What this Trial Is About

Researchers are studying the potential of tebentafusp as an additional treatment following the primary treatment of high-risk uveal melanoma, a type of eye cancer. This trial focuses on patients who have undergone surgery or radiotherapy for non-metastatic uveal melanoma but are at high risk of cancer recurrence. Tebentafusp is the first drug shown to improve survival in patients with metastatic uveal melanoma, and this study explores whether it can reduce the risk of disease recurrence when given after initial treatment. Participants assigned to the treatment group will receive weekly intravenous infusions of tebentafusp, starting with 20 mcg in the first week, then 30 mcg in the second week, followed by 68 mcg in the third week and continuing with this dose weekly for up to 6 months (maximum 26 infusions). Another group will be observed without additional treatment to compare outcomes. The study is randomized and open-label, meaning participants are assigned to groups by chance and both researchers and participants know the assigned treatment. During the study, participants will be closely monitored for recurrence-free survival over approximately 8 years, along with overall survival, occurrence of adverse events, and quality of life. Assessments include imaging to confirm no cancer recurrence before starting, regular health evaluations, and safety monitoring. Participants will be followed for long-term outcomes to understand the effects of tebentafusp as an adjuvant therapy in this setting.
