AI-designed proteins outperform existing CAR T designs against BCMA tumors in mice

CAR T cell therapy, which involves genetically modifying a patient's own immune cells to fight cancer, is a technique that has shown great promise, especially against blood cancers. But currently, only about 4% of patients with advanced or metastatic cancer in the United States are candidates for CAR T therapy, and closer to 3% will actually benefit, according to one recent analysis.

The lab of computational biologist Caleb Lareau, Ph.D., at Memorial Sloan Kettering Cancer Center (MSK), aims to broaden the impact of CAR T cell therapy and other cancer treatments by using generative artificial intelligence (AI) to design better “binders”—proteins that recognize and latch onto cancer cells, allowing the immune system to destroy them.

A proof-of-concept study, conducted in mouse models and published in Nature Biomedical Engineering, found MSK’s AI-driven approach significantly outperformed binders found on existing CAR Ts approved by the U.S. Food and Drug Administration (FDA) to target a protein called BCMA.
