Per reporting in BioCentury, in the first lawsuit filed by an originator company over a biosimilars application, Amgen alleged that Sandoz has unlawfully refused to follow the patent resolution protocol laid out by the Biologics Price Competition and Innovation Act of 2009 (BPCIA).
The suit, filed in the U.S. District Court for the Northern District of California, concerns Sandoz's application to market a biosimilar version of Amgen's Neupogen filgrastim G-CSF, a recombinant methionyl human granulocyte colony-stimulating factor. Under BPCIA, Sandoz was required to provide Amgen with its BLA and manufacturing information for the biosimilar within 20 days of FDA’s decision to accept the application for review.
According to Amgen, Sandoz failed to disclose this information, thus depriving Amgen of the opportunity to assess potential patent infringement claims and potentially seek an injunction to prevent Sandoz from commercializing its biosimilar candidate. Amgen is seeking restitution for unfair competition and an injunction to prevent Sandoz from commercializing the biosimilar filgrastim until Amgen is "restored to the position it would have been [in] had Defendents met their obligations under the BPCIA."
Amgen is also seeking an injunction to prevent Sandoz from advancing through FDA's approval process until the company has obtained permission from Amgen to use the filgrastim license. Additionally, Amgen is seeking a judgment of patent infringement for U.S. patent No. 6,162,427. The suit also demands a jury trial.
