Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD)
Conditions
Brief summary
This is a multicenter, randomized, double-blind, placebo-controlled phase II clinical study to evaluate the efficacy and safety of RC1416 injection in patients with moderate to severe chronic obstructive pulmonary disease (COPD).
Detailed description
Each participant will receive the study treatment once every two weeks for a total treatment duration of 52 weeks. The study aims to evaluate the annualized rate of moderate or severe COPD exacerbations (AECOPD) and the change in FEV1 from baseline over the 52-week treatment period. The changes in FeNO, total IgE, eosinophil count, and TARC levels from baseline will be evaluated.
Interventions
There are two doses in this part. Each subjects will receive the drug by subcutaneous injection.
Each subjects will receive the placebo by subcutaneous injection.
