CAR-T cells are a new therapy where a patient’s own white blood cells are isolated, modified in a dish to better recognize their tumor, and infused back in. These engineered T cells have transformed the treatment of blood cancers and are being actively considered for solid tumors such as triple-negative breast cancer (TNBC) and ovarian cancer. Unfortunately, CAR-T cell treatment success has been limited partly because these cells eventually lose their ability to control tumors in a process called T cell exhaustion. Understanding why CAR-T cells become exhausted in solid tumors is absolutely required to improve patient outcomes and get better immune-targeted treatment responses. These dysfunctional T cells show many defects, including overproduction of a receptor known as PD-1 that inhibits T cells. It is not currently known why high levels of PD-1 are found on exhausted CAR-T cells and what the consequences of high PD-1 expression are. We hypothesize that by focusing on exhaustion-specific regulation, we can rewire CAR-T cells to prevent PD-1 mediated dysfunction in tumors while minimizing side-effects. These will be attractive targets for translation to early-phase CAR-T clinical trials in breast cancer, ovarian cancer, and other solid tumors, where there is intense interest in reducing T cell exhaustion.
The research project that receives the highest rating by the Scientific Advisory Committee is annually designated as the Abeloff V Scholar. This award is in honor of the late Martin D. Abeloff, MD, a beloved member of the Scientific Advisory Committee.
