About this study
Official title: A Phase II, Randomised, Double-Blind, Placebocontrolled Study To Investigate The Effects Of ZD1839 (IRESSA™) On Cell Proliferation In Oestrogen And Progesterone Receptor Negative Breast Cancer Prior To Surgery
This is a Phase II, randomised, double-blind, placebo-controlled study. Subjects with histologically-confirmed oestrogen receptor negative (ER-), progesterone receptor negative (PgR-) primary breast cancer breast cancer will be randomly assigned in a 2:1 ratio to receive ZD1839 250 mg once daily or matching placebo for a total period of 5 weeks. Surgical intervention will take place after 4 weeks (on Day 29) and treatment will continue for 1 week after surgery.

What is being measured
The primary outcome is the main question the study is designed to answer.
Estimate the effect of ZD1839 compared with placebo on the change in tumour cell proliferation in patients who have completely ER negative & PgR negative breast cancer
Aassessment of biomarker Ki-67 in breast cancer tissue at baseline by core biopsy and after 4 weeks on the surgical specimen
Secondary outcomes (5)
To assess the effect of 4 weeks of ZD1839 on the change in tumour size as assessed by ultrasounds.
To correlate the expression of tissue biomarkers (HER family and epidermal growth factor [EGF] related pathways) in the baseline biopsy sample and in the surgical (endpoint) specimen with the anti-proliferative effect of ZD1839.
To determine the effect of ZD1839 on HER-2 phosphorylation and other biomarkers in the surgical (endpoint) specimens when compared with the baseline biopsies
To assess the effect of ZD1839 on apoptosis as assessed by TUNEL in the surgical (endpoint) specimens when compared with the baseline biopsies
To determine plasma trough concentrations of ZD1839 and correlate these with molecular biomarkers detected in breast cancer tissue.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Gefitinib in people with Breast Cancer, run by AstraZeneca at 1 site in Italy.
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 3 inclusion and 2 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The record says: withdrawn, as of the sponsor's last update on 28 Jan 2011. 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 Italy. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 was withdrawn before enrolling participants, so there are no results.
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?
Estimate the effect of ZD1839 compared with placebo on the change in tumour cell proliferation in patients who have completely ER negative & PgR negative breast cancer. The study lists 2 primary outcomes in all. 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 28 Jan 2011.
