Clinical trials

Patients with refractory metastatic colorectal cancer or non-small cell lung cancer with liver metastasis treated with Trans-arterial Tirapazamine Embolization along with Pembrolizumab.

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.

This phase 1 study is to determine the optimal dose and tolerability of a hypoxia-activating agent, tirapazamine, when it is combined with embolization in liver cancer. Liver cancer patients who are Child-Pugh score A, suitable for embolization with tumor no more than 4 nodules are eligible. Tirapazamine will be given by intra-arterial injection before embolization. Treatment effect is evaluated by MRI based on mRECIST criteria. Repeat treatment is necessary only if disease progression. Dose escalation cohort has been completed. Expansion cohort is open for metastatic liver dominant neuroendocrine tumor.
