TEL-AVIV, Israel and RALEIGH, NC, USA I July 30, 2018 I 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 (GI) diseases, today announced positive top-line safety and efficacy results from the first Phase III study with RHB-104 for Crohn’s disease (the MAP US study). The study successfully met its primary endpoint and key secondary endpoints.
Top-line results in the intent-to-treat (ITT) population demonstrated superiority of RHB-104 over placebo in achieving remission at week 26, defined as Crohn’s Disease Active Index (CDAI) value of less than 150, the primary endpoint of the study. The proportion of patients meeting the primary endpoint was significantly greater in the RHB-104 group compared to placebo (37% vs. 23%, p= 0.013).
Ira Kalfus, M.D., RedHill’s medical director, said: “The robust results of this study demonstrate that RHB-104 could become a leading therapeutic option in Crohn’s disease and bring hope to patients worldwide.”
The study also successfully met key secondary endpoints, demonstrating consistent benefit to Crohn’s disease patients treated with RHB-104.
Patients treated with RHB-104 also achieved a statistically significant greater response at week 26 (defined as a decrease of ≥100 in CDAI from baseline) compared to placebo (44% vs. 31%, p= 0.028).
Patients treated with RHB-104 also experienced a statistically significant benefit in achieving early remission defined as remission at week 16 (42% vs. 29%, p= 0.019).
Patients receiving RHB-104 also experienced a statistically significant benefit in durable remission over weeks 16-52, defined as continuous remission throughout the period, (18% vs. 9%, p= 0.038), demonstrating an improvement of 100% over placebo1.
At 52 weeks of treatment, remission in the RHB-104 arm continued to be favorable to placebo (27% vs. 20%, p= 0.155).
An analysis of maintenance of remission at week 52 in subjects noted to be in remission at week 16 also demonstrated statistically significant benefit with RHB-104 over placebo (25% vs. 12%, p= 0.007).
RHB-104 was found to be generally safe and well tolerated. Top-line results demonstrated that the active and placebo treatment groups experienced similarly low rates of serious adverse events and treatment emergent adverse events leading to study drug discontinuation, indicating a positive safety profile for RHB-104.
The company will continue to assess additional exploratory endpoints as data becomes available, including mucosal healing, MAP status, quality of life assessment, sub-population analyses and pharmacokinetics. Additional data is expected in the comings months.
Dr. Kalfus added: “This is the first global, double-blind, placebo-controlled study that demonstrates the efficacy of anti-MAP therapy in Crohn’s disease. The availability of antibiotic therapy for treating Crohn’s disease could be transformative. The results from the MAP US study are excellent, successfully meeting the primary endpoint at week 26 and demonstrating that treatment with RHB-104 also has an early benefit at week 16, which is persistent though week 52. The study results compare favorably to existing standard-of-care therapies2. RHB-104 appeared to be safe and well tolerated in the study. We continue to analyze the study data and plan to meet with key opinion leaders and the FDA to present the data package and discuss the development path to potential approval of RHB-104.”
Professor David Graham, M.D., M.A.C.G., lead investigator of the RHB-104 MAP US Phase III study, added: “I am impressed and extremely pleased with the results of the study, which indicate that RHB-104 could lead to a paradigm shift in the treatment of Crohn’s disease, a chronic and debilitating and currently incurable condition with a strong unmet medical need. Many patients with Crohn’s disease do not achieve remission on current standard-of-care therapies, which are accompanied with poor side effects. RHB-104 appears to have the potential to become a promising, new, orally-administered therapy for this important debilitating disease.”
Dror Ben-Asher, RedHill’s CEO, said: “The compelling top-line results with RHB-104, our potential ground-breaking therapy, are a remarkable accomplishment. We thank the patients who participated in this global study, as well as the physicians and clinical staff who supported them. We also want to extend our deep gratitude to the lead investigator of the study, Professor David Graham, to the RedHill team and to the experts and vendors for their commitment throughout the study. We look forward to discussing the path to approval with the FDA and to accelerating discussions with potential pharma partners.”
The MAP US randomized, double-blind, placebo-controlled first Phase III study of RHB-104 enrolled 331 subjects with moderately to severely active Crohn’s disease (defined as CDAI between 220 and 450) in the U.S., Canada, Europe, Australia, New Zealand and Israel. Subjects were randomized 1:1 to receive RHB-104 or placebo, on-top of baseline background medication including of 5-ASAs, corticosteroids, immunomodulators or anti-TNFα agents.
In addition, an open-label extension Phase III study (MAP US2 study) is ongoing to evaluate the safety and efficacy of RHB-104 in subjects who remain with active Crohn’s disease (CDAI ≥ 150) after 26 weeks of blinded study therapy in the Phase III MAP US study.
Additional clinical studies are most likely to be required to support a U.S. New Drug Application (NDA) for RHB-104, if filed. RedHill will meet with key opinion leaders and the U.S. Food and Drug Administration (FDA) to present the data package and discuss the development path to potential approval and will continue discussions with potential partners for RHB-104.
As of 2017, approximately 1.5 million people worldwide had been diagnosed with Crohn’s disease. Global sales of Crohn’s disease therapies are estimated to exceed $10 billion in 20183.
The top-line results were provided to RedHill by an independent third party following an independent analysis and remain subject to completion of the independent review and analysis of the underlying data, including all safety, secondary and other outcome measures, and completion of the Clinical Study Report (CSR). Detailed results from the Phase III study will be submitted for presentation at upcoming scientific conferences.
RedHill will host a conference call today, Monday, July 30, 2018, at 8:30 a.m. ET, to discuss the MAP US study results.
The webcast, including a slide presentation, will be broadcasted live and available for replay on the Company’s website, http://ir.redhillbio.com/events, for 30 days.

About RHB-104:
RHB-104 is a potentially ground-breaking, proprietary, orally-administered antibiotic combination therapy, with potent intracellular, antimycobacterial and anti-inflammatory properties, with positive top-line results in a first Phase III study. RHB-104 is based on the hypothesis that Crohn’s disease is caused by 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. Positive top-line results from the first Phase III study with RHB-104 in Crohn’s disease (the MAP US study) were announced in July 2018. The study successfully met its primary endpoint and key secondary endpoints. RedHill has conducted several supportive studies with the current formulation of RHB-104 and a population pharmacokinetic (pop-PK) study is ongoing as part of the Phase III MAP US study. Additionally, an open-label extension Phase III study (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). Additional clinical studies are likely to be required to support a U.S. NDA for RHB-104, if filed. RHB-104 is covered by several issued and pending patents. 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 (CEASE MS study), supporting additional studies.
