Alternate Title

Mitoxantrone With or Without Docetaxel in Treating Women With Metastatic Breast Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase III Treatment Closed 80 and under Other GER-AIO-01/92 EU-93011, NCT00002544

Objectives

1. Compare the survival and quality of life scores (composed of time to progression, WHO performance status, subjective patient evaluation, and subjective adverse event profile) among women with metastatic breast cancer of unfavorable prognosis treated with mitoxantrone vs mitoxantrone plus docetaxel as first-line chemotherapy for metastatic disease.
2. Compare the remission rate, time to remission, remission duration, time to best response, objective adverse events, and patient acceptance of treatment on these 2 regimens.
3. Investigate which prognostic subgroups of women benefit from treatment.

Entry Criteria

Disease Characteristics:

• Histologically proven metastatic breast cancer of poor prognosis, defined by any of the following characteristics:

• Indication for chemotherapy documented by either:
  • Hormone receptor negativity

    OR

Expected Enrollment

A total of 300 patients will be accrued for this study.

Outline

This is a randomized, multicenter study. Patients are stratified according to age, treatment center, disease free interval (no more than 18 months vs more than 18 months), hormone receptor status (positive or unknown vs negative), prior adjuvant therapy with anthracyclines (yes vs no), presence of liver metastases (liver involvement as a single organ vs liver plus other organ involvement vs no liver involvement), and presence of lung metastases (yes vs no). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive mitoxantrone IV on day 1. Treatment repeats every 3 weeks until disease progression, unacceptable toxicity, or maximum cumulative dose. Patients who achieve complete response receive 2 additional courses.



• Arm II: Patients receive mitoxantrone IV plus docetaxel IV over 1 hour on day 1. Treatment repeats every 3 weeks for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity.

At relapse, reinduction with the original regimen is attempted. Following a second complete response, 2 additional courses of consolidative treatment are given, and patients are then followed off treatment.

Quality of life is assessed periodically.
