A Study of CM512 in Subjects With Moderate-to-Severe Chronic Obstructive Pulmonary Disease

This is a Phase II, multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of CM512 in adults with moderate-to-severe chronic obstructive pulmonary disease (COPD) receiving triple or double inhaled maintenance therapy, and having had 1 or more documented COPD exacerbations in the 12 months prior to Visit 1. Subjects will receive CM512, or placebo, administered via subcutaneous injection at the study site, over a 52 week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.
