Optimizing Engager T-cells for CD19+ Malignancies
Background
Using the patient's own immune system to fight cancers is a promising approach to improve outcomes for pediatric cancer patients who do not benefit from current therapies. However, the body's immune defenses against cancers often fail because the cancers do not induce or actively inhibit immunity. Cancer treatments consisting of the infusion of T cells (one component of the patient's own immune system) that recognize CD19, a molecule present on many blood cancers, have shown promise in early clinical studies.
Project Goals
We have developed a new strategy to produce CD19-specific T cells with a genetic approach that redirects not only the genetically modified cells, but also unmodified T cells to CD19-positive blood cancer cells. Preliminary studies have shown good activity against leukemia in preclinical models that closely mimic human disease. We now plan to build on our encouraging results, and will evaluate if additional genetic modifications of CD19-specific T cells and/or targeting additional molecules present on many blood cancers enhances anti-tumor activity. If our pre-clinical approach is successful and a clinical study is justified, we have the resources to develop such a study at our center.
