At Sesen Bio, we are committed to saving and improving the lives of patients with cancer. We are a late-stage clinical company advancing fusion protein therapies based on our Targeted Protein Therapeutics platform. Our lead program, Vicinium®, also known as VB4-845, is currently in a Phase 3 registration trial for the treatment of high-risk, BCG-unresponsive non-muscle invasive bladder cancer (NMIBC). In December 2019, the Company initiated the BLA submission for Vicinium to the FDA under rolling review. Vicinium is a locally administered targeted fusion protein composed of an anti-EPCAM antibody fragment tethered to a truncated form of Pseudomonas Exotoxin A for the treatment of high-risk NMIBC.
