Ensysce Biosciences is a clinical-stage biotech developing abuse-resistant and overdose-protective opioid prodrugs, including PF614 and PF26810, for pain management, addiction, and overdose prevention.

PF614, a clinical-stage opioid from Ensysce's TAAP platform, is designed to treat severe pain with abuse prevention features and is currently in Phase 3 trials assessing its safety and efficacy.
In November 2025, Ensysce Biosciences announced it had received positive written feedback from the U.S. Food and Drug Administration (FDA) that aligned with the company's proposed commercial manufacturing strategy for its lead drug candidate, PF614. This event was highly notable as it significantly de-risked the company's path to market by validating its manufacturing, chemistry, and controls (CMC) approach, a critical step required for a New Drug Application (NDA) submission.
Ensysce Biosciences achieved a major milestone by initiating enrollment in its pivotal Phase 3 clinical trial for PF614, its lead next-generation, abuse-deterrent opioid. This final stage of clinical development is designed to validate PF614's effectiveness in managing severe pain and is a critical step toward a potential New Drug Application and commercialization.
