Theodore W. Laetsch, MD is an Associate Professor in the Department of Pediatrics and Member of the Harold C Simmons Comprehensive Cancer Center at the University of Texas Southwestern Medical Center in Dallas, TX. He also leads the Experimental and Cellular Therapeutics Program (ECTP) and the Cellular Therapeutics in the Gill Center for Cancer and Blood Disorders at Children’s Health. Dr. Laetsch also serves as the Rare Tumors Disease Committee Chair for the Children’s Oncology Group.  Dr. Laetsch received a BS in Agricultural and Biosystems Engineering from the University of Arizona and then a MD from the University of California, San Francisco. Dr. Laetsch completed his residency at the University of Colorado/Children’s Hospital Colorado, where he also served as chief resident. He completed his fellowship training and an instructorship at the Children's Hospital of Philadelphia (CHOP), where he conducted translational laboratory research focused on mechanisms to restore apoptotic signaling in neuroblastoma. In 2013, he joined the faculty at UT Southwestern. Dr. Laetsch conducts both early phase clinical and translational laboratory-based research testing potential novel therapeutics in high-risk pediatric solid tumors with a goal of “bridging the gap” between laboratory research and early phase clinical trials. As the leader of the ECTP program, Dr. Laetsch serves as the PI of several phase 1 and phase 2 studies of new targeted agents and cellular therapies for children with relapsed or refractory cancer. Dr. Laetsch has a strong interest in the use of tumor molecular profiling to guide therapy. In addition to these research activities, Dr. Laetsch continues to see children with cancer in the clinic at Children’s Medical Center.
