Dr. Siddiqi is an associate professor in the Department of Hematology/Hematopoietic Cell Transplantation and Director of the chronic lymphocytic leukemia (CLL) program at COH. As an active member of the Toni Stephenson Lymphoma Center and the Immunotherapy Center at COH, she has been the institutional and, for some studies, national principal investigator of many phase 1, 2 and 3 clinical trials involving novel targeted therapies and cellular therapeutics such as chimeric antigen receptor (CAR) T cells in CLL and non-Hodgkin lymphomas. She works closely with Cancer Therapy Evaluation Program (CTEP), cooperative groups, and pharmaceutical companies on important clinical trials in order to bring novel, potentially lifesaving, therapeutics to our patients. As of June 1, 2021, she will be the Lymphoma Medical Director at the Irvine campus, set up open August 2022, which puts her in an ideal position to open impactful hematology clinical trials at CAN sites, starting with Orange county.
