What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the difference in event free survival and overall survival (subject to stand-alone or combined/meta-analysis) between postmenopausal women with HR +ve early BC who switched from tamoxifen to anastrozole and those who continued on tamoxifen.

Secondary outcomes (1)
  1. To assess the difference in event free survival & overall survival (subject to stand-alone or combined/meta-analysis) plus side effects between postmenopausal women with HR+ve early BC who switched from tam to anastrozole and those who continued on tam.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

What does the primary outcome measure?

To assess the difference in event free survival and overall survival (subject to stand-alone or combined/meta-analysis) between postmenopausal women with HR +ve early BC who switched from tamoxifen to anastrozole and those who continued on tamoxifen.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00291759, which also lists 2 linked publications.

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.
