Umbilical Cord Blood Transplant for Hematological Malignancies

The main study intervention includes CD3/CD28 ex vivo costimulated T cells derived from a thawed umbilical cord blood unit, co-infused following a myeloablative conditioning regimen.

Activated T cells are T cells that have been activated in the laboratory by exposure to 2 compounds or molecules called CD3 and CD28; when T cells are exposed to both of these compounds at the same time, they become activated or "stimulated" and may be more effective in fighting infections, cancer cells, and promoting the recovery of red cells, white cells, and platelets after transplantation. At the Hospital of the University of Pennsylvania, activated T cells are prepared at the Clinical Cell and Vaccine Production Facility, also known as the CVPF.
