RedHill Biopharma Announces Acceptance of Phase III Trial Application in Europe with RHB-104 for Crohn's Disease

TEL-AVIV, Israel, June 16, 2015 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) ("RedHill" or the "Company"), an Israeli biopharmaceutical company focused on late clinical-stage, proprietary, orally-administered, small molecule drugs for inflammatory and gastrointestinal diseases, including gastrointestinal cancers, today announced that the UK Medicines and Healthcare Products Regulatory Agency (MHRA) has accepted RedHill's Clinical Trial Application (CTA) to initiate a second Phase III study of RHB-104 for Crohn's disease (the MAP EU study). The MAP EU study is planned to commence in a selected number of European counties, and, once initiated, will run in parallel with the currently ongoing MAP US first Phase III study. RHB-104 is a proprietary and potentially groundbreaking antibiotic combination therapy in oral capsule formulation, with potent intracellular, anti-mycobacterial and anti-inflammatory properties.

The randomized, double-blind, placebo-controlled MAP EU Phase III study is expected to enroll 360 patients with moderately active Crohn's disease. Patients will be randomized 2:1 to receive either RHB-104 or a placebo for 52 weeks, and then evaluated for remission at week 26 as the primary endpoint.

In addition, RHB-104 is currently undergoing a first Phase III study in the U.S., Canada, Israel, Australia, New Zealand and Europe (the MAP US study). The ongoing randomized, double-blind, placebo-controlled MAP US Phase III study is expected to enroll 270 patients with moderately to severely active Crohn's disease. Patients are randomized 1:1 to receive either RHB-104 or a placebo for 52 weeks, and are then evaluated for the primary endpoint of remission at week 26 of treatment. Interim analysis of the MAP US study is expected in the second half of 2016, after half of the patients expected to be enrolled in the study will have completed 26 weeks of treatment.

Aida Bibliowicz, RedHill's VP, Clinical Affairs Europe, said: "We are very pleased that the CTA for the Phase III MAP EU study has been accepted by the UK MHRA. This is an important milestone for the development of RHB-104 for Crohn's disease and represents a significant achievement in our ongoing preparations for the initiation of the second Phase III study for this drug candidate, to be conducted in Europe. The first Phase III MAP US study of RHB-104 for Crohn's disease is currently ongoing in the U.S. and other countries, with approximately 80 of the planned 120 clinical sites already initiated."

The MAP US Phase III study is registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies: https://www.clinicaltrials.gov/ct2/show/NCT01951326.

About RHB-104:

Currently in a first Phase III study for the treatment of Crohn's disease (the MAP US study) and a second Phase III study is being prepared (the MAP EU study), RHB-104 is a proprietary and potentially groundbreaking antibiotic combination therapy in oral capsule formulation, with potent intracellular, anti-mycobacterial and anti-inflammatory properties. RHB-104 is based on increasing evidence supporting the hypothesis that Crohn's disease is caused by the Mycobacterium avium subspecies paratuberculosis (MAP) infection in susceptible patients. Clinical trials conducted with earlier formulations of RHB-104 include an Australian Phase III study conducted by 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. RHB-104 is covered by several issued and pending patents. RedHill is also conducting a Phase IIa, proof-of-concept clinical study, evaluating RHB-104 as an add-on therapy to interferon beta-1a in patients treated for relapsing-remitting multiple sclerosis (RRMS).
