IFI investigator, Daniel J. Powell Jr., PhD has been selected by the Board of Directors from the American Society of Gene & Cell Therapy (ASGCT) for a 2014 Outstanding New Investigator Award. Dr. Powell was selected from a competitive field of nominations based upon his significant contributions to the field of gene and cell therapy. The award ceremony and presentation session were held during the 17th Annual Meeting in Washington, DC in May, and was attended by thousands of meeting participants.
The Powell Lab is developing innovative immunotherapy strategies built upon clinical observations and studies in basic T cell biology. Adoptive T cell therapy using naturally-occurring tumor infiltrating lymphocytes (TILs) or peripheral blood T cells genetically modified to express a chimeric antigen receptor (CAR) can mediate comprehensive cancer elimination in patients, provided that highly avid, tumor antigen-specific T cells with the ability to proliferate and persist after infusion can be identified. We recently overcame one obstacle to widespread TIL therapy by showing that naturally-occurring tumor-reactive T cells in various cancers can be identified by their cell surface expression of the TNFR superfamily receptor, CD137, demonstrating a role for CD137 in the immunobiology of cancer. To instill T cells with enhanced ability to persist after infusion, we recently applied CAR technology as a tool to test the impact of various costimulatory signals on human CAR T cell survival following antigen encounter in vivo, and discovered a functional role for CD27 in human T cell memory formation. We also devised a novel dual CAR T cell approach where the TCR signal is dissociated from costimulatory signals in two independent CARs of distinct antigen specificity, thus delivering tumor-focused activity while comparatively sparing normal healthy tissues expressing a low level of single antigen. Lastly, to develop widespread T cell therapy, we pioneered a universal immune receptor approach that is adaptable in antigen specificity, allowing for highly personalized T cell generation based upon the repertoire of antigens expressed by each individual’s cancer cells. These strategies build on the early success of adoptive immunotherapy by addressing significant hurdles to otherwise safe and effective T cell therapy.
