    Tebentafusp, sold under the brand name Kimmtrak, is an medication used to treat a type of eye cancer, known as uveal melanoma.[1] It is used in HLA-A*02:01-positive cases that cannot be managed by surgery alone.[1][5] It is given by injection into a vein.[1] Due to the risk of side effects nearly a day of monitoring is required after the initial doses.[1]

    Common side effects include cytokine release syndrome, rash, fever, itching, tiredness, nausea, abdominal pain, swelling, low blood pressure, dry skin, headache, and vomiting.[1] Use in pregnancy may harm the baby.[1] It is a bispecific gp100 peptide-HLA-directed CD3 T cell engager.[1]

    Tebentafusp was approved for medical use in the United States and Europe in 2022.[1][5] In the United States the medication costs about 18,800 USD per dose.[6] While available in the United Kingdom, the cost is yet to be determined.[6]

    Medical uses

    Tebentafusp is indicated for HLA-A*02:01-positive adults with unresectable or metastatic uveal melanoma.[1][4][7]

    It improves typical survival over standard treatment from 16 months to to 22 months.[5]

    Dosage

    The initial dose is typically 20 mcg, followed by 30 mcg on day 8 and 68 mcg on day 15 followed by 68 mcg weekly after that.[1]

    History

    Efficacy was evaluated in IMCgp100-202 (NCT03070392), a randomized, open-label, multicenter trial of 378 participants with metastatic uveal melanoma.[4] Participants were required to be HLA-A*02:01 genotype positive identified by a central assay.[4] Participants were excluded if prior systemic therapy or localized liver-directed therapy were administered.[4] Prior surgical resection of oligometastatic disease was permitted.[4] Participants with clinically significant cardiac disease or symptomatic, untreated brain metastases were excluded.[4]

    The U.S. Food and Drug Administration (FDA) granted Immunocore's application for tebentafusp priority review, breakthrough therapy, and orphan drug designations.[4]

    Society and culture

    On 24 February 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Kimmtrak, intended for the treatment of uveal melanoma.[8][9] The applicant for this medicinal product is Immunocore Ireland Limited.[8][9] Tebentafusp was approved for medical use in the European Union in April 2022.[5]
