Carcinoma, Invasive Ductal, Breast Clinical Trial
Official title:
A Randomized Phase III Study to Investigate the Efficacy and Safety of Docetaxel + Capecitabine vs. Vinorelbine + Capecitabine Followed by Capecitabine Alone as 1st Therapy on Locally Advanced and Metastatic Breast Cancer Patients.
It is a phase III trial to explore the efficacy and safety of vinorelbine plus capecitabine (NX) and docetaxel plus capecitabine (TX) as first line treatment followed by capecitabine alone till Progressive Disease(PD). We plan to enroll 200 pts for limited budget and the non-inferior trend of the two curves is anticipated.
We designed the randomized non-inferiority study. Main Inclusion& exclusion Criteria include: 1) Histologically or cytologically confirmed breast cancer with unresectable locally advanced and/or metastatic disease; 2) Untreated patients with unresectable locally advanced and/or metastatic disease; 3) with at least 1 lesion measurable by radiological method(RECIST criteria); 4) Karnofsky Performance Status(KPS)≥70; 5) normal Adequate hepatic, renal, and bone marrow function; 6) Life expectancy of at least 12 weeks; 7) No previous chemotherapy for metastatic breast cancer. Primary endpoint is Progression free survival(PFS), second endpoint are safety profiles (National Cancer Institute-Common Toxicity Criteria 3.0, NCI-CTC 3.0), overall survival and response rate. During Primary study treatment, Arm A: Capecitabine: 1,000 mg/m2 per ora(PO) twice daily (day 1-14), Vinorelbine 25 mg/m2 intravenous(IV) over 3 hours on day 1 and 8, every 3 weeks, 21 days as one cycle and 6-8 cycles are required; Arm B: Capecitabine: 1,000 mg/m2 PO twice daily (day 1-14), Docetaxel 75 mg/m2 IV over 3 hours on day 1, every 3 weeks, 21 days as one cycle and 6-8 cycles are required. Patients who are responding (complete or partial), or whose disease is stable followed by Capecitabine: 1,000 mg/m2 PO twice daily (day 1-14) 21 days as one cycle until progression or unacceptable toxicity ;
