Ondansetron Hydrochloride

Confirmed relative bioavailability to the reference standard, dose proportional increases in pharmacokinetic exposure, and no food effect Marks final study needed for the upcoming FDA meeting for the Phase 3 study design and ongoing partnership discussions Continued excellent safety and tolerability findings, consistent with extensive human use experience with ondansetron GLEN ALLEN, Va., Nov. 14, 2024 (GLOBE NEWSWIRE) -- Adial Pharmaceuticals, Inc. (NASDAQ: ADIL) ("Adial" or the "Company"), a clinical-stage biopharmaceutical company focused on developing therapies for the treatment and prevention of addiction and related disorders, announced 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). This data will 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 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. Cary Claiborne, President and Chief Executive Officer of Adial commented, "Completion of this study achieves our goal to obtain the data we needed to design a more precise and informed Phase 3 trial protocol, including evaluating the optimal dosing regimen to maximize the efficacy and safety of AD04 in patients with AUD. Its completion is in accord with previous guidance provided by the FDA and is intended to enhance the likelihood of success in our upcoming Phase 3 trial. This relatively short and low-cost study was a key element of our strategy to advance ongoing partnership discussions. Additionally, the study will provide data necessary to support an application for approval of AD04 under a 505(b)(2) regulatory pathway with the FDA. We plan to engage with the FDA during Q4 2024 with the results of this pharmacokinetics study and obtain feedback which will assist with the AD04 Phase 3 study program. This meeting is an important next step to further advancing AD04 towards regulatory approval." About AD04AD04 (0.33mg ondansetron taken orally twice daily) acts upon the 5HT3 pathway and is thought to reduce alcohol craving. This mode of action is distinct from, but complimentary to, the currently approved therapies for AUD. Post-hoc analyses of Adial's prior clinical studies have indicated that patients with mutations in the 5HT3 receptor experience substantial and clinically meaningful reductions in alcohol consumption. The specific mutations that appear to respond to AD04 are single nucleotide polymorphisms (SNPs) on rs1150226-AG ("AG") or rs1176713-GG ("GG") genotypes in the gene that encodes the 5-HT3A receptor subunit. These genes are thought to affect the binding of AD04 to the 5HT3 receptor and its function. Furthermore, in both previous clinical trials, AD04 had similar adverse events to placebo, which further supports that it is likely to be extremely safe and tolerable. Adial has already developed a companion diagnostic test (CDx) to identify the specific genotypes that benefit from AD04. This test was used in its Phase 3 ONWARD study, will be used in future clinical studies, and will be commercially available at the time of AD04's launch. About Adial Pharmaceuticals, Inc.Adial Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development of treatments for addictions and related disorders. The Company's lead investigational new drug product, AD04, is a genetically targeted, serotonin-3 receptor antagonist, therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in heavy drinking patients and was recently investigated in the Company's ONWARD™ pivotal Phase 3 clinical trial for the potential treatment of AUD in subjects with certain target genotypes identified using the Company's companion diagnostic genetic test. ONWARD showed promising results in reducing drinking in heavy drinking patients, and no overt safety or tolerability concerns. AD04 is also believed to have the potential to treat other addictive disorders such as Opioid Use Disorder, gambling, and obesity. Additional information is available at www.adial.com.

(Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced that the Company has been selected to further elaborate on opaganib's[1] potential in a presentation to U.S. government representatives at the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense's (JPEO-CBRND) "Host Directed Therapeutics Industry Day". The meeting is scheduled to take place October 29-30, 2024, at the United States Patent and Trademark Office in Alexandria, VA. The JPEO-CBRND manages U.S. government investments in chemical, biological, radiological, and nuclear (CBRN) defense equipment and medical countermeasures (MCMs). The JPEO-CBRND mission is to provide integrated, layered, chemical, biological, radiological, and nuclear defense capabilities to the Joint Force across combined Joint all-domain operations. Based on reviews, feedback, and discussion, the judges selected for presentation those therapeutics that demonstrated capability in the prophylaxis, post-exposure prophylaxis, and treatment of exposure to viruses, bacteria and toxins. "Opaganib is already the subject of multiple ongoing collaborations with several U.S. government agencies. However, selection for presentation at this important governmental investment event provides a significant opportunity to highlight the growing body of evidence in support of opaganib's potential as an oral, host-directed, broad-acting viral, chemical and nuclear countermeasure ," said Guy Goldberg, RedHill's Chief Business Officer. About Opaganib (ABC294640) Opaganib, a proprietary investigational host-directed and potentially broad-acting drug, is a first-in-class, orally administered sphingosine kinase-2 (SPHK2) selective inhibitor with anticancer, anti-inflammatory and antiviral activity, targeting multiple potential indications, including several cancers, diabetes and obesity-related disorders, gastrointestinal acute radiation syndrome (GI-ARS), Sulfur Mustard exposure, COVID-19, Ebola and other viruses as part of pandemic preparedness. Opaganib's host-directed action is thought to work through the inhibition of multiple pathways, the induction of autophagy and apoptosis, and disruption of viral replication, through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SPHK2, DES1 and GCS). Several U.S. government countermeasures and pandemic preparedness programs have selected opaganib for evaluation for multiple indications, including Acute Radiation Syndrome (ARS), Ebola virus disease and others. Funding bodies include the Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. government Department of Health & Human Services' National Institutes of Health and the Administration for Strategic Preparedness and Response's (ASPR) Center for Biomedical Advanced Research and Development Authority (BARDA). Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A and Ebola. Opaganib delivered a statistically significant increase in survival time when given at 150 mg/kg twice a day (BID) in a United States Army Medical Research Institute of Infectious Diseases (USAMRIID) in vivo Ebola virus study, making it the first host-directed molecule to show activity in Ebola virus disease. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc.), significantly improving potency while maintaining cell viability, in a U.S. Army-funded and conducted in vitro Ebola virus study. Being host-targeted, and based on data accumulated to date, opaganib is expected to maintain effect against emerging viral variants. In prespecified analyses of Phase 2/3 clinical data in hospitalized patients with moderate to severe COVID-19, oral opaganib demonstrated improved viral RNA clearance, faster time to recovery and significant mortality reduction in key patient subpopulations versus placebo on top of standard of care. Opaganib has demonstrated its safety and tolerability profile in more than 470 people in multiple clinical studies and expanded access use. Data from the opaganib global Phase 2/3 study was published in Microorganisms. Opaganib has received several orphan-drug designations from the FDA in oncology and other diseases and has undergone studies in advanced cholangiocarcinoma (Phase 2a) and prostate cancer. Opaganib also has a Phase 1 chemoradiotherapy study protocol ready for FDA-IND submission. Opaganib has also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.
