FDA approves Symdeko to treat cystic fibrosis F508del mutation,- Vertex.

Vertex Pharmaceuticals Incorporated announced that the FDA approved Symdeko (tezacaftor/ivacaftor and ivacaftor) for treating the underlying cause of cystic fibrosis (CF) in people ages 12 and older who have two copies of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or who have at least one mutation that is responsive to tezacaftor/ivacaftor.

Symdeko is Vertex�s third medicine approved to treat the underlying cause of CF. Vertex is ready to launch Symdeko and will begin shipping it to pharmacies in the United States this week.

In November 2017, the New England Journal of Medicine published the results of two Phase III studies of Symdeko. These studies, named EVOLVE and EXPAND, enrolled approximately 750 people with CF ages 12 and older with two copies of the F508del mutation or with one F508del mutation and one mutation that results in residual CFTR function. Across both studies, patients treated with Symdeko experienced statistically significant and clinically meaningful improvements in lung function and other measures of disease, with a favorable safety profile. The most common adverse events, regardless of treatment group, included infective pulmonary exacerbation and cough. The first data from the ongoing EXTEND rollover study, also presented in November, show that the lung function improvements and the safety and tolerability profiles seen in EVOLVE and EXPAND were sustained for up to 48 total weeks of Symdeko treatment.
