TEL-AVIV, Israel and RALEIGH, N.C., Oct. 23, 2017 (GLOBE NEWSWIRE) -- 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, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, today announced that it has received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for a new patent
covering RHB-104 for relapsing-remitting multiple sclerosis (MS), which is expected to be valid until 2032, once granted.
RHB-104 is a proprietary, orally-administered, potentially ground-breaking, antibiotic combination therapy with potent intracellular, antimycobacterial and anti-inflammatory properties.
A randomized, double-blind, placebo-controlled first Phase III study with RHB-104 for the treatment of Crohn's disease is currently ongoing (the MAP US study). RedHill expects to complete enrollment in November 2017 and to announce top-line results in the third quarter of 2018.
RedHill plans, subject to regulatory approvals, to initiate a pivotal Phase III study with RHB-104 for the treatment of nontuberculous mycobacteria (NTM) infections in the U.S. in the first half of 2018. RHB-104 was granted Qualified Infectious Disease Product (QIDP) status by the
U.S. FDA for the treatment of NTM infections. QIDP designation allows for Fast-Track development status, Priority Review of a New Drug Application (NDA), if filed, and an additional five years of U.S. market exclusivity on top of the standard exclusivity period or Orphan Designation exclusivity period, as applicable, for a total U.S. market exclusivity of 8-12 years.
RedHill's robust RHB-104 patent portfolio covering its oral antibiotic combination therapy is comprised of more than 60 patents in many countries, including the U.S., Australia, Canada, Japan and multiple European countries
with additional patent claims being pursued.
Results from a Phase IIa, proof-of-concept clinical study, evaluating RHB-104 as an add-on therapy to interferon beta-1a in subjects treated for relapsing-remitting multiple sclerosis (the CEASE MS study), announced in December 2016, demonstrate safety data and clinical signals, supporting additional studies to better investigate the therapeutic potential of RHB-104 in relapsing-remitting multiple sclerosis.
The MAP US Phase III study and the CEASE-MS Phase IIa study 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.
Currently in a first Phase III study for the treatment of Crohn's disease (the MAP US study), RHB-104 is a proprietary, orally-administered, potentially ground-breaking oral antibiotic combination therapy, with potent intracellular, antimycobacterial and anti-inflammatory properties. RHB-104 is based on increasing evidence supporting the hypothesis that Crohn's disease is related to Mycobacterium avium subspecies paratuberculosis (MAP) infection in susceptible patients. The development of RHB-104 is consistent with the growing awareness of the possibility that a bacterially-induced dysregulated immune system may contribute to the pathogenesis of various autoimmune diseases of unknown etiology. Clinical trials
conducted with earlier formulations of RHB-104 include an Australian Phase III study conducted by Pharmacia/Pfizer. RedHill has conducted several supportive studies with the current formulation of RHB-104 and a long-term population pharmacokinetic (pop-PK) study is ongoing as part of the Phase III MAP US study. Additionally, an open-label extension Phase III study (the MAP US2 study) is ongoing to assess the safety and efficacy of RHB-104 in subjects who have completed week 26 assessments in the ongoing Phase III MAP US study and remain with active Crohn's disease (CDAI ≥ 150) at week 26. RHB-104 is covered by several issued and pending patents. RHB-104 was granted Qualified Infectious Disease Product (QIDP) designation by the U.S. FDA for the treatment of
nontuberculous mycobacteria (NTM) infections, providing a Fast-Track development pathway, as well as NDA Priority Review and an additional five years of U.S. market exclusivity, if approved. A pivotal Phase III study with RHB-104 for NTM infections is planned to be initiated. RedHill also completed a Phase IIa, proof-of-concept clinical study, evaluating RHB-104 as an add-on therapy to interferon beta-1a in subjects treated for relapsing-remitting multiple sclerosis (the CEASE MS study), supporting additional studies.
