Regeneron, Alnylam to take on NASH in discovery deal Regeneron and RNA biotech Alnylam are teaming up to identify RNAi treatments for the chronic liver disease, nonalcoholic steatohepatitis (NASH), and potentially for other diseases too. The collaboration will build on new findings from Regeneron identifying a link between a variant of the HSD17B13 gene and a lower risk of chronic liver disease. Alnylam will bring its gene-silencing RNAi technology to the table, while Regeneron will contribute research on the target.(FierceBiotech)
