About

RATIONALE: Inserting the gene for interleukin-12 into a person's skin tumor cells may make the body build an immune response to kill tumor cells.

PURPOSE: Phase I trial to study the effectiveness of interleukin-12 gene therapy in treating patients who have skin metastases.

Full description

OBJECTIVES:

• Determine the safety and toxicity of interleukin-12 gene in patients with spontaneous skin metastases.
• Determine the antitumor immune response in patients treated with this regimen.
• Compare the toxicity of this regimen administered for 1 week vs 2 weeks in these patients.
• Compare the local and systemic antitumor response in patients treated with this regimen administered for 1 week vs 2 weeks.

OUTLINE: Patients are stratified according to number of tumor sites (1 vs 2 vs 3 or more). Patients are assigned to 1 of 2 treatment arms.

• Group A: Patients receive interleukin-12 gene intratumorally over 5 minutes on days 1, 3, and 5.
• Group B: Patients receive IL-12 gene intratumorally over 5 minutes on days 1, 3, 5, 8, 10, and 12.

Patients with stable or responding disease may receive 1 subsequent course beginning on day 29.

Patients are followed at 3, 6, and 12 months.

PROJECTED ACCRUAL: A total of 12 patients (6 per treatment group) will be accrued for this study.

Sex: All

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers
