Health Canada Grants Marketing Authorization for TRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for People With Cystic Fibrosis Aged 2 Years and Older With Certain Rare Mutations

-Approximately 200 people with certain rare CF mutations are now eligible for TRIKAFTA®-

TORONTO, July 15, 2024 /CNW/ - Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that Health Canada has granted Marketing Authorization for the expanded use of PrTRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for the treatment of cystic fibrosis (CF) in patients aged 2 years and older who have a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is responsive based on clinical and/or in vitro data. TRIKAFTA® was previously approved by Health Canada for use in people with CF aged 2 years and older with at least one F508del mutation and is now approved for 152 additional mutations.

“This expanded approval of TRIKAFTA for patients with a responsive mutation underscores the commitment of our scientists to the development of medicines for all people living with CF,” said Michael Siauw, General Manager at Vertex Pharmaceuticals (Canada) Incorporated. “We remain dedicated to the CF community and are excited for the hope this approval brings to newly eligible CF patients and families across the country.”

“The approval of TRIKAFTA for certain non-F508del mutations is a transformative moment for CF management in Canada,” said Elizabeth Tullis, M.D., Director of the Toronto Adult CF Clinic at St. Michael’s Hospital, Unity Health Toronto and Professor of Medicine, University of Toronto. “Many patients not previously eligible for CFTR modulators may now be able to benefit from a treatment that targets the underlying cause of their disease for the first time.”

The label update is based on data from multiple sources, including a 24-week randomized placebo-controlled double-blind study in patients aged 6 years and older who had at least one qualifying non-F508del mutation to evaluate the safety and efficacy of TRIKAFTA®. The study met its primary endpoint, TRIKAFTA® was generally well tolerated, and safety data were similar to those observed in previous studies. Additionally, published clinical data and robust in vitro data supported the expanded indication.

The full list of indicated mutations for TRIKAFTA can be found in the Health Canada-approved Product Monograph.

About Cystic Fibrosis

Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 92,000 people globally. 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 the 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 65,000 people with CF across 60 countries on six continents. This represents 2/3 of the diagnosed people with CF eligible for CFTR modulator therapy.

About PrTRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor)

In people with certain types of mutations in the CFTR gene, the CFTR protein is not processed or folded normally within the cell, and this can prevent the CFTR protein from reaching the cell surface and functioning properly. TRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is an oral medicine designed to increase the quantity and function of the CFTR protein at the cell surface. Elexacaftor and tezacaftor work together to increase the amount of mature protein at the cell surface. Ivacaftor, which is known as a CFTR potentiator, is designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane. The combined actions of elexacaftor, tezacaftor and ivacaftor help hydrate and clear mucus from the airways. 

TRIKAFTA® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is a prescription medicine used for the treatment of cystic fibrosis (CF) in patients aged 2 years and older who have at least one copy of the F508del mutation, or another mutation responsive to TRIKAFTA®, in the CFTR gene. Patients should talk to their doctor to learn if they have an indicated CF gene mutation. It is not known if TRIKAFTA® is safe and effective in children under 2 years of age.
