简要总结
This is an open-label, single-arm, multi-center, Phase 2 study with Paclitaxel in combination with Bevacizumab in patients with Unresectable or Metastatic Angiosarcoma. The study aims to determine the safety and effectiveness of combining two drugs Paclitaxel and Bevacizumab in the treatment of Angiosarcoma that cannot be removed by surgery, or has spread to other parts of your body. The primary objective is to evaluate 4month non progression rate. The secondary objective is to evaluate overall response rate after 3rd and 6th cycle, median duration of response, 6th and 12th month survival, toxicity of Paclitaxel and Bevacizumab combination, toxicity of maintenance Bevacizumab and to collect paraffin-embedded tumor blocks for angiogenesis markers and tissue microarray.
详细描述
Regimen A versus B was chosen at the discretion of the treating physician. Both groups were analyzed together as far as outcome.
Patients were to receive paclitaxel 200 mg/m2 intravenously over 3 hours every 21 days (Regimen A) or pactlitaxel 90 mg/m2 weekly x 3 of a 28 day cycle (Regimen B) followed by bevacizumab 15 mg/kg intravenously over (cycle 1: 90 min; cycle 2: 60 min; cycles 3-6: 30 min) every 21 days x 6 cycles. Maintenance bevacizumab (MB) started after the completion of combination of paclitaxel and bevacizumab and it was given at a dose of 15 mg/kg intravenously once every 21 days for a maximum of 8 cycles. Patients were allowed to receive growth factors. Dose reductions were done based on hematologic and non-hematologic toxicities.

结局指标
主要结局
Progression-free Survival (PFS)
时间窗: 4 months
The primary objective of this study was to evaluate progression-free survival (PFS or non-progression rate) through 4 months from start of treatment. Progression is defined as ≥ 20% increase in the sum of the longest diameter of target lesions, as compared to the baseline measurements, and/or the appearance of one or more new lesion(s).
次要结局
- Overall Survival (OS) at 6 Months(6 months)
- Overall Survival (OS) at 12 Months(12 months)
- Overall Response Rate After 3 Cycles(12 weeks)
- Overall Response Rate After 6th Cycle(6 Cycles)
