymorphism. Different polymorphs may have varying absorption rates in vivo, leading to lower or higher than expected biological activity. The occurrence of unknown crystalline forms during manufacturing can also have significant impacts.

[0008] It is currently impossible to predict whether a particular compound or its salt will form polymorphs, whether those polymorphs are suitable for commercial use in therapeutic compositions, or which polymorphs will exhibit the desired properties. However, understanding which crystal forms a drug will produce under specific conditions allows researchers to optimize the desired properties of a compound, such as solubility, formulation characteristics, processing characteristics, and shelf life. Understanding these factors early in new drug development may mean producing more active, more stable, or cheaper drugs.

The test compound inhibits the binding of CGRP to receptors, inhibiting the increase in blood flow caused by the release of CGRP. Blood flow is detected by a blood flow meter to reflect the efficacy of the drug.

[0097] Species: Crab-eating macaque, male (5-8 kg), Animal use permit: SYXK(Su)2019-0004, hair removal treatment was performed 3 days before the experiment.

[0098] 2.2 Sample configuration:

[0099] Accurately weigh an appropriate amount of drug, dissolve it in sterile physiological saline, and use sonication and vortexing to mix and dissolve it thoroughly to obtain a 0.05 mg / ml drug solution for intravenous (IV) administration.

[0100] 2.3 Pre-test phase: After anesthetizing the animals, a flowmeter was used to scan the blood flow on the inner side of the forearm, and an O-ring was placed on the inner side of the arm, avoiding obvious blood vessels. After confirming the position of the rubber ring, the blood flow rate inside the ring was scanned as the baseline blood flow value. Subsequently, 2 mg of capsaicin was applied inside the rubber ring, and the blood flowmeter recorded the blood flow rate at 10 min, 20 min, and 30 min after capsaicin treatment.

[0101] 2.4 Administration phase: After anesthetizing the monkeys, a rubber band was placed on the same part of the arm. After collecting baseline blood flow data, the test compound (dose: 0.05 mg / kg) was injected intravenously at a dose of 1 ml / kg. After administration, 2 mg of capsaicin was applied to the rubber band. Blood flow was recorded at 10 min, 20 min and 30 min after capsaicin treatment using a blood flow meter.

[0102] 2.5 Data Processing: Blood flow during the pre-test phase is denoted as P, and blood flow in the rubber band at time t is denoted as Pt. t Baseline blood flow is denoted as P0; blood flow during the drug administration phase is denoted as D; and blood flow through the rubber band at time t is denoted as D0. t If the baseline blood flow is denoted as D0, then the blood flow inhibition rate at time t is I. t The calculation formula is as follows: I t=((P) t –P0) / P0–(D t –D0) / D0)*100%

[0103] 3. Experimental Results:

[0123] Invention Details

[0124] definition

[0125] Unless otherwise stated or separately defined, the terms used in the specification and claims shall have the following meanings.

[0126] "Antagonist" refers to a drug that does not have intrinsic activity but can block the action mediated by receptor agonists after binding to the receptor.

[0127] As used herein, the term “pharmaceutical acceptable” means a molecular entity or composition that is approved or can be approved by the relevant authorities of each country, or is listed in a generally accepted pharmacopoeia for use in animals and more specifically in humans, or that will not produce adverse, allergic or other adverse reactions when administered appropriately to animals, such as humans.

[0128] As used herein, the term "substantially pure" when applied to a particular crystal form of a compound of Formula I means having a crystal form purity of more than 50% by weight, for example, more than 60% by weight, more than 70% by weight, more than 80% by weight, more than 90% by weight, more than 95% by weight, more than 97% by weight, and more preferably more than 99% by weight.

[0129] As used in this article, "polymorphism" or "crystal form" refers to a crystal form that has the same chemical composition but different spatial arrangements of molecules that form crystals.

[0130] As used herein, "solvent" or "solvent compound" refers to a crystalline form of a molecule that further comprises molecules of one or more solvents bound to a lattice structure. Solvent molecules in a solvate may exist in a regular and / or disordered arrangement. A solvate may contain stoichiometric or non-stoichiometric amounts of solvent molecules. For example, a solvate with non-stoichiometric amounts of solvent molecules may arise from the partial loss of solvent from the solvate. The solvent may be water, in which case the solvate may be referred to as a hydrate.

[0131] As used in this article, "amorphous" refers to a solid form of molecules that is not crystalline. Amorphous solids do not exhibit defined X-ray diffraction patterns.

[0132] As used herein, the terms “about” and “substantially” indicate that their values ​​can vary for characteristics such as endothermic, endothermic peaks, exothermic, baseline shifts, etc. Regarding X-ray diffraction peak positions, “about” or “substantially” means taking into account typical peak position and intensity variability. For example, those skilled in the art will understand that peak position (2θ) can indicate variability between certain devices, typically up to 0.2°. Furthermore, those skilled in the art will understand that relative peak intensities will show variability between devices as well as variability due to crystallinity, preferred orientation, prepared sample surface, and other factors known to those skilled in the art, and should be used only as qualitative measurements. For DSC, the observed temperature variation will depend on the rate of temperature change and the sample preparation technique and the specific instrument used. Therefore, the endothermic / melting point values ​​reported herein for DSC / TGA thermal analysis plots can vary by ±5°C (and are still considered characteristic of the specific crystalline form described herein). When used in the context of other characteristics such as weight percentage (by weight%) and reaction temperature, the term “about” indicates a variation of ±5%.

[0133] Zavegepant, also known as Vazegepant, is a nasal spray that was launched in the United States in March 2023 by Pfizer under the brand name ZAVZPRET.

[0134] Unless otherwise stated, the terms “comprise”, “comprises”, and “comprising” or their equivalents (contain, contain, containing, include, include, including) used herein are open-ended expressions, meaning that they may cover other unspecified elements, components, and steps in addition to those listed.

[0135] Unless the context clearly indicates otherwise, singular terms in this document cover the plural referents, and vice versa.

[0136] The term “prevention” means administering the crystalline, amorphous or compositional form of the compound of Formula I described in this application to prevent the disease described in this application or one or more symptoms associated with the disease, including: preventing the occurrence of the disease or disease state in a subject, particularly when such subjects are susceptible to the disease state but have not yet been diagnosed with the disease state.

[0137] The term "treatment" means administering a crystalline, amorphous, or compositional form of a compound of Formula I described in this application to improve or eliminate one or more symptoms of the disease described in this application or related to the disease, including: suppressing the disease or disease state, i.e., curbing its development, or causing the disease or disease state to subside.

[0138] The term "relief" refers to administering the crystalline, amorphous, or compositional form of the compound of Formula I described in this application to reduce or decrease one or more symptoms of the disease described in this application or related to the disease, including: reducing the severity of the disease described in this application, delaying the progression of the disease, or reducing the frequency or duration of the disease.

[0139] The term "therapeutic effective amount" means (i) the amount of a crystalline, amorphous, or compositional form of a compound of Formula I described herein used to treat the specific disease, condition, or disorder described herein, (ii) reduce, improve, or eliminate one or more symptoms of the specific disease, condition, or disorder described herein, or (iii) prevent or delay the onset of one or more symptoms of the specific disease, condition, or disorder described herein. The amount of a crystalline, amorphous, or compositional form of a compound of Formula I described herein constituting a "therapeutic effective amount" varies depending on the crystalline, amorphous, or compositional form of the compound of Formula I, the disease state and its severity, the route of administration, and the age of the subject to be treated, but may routinely be determined by a person skilled in the art based on their own knowledge and the content of this disclosure.

[0140] Unless otherwise stated, the terms “patient,” “subject,” and “individual” are used interchangeably in this document and refer to human or non-human animals (e.g., primates, rodents, etc.), such as, but not limited to, mice, rats, guinea pigs, dogs, pigs, chickens, rabbits, monkeys (e.g., rhesus monkeys, cynomolgus monkeys, etc.), humans, etc.

[0141] The term "pharmaceutically acceptable carrier" refers to carriers, such as excipients, diluents, or transporters, that do not significantly irritate the organism and do not impair the biological activity and properties of the active compound.

[0142] For purposes of description and disclosure, all patents, patent applications and other publications are expressly incorporated herein by reference. These publications are provided only because their publication predates the filing date of this application. All statements regarding the dates of these documents or representations of their contents are based on information available to the applicant and do not constitute any admission of the accuracy of the dates or contents of these documents.
