Study Endpoints

Primary Endpoints

Regression of primary uveal melanoma after Tebentafusp treatment in 20% of treated patients.
3 months post-eye treatment

Regression is defined as ≥ 20% reduction in tumor volume. All estimates of rates will be presented with corresponding 95% exact confidence intervals. For regression rate, the method of Atkinson and Brown will be used to allow for the two-stage design.

Secondary Endpoints

Incidence of adverse events (AEs)
Up to 5 years
Detection of plasma circulating tumor-derived deoxyribonucleic acid (ctDNA) and correlation of antitumor response
22 months
Detection of aqueous humor ctDNA and correlation of antitumor response
22 months

Neoadjuvant Tebentafusp in Patients Locally Advanced, Unresectable Primary Uveal MelanomaEXPERIMENTALTebentafusp administration: 20mcg on Day 1, 30mcg on Day 8, 68 mcg on Day 15, and weekly doses of 68 mcg thereafter. Eye evaluations including clinical examination, ophthalmic ultrasound, optical coherence tomography, and wide-angle fundus imaging will be performed at baseline, Cycle 1 day 1, Cycle 1 day 8, Cycle 2 day 1, prior to definitive treatment for primary uveal melanoma (post-Tebentafusp), and at post-eye treatment evaluation at 3 months. Additionally optical coherence tomography angiography, autofluorescence, fluorescein angiography and MRI orbit will be performed at baseline, post-tebentafusp, and at post-eye treatment evaluation. Blood circulating tumor-derived DNA will be performed at baseline, Cycle 2 day 1, post-Tebentafusp, and at post-eye treatment evaluation at 3 months. Primary eye tumor biopsy (collected by fine-needle aspiration) and aqueous circulating tumor-derived DNA will be performed at baseline and post-Tebentafusp.
