Abstract
Uveal melanoma is the most common intraocular cancer in adults. Metastatic uveal melanoma has a poor prognosis. Tebentafusp-tebn is the first drug in the new immune mobilizing monoclonal T-cell receptors against cancer (ImmTAC) class of T cell-directed therapy. Tebentafusp-tebn has been shown in a randomized phase III clinical trial to lead to improved overall survival and progression-free survival when compared with single-agent pembrolizumab, ipilimumab, or dacarbazine in previously untreated human leukocyte antigen (HLA)-A*02:01-positive metastatic uveal melanoma patients. Tebentafusp-tebn is now approved by the US Food and Drug Administration in HLA-A*02:01-positive uveal melanoma patients as first-line therapy in the metastatic setting.
