Abstract

BackgroundReplicate, 12-week, phase 3 trials (0126 and 0127) of once-daily nebulized revefenacin 175 μg vs placebo demonstrated significant bronchodilation and improvements in health status in patients with moderate to very severe chronic obstructive pulmonary disease (COPD). This post hoc analysis evaluated improvement in patient-reported outcomes (PROs), including the St. George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), and Clinical COPD Questionnaire (CCQ) in both women and men. MethodsParticipants were pooled from the two 12-week studies (411 [51%] women and 401 [49%] men). Changes in PROs were assessed overall and separately in men and women. ResultsRevefenacin improved SGRQ and CAT total scores from baseline in both studies; improvement in CCQ total score reached significance only in 0126. In pooled data, a greater proportion of patients achieved clinically meaningful response in SGRQ score (≥4-unit decrease from baseline) with revefenacin vs placebo (odds ratio, 1.5; 95% confidence interval, 1.1–2.1; P = 0.012). Clinically meaningful responses were also seen in CAT (≥2-unit decrease from baseline) and CCQ (≥0.4-unit decrease from baseline) scores with revefenacin vs placebo. When stratified by sex, improvements from baseline in SGRQ, CAT, and CCQ scores following revefenacin vs placebo reached statistical significance only in women. ConclusionsMaintenance treatment with revefenacin improved health status in patients with moderate to very severe COPD; however, the effect was more pronounced for women than men.
