Ensysce Biosciences Announces Completion of Clinical Portion of Human Abuse Potential Trial PF614-103
Completion of Clinical Portion Represents Critical Milestone Towards Commercialization
Nasal Opioid Abuse Being Explored for PF614
Data From Trial Expected in September 2022
SAN DIEGO, CA / ACCESSWIRE / August 23, 2022 / Ensysce Biosciences, Inc. ("Ensysce" or the "Company") (NASDAQ:ENSC)(OTC PINK:ENSCW), a clinical-stage biotech company applying transformative chemistry to improve prescription drug safety to reduce abuse and overdose, today announced that it has successfully completed the clinical portion of study PF614-103, ‘A Randomized, Double-blind, Placebo- and Active-Controlled Crossover Study to Evaluate the Intranasal Abuse Potential of PF614 Compared with Immediate-Release Oxycodone and Placebo in Non-Dependent Recreational Opioid Users' being conducted by Dr. Glen Apseloff, from Ohio Clinical Trials, Inc.
This trial is designed to test and confirm that manipulating and snorting PF614 will not result in subjects "liking" the product. Human Abuse Potential (HAP) studies are critical for gaining Abuse Deterrent labeling as outlined by the FDA. The global opioid epidemic is primarily driven by individuals abusing opioids through manipulation of current marketed products by crushing, snorting and through IV injections. Due to the unique mechanism of action of PF614, the FDA has not required Ensysce to perform an IV HAP study. Thus, the nasal HAP study is one of two important HAP studies in the clinical development of PF614. The second is an oral HAP study for which we look forward to providing an update shortly.
Dr. Lynn Kirkpatrick, CEO of Ensysce, commented, "Release of the active ingredient in PF614 requires exposure to trypsin, which is only found in the small intestine and not in the nasal mucosa, so we believe inhalation of PF614 will not result in oxycodone release. Similarly, trypsin is not found in the blood stream, and therefore, PF614 will not convert to the active drug if injected or absorbed into the circulation as shown in our PF614-MPAR-101 study. We are looking forward to reporting the final data from this 103 trial and expect to do so by the end of next month."
Dr. Nily Osman, Chief Medical Officer of Ensysce, stated, "We believe that this nasal HAP study will provide critical data to differentiate PF614 from other oxycodone products commercially available that can be abused through nasal inhalation. This is an essential step forward for Ensysce to bring PF614 to market and provide safer options for pain management for alleviating patient suffering, an important unmet need."
The PF614-103 study examined the pharmacokinetic and pharmacodynamic (e.g., Maximum Drug Liking and Take Drug Again) of PF614 (100 mg) versus crushed oxycodone (40 mg) and placebo, all administered by inhalation in 26 recreational drug users. The primary outcome measure is the maximum effect (Emax) for ‘Drug Liking.'
PF614 is a TAAPTM product designed as a delayed onset oxycodone prodrug. TAAPTM chemical modification inactivates the active ingredient in Ensysce's opioids products including PF614. This provides abuse deterrence, resistance to manipulation and other forms of recreational drug abuse, while providing a high degree of pain relief for those in severe pain. This study builds on the safety and pharmacokinetic results already seen in the prior clinical studies and improves the understanding of how PF614 compares to currently available commercial products.
