Letrozole in Metastatic Breast Cancer in Combination With Chemotherapy
A Phase 2/3 study testing Letrozole in people with Metastatic Breast Cancer, run by Novartis at 1 site in Germany.
Trial summary
Therapeutic interventions for patients with metastatic breast cancer are aimed at prolonging survival and improving the quality of life. The objective of this trial is to assess if an initial chemotherapy followed by an endocrine therapy leads to a longer disease-free interval as compared to chemotherapy alone.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Letrozole in people with Metastatic Breast Cancer, run by Novartis at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Nov 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective response rate (complete remission, partial remission,no change, progressive disease) by clinical palpation and radiologic imaging every 3 months until disease progression. It is what the study was designed to measure, not a finding.
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 19 Nov 2009; AzTrials last refreshed its copy on 8 Nov 2026.
