Ensysce Biosciences Reports Second Quarter 2023 Financial Results

~ Progression Toward Full Phase 3 Evaluation of PF614 with Recently Announced IRB Approval of Key Study Protocol ~

SAN DIEGO, CA / ACCESSWIRE / August 11, 2023 / Ensysce Biosciences, Inc. ("Ensysce" or the "Company") (NASDAQ:ENSC), a clinical-stage company applying transformative chemistry to improve prescription drug safety, today reported financial results for the second quarter of 2023.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce, commented, "The recently announced IRB approval of the PF614-201 protocol gives us confidence in the momentum we have achieved to date, bringing us closer to our Phase 3 evaluation of PF614. We believe the unique chemistry we have designed around opioids will ultimately lead to a new generation of pain products to alleviate the suffering of those who experience severe pain. We expect our goal to develop both PF614 and PF614-MPAR and expand the use of our two core technologies will be advanced by the recently announced engagement of Alacrita Consulting to explore partnering and licensing opportunities."

TAAP^TM (Opioid Abuse Deterrent Program) Updates

Our lead product, PF614, is a Trypsin-Activated Abuse Protection (TAAP^TM) extended-release oxycodone and a potential ‘next generation' analgesic for severe pain. The Company's TAAP^TM technology is designed to control release, be highly resistant to tampering and reduce abuse through a unique chemical modification. PF614's TAAP^TM modification makes it inactive until it is swallowed, following which it is activated or ‘turned on' to release oxycodone by the body's owntrypsin, an enzyme in the small intestine. Ensysce completed three clinical trials over the last year and believes it has a body of evidence showing that PF614 works as designed, is bioequivalent to OxyContin and has a good safety profile. Our most recent studies demonstrate that PF614 is less liked by recreational drug users when taken orally as compared to regular oxycodone, so we believe it is less likely to be abused.

Most recently, on August 8, 2023, the Company announced the Investigational Review Board ("IRB") approval of the PF614-201 protocol, ‘A Randomized, Double-Blind, Placebo-Controlled Crossover Study of PF614 on Analgesic Response in the Cold Pressor Test in Healthy Male Subjects.' This represents yet another key milestone for PF614 in its development pathway. The Company believes the requirement for exposure to trypsin and the chemically designed release kinetics distinguish PF614 from other marketed oxycodone drug products.

On April 3, 2023, the Company announced positive results from PF614-104, a study that evaluated the oral abuse potential of PF614. The study met all key endpoints and showed that oral administration of PF614 had significantly lower scores for "Drug Liking" and willingness to "Take Drug Again" than the oxycodone comparator. The completion of this trial, in addition to the PF614-102 and PF614-103 trials now positions PF614 for an End of Phase 2 meeting with the FDA, anticipated later this year and initiating our Phase 3 strategy in 2024.

MPAR® (Opioid Abuse Deterrent and Overdose Protection Program) Updates

PF614-MPAR is a combination product to treat severe pain, designed with overdose protection. MPAR® (Multi-Pill Abuse Resistance) reduces or ‘turns off' the release of the opioid in an overdose situation, providing the additional layer of protection to Ensysce's TAAP™ medications. We believe that MPAR® is the first technology that may reduce prescription drug overdoses stemming from oral abuse and that it can save lives. The clinical data generated over the past year shows that the MPAR® combination technology reduces release and absorption of oxycodone from PF614, specifically in an overdose situation. We are now positioned to have a meeting with the FDA to discuss the MPAR® overdose protection program and our full dose range of PF614-MPAR drug products.

On May 9, 2023, the Company announced the successful completion of overdose protection Phase 1 study, PF614-MPAR-101. The final Part B of the study examined dose escalation of PF614-MPAR and successfully showed that PF614-MPAR delivered oxycodone appropriately when one or two doses were consumed yet reduced opioid delivery when three or more doses are consumed simultaneously, in a simulated overdose situation.

We believe that the clinical results from Ensysce's programs indicate that both PF614 and PF614-MPAR represent important improvements for severe pain management, an issue that has greatly impacted the United States in recent years where access to prescriptions of these strong pain medications has been affected by the opioid crisis.

Second Quarter 2023 Financial Results

• Cash - Cash and cash equivalents were $3.8 million as of June 30, 2023, as compared to $1.4 million as of March 31, 2023. The net increase in cash primarily results from a public offering on May 12, 2023, with gross proceeds of $7.0 million before deducting placement agent fees and other offering expenses, less operating expenses for the quarter.
• Federal Grants - Funding under federal grants increased to $0.5 million for the second quarter of 2023 compared to $0.2 million in the comparable year ago quarter. The increase is due to the timing of research activities eligible for funding, particularly related to the MPAR® program.
• Research & Development Expenses - R&D expenses decreased to $1.6 million for the second quarter of 2023 compared to $5.3 million for the same period in 2022. The decrease was primarily the result of timing of external research and development costs related to clinical studies for PF614.
• General & Administrative Expenses - G&A expenses decreased to $1.1 million for the second quarter of 2023 compared to $1.9 million for the same period of 2022. The decrease was primarily due to reduced stock-based compensation and reduced costs associated with liability insurance in the 2023 period.
• Other Income (Expense) - Total other income (expense), net was income of $55,000 for the second quarter of 2023 compared to expense of $0.9 million for the same period of 2022. The change in other expenses is primarily due to non-cash fair value adjustments for convertible notes and warrants.
• Net Loss - Net loss attributable to common stockholders for the second quarter of 2023 was $2.2 million compared to $7.9 million for the second quarter of 2022. 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.
