About this study
Official title: Open Label, Multicenter Trial Of Femera (Letrozole) 2.5 mg As First-line Therapy In Postmenopausal Women With Metastatic Breast Cancer Relapsing Following Adjuvant Tamoxifen Therapy
RATIONALE: Estrogen can stimulate the growth of cancer cells. Letrozole may fight breast cancer by reducing the production of estrogen.
PURPOSE: Phase IV trial to study the effectiveness of letrozole in treating postmenopausal women who have metastatic breast cancer that has been previously treated with tamoxifen.
Read the detailed description
OBJECTIVES: I. Determine the time to progression of postmenopausal women with metastatic breast cancer treated with letrozole (Femara) as first-line therapy. II. Determine the objective response rate, time to treatment failure, survival rate, and changes in symptom distress in patients treated with this regimen.
OUTLINE: This is a multicenter study. Patients are stratified according to time to diagnosis of metastatic disease. Patients receive oral letrozole (Femara) daily. Treatment continues in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 590 patients will be accrued for this study.

What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2013.
