Vertex Receives CHMP Positive Opinion for KAFTRIO

If approved, more than 1,500 children would be eligible for a medicine that can treat the underlying cause of their disease for the first time.

Vertex Pharmaceuticals Incorporated today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for the label extension of KAFTRIO (ivacaftor/tezacaftor/elexacaftor) in a combination regimen with ivacaftor, for the treatment of cystic fibrosis (CF) in patients ages 6 through 11 years old who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

“Today marks an important milestone for the treatment of children with CF in Europe. If approved, KAFTRIO (ivacaftor/tezacaftor/elexacaftor) in a combination regimen with ivacaftor will offer physicians a new treatment option for these young patients to help combat this life-shortening condition as early as possible,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex.

“The clinical data for ivacaftor/tezacaftor/elexacaftor plus ivacaftor in people with CF ages 6 through 11 with eligible CF genotypes demonstrated improvements in lung function, sweat chloride and respiratory symptoms and a safety and tolerability profile consistent with that observed in patients ages 12 years and older,” said Professor Marcus A. Mall, M.D., Head of the Department of Pediatric Respiratory Medicine, Immunology and Critical Care Medicine at Charité University Medical Center Berlin. “This medicine has already made a big impact on the lives of eligible people ages 12 years and above in Europe. The CF community is now looking forward to it being available for younger patients too, to enable treatment as early as possible in life.”

About Cystic Fibrosis
Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 83,000 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 early 30s.

About KAFTRIO (ivacaftor/tezacaftor/elexacaftor) in A Combination Regimen With 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. KAFTRIO® (ivacaftor/tezacaftor/elexacaftor) in combination with 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 by binding to different sites on the CFTR protein. 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 ivacaftor, tezacaftor and elexacaftor help hydrate and clear mucus from the airways.

KAFTRIO (ivacaftor/tezacaftor/elexacaftor) in combination with ivacaftor is approved in the European Union for the treatment of cystic fibrosis (CF) in patients ages 12 years and older who have at least one copy of the F508del mutation in the CFTR gene.
