Clinical Trial Summary

Bevacizumab plus chemotherapy improves response rates and prolongs PFS when used as first- and second-line therapy for advanced breast cancer. However, bevacizumab has not improved OS in the individual studies currently reported. In Europe, EMA has maintained its indication associated with weekly paclitaxel in first line metastatic breast cancer and more recently with capecitabine based on RIBBON 1 trial's results.

The identification of patient subsets that receive the most clinical benefit would enable more specific treatment administration of bevacizumab and allow patients unlikely to benefit the opportunity to seek other treatment modalities. Unfortunately, despite efforts to identify patient subsets with a differential benefit from bevacizumab, no validated biomarkers have been defined.

The Avastin cohort is a unique opportunity to investigate various biological and imaging parameters which could be related to clinical benefit of the combination of bevacizumab and weekly paclitaxel in first line metastatic breast cancer in a homogeneously treated population in French cancer centers. This trial will gather the expertise of several translational research platforms of different cancer centers from the UNICANCER consortium.
