PHILADELPHIA - Researchers from the Perelman School of Medicine at the University of Pennsylvania and The Children's Hospital of Philadelphia (CHOP) will present the latest advances from their studies of personalized cellular therapies for blood cancers during the 58th Annual Meeting of the American Society of Hematology (ASH) in San Diego.
Highlights include early results from a study of chimeric antigen receptor (CAR) T cells engineered to target B-Cell Maturation Antigen (BCMA) in patients with multiple myeloma, and a 100 percent response rate among relapsed/refractory acute lymphoblastic leukemia (ALL) patients treated with a humanized version of CAR T cell therapy who had not received any type of personalized cellular therapy previously. Investigators will also present results from the first global multisite study of the cellular therapy known as CTL019 in pediatric and young adult patients with relapsed/refractory ALL, showing a high level of efficacy and a similar safety profile to that shown in the first trials of the therapy at CHOP. The team will present results from more than 50 patients treated at 25 sites across the world.
The latest study results build on Penn's work as leader in CAR T cell therapies, dating back to the start of the first Penn clinical trial of CTL019 for patients with chronic lymphocytic leukemia in 2010. The research team is led by Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in the Perelman School of Medicine at the University of Pennsylvania, and Director of the Center for Cellular Immunotherapies in Penn's Abramson Cancer Center.
Additional abstracts will also be presented related to animal studies to improve efficacy of CAR T cell therapies and decrease side effects associated with the treatments, and research on biomarkers to distinguish between sepsis and cytokine release syndrome following treatment with these personalized cellular therapies.
