This 2 arm study will investigate the efficacy, safety and tolerability of RAR Gamma versus placebo in ex-smokers with moderate or severe emphysema treated with optimal COPD therapy. Following optimization of COPD therapy (up to 6 weeks) patients will be randomized to receive either RAR Gamma (5mg) or placebo once daily using a 2:1 ratio (active:placebo), in addition to their standard therapy. Following the double-blind treatment period, patients will enter a 4-week follow-up period. The anticipated time on study period is 1-2 years, and the target sample size is 100-500 individuals.
A Double-blind, Placebo-controlled Efficacy (as Assessed by Post-bronchodilator FEV1) and Safety Study of RAR Gamma in Subjects With Smoking-related, Moderate to Severe COPD With Emphysema Receiving Concurrent Optimised COPD Drug Therapy.
