To compare the anti-tumour effects as measured by changes in various biomarkers, of a combination of Faslodex and Arimidex with Faslodex alone and Arimidex alone in postmenopausal women patients with primary breast cancer who are awaiting curative-intent surgery.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage Change From Baseline to Time of Surgery in Oestrogen Receptor (ER) H-score: Antitumour Effects of Fulvestrant, Anastrozole and a Combination of Both as Measured by the ER H-score.
Time Frame: Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)
For each sample, the ER H-score is calculated from the percentage of cells staining very weak (+/-); weak (+); moderate (++); or strong (+++) as follows: H-score = [(0.5 x percent +/-) + (1 x percent +) + (2 x percent ++) + (3 x percent +++)]. Range 0-300. The greater the change from baseline (randomization) in ER H-score, the greater the blockage of ER expression and the greater the potential anti-tumour activity. Percentage change from baseline=[(SRG - BL)/BL]x100
Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)
Percentage Change From Baseline to Time of Surgery in Progesterone Receptor (PgR) H-score: Antitumour Effects of Fulvestrant, Anastrozole and a Combination of Both as Measured by the PgR H-score.
Time Frame: Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)
For each sample, the PgR H-score is calculated from the percentage of cells staining very weak (+/-); weak (+); moderate (++); or strong (+++) as follows: H-score = [(0.5 x percent+/-) + (1 x percent+) + (2 x percent++) + (3 x percent+++)]. Range 0-300. The greater the change from baseline (randomization in PgR H-score, the greater the blockage of PgR expression and the greater the potential anti-tumour activity. Percentage change from baseline=[(SRG - BL)/BL]x100
Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)
Percentage Change From Baseline to Time of Surgery in Ki67 Labelling Index: Antitumour Effects of Fulvestrant, Anastrozole and a Combination of Both as Measured by the Ki67 Labelling Index.
Time Frame: Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)
For each sample, the Ki67 labelling index is calculated as the percentage of cells stained positive for Ki67. Range 0-100. The greater the change from baseline (randomization) in Ki67 labelling index, the greater the blockage of Ki67 expression and the greater the potential anti-tumour activity. Percentage change from baseline=[(SRG - BL)/BL]x100
Surgery (SRG) was to be performed between days 15 and 22 after baseline (BL)

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
