• Phase 3 Study to Assess PF614 Efficacy in Treating Post-Surgical Pain

SAN DIEGO, CA / ACCESSWIRE / September 19, 2024 / Ensysce Biosciences, Inc. (NASDAQ:ENSC) ("Ensysce" or the "Company"), a clinical-stage pharmaceutical company developing innovative solutions for severe pain relief while reducing the potential for opioid abuse and overdose, today announced it has submitted to the FDA its PF614-301 protocol of the study, "A Multicenter, Randomized, Double-Blind, Placebo-and Active-Controlled Study to Evaluate the Efficacy and Safety of PF614 for the Treatment of Moderate to Severe Pain after Abdominoplasty". Included in the Phase 3 study is the Company's statistical analysis plan for review and input by the FDA.

The study, once finalized with the FDA, will be conducted through four to six clinical sites in the United States, and is designed to assess the analgesic efficacy of PF614 compared to placebo in subjects with moderate-to-severe pain following abdominoplasty. Additionally, Ensysce will evaluate PF614 versus an active comparator, the use of rescue medication and the safety and tolerability of PF614.

Dr. Bill Schmidt, Chief Medical Officer of Ensysce, commented, "The review of this study protocol represents another key milestone that brings us one step closer to executing the last clinical phase of evaluation for PF614. We anticipate the results of this Phase 3 trial will continue to prove the positive qualities of PF614 over existing oxycodone products. We remain dedicated to bringing PF614, a ‘next-generation opioid', to market."

Dr. Lynn Kirkpatrick, CEO of Ensysce, offered, "We believe that the features of PF614 will be a game changer for the treatment of short-term severe pain. The fact that PF614 delivers the pain-relieving qualities of OxyContin but lasts twice as long, should alleviate the common problem of recurring breakthrough pain between dosing. In parallel with its reduced abuse potential, PF614 is anticipated to offer this market a superior pain product. We look forward to conducting this trial and expect results in late 2025."
