  • The new patent expands the robust patent portfolio covering RHB-104 and RHB-204
     
  • RedHill plans to initiate a pivotal Phase 3 study with RHB-204 for the treatment of pulmonary nontuberculous mycobacteria (NTM) infections in the second half of 2019
     
  • RedHill plans to meet with the FDA in the second half of 2019 to discuss the design of a confirmatory Phase 3 with RHB-104 for Crohn’s disease

TEL-AVIV, Israel and RALEIGH, N.C., June 10, 2019 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on gastrointestinal diseases, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for a new patent covering RHB-104 for Crohn’s disease and RHB-204 for Mycobacterium avium complex (MAC) disease, the most common cause of pulmonary nontuberculous mycobacteria (NTM) infections1. Once granted, the patent is expected to be valid until at least 2029.

Danielle Abramson, Ph.D., RedHill’s Vice President of Intellectual Property and Research, stated: “We continue to build and strengthen our intellectual property portfolio covering both RHB-104 and RHB-204. Once this new patent is granted, the robust patent portfolio for RHB-104 will include seven issued U.S. patents, three of which also protect RHB-204, as well as additional issued and pending patents worldwide. We continue to work diligently to expand the existing patent portfolio covering our advanced clinical programs including Talicia for H. pylori infection for which a new drug application (NDA) has been submitted earlier this quarter with priority review eligibility.”

RedHill plans to initiate a pivotal Phase 3 study with RHB-204 for the treatment of pulmonary NTM infections in the second half of 2019, subject to completion of the ongoing supportive non-clinical program and additional input from the U.S. Food and Drug Administration (FDA). The study is intended to assess the efficacy and safety of RHB-204 and potentially support its approval as a stand-alone, first-line treatment for pulmonary NTM infections caused by MAC.

RedHill plans to meet with the FDA in the second half of 2019 to discuss the development path toward potential approval of RHB-104, including the design of a confirmatory Phase 3 study. The MAP US randomized, double-blind, placebo-controlled first Phase 3 study with RHB-104 for Crohn’s disease successfully met both its primary endpoint and its key secondary endpoints and presented the broad benefit of RHB-104 as an add-on therapy to standard-of-care treatments for Crohn’s disease, including anti-TNFs.
