Summary
Taxanes (such as paclitaxel) are highly active to treat breast cancer. Abraxane® (nanoparticle albumin-bound paclitaxel) compared to standard paclitaxel improves efficacy and tolerability. When combined with a taxane, platinum agents improve response in metastatic breast cancer, with carboplatin conferring less toxicity than cisplatin. Monoclonal antibodies including bevacizumab target vascular endothelial growth factor (VEGF) to reduce angiogenesis. We hypothesize that the previously-untested combination of weekly Abraxane® and carboplatin plus biweekly bevacizumab will lengthen time to progression without producing intolerable toxicity.
