Alternate Title

Trastuzumab and Capecitabine in Treating Women With Metastatic Breast Cancer

Basic Trial Information

Objectives

Primary

1. Determine the median survival time and 2-year survival rate in women with taxane- and anthracycline-refractory HER2/neu-overexpressing metastatic breast cancer treated with trastuzumab (Herceptin®) and capecitabine.

Secondary

1. Determine the progression-free survival of patients treated with this regimen.
2. Determine the response rate in patients treated with this regimen.
3. Determine the clinical benefit rate of this regimen in these patients.
4. Determine the safety profile of this regimen in these patients.

Entry Criteria

Disease Characteristics:

• Histologically confirmed breast cancer
  • Metastatic disease
    • Patients with only bone metastases are not eligible
• Refractory disease, defined as disease progression, drug-related adverse reaction, or disease relapse during or within 12 months after completion of paclitaxel or docetaxel AND doxorubicin or epirubicin administered in the neoadjuvant, adjuvant, or metastatic setting
  • Total neoadjuvant or adjuvant taxane dose > 700 mg/m² for paclitaxel or > 240 mg/m² for docetaxel
  • Total taxane dose > 350 mg/m² for paclitaxel or > 120 mg/m² for docetaxel in the metastatic setting
  • Total neoadjuvant or adjuvant anthracycline dose > 240 mg/m² for doxorubicin or epirubicin
  • Total anthracycline dose > 120 mg/m² for doxorubicin or epirubicin in the metastatic setting
• HER2/neu overexpression
  • 3+ by immunohistochemistry or positive by fluorescence in situ hybridization
• No symptomatic brain metastases
• No pleural or pericardial effusion or ascites
• Hormone receptor status:
  • Not specified

Prior/Concurrent Therapy:

Biologic therapy

• At least 4 weeks since prior alkylating agents, carcinostatic antibiotics, or other carcinostatic agents

Endocrine therapy

• At least 4 weeks since prior goserelin or leuprolide for metastatic disease
• At least 2 weeks since prior oral endocrine agents for metastatic disease
• No concurrent endocrine therapy

Radiotherapy

Other

• Concurrent bisphosphonates for bone metastases allowed

Expected Enrollment

A total of 75 patients will be accrued for this study within 3 years.

Outcomes

Median survival and 2-year survival rate as measured by the Kaplan-Meier method 2 years after completion of study treatment

Progression-free survival
Response rate
Clinical benefit rate as measured by Kaplan-Meier method 2 years after completion of study treatment
Safety profile as measured by the Kaplan-Meier method 2 years after completion of study treatment

Outline

This is a multicenter study. Patients are stratified according to prior treatment with trastuzumab (Herceptin®) (yes vs no), HER2/neu status (3+ by immunohistochemistry vs positive by fluorescence in situ hybridization), and class of refractory disease (primary vs secondary vs treatment discontinuation due to adverse events).

Patients receive oral capecitabine once daily on days 1-21 and trastuzumab IV on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed for up to 2 years.
