简要总结
The purpose of this study is to compare the Time To Disease Progression (TTDP) between those patients with unresectable, locally recurrent or metastatic breast cancer who are treated with concomitant Docetaxel plus Gemcitabine to those patients treated with sequential therapy of Docetaxel followed by Gemcitabine.
详细描述
This is an open, multicenter, two-armed Phase III study
Patients will be randomized to either of the following two arms:
Arm A (concomitant arm), Gemcitabine 1000 mglm2 will be administered intravenously on Days 1 and 8, repeated on Day 22. Docetaxel 75 mg/m2 will be given on Day 8 (before Gemcitabine), repeated on Day 22. This 3-week schedule defines a cycle of treatment for this arm. Overall 8 cycles will be administered.
Arm B (sequential arm) four cycles of Docetaxel 100 mg/m2 an Day 1, repeated an Day 22, followed by four cycles of Gemcitabine 1250 mg/m2 an a Day 1 and 8, repeated an Day 22, will be given. Both drugs will be administered in a 3-week schedule.
Bimonthly follow-up for patients without confirmed disease progression until progression of disease. Long-term follow-up for patients with confirmed disease progression will be done in 4 intervals.
