Hepzato Kit and Opdualag for Metastatic Melanoma and Liver Metastasis

Summary

This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) in the first line setting in patients with metastatic melanoma with liver metastasis is safe, tolerable, and will have a synergistic effect leading to improved clinical outcomes compared to the historic cohort of patients with liver metastasis treated with combination immune checkpoint inhibitor therapy.

Detailed description

Co-Primary Objectives * To evaluate the safety and tolerability of HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™) in subjects with metastatic melanoma and liver metastasis (LM). * To evaluate the preliminary systemic efficacy of HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™), as measured by objective response rate (ORR), in subjects with metastatic melanoma and LM. Secondary Objectives * To evaluate the preliminary systemic efficacy of HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™), as measured by ORR, in both hepatic and non-hepatic target lesions in subjects with metastatic melanoma and LM. * To evaluate the disease control rate (DCR) in subjects with metastatic melanoma and LM receiving HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™). * To evaluate the PFS in subjects with metastatic melanoma and LM receiving HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™). * To evaluate the overall survival (OS) in subjects with metastatic melanoma and LM receiving HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™). * To evaluate the duration of response (DOR) in subjects with metastatic melanoma and LM receiving HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™). * To evaluate the tumor reduction at any time during treatment in subjects with metastatic melanoma and LM receiving HEPZATO KIT™ in combination with nivolumab and relatlimab (Opdualag™).
