NCT05292950

Brief Summary

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of ARO-MUC5AC in normal healthy volunteers (NHVs), patients with moderate-to-severe asthma and patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). In part 1 NHVs will receive a single dose of ARO-MUC5AC or placebo. In part 2 of the study, NHVs, adult patients with asthma, and adult patients with COPD will receive 3 doses of ARO-MUC5AC or placebo.
