The Swiss pharma will pay Dicerna $200 million, with promises for up to $1.47 billion more in milestone payments tied to development of the RNAi therapeutic, called DCR-HBVS and now in Phase 1 testing.

The collaboration with Roche is Dicerna's fourth with a major drugmaker, following deals with Eli Lilly, Alexion and Boehringer Ingelheim.
