Vertex's Cystic Fibrosis Drug Gets FDA Nod for Children

Read MoreHide Full Article

Vertex Pharmaceuticals Incorporated (VRTX - Free Report) announced FDA approval for its cystic fibrosis drug, Kalydeco (ivacaftor), for expanded use in children aged 12 months to two years.

The approval was based on data from an ongoing phase III study, ARRIVAL, evaluating 25 children who have one of 10 mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. A similar line-extension application is under review in the EU with a decision expected in the first half of next year. Meanwhile, Vertex is conducting a phase III study to get Kalydeco approved to treat infants under 12 months of age. Data from this phase III study is expected in the second half of 2018.

So far this year, Vertex’s shares have gained 15.5% against the industry’s decline of 5%.

Kalydeco is a key revenue driver for Vertex. The drug generated sales of $253 million in the quarter, rising 33.2% year over year due to increase in the number of eligible patient population.

Presently, Kalydeco is approved for the treatment of patients with CF, two years and older, who have one of 38 ivacaftor-responsive mutations in the CFTR gene. Supported by a consistent expansion in patient population, Kalydeco is now labelled to treat approximately 6,000 people with CF globally.

Vertex is looking to get Kalydeco approved in additional patient populations and is studying it in combination with other CF candidates.

A combination of Kalydeco and tezacaftor (VX-661) gained FDA approval in February and was launched as Vertex’s third CF medicine, Symdeko, for the treatment of patients with CF twelve years of age and older who are F508del homozygous or who have at least one mutation that is responsive to tezacaftor/ivacaftor. Approval in the EU for Symdeko is expected in the second half of 2018.  Symdeko is off to a strong start in the United States and is expected to be a significant contributor to sales in 2018.

Vertex is also evaluating two next-generation CFTR correctors (VX-659 and VX-445) in phase III studies as part of a triple combination with tezacaftor and ivacaftor. Vertex is evaluating both the combinations in two separate studies for F508del/Min and F508del homozygous patients. Enrolment in all these phase III studies is expected to be completed in second half of 2018 with a regulatory submission planned for mid-2019.
