• Substantial Award Follows FDA Breakthrough Therapy Designation for PF614-MPAR 
• Federal Grant Funding Awarded to Date Now at $40 Million 

SAN DIEGO, CA / ACCESSWIRE / August 27, 2024 / 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 receipt of a $14 million multi-year grant from the NIH and National Institute on Drug Abuse (NIDA) for the continued development of PF614-MPAR, an abuse-deterrent opioid with overdose protection that received Breakthrough Therapy designation from the FDA in January 2024. Funding from this award will be available over a period of approximately three years, allowing for the completion of the Phase 1b clinical trial, PF614-MPAR-102. This Phase 1b study is designed to expand the product offering identified in the PF614-MPAR-101 study, the first study to verify the overdose protection of the Multi-Pill Abuse Resistance (MPAR^®) platform. Combined, the two studies will help position PF614-MPAR as the first opioid product with oral overdose protection.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce Biosciences, commented, "This non-dilutive award by NIDA is another meaningful vote of support by the federal government for the development of this novel class of opioids with overdose protection. Our initial Phase 1 study of PF614-MPAR demonstrated this approach to treat pain provides protection from taking too many pills orally. With this funding, adding to the two prior grants of over $26 million for the initial work on the MPAR and opioid use disorder (OUD) programs, Ensysce intends to quickly drive PF614-MPAR through clinical development to make its benefits available in a large market where we believe unmet need is high."

PF614-MPAR is designed to provide optimal pain relief at prescribed doses yet limit accidental or intentional overdose by ‘shutting down' opioid release if too much active drug is consumed. PF614-MPAR could herald a new class of treatment for the most severe forms of pain and could save lives, as each capsule contains built-in protection against both abuse and overdose which plague traditional opioids. Safer opioids for severe pain which protect against abuse and oral overdose are vital to address the discouraging statistics from the Centers for Disease Control of almost two overdose deaths per hour. Ensysce is forging the way to reverse this trend with two new opioids in clinical development. The MPAR^® technology may also have applications for improving drug safety beyond opioids.

About Breakthrough Therapy Designation

Breakthrough Therapy is a rarely used designation, having been granted by the FDA to fewer than 300 drugs since its introduction in 2012. It is designed to expedite the development and review of drugs that are intended to treat a serious condition where preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapies.
