NCT01621867

A Randomised, Double-blind, Placebo-controlled Phase 2B Clinical Trial of Repeated Application of Gene Therapy in Patients With Cystic Fibrosis

Study Summary

Cystic fibrosis is a genetic condition where epithelial cells, including from the respiratory tract, have an abnormal function of a surface protein, the cystic fibrosis transmembrane conductance regulator (CFTR) protein resulting from abnormal gene expression. The trial will assess the clinical efficacy, safety \& tolerability and gene expression following repeated nebulised doses of a gene product coding for a normal CFTR protein, with the primary outcome of the trial assessing lung function.
