Who cannot join

  • Multifocal disease (cancer that starts in several different sites)
  • Patients with bilateral breast tumours.
  • Patients who are eligible for breast conserving surgery.
  • Evidence of inflammatory breast cancer or distant metastasis.
  • Simultaneous anti-cancer treatments such as chemotherapy, immunotherapy/biological response modifiers, endocrine therapy (including steroids), bisphosphonate therapy and radiotherapy.

  • The following additional treatments are NOT allowed during the treatment phase of the study:
Show all 13Show fewer
  • Any other anti-cancer therapy
  • Hormone replacement therapy.
  • Estrogen cream (including any intra-vaginal preparation).

Secondary outcomes (4)
  1. Reduction in tumour volume every 2 months throughout the study

    Measured: 12 months

  2. Response rate in line with the Response Evaluation Criteria in Solid Tumors criteria

    Measured: 12 months

  3. Long term (5-year) local recurrence rate

    Measured: 5 years

  4. Safety and tolerability of the treatment prior to surgery

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing letrozole in people with Breast Cancer, run by Novartis Pharmaceuticals at 20 sites in United Kingdom.

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 17 inclusion and 13 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 7 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United Kingdom. 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 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?

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?

Optimum length of treatment with letrozole (2.5 mg daily) preoperatively, on tumour measured by clinical examination and breast ultrasound (time frame: 12 months). 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 NCT00330317, which also lists 1 linked publication.

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 7 Feb 2017.
