Preliminary positive safety results received from a Phase I study with RHB-104 in 84 healthy adult subjects
-
Additional PK studies with RHB-104 are planned, including long-term population PK and drug-drug interaction studies, to support potential future marketing applications
TEL-AVIV, Israel I January 6, 2014 I RedHill Biopharma Ltd. (RDHL) (RDHL) (the “Company” or “RedHill”), an emerging Israeli biopharmaceutical company focused primarily on the development and acquisition of late clinical-stage, proprietary formulations and combinations of existing drugs, today reported preliminary positive results from a Phase I study with RHB-104, a proprietary combination antibiotic oral capsule formulation for the treatment of Crohn’s disease, currently undergoing a Phase III study in the U.S., with additional clinical sites planned in Canada and Israel (the MAP US study).
The single dose two-way crossover comparative Phase I study included 84 healthy male and female subjects ages 18-45 and was designed to evaluate the effect of co-administration of food on the pharmacokinetics of the constituent components of RHB-104 and two metabolites. The secondary objective of this study was to assess the safety and tolerability of RHB-104 under fed and fasting conditions.
Preliminary pharmacokinetic (of the first 28 subjects) and safety (of all 84 subjects) data have been evaluated. A food effect was demonstrated with the administration of RHB-104, suggesting higher bioavailability with food. There were no serious adverse events reported, and overall safety between fed and fasted subjects was comparable. This preliminary data supports the RHB-104 MAP US Phase III study for Crohn’s disease currently underway in the U.S. and the Phase IIa proof of concept study for multiple sclerosis currently underway in Israel. RHB-104 is administered with food in these two studies.
The preliminary results of the Phase I study, including the pharmacokinetics, bioavailability and safety of RHB-104, are subject to further analysis and final quality control. An independent clinical study report is expected in the coming weeks from the clinical research organization (CRO) which conducted the study.
The Phase I study with RHB-104, conducted in Canada, is the first of several pharmacokinetic (PK) studies which the Company plans to conduct as part of the RHB-104 development program. The additional PK studies are designed to satisfy regulatory requirements for future potential marketing applications, and include a long-term population PK study as part of the RHB-104 MAP US Phase III study for Crohn’s disease, as well as a drug-drug interaction study to be conducted in parallel to the clinical studies currently underway with RHB-104.
Patrick McLean, RHB-104 Product Manager at RedHill Biopharma, said: “The preliminary results from the Phase I study support the safety profile of the RHB-104 proprietary all-in-one combination therapy and provide further insight into the pharmacokinetic properties of this drug. This is the first of several pharmacokinetic studies designed to satisfy regulatory requirements for potential future marketing applications in a number of countries. The additional pharmacokinetic studies will be conducted in parallel to the ongoing RHB-104 clinical trials. Enrollment continues in both the Phase III study in Crohn’s disease and the Phase IIa proof of concept study in multiple sclerosis, and we expect the safety data to contribute to future planned marketing applications for this potentially groundbreaking drug.”
RedHill announced, in November 2013, the dosing of the first patient in the MAP US study – a Phase III clinical study designed to evaluate the safety and efficacy of fixed-dose RHB-104 in patients with moderately to severely active Crohn’s disease. The Company is planning to commence a second Phase III study with RHB-104 for Crohn’s disease in Europe (the MAP Europe study) following successful Scientific Advice Meetings with the UK and Swedish pharmaceutical regulatory agencies. The MAP Europe study is planned to commence in the first half of 2014 and to be conducted in parallel to the ongoing MAP US study. 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.
About RHB-104:
RHB-104 is a proprietary and potentially groundbreaking combination antibiotic therapy in oral capsule formulation, 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 the Mycobacterium avium subspecies paratuberculosis (MAP) infection in susceptible patients. The RHB-104 formulation was originally developed by Professor Thomas Borody, a leading innovator of therapeutic approaches to treating gastrointestinal tract diseases, and who also developed the original triple therapy for peptic ulcer disease associated with H. pylori. Several clinical trials were conducted with earlier formulations of the drug, including two Phase II studies, an Australian Phase III study published by Pfizer and several supplementary studies. The formulation of RHB-104 is covered by several issued and pending patents.
