Tezacaftor + ivacaftor (Symdeko®)
Restore CFTR Protein
Tezacaftor + ivacaftor (Symdeko®) is a combination therapy combining tezacaftor, a compound designed to move the defective CFTR protein to the proper place in the airway cell surface, with ivacaftor, which 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.
Tezacaftor/ivacaftor (Symdeko®) is approved for individuals 12 years and older with two copies of the most common cystic fibrosis mutation, F508del, as well as for individuals who have a single copy of one of 153 specified mutations -- regardless of their other mutation.

This program is sponsored by Vertex Pharmaceuticals Inc. and partially funded by the Cystic Fibrosis Foundation. The program is being conducted within the Therapeutics Development Network.
