We are passionate in our commitment to improving and renewing people's lives. Sesen Bio is a late-stage company developing fusion protein medicines for people with cancer. Our fusion protein approach tethers a tumor-targeting antibody fragment to a protein cytotoxic payload to form a single protein molecule designed to selectively and broadly kill cancer cells while sparing healthy cells and to activate the body's innate immune response system. The most advanced program in our pipeline is Vicinium, a novel investigational anti-cancer treatment that has the potential to treat multiple cancers driven by overexpression of EpCAM, such as non-muscle invasive bladder (NMIBC) and squamous cell carcinoma of the head and neck (SCCHN). We are currently advancing Vicinium in a Phase 3 registration trial for the treatment of people with NMIBC who have been previously treated with bacillus Calmette-Guérin (BCG), with positive three-month efficacy results established and 12-month study results expected in mid-2019. Due to Vicinium's potential to promote an anti-tumor immune response, we believe it holds promise as a combination treatment with immuno-oncology drugs, such as checkpoint inhibitors. The first assessment of this is in a clinical study combing Vicinium with AstraZeneca's durvalumab, in NMIBC. For more information, please visit
