Study Prompts Calls for ‘Black Box’ Warning for Cancer Drug
A new study found that Avastin, a drug designed to treat cancer, increases patients' risk of developing serious blood clots. The study's authors say Avastin should receive a "black box" warning, FDA's strongest warning. However, a spokesperson for drugmaker Genentech argues that Avastin's label already includes a warning about blood clot risk.
