On August 18, 2018, RSG entered into a sublicense agreement (the “Sublicense Agreement”) with Immunovant Sciences GmbH (“ISG”), a wholly-owned subsidiary of the Company, to sublicense this technology, as well as RSG’s know-how and patents necessary for the development, manufacture or commercialization of any compound or product that pertains to immunology.
