Metastatic Uveal Melanoma in the Liver

The purpose of this study is to determine the effects (good and bad) that Tebentafusp in combination with Yttrium-90 (Y-90) radioembolization has on patients with metastatic uveal melanoma that has spread to the liver.

A recent clinical trial found that after 36 months, patients taking tebentafusp had a median survival of 21.6 months, compared to 16.9 months for those in the control group. Since recruitment for tebentafusp in metastatic uveal melanoma (mUM) has ended, a new trial is starting to test whether adding IL-2 can help overcome resistance to tebentafusp and improve its effectiveness. This study aims to answer: 1. Can combining tebentafusp with IL-2 improve tumor response and overall survival? 2. What are the benefits and side effects of this combination therapy? All participants will receive both IL-2 and tebentafusp in a 28-day treatment cycle. The dosing schedule is as follows: Cycle1: Day1-3 IL-2 Day4 Tebentafusp Day 10 IL-2 Day 11 Tebentafusp Day 17 IL-2 Day 18 Tebentafusp Day 24 IL-2 Day 25 Tebentafusp Cycle 2 \& thereafter Day 1 IL-2 Day 2 Tebentafusp Day 8 IL-2 Day 9 Tebentafusp Day 15 IL-2 Day 16 Tebentafusp Day 22 IL-2 Day 23 Tebentafusp
