简要总结
This study is a multi-center, randomized, double-blind, placebo-controlled Phase II clinical study to evaluate the efficacy, safety, PK characteristics, PD effects and immunogenicity of CM326 in subjects with moderate to Severe Chronic Obstructive Pulmonary Disease.
The study consists of a screening period of up to 4 weeks, a randomized treatment period of 24 to 52 weeks, and a 12-week safety follow-up period.
