Pointing to his company’s work on “the next frontier in small molecules,” Ribometrix Inc. CEO Mike Solomon said the potential $1 billion-plus deal with Roche Holding AG offers evidence of big pharma’s mounting interest. Expertise in RNA folds helped Ribometrix nail down an agreement with Basel, Switzerland-based Roche’s Genentech arm that brings $25 million up front and potential milestone payments beyond $1 billion, as the pair discovers and develops RNA-targeted small-molecule therapeutics. Genentech gains exclusive rights to several predefined targets, including an exclusive global license for the development and commercialization of molecules.
