7 Healthcast: Hearing may be end for breast cancer drug

The two-day Food and Drug Administration meeting is unprecedented since the agency has already ruled against the drug, saying it neither extends nor improves life for breast cancer patients. Roche has taken the rare step of challenging government regulators.

Roche says it needs more time to study which patients respond to Avastin. But that argument may fall on deaf ears: Five out of six FDA panelists have already voted against the drug. The ultimate decision will be made by FDA Commissioner Margaret Hamburg.
