The drug is tebentafusp-tebn (Kimmtrak, from Immunocore Limited), which acts as a bispecific gp100 peptide-HLA-directed CD3 T-cell engager. It is the first of a novel class of T-cell receptor (TCR) bispecific immunotherapies under development at the company.
It is also the first and only therapy for the treatment of unresectable or metastatic uveal melanoma to be approved by the FDA, and it is the first therapy to demonstrate a survival benefit to patients with this disease. However, the indication specifies that the drug is for use only in patients who are HLA-A*02:01-positive.
