Immunocore Kimmtrak Achieves 16% Five-Year Survival Rate
Immunocore announced that Kimmtrak five-year overall survival, OS, was presented in an oral session at the American Association for Cancer Research, AACR, 2026 meeting. This is the longest, prospective Phase 3 randomized trial in patients with unresectable or metastatic uveal melanoma - a disease with a very poor prognosis and a historical survival rate of less than 5% at 5 years. Kimmtrak doubled the likelihood of being alive at five years, with an OS for Kimmtrak of 16% versus 8% in the control arm. These results also represent the longest follow-up reported for any T cell engager in a solid tumor.
