ClinicalTrials.gov ID: NCT07418736
What this study is testing
What is CM326 dose 1?
CM326 dose 1 is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for chronic obstructive pulmonary disease.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- 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.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
