Dr. Till is developing novel lymphoma immunotherapies, based on adoptive T cell transfer.
- The primary project of the laboratory is development of a CD20-targeted chimeric antigen receptor (CAR) for use in human clinical trials for patients with CD20-expressing B cell malignancies. In addition to generation of a clinical-grade lentiviral vector expressing this construct and optimization of culture conditions, the lab is performing correlative experiments using specimens from patients treated with CAR T cell products to assess the in vivo expansion, persistence and functionality of adoptively transferred T cells.
- Other ongoing explorations are focused on costimulation in CAR T cells, particularly evaluating the extent to which costimulatory domains encoded as part of the CAR construct are sufficient to replace endogenous costimulatory signals.
- Ways to enhance in vivo function of CAR T cells through blockade or knockdown of checkpoint molecules are being pursued, focusing on expression of a secreted anti-CTLA4 construct designed to be expressed by CAR T cells in the tumor microenvironment, thus limiting systemic autoimmune toxicities.
- An immunocompetent model is being used to study the effects of CAR T cells on the endogenous immune system, particularly whether CAR T cell mediated tumor destruction can elicit adaptive immune responses and epitope spreading, and whether this process can be enhanced with the use of other immune adjuvant agents, either administered systemically or secreted by the T cells.
