A Phase I Clinical Trial of Intrahepatic Artery Delivery of TG6002 in Combination with Oral 5-Fluorocytosine in Patients with Liver-Dominant Metastatic Colorectal Cancer.

ABSTRACT:

Purpose

Effective treatment for patients with metastatic cancer is limited, particularly for those with colorectal cancer with metastatic liver lesions, in which accessibility to numerous tumors is essential for favorable clinical outcomes. Oncolytic viruses (OV) selectively replicate in cancer cells; however, direct targeting of inaccessible lesions is limited when using conventional intravenous or intratumoral administration routes.

Patients and methods

We conducted a multicenter, dose-escalation, phase I study of vaccinia virus, TG6002, via intrahepatic artery (IHA) delivery in combination with the oral prodrug 5-fluorocytosine to 15 patients with metastatic colorectal cancer.

Results

Successful IHA delivery of replication-competent TG6002 was achieved, as demonstr
