Full title

Observational Study of Outcomes in Cystic Fibrosis Patients with Selected Gating Mutations on a CFTR Allele (The VOCAL Study)

The study is being done to learn more about the effectiveness of Kalydeco in CF patients with the following specific gene mutaions: G178R, S549N, S549R, G551S, G1244E, S1251N, S1255P or G1349D. The study also looks to explore the effect of Kalydeco on your quality of life. This is an observational study. This means that your cystic fibrosis treatment and medical care will not change because you are participating in this study and the sponsor will not pay for Kalydeco. Your doctor will continue to make all decisions regarding your proper treatment and care. No part of this study is experimental.
