PF614-MPAR Progressing to Phase 1b Study to Verify Both Overdose Protection and Effective Delivery of Oxycodone
Opioid Use Disorder Program Advances with Selection of PF9001 as Lead Drug Candidate
PF614 Phase 3 Protocol Being Finalized for Submission to FDA

SAN DIEGO, CA / ACCESSWIRE / August 14, 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 reported financial and operational results for the second quarter ended June 30, 2024.

Dr. Lynn Kirkpatrick, Chief Executive Officer of Ensysce, commented, "Our FDA-designated Breakthrough Therapy product candidate, PF614-MPAR, is a game-changer for Ensysce as we progress to a second clinical trial, PF614-MPAR-102. We have re-engaged Quotient Sciences to prepare our Phase 1b protocol which will utilize their Translational Pharmaceutics® platform to manufacture and test the PF614-MPAR drug product to expedite the completion of this clinical study.

Additionally, an important breakthrough emerged in our opioid use disorder (OUD) program with the identification of our lead candidate, PF9001. Our OUD program is designed to provide a safer product for those suffering from OUD and is supported by an ongoing multi-year National Institutes of Health (NIH) award."

Dr. Kirkpatrick concluded, "Looking ahead, with our PF614 Phase 3 clinical trial on track to initiate in the second half of this year, we are finalizing the Phase 3 protocol design and preparing for site selection in the coming months. The favorable data generated from our prior PF614 clinical studies verified that PF614 delivers oxycodone in a manner equivalent to a commercially available opioid and provides pain relief with reduced abuse potential. Our goal is to provide safe and effective TAAP^TM and MPAR® products and differentiate PF614 and PF614-MPAR from the current slate of extended-release opioid analgesics, as evidenced from the data we have generated over the last year."

TAAP^TM (Opioid Abuse Deterrent Program) Update

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. Regulatory submissions and meetings were held in early 2024 and a Phase 3 trial is planned to initiate in the second half of 2024.

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

PF614-MPAR is a combination product of the TAAP^TM 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, leading to the FDA's recognition and Breakthrough Therapy designation. The Company's upcoming Phase 1b study, PF614-MPAR-102, will test multiple PF614-MPAR drug products to verify both overdose protection and effective delivery of oxycodone across a dosage range.

Opioid Use Disorder (OUD) Program Update

In June, the Company achieved a critical milestone in the OUD program with the selection of lead drug candidate PF9001, designed to provide a safer and more effective way to help those suffering from the effects of opioid use. PF9001, designed with the application of Ensysce's TAAP^TM platform to reduce the abuse profile, has demonstrated a lower potential for cardiovascular side effects associated with traditional methadone OUD treatments. The program is continuing to advance to Investigational New Drug (IND) enabling studies. In coordination with advancement of the OUD program, the Company announced an agreement with Purisys LLC to scale the manufacture of PF9001. This OUD work has been supported by a multi-year Helping to End Addiction Long-Term (HEAL) award of up to $15 million granted by the NIH and the National Institute on Drug Abuse (NIDA).

Q2 2024 Financial Results

Cash - Cash and cash equivalents were $1.0 million as of June 30, 2024, compared to $1.1 million as of December 31, 2023.

Federal Grants - Funding under federal grants totaled to $0.2 million for the second quarter of 2024 compared to $0.5 million in the comparable year ago quarter. The difference is due to the completion of funding under the MPAR grant in December 2023.

Research & Development Expenses - R&D expenses were $0.9 million for the second quarter of 2024 compared to $1.6 million for the same period in 2023. The decrease of $0.7 million was primarily due to reduced external research and development costs related to clinical and pre-clinical programs for PF614 and PF614-MPAR.

General & Administrative Expenses - G&A expenses were $1.2 million in the second quarter of 2024, generally in line with $1.1 million for the second quarter of 2023.

Other Income (Expense) - Total other income (expense), net, was an expense of approximately $12,000 for the second quarter of 2024 compared to income of approximately $55,000 for the same period of 2023. The changes in other expenses were primarily due to interest expense and non-cash fair value adjustments for warrants.

Net Loss - Net loss attributable to common stockholders for the second quarter of 2024 was $2.0 million compared to $2.2 million for the second quarter of 2023. 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.
