At Sesen Bio, we are committed to renewing life for people 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, the VISTA Trial, for the treatment of high-grade non-muscle invasive bladder cancer. Twelve-month data from the trial are anticipated in mid-2019. Vicinium incorporates a tumor-targeting antibody fragment and a protein cytotoxic payload into a single protein molecule designed to selectively and effectively kill cancer cells while sparing healthy cells.
