Clinical Trial Summary

RV1729 is a new medicine being developed for possible treatment of asthma and smoking related lung disease (also known as chronic obstructive pulmonary disease - COPD).

The main purpose of this study is to investigate the safety, tolerability and pharmacokinetics of single and repeat doses of RV1729.
