Ensysce Biosciences Reports Fourth Quarter and Full Year 2023 Financial Results

Corporate Update Call to be Held Thursday, March 21, 2024 at 11:00am ET to Discuss Recent FDA Breakthrough Therapy Designation and Phase 3 Clinical Plans

SAN DIEGO, CA / ACCESSWIRE / March 15, 2024 / 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 fourth quarter and full year of 2023.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce, commented, "We are proud of the significant progress Ensysce has made in 2023 both operationally and clinically for our lead pain therapeutic, PF614, and our overdose protection product, PF614-MPAR. Our advancements were particularly instrumental in providing a foundation for our constructive end of Phase 2 meeting with the U.S. Food & Drug Administration (FDA) for PF614. We believe the FDA's guidance positioned Ensysce favorably and solidified the PF614 Phase 3 clinical study designs to initiate enrollment in the second half of 2024, ultimately reducing regulatory risks that could impede our commercialization plan. Especially encouraging was the FDA grant of Breakthrough Therapy designation to PF614-MPAR in January 2024, acknowledging its unique advantage over current opioids. Breakthrough Therapy, an exclusive designation applied to less than 300 drugs historically, offers Ensysce the opportunity to accelerate our clinical programs and go-to market plans."

"Importantly, the collective empirical data we've received from four completed clinical studies verify PF614's bioequivalence to commercially available opioids but with reduced abuse potential, and reaffirms our belief that Ensysce's PF614 will provide a "next generation" opioid family with the added value proposition of safer products with overdose protection. We have many reasons to remain optimistic on our path to regulatory approval as we advance through our Phase 3 clinical trials beginning in the second half of 2024. Progress in 2023 and early 2024 has provided further evidence that our innovative analgesics will provide prescribers and patients in severe pain with an alternative, effective option with safety advantages to address the opioid epidemic in the United States," concluded Dr. Kirkpatrick.

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 own trypsin, an enzyme in the small intestine. Ensysce recently completed a Phase 2 clinical trial for PF614, received FDA guidance on the strategy and design of its Phase 3 clinical program and expects to commence enrollment for the Phase 3 clinical trial in the second half of 2024. Ensysce believes it has a body of evidence showing that PF614 works as designed, has a good safety profile and is bioequivalent to OxyContin providing strong efficacy, yet reduced abuse potential.

As a reaffirmation of the Company's belief in the efficacy of PF614, on February 15, 2024, the Company announced the online publication of its manuscript entitled, "Clinical evaluation of PF614, a novel TAAP^TM prodrug of oxycodone, versus OxyContin® in a multi-ascending dose study with a bioequivalence arm in healthy volunteers" by the open-access medical journal Clinical and Translational Science (CTS) sponsored by the American Society of Clinical Pharmacology and Therapeutics (ASCPT). The results from the two-part PF614‑102 study demonstrate a clear dose relationship between PF614 and oxycodone, which is the foundation for the FDA submission.

As previously mentioned, on January 31, 2024, the Company completed a successful End of Phase 2 meeting with the FDA regarding PF614 and received guidance on its non-clinical development approach and clinical development plans.

Instrumental to the meeting was the PF614-201 study, "A Randomized, Double-Blind, Placebo-Controlled Crossover Study of PF614 on Analgesic Response in the Cold Pressor Test in Healthy Male Subjects" that concluded in December 2023. This study measured the time-of-onset of pain-relief in healthy volunteers and showed that Ensysce's TAAP^TM chemical approach delivers effective analgesia. This study was a meaningful component of the Company's Phase 3 clinical protocol design and a driver of the positive outcome with the FDA.

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

PF614-MPAR is a combination product of the TAAP prodrug PF614 with a trypsin inhibitor, designed to treat severe pain while providing overdose protection. MPAR® (Multi-Pill Abuse Resistance) reduces or ‘turns off' the release of the opioid to prevent an overdose, providing an additional layer of protection to Ensysce's TAAP™ medications. Over the past year, clinical data demonstrated that the MPAR® technology reduces release and absorption of oxycodone from PF614 when consumed in more than a prescribed dose.

Importantly, in January 2024, Ensysce received notice from the FDA that it had granted Breakthrough Therapy designation for PF614-MPAR, acknowledging the potential impact of the innovative MPAR® overdose protection technology. Breakthrough Therapy is an elite designation that expedites the development and review of drugs that are intended to treat a serious condition where the drug may demonstrate substantial improvement over available therapies.

In February, the Company received additional productive guidance from the FDA to aid the design of our PF614-MPAR programs to efficiently move toward a new drug application (NDA) submission and approval to bring this innovative drug to market.

Financial Results

Cash - Cash and cash equivalents were $1.1 million as of December 31, 2023, as compared to $1.5 million as of September 30, 2023. After year end, the Company received cash proceeds of $2.1 million from the exercise of warrants, originally issued in the fourth quarter of 2023, to purchase 1.3 million shares of common stock. Additionally, in February 2024, the Company received gross proceeds of $4.7 million, prior to deducting placement agent fees and offering expenses, from the exercise of warrants to purchase 3.6 million shares of common stock originally issued in May 2023.

Federal Grants - Funding under federal grants totaled to $0.5 million for the fourth quarter of 2023 compared to $1.4 million in the comparable year ago quarter. For the full year of 2023, funding from federal grants was $2.2 million compared to $2.5 million for the full year of 2022. The decreases are due to the timing of research activities eligible for funding, particularly relative to the MPAR® program.

Research & Development Expenses - R&D expenses were $2.2 million for the fourth quarter of 2023 compared to $6.4 million for the same period in 2022. For the full year of 2023, R&D expenses were $7.6 million compared to $19.8 million for the full year of 2022. The decreases were primarily the result of reduced external research and development costs related to the clinical programs for PF614 and PF614-MPAR, particularly regarding bioequivalence and human abuse potential studies for PF614.

General & Administrative Expenses - G&A expenses were $1.4 million in the fourth quarter of 2023, a slight increase compared to $1.2 million for the same period of 2022. For the full year of 2023, G&A expenses were $5.4 million, a decrease compared to $6.9 million for the full year of 2022. The quarterly increase from the same prior year period was primarily a result of higher non-cash stock-based compensation, while the full year decrease resulted from reduced consulting, legal, liability insurance and employee bonus expenses.

Other Income (Expense) - Total other income (expense), net was an expense of $0.3 million for the fourth quarter of 2023 compared to income of $0.7 million for the same period of 2022. For the full year, total other income (expense), net was income of $91,912 in 2023 compared to income of $14,410 in 2022. The changes in other expenses were primarily due to non-cash fair value adjustments for convertible notes and warrants.

Net Loss - Net loss attributable to common stockholders for the fourth quarter of 2023 was $3.5 million compared to $5.5 million for the fourth quarter of 2022. For the full year of 2023, net loss was $10.6 million compared to $25.1 million for the full year 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.
