How KIMMTRAK Works

Tebentafusp-tebn works by bridging T cells and tumor cells to facilitate an immune response. The molecule's T cell receptor arm binds to a gp100 peptide presented by HLA-A*02:01 on the surface of uveal melanoma cells. This interaction activates polyclonal T cells to release inflammatory cytokines and cytolytic proteins, resulting in the direct lysis of the tumor cells.
