The Food and Drug Administration has tracked counterfeit bevacizumab, the cancer drug marketed as Avastin, to at least one foreign supplier and identified 19 medical practices in the United States that purchased unapproved cancer medicines, possibly including counterfeit bevacizumab.

The FDA said the practices obtained the fake Avastin from Quality Specialty Products (QSP), a foreign supplier also known as Montana Health Care Solutions. QSP products are also distributed by Volunteer Distribution in Gainesboro, Tenn., the agency said.

Courtesy of Genentech This package of counterfeit Avastin has the letter B in the lot number and a date of manufacture -- neither of which appears on packages of Avastin approved for use in the United States. Also, Genentech is not identified on the label, and the expiry date is written entirely in numerals.

The FDA has requested that medical practices stop using any remaining products purchased from these suppliers "or any other unapproved foreign source," because the agency cannot ensure the safety or efficacy of any of these unapproved products.

"The Agency is very concerned that these products may cause harm to patients because they are unsafe or ineffective. ... These products may be from unknown sources; have unknown ingredients; and may not have been manufactured, transported or stored under proper conditions required by U.S. law, regulations, and standards," the agency said.

Avastin’s manufacturers announced Feb. 14 that they learned of the distribution of the counterfeit in the United States. "The counterfeit product is not safe or effective and should not be used. Chemical analyses of the counterfeit vials tested to date have confirmed the product does not contain the active ingredients for Avastin," warned F. Hoffmann-La Roche and Genentech.

Avastin, an injectable medicine used to treat many cancers, is administered to patients in clinics, hospitals, and doctors’ offices. The counterfeit version does not contain the monoclonal antibody bevacizumab.

The FDA similarly warned health care professionals and patients about a counterfeit version of Avastin 400mg/16mL, which may have been purchased and used by some medical practices in the United States.

The FDA has since issued letters to 19 U.S. medical practices that purchased unapproved cancer medicines that may include the counterfeit Avastin. It is believed that some product in the United States labeled as Avastin 400 mg/16 mL with the following lot numbers on either the vials or packaging may be counterfeit: B86017, B6011, and B6010.

Importantly, the counterfeit product does not look like authentic Avastin. Authentic Avastin’s cartons and vials (approved for use in the United States) have "Genentech" or "Genentech, a member of the Roche Group" printed on the labels. The counterfeit version is labeled as Avastin, manufactured by Roche, which manufactures Avastin for marketing outside of the United States.

In addition, the lot number on the carton and vial should be six digits with no letters; the expiry date is formatted as a three-letter month and four-digit year (such as, JUL 2014); the date of manufacture is not printed on the carton or vial; and all the text on the vial labels, cartons, and package inserts is in English on products approved for sale in the United States.
