Orionis Biosciences Inc. is sticking with Genentech Inc. in a second deal to discover small-molecule monovalent glue therapies for treating cancer. Privately held Orionis is getting $105 million up front and could earn more than $2 billion in R&D, development, commercial and net sales milestones, plus royalties. The multiyear collaboration calls for Orionis to handle discovery and optimization of molecular glues, with Genentech in charge of later-stage preclinical and clinical development, regulatory filing and commercialization of any small molecules the partnership produces.
