The Topic Trial - Study to Determine the Safety and Efficacy of Ivacaftor

Completed · Phase 2 · Has a placebo group

Conditions studied: Chronic Obstructive Pulmonary Disease, Chronic Bronchitis

In brief

The study is a Phase 2 Study to establish the safety and efficacy of a drug called Ivacaftor (VX-770) in patients with chronic obstructive pulmonary disease (COPD), chronic bronchitis, and acquired CFTR dysfunction as detected by sweat chloride analysis. The design is a pilot, randomized (3:1, active:placebo), double-blind, placebo-controlled study. Approximately 40 subjects with COPD will be randomized.
