Centessa Pharmaceuticals plc announced that it has received clearance of its Investigational New Drug (IND) application from the U.S. Food and Drug Administration (FDA) to initiate a Phase 1/2a first-in-human, clinical trial of LB101 for the treatment of solid tumors. LB101, a conditionally tetravalent PD-L1xCD47 LockBody® bispecific monoclonal antibody targeting solid tumors, is the first product candidate developed using the Company's proprietary LockBody technology which is designed to selectively drive potent effector function activity, such as CD47, in the tumor microenvironment (TME) while avoiding systemic toxicity.
