Effect of Aclidinium Bromide on Major Cardiovascular Events and Exacerbations in High-Risk Patients With Chronic Obstructive Pulmonary Disease: The ASCENT-COPD Randomized Clinical Trial.

ABSTRACT: Importance:There is concern that long-acting muscarinic antagonists increase cardiovascular morbidity or mortality in patients with chronic obstructive pulmonary disease (COPD). Objective:To determine the cardiovascular safety (noninferiority) and efficacy (superiority) of aclidinium bromide, 400 ?g twice daily, in patients with COPD and cardiovascular disease or risk factors. Design, Setting, and Participants:Multicenter, randomized, placebo-controlled, double-blind, parallel-design study conducted at 522 sites in North America. A total of 3630 patients with moderate to very severe COPD and either a history of cardiovascular disease or at least 2 atherothrombotic risk factors were randomized; follow-up occurred for up to 3 years until at least 122 major adverse cardiovascular events (MACE) occurred. The first patient was enrolled on October 16, 2013 and the last on August 22, 2016. The final patient completed follow-up on September 21, 2017. Interventions:Patients were randomized to receive aclidinium (n = 1812) or placebo (n = 1818) by dry-powder inhaler, twice daily for up to 3 years. Main Outcomes and Measures:The primary safety end point was time to first MACE over up to 3 years (hazard ratio [HR] 1-sided 97.5% CI noninferiority margin?=?1.8). The primary efficacy end point was the annual COPD exacerbation rate during the first year of treatment. Secondary outcomes included an expanded MACE definition (time to first MACE or serious cardiovascular event of interest) and annual rate of exacerbations requiring hospitalization. Results:Among 3589 patients analyzed (mean age, 67.2 years; 58.7% male), 2537 (70.7%) completed the study. Of these, 69 (3.9%) aclidinium and 76 (4.2%) placebo patients had a MACE (HR, 0.89; 1-sided 97.5% CI, 0-1.23); the expanded MACE definition included 168 (9.4%) aclidinium vs 160 (8.9%) placebo patients with events (HR, 1.03; 1-sided 97.5% CI, 0-1.28). Annual moderate to severe exacerbation rates (aclidinium, 0.44; placebo, 0.57; rate ratio, 0.78; 2-sided 95% CI, 0.68-0.89; P?

Project description:IntroductionLong-acting muscarinic antagonists (LAMAs), long-acting β2-agonists (LABAs), inhaled corticosteroids (ICS), and their combinations, are recommended for the treatment of chronic obstructive pulmonary disease (COPD). This study aimed to determine whether the safety and efficacy of aclidinium bromide differs by baseline maintenance LABA and ICS therapies.MethodsASCENT-COPD was a phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study of patients with moderate-to-very severe COPD and increased cardiovascular risk. Patients were randomized 1:1 to receive aclidinium 400 μg or placebo twice daily, via a multidose dry-powder inhaler for up to 3 years. Outcomes included time to first major adverse cardiovascular events (MACE), all-cause mortality, change from baseline in trough forced expiratory volume in 1 s (FEV1), and COPD assessment test (CAT) total score over 3 years, and annual moderate-to-severe COPD exacerbation rate in patients receiving aclidinium or placebo with maintenance LABA monotherapy, ICS monotherapy, LABA + ICS (fixed/free), or no maintenance therapy (neither LABA nor ICS) at baseline.ResultsA total of 3589 patients were included (LABA, n = 227; ICS, n = 290; LABA + ICS, n = 2058; no maintenance, n = 1130). Aclidinium did not increase the risk of MACE or all-cause mortality versus placebo, regardless of baseline maintenance treatment. Reductions in moderate-to-severe exacerbation rates were observed with aclidinium versus placebo in all subgroups [LABA 43% (P = 0.046); ICS 25% (P = 0.202); LABA + ICS 22% (P = 0.003); no maintenance 18% (P = 0.130)]. Aclidinium improved morning trough FEV1 irrespective of baseline therapy and CAT total scores, except for LABA and ICS subgroups, versus placebo at several time points.ConclusionIn patients with moderate-to-severe COPD and CV risk factors, the addition of aclidinium to maintenance therapy with LABA or LABA + ICS provided further benefit.Trial registrationClinicalTrials.gov identifier NCT01966107.

Project description:PurposeChronic obstructive pulmonary disease (COPD) exacerbations are associated with increased risk of major adverse cardiovascular events (MACE) and mortality. Here, we investigate whether the safety and efficacy of aclidinium bromide differ due to exacerbation history in patients with COPD and increased cardiovascular risk.Patients and methodsASCENT-COPD was a Phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study of patients with moderate-to-very severe COPD and increased cardiovascular risk. Patients were randomized 1:1 to receive aclidinium or placebo twice daily for up to 3 years. Outcomes included time to first MACE and all-cause mortality over 3 years, exacerbation rate during the first year on-treatment, and change in baseline pre-dose forced expiratory volume in 1 second (FEV1) over 3 years. This pre-specified subgroup analysis compared outcomes in patients receiving aclidinium vs placebo. The comparison of patients with vs without an exacerbation history was added following a protocol amendment to increase enrollment in the primary study.ResultsOf 3589 patients, 2156 (60.1%) had ≥1 moderate or severe exacerbations in the prior year, compared with 1433 (39.9%) without prior exacerbations. Although patients with an exacerbation history had numerically higher rates of MACE and mortality regardless of treatment, aclidinium did not increase risk of MACE (≥1: hazard ratio [HR] 0.79, 95% confidence interval [CI]: 0.54-1.16; none: HR 1.27, 95% CI: 0.65-2.47; interaction P=0.233) or all-cause mortality (≥1: HR 1.08, 95% CI: 0.81-1.43; none: HR 0.66, 95% CI: 0.36-1.22; interaction P=0.154), regardless of exacerbation history. Aclidinium reduced the exacerbation rate vs placebo irrespective of exacerbation history (≥1: rate ratio [RR] 0.80, 95% CI: 0.68-0.94; none: RR 0.69, 95% CI: 0.54-0.89; interaction P=0.340) and improved FEV1 (interaction P=0.633).ConclusionIn patients with moderate-to-very severe COPD and increased cardiovascular risk, aclidinium did not increase risk of MACE or mortality and reduced exacerbation rate vs placebo, regardless of exacerbation history.Clinical trial registrationClinicalTrials.gov Identifier: NCT01966107.

Project description:BackgroundA growing body of evidence suggests a role for oral bacteria in lung infections. This systematic review aimed to analyse the association between poor periodontal status and the frequency of chronic obstructive pulmonary disease (COPD) exacerbations.MethodsPubMed, Embase, Web of Science, CINAHL and Medline were searched for studies published until May 2020, with no language restriction. Studies reporting periodontal condition, or periodontal treatment outcomes, with data on the frequency of exacerbations of COPD, were identified. The primary outcome was the frequency of exacerbations and secondary outcomes included quality of life (QoL) and hospitalisation. Quality and risk of bias assessment were carried out using the Newcastle Ottawa Scale for observational studies, Robins-1 tool for non-randomised intervention studies and Cochrane risk of bias assessment (RoB-2) tool for randomised clinical trials. Studies were assessed for eligibility and quality by two assessors independently.ResultsSearches identified 532 records and 8 met the inclusion criteria. Included studies were three clinical trials, one prospective cohort study, one case-control, and three cross-sectional studies. A narrative synthesis was performed. The data from intervention studies showed reduction in the frequency of exacerbations following periodontal treatment. Data from observational studies suggest association of worse plaque scores and fewer teeth with exacerbation, but not pocket depth or clinical attachment loss. Better periodontal health was also associated with reduced frequency of COPD exacerbations, hospitalisations and improved quality of life in COPD patients. Due to the high heterogeneity no meta-analysis was performed. The quality of some of the included studies was low and there was evidence of a high risk of bias.ConclusionThe data supports possible association between poor periodontal health, the frequency of exacerbations, hospitalisation and quality of life in COPD patients. The evidence is of moderate to low certainty and is limited by high risk of bias suggesting the need for well-designed and adequately powered randomised controlled trials, to inform future research and clinical practice.

Project description:Patients with chronic obstructive pulmonary disease (COPD) have elevated cardiovascular risk, and myocardial injury is common during severe exacerbations. Little is known about the prevalence, magnitude, and underlying mechanisms of cardiovascular risk in community-treated exacerbations.To investigate how COPD exacerbations and exacerbation frequency impact cardiovascular risk and myocardial injury, and whether this is related to airway infection and inflammation.We prospectively measured arterial stiffness (aortic pulse wave velocity [aPWV]) and cardiac biomarkers in 98 patients with stable COPD. Fifty-five patients had paired stable and exacerbation assessments, repeated at Days 3, 7, 14, and 35 during recovery. Airway infection was identified using polymerase chain reaction.COPD exacerbation frequency was related to stable-state arterial stiffness (rho = 0.209; P = 0.040). Frequent exacerbators had greater aPWV than infrequent exacerbators (mean ± SD aPWV, 11.4 ± 2.1 vs. 10.3 ± 2.0 ms(-1); P = 0.025). Arterial stiffness rose by an average of 1.2 ms(-1) (11.1%) from stable state to exacerbation (n = 55) and fell slowly during recovery. In those with airway infection at exacerbation (n = 24) this rise was greater (1.4 ± 1.6 vs. 0.7 ± 1.3 ms(-1); P = 0.048); prolonged; and related to sputum IL-6 (rho = 0.753; P < 0.001). Increases in cardiac biomarkers at exacerbation were higher in those with ischemic heart disease (n = 12) than those without (n = 43) (mean ± SD increase in troponin T, 0.011 ± 0.009 vs. 0.003 ± 0.006 ?g/L, P = 0.003; N-terminal pro-brain natriuretic peptide, 38.1 ± 37.7 vs. 5.9 ± 12.3 pg/ml, P < 0.001).Frequent COPD exacerbators have greater arterial stiffness than infrequent exacerbators. Arterial stiffness rises acutely during COPD exacerbations, particularly with airway infection. Increases in arterial stiffness are related to inflammation, and are slow to recover. Myocardial injury is common and clinically significant during COPD exacerbations, particularly in those with underlying ischemic heart disease.
