RedHill Migraine Trial Successful
RedHill Biopharma Ltd. (TASE: RDHL) announced positive results in a pivotal bioequivalence clinical trial with RHB-103, an oral thin-film formulation of Rizatriptan for the treatment of acute migraine. RedHill has exclusive world-wide rights and is developing RHB-103 with its Canadian co-development partner IntelGenx, Corp. (TSX: IGX ; OTCBB: IGXT).
Analysis of the results demonstrates that the trial met its specified endpoints and FDA’s criteria, in all parameters for bioequivalence, between RedHill’s RHB-103 oral thin-film, and Merck & Co.’s Maxalt-MLT, a leading, approved, migraine treatment, based on Rizatriptan, a 5-HT1 receptor agonist drug.
RedHill awaits the final report of the clinical trial results, subject to which the Company and
IntelGenx intend to file with the FDA a New Drug Application for a US marketing approval
(NDA).
The trial was conducted in Canada following discussions with the FDA and under a CTA
(Clinical Trial Application) approval from Health Canada.
RHB-103 is based on IntelGenx’ proprietary immediate release VersaFilm oral thin-film
technology for rapid dissolution, and is targeting a significant segment of the migraine market
– namely the family of triptan migraine drugs – estimated at approximately $2 billion in 2011.
The world-wide sales of Merck & Co.’s Rizatriptan drugs, under their various names,
including Maxalt and Maxalt-MLT – the reference drug in the RHB-103 pivotal clinical trial
– exceeded $600 million in 2011.
