Description

Attorney Docket No.: INMD-221 / 01WO 315953-4549USES OF DPP1 INHIBITORSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 745,952, filed on January 16, 2025, the content of which is hereby incorporated by reference in its entirety for all purposes.BACKGROUND

[0002] Dipeptidyl peptidase 1 (DPP1), also known as cathepsin C, is a type of lysosome cysteine protease capable of removing the dipeptide from the amino terminal of protein substrates. The earliest discovery of DPP1 was by Gutman and Fruton in 1948 (J Biol Chem, 174, 851-858); subsequently, its earliest description in human cDNA occurred in 1995 (inmd-213FEBS Lett, 369, 326-330). DPP1 is the only member of the papain-like protease family that has a tetramer effect and is composed of four identical subunits. Each subunit is composed of an N-terminal fragment, a heavy chain and a light chain (J Biol Chem, 270, 21626-21631).

[0003] High levels of DPP1 are expressed by many tissues of the lungs, kidneys, liver and spleen (Biol. Chem. Hoppe Seyler 373: 367-373, 1992). As such it has the same role in activating serine protease in haematopoietic stem cells, and there is also relatively high expression of DPP1 in neutrophils, cytotoxic lymphocytes, natural killer cells, alveolar macrophages and mastocytes. The latest data has shown that, apart from being an important enzyme in lysosomal protein degradation, DPP1 also plays a role as a key enzyme in the activation of the following cell serine protease particles: cytotoxic T lymphocytes and natural killer cells (granzymes A and B; Proc. Nat. Acad. Sci. 96: 8627-8632, 1999), mastocytes (chymotrypsin and fibrinogenase; J Biol. Chem. 276: 18551-18556, 2001), and neutrophils (cathepsin G, elastinase and protease hydrolase 3; J Clin. Invest. 109: 363. 371, 2002). Once activated, these proteases can cause degradation of multiple extracellular matrix components, resulting in tissue damage and chronic inflammation. Due to DPP1 playing a key role in the activation of these proteases, it has become considered to be a type of effective therapeutic target (J Clin Invest, 2002, 109, 363-271; J Immunol, 2004, 173, 7277-7281).

[0004] In light of this, cathepsin C inhibitors exhibit potential for use in treatment in various inflammatory diseases. In view of the effect of DPP1 on certain pro-inflammatory serine proteases, clinical applications that suppress its activity and therefore suppress downstream serine protease activity may have favorable prospects. Currently, there are a number of related patent applications that give reports of synthesis of DPP1 inhibitors, including WO2023243601.Attorney Docket No.: INMD-221 / 01WO 315953-4549

[0005] Because DPP1 has been implicated in a number of disease states, and because no DPP1 inhibitors have been approved by a regulatory authority, there remains a need novel use of DPP1 inhibitors in treating various diseases and disorders.SUMMARY

[0087] In embodiments of any one of the methods disclosed herein, the disorder is cryptogenic fibrosing alveolitis, idiopathic interstitial pneumonia, fibrosis complicating anti-neoplastic therapy or fibrosis complicating chronic infection

[0088] In embodiments of any one of the methods disclosed herein, the disorder is non-cystic fibrosis bronchiectasis (NCFBE).

[0089] In embodiments of any one of the methods disclosed herein, the disorder is ronchiectasis associated with cystic fibrosis.

[0090] Cystic fibrosis (CF) is caused by abnormalities in the CF transmembrane conductance regulator protein, causing chronic lung infections (particularly with Pseudomonas aeruginosa) and excessive inflammation, and leading to bronchiectasis, declining lung function, respiratory insufficiency and quality of life. The inflammatory process is dominated by neutrophils that produce Neutrophil elastase (NE), as well as other destructive Neutrophil serine proteases (NSPs) including CatG and PR3, that directly act upon extracellular matrix proteins and play a role in the host response to inflammation and infection (Dittrich et al., Eur Respir J.2018;51(3)). The methods provided herein employ reversible inhibitors of DPP1. Without wishing to be bound by theory, it is thought that the compounds of Formula (I), (la), or (lb) administered via the methods provided herein have beneficial effects via inhibiting the activation of NSPs and decreasing inflammation, which in turn leads to a decrease in pulmonary exacerbations, a decrease in the rate of pulmonary exacerbations, and / or anAttorney Docket No.: INMD-221 / 01WO 315953-4549improvement in lung function (e.g., forced expiratory volume in 1 second [FEVi]) in CF subjects.

[0091] Bronchiectasis is considered a pathological endpoint that results from many disease processes and is a persistent or progressive condition characterized by dilated thick-walled bronchi. The symptoms vary from intermittent episodes of expectoration and infection localized to the region of the lung that is affected to persistent daily expectoration often of large volumes of purulent sputum. Bronchiectasis may be associated with other non-specific respiratory symptoms. The underlying pathological process of bronchiectasis, without wishing to be bound by theory, has been reported as damage to the airways which results from an event or series of events where inflammation is central to the process (Guideline for non-CF Bronchiectasis, Thorax, July 2010, V. 65(Suppl 1), incorporated by reference herein in its entirety for all purposes).

[0092] The methods provided herein employ reversible inhibitors of DPP1. Without wishing to be bound by theory, it is thought that the compounds of Formula (I), (la), or (lb) or Table 1, or a pharmaceutically acceptable salt, a stereoisomer or a deuterated from thereof administered via the methods provided herein have beneficial effects via decreasing inflammation and mucus hypersecretion, which in some embodiments, leads to a decrease in pulmonary exacerbations, a decrease in the rate of pulmonary exacerbations, and / or an improvement in lung function (cough, sputum production, and forced expiratory volume in 1 second [FEVi]) in bronchiectasis subjects. Without wishing to be bound by theory, it is thought that the methods provided herein modify bronchiectasis progression by reducing the accelerated rate of lung function decline or lung tissue destruction.

[0093] In embodiments of any one of the methods disclosed herein, the disorder is non-cystic fibrosis bronchiectasis (NCFBE) or bronchiectasis associated with CF, and the treating comprises improving the lung function of the subject, as compared to the lung function of the subject prior to treatment. In embodiments, improving lung function of the subject comprises increasing the subject’s forced expiratory volume in 1 second (FEVi), increasing the subject’s forced vital capacity (FVC), increasing the subject’s peak expiratory flow rate (PEFR), or increasing the subject’s forced expiratory flow between 25% and 75% of FVC (FEF (25-75%)), as compared to the respective value for the subject prior to treatment. In embodiments, the lung function is measured by spirometry.

[0094] In embodiments of any one of the methods disclosed herein, the disorder is non-cystic fibrosis bronchiectasis (NCFBE) or bronchiectasis associated with CF, and the treatingAttorney Docket No.: INMD-221 / 01WO 315953-4549comprises decreasing the rate of pulmonary exacerbation, as compared to the rate of pulmonary exacerbation of the subject prior to treatment.

[0095] A pulmonary exacerbation, in one embodiment, is characterized by three or more of the following symptoms exhibited for at least 48 hours by the subject : (1) increased cough; (2) increased sputum volume or change in sputum consistency; (3) increased sputum purulence; (4) increased breathlessness and / or decreased exercise tolerance; (5) fatigue and / or malaise; (6) hemoptysis. In a further embodiment, the three or more symptoms result in a physician’s decision to prescribe an antibiotic(s) to the subject exhibiting the symptoms.

[0096] In embodiments of any one of the methods disclosed herein, the treating comprises increasing the time to first pulmonary exacerbation, as compared to an untreated subject. In embodiments, the pulmonary exacerbation is characterized by three or more of the following symptoms exhibited for at least 48 hours by the subject : (1) increased cough; (2) increased sputum volume or change in sputum consistency; (3) increased sputum purulence; (4) increased breathlessness and / or decreased exercise tolerance; (5) fatigue and / or malaise; (6) hemoptysis.

[0097] In one embodiment, the treatment methods provided herein comprise improving the lung function of the subject during the administration period, as compared to the lung function of the subject prior to the administration period. In a further embodiment, the compound is administered orally, once daily. The improvement in lung function in one embodiment, is measured by spirometry.

[0098] Improving the lung function of the subject , in one embodiment, comprises increasing the subject’s forced expiratory volume in 1 second (FEVi), increasing the subject’s forced vital capacity (FVC), increasing the subject’s peak expiratory flow rate (PEFR), or increasing the subject’s forced expiratory flow between 25% and 75% of FVC (FEF (25-75%)), as compared to the respective value prior to the administration period. Increasing, in one embodiment, is by about 5%, by about 10%, by about 15%, by about 20%, by about 25%, by about 30%, by about 35%, by about 40%, by about 45% or by about 50% of the respective value.
