Restore CFTR Function
Ivacaftor (Kalydeco®) is an oral medication that was the first drug available that targeted the underlying cause of CF – the defective CFTR protein. Ivacaftor helps facilitate the opening of the chloride channel on the cell surface to allow chloride and sodium (salt) to move in and out of the cell.
Ivacaftor is approved for children ages 1 and older who have at least one of 38 ivacaftor-responsive CFTR mutations. In clinical trials, people with CF who took the drug had improved lung function, reduced pulmonary exacerbations, increased weight and improved quality of life measures.
In December 2017, a phase 3 trial for children ages 1 to 2 showed that ivacaftor was generally well tolerated, and that there were no new safety concerns in this population. Two phase 3 studies of ivacaftor in infants ages 0 to 2 are ongoing.
This drug was developed by Vertex Pharmaceuticals, Inc. with significant scientific, clinical and financial support from the Cystic Fibrosis Foundation. The drug development was conducted within the Therapeutics Development Network.
