FDA OK’s Expanded Use for Vertex’s Symdeko

Share

FDA has expanded the indication of Vertex Pharmaceuticals’ Symdeko (tezacaftor/ivacaftor) tablets for treating pediatric patients aged six years and older with cystic fibrosis who have certain genetic mutations. Last year, Symdeko was approved to treat patients ages 12 and older who had the same specific genetic mutations.

 

Cystic fibrosis is caused by a defective protein that results from mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, an agency release says. There are about 2,000 known mutations of the CFTR gene, and Symdeko is used to treat patients who have two copies of the most common type of mutation – F508del mutation – or who have at least one of the mutations in the CFTR gene that is responsive to the active ingredients in Symdeko based on in vitro data or clinical evidence. “Patients with cystic fibrosis and their caregivers should speak with a health care professional and have tests performed to understand which gene mutations patients have and whether Symdeko is likely to work for them,” FDA says.
