Neoadjuvant Tebentafusp in Patients With Metastatic Uveal Melanoma

"Patients will receive tebentafusp intravenously (IV) weekly for 6 months with liver directed imaging every 2 months to identify rapid progressors. Tebentafusp will be administered at 20 micrograms on W1D1, 30 micrograms on W2D1, and 68 micrograms once every week thereafter.~After 6 months, patients with complete response (CR) according to RECIST will continue tebentafusp therapy (surgery might be an option if deem appropriate by local PI); while patients achieving partial response or stable disease will be evaluated for tumor resection and will enter into Surgery phase. Surgery will be conducted 7 months (+/- 1 month). If progressioh disease (PD) occurs earlier surgery can happen earlier. After surgery, patients without pCR or R0 surgery will maintain tebentafusp until disease relapse, unacceptable toxicity or patient withdrawal. Patients with pCR and R0 will continue tebentafusp therapy for 1 additional year or until disease relapse, unacceptable toxicity or patient withdrawal."
