Bevacizumab's Wild Ride For Metastatic Breast Cancer

First, we run through 4 recent FDA-approved expanded indications for HCC, small cell lung cancer, MDS-related anemia, and BRAF-v600e-mutated colorectal cancer. Then, we review the evidence that warranted bevacizumab's FDA-approval for metastatic breast cancer way back in 2008 (E2100) and its subsequent labeled indication removal by the FDA (Avado & Ribbon-1). Why talk about old news? Perhaps there's a lesson here as we consider using untested drugs...
