Jerome Ritz, MD

Dr. Ritz is currently Professor of Medicine in the Department of Medical Oncology at the Dana-Farber Cancer Institute, Brigham and Woman’s Hospital and Harvard Medical School.

His research laboratory focuses on the assessment of donor immune function after allogeneic hematopoietic stem cell transplantation (HSCT) and characterization of immune mechanisms responsible for graft versus leukemia (GVL) and graft versus host disease (GVHD). These laboratory studies have led to new clinical approaches to enhance GVL and prevent or treat GVHD. His lab also studies other cellular therapies for hematologic malignancies including CAR-T cells and activated NK cells. Working closely with clinical collaborators he has developed approaches to precisely characterize the effects of these treatments on immune function in vivo. These results are correlated with clinical outcomes such as response and toxicity to develop a better understanding of the immunologic mechanisms that contribute to these outcomes.

Dr. Ritz is also the Executive Director of the Connell and O’Reilly Families Cell Manipulation Core Facility at DFCI. This GMP cell manufacturing facility supports both adult and pediatric hematopoietic stem cell transplant programs at DFCI, Brigham and Women’s Hospital and Boston Children’s Hospital and also provides a variety of novel cellular products for patients enrolled on clinical trials at DFCI and affiliated hospitals. This facility recently expanded to include 15 cleanrooms available to manufacture a variety of cellular products including genetically modified stem cells, genetically modified immune cells, regulatory T cells, natural killer cells and other complex cellular products. This facility is a critical resource for both academic investigators and industry sponsors interested in developing innovative cellular therapies.
