Vertex's Kalydeco Gets EU Approval To Treat CF In Infants

 | Dec 11, 2019 02:42AM ET

Vertex Pharmaceuticals Inc. (NASDAQ:VRTX) announced that the European Commission has granted marketing authorization to its cystic fibrosis (CF) drug Kalydeco (ivacaftor) for expanded use in infants aged from six to less than 12 months with at least one of specified nine mutations in the CFTR gene.

Following this nod, CF patients as young as six months in Europe can now have access to Kalydeco to treat the underlying cause of CF.

Kalydeco was approved by the FDA to address the same patient population in April 2019.

The approval was based on data from an ongoing open-label phase III study, ARRIVAL, which evaluated children aged less than 24 months with a CFTR gating mutation.

The safety profile of the study was similar to the observations in earlier phase III studies of older children and adult CF patients, which demonstrated improvements in sweat chloride, indicating a secondary endpoint.

Notably, in Europe, Kalydeco was until now approved to treat CF in children aged 12 months and older with at least one of specified nine mutations in the CFTR gene. The drug is also approved for CF patients aged 18 years and above with R117H mutation in the CFTR gene.

Shares of Vertex have surged 32.9% so far this year compared with the industry’s increase of 6.1%.
