Ensysce Biosciences (NASDAQ:ENSC) has received a U.S. Patent Notice of Allowance for PF9001, a novel treatment for opioid use disorder (OUD). The patent covers both composition of matter and method of use claims for enzyme-cleavable methadone prodrugs.
The innovative medication utilizes Ensysce's TAAP and MPAR technologies for abuse deterrence and overdose protection. PF9001 represents an advancement over traditional methadone treatment, showing reduced potential for cardiotoxicity and offering overdose protection. The drug demonstrates promise for once-daily dosing with prolonged and predictable effects.
The research, supported by the National Institute on Drug Abuse under Award Number UG3DA050271, aims to address limitations of current OUD treatments, particularly concerns over cardiac side effects, respiratory depression, and overdose risks.
Ensysce Biosciences (NASDAQ:ENSC) has announced positive results from Part 1 of its second clinical trial evaluating PF614-MPAR for opioid overdose protection. The study demonstrated that their combined TAAP and MPAR technologies can effectively deliver pain relief while protecting against overdose risks.
The trial confirmed that a 100 mg dosage of PF614-MPAR successfully delivers oxycodone for severe pain treatment while providing overdose protection at higher-than-prescribed doses. When subjects took three or more doses simultaneously, the maximum oxycodone release (Cmax) was reduced compared to unprotected PF614, with greater protection observed at five doses. No unexpected adverse events were reported.
The study will proceed with Part 2 to examine food effects and Part 3 to evaluate repeat dosing. PF614-MPAR is currently the only opioid product with FDA's Breakthrough Therapy designation. The company plans to discuss the complete analysis with the FDA regarding full development plans for commercialization.
