Clinical Trial Summary

RATIONALE: Inserting a modified herpesvirus gene into a person's melanoma cells may make the cancer more sensitive to the antiviral agent ganciclovir.

PURPOSE: Phase I trial to study the effectiveness of gene therapy in treating patients who have stage IV melanoma.

Description:

OBJECTIVES: I. Determine the maximum tolerated dose of ganciclovir administered IV every 12 hours for 7 days in combination with adenovirus RSV-TK administered by direct intralesional injection in patients with cutaneous or subcutaneous metastatic malignant melanoma. II. Determine the dose limiting toxicities of this regimen in this patient population. III. Evaluate the response (both local and at distant metastatic sites), duration of response, response by ganciclovir dose, and any impact local treatment with adenovirus RSV-TK and ganciclovir "suicide" gene therapy may have on overall survival in these patients.

OUTLINE: This is a dose escalation study of ganciclovir. Patients are stratified according to response of the index lesion and other metastatic disease sites. Patients receive an intratumoral injection of adenovirus RSV-TK on day 1. Ganciclovir IV is administered every 12 hours on days 3-10 for a total of 14 doses. Patients sustaining a partial response (PR) or complete response (CR) may be retreated 2 weeks after documented PR or CR. Cohorts of 3-6 patients receive escalating doses of ganciclovir until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities. Patients are followed at 3 weeks, 4 weeks, 60 days, then every 2 months for 6 months, and then every 3 months for 1.5 years.

PROJECTED ACCRUAL: A maximum of 27 patients will be accrued for this study.
