Tebentafusp (Kimmtrak) is a bispecific fusion protein, comprised of a T cell receptor (TCR) fused to an antibody fragment with specificity for the CD3 (cluster of differentiation 3) receptor, found on polyclonal T cells. The TCR has specificity for a gp100 peptide (expressed preferentially in melanoma cells) presented by human leukocyte antigen‑A*02:01 (HLA‑A*02:01). In vitro, tebentafusp bound to HLA‑A*02:01‑positive uveal melanoma cells and activated polyclonal T cells to release inflammatory cytokines and cytolytic proteins, which results in direct lysis of uveal melanoma tumour cells. Kimmtrak is indicated for the treatment of HLA‑A*02:01‑positive adult patients with unresectable or metastatic uveal melanoma. Kimmtrak concentrate for intravenous infusion contains tebentafusp 0.1 mg per 0.5 mL and is available in packs of 1 vial.
