SAN ANTONIO — Once-daily revefenacin does not prolong QT interval and offers an acceptable 1-year cardiovascular safety profile for treatment of chronic obstructive pulmonary disease (COPD), according to a study presented at the CHEST Annual Meeting, held October 6-10, 2018, in San Antonio, Texas.

Because cardiovascular disease is common in people with COPD, researchers analyzed cardiovascular safety data from 3 randomized trials of revefenacin as well as data from a thorough QT study in healthy individuals.

Healthy individuals received once-daily therapeutic (175 μg) and supratherapeutic (700 μg) revefenacin doses in a phase 1, placebo-controlled study (n=48). The researchers assessed the association between daily revefenacin treatment at 88 μg and 175 μg with cardiovascular safety in patients with moderate to very severe COPD in 2 phase 3 trials of 12 weeks’ duration (n=619 and n=611). An active-controlled phase 3 safety trial of 52 weeks’ duration was also included in the analysis (n=699). Prespecified major cardiovascular adverse events (MACE) were evaluated in all patients with COPD receiving treatment.

There was no clinically meaningful effect of single-dose revefenacin on cardiac repolarization in healthy individuals. Additionally, in the 52-week trial, the investigators observed no changes in 12-lead electrocardiographic recordings associated with daily doses of revefenacin 88 μg and 175 μg in patients with COPD. Additionally, the incidences of prolonged cardiac repolarization in the 52-week trial were similar between the revefenacin 175 μg (7.7%) and tiotropium (7.3%) groups.

Treatment with revefenacin 175 μg and 700 μg in single doses did not result in any cardiovascular-related treatment-emergent adverse events in healthy individuals. Following adjudication by a clinical end point committee, the researchers identified 4 MACE in the 12-week study, with 2, 1, and 1 MACE in the 88-μg revefenacin, 175-μg revefenacin, and placebo groups, respectively. In addition, a total of 26 MACE were recorded in the 52-week trial, all of which were reported in the treatment groups. Of these, only 1 (atrial fibrillation) was thought to be related to revefenacin.
