What this trial studies

This phase 2 trial investigates the combination of stereotactic body radiotherapy (SBRT) and immunotherapy using Opdualag (nivolumab and relatlimab) for patients with metastatic uveal melanoma. Patients will receive SBRT in three doses of 15Gy each to target 1-5 metastases, while Opdualag will be administered every four weeks for up to two years. The study aims to evaluate the safety, tolerability, and response rates using iRECIST criteria, enrolling up to 50 patients. This approach seeks to explore the potential synergistic effects of combining radiation and immunotherapy in a condition with limited standard treatment options.

Who should consider this trial

Good fit: Ideal candidates include individuals with measurable metastatic uveal melanoma who meet specific health criteria and have not received certain prior therapies.

Not a fit: Patients with extensive liver tumor volume, active CNS metastases, or those who have previously received Opdualag or relatlimab may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with metastatic uveal melanoma.

How similar studies have performed: While there is limited data on this specific combination, previous studies have shown promise in using radiation and immunotherapy for various cancers, suggesting potential for success.
