[Background technology]
[0004] Certain compounds of formula (I) are disclosed in PCT / EP2021 / 069292 as modulators of CFTR and are believed to be useful in the treatment of CFTR-related diseases and disorders, in particular cystic fibrosis, or other CFTR-related diseases and disorders selected from: - chronic bronchitis; sinusitis; constipation; pancreatitis; pancreatic insufficiency; male infertility caused by congenital bilateral absence of the vas deferens (CBAVD); mild lung disease; allergic bronchopulmonary aspergillosis (ABPA); liver disease; coagulation-fibrinolysis deficiencies such as protein C deficiency; and diabetes; - asthma; COPD; smoking-induced COPD; and dry eye disease; and - idiopathic pancreatitis; hereditary emphysema; hereditary hemochromatosis; especially I-cell disease; lysosomal storage disorders such as pseudo-Hurler; mucopolysaccharidoses; Sandhoff / Tay-Sachs disease; osteogenesis imperfecta; Fabry disease; Sjogren's disease; osteoporosis; osteopenia; bone healing and growth (including bone repair, bone regeneration, decreased bone resorption, and increased bone deposition); chlorhydria such as congenital myotonia (Thomson and Becker forms). chloride channelopathies; Bartter's syndrome type 3; epilepsy; lysosomal storage diseases; primary ciliary dyskinesia (PCD) - a term for genetic disorders of ciliary structure and / or function (including PCD with situs inversus, also known as Kartagener syndrome, PCD without situs inversus, and ciliary aplasia); generalized epilepsy with febrile seizures plus (GEFS+); generalized epilepsy with febrile and afebrile seizures; myotonia; paramyotonia congenita; potassium-aggravated myotonia; hyperkalemic periodic paralysis; long QT syndrome (LQTS); LQTS / Brugada syndrome; autosomal dominant LQTS with hearing loss; autosomal recessive LQTS; LQTS with atypical features dysmorphic features); congenital and acquired LQTS; dilated cardiomyopathy; autosomal dominant LQTS; osteopetrosis; and Bartter syndrome type 3.
[0005] Cystic fibrosis (CF; mucoviscidosis, also known as fibrocystic disease of pancreas or pancreatic fibrosis) is an autosomal recessive genetic disease caused by dysfunction of an epithelial chloride / bicarbonate channel called the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). CFTR dysfunction causes dysregulation of chloride, bicarbonate, and water transport at the surface of secretory epithelia, leading to the accumulation of thick mucus in organs including the lungs, pancreas, liver, and intestine, resulting in multiple organ failure. Today, the most debilitating effects of CF are observed in the lungs, where—due to abnormal hydration of airway surface fluid, mucus plugging, impaired mucociliary clearance, chronic inflammation, and infection—the lungs eventually lose their function and cause death from respiratory failure (Elborn, 2016). Human CFTR is a multidomain protein with 1,480 amino acids. Many different mutations causing CFTR dysfunction have been found in CF patients, including loss of functional CFTR protein (class I mutations), CFTR trafficking defects (class II mutations), CFTR regulation defects (also known as gating defects; class III mutations), CFTR conductance defects (class IV mutations), reduced CFTR protein due to splicing defects (class V mutations) or reduced CFTR stability (class VI mutations), and loss of CFTR protein due to mRNA destabilization (class VII mutations) (de Boeck, Acta Paediatr. 2020, 109(5):893-895).The CFTR2 database (http: / / cftr2.org; data as of 22.08.2022) currently contains information on 401 disease-causing mutations. The most frequent disease-causing mutation by far is a deletion of phenylalanine at position 508 (F508del; allele frequency 0.697 in the CFTR2 database), which causes channel misfolding during synthesis in the endoplasmic reticulum, degradation of the misfolded protein, and consequently, significantly reduced transport to the cell surface (class II mutation). The remaining F508del-CFTR that traffics to the cell surface is functional, but less functional than wild-type CFTR; thus, F508del-CFTR also contains a gating defect (Dalemans, 1991). Approximately 40% of all CF patients are homozygous for the F508del mutation, while another ~40% of patients are heterozygous for the F508del mutation and have another disease-causing mutation in class I, II, III, IV, V, VI, or VII. Such disease-causing mutations are quite rare, with class III G551D mutations (allele frequency 0.0210) and class I G542X mutations (allele frequency 0.0254) and class II The N1303K mutation (allele frequency 0.0158) is the next most common.
[0006] Currently, CF is treated with a wide range of medications for various organ symptoms and disorders. Intestinal and pancreatic disorders are treated, once diagnosed, with the addition of pancreatic digestive enzymes to the diet. Pulmonary symptoms are primarily treated with inhaled hypertonic saline, mucolytics, anti-inflammatory agents, bronchodilators, and antibiotics (Elborn, 2016).
[0007] In addition to symptomatic treatments, CFTR modulators have been developed and approved for patients with specific CFTR mutations. These compounds either directly improve CFTR folding and CFTR trafficking to the cell surface (CFTR correctors) or improve CFTR function at the cell surface (CFTR potentiators). Other types of modulators, such as compounds that increase (mutated) CFTR mRNA levels (CFTR amplifiers) and compounds that increase the plasma membrane stability of mutated CFTR (CFTR stabilizers), such as the nucleotide-binding domain 1 (NBD1) stabilizer SION-638 (currently in Phase 1) and its follow-on molecule, NBD1-A, are still in the exploratory stage (G. Hurlbut, oral presentation at the North American Cystic Fibrosis Conference 2022). CFTR modulators can also enhance the function of non-mutated (i.e., wild-type) CFTR and are therefore being studied in disorders where increasing wild-type CFTR function may have beneficial effects, such as chronic bronchitis / COPD / bronchiectasis (Le Grand, J Med Chem. 2021, 64(11):7241-7260. Patel, Eur Respir Rev. 2020, 29(156):190068) and dry eye disease (Flores, FASEB J. 2016, 30(5):1789-1797), as well as in non-CF disorders such as acute respiratory distress syndrome (ARDS) (Erfinanda L, Sci Transl Med. 2022, 14(674):eabg8577).
[0008] CFTR modulators and combinations thereof can be discovered and optimized by assessing their ability to promote mutant CFTR trafficking and function in in vitro cultured recombinant and primary cell lines, with activity in such systems predictive of activity in CF patients.
[0009] WO2019 / 161078 discloses macrocycles as modulators of cystic fibrosis, generally 15-membered macrocycles having a (pyridine-carbonyl)-sulfamoyl moiety linked to an additional aromatic group. Further macrocycles are disclosed in WO2022 / 109573 (macrocycles having a 1,3,4-oxadiazole ring), WO2022 / 076625, WO2022 / 076626, WO2022 / 076624, WO2022 / 076621, WO2022 / 076620, WO2022 / 076618, WO2021 / 030556, and WO2021 / 030555. Macrocyclic tetrapeptides (12 or 13 members), such as the compound Apicidin (CAS: 183506-66-3), have been proposed as potential agents for the treatment of CF (Hutt DM et al., ACS Med Chem Lett. 2011;2(9):703-707. doi:10.1021 / ml200136e). WO2020 / 128925 discloses macrocyclic compounds capable of modulating the activity of CFTR, the macrocyclic compounds having an optionally substituted bivalent N-(pyridin-2-yl)pyridinyl-sulfonamide moiety. Other macrocyclic compounds have been described to stabilize the chloride channel CFTR (Stevers LM et al., Nature C Communications 2022, 13:3586). Non-macrocyclic CFTR correctors and / or potentiators of CFTR are disclosed, for example, in WO2011 / 119984, WO2014 / 015841, WO2007 / 134279, WO2010 / 019239, WO2011 / 019413, WO2012 / 027731, WO2013 / 130669, WO2014 / 078842 and WO2018 / 227049, WO2010 / 037066, WO2011 / 127241, WO2013 / 112804, WO2014 / 071122 and WO2020 / 128768.Furthermore, specific macrocyclic compounds in which an unsubstituted phenylene group is a part of the macrocyclic compound in contrast to the 8- to 10-membered bicyclic heteroarylene of the compound of formula (I) of the present invention can be found as screening compounds (CAS registration numbers: CAS-2213100-89-9, CAS-2213100-96-8, CAS-2213100-99-1, CAS-2213101-02-9, CAS-2213101-04-1, CAS-2213101-06-3, CAS-2213101-08-5, CAS-2213101-09-6, CAS-2213101-10-7, CAS-2213101-11-1, CAS-2213101-12-1, CAS-2213101-13-2, CAS-2213101-14-3, CAS-2213101-15-4, CAS-2213101-16-5, CAS-2213101-17-6, CAS-2213101-18-7, CAS-2213101-19-8, CAS-2213101-20-1, CAS-2213101-21-1, CAS-2213101-22-1, CAS-2213101-23-1, CAS-2213101-24-1, CAS-2213101-25-2, CAS-2213101-26-3, CAS-2213101-27-4, CAS-2213101-28-5, CAS-2213101-29- 101-09-6, CAS-2213101-19-8, CAS-2213101-24-5, CAS-2215788-95-5, CAS-2215788-98-8, CAS-2215789-01-6, CAS-2215789-02-7, CAS- 2215789-09-4, CAS-2215789-15-2, CAS-2215789-20-9, CAS-2215789-24-3, CAS-2215789-35-6, CAS-2215789-37-8, CAS-2215946-94-2, CAS-2215947-04-7, CAS-2215947-13-8, CAS-2215947-24-1, CAS-2215947-34-3, CAS-2215947-44-5, CAS-2215947-51-4, CAS-2215947-6 4-9, CAS-2215947-68-3, CAS-2215947-78-5, CAS-2215947-91-2, CAS-2215954-57-5, CAS-2216342-34-4, CAS-2216342-78-6, CAS-22163 42-86-6, CAS-2216343-03-0, CAS-2216343-09-6, CAS-2216343-14-3, CAS-2216343-18-7, CAS-2216343-24-5, CAS-2216343-32-5, CAS-2 216343-38-1, CAS-2216343-45-0, CAS-2216343-53-0, CAS-2216343-59-6, CAS-2216343-64-3, CAS-2216343-74-5, CAS-2216343-76-7).
[0010] CFTR modulators can be further subdivided into CFTR correctors and CFTR potentiators. CFTR correctors improve CFTR folding and cell surface trafficking, particularly for CFTR with class II (folding and trafficking) mutations, thereby increasing cell surface expression of CFTR. CFTR potentiators increase the onset probability of cell-surface CFTR, particularly for CFTR with gating defects, including corrector-rescued class II mutants, and can thus activate CFTR additively / synergistically with CFTR correctors. Thus, potentiators and correctors are used in combination in clinical settings to treat patients with CFTR class II mutations. Many CFTR correctors have been described in literature and patents. Some of these correctors, such as VX-809 (lumacaftor), VX-661 (tezacaftor), ABBV-2222 (galicaftor), VX-445 (elexacaftor), VX-659 (bamocaftor), VX-440 (olacaftor), VX-121 (vanzacaftor), the ABBV-C2 correctors ABBV-119 and ABBV-567, as well as PTI-801, have been used in clinical trials in CF patients, alone and / or in combination with other CFTR modulators. Similarly, many potentiators have been described in the literature and in patents. Some of these potentiators, such as VX-770 (ivacaftor), VX- 561 (deutivacaftor), GLPG-1837, GLPG-2451, ABBV-3067 (navocaftor), and QBW-251 (icenticaftor), alone and / or in combination with other CFTR modulators, are being used in clinical trials in patients with CF.
[0011] CFTR correctors can be further subdivided with regard to their mechanisms: it is well established that correctors that exhibit additive or synergistic behavior must have distinct, i.e., complementary, mechanisms of action, likely resulting from different binding sites on the CFTR protein. Conversely, correctors that exhibit competitive behavior are likely to share the same CFTR binding site (Okiyoneda, 2013; Veit, 2018; Veit, 2020; Fiedorczuk 2022; Marchesin 2023). Thus, the structurally related correctors VX-809 (lumacaftor), VX-661 (tezacaftor), and ABBV-2222 (galicaftor) are classified as type I correctors, corrector 4a and related compounds are classified as type II correctors, while VX-445 (elexacaftor) is classified as a type III corrector, as are the structurally related correctors VX-440 (olacaftor), VX-659 (vamocaftor), and VX-121 (banzacaftor). The ABBV-C2 corrector, ABBV-119, and ABBV-567 are likely type III correctors. PTI-801 is likely another type III corrector. Due to the additive nature of their effects, correctors with different mechanisms are often combined in clinical settings to achieve greater correction efficacy with potentiators.
[0012] VX-770 (ivacaftor, KALYDECO, N-(2,4-di-tert-butyl-5-hydroxyphenyl)-1,4-dihydro-4-oxoquinoline-3-carboxamide, CAS 873054-44-5, e.g., WO2006 / 002421, WO2011 / 072241, WO2007 / 079139, WO2007 / 134279, WO2010 / 019239, WO2013 / 130669) is a CFTR potentiator and has been reported clinically and / or in vivo. Based on in vitro assay data, VX-770 is the first CFTR modulator approved (US and EU: initial approval in 2012) for the treatment of CF patients aged 4 months and older who have a single mutation in the CFTR gene that responds to KALYDEKO. The current USPI for VX-770 (as of December 2020) lists 97 eligible CFTR mutations. VX-770 is also part of ORKAMBI (a combination of VX-809 and VX-770), SYMDEKO / SYMKEVI (a combination of VX-661 and VX-770), and TRIKAFTA / KAFTRIO (a combination of VX-661, VX-445, and VX-770), which are described below.
[0013] The efficacy of KALYDECO in CF patients with the G551D mutation in the CFTR gene was evaluated in two Phase III clinical trials involving 213 CF patients. Study 1 (NCT00909532) evaluated patients aged 12 years and older, while Study 2 (NCT00909727) evaluated patients aged 6 to 11 years. Patients were randomized (1:1) and were randomly assigned to receive prescribed CF medications (e.g., tobramycin, dornase alfa). alfa) and given KALYDECO or placebo with a fat-containing meal for 48 weeks. The primary endpoint was improvement in lung function, measured by the mean absolute change from baseline in percent predicted pre-dose FEV1 over 24 weeks of treatment. FEV1 stands for "forced expiratory volume in 1 second," and is commonly used as the primary endpoint for assessing lung function in clinical trials for CF. Both studies In this study, treatment with KALYDECO resulted in a significant absolute change of at least 10% in percent-predicted FEV1 (ppFEV1) compared with placebo. Several secondary endpoints, including risk of pulmonary exacerbation (Study 1: relative risk reduction of 0.4 vs. placebo), body weight (+approximately 2 kg vs. placebo), and the pharmacodynamic biomarker sweat chloride (-approximately 50 mM vs. placebo), were also favorably affected by KALYDECO after 48 weeks of treatment. Another small Phase 3 study tested KALYDECO in CF patients aged 6 years and older with rare mutations predictive of response, using change from baseline in absolute ppFEV1 as the primary endpoint. Furthermore, KALYDECO was evaluated in CF patients aged 4 months to 5 years without evaluating efficacy by FEV1 measurement; however, KALYDECO exposure and sweat chloride reductions were similar to those seen in studies with older patients. The recommended dose of KALYDECO for adults and pediatric patients 6 years of age and older is one 150 mg tablet taken orally every 12 hours (bid). The recommended dose of KALYDECO (oral granules) for patients 4 months to less than 6 years of age is based on body weight: 25 mg bid for patients 4-6 months of age (if weighing >5 kg); 25 mg bid for patients 6 months to less than 6 years of age (if weighing 5-7 kg), 50 mg bid for patients 7-14 kg, and 75 mg bid for patients 6 months to less than 6 years of age. bid (for patients weighing 14-25 kg). The FDA recommends that for patients 6 months of age and older with moderate hepatic impairment (Child-Pugh class B), the KALYDECO dosage be reduced to one tablet or one packet of oral granules once daily. For patients 6 months of age and older with severe hepatic impairment (Child-Pugh class C), KALYDECO should be used cautiously at a dose of one tablet or one packet of oral granules once daily or less frequently. Use is not recommended for patients under 6 months of age with hepatic impairment. KALYDECO is available as a light blue, film-coated capsule tablet for oral administration containing 150 mg of ivacaftor. Each KALYDECO tablet contains the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, hypromellose acetate succinate, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate. The tablet film coat contains carnauba wax, FD&C Blue #2, PEG 3350, polyvinyl alcohol, talc, and titanium dioxide. The printing ink contains ammonium hydroxide, iron oxide black, propylene glycol, and shellac.
[0014] KALYDECO is also available as white to off-white oral granules (sweetened but unflavored) packaged in unit dose packets containing 25 mg, 50 mg, or 75 mg of ivacaflut. Each unit dose packet of KALYDECO oral granules additionally contains the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, hypromellose acetate succinate, lactose monohydrate, magnesium stearate, mannitol, sucralose, and sodium lauryl sulfate.
[0015] The overall safety profile of KALYDECO is based on pooled data from three placebo-controlled clinical trials (NCT00909532, NCT00909727, NCT00953706) conducted in 353 CF patients aged 6 years and older who had the G551D mutation in the CFTR gene or were homozygous for the F508del mutation. 221 patients received KALYDECO and 132 patients received placebo for 16 to 48 weeks. Serious adverse reactions that occurred more frequently in KALYDECO-treated patients, regardless of whether they were considered drug-related by the investigator, included abdominal pain, elevated liver enzymes, and hypoglycemia. Transaminase elevations have been reported in CF patients receiving KALYDECO. The FDA recommends that ALT and AST be assessed before initiating KALYDECO treatment, every 3 months during the first year of treatment, and annually thereafter. Treatment should be discontinued in patients with ALT or AST levels greater than 5 times the upper limit of normal (ULN). After the transaminase elevations resolved, the FDA We recommend considering the benefits and risks of restarting KALYDECO. Non-congenital lens opacities / cataracts have been reported in pediatric patients treated with KALYDECO. FDA recommends baseline and follow-up examinations for pediatric patients initiating KALYDECO treatment.
[0016] VX-809 (lumacaftor, 3-[6-({[1-(2,2-difluoro-1,3-benzodioxol-5-yl)cyclopropyl]carbonyl}amino)-3-methylpyridin-2-yl]benzoic acid, CAS 936727-05-8, e.g., WO2007 / 056341, WO2009 / 073757, WO2009 / 076141, WO2010 / 037066, WO2011 / 127241) is a Type I As part of ORKAMBI, a combination product with the CFTR corrector and CFTR potentiator lumacaftor, ivacaftor, it was approved in the US (2014) and EU (2015) for the treatment of patients aged 2 years and older with cystic fibrosis (CF) who are homozygous for the F508del mutation in the CFTR gene.
[0017] The efficacy of ORKAMBI was evaluated in CF patients homozygous for the F508del mutation in two Phase 3 clinical trials (NCT01807923, NCT01807949) involving a total of 1,108 patients aged 12 years or older. Of these, 369 patients received ORKAMBI (lumacaftor 400 mg / ivacaftor 250 mg, bid) for 24 weeks in addition to their prescribed CF medications (e.g., bronchodilators, inhaled antibiotics, dornase alfa, and hypertonic saline). The primary efficacy endpoint was change in lung function, as measured by absolute change from baseline in ppFEV1 at week 24. ORKAMBI treatment resulted in statistically significant increases of 2.6% and 3.0% in absolute ppFEV1 compared with placebo treatment. The secondary endpoint of risk of pulmonary exacerbations was also favorable with ORKAMBI (relative risk reduction of 0.3-0.4 vs. placebo). A small, open-label, Phase 3 study tested ORKAMBI in CF patients aged 6 to 11 years who were homozygous for the F508del mutation, measuring sweat chloride concentration as a marker of CFTR function. The mean absolute change from baseline in sweat chloride was -20.4 mM at Day 15 and -24.8 mM at Week 24. After a two-week washout period, mean absolute sweat chloride concentrations increased by 21.3 mM. Similarly, in CF patients aged 2 to 5 years who were homozygous for F508del-CFTR, the mean absolute change from baseline in sweat chloride was -31.7 mM at Week 24, followed by an increase of 33 mM after a two-week washout period. These data demonstrate improvement in CFTR function. The efficacy of ORKAMBI in children 2 to 11 years of age was extrapolated from efficacy in patients 12 years of age and older who are homozygous for the F508del mutation, and is supported by population pharmacokinetic analyses showing similar drug exposure levels in patients 12 years of age and older and children 2 to 11 years of age. The recommended dose of ORKAMBI for adults and pediatric patients 12 years of age and older is two tablets (each tablet contains 200 mg lumacaftor / 125 mg ivacaftor) taken orally every 12 hours, for a total of 800 mg lumacaftor / 500 mg ivacaftor daily.The recommended dose of ORKAMBI for patients 6 to 11 years of age is two tablets (each containing 100 mg lumacaftor / 125 mg ivacaftor) taken orally bid, for a total of 400 mg lumacaftor / 500 mg ivacaftor per day. For patients 2 to 5 years of age, the dose of ORKAMBI depends on body weight. For children over 14 kg, one granule packet (containing 150 mg lumacaftor / 188 mg ivacaftor) is recommended for oral administration bid. For children under 14 kg, one granule packet (containing 100 mg lumacaftor / 125 mg ivacaftor) is recommended for oral administration bid. The FDA recommends that ORKAMBI be used in children with moderate hepatic impairment (Child-related liver damage). The recommended dosage for ORKAMBI is two tablets in the morning and one tablet in the evening for patients 6 years of age and older with hepatic impairment (Child-Pugh class B), and one packet of granules daily for patients 2 to 5 years of age with moderate hepatic impairment (Child-Pugh class C). In patients with severe hepatic impairment (Child-Pugh class C), ORKAMBI should be used with caution, at the maximum dose, with one tablet in the morning and one tablet in the evening or less frequently, or one packet of oral granules once daily or less frequently. ORKAMBI is available as pink, oval, film-coated fixed-dose tablets containing 100 mg lumacaftor and 125 mg ivacaftor, or 200 mg lumacaftor and 125 mg ivacaftor. Additionally, the following inactive ingredients are present: cellulose, microcrystalline; croscarmellose sodium; hypromellose acetate succinate; magnesium stearate; povidone; and sodium lauryl sulfate. The tablet film coat contains carmine, FD&C Blue No. 1, FD&C Blue No. 2, polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide. The printing ink contains ammonium hydroxide, triferric oxide, propylene glycol, and shellac. ORKAMBI is also available as oral granules in unit-dose packets containing 100 mg lumacaftor / 125 mg ivacaftor or 150 mg lumacaftor / 188 mg ivacaftor per packet. Additionally, the following inactive ingredients are present: cellulose, microcrystalline; croscarmellose sodium; hypromellose acetate succinate; povidone; and sodium lauryl sulfate. The overall safety profile of ORKAMBI is based on pooled data from 1,108 CF patients aged 12 years and older who are homozygous for the F508del mutation and received at least one dose of study drug in two double-blind, placebo-controlled Phase 3 clinical trials, both involving 24 weeks of treatment. 369 patients received ORKAMBI bid and 370 patients received placebo. Serious adverse reactions that occurred more frequently in ORKAMBI-treated patients, regardless of whether they were considered drug-related by the investigator, were pneumonia, hemoptysis, cough, increased blood creatine phosphokinase, and increased transaminases. These occurred in 1% or less of patients.Elevated transaminases (ALT / AST) have been observed in some cases in association with elevated bilirubin. The FDA recommends measuring serum transaminases and bilirubin before initiating ORKAMBI, every 3 months during the first year of treatment, and annually thereafter. Treatment should be interrupted in patients with ALT or AST >5x the upper limit of normal (ULN), or in patients with ALT or AST >3x ULN and bilirubin >2x ULN. After resolution, the FDA recommends considering the benefits and risks of resuming ORKAMBI. Furthermore, respiratory side effects (chest discomfort, dyspnea, and breathing abnormalities) are more common at the time of ORKAMBI initiation and in patients with ppFEV1 <40%, and additional monitoring is recommended during treatment initiation. Elevated blood pressure has also been observed in some patients, and the FDA recommends periodic monitoring of blood pressure in all patients. Noncongenital lens opacities / cataracts have been reported in pediatric patients treated with ORKAMBI. The FDA recommends baseline and follow-up testing for pediatric patients initiating ORKAMBI treatment.
[0018] VX-661 (tezacaftor, 1-(2,2-difluoro-2H-1,3-benzodioxol-5-yl)-N-{1-[(2R)-2,3-dihydroxypropyl]-6-fluoro-2-(1-hydroxy-2-methylpropan-2-yl)-1Hindol-5-yl}cyclopropane-1-carboxamide), CAS 1152311-62-0 (e.g., WO2007 / 117715, WO2011 / 119984, WO2014 / 014841) is a type I CFTR corrector approved in the US (2018) as part of SYMDEKO and in the EU (2018) as part of SYMKEVI. SYMDEKO / SYMKEVI is homozygous for the F508del mutation in the CFTR gene. It is a combination product of tezacaftor and the CFTR potentiator ivacaftor for the treatment of cystic fibrosis (CF) in patients 6 years of age and older who have at least one mutation in the CFTR gene that is responsive to tezacaftor / ivacaftor based on in vitro data and / or clinical evidence. The current SYMDEKO USPI (June 2022) lists 154 active CFTR mutations.
[0019] The efficacy of SYMDEKO in CF patients aged 12 years and older was evaluated in three double-blind, placebo-controlled trials (Studies 1, 2, and 3). In all trials, patients continued their standard-of-care CF medications (e.g., bronchodilators, inhaled antibiotics, dornase alfa, and hypertonic saline). Study 1 (NCT02347657) evaluated 504 patients homozygous for the F508del-CFTR mutation. Patients were randomized 1:1 to receive SYMDEKO or placebo with a fat-containing diet. The primary efficacy outcome was improvement in lung function as measured by the mean absolute change from baseline in ppFEV1 over 24 weeks of treatment. Treatment with SYMDEKO resulted in a significant 4% absolute change in ppFEV1 compared with placebo. Several secondary endpoints also showed favorable changes with SYMDEKO after 24 weeks of treatment, including risk of pulmonary exacerbations (relative risk reduction of 0.35 vs. placebo), absolute change from baseline to week 24 in CFQ-R Respiratory Domain Score (a measure of respiratory symptoms relevant to CF patients, such as cough, sputum, and dyspnea: +5.1), and absolute change from baseline in sweat chloride to week 24 (-10.1 mM vs. placebo).
[0020] Study 2 (NCT02392234), a crossover study, evaluated 244 patients (146 patients with a splice mutation and 98 patients with a missense mutation as the second allele) who were heterozygous for the F508del mutation and a second mutation predicted to be responsive to tezacaftor / ivacaftor. The primary efficacy outcome measure was improvement in lung function as measured by the mean absolute change from baseline in ppFEV1 averaged over weeks 4 and 8 of treatment. Treatment with SYMDEKO resulted in a significant 6.8% absolute change in ppFEV1 compared with placebo. SYMDEKO also significantly improved several secondary endpoints, including absolute change from baseline in CFQ-R Respiratory Domain Score (+11.1 vs. placebo) and sweat chloride (-9.5 mM), a biomarker of CFTR function. Study 3 (NCT02516410) evaluated SYMDEKO in 168 patients heterozygous for the F508del mutation and a second mutation not predicted to respond to tezacaftor / ivacaftor. No significant changes from baseline in absolute ppFEV1 were observed in the SYMDEKO group by week 12 when compared with the placebo group.
[0021] The efficacy of SYMDEKO in patients 6 to <12 years of age was extrapolated from patients 12 years of age and older, and this is supported by population pharmacokinetic analyses showing similar exposure levels of tezacaftor and ivacaftor in patients 6 to <12 years of age (Study 4; (NCT02953314), an open-label study in 70 patients) and patients 12 years of age and older (Studies 1 and 2). Additionally, in Study 4, a change in sweat chloride of -14.5 mM from baseline to Week 24 was observed, indicating improved CFTR function.
[0022] The recommended dose of SYMDEKO for patients 12 years of age and older and pediatric patients 6 years of age and older is one tablet (containing 100 mg tezacaftor / 150 mg ivacaftor) in the morning and one tablet (containing 150 mg ivacaftor) in the evening, for a total of 100 mg tezacaftor / 300 mg ivacaftor per day, if weighing 30 kg or more. The recommended dose of SYMDEKO for patients 6 to 11 years of age is one tablet (containing 50 mg tezacaftor / 75 mg ivacaftor) in the morning and one tablet (containing 75 mg ivacaftor) in the evening, for a total of 100 mg tezacaftor / 300 mg ivacaftor per day, if weighing less than 30 kg. The SYMDEKO dosage is 50 mg tezacaftor / 150 mg ivacaftor. The FDA recommends that patients with moderate hepatic impairment (Child-Pugh class B) have their SYMDEKO dose reduced to one morning tablet and the evening ivacaftor dose omitted. In patients with severe hepatic impairment (Child-Pugh class C), SYMDEKO should be used with caution, with a maximum dose of one morning tablet.
[0023] SYMDEKO is available as a white capsule-type tezacaftor / ivacaftor fixed-dose combination tablet packaged with a light blue capsule-type ivacaftor tablet. It is available in 50 mg tezacaftor / 75 mg ivacaftor + 75 mg ivacaftor and 100 mg tezacaftor / 150 mg ivacaftor + 150 mg ivacaftor packages. The following inactive ingredients are present in the tezacaftor / ivacaftor combination tablet: croscarmellose sodium, hypromellose, hypromellose acetate succinate, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate. The tablet film coat contains HPMC / hypromellose 2910, hydroxypropyl cellulose, talc, and titanium dioxide. Ivacaftor tablets contain the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, hypromellose acetate succinate, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate. The tablet film coat contains carnauba wax, FD&C Blue No. 2, PEG 3350, polyvinyl alcohol, talc, and titanium dioxide. The printing ink contains ammonium hydroxide, iron oxide, propylene glycol, and shellac.
[0024] The overall safety profile of SYMDEKO is based on data from 1,001 CF patients in three double-blind, placebo-controlled clinical trials: two 12-week and 24-week parallel-group studies (NCT02347657, NCT02516410) and one 8-week crossover study (NCT02392234). Eligible patients were also eligible to participate in an open-label extension safety study (up to 96 weeks of SYMDEKO). A total of 496 CF patients aged 12 years and older received at least one dose of SYMDEKO in the three placebo-controlled trials. Serious adverse reactions that occurred more frequently in SYMDEKO-treated patients compared with placebo, regardless of whether they were considered drug-related by the investigator, included distal intestinal obstruction syndrome (3 (0.6%) SYMDEKO-treated patients vs. 0 placebo-treated patients). Transaminase elevations (ALT / AST) were observed in SYMDEKO-treated patients. The FDA recommends measuring serum transaminases before starting SYMDEKO, every 3 months during the first year of treatment, and annually thereafter. Treatment should be interrupted in patients with ALT or AST >5x the upper limit of normal (ULN), or in patients with ALT or AST >3x ULN and bilirubin >2x ULN. After resolution, the FDA recommends considering the benefits and risks of restarting SYMDEKO. Non-congenital lens opacities / cataracts have been reported in pediatric patients treated with SYMDEKO. The FDA recommends baseline and follow-up testing for pediatric patients initiating SYMDEKO treatment.
[0025] VX-445 (elexacaftor, N-(1,3-dimethyl-1H-pyrazole-4-sulfonyl)-6-[3-(3,3,3-trifluoro-2,2-dimethylpropoxy)-1H-pyrazol-1-yl]-2-[(4S)-2,2,4-trimethylpyridin-1-yl]pyridine-3-carboxamide 2,2-dimethylpropoxy)-1H-pyrazol-1-yl]-2-[(4S)-2,2,4-trimethylpyrrolidin-1-yl]pyridine-3-carboxamide), CAS2216712-66-0, e.g., WO2016 / 057572, WO2018 / 107100, WO2019 / 152940), is a type III CFTR corrector and part of TRIKAFTA. TRIKAFTA / KAFTRIO was approved in the US as a combination product of elexacaftor and benzocaine-3000 (as of 2019) and in the EU as part of KAFTRIO in 2020. TRIKAFTA / KAFTRIO is a combination product of elexacaftor and benzocaine-3000 (as of 2020) for the treatment of cystic fibrosis (CF) in patients 6 years of age and older with at least one F508del mutation in the CFTR gene or a CFTR gene mutation that is responsive based on in vitro data. It is a combination product of the CFTR corrector tezacaftor and the CFTR potentiator ivacaftor. The current TRIKAFTA USPI (October 2021) lists 178 valid CFTR mutations.
[0026] The efficacy of TRIKAFTA in patients with CF aged 12 years and older was evaluated in two double-blind, placebo-controlled studies (Studies 1 and 2). Patients discontinued their previous CFTR modulator therapy but continued other standard-of-care CF medications (e.g., bronchodilators, inhaled antibiotics, dornase alfa, and hypertonic saline). Study 1 (NCT03525444) evaluated 403 patients (200 TRIKAFTA, 203 placebo). These patients had an F508del mutation in one allele and a mutation in the second allele resulting in a CFTR protein that was either null or unresponsive to ivacaftor and tezacaftor / ivacaftor. The primary efficacy outcome measure was improvement in lung function, as measured by the mean absolute change from baseline in ppFEV1 over 4 weeks of treatment at an interim analysis point. The treatment difference between TRIKAFTA and placebo was 13.8%. Risk of pulmonary exacerbation (relative risk reduction of 0.63 vs. placebo), absolute change from baseline in CFQ-R Respiratory Domain Score (+20.2 vs. placebo), and absolute change from baseline in body mass index (BMI) (+1.04 kg / m vs. placebo) 2 TRIKAFTA also demonstrated favorable changes in key secondary endpoints measured at 24 weeks of treatment, including absolute change from baseline in sweat chloride (-41.8 mM vs. placebo) and sweat chloride (-41.8 mM vs. placebo).
[0027] Study 2 (NCT03525548) evaluated 107 CF patients aged 12 years or older who were homozygous for the F508del mutation. After a 4-week open-label run-in period with tezacaftor / ivacaftor, patients were randomized to TRIKAFTA or continued tezacaftor / ivacaftor for 4 weeks. The primary endpoint was the mean absolute change from baseline in ppFEV1 at week 4 of the double-blind treatment period. Treatment with TRIKAFTA resulted in a statistically significant 10.0% improvement in ppFEV1 compared with tezacaftor / ivacaftor. Key secondary endpoints at week 4, including absolute change from baseline in CFQ-R Respiratory Domain Score (+17.4) and sweat chloride, a CFTR functional biomarker (-45.1 mM), also showed favorable changes with TRIKAFTA compared with tezacaftor / ivacaftor.
[0028] Study 3 (NCT03691779) was an open-label study evaluating TRIKAFTA in 66 children 6 to <12 years of age who were homozygous for the F508del mutation or heterozygous for the F508del mutation and had a mutation on the second allele that resulted in a CFTR protein that was either null or unresponsive to ivacaftor and tezacaftor / ivacaftor. The mean absolute change from baseline in sweat chloride to week 24 was -60.9 mmol / L. The efficacy of TRIKAFTA in patients 6 to <12 years of age was extrapolated from patients 12 years of age and older, and this is supported by population pharmacokinetic analyses showing that exposure levels of elexacaftor, tezacaftor, and ivacaftor in patients 6 to <12 years of age were within the range of exposure observed in patients 12 years of age and older (Studies 1 and 2).
[0029] The recommended dose of TRIKAFTA for patients 12 years of age and older and children 6 years of age and older is 2 tablets in the morning (each tablet contains 100 mg elexacaftor and 100 mg tezacaftor) if weighing 30 kg or more. The recommended dose of TRIKAFTA for patients 6 to 11 years of age weighing less than 30 kg is two tablets (each containing elexacaftor 50 mg / tezacaftor 25 mg / ivacaftor 37.5 mg) in the morning and one tablet (each containing ivacaftor 75 mg) in the evening, for a total of elexacaftor 200 mg / tezacaftor 100 mg / ivacaftor 300 mg per day. The FDA does not recommend the use of TRIKAFTA in patients with moderate hepatic impairment (Child-Pugh class B). However, if used, the TRIKAFTA dose should be reduced by alternating one and two tablets daily in the morning only.
[0030] TRIKAFTA is a co-packaged fixed-dose combination tablet of elexacaftor, tezacaftor, and ivacaftor with ivacaftor tablets. Both tablets are for oral administration. The elexacaftor, tezacaftor, and ivacaftor fixed-dose combination tablets are orange, capsule-shaped, film-coated tablets containing 100 mg elexacaftor, 50 mg tezacaftor, and 75 mg ivacaftor, or light orange, capsule-shaped, film-coated tablets containing 50 mg elexacaftor, 25 mg tezacaftor, and 37.5 mg ivacaftor. The following inactive ingredients are present: hypromellose, hypromellose acetate succinate, sodium lauryl sulfate, croscarmellose sodium, microcrystalline cellulose, and magnesium stearate. The tablet film coating contains hypromellose, hydroxypropyl cellulose, titanium dioxide, talc, iron oxide yellow, and iron oxide red. Ivacaftor tablets are available as light blue film-coated capsules containing 150 mg or 75 mg of ivacaftor and the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, hypromellose acetate succinate, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and sodium lauryl sulfate. The tablet film coating contains carnauba wax, FD&C Blue No. 2, PEG 3350, polyvinyl alcohol, talc, and titanium dioxide. The printing ink contains ammonium hydroxide, triferric oxide, propylene glycol, and shellac.
[0031] The safety profile of TRIKAFTA is based on data from 510 CF patients aged 12 years and older in two double-blind, controlled studies (Studies 1 and 2) with 24-week and 4-week treatment periods. Eligible patients were also eligible to participate in an open-label extension safety study (up to 96 weeks of TRIKAFTA). A total of 257 CF patients aged 12 years and older received at least one dose of TRIKAFTA in the two controlled studies. In Study 1, serious adverse reactions that occurred more frequently in patients treated with TRIKAFTA compared with placebo were rash (1% vs. <1%) and influenza (1% vs. 0%). The most common adverse drug reactions with TRIKAFTA (occurring in ≥ 5% of patients and ≥ 1% more frequently than placebo) were headache, upper respiratory tract infection, abdominal pain, diarrhea, rash, increased alanine aminotransferase, nasal congestion, increased blood creatine phosphokinase, increased aspartate aminotransferase, epistaxis, rhinitis, influenza, sinusitis, and increased blood bilirubin.
[0032] In Study 1, the incidence of adverse reactions of transaminase elevations (AST and / or ALT) was 11% in TRIKAFTA-treated patients and 4% in placebo-treated patients. The incidence of maximum total bilirubin elevations >2 × ULN was 4% in TRIKAFTA-treated patients and <1% in placebo-treated patients. Liver failure leading to transplantation while receiving TRIKAFTA has been reported in patients with cirrhosis and portal hypertension. The FDA recommends avoiding the use of TRIKAFTA in patients with pre-existing advanced liver disease unless the benefits are expected to outweigh the risks. If used in these patients, close monitoring is required after initiation of treatment. The FDA recommends that patients undergoing treatment with TRIKAFTA undergo a follow-up period of 1 year or more prior to initiation of TRIKAFTA. Liver function tests (ALT, AST, and bilirubin) are recommended for all patients every 3 months for the first year and annually thereafter. If liver function test values are significantly elevated, e.g., ALT or AST >5x upper limit of normal (ULN), or ALT or AST >3x ULN and bilirubin >2x ULN, treatment should be interrupted and laboratory values followed closely until the abnormalities resolve. After resolution, the FDA recommends considering the benefits and risks of resuming TRIKAFTA.
[0033] Non-congenital lens opacities / cataracts have been reported in pediatric patients treated with ivacaftor-containing regimens. The FDA recommends baseline and follow-up examinations for pediatric patients initiating TRIKAFTA treatment. Additional potential side effects of TRIKAFTA have been reported, including rash (Study 1, 10% with TRIKAFTA vs. 5% with placebo) and elevated blood pressure. The maximum increase from baseline in mean systolic and diastolic blood pressure was 3.5 mmHg and 1.9 mmHg, respectively, in TRIKAFTA-treated patients (baseline: systolic 113 mmHg, diastolic 69 mmHg) and 0.9 mmHg and 0.5 mmHg, respectively, in placebo-treated patients (baseline: systolic 114 mmHg, diastolic 70 mmHg).
[0034] ABBV-2222 (GLPG-2222, gallicaftor, 4-[(2R,4R)-4-({[1-(2,2-Difluoro-1,3-benzodioxol-5-yl)cyclopropyl]carbonyl}amino)-7-(difluoromethoxy)-3,4-dihydro-2H-chromen-2-yl]benzoic acid; CAS 1918143-53-9, e.g., WO2016 / 069757) is a Type I It is a CFTR corrector and is currently being tested in combination with the CFTR potentiator ABBV-3067 (see below) in an open-label Phase II trial (NCT03969888) in 78 CF patients aged 18 years or older who are homozygous for the F508del-CFTR mutation. The primary endpoint is absolute change from baseline in ppFEV1 at day 29, and secondary endpoints include absolute change from baseline in sweat chloride at day 29 and change in forced vital capacity (the total amount of air exhaled during forced expiratory volume test, pulmonary function tests). Several undisclosed dosing regimens of galicaftor and navocaftor are being tested. Additionally, gallicaftor was tested as part of a triple combination of CFTR modulators in an open-label Phase II study (NCT04853368), in which one cohort of patients with homozygous F508del-CFTR was treated with a fixed dose of gallicaftor and the potentiator, navocaftor, for 28 days, followed by 28 days of treatment with the triple combination of gallicaftor / navocaftor and the CFTR corrector, ABBV-119. ABBV-119 has a different mechanism of action than gallicaftor.An interim analysis after the dual treatment phase showed efficacy of the galicaftor / navocaftor dual combination on ppFEV1 ("favorable results"), but the addition of ABBV-119 did not provide any additional benefit, and the trial was discontinued (Abbvie's oral presentation at a press conference on April 29, 2022). Gallicaftor was previously tested as a single agent in a placebo-controlled Phase IIa study (NCT03119649). 59 CF patients aged 18 years or older who were homozygous for the F508del-CFTR mutation were treated for 4 weeks at doses of 50, 100, 200, and 400 mg once daily. The primary endpoint was the number of participants experiencing treatment-emergent adverse events by Day 43. Key secondary endpoints were change from baseline in ppFEV1 at Day 29, change from baseline in CFQ-R at Day 29, and change from baseline in sweat chloride concentration at Day 29. Gallicaftor was well tolerated and safe. No significant changes were observed in ppFEV1 and CFQ-R scores compared to placebo. The change in sweat chloride was significant in the 200 mg dose group (-15.8 mM vs. placebo). These data indicate that gallicaftor, as monotherapy, does not affect lung function in patients with homozygous F508del-CFTR CF at the doses tested. Gallicaftor demonstrated high efficacy (EC ) in electrophysiological recordings (transepithelial current clamp) in vitro in the presence of the potentiator GLPG1837 using differentiated human bronchial epithelial cells from homozygous F508del-CFTR donors. 50= 5 nM) (Wang, 2018). Additionally, galicaftor was tested in a fixed-dose combination with another potentiator, GLPG-2451, in a Phase 1b open-label study (NCT03540524). Ten CF patients homozygous for the F508del-CFTR mutation were treated with the galicaftor / GLPG-2451 combination for 2 weeks, followed by the addition of another CFTR modulator (GLPG-2737). An interim analysis at week 2 of treatment with gallicaftor and GLPG-2451 showed that the combination was well tolerated and safe during the 2-week treatment phase. Furthermore, key secondary endpoints improved versus baseline: ppFEV1 (+3%) and sweat chloride (-25mM) (Press Release Galapagos, October 24, 2018), demonstrating that galicaftor can partially correct F508del-CFTR function when used in combination with a potentiator.
[0035] PTI-801 (posenacaftor, CAS2095064-05-2; compound of Example 2 in WO2019 / 071078) can be classified as a type III CFTR corrector according to the examples in this application. PTI-801 was most recently tested in combination with a CFTR potentiator, PTI-808, and a CFTR amplifier, PTI-428, in a Phase 1 / 2 randomized, double-blind, placebo-controlled trial (NCT03500263). Thirty-one CF patients aged 18 years or older who carried at least one F508del-CFTR allele were randomized to receive the triple therapy combination or placebo. The triple combination was administered daily in fixed doses of PTI-428 (30 mg) plus low-dose PTI-801 (200 mg) and high-dose-tested PTI-808 (300 mg), or high-dose-tested PTI-801 (600 mg) and medium-dose PTI-808 (150 mg). Patients were first treated with PTI-808 or placebo for 7 days, followed by a 14-day triple combination treatment period, followed by a 7-day washout period during which no treatment was administered. Patients receiving combination therapy with high-dose PTI-801 experienced significant improvements in pulmonary function, with a 5% increase in mean absolute ppFEV1 at day 14 compared to pretreatment. These patients also experienced significant decreases in sweat chloride levels, with a 19 mM decrease at day 14 compared to pretreatment and a 24 mM decrease compared to placebo. Positive effects were also reported in patients who would not be enrolled in other CFTR modulator combination trials due to their propensity for rapid lung function decline: When treated with the combination regimen with 600 mg of PTI-801, these patients experienced a 6% improvement in ppFEV1 compared to baseline and an 8% improvement compared to placebo.
[0036] ABBV-3067 (navocaftor, GLPG-3067, (5-(3-Amino-5-((4-(trifluoromethoxy)phenyl)sulfonyl)pyridin-2-yl)-1,3,4-oxadiazol-2-yl)methanol), CAS 2159103-66-7, e.g., WO 2017 / 208115), as mentioned above, is a CFTR potentiator currently being analyzed in combination with gallicaftor in a Phase II trial (NCT03969888). Previously, a Phase I study was conducted in healthy volunteers, also in combination with gallicaftor, consisting of a single ascending dose part with single oral doses of navocaftor ranging from 15 to 1000 mg and a multiple ascending dose part with oral doses starting at 45 mg once daily for 14 days (NCT03128606). Navocaftor was generally well tolerated in healthy subjects at single doses up to 1000 mg and at doses up to 500 mg bid for 14 days. Navocaftor exposure was not significantly altered in the presence of gallicaftor, and gallicaftor exposure was similar in the presence of two different doses of navocaftor (Poster #36, North American Cystic Fibrosis Conference 2017, Indianapolis).
[0037] QBW-251 (Icenticaftor, 3-Amino-6-methoxy-N-[(2S)-3,3,3-trifluoro-2-hydroxy-2-methylpropyl]-5-(trifluoromethyl)pyridine-2-carboxamide, CAS 1334546-77-8, see e.g., WO 2011 / 113894), is a CFTR potentiator that was tested in a placebo-controlled Phase I / II study in a cohort of CF patients aged 18 years or older with a monoallelic CFTR class III / IV CFTR mutation, i.e., a mutation that places CFTR on the cell surface and can benefit from potentiation (NCT02190604). One of the primary endpoints was the change from baseline in the lung clearance index (LCI) after 14 days of treatment. The lung clearance index (LCI) is an index of ventilation inhomogeneity obtained from a multiple-breath washout test. 2.5 A mean change from baseline in LCI of more than 1 unit indicates improvement. Other efficacy endpoints were absolute change from baseline in ppFEV1 and change from baseline in sweat chloride concentration after 14 days of treatment. Patients treated with 450 mg isenticaftor (bid) had a mean change from baseline in LCI of more than 1 unit. 2.5The study demonstrated an improvement in CFTR target engagement and clinically meaningful improvements in lung function, including an improvement in FEV1 (-1.13 vs. placebo), a 6.5% increase vs. placebo, and a reduction in sweat chloride concentration (-8.4 mM vs. placebo). In the same study, and in contrast, treatment of a cohort of patients homozygous for the F508del-CFTR mutation with isenticaftor (450 mg bid) did not result in a reduction in sweat chloride or improvement in lung function, indicating the need for concomitant use with a CFTR corrector in this patient population (Kazani, 2021). In healthy volunteers, isenticaftor was well tolerated at all doses tested, up to 1000 mg bid at the SAD and 750 mg bid at the MAD. Icenticaftor 150 mg and 450 mg bid doses (across all patient subgroups) were well tolerated by CF patients with no unexpected events, deaths, or discontinuations (Kazani 2021).
[0038] Additionally, a placebo-controlled Phase II study (NCT02449018) evaluated isenticaftor in 92 patients aged 18-75 years with moderate to severe COPD and chronic bronchitis symptoms. Patients received 300 mg bid isenticaftor (N=64) or placebo (N=28) for 4 weeks in addition to their background COPD treatment. The primary endpoint was LCI after 4 weeks of treatment. 2.5 The primary secondary endpoint was the change from baseline in FEV1 after 4 weeks of treatment. The primary exploratory endpoints included the change from baseline in sweat chloride and plasma fibrinogen concentrations (markers of inflammation) after 4 weeks of treatment. Icenticaftor treatment significantly reduced LCI compared with placebo treatment. 2.5However, isenticaftor treatment improved FEV1 compared with placebo (+0.05-0.06 L, mean baseline 1.4-1.5 L), sweat chloride (-5.04 mM, mean baseline 23 mM), and plasma fibrinogen (-0.39 g / L, mean baseline 3.2 g / L), suggesting that isenticaftor treatment, compared with placebo, improved several areas of COPD lung disease. Improvements in bronchiectasis have been suggested (NCT02449018; Rowe, 2020). Currently, isenticaftor is undergoing a placebo-controlled Phase II clinical trial (NCT04396366) in subjects aged 18 years and older with bronchiectasis, at an oral dose of 300 mg bid and for a 12-week treatment period. An estimated 72 patients will be randomized 1:1 to drug or placebo treatment. The primary endpoint is the change from baseline in the bacterial load of potentially pathogenic microorganisms in sputum, measured as colony-forming units (CFU / mL), after 1 week of treatment. Key secondary endpoints measured after 12 weeks of treatment include change from baseline scores on the Quality of Life Questionnaire for Bronchiectasis, Respiratory Domain Only (QOL-B, a disease-specific questionnaire developed for non-cystic fibrosis bronchiectasis), change from baseline in fibrinogen plasma concentration, and rescue medication. These included change in (non-fatal) medication use (salbutamol / albuterol), change from baseline in FEV1, change from baseline in airway lumen measured by high-resolution computed tomography (HRCT), and change from baseline in global and regional airway air trapping severity measured by HRCT.

In Study 1 (NCT05033080), the new triple combination will be compared with TRIKAFTA in an estimated 400 CF patients aged 12 years or older who are heterozygous for the F508del-CFTR mutation and have a minimal function mutation on the other allele. After a 4-week TRIKAFTA run-in period, patients will be randomized 1:1 to either continuing TRIKAFTA or receiving a once-daily combination of banzacaftor, tezacaftor, and dutivacaftor (20 mg / 100 mg / 250 mg) for 48 weeks. The primary efficacy endpoint is improvement in lung function, as measured by the mean absolute change from baseline in ppFEV1, over 24 weeks of treatment.Key secondary endpoints, assessed at 24 weeks of treatment, include absolute change from baseline in sweat chloride, the proportion of participants with sweat chloride <60 mM and <30 mM (from baseline) by week 24. In Study 2 (NCT05076149), the new triple combination will be compared with TRIKAFTA in a blinded study in an estimated 550 CF patients aged 12 years or older who are homozygous for F508del-CFTR, heterozygous for F508del-CFTR and a gating or residual function CFTR mutation, or have at least one other TRIKAFTA-responsive CFTR mutation and no F508del-CFTR mutation. After a 4-week TRIKAFTA run-in period, patients will be randomized 1:1 to continue TRIKAFTA or receive a once-daily combination of banzacaftor, tezacaftor, and dutivacaftor (20 mg / 100 mg / 250 mg) for 48 weeks. The primary efficacy outcome was pulmonary function as measured by the mean absolute change from baseline in ppFEV1 through 24 weeks of treatment. Key secondary endpoints measured at 24 weeks of treatment were absolute change from baseline in sweat chloride, proportion of participants with sweat chloride <60 mM and <30 mM (from baseline) by week 24.
[0040] The efficacy and safety of the new triple combination, banzacaftor / tezacaftor / dutivacaftor, have previously been studied in a phase II trial in CF patients heterozygous for the F508del and minimal-function mutations in the CFTR gene (NCT03912233) or homozygous for the F508del-CFTR mutation. Heterozygous patients (N=58) received a triple combination of banzacaftor (5, 10, or 20 mg), tezacaftor 100 mg, and dutivacaftor 150 mg once daily for 4 weeks compared with placebo treatment, followed by an 18-day washout period from the triple combination to the tezacaftor / dutivacaftor dual combination. The primary efficacy outcome measure was improvement in lung function, as measured by the mean absolute change from baseline in ppFEV1, over 4 weeks of treatment. The ppFEV1 treatment differences between the new triple combination and placebo were +2.7% / +12.3% / +7.9% for the 5 mg / 10 mg / 20 mg banzacaftor groups. The key secondary endpoint, absolute change from baseline in sweat chloride over 4 weeks of treatment, was favorable for the new triple combination, with differences vs. placebo of -45.1 mM / -48.1 mM / -51.8 mM for the 5 mg / 10 mg / 20 mg banzacaftor groups. Homozygous patients (N=28) were randomized to either continue tezacaftor / ivacaftor (SYMKEVI) after a 4-week run-in period or receive the new triple combination of banzacaftor 20 mg / tezacaftor 100 mg / dutivacaftor 150 mg once daily for 4 weeks, followed by a 28-day washout period to the tezacaftor / ivacaftor dual combination. The primary efficacy outcome was improvement in pulmonary function as measured by the mean absolute change from baseline in ppFEV1 over 4 weeks of treatment. The ppFEV1 treatment difference between the new triple combination and the dual combination was +16.0%. The key secondary endpoint, absolute change from baseline in sweat chloride over 4 weeks of treatment, was favorable for the new triple combination, with a difference of + / -42.9 mM compared to the dual combination.The new triple combination was generally well tolerated (Vertex press release, July 28, 2021).
[0041] VX-561 (ivacaftor, N-[2-tert-butyl-4-[1,1,1,3,3,3-hexadeuterio-2-(trideuteriomethyl)propan-2-yl]-5-hydroxyphenyl]-4-oxo-1H-quinoline-3-carboxamide), CTP-656, CAS 1413431-07-8, e.g., WO2019 / 109021, WO2019 / 018395) is a deuterated form of ivacaftor for once-daily administration. This phase II study (NCT03911713) compared different doses of ivacaftor with the standard ivacaftor dose (150 mg bid = Kalydeco) in CF patients aged 18 years or older who harbored one of the following ivacaftor-responsive CFTR mutations in at least one allele: G551D, G178R, S549N, S549R, G551S, G1244E, S1251N, S1255P, or G1349D and were already taking ivacaftor. Patients (N=77) were randomized to either continue ivacaftor (150 mg bid) or receive 12 weeks of once-daily treatment with 25, 50, 150, or 250 mg of ivacaftor. The primary efficacy outcome was improvement in lung function, as measured by the mean absolute change from baseline in ppFEV1, over 12 weeks of treatment. The therapeutic difference in ppFEV1 of dutyvacaftor compared with ivacaftor was 150 mg / 250 mg once daily. The absolute change from baseline in sweat chloride over 12 weeks of treatment, a key secondary endpoint, was measured as +2.4 mM and -7.4 mM in the ivacaftor 150 mg / 250 mg once-daily groups compared with ivacaftor 150 mg bid. The mean c trough Plasma concentration (Mean c trough Plasma concentrations were 458 ng / mL and 1100 ng / mL for the 150 mg and 250 mg doses, compared with 952 ng / mL for the ivacaftor 150 mg bid dose.
[0042] CFTR correctors, including lumacaftor, tezacaftor, gallicaftor, Corr4a, elexacaftor, and vamocaftor, have been studied in vivo for their ability to restore folding of mutant CFTR (especially F508del-CFTR) and its trafficking to the cell surface. Trafficking to the cell surface can be analyzed by various assay techniques, including anti-CFTR immunoblotting (the CFTR "C band" represents transported mature CFTR), anti-CFTR cell surface ELISA, enzyme fragment complementation techniques, or CFTR-HRP fusion protein in recombinant cell lines expressing mutant CFTR proteins or primary cells from CF patients. Importantly, the combined use of collectors with different types of collector mechanisms showed additive effects on increasing cell surface expression of F508del-CFTR. This has been shown, for example, for elexacaftor + / - tezacaftor (type III corrector + / - type I corrector; Keating, 2018; Veit, 2020) or vamocaftor + / - tezacaftor (type III corrector + / - type I corrector; Davies, 2018) or type I + type II + type III corrector (Veit, 2018).
[0043] Mutant CFTR transported to the cell surface may still have impaired gating, and the addition of potentiators has been shown to significantly enhance the function of cell-surface F508del-CFTR. Various functional assays are available for analyzing CFTR function. For example, cellular expression of halide-sensitive yellow fluorescent protein can be used to measure iodide influx through functional CFTR (Galietta, 2001). Furthermore, Ussing chambers and electrophysiological measurements using recombinant epithelial cells or reconstituted bronchial epithelia from CF patients can be used to characterize the effects of CFTR modulators on CFTR function. For example, the addition of the potentiator ivacaftor to lumacaftor-corrected F508del-CFTR was shown to enhance CFTR function by nearly twofold in reconstituted bronchial epithelia from CF patients (van Goor, 2011), consistent with clinical trial data demonstrating improved FEV1 with ivacaftor addition in lumacaftor-treated patients (Boyle, 2014). Similarly, again using Ussing chamber data, we demonstrated the additivity of the type I corrector tezacaftor and the type III corrector elexacaftor in correcting F508del-CFTR function in reconstituted CF bronchial epithelium, and further demonstrated a two-fold enhancement of function with the addition of the potentiator ivacaftor. We also demonstrated an additive effect of the type III corrector elexacaftor on F508del-CFTR function compared with the combination of the type I corrector tezacaftor and the potentiator ivacaftor (Keating, 2018). This latter comparison is consistent with clinical trial data in patients homozygous for F508del-CFTR, in which the addition of elexacaftor to a baseline treatment of tezacaftor plus ivacaftor (SYMDEKO) resulted in a 10% increase in ppFEV1 (Keating, 2018). The FDA recognizes the predictive power of in vitro tests regarding clinical efficacy of CFTR modulators and has not recommended any drug for rare CFTR mutations based solely on in vitro evidence. CFTR modulators have been approved for this purpose (Ussing chamber assays in Fisher rat thyroid epithelial cells recombinantly expressing mutant CFTR; uspi SYMDEKO, uspi KALYDEKO, uspi TRIKAFTA).
[0044] Despite the availability of a variety of CFTR modulators with mechanisms complementary to many of the common mutations, patients have not fully restored CFTR function (as indicated by persistently elevated sweat chloride levels), nor has their lung function. These findings highlight the need for novel, additional CFTR corrector mechanisms with high efficacy that could be used alone or in addition to currently available or future background therapies (i.e., SYMDEKO or ORKAMBI or TRIKAFTA or [gallicaftor + navocaftor], and any additional background therapies) to enhance the efficacy of such CFTR modulator treatments.
[0045] CFTR correctors of novel mechanisms (i.e., not type I, not type II, not type III correctors) with potential in the prevention and treatment of CFTR-related diseases and disorders, in particular cystic fibrosis, in particular CFTR correctors such as compounds of formula (I) as defined below, including type I correctors (lumacaftor, tezacaftor, gallicaftor) and / or type II correctors (corrector 4a) and / or type III correctors (elexacaftor, vamo It has been found that when used in combination with CFTR correctors of other mechanisms, such as ivacaftor, navocaftor, isenticaftor, dutivacaftor, GLPG-1837, and GLPG-2451 (also known as CFTR potentiators), the compounds appear to have complementary, and even synergistic, effects in the treatment of CFTR-related diseases and disorders, particularly cystic fibrosis. Therefore, such combinations are considered particularly useful in the treatment of cystic fibrosis. The compounds of formula (I) can restore CFTR function in the absence and presence of potentiators, as measured by Ussing chamber assays in reconstituted tissue from CF patients with the F508del-CFTR mutation.
[0046] In addition, CFTR correctors, such as compounds of formula (I), particularly according to any one of embodiments 1) to 15), when used in combination with CFTR stabilizers, such as SION-638 or NBD1-A, are believed to have complementary and even synergistic effects in the treatment of CFTR-related diseases and disorders, particularly cystic fibrosis. Thus, such combinations are believed to be particularly useful in the treatment of cystic fibrosis. [Brief explanation of the drawings]

[0128] The compounds of formula (I) have at least three stereogenic or asymmetric centers that exist in either the (R)- or (S)-configuration, as defined in each embodiment defining such compounds of formula (I). In addition, compounds of formula (I) may have one or more additional stereogenic or asymmetric centers, such as one or more additional asymmetric carbon atoms. Thus, compounds of formula (I) may exist as a mixture of stereoisomers or, preferably, as pure stereoisomers. Mixtures of stereoisomers may be separated by methods known to those skilled in the art. When a given chemical name describes any stereogenic or asymmetric center as being in the (RS)-configuration, this means that such stereogenic or asymmetric center in such compounds may exist in the (R)-configuration, the (S)-configuration, or any mixture of epimers about such center.
[0129] Thus, for example, the compound (8R,11RS,14S,18S)-8-benzyl-14-isobutyl-N-(2-(3-methoxyisoxazol-5-yl)ethyl)-2,12,15-trimethyl-10,13,16,20-tetraoxo-11-(2,2,2-trifluoroethyl)-7,8,9,10,11,12,13,14,15,16,17,18,19,20-tetradecahydrooxazolo[4',5':5,6]benzo[1,2-p][1]oxa[4,7,10,14]tetraazacycloheptadecine-18-carboxamide is (8R,11R,14S,18S)-8-benzyl-14-isobutyl 1,2-Dimethyl-N-(2-(3-methoxyisoxazol-5-yl)ethyl)-2,12,15-trimethyl-10,13,16,20-tetraoxo-11-(2,2,2-trifluoroethyl)-7,8,9,10,11,12,13,14,15,16,17,18,19,20-tetradecahydrooxazolo[4',5':5,6]benzo[1,2-p][1]oxa[4,7,10,14]tetraazacycloheptadecine-18-carboxamide; compound, (8R,11S,14S,18S)-8-benzo and mixtures thereof. Similarly, in a chemical structure (as in Table S), a stereogenic or asymmetric center designated "abs" represents that center in the (R)- or (S)-configuration. A stereo or chiral center designated "&1" represents that stereo or chiral center in its respective (RS)-configuration, i.e., encompasses the respective (R)- or (S)-configuration or any mixture of epimers at such center.
[0130] When not used in reference to temperature, the term "about" placed before a numerical value "X" in this application denotes between 10% of XX and 10% of X+X, preferably between 5% of XX and 5% of X+X. In the specific case of temperatures, the term "about" placed before a temperature "Y" in this application denotes between temperatures Y-10°C and Y+10°C, preferably between Y-5°C and Y+5°C, in particular between Y-3°C and Y+3°C. Room temperature means a temperature of about 25°C. When the term n equivalents (n is a number) is used in this application, it is intended that within the scope of this application n means about n, preferably n means exactly n.
[0131] Whenever the words "between" or "to" are used to describe a numerical range, it is understood that the endpoints of the stated range are expressly included in that range. This means, for example, that when a temperature range is stated to be between 40°C and 80°C (or 40°C to 80°C), the endpoints 40°C and 80°C are included in the range; or, when a variable is defined as an integer between 1 and 4 (or 1 to 4), it means that the variable is the integer 1, 2, 3, or 4.
[0132] The term "essentially," in the context of the present invention, is understood to particularly mean that each amount / purity / time, etc., is at least 90 percent, particularly at least 95 percent, and especially at least 99 percent of the respective total. For example, when used in the term "essentially simultaneous exposure," in cases where chronic / steady-state exposure to pharmaceutically active ingredients is intended, it is understood to particularly mean that each exposure results in simultaneous exposure of pharmaceutically effective amounts of all combined active ingredients for at least 90 percent, particularly at least 95 percent, and especially at least 99 percent of the relevant time, i.e., relevant days.

[0146] Preparative HPLC for chiral separations In most cases, the desired diastereomer can be isolated or purified by standard preparative-scale HPLC according to standard methods well known to those skilled in the art. In some cases, the use of chiral chromatography columns is recommended to separate complex mixtures of diastereomers. Best results are obtained when using chiral stationary phase columns, such as Chiralpak IA, IB, or IC columns based on immobilized amylose or cellulose chiral phases, with an isocratic elution based on mixtures of MeCN with EtOH or MeOH in ratios varying from 9:1 to 1:9. To compensate for the presence of ionizable functional groups in the compounds to be purified, modifiers such as 0.1% diethylamine for basic derivatives or 0.1% formic acid for acidic derivatives can be added to the solvent mixture. In some cases, supercritical fluid chromatography was used using the same chiral stationary phase columns described above with an isocratic elution consisting of 50% to 90% supercritical carbon dioxide with EtOH, MeOH, or a 1:1 EtOH:MeCN mixture. Detection: UV / Vis.

[0272] Combination Effect Experiment: Restoration of F508del-CFTR Function in Recombinant U2OS Cell Line This assay uses U2OS cells (DiscoveRx, #93-0987C3) expressing the human F508del-CFTR chloride channel and a halide-sensitive mutant of yellow fluorescent protein (YFP Topaz F46L / H148Q / I152L; US2006 / 0257934A1), which reports the influx of exogenously added iodide (a surrogate ion) through functional surface CFTR, based on the property of YFP to bind iodide and quench its fluorescence.
[0273] Cells are seeded at 20,000 cells / well in 384-well 384w black clear-bottom plates in 40 μl / well of growth medium (McCoy's 5a (#36600-021, Gibco) + 10% FBS Gibco + penicillin / streptomycin) containing various CFTR collectors at the indicated concentrations. The final DMSO concentration in the assay is 0.1%. Cells are incubated with compounds for 24 h at 37°C, 5% CO2.

Remove the PBS+ completely and replenish the cells with 15 μL of PBS+. Then, add 5 μL of a 4x concentrated stock solution of potentiator or vehicle in dilution buffer (PBS+, 0.4 μM forskolin, 0.2% bovine serum albumin (fatty acid-free), pH 7.4) and incubate for 30 min in the dark. The final DMSO concentration in the assay is 0.5%. The plate was then transferred to a FLIPR Tetra (Fluorescence Imaging Plate Reader, Molecular Devices: excitation 470–495 nm; emission: 526–585 nm) and a baseline fluorescence reading of the YFP signal was taken for 6 seconds (10 x 0.6 s intervals). 25 µL of iodide buffer (137 mM NaI; 2.7 mM KCl; 1.5 mM KH2PO4; 8.1 mM Na2HPO4, 1 mM CaCl2; 0.5 mM MgCl2, pH 7.4) was then added and fluorescence readings continued for 70 seconds (50 x 0.6 s intervals; 20 x 2 s intervals) to assess YFP quenching due to CFTR-mediated iodide influx. For analysis, fluorescence traces were aligned and normalized to the last time point before iodide addition (normalized fluorescence = 1). Normalized fluorescence values obtained 14 seconds after iodide addition are used to assess the degree of YFP quenching and thus CFTR function.
