Intervention Details:
    Drug: VX-770
    150 mg tablet, oral use, twice daily every 12 hours (q12h)
Detailed Description:

VX-770, a compound being developed by Vertex Pharmaceuticals Incorporated (Vertex) for the treatment of CF, is an orally bioavailable small molecule that targets the underlying defect in CF, the dysfunctional CFTR protein. In Phase 3 studies of VX-770 in patients with CF and a G551D CFTR mutation, improvements in CFTR function (measured by reduction in sweat chloride concentration) and improvements in lung function were observed.

Patients who are interested in the VX-770 Expanded Access should contact their CF physician about participation.

Physicians interested in participating as a site should contact 800-745-4484.
