RedHill Announces Poster Presentation on New Potential Therapeutic Applications of RHB-107 at the AACR 2018 Annual Meeting
19 March, 2018
Data from non-clinical studies indicated that WX-UK1, the active metabolite of RHB-107 (formerly MESUPRON), is a potent and specific inhibitor of five human serine proteases, suggesting new potential therapeutic applications in oncology and inflammatory digestive diseases
TEL-AVIV, Israel / RALEIGH, NC, March 19, 2018 RedHill Biopharma Ltd. (NASDAQ: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on late clinical-stage development and commercialization of proprietary drugs for gastrointestinal diseases and cancer, today announced the presentation of a poster at the American Association for Cancer Research (AACR) 2018 Annual Meeting. The abstract (number 4200) will be presented by Mark L. Levitt, MD, Ph.D., Medical Director, Oncology at RedHill, on Tuesday, April 17, 2018 from 1:00 PM to 5:00 PM CDT, at McCormick Place, Chicago, IL.
The abstract1 presentation, entitled ‘New potential therapeutic applications of WX-UK1, as a specific and potent inhibitor of human trypsin-like proteases’, describes data from non-clinical studies concluding that WX-UK1, the active metabolite of RHB-107 (formerly MESUPRON) (INN: upamostat), is a potent and specific inhibitor of five human serine proteases (trypsin-3, trypsin-2, trypsin-1, matriptase-1 and trypsin-6). Several of these serine proteases are associated with cancer progression and metastasis. The non-clinical studies suggest new potential therapeutic applications of WX-UK1 in oncology and inflammatory gastrointestinal diseases. The abstract was authored by scientists from the Department of Molecular Biology and Genetics of Aarhus University in collaboration with RedHill2.
RHB-107 is a proprietary, first-in-class, orally-administered potent serine protease inhibitor, presenting a new non-cytotoxic approach to cancer therapy, as well as other indications of high unmet need, such as inflammatory digestive diseases and inflammatory lung diseases. RHB-107 has undergone several Phase I studies and two Phase II proof-of-concept studies in cancer patients.
With the recent identification of several serine proteases as high-affinity molecular targets, RedHill is evaluating utilization of RHB-107 in both cancer and inflammatory digestive diseases.
About RHB-107 (upamostat):
RHB-107 (formerly MESUPRON) (INN: upamostat) is a proprietary, first-in-class, orally-administered potent inhibitor of several serine proteases targeting cancer and inflammatory gastrointestinal diseases. Protease inhibitors have been shown to play key roles in tumor invasion and the metastasis process. High levels of certain proteases are associated with poor prognosis in various solid tumor cancers, such as pancreatic, gastric, breast and prostate cancers. RHB-107 was previously granted FDA Orphan Drug designation for the treatment of pancreatic cancer. RHB-107 presents a new non-cytotoxic approach to cancer therapy with several potential mechanisms of action to inhibit tumor invasion and metastasis. RHB-107 has undergone several Phase I studies and two Phase II proof-of-concept studies. The first Phase II study was in locally-advanced, non-metastatic pancreatic cancer and the second study in metastatic breast cancer in combination with first-line chemotherapeutic agents. RedHill was granted a new patent from the United States Patent and Trademark Office (USPTO) directed to a combination of RHB-107, YELIVA®, RedHill’s two Phase II-stage investigational compounds, and a known antibiotic. RedHill acquired the exclusive worldwide rights to RHB-107, excluding China, Hong Kong, Taiwan and Macao, from Germany’s Heidelberg Pharmaceuticals (formerly WILEX AG) for all indications.
