Preoperative Epirubicin Paclitaxel Aranesp Study (PREPARE)

GBG Forschungs GmbH720 enrolled

Overview

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.

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
