Revefenacin, a once-daily, lung-selective, long-acting muscarinic antagonist for nebulized therapy: Safety and tolerability results of a 52-week phase 3 trial in moderate to very severe chronic obstructive pulmonary disease

BackgroundPrior replicate 12-week phase 3 trials demonstrated that once-daily doses of revefenacin inhalation solution at 88 μg and 175 μg produced significant bronchodilation over 24 h post dose in patients with moderate to very severe chronic obstructive pulmonary disease (COPD). The objective was to characterize the safety profile of revefenacin 88 μg and 175 μg over 52 weeks of treatment.MethodsIn this randomized, parallel-group, 52-week...
