RedHill Biopharma’s Potential Crohn’s Treatment, RHB-104, Likely to Receive US Patent

RedHill Biopharma’s Potential Crohn’s Treatment, RHB-104, Likely to Receive US Patent

RedHill Biopharma recently announced that it received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for its patent covering RHB-104, a new oral combination drug currently being assessed in clinical trials for Crohn's disease treatment.

RedHill is an Israeli biopharmaceutical company focusing on the development of orally administered drugs for inflammatory and gastrointestinal diseases, such as Crohn's. RHB-104, is composed of three antibiotics, rifabutin, clarithromycin, and clofazamine. According to RedHill, the drug has potent intracellular, anti-mycobacterial and anti-inflammatory properties, and is currently in a Phase 3 trial as a Crohn’s treatment. The drug builds on evidence that infection with the bacterial subspecies Mycobacterium avium paratuberculosis (MAP) causes Crohn's disease in susceptible patients.

MAP most commonly infects dairy cows and non-human primates, but appears to have also spread to humans. None of the antibiotics included in the preparation are new, and as separate drugs, they have been on the market for a couple of decades. The patent, however, applies to the combination preparation, as an oral capsule, and its use. If granted, the patent is expected to be valid until 2029.

The MAP U.S. study is a Phase 3 clinical trial investigating RHB-104 for Crohn’s disease in the U.S., Canada, Australia and several other countries. A second Phase 3 trial — the MAP EU study — is in the planning stage and will be conducted in a number of European countrie

    I have been following since quite sometime the progress of the RHb 104 for Crohn’s disease as i am quite optimistic about Map hypothesis and hope it materialize. What is not clear is when the medication will be in the market? If ever.. It gives me hope of a cure ..

    I am very optimistic about this drug because I’ve been following the research on MAP and just know there’s validity to this theory. I just want this disease cured or managed safely giving our kids a chance at life. How do we find out about a release date?
