We presented new pre-clinical data supporting the selection of the ALN-AS1 Development Candidate for the treatment of hepatic porphyrias, including acute intermittent porphyria (AIP). The new research, presented at the 9th
Annual Meeting of the Oligonucleotide Therapeutics Society, held October 6 – 8, 2013 in Naples, Italy, showed that multi-dose administration of a GalNAc-siRNA targeting ALAS-1 led to rapid, dose-dependent, and long-lasting knockdown of the ALAS-1 mRNA in non-human primates, with an ED50
of approximately 1.25 mg/kg. Further, in a rat model of AIP, ALN-AS1 administration at doses as low as 2.5 mg/kg resulted in a complete blunting of phenobarbital-induced over-production of PBG and ALA, the toxic heme intermediates in AIP.
