Children’s Oncology Group (COG). A. Kim Ritchey is an active clinical investigator and local principal investigator (PI) for a number of COG trials at UPMC Children’s Hospital of Pittsburgh. The local PI of a COG trial is responsible for overseeing the research activity of that protocol at the institution. One such trial is testing the efficacy of the tyrosine kinase inhibitor dasatanib when it is added to standard chemotherapy for children with Philadelphia chromosome–positive acute lymphoblastic leukemia. This trial is partially funded by Bristol-Myers Squibb. Ritchey is involved with oversight of the development and performance of pediatric cancer clinical trials at the national level. He is a member of the National Cancer Institute (NCI) Pediatric Leukemia/Lymphoma Steering Committee, which reviews all COG proposals for clinical research in the areas of leukemia and lymphoma. As chair of the COG Data Safety Monitoring Committee, he leads the group which has oversight of all phase 2 and 3 clinical trials.

Ritchey served as local PI for the Pediatric Brain Tumor Consortium, a collaboration of 12 institutions funded by the NCI to offer potentially practice-changing Phase I research for children with brain tumors.
