About this study

Official title: Randomized Comparison of a Preoperative, Dose-Intensified, Interval-Shortened, Sequential Chemotherapy With Epirubicin, Paclitaxel and CMF ± Darbepoetin Alfa Versus a Preoperative, Sequential Chemotherapy With Epirubicin and Cyclophosphamide Followed by Paclitaxel in Standard Dosage ± Darbepoetin Alfa in Patients With Primary Breast Cancer

The present clinical trial will investigate the efficacy of a sequential interval-shortened and dose-intensified preoperative use of epirubicin, paclitaxel and CMF with preoperative sequential administration of epirubicin and cyclophosphamide followed by paclitaxel in breast cancer. In addition, the influence of darbepoetin alfa on the response rate and quality of life is to be investigated in both treatment arms.

Read the detailed description

Arm A: Sequential treatment in standard doses with Epirubicin (90 mg/m2)/cyclophosphamide (600 mg/m2) d1, q21d - 4× followed by paclitaxel (175 mg/m2) d1, q21d - 4×.

Pegfilgratim should be used as secondary preventive after febrile neutropenia in the standard arm of the study, or in exceptional cases also after severe febrile neutropenia necessitating postponement of the treatment by more than one week ± Darbepoetin alfa 1 × 4.5 µg/kg of body weight every two weeks with the start of the first epirubicin dose (day 1) until 14 days after the last dose of paclitaxel Daily oral intake of 200 mg iron unless there complications occur with taking iron

Arm B: sequential dose-intensified, interval-shortened treatment with Epirubicin (150 mg/m2) d1, q14d - 3× followed by paclitaxel (225 mg/m2) d1, q14d - 3×, followed by CMF (600/40/600 mg/m2) d1/d8, q28d - 3× Obligatory pegfilgratim 6 mg after epirubicin and/or paclitaxel: subcutaneous injection on day 2. After CMF pegfilgrastim should be used as a secondary preventive measure

± Darbepoetin alfa 1 × 4.5 µg/kg of body weight every two weeks with the start of the first dose of epirubicin (day 1) until 14 days after the last dose of CMF Daily oral dose of 200 mg iron unless complications occur in taking iron.

Primary goal: Determining the relapse-free survival time and overall survival after dose-intensified sequential preoperative chemotherapy including anthracycline and taxan and/or after preoperative chemotherapy including anthracycline followed by taxan in a standard dose

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Epirubicin, paclitaxel, cyclophosphamide, Methotrexate, 5 FU, darbepoetin alfa and Epirubicin, Cyclophosphamide, Paclitaxel, dabepoetin alfa in people with Breast Cancer, run by GBG Forschungs GmbH.

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 9 inclusion and 12 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 15 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Relapse-free survival time and overall survival (time frame: 2007). 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 NCT00544232, 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 15 Feb 2016.
