Under the terms of the expansion, C4T will lead efforts from discovery through defined preclinical or early clinical milestones, depending on the program. Upon C4T reaching these milestone events, Roche will have exclusive options for worldwide rights to continue development and commercialize drugs from these programs. In addition, C4T will have the option to co-develop and co-promote in the U.S. on selected programs. C4T will receive a significant upfront payment and near-term preclinical milestones. Upon success C4T may also receive royalties and potential clinical, regulatory, and commercial milestone payments totaling over $900 million.
