Item 7.01. Regulation FD Disclosure.

On November 14, 2024, Adial Pharmaceuticals, Inc. (the “Company”) issued a press release announcing that it has completed a pharmacokinetics (PK) study of AD04, the Company’s lead investigational genetically targeted, serotonin-3 receptor antagonist, and therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in heavy drinking patients (defined as less than 10 drinks/drinking day).

The study, a single-center, relative bioavailability, open label study, enrolled a total of 30 healthy adult volunteers in two cohorts. Cohort 1 (n=6) was a randomized, open-label, 2-sequence, 2-period crossover study to evaluate the PK variability of ondansetron from AD04 0.33 and 0.99mg. Cohort 2 (n=24) was a randomized, open-label, 6-sequence, 4-period crossover study to evaluate the relative bioavailability of the AD04 0.33mg tablet to a marketed ondansetron 4mg tablet, dose proportionality of ondansetron PK between AD04 0.33 and 0.99mg, and the effect of food on the bioavailability of ondansetron administered as the AD04 0.33mg tablet. The results of this study showed that, as a result of the lower dose, AD04 0.33mg delivered lower ondansetron PK exposure than the marketed reference standard ondansetron 4mg tablet; ondansetron pharmacokinetic exposure increased in proportion to dose across a 3-fold AD04 dose range; and AD04 can be taken in fed or fasted states.

This data is expected to help the Company optimize study design elements needed for the upcoming Phase 3 clinical trial of AD04. Completion of this study also satisfied an FDA requirement for the upcoming Phase 3 clinical trials of AD04.

The information in this Item 7.01 and in the press release furnished as Exhibit 99.1 to this Current Report on Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended and shall not be incorporated by reference into any filing with the U.S. Securities and Exchange Commission made by the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing. The press release furnished as Exhibit 99.1 to this Current Report on Form 8-K includes “safe harbor” language pursuant to the Private Securities Litigation Reform Act of 1995, as amended, indicating that certain statements contained therein are “forward-looking” rather than historical.
