For a whopping $7.1 billion up front, Roche AG is buying Telavant Holdings Inc., a firm that is owned by Roivant Sciences Ltd. and Pfizer Inc. The deal also includes $150 million on the back end, and Roche gains rights to develop, manufacture and commercialize a fully human monoclonal antibody targeting tumor necrosis factor-like ligand 1A, RVT-3101, for treating inflammatory bowel disease (IBD) and possibly other diseases in the U.S. and Japan. Pfizer retains the rights for the rest of the world.
