Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 63 / 435,496, filed December 27, 2022, U.S. Provisional Patent Application No. 63 / 585,565, filed September 26, 2023, and U.S. Provisional Patent Application No. 63 / 593,454, filed October 26, 2023, the contents of which are incorporated herein by reference in their entirety.

[0002] The present disclosure generally relates to a V The present invention relates to a therapeutic agent that may be useful as a β8 integrin inhibitor. The therapeutic agent may be used for the treatment or prophylactic treatment of fibrosis, such as idiopathic pulmonary fibrosis (IPF) and nonspecific interstitial pneumonia (NSIP). The therapeutic agent may also be used for the treatment of cancer. [Background technology]

[0003] Fibrosis, a pathological hallmark of many diseases, results from the dysfunction of the body's natural ability to repair damaged tissue. If left untreated, fibrosis can lead to scarring of vital organs, causing irreparable damage and eventual organ failure.

[0004] Patients with nonalcoholic fatty liver disease (NAFLD) can progress from simple steatosis to nonalcoholic steatohepatitis (NASH) and then to fibrosis. While early-stage liver fibrosis is reversible, progressive liver fibrosis can lead to cirrhosis.

[0005] Renal fibrosis, characterized by glomerular sclerosis and tubulointerstitial fibrosis, is a common and final manifestation of a wide variety of chronic kidney diseases (CKD). Regardless of the initial cause, progressive CKD often results in extensive tissue scarring that leads to the destruction of the renal parenchyma, culminating in end-stage renal failure, a devastating condition requiring dialysis or renal replacement.

[0006] Scleroderma encompasses a complex and diverse range of conditions characterized by fibrosis, vascular degeneration, and autoimmunity. The spectrum of scleroderma disorders shares the common feature of fibrosis, resulting in hardening or thickening of the skin. In some patients, this hardening occurs in limited areas, but in others, it can spread to other major organs.

[0007] Cardiac structural remodeling after myocardial infarction is associated with an inflammatory response, resulting in scar formation at the infarct site. This scar formation is the result of fibrous tissue deposition and can lead to a decline in cardiac function and disruption of electrical activity within the heart.

[0008] Crohn's disease is a chronic condition of unknown cause that tends to progress despite medical or surgical treatment. Intestinal fibrosis is one of the most common complications of Crohn's disease, resulting in the formation of strictures in the small intestine and colon.

[0009] Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive fibrotic disease of unknown cause that occurs in adults and is limited to the lungs. In IPF, lung tissue thickens, stiffens, and scars. As pulmonary fibrosis progresses, the lungs have difficulty pumping oxygen into the bloodstream, preventing organs from receiving the oxygen they need to function properly. IPF currently affects approximately 200,000 people in the United States and causes 40,000 deaths annually. Patients diagnosed with IPF experience progressive shortness of breath, eventually leading to complete respiratory failure.

[0010] Primary biliary cholangitis (PBC), also known as primary biliary cirrhosis, is a chronic liver disease that causes liver damage and fibrosis. PBC results from the slow and progressive destruction of the liver's small bile ducts, causing bile and other toxins to accumulate in the liver, a condition called cholestasis. Over time, scarring and fibrosis occur in both the liver and biliary tract.

[0011] Nonspecific interstitial pneumonia (NSIP) is a rare disease that affects the tissues that surround and separate the tiny air sacs in the lungs. These air sacs, called alveoli, are where oxygen and carbon dioxide are exchanged between the lungs and the bloodstream. Interstitial pneumonia is a disease in which the mesh-like walls of the alveoli become inflamed. The pleura (the thin covering that protects and cushions the lungs and their individual lobes) can also become inflamed. There are two main forms of NSIP: cellular and fibrotic. The cellular form is primarily defined by inflammation of interstitial cells. The fibrotic form is defined by thickening and scarring of lung tissue. This scarring, known as fibrosis, is irreversible. Thickening and scarring of lung tissue prevents the lungs from functioning effectively, leading to inefficient breathing and decreased blood oxygen levels. (Kim et al.,Proc.Am.Thorac.Soc.(2006)3:285-292;Lynch,D.,Radiology(2001)221:583-584;Kinder et al.,Am.J.Respir.Crit.Care Med.(2007)176:691-697)

[0012] Biliary atresia (BA) is a fibroobstructive cholangiopathy that affects approximately 1 in 5,000–18,000 infants, causing inflammation that leads to end-stage liver disease. Patients typically die by the age of 2 years without surgical intervention. A hepatic portoenterostomy can be performed to restore biliary drainage. However, even with restored biliary drainage, almost all patients develop liver fibrosis and require a liver transplant to survive (see Mohanty et al., “Rotavirus Reassortant-Induced Murine Model of Liver Fibrosis Parallels Human Biliary Atresia,” Hepatology 71:1316 (2020)).

[0013] Ocular fibrosis encompasses numerous ocular disorders. For example, TGFβ signaling in epithelial cells has been shown to induce epithelial-mesenchymal transition (EMT), resulting in fibrosis similar to cataract formation. Examples include anterior subcapsular cataract (ASC) and posterior capsule opacification (PCO), which can occur after cataract surgery. Research has shown that TGFβ-induced EMT is involved in the wound healing response of lens epithelial cells and can induce the expression of various extracellular matrix proteins and integrins associated with fibrosis, resulting in the production of myofibroblasts and lens fiber cells expressing α-smooth muscle actin (α-SMA), which can cause visual impairment.

[0014] Currently, there are limited treatment courses available, with no options on the market proven to improve long-term patient survival or symptom outcomes. There remains a need for treatments for fibrotic diseases.

[0015] α V β8 integrin is expressed in epithelial cells, binds to the latent peptide of transforming growth factor β1 (TGFβ1), and mediates TGFβ1 activation. Its expression level is significantly increased after lung and bile duct cell injury, and it plays an important role in tissue fibrosis in vivo. Increased levels are also associated with increased mortality in patients with IPF and NSIP.

[0016] Primary sclerosing cholangitis (PSC) involves bile duct inflammation and fibrosis that obstructs the bile ducts, resulting in obstruction of bile flow to the intestine, leading to liver cirrhosis and subsequent complications such as liver failure and liver cancer. αvβ6 expression is elevated in the liver and bile ducts of PSC patients.

An effective amount may be considered in relation to the administration of one or more therapeutic agents (e.g., a compound, or a pharmaceutically acceptable salt thereof), and a single agent may be considered to be administered in an effective amount if a desired or beneficial result can be achieved or is achieved together with one or more other agents. The appropriate dose of any co-administered compound may optionally be reduced due to the combined effect (e.g., additive or synergistic) of the compounds.

[0091] A "therapeutically effective amount" refers to that amount of a compound or salt thereof sufficient to produce a desired therapeutic effect.

[0092] As used herein, "unit dosage form" refers to physically discrete units suitable as unitary dosages, each containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Unit dosage forms may include monotherapy or combination therapy.

[0093] As used herein, the term "controlled release" refers to a drug-containing formulation or portion thereof in which the release of the drug is not immediate; i.e., administration of a "controlled release" formulation does not result in immediate release of the drug into the absorption pool. The term encompasses depot formulations designed to gradually release the drug compound over an extended period of time. Controlled release formulations can include a wide variety of drug delivery systems and generally involve mixing the drug compound with a carrier, polymer, or other compound having the desired release characteristics (e.g., pH-dependent or pH-independent solubility, varying degrees of water solubility, etc.) and formulating the mixture according to the desired delivery route (e.g., coated capsules, implantable reservoirs, injectable solutions containing biodegradable capsules, etc.).

[0094] As used herein, the term "composition" or "pharmaceutical composition" refers to a combination of an active agent with an inert or active excipient or carrier, making the composition particularly suitable for diagnostic or therapeutic use in vivo or ex vivo. Pharmaceutical compositions can be prepared by known pharmaceutical methods. Suitable compositions, excipients, or carriers can be found, for example, in Remington: The Science and Practice of Pharmacy, Lippincott Williams & Wilkins, 2002. st ed. (2005), which is incorporated herein by reference in its entirety.

[0095] As used herein, "pharmaceutically acceptable" or "pharmacologically acceptable" means that the material is not biologically or otherwise undesirable, e.g., the material may be incorporated into a pharmaceutical composition administered to a patient without causing significant undesired biological effects or interacting adversely with any of the other components of the composition in which it is contained. Pharmaceutically acceptable carriers or excipients preferably have met required standards of toxicology and manufacturing testing and / or are listed in the Inactive Ingredient Guide prepared by the U.S. Food and Drug Administration.

[0096] A "pharmaceutically acceptable salt" is a salt that retains at least some of the biological activity of the free (non-salt) compound and can be administered to an individual as a drug or pharmaceutical. See, for example, Handbook of Pharmaceutical Salts Properties, Selection, and Use, International Union of Pure and Applied Chemistry, John Wiley & Sons (2008), the entire contents of which are incorporated herein by reference. Such salts include, for example, (1) acid addition salts formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, etc., or with organic acids such as acetic acid, oxalic acid, propionic acid, succinic acid, maleic acid, tartaric acid, etc.; (2) salts formed when an acidic proton present in the parent compound is replaced with a metal ion, for example, an alkali metal ion, an alkaline earth ion, or an aluminum ion, or when coordinated with an organic base. Acceptable organic bases include ethanolamine, diethanolamine, triethanolamine, etc. Acceptable inorganic bases which can be used to prepare salts include aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, etc. Pharmaceutically acceptable salts can be prepared in situ during the manufacturing process, or by separately reacting the purified compound in its organic acid or organic base form with a suitable organic or inorganic base or acid, respectively, and isolating the salt thereby formed during subsequent purification.

[0097] As used herein, the term "excipient" refers to an inactive or non-active substance that can be used in the manufacture of a drug or pharmaceutical product, such as a tablet, that contains a compound as an active ingredient. See, e.g., Handbook of Pharmaceutical Excipients.6 thEdition, Pharmaceutical Press (2008), which is incorporated herein by reference in its entirety. The term excipient can encompass a variety of substances, including, but not limited to, binders, disintegrants, coatings, compression / encapsulation aids, creams or lotions, lubricants, parenteral solutions, chewable materials, sweeteners or flavoring agents, suspending / gelling agents, or any substance used as a wet granulator. Binders include, for example, carbomer, povidone, xanthan gum, etc.; coatings include, for example, cellulose acetate phthalate, ethyl cellulose, gellan gum, maltodextrin, enteric coatings, etc.; compression / encapsulation aids include, for example, calcium carbonate, dextrose, fructose dc (dc = "directly compressible"), honey dc, lactose (anhydrous or monohydrate; optionally in combination with aspartame, cellulose, or microcrystalline cellulose), starch dc, sucrose, etc.; disintegrants include, for example, croscarmellose sodium, gellan gum, sodium starch glycolate, etc.; creams or lotions include, for example, , maltodextrin, carrageenan, etc.; lubricants include, for example, magnesium stearate, stearic acid, sodium stearyl fumarate, etc.; chewable materials include, for example, dextrose, fructose dc, lactose (monohydrate, optionally in combination with aspartame or cellulose), etc.; suspending / gelling agents include, for example, carrageenan, sodium starch glycolate, xanthan gum, etc.; sweeteners include, for example, aspartame, dextrose, fructose dc, sorbitol, sucrose dc, etc.; wet granulating agents include, for example, calcium carbonate, maltodextrin, microcrystalline cellulose, etc.

[0098] Unless otherwise specified, "substantially pure" contemplates a composition containing 10% or less impurities, e.g., the composition contains less than about 9%, 7%, 5%, 3%, 1%, 0.5% impurities.

[0099] It will be understood that the term "comprise" or variations such as "comprises" or "comprising" means the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. Aspects and embodiments described herein as "comprising" will be understood to include "consisting of" and "consisting essentially of" embodiments.

[0100] When a composition is described as "consisting essentially of" recited components, the composition contains the explicitly recited components and may contain other components, such as trace impurities, that do not substantially affect the disease or condition being treated. However, the composition does not contain any other components other than the explicitly recited components that substantially affect the disease or condition being treated, or, if the composition contains additional components other than the recited components that substantially affect the disease or condition being treated, the composition does not contain the additional components in concentrations or amounts sufficient to substantially affect the disease or condition being treated. When a method is described as "consisting essentially of" recited steps, the method contains the recited steps and may contain other steps that do not substantially affect the disease or condition being treated, but the method does not contain any other steps other than the explicitly recited steps that substantially affect the disease or condition being treated.

[0101] As used herein, when a given structure exists in enantiomeric and / or diastereomeric forms, a "planar bond" indicates that all stereoisomers of the depicted structure may exist (e.g., compound 1 in Table 1 shown below). [ka]
