Leukemia Patients Remain in Remission More Than Two Years After Receiving Genetically Engineered T Cell Therapy
From
Nine of twelve leukemia patients who received infusions of their own T cells after the cells had been genetically engineered to attack the patients’ tumors responded to the therapy, which was pioneered by scientists in the Perelman School of Medicine at the University of Pennsylvania. Penn Medicine researchers will present the latest results of the trial today at the American Society of Hematology’s Annual Meeting and Exposition.
The clinical trial participants, all of whom had advanced cancers, included 10 adult patients with chronic lymphocytic leukemia treated at the Hospital of the University of Pennsylvania (HUP) and two children with acute lymphoblastic leukemia treated at the Children’s Hospital of Philadelphia. Two of the first three patients treated with the protocol at HUP – whose cases were detailed in the New England Journal of Medicine and Science Translational Medicine in August 2011 – remain healthy and in full remissions more than two years after their treatment, with the engineered cells still circulating in their bodies. The findings reveal the first successful and sustained demonstration of the use of gene transfer therapy to turn the body’s own immune cells into weapons aimed at cancerous tumors.
