Doctors scour drug supplies after fake Avastin found
A U.S. distributor of phony vials of the widely-used cancer drug Avastin aroused suspicion at doctor's offices as early as July, well before health regulators issued their own warning and sparked new alarm over counterfeit medicines.
The U.S. Food and Drug Administration said this week it notified 19 oncology practices they had purchased drugs from a supplier not approved by the agency, including a counterfeit version of Roche Holding AG's, Avastin, that did not contain the multibillion-dollar drug's active ingredient, bevacizumab.
The FDA and Roche's Genentech division said on Wednesday they were still investigating how widely the fake medicine was distributed. They do not know how many patients might have been affected, or if anyone was harmed.
Connie Jung of the FDA's Office of Drug Security said it was possible more practices could be involved.
