Vinorelbine With or Without Trastuzumab in Treating Women With Progressive Metastatic Breast Cancer

June 21, 2013 updated by: Southwest Oncology Group

A Randomized Study of Weekly Vinorelbine (Navelbine®) Alone or in Combination With Trastuzumab (Herceptin®) (NSC-688097) for Patients With HER-2-Positive Metastatic Breast Cancer Whose Tumors Have Progressed After Taxane + Trastuzumab Combination Therapy - Phase III

RATIONALE: Drugs used in chemotherapy, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Trastuzumab may also help vinorelbine work better by making tumor cells more sensitive to the drug. Giving vinorelbine together with trastuzumab may be an effective treatment for breast cancer. It is not yet known whether giving vinorelbine together with trastuzumab is more effective than vinorelbine alone in treating breast cancer.

PURPOSE: This randomized phase III trial is studying vinorelbine and trastuzumab to see how well they work compared to vinorelbine alone in treating women with progressive metastatic breast cancer.

Detailed Description

OBJECTIVES:

  • Compare progression-free survival (PFS) of women with HER2-positive progressive metastatic breast cancer treated with vinorelbine with or without trastuzumab (Herceptin®).
  • Compare overall survival and time to treatment failure in patients treated with these regimens.
  • Compare the toxicity of these regimens in these patients.
  • Compare the response rate (complete and partial, confirmed and unconfirmed) in patients with measurable disease treated with these regimens.
  • Correlate baseline circulating tumor cells (CTC) with PFS, overall survival, and disease progression status at 9 weeks in patients treated with these regimens.
  • Correlate 4-week CTC with subsequent PFS and overall survival of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive trastuzumab (Herceptin®) IV over 90 minutes and vinorelbine IV over 10 minutes on day 1 of course 1. Patients receive trastuzumab IV over 30 minutes and vinorelbine IV over 10 minutes on days 1, 8, 15, and 22 in all subsequent courses. If trastuzumab is discontinued due to toxicity, patients may continue to receive vinorelbine alone.
  • Arm II: Patients receive vinorelbine IV over 10 minutes on days 1, 8, 15, and 22.

In both arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months until disease progression and then every 6 months for up to 3 years.

PROJECTED ACCRUAL: A total of 292 patients (146 per treatment arm) will be accrued for this study within 3 years.
