ICI 182780 in Treating Women With Metastatic Breast Cancer

This study has been completed.

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using ICI 182780 may fight breast cancer by blocking the activity of estrogen in the tumor cells.

PURPOSE: Phase II trial to study the effectiveness of ICI 182780 in treating patients who have metastatic breast cancer that has not responded to previous hormone therapy.

Condition Intervention Phase
Breast Cancer
Drug: fulvestrant
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Trial Of Fulvestrant (Faslodex) In Women With Metastatic Breast Cancer And Failure on Aromatase Inhibitor Therapy

Further study details as provided by Alliance for Clinical Trials in Oncology:

Primary Outcome Measures:
  • objective response rate [ Time Frame: Up to 10 years ]

Secondary Outcome Measures:
  • overall survival [ Time Frame: Up to 10 years ]
  • time to disease progression [ Time Frame: Up to 10 years ]

Enrollment: 80
Study Start Date: May 2001
Study Completion Date: August 2008
Primary Completion Date: March 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: fulvestrant

Patients receive fulvestrant intramuscularly on day 1. Courses repeat approximately every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 5 years or until disease progression. After disease progression, patients are followed every 3 months for 2 years and then every 6 months for 3 years.

Drug: fulvestrant

Detailed Description:


  • Determine the complete and partial objective response rate and duration of response in women with metastatic breast cancer who have failed aromatase inhibitor therapy treated with fulvestrant.
  • Determine the time to disease progression and overall survival of women treated with this drug.
  • Determine the toxicity of this drug in these women.

OUTLINE: Patients receive fulvestrant intramuscularly on day 1. Courses repeat approximately every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 5 years or until disease progression. After disease progression, patients are followed every 3 months for 2 years and then every 6 months for 3 years.
