Long-acting antimuscarinic therapy in patients with chronic obstructive pulmonary disease receiving beta-blockers.

ABSTRACT:

Background

Beta-blocker therapies for cardiovascular comorbidities are often withheld in patients with chronic obstructive pulmonary disease (COPD) due to potential adverse effects on airway obstruction. We carried out a post hoc analysis to determine the efficacy and safety of aclidinium in patients with moderate-to-very severe COPD and increased cardiovascular risk receiving beta-blockers at baseline versus non-users.

Methods

ASCENT-COPD was a Phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study. Patients were randomized 1:1 to aclidinium or placebo twice-daily for up to 3 years. Outcomes included risk of (time to first) major adverse cardiovascular events (MACE), all-cause mortality, and lung function over 3 years, and exacerbations over 1 year.

Results

Of 3589 patients, 1269 (35.4%) used beta-blockers and 2320 (64.6%) were non-users at baseline. Aclidinium did not statistically increase the risk of MACE (beta-blocker user: hazard ratio 1.01 [95% CI 0.62-1.64]; non-user: 0.80 [0.51-1.24]; interaction P = 0.48) or all-cause mortality (beta-blocker user: 1.13 [0.78-1.64]; non-user: 0.89 [0.62-1.26]; interaction P = 0.35), in patients using beta-blockers. Aclidinium reduced annualized rate of moderate-to-severe COPD exacerbation (beta-blocker user: rate ratio 0.75 [95% CI 0.60-0.94, P = 0.013]; non-user: 0.79 [0.67-0.93, P = 0.005]), delayed time to first exacerbation, and improved lung function versus placebo. There was greater trough FEV₁ benefit in beta-blocker users versus non-users (least squares mean difference at 52 weeks: 111 mL [95% CI 74 mL-147 mL] versus 69 mL [42 mL-97 mL]; interaction P = 0.041).

Conclusions

This post hoc analysis supports long-acting anti-muscarinic use with concomitant beta-blockers in patients with moderate-to-very severe COPD and cardiovascular comorbidity.

Project description:PurposeIn the absence of head-to-head clinical trials comparing the once-daily, long-acting beta2-agonists olodaterol and indacaterol for the treatment of chronic obstructive pulmonary disease (COPD), an indirect treatment comparison by systematic review and synthesis of the available clinical evidence was conducted.MethodsA systematic literature review of randomized, controlled clinical trials in patients with COPD was performed to evaluate the efficacy and safety of olodaterol and indacaterol. Network meta-analysis and adjusted indirect comparison methods were employed to evaluate treatment efficacy, using outcomes based on trough forced expiratory volume in 1 second (FEV1), Transition Dyspnea Index, St George's Respiratory Questionnaire total score and response, rescue medication use, and proportion of patients with exacerbations.ResultsEighteen trials were identified for meta-analysis (eight, olodaterol; ten, indacaterol). Olodaterol trials included patients of all severities, whilst indacaterol trials excluded patients with very severe COPD. Concomitant maintenance bronchodilator use was allowed in most olodaterol trials, but not in indacaterol trials. When similarly designed trials/data were analyzed for change from baseline in trough FEV1 (liters), the following mean differences (95% confidence interval) were observed: trials excluding concomitant bronchodilator: indacaterol 75 mcg versus olodaterol 5 mcg, -0.005 (-0.077 to 0.067), and indacaterol 150 mcg versus olodaterol 5 mcg, 0.020 (-0.036 to 0.077); trials with concomitant tiotropium: indacaterol 150 mcg versus olodaterol 5 mcg, 0.000 (-0.043 to 0.042). In sensitivity analyses of the full network, results for change from baseline in trough FEV1 favored indacaterol, but this dataset suffered from trial design heterogeneity. For the other endpoints investigated, no statistically significant differences were found when analyzed in the full network.ConclusionWhen compared under similar trial conditions, olodaterol and indacaterol have similar efficacy in patients with COPD. This research highlights the importance of considering the concomitant COPD medication when evaluating treatment effects in COPD.
