About TScan:

TScan Therapeutics was founded in 2018 by a small group of scientists led by Dr. Stephen Elledge (Harvard Medical School/HHMI). TScan is discovering and developing novel TCR-engineered T cell therapies for the treatment of cancer. TScan’s discovery platform is centered around a breakthrough technology that enables the rapid, comprehensive, and genome-wide identification of the peptide antigen targets of T cell receptors. This technology greatly enhances our ability to understand the specific antigens that drive important disease processes, including tumor cell recognition by the immune system, self-reactivity in autoimmune disorders, and acquired immunity in infectious disease. TScan is using the platform in oncology to discover new TCR/target pairs and to rapidly move novel TCRs into clinical development.
