Trevena, Inc. announced that it has completed enrollment of its Phase 3 APOLLO-1 and APOLLO-2 pivotal efficacy studies of oliceridine (TRV130) in moderate-to-severe acute pain following bunionectomy and abdominoplasty. The APOLLO studies were designed based on the Phase 2 clinical trials of oliceridine that were successful in showing potential differentiation of oliceridine from morphine. The company expects top-line results to include measures of efficacy, safety, and tolerability of oliceridine. Both APOLLO trials are Phase 3, multicenter, randomized, double-blind, placebo-and active-controlled studies of oliceridine for the treatment of moderate to severe acute pain. The APOLLO-1 study is evaluating pain for 48 hours following bunionectomy, and the APOLLO-2 study is evaluating pain for 24 hours following abdominoplasty. In each trial, patients were randomized to receive placebo, morphine, or one of three regimens of oliceridine by patient-controlled analgesia (PCA) device for the management of their post-operative pain. Each study enrolled approximately 375 patients, allocated equally across study arms. The primary objective in each study is to evaluate the analgesic efficacy of oliceridine compared to placebo. Secondary endpoints include comparisons of efficacy, safety, and tolerability of oliceridine to morphine. Oliceridine, Trevena’s lead product candidate, is a next generation IV analgesic in Phase 3 development for the management of moderate-to-severe acute pain and has been granted Breakthrough therapy designation by the FDA. Oliceridine was specifically designed to improve conventional opioid pharmacology to deliver the pain-reducing potential of an opioid but with fewer associated adverse effects. In a Phase 2b clinical trial, oliceridine provided rapid and powerful analgesic efficacy while demonstrating a wider therapeutic window compared to morphine, suggesting it may be highly effective and well-tolerated for patients in need of strong analgesia. Oliceridine is an investigational product and has not been approved by the FDA or any other regulatory agency.
