Everolimus in Treating Patients WIth Recurrent or Metastatic Breast Cancer

This study has been completed.
Information provided by:
Canadian Cancer Trials Group Identifier:
First received: November 18, 2005
Last updated: November 25, 2016
Last verified: January 2011

RATIONALE: Everolimus may stop the growth of tumor cells by blocking blood flow to the tumor.

PURPOSE: This randomized phase II trial is studying two different schedules of everolimus to see how well they work in treating patients with recurrent or metastatic breast cancer.

Condition Intervention Phase
Breast Cancer Drug: everolimus Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Randomized Phase II Study of Two Different Schedules of RAD001C in Patients With Recurrent/Metastatic Breast Cancer

Primary Outcome Measures:
  • Response rate by clinical evaluation every 4 weeks and radiologic reevaluation every 8 weeks
  • Early progression rate by clinical evaluation every 4 weeks and radiologic reevaluation every 8 weeks

Secondary Outcome Measures:
  • Adverse event rates
  • Time to progression by clinical evaluation every 4 weeks and radiologic reevaluation every 8 weeks
  • Response duration by evaluation 4 weeks after response and then every 8 weeks
  • Correlative assessment of response with molecular markers of mTor activity on archival tissue
  • Optional correlative assessment of response with molecular markers of mTor activity on fresh tissue

Study Start Date: January 2005
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Detailed Description:



  • Determine the efficacy of 2 different treatment schedules of everolimus, in terms of clinical/radiological response and early progression, in patients with recurrent or metastatic breast cancer.


  • Determine the time to progression and response duration in patients treated with these regimens.
  • Determine the toxic effects of these regimens in these patients.
  • Correlate molecular markers of mTOR activity in tumor tissue with objective tumor response in patients treated with these regimens.

OUTLINE: This is a randomized, open label, multicenter study. Patients are stratified according to presence of visceral metastases (yes vs no) and prior chemotherapy regimens for recurrent disease (0 vs 1). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral everolimus once daily on days 1-28.
  • Arm II: Patients receive oral everolimus 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 at 4 weeks and then periodically until disease progression.

PROJECTED ACCRUAL: A total of 60 patients (30 per treatment arm) will be accrued for this study.
