Bevacizumab plus paclitaxel versus placebo plus paclitaxel as first-line therapy for HER2-negative metastatic breast cancer (MERiDiAN): A double-blind placebo-controlled randomised phase III trial with prospective biomarker evaluation
This is the first prospective evaluation of a candidate biomarker for bevacizumab. Adding bevacizumab to paclitaxel significantly improved progression-free survival (primary end-point). Results do not support plasma vascular endothelial growth factor-A as a predictive biomarker for bevacizumab.
