A Phase I, Open-Label, Dose-Escalating Study Of The Safety, Tolerability, And Anti-Tumor Activity Of A Single Intrahepatic Arterial Injection Of Genetically Engineered Herpes Simplex Virus, NV1020, In Subjects With Adenocarcinoma Of The Colon With Metastasis To The Liver

OBJECTIVES:

• Determine the safety and maximum tolerated dose of a single intrahepatic NV1020 injection in patients with hepatic metastases from colon cancer that has failed first-line chemotherapy.
• Determine the tolerability of this drug in these patients.
• Determine preliminarily the anti-tumor activity of this drug in these patients.
• Assess the immunogenicity of NV1020 in these patients.

OUTLINE: This is a dose escalation study.

Patients receive a single intrahepatic arterial injection of NV1020 over 10 minutes with the aid of hepatic arteriography.

Cohorts of 3 patients receive escalating doses of NV1020 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 patients experience dose-limiting toxicity.
