liposomal daunorubicin in treating patients with metastatic breast cancer

Conditions: Breast Cancer

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. purpose: phase i trial to study the effectiveness of liposomal daunorubicin in treating patients who have metastatic breast cancer.

objectives: i. determine the maximum tolerated dose of daunorubicin liposomal in patients with metastatic breast cancer. ii. assess the antineoplastic activity and safety profile of this regimen in these patients. outline: this is a dose escalation study. patients receive daunorubicin liposomal iv over a minimum of 2 hours on day 1. treatment repeats every 3 weeks for a maximum of 8 courses in the absence of disease progression or unacceptable toxicity. cohorts of 3-6 patients receive escalating doses of daunorubicin liposomal until the maximum tolerated dose (mtd) is determined. the mtd is defined as the dose at which 2 of 6 patients experience dose limiting toxicity. patients with stable or responding disease are followed at 1 and 3 months, then every 3 months for 1 year. projected accrual: approximately 15-20 patients will be accrued for this study within 1 year.
