RHB-104 is a proprietary, orally-administered, potentially groundbreaking antibiotic combination therapy with potent intracellular, antimycobacterial and anti-inflammatory properties.
The MAP US study is a randomized, double-blind, placebo-controlled first Phase III study, intended to evaluate the safety and efficacy of RHB-104 in patients with moderately to severely-active Crohn's disease (defined as Crohn's Disease Activity Index (CDAI) between 220 and 450). To date, 266 patients out of a planned total of 410 patients have been enrolled in the study, which is being conducted in up to 150 clinical sites in the
The open-label extension study (the MAP US2 study) is intended to assess the safety and efficacy of RHB-104 in patients who have completed 26 weeks of treatment in the ongoing MAP US Phase III study and remain with active Crohn's disease (CDAI > 150) at week 26, the MAP US study's primary endpoint. These patients have the opportunity to receive treatment with RHB-104 for a 52-week period in the open-label extension study. This study is considered separate from the ongoing MAP US Phase III study, and data collected will
be supplemental to the MAP US study data. The open-label extension study's primary endpoint is disease remission at week 16, defined as CDAI less than 150. The open-label extension MAP US2 study is planned to enroll approximately 100 subjects in up to 150 clinical sites in the
A second independent Data and Safety Monitoring Board (DSMB) meeting of the MAP US
Phase III study, expected in mid-2017, will include an interim efficacy analysis and will evaluate the option for an early stop for success for overwhelming efficacy, according to a pre-specified statistical significance threshold. Assuming the study is not stopped for success or inefficacy following the DSMB meeting in mid-2017, completion of recruitment for the MAP US study is expected by the end of 2017. In
The development of RHB-104 is based on increasing evidence supporting the hypothesis that Crohn's disease, and potentially other autoimmune diseases, are 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.
The MAP US Phase III study is registered on www.ClinicalTrials.gov, a web-based service of the
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 groundbreaking 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 caused by 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 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 study (the MAP US2 study) is ongoing to assess the safety and efficacy of RHB-104 in patients who have completed 26 weeks of treatment 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. RedHill has also completed 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 (the CEASE MS study). Top-line final results from the CEASE MS study suggest meaningful positive safety and clinical signals upon 24 weeks of treatment with RHB-104 as an add-on therapy, thereby supporting further clinical development.
