Phase IIA Single-Arm Study of Treatment of Patients With Advanced Liver Cancer With a Combination of TATE (Transarterial Tirapazamine Embolization) Followed by an Anti-PD-1 Monoclonal Antibody
This is a multi-center, open-label phase IIA study that investigates the preliminary efficacy of Trans-arterial Tirapazamine Embolization (TATE) treatment of liver cancer followed by a PD-1 checkpoint inhibitor (nivolumab). Patients with two types of cancers will be enrolled, advanced hepatocellular carcinoma (HCC),and metastatic gastric cancer. All enrolled patients need to have liver lesions and have progressed on a prior immune checkpoint inhibitor.
• Patients with a confirmed diagnosis of (1) advanced HCC or (2) metastatic gastric cancer.
• Patients between ages 18 and 80
• If HCC patients, they should have progressive disease (PD) on an immune therapy for advanced HCC. For patients with metastatic gastric cancer, they should have failed at least one line of systemic chemotherapy and an immune checkpoint inhibitor.
• Patients with liver tumor lesions with at least one with a diameter of 2 cm or bigger, which is amendable for (super-)selective TATE as the target lesion.
• ECOG score 2 or less
• Child-Pugh scores 5-7 for HCC patients
• All prior chemotherapy at least 4 weeks prior to study treatment. Immunotherapy not subject to this limitation.
• No major GI bleeding in the prior 2 months.
