O6-benzylguanine and Carmustine in Treating Patients With Unresectable Locally Recurrent or Metastatic Melanoma

Melanoma (Skin) Clinical Trial

Official title: A Phase II Trial of O6-Benzylguanine (NSC 637037) and BCNU (Carmustine) in Patients With Metatstatic Melanoma

Status Completed

Clinical Trial Summary

Phase II trial to study the effectiveness of O6-benzylguanine and carmustine in treating patients who have unresectable locally recurrent or metastatic melanoma. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than once chemotherapy drug may kill more tumor cells.

Clinical Trial Description

OBJECTIVES:

I. Determine the objective clinical response rate and duration of response in patients with unresectable locally recurrent or metastatic melanoma treated with O6-benzylguanine and carmustine.

II. Compare the toxicities of this regimen in patients with no prior chemotherapy vs prior chemotherapy failure.

III. Correlate clinical response to this regimen in these patients with O6-alkylguanine DNA alkyltransferase (AGT) depletion and baseline AGT in peripheral blood mononuclear cells and tumor tissue.

OUTLINE: This is a multicenter study. Patients are stratified according to prior chemotherapy (chemotherapy failure vs chemotherapy naive).

Patients receive O6-benzylguanine IV over 1 hour, followed 1 hour later by carmustine IV over 1 hour on day 1. Treatment continues every 6 weeks for a minimum of 2 courses in the absence of disease progression or unacceptable toxicity.

Patients with disease progression are followed every 6 months. All other patients are followed every 3 months for 1 year. ;
