About

Phase II trial to study the effectiveness of irofulven in treating patients who have metastatic breast cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

Full description

OBJECTIVES:

I. Evaluate the response rate and time to treatment failure in patients with refractory metastatic adenocarcinoma of the breast treated with irofulven.

II. Assess the qualitative and quantitative toxic effects of this drug in these patients.

III. Determine the population pharmacokinetics and the pharmacokinetics-pharmacodynamic relationships of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive irofulven IV over 30 minutes on days 1 and 15. Treatment continues every 28 days in the absence of disease progression or unacceptable toxicity.

Enrollment: 32 patients

Sex: All

Volunteers: No Healthy Volunteers
