A Study to Evaluate Safety and Efficacy of BOTOX in Adults With Moderate COPD

This is a prospective, double-blind, randomized, placebo-controlled, investigator-initiated clinical trial to assess the safety, tolerability, and efficacy using an approved drug, BOTOX, in moderate COPD participants. Forty participants with moderate COPD, defined as mMRC Dyspnea Scale scores of grades 2 or 3 and CAT scores of 12 to 20, will be included. If eligibility criteria are met, subjects will be randomized to either the treatment arm (BOTOX) or placebo, treated on day one and observed for 90 days for safety and efficacy.
