How KALYDECO® Works
KALYDECO affects gating of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. KALYDECO is used in patients age 2 years and older who have at least one mutation in their CF gene that is responsive to KALYDECO.
In patients with a mutation in their CF gene that is responsive to KALYDECO, KALYDECO works to help the "gates" stay open longer, allowing more chloride ions to move into and out of the cells. The movement of chloride ions may help keep a balance of salt and water in the lungs. KALYDECO does not increase the number of CFTR proteins at the cell surface.
What is known about how KALYDECO works was learned from studies conducted in a lab. Keep in mind that results from laboratory studies do not always match how these medicines work in a person. If you have any questions about your treatment, please speak with your healthcare provider.
