Counterfeit Avastin hits U.S. shores, Genentech warns

Counterfeit Avastin — the world’s best-selling cancer drug — is being distributed in the United States, Genentech Inc. and parent company Roche warned Tuesday.
Officials from South San Francisco-based Genentech could not say if patients had been directly harmed by counterfeit Avastin, which has been sold at least since December, or how much revenue the company had lost. But a Roche evaluation of the counterfeit vials showed that they did not contain the active ingredient in Avastin.
