Corporate Update Call to be Held Wednesday, November 16, 2022

SAN DIEGO, CA / ACCESSWIRE / November 14, 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 reported financial results for the third quarter of 2022.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce, commented, "We remain focused on progressing our clinical development plans for our programs and achieving each milestone we have identified. I could not be more pleased with the recently reported positive topline results from our human abuse potential (HAP) study for intranasal administration of PF614. These results were in-line with our expectations and importantly, consistent with the unique properties of PF614 as well as prior findings that we believe demonstrate PF614 will provide advantages over currently marketed products. The highly significant results from this study represent a major accomplishment towards our mission of reducing abuse and overdose, ultimately enhancing drug safety."

Dr. Kirkpatrick continued, "Additionally, we were very happy to provide today's announcement regarding the written guidance we received from the FDA which indicated that a development program for PF614 in acute pain may be appropriate. As a result of this FDA guidance, we believe the non-clinical program for PF614 will be significantly shortened for acute pain. We are pleased we can develop PF614 for acute pain while we also continue with our chronic pain development pathway."

TAAP^TM (Opioid Abuse Deterrent Program) Updates

PF614 is the first product in a new class of analgesia, a "Trypsin-Activated Abuse Protection" (TAAP^TM) oxycodone product. The Company's TAAP^TM technology is designed to be highly resistant to tampering and abuse and is a unique chemical modification creating a new generation of opioid pain products as compared to traditional Abuse Deterrent Formulations (ADFs). TAAP™ controls or "turns on" the release of the active ingredient in PF614 providing abuse deterrence.

• On October 31, 2022, the Company announced positive topline results from a human abuse potential (HAP) study, PF614-103, with intranasal administration of PF614 as compared to crushed oxycodone or placebo. PF614 demonstrated significantly reduced "drug liking," the primary endpoint, when compared to intranasal crushed immediate-release oxycodone.
• On October 28, 2022, the Company announced first subjects dosed in its second HAP study, PF614-104, comparing oral administration of PF614 versus oxycodone or placebo. Data from this study is expected in early 2023. These HAP studies are intended to support abuse-deterrent labeling upon final approval of PF614.
• On July 27, 2022, the Company announced positive date from a bioequivalence (BE) study PF614-102 of its novel TAAP™ opioid PF614 compared to OxyContin which the company believes will support the substitution of PF614 for OxyContin in the market. The Company believes that the BE data from this study will also support the 505(b)(2) regulatory path for clinical development of PF614, an abbreviated pathway to FDA approval. This pathway allows reference to available safety and clinical data from an approved product, and the BE data established by this study will move PF614 closer to registration.

MPAR^TM (Opioid Abuse Deterrent and Overdose Protection Program) Updates

PF614-MPAR™ is a combination product designed to have overdose protection along with the abuse protection of TAAP™. MPAR™ (Multi-Pill Abuse Resistance) turns off the release of the opioid in an overdose situation, providing the additional layer of protection to Ensysce's TAAP™ pain medications.

• On August 31, 2022, the Company announced a partnership with Quotient Sciences on the Development and Clinical Testing of PF614-MPAR^TM. Quotient Sciences is currently using its integrated Translational Pharmaceutics® platform to identify a PF614-MPAR combination that allows conversion into oxycodone within the prescribed dose range but reduces conversion to oxycodone at higher than prescribed dose levels in an overdose scenario.
  • On June 27, 2022, the Company announced its notice of award for the 4^th year of funding for its MPAR™ platform to support the final part of the ongoing clinical trial PF614-MPAR-101. The amount awarded was $2.8 million and this brings total funding from NIDA under this grant to $10.8 million.

Financial Results

• Cash - Cash and cash equivalents were $4.5 million as of September 30, 2022, as compared to $3.7 million as of June 30, 2022.
• Federal Grants - Funding from federal grants was $0.3 million for the third quarter of 2022 compared to $1.2 million in the comparable year ago quarter. The decrease is a result of timing of pre-clinical and clinical activities for the MPAR program.
• Research & Development Expenses - R&D expenses were $4.8 million for the third quarter of 2022 compared to $1.7 million in the comparable year ago quarter. The increase in expenses results from increased pre-clinical and clinical activities for PF614.
• General & Administrative Expenses - G&A expenses were $1.7 million for the third quarter of 2022 compared to $16.4 million for the same period in 2021. The decrease in expenses is largely attributable to significant non-cash expenses recorded in the prior year period related to the valuation of warrants issued.
• Other Income (Expense) - Total other income (expense) was expense of $3.7 million in the third quarter of 2022 and expense of $0.3 million in the third quarter of 2021. The change in other expenses is primarily due to non-cash fair value adjustments for convertible notes and warrants.
• Net Loss - Net loss for the third quarter of 2022 was $9.9 million compared to net loss of $17.2 million for the comparable year ago period. As a clinical stage biotech company, our continued research and development efforts toward regulatory approvals for our product candidates are expected to result in losses for the foreseeable future.
