Dose-defining Study of Tirapazamine Combined With Embolization in Liver Cancer

Summary

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.

Eligibility

Inclusion Criteria:

1. Patients with well-differentiated NET and liver-dominant metastatic disease with intrahepatic disease progression, regardless of primary tumor origin or tumor functional status. Patients may have extrahepatic lesions as long as the majority of the disease burden is intrahepatic.
2. No limitation in hepatic lesion tumor size or number but the total volume of liver tumors cannot exceed 50% of the liver volume.
3. Patients are allowed to have prior US Food and Drug Administration (FDA)-approved treatments, including systemic therapies, surgery, ablation, or transarterial therapies for the metastatic NET.
4. Age 20 or higher, ECOG functional status 0-1, and with no known major cardiac, pulmonary, or renal dysfunction.
5. Are candidates for TAE or TACE and without portal vein occlusion per treating interventional radiologists.
6. ANC no less than 1000 /μL. Hemoglobin ≥ 9 gm/dL. Platelets no less than 50,000 /μL. Creatinine no more than 2.0 mg/dL. AST, ALT no more than 5X upper limit of normal. Bilirubin no more than 2.5 mg/dl. PT prolongation ≤ 4 sec above upper limit of normal.
7. Woman of child-bearing potential (WOCBP) should use highly effective contraception during trial participation and for 6 months after the last dose of tirapazamine and men who are partners with WOCBP should use highly effective contraception, including barrier contraception, during trial participation and for 3 months after the last dose of tirapazamine.
