Regeneron Pharmaceuticals and Alnylam Pharmaceuticals have entered a collaboration to identify RNAi therapeutics for the chronic liver disease nonalcoholic steatohepatitis (NASH) and potentially other related diseases. 

The discovery collaboration is based on a new Regeneron publication in the New England Journal of Medicine identifying for the first time a variant in the HSD17B13 gene that is associated with reduced risk of chronic liver diseases. RNA interference (RNAi) therapeutics represent a novel and innovative approach to specifically target and silence any gene involved in the cause or pathway of human disease; this approach could potentially mimic the naturally occurring loss-of-function genetic variation in HSD17B13 seen in people who are protected from NASH disease progression. 

“At Alnylam, we are dedicated to advancing RNAi therapeutics as a new class of medicines for patients with few or no treatment alternatives,” said John Maraganore, Ph.D., chief executive officer at Alnylam. “As we transition Alnylam toward commercialization in rare diseases, the prospect of collaborating with a scientific leader like Regeneron on innovative medicines for more prevalent diseases like NASH makes perfect strategic sense. We believe the exquisite specificity afforded by the RNAi mechanism of action and our industry-leading, proprietary GalNAc-conjugate approach for delivery to the liver is an unparalleled combination for developing an RNAi therapeutic toward genetically-validated targets in NASH.”

Under the discovery collaboration, Regeneron will contribute research on the hepatocyte-expressed, genetically-validated HSD17B13 target, and Alnylam will leverage its RNAi therapeutics platform to identify compounds directed to this target. Regeneron and Alnylam intend to enter into a separate, fifty-fifty collaboration to further research, co-develop and commercialize any therapeutic product candidates that emerge from these discovery efforts.

This is Regeneron and Alnylam’s second recent collaboration founded on genetic exploration. In January 2018, Alnylam, alongside multiple other leading life sciences companies, joined Regeneron’s pre-competitive consortium to sequence 500,000 individuals in the UK Biobank health resource and subsequently make the data publicly available to the global research community.
