TEL-AVIV, Israel and RALEIGH, N.C., Sept. 26, 2019 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on the development and commercialization of clinical late-stage, proprietary drugs for the treatment of gastrointestinal diseases, today provided a periodic R&D update.

RHB-105 (Talicia®)1 - H. pylori Infection

The New Drug Application (NDA) for RHB-105 (Talicia) is under priority review by the U.S. Food and Drug Administration (FDA), with an assigned target Prescription Drug User Fee Act (PDUFA) action date of November 2, 2019.

RHB-204 - Pulmonary Nontuberculous Mycobacteria (NTM) Infections

In light of positive data received from the ongoing non-clinical program with RHB-204, RedHill plans to initiate pivotal Phase 3 study activities with RHB-204 for the treatment of pulmonary NTM infections in the fourth quarter of 2019, subject to additional input from the FDA. The study is intended to assess the efficacy and safety of RHB-204 and potentially support its approval as the first stand-alone, first-line treatment for Mycobacterium avium complex (MAC) disease, the most common cause of pulmonary NTM infections2.

RHB-104 - Crohn’s Disease

Following positive top-line results from the Phase 3 study with RHB-104 (MAP US study), the last patient enrolled in the open-label extension Phase 3 study with RHB-104 in Crohn’s disease (MAP US2 study) has recently completed their participation in the study. A total of 30 subjects completed 52 weeks of treatment with RHB-104 in the MAP US2 study, with top-line results expected in the fourth quarter of 2019. Following additional regulatory guidance from the FDA on the path for potential approval of RHB-104, RedHill has intensified its collaborations with leading laboratories in the field of detection of Mycobacterium avium paratuberculosis (MAP) bacteria in Crohn’s disease patients, including Baylor College of Medicine and the University of Central Florida’s (UCF) College of Medicine. As previously announced, additional FDA guidance on RHB-104’s potential path to approval is expected in the coming months.

RHB-102 (Bekinda®)1 - Acute Gastroenteritis & Gastritis and Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D)

In addition to the intended adult labeling of Bekinda for use in the treatment of nausea and vomiting associated with acute gastroenteritis and gastritis and for the treatment of IBS-D, RedHill has recently concluded a positive FDA meeting with regard to the pediatric study plans required to potentially obtain pediatric labeling for Bekinda. RedHill is advancing preparations toward a confirmatory Phase 3 study to support a potential NDA filing for Bekinda for the treatment of nausea and vomiting associated with acute gastroenteritis and gastritis.

Yeliva® (opaganib, ABC294640)1 - Cholangiocarcinoma and Additional Indications

Yeliva is being investigated in an ongoing Phase 2a study in advanced cholangiocarcinoma (bile duct cancer). The study has achieved its pre-specified efficacy goal for the first stage of the two-stage study design and is expected to complete enrollment of the full cohort by the end of the year. In addition, the National Cancer Institute (NCI) grant that was previously awarded to the Medical University of South Carolina (MUSC) to support a study with Yeliva in hepatocellular carcinoma (HCC) has been diverted to support a Phase 2 study with Yeliva in prostate cancer. The investigator-sponsored study is expected to be initiated by early 2020 at MUSC Hollings Cancer Center and will be led by Dr. Michael B. Lilly. The study is supported by several pre-clinical studies in early and advanced prostate cancer models, suggesting that the administration of Yeliva disrupts multiple oncogenic-signaling pathways that are deregulated in prostate cancer.

The clinical studies with RHB-105 (Talicia), RHB-104 , RHB-102 (Bekinda) and Yeliva are registered on www.ClinicalTrials.gov, a web-based service of the U.S. National Institute of Health, which provides access to information on publicly and privately-supported clinical studies. (ClinicalTrials.gov Identifiers: NCT03009396, NCT02757105 and NCT03377179, NCT03198507 respectively).
