Neoadjuvant Epirubicin, Cyclophosphamide, and Paclitaxel With or Without Gemcitabine in Treating Women Who Are Undergoing Surgery for Early Breast Cancer
A Phase 3 study testing cyclophosphamide, epirubicin hydrochloride and gemcitabine hydrochloride in people with Breast Cancer, run by Cambridge University Hospitals NHS Foundation Trust at 1 site in United Kingdom.
Trial summary
RATIONALE: Drugs used in chemotherapy, such as epirubicin, cyclophosphamide, paclitaxel, and gemcitabine use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. Read more about this study

About this study
Official title: A Phase III Randomized Neoadjuvant Study of Sequential Epirubicin/Cyclophosphamide and Paclitaxel + - Gemcitabine in Poor Risk Early Breast Cancer
RATIONALE: Drugs used in chemotherapy, such as epirubicin, cyclophosphamide, paclitaxel, and gemcitabine use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. It is not yet known which combination chemotherapy regimen is more effective in treating early breast cancer.
PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating women who are undergoing surgery for early invasive breast cancer.
Read the detailed description
OBJECTIVES:
Primary
- Compare the complete pathological response rate in women with poor-risk early breast cancer treated with neoadjuvant sequential epirubicin, cyclophosphamide, and paclitaxel with vs without gemcitabine.
Secondary
- Compare the disease-free and overall survival of patients treated with these regimens.
- Compare the toxicity of these regimens in these patients.
- Compare the effect of these regimens on prognostic factors in these patients.
- Correlate molecular profiles, specific gene mutations, and genomic and gene expression changes with clinical outcome in these patients.
- Compare the quality of life of patients treated with these regimens.
- Determine the health economics associated with this study.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to estrogen-receptor status (negative vs greater than 10% positive cells), HER-2 status (positive vs negative), tumor size (30-50 mm vs greater than 50 mm), and clinical involvement of axillary nodes (yes vs no). Patients are randomized to 1 of 4 treatment arms.
- Neoadjuvant sequential chemotherapy:
- Arm I: Patients receive epirubicin IV and cyclophosphamide IV on day 1. Treatment repeats every 21 days for 4 courses. Patients then receive paclitaxel IV over 3 hours on day 1. Treatment repeats every 21 days for 4 courses.
- Arm II: Patients receive paclitaxel as in arm I followed by epirubicin and cyclophosphamide as in arm I.
- Arm III: Patients receive epirubicin and cyclophosphamide as in arm I followed by paclitaxel as in arm I and gemcitabine IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for 4 courses.
- Arm IV: Patients receive paclitaxel as in arm I and gemcitabine as in arm III followed by epirubicin and cyclophosphamide as in arm I.
- Surgery: After completion of neoadjuvant chemotherapy, patients in all arms undergo definitive surgery.
Tumor tissue is removed from a subset of patients during serial biopsies. Molecular and genetic profiling, mutation analysis, and comparative genomic analysis is performed on the tissue samples.
Quality of life is assessed at baseline, after 4 courses of chemotherapy, after the completion of chemotherapy, after surgery, and then every 6 months for 2 years.
Patients are followed every 2 months for 2 years and then every 3 months for 3 years.

PROJECTED ACCRUAL: A total of 800 patients (200 per treatment arm) will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing cyclophosphamide, epirubicin hydrochloride and gemcitabine hydrochloride in people with Breast Cancer, run by Cambridge University Hospitals NHS Foundation Trust at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 7 Aug 2013. 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 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?
Results are not available in the source record.
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?
Complete pathological response after 4 courses. 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 NCT00070278, which also lists 3 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.
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 Aug 2013.
