Immunocore BLA for Melanoma Approved
FDA has approved an Immunocore BLA for Kimmtrak (tebentafusp-tebn) for treating certain adult patients with unresectable or metastatic uveal melanoma (mUM). Approval was based on data from the company’s Phase 3 IMCgp100-202 clinical trial, which evaluated overall survival (OS) of Kimmtrak compared to investigator’s choice (either pembrolizumab, ipilimumab, or dacarbazine) in patients with previously untreated mUM. “Data from the trial, the largest Phase 3 trial undertaken in mUM, showed that Kimmtrak demonstrated unprecedented median OS benefit as a first-line treatment,” the company says.
Kimmtrak is described by Immunocore as a novel bispecific protein comprised of a soluble T cell receptor fused to an anti-CD3 immune-effector function. It is designed to target gp100, a lineage antigen expressed in melanocytes and melanoma, it says. This is the first therapy developed using Immunocore’s ImmTAC technology platform that is designed to redirect and activate T cells to recognize and kill tumor cells.
