Summary

This study is a multicenter, open label phase I/ II trial to assess the safety and clinical efficacy of tebentafusp-tebn in combination with liver-directed therapies in HLA-A\*0201 positive patients with metastatic uveal melanoma. In Part 1 of the study, the Prinicipal Investigator will investigate the safety and efficacy of tebentafusp-tebn in combination with hepatic IE in patients with a low to moderate hepatic disease burden. In Part 2, the study will investigate the efficacy of tebentafusp-tebn in combination with TACE in patients with bulky hepatic disease.

Conditions

  • Metastatic Uveal Melanoma

Interventions

DRUG

Tebentafusp-Tebn

Dosing: All patients enrolled in this study will receive treatment with tebentafusp-tebn based on the approved step-up dosing regimen of 20 mcg on C1D1, 30 mcg on C1D8, then 68 mcg weekly beginning on C1D15 and thereafter. This escalated dose administered at C1D15 will be the dose used for the remainder of the treatment period unless dose reduction is implemented for toxicity. Beginning with C1D8, tebentafusp-tebn will be administered on the scheduled day (± 2 days), and consecutive infusions of tebentafusp-tebn must be administered at least 5 days apart.

DRUG

GM-CSF (Sargramostim)

Recombinant human GM-CSF (Sargramostim, Leukine®, Sanofi US) 1,500mg will be mixed with ethiodized oil (Ethiodol®). The GM-CSF/ethiodized oil mixture will be injected selectively into one of the hepatic lobes, followed by infusion of gelatin sponge particles to achieve the stasis of blood flow. This will repeat every 4 weeks.

DRUG

BCNU

Patients will be treated with hepatic artery infusion of 300mg BCNU (1,3-bis \[2-chloroethyl\]-1-nitrosourea, Carmustine) dissolved in ethiodized oil followed by embolization with gelatin sponge particles \[TACE with BCNU 300mg\]; every 4 weeks +/- 7 days in the case of either bilobar or unilobar metastasis
