Vertex Plans Mid-year Cystic Fibrosis NDA

Share

Vertex Pharmaceuticals plans to file an NDA by mid-year and use a priority review voucher for its cystic fibrosis (CF) combination drug, once-daily vanzacaftor/tezacaftor/deutivacaftor (vanza triple). The decision to submit the NDA comes as the company is reporting Phase 3 data that show the treatment met all primary and key secondary endpoints in two randomized controlled trials in people with CF ages 12 years and older.

“We are very pleased with today’s results, which demonstrate the vanza triple is non-inferior to [Vertex’s] Trikafta in improving lung function and superior to Trikafta in lowering levels of sweat chloride in people living with CF, setting a new standard for the level of CFTR protein function achievable, and raising the very high bar set by Trikafta,” the company says.

Vertex notes that vanza triple was well tolerated in all three studies, and safety was similar between the vanza triple and Trikafta treatment groups in the SKYLINE 102 and SKYLINE 103 studies. “The safety of the vanza triple in children 6 to 11 years old was similar to the safety in people 12 years of age and older,” it says.
