Interleukin-12 and Interferon Alfa in Treating Patients With Metastatic Malignant Melanoma

Recurrent Melanoma Clinical Trial

Official title: Phase II Trial of Interleukin-12 (NSC #672423, IND #6798) Followed by Interferon Alfa-2B in Patients With Metastatic Malignant Melanoma

Status Completed

Clinical Trial Summary

Phase II trial to study the effectiveness of combining interleukin-12 and interferon alfa in treating patients who have metastatic malignant melanoma. Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Interferon alfa may interfere with the growth of the cancer cells. Combining interleukin-12 and interferon alfa may kill more tumor cells.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To estimate the clinical response rates in patients with metastatic malignant melanoma treated with rhIL-12 and interferon alfa-2b.

II. To estimate the progression-free survival in patients with metastatic malignant melanoma treated with rhIL-12 and interferon alfa-2b.

SECONDARY OBJECTIVES:

I. To measure serum levels of interferon-gamma. II. To measure levels of JAK-STAT signaling intermediates in patient PBMCs and tumor samples.

III. To analyze interferon-alpha-induced STAT signaling in patient PBMCs. IV. To determine the expression of IFN-regulated genes in patient PBMCs and tumor tissues.

V. To determine the pattern of gene expression induced by treatment with IL-12 and interferon-alpha using DNA microarray techniques in patient PBMCs.

OUTLINE: This is a multicenter study.

Patients receive interleukin-12 IV over 5-15 seconds on day 1 and interferon alfa subcutaneously on days 2-6. Treatment repeats every 2 weeks in the absence of unacceptable toxicity. Patients are reassessed after 6 courses. Patients with a complete response receive 2 additional courses. Patients with a partial response or stable disease continue treatment in the absence of disease progression.

Patients are followed every 3 months for 1 year and then every 6 months for 1 year. ;
