- In head-to-head clinical trials, ALYFTREK was non-inferior on ppFEV1 and superior in reducing sweat chloride compared to TRIKAFTA - - Approximately 3,800 people in Canada are now eligible for ALYFTREK, with up to 60 people potentially eligible for a medicine that treats the underlying cause of their disease for the first time - TORONTO, July 22, 2025 /CNW/ - Vertex Pharmaceuticals today announced that Health Canada has granted Marketing Authorization for PrALYFTREKTM (vanzacaftor/tezacaftor/deutivacaftor), a new triple combination therapy for patients living with cystic fibrosis (CF) ages 6 years and older who have at least one F508del mutation or another responsive mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. ALYFTREK brings a potentially transformative therapy to up to 60 people living with CF in Canada who were not previously eligible for a CFTR modulator. As the first once-daily CFTR modulator, ALYFTREK may also provide a new treatment option and flexibility for approximately 3,800 people given the need to take CFTR modulators with fat-containing food. "ALYFTREK represents the next generation of CFTR modulator treatment and is a testament to our long-standing goal to address the underlying cause of cystic fibrosis, treat more people living with CF, and bring more people to normal levels of CFTR function," said Michael Siauw, General Manager at Vertex Pharmaceuticals (Canada) Incorporated. "With once-daily dosing, eligibility in 113 additional mutations, and the potential to lower sweat chloride levels even further, ALYFTREK brings us one step closer to achieving this goal." This approval is based on a comprehensive Phase 3 pivotal program, including more than 1,000 patients across more than 20 countries and more than 200 sites. The Phase 3 studies in people with CF ages 12 years and older met their primary endpoint (non-inferiority on absolute change from baseline in ppFEV1 compared to TRIKAFTA) and all key secondary endpoints (including absolute change from baseline in sweat chloride [SwCl] compared to TRIKAFTA). In the Phase 3 study of children with CF ages 6-11 years, ALYFTREK demonstrated safety, the primary endpoint. Secondary endpoints, such as absolute change from baseline in ppFEV1 and absolute change from baseline in SwCl, demonstrate the benefit of ALYFTREK in this age group. ALYFTREK was generally well tolerated across all studies. "For Canadian patients and families, the approval of ALYFTREK represents significant progress towards improved care," said Dr. Bradley Quon, Medical and Research Director of the Adult Cystic Fibrosis Program at St. Paul's Hospital, and Associate Professor of Medicine in the Faculty of Medicine at the University of British Columbia. "Lower levels of sweat chloride combined with the convenience of a once-a-day treatment provides a new option that has the potential to both improve CFTR function and reduce treatment burden." ALYFTREK is currently approved in the U.S., UK and European Union and is under regulatory review in Switzerland, Australia and New Zealand. About Cystic Fibrosis Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 109,000 people, including 94,000 people in North America, Europe and Australia. CF is a progressive, multi-organ disease that affects the lungs, liver, pancreas, GI tract, sinuses, sweat glands and reproductive tract. CF is caused by a defective and/or missing CFTR protein resulting from certain mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF, and these mutations can be identified by a genetic test. While there are many different types of CFTR mutations that can cause the disease, the vast majority of people with CF have at least one F508del mutation. CFTR mutations lead to CF by causing CFTR protein to be defective or by leading to a shortage or absence of CFTR protein at the cell surface. The defective function and/or absence of CFTR protein results in poor flow of salt and water into and out of the cells in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus, chronic lung infections and progressive lung damage that eventually leads to death for many patients. The median age of death is in the 30s, but with treatment, projected survival is improving. Today Vertex CF medicines are treating over 75,000 people with CF in more than 60 countries on six continents. This represents 2/3 of the diagnosed people with CF eligible for CFTR modulator therapy. Sweat chloride, which measures CFTR function, is used to diagnose CF. The diagnostic threshold for CF is SwCl ≥60 mmol/L, while levels between 30-59 indicate CF is possible and more testing may be needed to make the diagnosis of CF. A SwCl level of <30 mmol/L is seen in people who carry one copy of a CFTR gene mutation but do not have any manifestation of disease (carriers). At a population level, higher levels of SwCl are associated with more severe disease. Restoring CFTR function leads to lower levels of SwCl. Restoring SwCl levels below 30 mmol/L has long been the ultimate treatment goal for Vertex, as levels below 30 mmol/L are considered normal and are typical of CF carriers who do not have disease. About ALYFTREKTM (vanzacaftor/tezacaftor/deutivacaftor) In people with CF, mutations in the CFTR gene lead to decreased quantity and/or function of the CFTR protein channel at the cell surface. Vanzacaftor and tezacaftor are designed to increase the amount of CFTR protein at the cell surface by facilitating the processing and trafficking of the CFTR protein. Deutivacaftor is a potentiator designed to increase the channel open probability of the CFTR protein delivered to the cell surface to improve the flow of salt and water across the cell membrane. ALYFTREK is approved in the U.S., UK, and Canada for the treatment of cystic fibrosis (CF) in patients aged 6 years and older who have at least one F508del mutation or another responsive mutation in the CFTR gene. ALYFTREK is approved in the European Union for the treatment of CF in patients ages 6 years and older who have at least one non-class I mutation in the CFTR gene. Boxed Warning Elevated transaminases have been observed in some patients treated with ALYFTREK. Cases of liver failure leading to transplantation and death have been reported in patients with and without a history of liver disease taking a fixed dose combination drug containing elexacaftor, tezacaftor, and ivacaftor, which contains one same (tezacaftor) and one similar (ivacaftor) active ingredient as ALYFTREK. Liver injury has primarily been reported within the first 6 months following initiation of elexacaftor/tezacaftor/ivacaftor. See full ALYFTREK Product Monograph for further details.
