Abstract
BACKGROUND: Bronchodilators are central to the symptomatic management of patients with COPD.Previous data have shown that inhaled indacaterol improved numerous clinical outcomes over placebo. METHODS: This systematic review explored the efficacy and safety of indacaterol in comparison with tiotropium or bid long-acting β 2 -agonists (TD-LABAs) for treatment of moderate to severe COPD. Randomized controlled trials were identified after a search of different databases of published and unpublished trials. RESULTS: Five trials (5,920 participants) were included. Compared with tiotropium, indacaterol showed statistically and clinically significant reductions in the use of rescue medication and dyspnea(43% greater likelihood of achieving a minimal clinically important difference [MCID] in the transitional dyspnea index [TDI]; number needed to treat for benefit [NNTB] 5 10). Additionally,the MCID in health status was more likely to be achieved with indacaterol than with tiotropium (OR = 1.43; 95% CI, 1.22–1.68; P = .00001; [NNTB ]= 10). Trough FEV 1 was significantly higher at the end of treatment with indacaterol than with TD-LABAs (80 mL, P = .00001). Similarly, indacaterol signifi cantly improved dyspnea (61% greater likelihood of achieving an MCID in TDI, P = .008) and health status (21% greater likelihood of achieving an MCID in St. George’s Respiratory Questionnaire, P 5 .04) than TD-LABA. Indacaterol showed similar levels of safety and tolerability to both comparators. CONCLUSIONS: Available evidence suggests that indacaterol may prove useful as an alternative to tiotropium or TD-LABA due to its effects on health status, dyspnea, and pulmonary function.
