~ Positive Phase 1b Data Confirms Overdose Protection for Highest Dosage Form of PF614-MPAR ~
SAN DIEGO, CA / ACCESS Newswire / January 22, 2025 / 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 interim data from its second clinical trial to evaluate PF614-MPAR for overdose protection. Clinical study PF614-MPAR-102, 'A Single and Multiple Dose Study to Evaluate the Pharmacokinetics of Oxycodone and PF614 when PF614 Capsule is Co-Administered with Nafamostat as a Combination of Immediate Release Solution and Extended Release Capsule Formulations (PF614-MPAR) in Healthy Subjects,' was designed to evaluate the full dosage range of PF614-MPAR, study potential food effects, and to conduct a multiple ascending dose study with the final PF614-MPAR combination. In 2024, PF614-MPAR received Breakthrough Therapy designation from the U.S. Food and Drug Administration (FDA), and had its development bolstered by a $14 million multi-year award from the National Institute on Drug Abuse (NIDA) to continue studying the PF614-MPAR overdose protection observed in an initial clinical study, PF614-MPAR-101.
The PF614-MPAR-102 study showed that a 100 mg dosage form of PF614-MPAR provides overdose protection when a greater-than-prescribed dose is consumed at one time. Subjects were studied as their own control and received three doses of the overdose-protected PF614-MPAR versus PF614. The subjects receiving the MPAR product had a significantly lower (p=0.0019) total maximum blood concentration of oxycodone (Cmax) compared to PF614 alone, an indication of overdose protection. As designed, subjects who received a single 100 mg dose of PF614 or PF614 MPAR showed no difference in Cmax values (p=0.523). Additionally, safety data from the trial showed that there were no unexpected adverse events from either PF614 or PF614-MPAR. The trial will now continue to enroll the final cohorts of Part 1 of the study and then move to Part 2, which is designed to examine potential food effects. Part 3 will then evaluate repeat dosing of PF614 vs. PF614-MPAR over 4.5 days. The aggregation of interim data allows the Company to focus on perfecting a final drug product to move to commercialization.
Dr. Bill Schmidt, Chief Medical Officer of Ensysce, commented, "Clinical data from our initial study demonstrated the unique overdose protection built into PF614-MPAR, which led to the FDA's Breakthrough Therapy designation, a first for an opioid drug product. This second study builds on the initial data and further demonstrates that MPAR is a vital tool to limit unwanted overdoses from prescription medications. Our goal of bringing PF614-MPAR and a new generation of safer analgesics to the market to alleviate suffering from severe pain is being realized."
Dr. Lynn Kirkpatrick, CEO of Ensysce, added, "We are delighted with the positive early interim data which confirms that MPAR provides overdose protection in the planned dosage range for our PF614-MPAR drug product. We will continue to quickly execute the final stages of this study using the Translational Pharmaceutics® platform of Quotient Sciences in advance of our work with our new commercial manufacturing partner to prepare this very unique product for the market. We look forward to completing this highly important three-part trial and generating additional evidence to conduct productive discussions with the FDA on the path to registration for the first overdose-protected opioid."
