Ensysce Biosciences Inc. reported that board member Dr. Curtis Rosebraugh resigned from its Board of Directors, effective April 1, 2026. He also stepped down from the Board’s Nominating and Corporate Governance Committee. His written resignation notice is included as Exhibit 17 to the report.
Ensysce Biosciences is a clinical-stage pharmaceutical company developing abuse-resistant and overdose-protective opioid pain therapies using its TAAP and MPAR platforms. Lead drug PF614, an extended-release oxycodone prodrug, has completed multiple Phase 1 trials and human abuse potential studies, and a pivotal Phase 3 post-surgical pain trial began enrollment in December 2025.
Combination candidate PF614-MPAR, which adds nafamostat for overdose protection, has shown reduced oxycodone exposure in simulated overdose settings and received FDA Breakthrough Therapy designation in January 2024. The company highlights substantial ongoing losses, a need for significant additional funding, reliance on PF614 and PF614-MPAR, Nasdaq delisting risk, and extensive regulatory and intellectual property uncertainties.
Ensysce Biosciences reported fourth quarter and full year 2025 results alongside clinical and regulatory progress for its opioid safety pipeline. The company advanced lead pain candidate PF614 into a pivotal Phase 3 post‑surgical pain trial and continued development of PF614‑MPAR, which has FDA Breakthrough Therapy designation for its overdose‑protection technology.
PF614‑301 Phase 3 enrollment is underway, and the FDA provided supportive feedback for PF614‑MPAR, including potential use of a streamlined 505(b)(2) pathway and overdose‑protection labeling. Ensysce also expanded its intellectual property, with a new U.S. patent on MPAR® technology extending protection to 2042 and a European notice of allowance for an amphetamine prodrug patent.
Financially, federal grant funding was $5.1 million in 2025, while research and development expenses rose to $10.4 million and general and administrative costs were $4.9 million. Net loss attributable to common stockholders increased to $10.2 million for 2025, with fourth quarter loss of $2.8 million. Cash and cash equivalents were $4.3 million at December 31, 2025, supported by $8.7 million of net cash provided by financing activities. As a clinical‑stage biotech, the company expects continued losses as it invests in late‑stage trials and pipeline growth.
Ensysce Biosciences announced that board member Lee Rauch resigned from the Board of Directors effective March 24, 2026. She previously served on the Audit and Compensation Committees and chaired the Nominating and Corporate Governance Committee. Rauch’s resignation follows her disagreement with new retention and severance arrangements for certain managers and the Chief Financial Officer.
The company is considering strategic alternatives and approved three‑month severance packages for three managers and extended CFO Mr. Humphrey’s retention package from six to nine months. These protections apply if they are not retained in a strategic transaction or for one year afterward and provide releases of claims and reaffirmed restrictive covenants. The total estimated cost of these measures is about $205,475. Rauch voted against the packages and had expressed other disagreements with board actions before resigning.
Ensysce Biosciences, Inc. filed a Certificate of Correction with the State of Delaware on March 18, 2026 to fix a scrivener’s error in its Certificate of Designation for Series B Preferred Stock, which is part of its Certificate of Incorporation. The full correction text is provided in Exhibit 3.1.
Ensysce Biosciences received a Nasdaq notice that its common stock no longer meets the exchange’s minimum bid price requirement, because the share price has closed below $1.00 for 30 consecutive business days. This puts the company at risk of eventually losing its Nasdaq listing.
The company has 180 calendar days, until August 24, 2026, to regain compliance by having its stock close at or above $1.00 for at least ten consecutive business days. The notice does not immediately affect trading, and the shares continue to trade on the Nasdaq Capital Market under the symbol ENSC while the company monitors its bid price and evaluates options.
Ensysce Biosciences, Inc. held its annual stockholder meeting on January 7, 2026. Stockholders approved, for purposes of Nasdaq Listing Rule 5635(d), the full issuance of shares of common stock and the exercise of warrants for common stock issued to an investor. They also approved an amendment to the Ensysce Biosciences, Inc. Amended and Restated 2021 Omnibus Incentive Plan, increasing the total number of shares that may be issued under the plan from 121,457 shares to 721,457 shares.
Stockholders elected two Class I directors, William Chang and Lee Rauch, to terms expiring at the 2028 annual meeting. In addition, they ratified the appointment of Baker Tilly US, LLP as the company’s independent registered public accounting firm for the fiscal year ending December 31, 2025. A fifth proposal to adjourn the meeting, if needed, was included in the proxy materials but was not submitted to a vote.
Ensysce Biosciences, Inc. is asking stockholders to approve several key items at its virtual annual meeting on December 23, 2025. The centerpiece is approval, under Nasdaq Listing Rule 5635(d), of the full issuance of common stock tied to a November 2025 financing, including preferred stock that converts into common shares and warrants with a $2.50 exercise price. If all preferred shares and 880,000 warrants are converted and exercised at current terms, the institutional purchaser would hold 2,640,000 common shares, or 75% of shares outstanding on a pre-transaction basis and 43% on a post-transaction basis using 6,181,262 shares. Ensysce also seeks to amend its 2021 Omnibus Incentive Plan to raise the share reserve from 121,457 to 721,457 shares, roughly 20% of outstanding stock, elect two Class I directors, ratify its auditor, and approve a possible adjournment to solicit more proxies.
