Improvements in Lung Function with Nebulized Revefenacin in the Treatment of Patients with Moderate to Very Severe COPD: Results from Two Replicate Phase III Clinical Trials.

ABSTRACT:

Background

Revefenacin, a novel, lung-selective, long-acting muscarinic antagonist, has been developed for nebulized therapy for chronic obstructive pulmonary disease (COPD). We present the results of replicate Phase III efficacy and safety studies of revefenacin in patients with moderate to very severe COPD.

Methods

In 2 double-blind, parallel-group studies, (Study 0126 and Study 0127), patients ? 40 years old were randomized to revefenacin 88 ?g, revefenacin 175 ?g or placebo administered once daily by standard jet nebulizer for 12 weeks. The primary endpoint was 24-hour trough forced expiratory volume in 1 second (FEV₁) on day 85. Secondary efficacy endpoints included overall treatment effect (OTE) on trough FEV₁ and peak FEV₁ (0-2 hours after first dose). Safety assessments included treatment-emergent adverse events.

Results

At day 85, revefenacin 88 µg and 175 µg improved trough FEV₁ versus placebo in Study 0126 (by 79 mL [p=0.0003] and 146 mL [p<0.0001]) and Study 0127 (by 160 mL and 147 mL; both p<0.0001). Compared with placebo, pooled data of revefenacin 88 µg and 175 µg increased OTE trough FEV₁ by 115 mL and 142 mL (both p<0.001) and increased peak FEV₁ by 127 mL and 129 mL (both p<0.0001). Revefenacin 175 µg demonstrated greater improvements in FEV₁ in concomitant long-acting beta2-agonist patients and in more severe patients than revefenacin 88 µg. Adverse events were minor.

Conclusion

Revefenacin, administered once daily for 12 weeks to patients with moderate to very severe COPD, demonstrated clinically significant improvements in trough FEV₁ and OTE FEV₁. Revefenacin was generally well tolerated with no major safety concerns.

Project description:BACKGROUND:Revefenacin is a long-acting muscarinic antagonist that was recently approved for the nebulized treatment of chronic obstructive pulmonary disease (COPD). Although shorter duration studies have documented the efficacy of revefenacin in COPD, longer-term efficacy has not been described. In a recent 52-week safety trial, revefenacin was well tolerated and had a favorable benefit-risk profile. Here we report exploratory efficacy and health outcomes in patients receiving revefenacin 175 μg or 88 μg daily during the 52-week trial. METHODS:In this randomized, parallel-group, 52-week trial (NCT02518139), 1055 participants with moderate to very severe COPD received revefenacin 175 μg or 88 μg in a double-blind manner, or open-label active control tiotropium. RESULTS:Over the 52-week treatment period, both doses of revefenacin, as well as tiotropium, elicited significant (all p < 0.0003) improvements from baseline in trough forced expiratory volume in 1 s (FEV1). The trough FEV1 profile (least squares mean change from baseline) for revefenacin 175 μg ranged from 52.3-124.3 mL and the trough FEV1 profile for tiotropium ranged from 79.7-112.8 mL. In subgroup comparisons, the effect of revefenacin on trough FEV1 was comparable in patients taking concomitant long-acting β-agonists, with or without inhaled corticosteroids, with patients who were not taking these medications. There were statistically significant (p < 0.05) improvements in all measured health status outcomes (evaluated using St. George's Respiratory Questionnaire, COPD Assessment Test, Clinical COPD Questionnaire and Baseline and Transition Dyspnea Index) from 3 months onward, in all treatment arms. CONCLUSIONS:Significant sustained improvements from baseline in trough FEV1 and respiratory health outcomes were demonstrated for 175-μg revefenacin over 52 weeks, further supporting its use as a once-daily bronchodilator for the nebulized treatment of patients with COPD. TRIAL REGISTRATION:NCT02518139 ; Registered 5 August 2015.

Project description:Bronchodilation with muscarinic antagonists, β2-agonists, and inhaled corticosteroids remains the foundation of pharmaceutical treatment for patients with stable COPD. These drugs are delivered from a variety of devices, including dry powder inhalers, pressurized metered-dose inhalers, soft-mist inhalers, or nebulizers. Nebulized delivery is often preferable in patients who are elderly, are cognitively impaired, are unable to generate sufficient inspiratory force to use their inhaler, have difficulty coordinating hand-breath activity, are too dyspneic to hold their breath for a sufficient time, and/or may be acutely ill. Revefenacin, a once-daily long-acting muscarinic antagonist for nebulization recently approved by the US FDA for the treatment of patients with COPD, was discovered and developed using "duration and lung selectivity-by-design." This strategy selected a molecule with a high lung-selective index to maximize bronchodilation and limit systemic anti-muscarinic side effects. In early-phase clinical studies, revefenacin for nebulization led to a rapid onset of bronchodilation that was sustained for 24 hrs in patients with moderate to severe COPD. Revefenacin also demonstrated minimal systemic exposure and good tolerability in these studies. Statistically and clinically significant improvements in lung function (ie, peak and/or trough FEV1) relative to placebo were observed with revefenacin in Phase III clinical trials of up to 3 months in patients with moderate to very severe COPD. Revefenacin was well tolerated in Phase III clinical trials with a low incidence of systemic antimuscarinic adverse events, which is consistent with its lung-selective design. There was no evidence of an increased risk of major cardiovascular events. Patient-reported outcome data from clinical trials indicated statistically significant improvements in several disease-specific measures. Revefenacin 175 μg for nebulization provides an effective once-daily treatment option for patients with moderate to very severe COPD who require or prefer nebulized therapy.

Project description:BackgroundRevefenacin, a once-daily, long-acting muscarinic antagonist delivered via standard jet nebulizer, increased trough forced expiratory volume in 1 s (FEV1) in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) in prior phase 3 trials. We evaluated the efficacy of revefenacin in patients with markers of more severe COPD.MethodsA post hoc subgroup analysis of two replicate, randomized, phase 3 trials was conducted over 12 weeks. Endpoints included least squares change from baseline in trough FEV1, St. George's Respiratory Questionnaire (SGRQ) responders, and transition dyspnea index (TDI) responders at Day 85. This analysis included patient subgroups at high risk for COPD exacerbations and compared patients who received revefenacin 175 μg and placebo: severe and very severe airflow limitation (percent predicted FEV1 30%-< 50% and < 30%), 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) D, reversibility (≥ 12% and ≥ 200 mL increase in FEV1) to short-acting bronchodilators, concurrent use of long-acting β agonists and/or inhaled corticosteroids, older age (> 65 and > 75 years), and comorbidity risk factors.ResultsRevefenacin demonstrated significant improvements in FEV1 versus placebo at Day 85 among the intention-to-treat (ITT) population and all subgroups. Additionally, there was a greater number of SGRQ and TDI responders in the ITT population and the majority of subgroups analyzed among patients who received revefenacin versus placebo. For the SGRQ responders, the odds of response (odds ratio > 2.0) were significantly greater in the revefenacin arm versus the placebo arm among the severe airflow obstruction, very severe airflow obstruction and 2011 GOLD D subgroups. For the TDI responders, the odds of response (odds ratio > 2.0) were significantly greater among the severe airflow obstruction subgroup and patients aged > 75 years.ConclusionsRevefenacin showed significantly greater improvements in FEV1 versus placebo in the ITT population and all subgroups. Furthermore, there were a greater number of SGRQ and TDI responders in the ITT population, and in the majority of patient subgroups among patients who received revefenacin versus placebo. Based on the data presented, revefenacin could be a therapeutic option among patients with markers of more severe COPD.Trial registrationClinical trials registered with www.clinicaltrials.gov (Studies 0126 [NCT02459080; prospectively registered 22 May 2015] and 0127 [NCT02512510; prospectively registered 28 July 2015]).

Project description:RationaleThe purpose of this study was to investigate the clinical efficacy and safety of a fixed-dose combination of mometasone furoate/formoterol fumarate (MF/F) administered via a metered-dose inhaler in subjects with moderate-to-very severe chronic obstructive pulmonary disease (COPD).MethodsThis multicenter, double-blind, placebo-controlled trial had a 26-week treatment period and a 26-week safety extension. Subjects (n = 1196), at least 40 years old, were current or ex-smokers randomized to twice-daily inhaled MF/F 400/10 μg, MF/F 200/10 μg, MF 400 μg, F 10 μg, or placebo. The trial's co-primary endpoints were mean changes from baseline, as area under the curve (AUC), in forced expiratory volume (FEV(1)) over 0-12 hours (AUC(0-12 h) FEV(1)) with MF/F versus MF, and in morning (AM) pre-dose (trough) FEV(1) with MF/F versus F after 13 weeks of treatment. Key secondary endpoints were the effects of MF/F on respiratory health status using the Saint George's Respiratory Questionnaire (SGRQ), symptom-free nights, partly stable COPD at 26 weeks, and time to first COPD exacerbation.ResultsThe largest improvements in AUC(0-12 h) FEV(1) were observed with MF/F 400/10 μg and MF/F 200/10 μg. Serial spirometry results demonstrated that bronchodilator effects with MF/F occurred rapidly (within 5 minutes), persisted for 12 hours after dosing, and were sustained over the 26-week treatment period. Similar findings were observed for AM pre-dose FEV(1), for which effects were further investigated, excluding subjects whose AM FEV(1) data were incorrectly collected after 2 days from the last dose of study treatment. Improvements in SGRQ scores surpassed the minimum clinically important difference of more than four units with both MF/F treatments. At 26 weeks, no notable between-treatment differences in the occurrence and nature of adverse events (AEs) were reported. No unexpected AEs were observed. Overall, 90 subjects reported AEs considered to be treatment-related, the most common of which were lenticular opacities, dysphonia, and oral candidiasis.DiscussionIn conclusion, MF/F treatments improved lung function and respiratory health status, reduced exacerbations, and were well tolerated in subjects with moderate-to-very severe COPD.
