ACHELOIS - Key Persons


Dr. Cassian Yee

Job Titles:
  • Member of the Scientific Advisory Board
Dr. Yee is a pioneer in adoptive cell transfer (ACT) immunotherapy, which involves taking anti-cancer T cells from patients and then enhancing their anti-tumor capabilities before putting them back into patients. He pioneered several seminal first-in-human studies using a well-defined, uniform population of ex vivo expanded antigen-specific T cells to delineate the requirements for effective immune-based therapies. He helped establish standards for the process, demonstrated that these T cells can confer durable anti-tumor memory, and showed how checkpoint immunotherapy can enhance ACT's effects. Dr. Cassian Yee is the director of Solid Tumor Cell Therapy in the Center for Cancer Immunology Research and a professor in the Department of Melanoma Medical Oncology at the University of Texas MD Anderson Cancer Center. He has received numerous awards, including Clinical Translation Scientist Award from the Burroughs Welcome Fund and the Cancer Research Institute Immunotherapy Dream Team.
