Ensysce Biosciences Announces New Clinical Results from Trials PF614-102 and PF614-MPAR-101
Ensysce Biosciences has announced positive results from clinical trials PF614-102 and PF614-MPAR-101, demonstrating the safety and longer-lasting efficacy of PF614 compared to OxyContin. The dual study confirms PF614's potential for abuse and overdose protection, with a significantly extended half-life on Day 5 compared to OxyContin. Both studies reported no serious adverse events and limited opioid-related side effects. The company is set to host a corporate update call on May 17, 2022, to discuss these findings and future steps.
- PF614 demonstrates longer-lasting half-life (13.75 to 28.4 hours) compared to OxyContin (4.5 to 7.8 hours).
- No serious adverse events in clinical trials PF614-102 and PF614-MPAR-101.
- First human data shows PF614's potential for overdose protection with MPAR.
- None.
~ Results confirmed the safety and longer-lasting profile of PF614 versus OxyContin and provides first human data showing the potential for overdose protection with MPAR~

SAN DIEGO, CA / ACCESSWIRE / May 5, 2022 / Ensysce Biosciences, Inc. ("Ensysce" or the "Company") (NASDAQ:ENSC, OTC:ENSCW), a clinical-stage biotech company applying transformative chemistry to improve prescription drug safety and performance with a current focus on reducing abuse and overdose, today presented results from the clinical trials PF614-102 and PF614-MPAR-101 at the SMi Pain Therapeutics meeting in London, UK.
PF614-102
The multi-ascending dose study (MAD) study examined 3 dose levels of PF614, a novel TAAP prodrug of oxycodone and the Company's lead candidate in Phase 2 development for the treatment moderate to severe pain. The MAD study evaluated PF614 delivered as an oral solution or as 100 mg capsules. The healthy volunteer study was designed to evaluate the safety and pharmacokinetics of five days of treatment with twice daily doses of PF614 to equivalent doses of OxyContin, the extended-release abuse deterrent formulation of oxycodone. The results of the study show the longer-lasting half-life of PF614 versus OxyContin as seen in the prior Phase 1 single-ascending dose study of PF614 oral solution versus OxyContin. The pharmacokinetic data demonstrated that PF614 has a delayed onset and extended activity after delivery, with a time to maximal drug concentration of 5.8 hour similar to Oxycontin's 4.5 hour. A distinguishing feature of PF614 is its terminal half-life which on Day 5 ranged from 13.75 to 28.4 hour as compared to 4.5 to 7.8 hour for OxyContin. We believe this data confirms the findings from our Phase 1 study that demonstrate PF614 should provide true twice daily dosing.
The safety data for the study also showed that PF614 performed similarly to OxyContin with no test article serious adverse events recorded. Treatment emergent adverse events (TEAE) were limited and opioid related.
The second part of the PF614-102 study, the bioequivalence (BE) arm, continues to be analyzed and as reported previously it is anticipated that this BE data will be available at the end of the second quarter of 2022.
PF614-MPAR-101
PF614-MPAR-101 overdose protection study examined PF614 administered orally alone or in combination with the trypsin inhibitor nafamostat (MPAR) to healthy volunteers. This data demonstrated how the combination product PF614-MPAR could reduce the trypsin activation and reduce the release of oxycodone in a simulated overdose situation. It also demonstrated the PF614 in the systemic circulation (simulated injection) did not convert to oxycodone. We believe this is the first step to identifying the first MPAR drug product that will be marketed in the coming years.
Dr. William Schmidt, Senior VP of Clinical Development, commented, "The results of the 102 study are in-line with our expectations, and we are eager to continue making progress towards bringing our lead ‘next generation' opioid to market. The results from this clinical trial represent a critical milestone for Ensysce confirming our previous findings that were highly encouraging, and a significant step towards our mission of providing safer, effective options for doctors and patients. We were also highly enthused by the first MPAR data as it is confirmation that our approach for overdose protection is a possibility - not just a hope."
Dr. Lynn Kirkpatrick, Chief Executive Officer, added, "We believe with these study results we have added to an already strong foundation of data supporting our novel approach to delivering pain relief, and begin to realize our stated mission - providing abuse and overdose protection where needed. It is exciting to see the first human data for MPAR, and as the study progresses, we feel our solidification of a final drug product is possible. We entered 2022 with clear progress against our clinical stage pipeline and this data further positions the Company for continued successes. We look forward to reviewing the data in further detail and sharing with all Ensysce' constituents in the coming weeks, ultimately this is a step towards value creation for our shareholders."
