Newly published in the peer-reviewed journal Antibiotics, the 331-patient Phase 3 Crohn's disease study data shows the primary endpoint of clinical remission at week 26 was achieved, with high statistical significance, in 36.7% (61/166) of orally administered RHB-104 plus standard of care (SoC) patients, compared to 22.4% (37/165) of placebo plus SoC patients (p=0.0048); Safety profile similar to placebo. Study conducted across more than 100 sites The advanced stage clinical data demonstrating the potential efficacy of oral RHB-104 triple antimicrobial therapy targeting Mycobacterium avium subspecies paratuberculosis (MAP,) supports the paradigm-changing hypothesis of a Mycobacterial basis to Crohn's disease, where high unmet medical need exists "This ground-breaking data shows that RHB-104, which contains antimicrobial therapy directed against Mycobacterium paratuberculosis, or MAP, which typically infects cattle, appears to be effective for the treatment of Crohn's disease - potentially opening a new avenue of therapy directed against its possible cause," said Dr. David Y. Graham, Professor of Medicine and Molecular Virology and Microbiology at Baylor College of Medicine, the lead investigator of the study. Dr. Graham added: "It is particularly important to note that RHB-104 proved beneficial to patients receiving anti-TNF agents, corticosteroids or immunosuppressive agents, and may also have a role as an add-on therapy for patients not responding to their current treatment." The Crohn's disease market was valued at more than $13 billion in 2023. Commonly used therapies in the treatment of Crohn's include: Abbvie's Humira® (adalimumab), Janssen's Remicade® (infliximab) and Stelara® (ustekinumab), BMS's Zeposia® (ozanimod) and Pfizer's Xeljanz® (tofacitinib) TEL AVIV, Israel and RALEIGH, N.C., Aug. 1, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the new publication of ground-breaking positive data showing that triple antimicrobial therapy with RHB-104[1] plus standard of care (SoC), targeting Mycobacterium avium subspecies paratuberculosis (MAP), is 64% more effective than SoC alone in Crohn's disease, supporting the hypothesis of a Mycobacterial basis to the disease. The data from the randomized, double-blind, placebo-controlled 331-patient Phase 3 study of anti-mycobacterial therapy (RHB-104) in active Crohn's disease, was published in the peer-reviewed journal, Antibiotics[2]. In the global study, conducted across more than 100 sites across the U.S. Europe and other locations, a total of 166 patients were randomized to receive RHB-104 plus SoC and 165 to placebo plus SoC. Data for the primary endpoint, clinical remission at week 26, shows, with high statistical significance, that 36.7% (61/166) of RHB-104 patients achieved clinical remission at week 26 vs. 22.4% (37/165) of placebo patients (p = 0.0048). RHB-104 was found to be generally safe and well tolerated, with adverse event reporting similar to placebo. Full results are available in the publication. "This study was designed based on the hypothesis that infection with MAP is the primary cause of Crohn's disease and that antimicrobial therapy designed to treat MAP would favorably influence the outcome of Crohn's disease," said study lead investigator, Dr. David Y. Graham, Professor of Medicine and Molecular Virology and Microbiology at Baylor College of Medicine and the Michael E. DeBakey Veterans Administration Hospital in Houston, Texas, USA. "We believe that this data shows that treatment with RedHill's RHB-104 appears to be effective for the treatment of Crohn's disease – this is important as an effective and safe oral therapy for Crohn's could be highly beneficial to the patients and treating community. A unique feature of this Phase 3 study was that patients were permitted concomitant treatment with infliximab, adalimumab and/or corticosteroids at study entry. To our knowledge, no other similar Crohn's trial has allowed tumor necrosis factor (TNF) agents to be continued throughout the treatment period. It is therefore also important to note that RedHill's RHB-104 proved beneficial to patients receiving corticosteroids, immunosuppressive agents, or anti-TNF agents and may also have a role as an add-on therapy for patients not responding to their current treatment." "Crohn's disease causes immense suffering to millions of patients globally and sometimes leads to death due to various complications. Recognizing this, RedHill is firmly committed to the RHB-104 potential paradigm-changing Phase 3-stage program. It has been more than 100 years since Scottish surgeon, Dalziel, first sowed the seeds of a possible link between MAP and Crohn's. Evidence has grown of MAP involvement in the etiology of Crohn's, being associated with immune signaling dysregulation and being identified in over 50% of Crohn's patients," said Dror Ben-Asher, RedHill's Chief Executive Officer. "This makes the new peer-reviewed publication of these data highly exciting as Crohn's is a terrible disease that remains steadfastly resistant to the search for a cure – despite the enormous research efforts made in the field of immunosuppression. We have a long-held conviction in the MAP approach – vindicated by this compelling data. Planning ahead, the advent of an accurate and reliable MAP diagnostic, allied to this proven triple antimicrobial therapeutic strategy, has the potential to change the treatment paradigm in inflammatory bowel disease (IBD). Accordingly, we have been pursuing creative partnership models to advance the development of RHB-104 and intend to update the market in due course." About Crohn's Disease: Effecting an estimated one million Americans, Crohn's disease can be highly debilitating and remains a serious burden for both patients and healthcare systems; destroying quality of life and even leading to life-threatening complications. There is no known cure for Crohn's disease. It is a form of IBD causing inflammation of digestive tract tissue that can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition. Different areas of the digestive tract can be affected by the inflammation caused by Crohn's disease, but it is often associated with the small intestine. However, this inflammation can often spread further and deeper into the bowel. The Crohn's disease market was valued at more than $13 billion in 2023.[3] Commonly used therapies in the treatment of Crohn's include: Abbvie's Humira® (adalimumab), Janssen's Remicade® (infliximab) and Stelara® (Ustekinumab), BMS's Zeposia® (ozanimod) and Pfizer's Xeljanz® (tofacitinib). About RHB-104: RHB-104 is a proprietary, orally administered antibiotic combination therapy, with intracellular, antimycobacterial and anti-inflammatory properties. The randomized, double-blind, placebo-controlled, first Phase 3 study with RHB-104 in Crohn's disease (the MAP US study) successfully met both its primary endpoint and key secondary endpoints and presented the benefit of RHB-104 as an add-on therapy to standard-of-care treatments for Crohn's disease, including anti-TNF agents. The company also reported supportive top-line results from an open-label extension Phase 3 study (MAP US2) evaluating the safety and efficacy of RHB-104 in subjects with persistent active Crohn's disease after 26 weeks of blinded study therapy in MAP US. RHB-104 was developed 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.
