TEL-AVIV, Israel, Oct. 8, 2013 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE: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 positive results from two supplementary pharmacokinetic (PK) studies with RHB-102, an anti-emetic oncology-support drug.
The results of these studies are subject to final QA and an independent study report by the Canadian clinical research organization (CRO) which conducted the studies. The final independent report from the CRO is expected in the coming weeks.
RHB-102 is a patent protected, extended-release (24 hours) oral formulation of ondansetron, the active ingredient in GlaxoSmithKline's Zofran® immediate release tablets for the prevention of radiotherapy induced nausea and vomiting (RINV) and chemotherapy induced nausea and vomiting (CINV).
The Company believes that, if approved for marketing, RHB-102 will be the first and only once-daily oral ondansetron on the U.S. market at the time of approval. With clear potential advantages to cancer patients over the immediate release oral ondansetron tablets currently on the market, including the potential to enhance patient compliance and adherence thanks to increased convenience of use, RHB-102 is targeting a considerable segment of the 5-HT3 anti-emetic market, which was estimated to have worldwide sales of approximately $900 million in 20121.
The supplementary PK program was initiated by the Company in July 2013 to support the planned submission of a New Drug Application (NDA). Following the successful PK program, positive data generated from previous studies with RHB-102 and the Type B meeting held with the U.S. Food and Drug Administration (FDA) in February 2013, the Company is seeking a pre-NDA meeting with the FDA to discuss the clinical aspects of the planned NDA. Subject to the results of the pre-NDA meeting, completion of CMC (Chemistry, Manufacturing and Control) modules, and the required regulatory process, the Company plans to submit an NDA for RHB-102 in the first quarter of 2014, seeking U.S. marketing approval.
The supplementary PK program recently conducted with RHB-102 included two studies. The first study assessed the effect of food on the bioavailability of RHB-102. Results from this study showed that the increase in bioavailability for the extended-release formulation after administration in the fed state is consistent with the pharmacokinetics of Zofran® (ondansetron) immediate release formulation. The second study was a multiple day dosing comparative bioavailability study with Zofran® immediate release tablets as the reference drug. Results from this study demonstrated that the exposure provided by RHB-102 meets the targeted pharmacokinetic parameters and supports once-daily dosage.
Gilead Raday, RedHill Biopharma's Senior VP Corporate and Product Development, commented: "We are very pleased with the results from the two supportive pharmacokinetic studies. We are on schedule with the regulatory plan for RHB-102 and are looking forward to a pre-NDA meeting with the FDA, followed by the planned submission of a New Drug Application for RHB-102 in the first quarter of 2014."
RHB-102 is one of RedHill's most advanced programs, along with RHB-103 oral thin film formulation of rizatriptan, a leading drug for the treatment of acute migraine. The NDA for RHB-103 was submitted in June 2013 and was accepted for substantive review by the FDA with a PDUFA date of February 3, 2014. The Company recently initiated a Phase III study with RHB-104 for the treatment of Crohn's disease and plans to commence a Phase II/III study with RHB-105 (H. pylori) later this month.
