Capecitabine in Treating Patients With Metastatic Breast Cancer

Phase II Study of Fixed-Dose Capecitabine in Metastatic Breast Cancer

RATIONALE: Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase II trial is studying how well capecitabine works in treating patients with metastatic breast cancer.

Detailed Description

OBJECTIVES:

Primary

  • Determine the response rate in patients with metastatic breast cancer treated with a fixed-dose of capecitabine.

Secondary

  • Determine the clinical benefit, time to treatment failure (TTF), safety, and toxicity profile of this regimen in these patients.
  • Determine the pharmacokinetics (PK) and pharmacogenetics in these patients.
  • Correlate pharmacodynamic effects of this drug with toxicity and response in these patients.
  • Determine compliance and adherence to this regimen and correlate with PK parameters in these patients.

OUTLINE: This is an open-label study.

Patients receive a fixed-dose of oral capecitabine twice daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 45 patients will be accrued for this study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Capecitabine
26 patients received the pre-defined starting dose of capecitabine of 3,000 mg orally daily given in two divided doses. Two thirds of the patients received either the same dose or a 500 mg lower dose compared to what would have been administered with a commonly used body surface area (BSA)-dosing schedule (2,000 mg/m2 with rounding down to nearest 500 mg multiple).
A total of 115 cycles of therapy were administered and five patients did not complete cycle 1. The median number of cycles initiated was four (range 1-16).
