Corporate Update Call to be Held Tuesday, May 17, 2022

SAN DIEGO, CA / ACCESSWIRE / May 12, 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 and performance focused on reducing abuse and overdose, today reported financial results for the first quarter 2022.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce, commented, 'The first few months of 2022 are off to an exciting start, evident in the most recent clinical results from trials PF614-102 and PF614-MPAR-101. As we progress on our studies and clinical trials, we are closer to realizing our mission - providing abuse and overdose protection where needed. I look forward to our upcoming corporate update call next week to discuss the recent results from the trials, especially regarding the longer-lasting profile of PF614 and the encouraging initial data from our overdose protection study. Additionally, we expect the Bioequivalence (BE) trial data of our TAAP™ opioid, PF614, to be available prior to the end of the second quarter, positioning PF614 as our first commercial candidate and demonstrating progress towards our goal to bring a unique pipeline of products to the market.'

TAAP^TM (Opioid Abuse Deterrent Program) Updates

• On May 5, 2022, the Company announced clinical trial results from trial PF614-102 confirming the safety and longer-lasting profile of PF614 versus Oxycontin.
• 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. 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 serious treatment emergent adverse events recorded.
• The second part of the PF614-102 study, the bioequivalence (BE) arm, continues to be analyzed and as reported previously, we anticipate that this BE data will be available by the end of the second quarter of 2022. The Company believes that the data will support the 505(b)(2) regulatory path for clinical development of PF614, an abbreviated pathway to FDA approval.
• Human abuse liability (HAL) studies to determine labeling claims for PF614 are scheduled to initiate in the second quarter of 2022.
• PF614 is designed using the abuse protective platform TAAP™, Trypsin Activated Abuse Protection, a chemical modification which inactivates the active ingredient in Ensysce's opioid products, including PF614, until swallowed and exposed to the enzyme trypsin in the digestive system. Our TAAP™ platform, which we believe provides abuse protection and resistance to manipulation and other forms of recreational drug abuse, should also control the rate of release of the active opioid.

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

• On May 5, 2022, the Company announced initial results from trial PF614-MPAR-101, providing first human data showing the potential for overdose protection with MPAR, Multi-Pill Abuse Resistance.
• 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.
• The study is continuing with additional subjects enrolling to receive PF614 and trypsin inhibitor nafamostat in various combinations through the third quarter of 2022. Safety and pharmacokinetic results are expected by the end of the third quarter 2022.

Financial Results

• Cash - Cash and cash equivalents were $8.4 million as of March 31, 2022, as compared to $12.3 million at December 31, 2021. Cash used in operating activities for the first quarter of 2022 totaled $3.4 million, an increase from $0.5 million in the first quarter of 2021 that primarily resulted from the clinical advancement of our product candidates and increased costs related to operating as a public company.
• Federal Grants - Funding from federal grants was $0.6 million for the first quarter of 2022 compared to $0.3 in the comparable year ago quarter. Funding increased by $0.4 million under the MPAR Grant, offset by a decrease of $0.1 million under the OUD Grant, due to the timing of research activities eligible for funding.
• Research & Development Expenses - R&D expenses were $3.1 million for the first quarter of 2022 compared to $0.3 million in the comparable year ago quarter. The increase was primarily the result of increased external research and development costs related to preclinical and clinical programs for PF614 and PF614-MPAR™.
• General & Administrative Expenses - G&A expenses were $2.3 million for the first quarter of 2022 compared to $0.5 million for the same period in 2021. The increase was primarily a result of increased expenses related to operating as a public company, including legal and accounting fees and director and officer insurance expenses.
• Other Income (Expense) - Total other income (expense), was income of $3.9 million in the first quarter of 2022 and expense of $0.4 million in the first quarter of 2021. The income in the 2022 period is due to non-cash valuation adjustments of current obligations of the Company. The 2021 expense primarily reflects non-cash interest expense on notes that were converted on June 30, 2021.
• Net Income (Loss) - Net loss for the first quarter of 2022 was $1.0 million compared to net loss of $0.9 million for the comparable year ago period. As we are a clinical stage biotech company, our research and development of, and regulatory approvals for, our product candidates are expected to continue, resulting in expected losses for the foreseeable future.

Additional Company Highlights

• On February 8, 2022, the Company added further depth to its Board of Directors with the appointment of Lee Rauch.
• On April 18, 2022, the Company announced the appointment of Dr. Nily Osman as Chief Medical Officer.
