The planned innovative Phase 2 study of RHB-2041 will be the first ever clinical study in Crohn's Disease (CD) patients who are all MAP-positive, and will correlate mucosal healing with MAP2 infection eradication utilizing novel endpoints and imaging, pending Type C discussions on path to FDA approval, with FDA guidance expected in Q2/25 -- Patent protected until 2041, RHB-204 is a next generation anti-MAP therapy derivative of RHB-1043 which successfully met its groundbreaking Phase 3 study primary and secondary endpoints demonstrating a statistically significant 64% improvement in efficacy versus SoC and showed compelling mucosal healing data in CD patients who underwent colonoscopy. The inclusion of MAP-positive only patients in the planned study with RHB-204 is anticipated to demonstrate a more consistent benefit in the study population across all efficacy outcomes -- Based on insights from RHB-104's statistically significant positive Phase 3 study results, the improved formulation RHB-204 is designed to reduce pill burden and further enhance tolerability, safety and adherence, and along with the uniquely defined patient population (MAP-positive), allows for a study design with a small sample size and decisive endpoints, entailing lower study costs and expedited timeframe -- The role of MAP as a cause of CD, to be tested in this study, supports a paradigm-shifting new therapeutic approach for CD – focused on addressing the actual cause of the disease, not the symptoms -- The multibillion-dollar Crohn's disease market is expected to expand significantly, with sales in the key markets growing from $13.6 billion in 2024 to over $19 billion in 2033, presenting significant commercial potential for a new FDA approved therapy RALEIGH, N.C. and TEL-AVIV, Israel, March 12, 2025 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced plans to advance its groundbreaking late-stage program for Crohn's disease (CD) with initiation of an innovative Phase 2 study of RHB-204 in Mycobacterium avium subspecies paratuberculosis-positive (MAP+) moderate to severe CD, utilizing novel endpoints and the new gold standard in imaging techniques, pending Type C discussions on path to FDA approval with guidance from FDA anticipated next quarter. Patent protected until 2041, and with an expected pediatric orphan designation (subject to FDA approval to transfer from RHB-104), RHB-204, is a novel next generation improved formulation of Phase 3-stage RHB-104, designed to support enhanced tolerability, safety and adherence, with a 40% pill burden reduction, and thus potential better outcomes. In its groundbreaking positive Phase 3 study which met primary and secondary endpoints, RHB-104 demonstrated a 64% increase in efficacy versus SoC, superior remission as early as week 16, improving further at week 26 and continuing through week 52, and also showed compelling mucosal healing data in those patients who underwent colonoscopy. The Phase 2 study is expected to have primary endpoints of mucosal healing (considered a new gold standard in efficacy evaluation in Crohn's disease), MAP status and clinical remission, per FDA guidance following the positive Phase 3 CD study results with RHB-104. The RHB-204 study will be the first ever clinical trial in CD patients who are all MAP-positive, and will correlate mucosal healing with MAP eradication. Based on the successful RHB-104 Phase 3 study insights and specified endpoints, it is expected that the RHB-204 study could be efficiently conducted with a clearly defined and relatively small patient population, precise and decisive endpoints, and an expedited timeframe (with early efficacy indications potentially at just 16 weeks), reducing substantially the anticipated program costs. Clinical study material has already been manufactured and is in place ready for study implementation. The CD market is expected to expand significantly over the 2024–2033 forecast period, with sales in the United States, Japan, and five major European markets, growing from $13.6 billion to $19.1 billion at a compound annual growth rate (CAGR) of 3.87%4. With significant numbers of treatment failures and approximately 1.6 million diagnosed prevalent cases of CD diagnosed globally last year4, there is a strong need for effective new CD therapies. Where applicable, the Company intends to explore the potential for additional regulatory process designations, such as breakthrough therapy designation and fast track designations that may provide additional exclusivity or potential for priority review vouchers, where applicable. Dr. David Y. Graham, Professor of Medicine and Molecular Virology and Microbiology at Baylor College of Medicine, said: "Up to 40% of patients fail to respond to anti-TNF treatment, and over time up to 50% of responders lose response and have disease flare-ups. In addition to the unmet medical need for alternative therapeutic approaches, most of the existing drugs for CD are both expensive and are intravenously administered, further adding to the treatment cost burden. Moreover, several of these existing therapies have known safety issues, including Black Box Warnings, so we believe a safe and effective orally administered therapy would be a very convenient and welcome addition. Based on the safety and efficacy data with concomitant anti-TNFs, immunomodulators and steroids demonstrated in RedHill's initial RHB-104 Phase 3 U.S. study, the development of RHB-204 may provide an expedited route to a safe, oral, stand-alone or combination therapy." "Advances in diagnostic technology have led to increasingly higher identification of MAP in Crohn's diseases patients5," said Gilead Raday, Chief Operating Officer and Head of R&D at RedHill. "Utilizing gold standard imaging technology to provide clear and unambiguous efficacy results, the study is designed to include only MAP positive CD patients and is expected to increase the study's power, potentially allowing to demonstrate the benefits of RHB-204 anti-MAP therapy in a relatively small sample size, over and above the promising efficacy observed in the positive Phase 3 study results of RHB-104's in all-comer CD patients. RedHill is actively pursuing partnering and collaborations for this program, including ongoing discussions with non-dilutive external funding sources, which may pave the way to a much-needed new therapeutic modality for CD, focused on addressing a suspected cause of the disease, as opposed to just its symptoms." The randomized, double-blind, placebo-controlled 331-patient Phase 3 study of RHB-104 in active Crohn's disease met its primary and secondary endpoints, showing RHB-104 standard of care (SoC) to be 64% more effective than SoC alone, was published in the peer-reviewed journal, Antibiotics6. In the global study, conducted across 92 sites, 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). In the secondary endpoint of mucosal healing, endoscopy was performed in a group of 35 patients who volunteered to undergo colonoscopy, with results showing meaningful improvement in endoscopic healing (Simple Endoscopic Score for Crohn's Disease (SES-CD)) at week 26 (statistically significant at 25% decrease with similar trend at 50% decrease), despite the small sample size. Further corroborating these results was the statistically significantly marked and continuous decline of inflammatory marker, fecal calprotectin (FCP) - an accepted surrogate for mucosal healing - in the RHB-104 active arm from baseline through week 52 in patients with high calprotectin at baseline. 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. About Crohn's Disease: Crohn's disease (CD) is a form of Inflammatory Bowel Disease (IBD) causing inflammation of digestive tract tissue that can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition. CD 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. According to the Cleveland Clinic, experts estimate that more than three-quarters of a million Americans and approximately 6-8 million people globally have Crohn's disease Commonly used FDA approved therapies in the treatment of CD include: Abbvie's Humira® (adalimumab), Janssen's Remicade® (infliximab) and Stelara® (Ustekinumab), BMS's Zeposia® (ozanimod) and Pfizer's Xeljanz® (tofacitinib). About RHB-204 RHB-204 is a proprietary, fixed-dose oral capsule containing a combination of clarithromycin, rifabutin and clofazimine, at specific doses designed to safely and effectively treat MAP+-related Crohn's disease. Patent protected until at least 2041, and with an expected pediatric orphan designation (subject to FDA approval to transfer from RHB-104), RHB-204 is a next-generation formulation of RHB-104 with an optimized formulation for the treatment of CD. It contains the same three antimicrobial agents with potent intracellular, anti-mycobacterial and anti-inflammatory properties, and with an optimized dosing profile, RHB-204 provides the potential for enhanced tolerability, safety and compliance with a 40% pill burden reduction. RHB-204 is supported by a strong foundation of clinical data from the positive safety and efficacy results achieved in the Phase 3 study of RHB-104 in CD, with its potential further demonstrated using mucosal healing imaging, considered to be the gold standard for efficacy evaluation in CD. Originally developed for the treatment of pulmonary NTM disease caused by MAC, RHB-204 was granted FDA Fast Track and Orphan Drug Designation, in addition to QIDP Designation under the Generating Antibiotic Incentives Now Act (GAIN Act), extending U.S. post-approval U.S. market exclusivity to a potential total of 12 years. RHB-204 has additionally been granted EU Orphan Designation, providing eligibility for 10 years EU post-approval market exclusivity. RedHill has protection for RHB-204, and its use in treating pulmonary MAC disease, until 2041. About RedHill Biopharma RedHill Biopharma Ltd.
