Ondansetron Hydrochloride

Study intended to optimize design elements needed for the upcoming US Pivotal Phase 3 studies and support ongoing partnership discussions Topline results expected in early Q4 2024 June 05, 2024 -- 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 the first patient has been dosed in a pharmacokinetics study of AD04, the Company’s lead investigational genetically targeted, serotonin-3 receptor antagonist, therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in heavy drinking patients (defined as Cary Claiborne, President and Chief Executive Officer of Adial commented, “Dosing our first patient is an important milestone, marking the beginning of clinical activity in this previously planned and pre-budgeted study. Our goal is to obtain data we need 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. Completion of this study 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 is also a key element of our strategy to advance ongoing partnership discussions. The study will also provide data necessary to support an application for approval of AD04 under a 505(b)(2) regulatory pathway with FDA. Looking ahead, we plan to engage with the FDA in Q4 2024 to discuss the results of this pharmacokinetics study and obtain feedback to refine the Phase 3 study design. This meeting will help establish the final protocol and ensure that it aligns with FDA expectations, further advancing AD04 towards regulatory approval.” The pharmacokinetics study will involve two cohorts conducted consecutively and is expected to be completed in early Q4 2024. The single-center, relative bioavailability, open-label study will enroll up to 30 healthy adult volunteers and compare the pharmacokinetic profile of AD04 when administered as an oral dose taken twice daily of 0.33 mg with or without food against a reference standard product. This study will provide valuable information on the pharmacokinetic properties of AD04. The company expects to report topline results in early Q4 2024. AD04 (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, demonstrating that it is 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. 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.

New Chinese patent notice of allowance issued covering opaganib in combination with immune checkpoint inhibitors (ICIs) as a method of inducing an anti-cancer immune response [1]. Provides protection for opaganib's potential use in combination with a range of approved and in-development (ICIs) across a growing range of indications [2] through 2040 ICIs have become a cornerstone in cancer treatment, having been hailed as a major breakthrough by oncologists, with the global ICI market expected to exceed $100 billion by 2028, including Merck's Keytruda (pembrolizumab) and BMS' Yervoy (ipilimumab) [3] Opaganib, a host-directed and potentially broad acting twice-daily oral, small molecule with a demonstrated safety & efficacy profile, is in development for multiple oncology, viral and inflammatory indications, including COVID-19, Ebola, acute respiratory distress syndrome (ARDS) and two U.S. government-sponsored countermeasures programs for Acute Radiation Syndrome (ARS) and Sulfur Mustard exposure TEL-AVIV, Israel and RALEIGH, N.C., June 3, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the issue of a new Chinese patent notice of allowance for opaganib[4] in combination with immune checkpoint inhibitors (ICIs) as a method of inducing an anti-cancer immune response, providing protection for opaganib's potential use with a range of approved and in-development immune checkpoint inhibitors (ICIs) across a growing range of indications through 2040. The patent will be issued by the Chinese National Intellectual Property Administration (CNIPA) (Chinese Patent Application No.: 202080013805.3 issued May 24, 2024). "ICIs have become a cornerstone in cancer treatment, having been hailed as a major breakthrough by oncologists, with the global ICI market expected to exceed $100 billion by 2028, including Merck's Keytruda (pembrolizumab) and BMS' Yervoy (ipilimumab)," said Guy Goldberg, RedHill's Chief Business Officer. "This exciting new patent is based on compelling data from a range of in vivo experiments showing significant improvements in outcomes in combination with selected ICIs. China has been a world leader in embracing ICI-based therapy[5] and this is an important addition to the strong patent portfolio protecting opaganib." 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 diseases, including prostate cancer and cholangiocarcinoma (bile duct cancer), 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). Opaganib has been selected for evaluation by two U.S. government countermeasures programs for Acute Radiation Syndrome (ARS) and Sulfur Mustard exposure, both funded by the NIH: The Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the HHS National Institutes of Health, for the nuclear medical countermeasures (MCM) product development pipeline selected opaganib for development as a potential treatment for Acute Radiation Syndrome (ARS); and the Chemical Medical Countermeasures (Chem MCM) Program and Chemical Countermeasures Research Program (CCRP), managed respectively by the Administration for Strategic Preparedness and Response (ASPR) / Biomedical Advanced Research and Development Authority (BARDA) and NIH/NIAID selected opaganib for evaluation as a potential medical countermeasure (MCM) against Sulfur Mustard exposure. 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 medRxiv. Opaganib has received Orphan Drug designation from the FDA for the treatment of cholangiocarcinoma 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.
