NCT04026711

Brief Summary

A 14-week, randomized, placebo-controlled, double-masked clinical trial in 40 obese patients with poorly controlled asthma. The intervention is Mitoquinol (MitoQ) versus placebo. The primary aim of this pilot study is to determine if MitoQ improves airway reactivity in obese patients with asthma.
