My research is dedicated to developing gene-engineered cell therapies that target cancer cells in animal models of cancer. The goal of this research is to identify optimal cell therapies that can then be evaluated in cancer patients. As a former Principal Investigator of a clinical trial using genetically engineered T cells targeted against malignant B cells, I witnessed the potential for this as a cancer immunotherapy. Its my hope that our innovative laboratory and clinical research here at the Moffitt Cancer Center will lead to similar therapeutic options for patients with other cancers.

The Davila laboratory is interested in the development of T cell therapies for cancer. One such therapy involves chimeric antigen receptors (CAR) that can target hematologic and solid tumor malignancies. Recent clinical trials have demonstrated the potential of targeting the CD19 antigen for B cell malignancies with CAR T cells. These trials have demonstrated that an acute B cell malignancy, B cell acute lymphoblastic leukemia (B-ALL), is tremendously responsive. These early Phase trials, while exciting, leave many questions to be answered, which oftentimes is best done in pre-clinical animal models. There are three major research projects in the laboratory. 1. We have created a syngeneic mouse model of B-ALL using the Eμ-ALL cell line (Davila et al PLOS ONE 2013), which was derived from the Eμ-myc transgenic mouse prone to B cell malignancies. Our Eμ-ALL mouse model allows the evaluation of important mechanisms involving the targeting of B cell malignancies with mouse CAR T cells in fully immunocompetent animals. Using this model we are a) evaluating the biology behind activation and costimulation of CAR T cells. 2. We recognize that targeting CD19, and thereby B cell malignancies, is just the beginning of this new field and we are developing new CARs against other hematologic and solid tumor malignancies. Our initial focus is to develop CARs against Acute Myeloid Leukemia (AML), which has well-defined antigens that have been previously targeted with therapeutic monoclonal antibodies. However, responses to these antibodies, as well as pre-clinical studies involving CARs targeting these same antigens, demonstrate safety concerns due to the shared expression of the antigens on hematopoietic stem cells and/or granulocytes. Therefore we are engineering safety mechanisms to avoid this dangerous off-target toxicity. 3. We also recognize that some cancer may not be suitable for targeting with a CAR. Therefore, in collaboration with other investigators at Moffitt we are refining and optimizing the production of tumor-infiltrating lymphocytes (TILs) from solid tumor metastases. Our goal is to rapidly develop and re-infuse these TILs back into patients.
