TEL-AVIV, Israel and RALEIGH, N.C., Aug. 20, 2018 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on proprietary drugs for gastrointestinal diseases, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for a new formulation patent covering RHB-106, which is expected to be valid until at least 2033. Additional patent applications for RHB-106 are pending in numerous other countries.
RHB-106 is an encapsulated bowel cleanser licensed to Salix Pharmaceuticals (“Salix”), a wholly-owned subsidiary of Bausch Health Companies Inc. (NYSE: BHC and TSX: BHC).
RedHill recently amended its 2014 worldwide license agreement with Salix relating to RHB-106, as well as additional related rights. The amendment clarified Salix’s future development efforts and provides for enhanced involvement by RedHill in certain intellectual property matters and increased the lower end of the range of royalty payments to be paid to RedHill on net sales from low single digits to high single digits. Milestone payments remain unchanged. RedHill continues to assist Salix in the development of RHB-106, as needed.
RHB-106 is an encapsulated formulation intended for the preparation and cleansing of the gastrointestinal tract prior to abdominal procedures and diagnostic tests, such as colonoscopies, barium enemas or virtual colonoscopies, as well as surgical interventions, such as laparotomies. RHB-106 is a tasteless solid oral dosage, potentially allowing for an unobstructed procedure with reduced side effects and improved patient compliance.
