An Evaluation Of Single And Dual Long-Acting Bronchodilator Therapy As Effective Interventions In Maintenance Therapy-Naïve Patients With COPD.

Background: Ideally, treatment recommendations for maintenance therapy-naïve patients with COPD should be based on studies conducted specifically in this population. We have reviewed evidence from previous studies of pharmacological treatments in maintenance therapy-naïve patients with COPD and performed a new post-hoc analysis of dual bronchodilator treatment in this population, aiming to assess the effectiveness of these interventions.

Materials And Methods: A literature review identified clinical trials that included analyses of patients with COPD who were maintenance therapy-naïve with long-acting β-agonists (LABA) or long-acting muscarinic antagonists (LAMA).

AMPLIFY: a randomized, Phase III study evaluating the efficacy and safety of aclidinium/formoterol vs monocomponents and tiotropium in patients with moderate-to-very severe symptomatic COPD.

Background: AMPLIFY assessed the efficacy and safety of aclidinium bromide/formoterol fumarate (AB/FF) vs its monocomponents and tiotropium (TIO) in patients with moderate-to-very severe symptomatic COPD (NCT02796677).

Methods: In this 24-week, Phase III, double-dummy, active-controlled study, symptomatic patients (COPD Assessment Test score ≥10) were randomized to twice-daily AB/FF 400/12 µg, AB 400 µg, or FF 12 µg, or once-daily TIO 18 µg. Co-primary endpoints were change from baseline at week 24 in 1-hour morning post-dose FEV (AB/FF vs AB) and in pre-dose (trough) FEV (AB/FF vs FF).

Efficacy of aclidinium/formoterol 400/12 µg, analyzed by airflow obstruction severity, age, sex, and exacerbation history: pooled analysis of ACLIFORM and AUGMENT.

Background: Aclidinium/formoterol 400/12 µg is a twice-daily maintenance bronchodilator for COPD. This post hoc study evaluated aclidinium/formoterol vs aclidinium 400 µg, formoterol 12 µg, or placebo in patient subgroups.

Patients And Methods: Data were pooled from two 24-week Phase III clinical trials (ACLIFORM and AUGMENT).

ACTIVATE: the effect of aclidinium/formoterol on hyperinflation, exercise capacity, and physical activity in patients with COPD.

The Phase IV, 8-week, randomized, double-blind, placebo-controlled ACTIVATE study (NCT02424344) evaluated the effect of aclidinium/formoterol (AB/FF) 400/12 μg twice daily on lung hyperinflation, exercise capacity, and physical activity in patients with moderate-to-severe COPD. Patients received AB/FF (n=134) or placebo (n=133) (1:1) via the Genuair™/Pressair dry powder inhaler for 8 weeks. From Weeks 5 to 8, all patients participated in behavioral intervention (BI; daily messages providing step goals).

Physical activity patterns and clusters in 1001 patients with COPD.

We described physical activity measures and hourly patterns in patients with chronic obstructive pulmonary disease (COPD) after stratification for generic and COPD-specific characteristics and, based on multiple physical activity measures, we identified clusters of patients. In total, 1001 patients with COPD (65% men; age, 67 years; forced expiratory volume in the first second [FEV], 49% predicted) were studied cross-sectionally. Demographics, anthropometrics, lung function and clinical data were assessed.

Analysis of nocturnal actigraphic sleep measures in patients with COPD and their association with daytime physical activity.

Background: Sleep disturbances are common in patients with chronic obstructive pulmonary disease (COPD) with a considerable negative impact on their quality of life. However, factors associated with measures of sleep in daily life have not been investigated before nor has the association between sleep and the ability to engage in physical activity on a day-to-day basis been studied.

Aims: To provide insight into the relationship between actigraphic sleep measures and disease severity, exertional dyspnoea, gender and parts of the week; and to investigate the association between sleep measures and next day physical activity.

Effect of aclidinium bromide on cough and sputum symptoms in moderate-to-severe COPD in three phase III trials.

Background: Cough and sputum are troublesome symptoms in chronic obstructive pulmonary disease (COPD) and are associated with adverse outcomes. The efficacy of aclidinium bromide 400 µg twice daily in patients with stable COPD has been established in two phase III studies (ACCORD COPD I and ATTAIN) and a phase IIIb active-comparator study. This analysis evaluated cough-related symptoms across these studies.

Aclidinium improves exercise endurance, dyspnea, lung hyperinflation, and physical activity in patients with COPD: a randomized, placebo-controlled, crossover trial.

Background: This study evaluated the effects of aclidinium bromide, a long-acting muscarinic antagonist indicated for maintenance treatment of chronic obstructive pulmonary disease (COPD), on exercise endurance, dyspnea, lung hyperinflation, and physical activity.

Methods: In this randomized, double-blind, crossover study, patients with stable COPD and moderate-to-severe airflow limitation received aclidinium 400 μg twice daily or placebo via Genuair®/Pressair(®a) for 3 weeks (2-week washout between treatment periods). The primary endpoint was change from baseline to Week 3 in endurance time, measured by constant work rate cycle ergometry testing at 75% peak incremental work rate.

Aclidinium bromide improves exercise endurance and lung hyperinflation in patients with moderate to severe COPD.

Background: Static and dynamic lung hyperinflation are associated with exercise impairment and poor outcomes in COPD patients. Aclidinium bromide is a novel, long-acting inhaled muscarinic antagonist currently in development for COPD treatment.

Methods: Patients with moderate to severe COPD (N = 181) were randomized to once-daily aclidinium 200 μg or placebo for 6 weeks.
