Appeals Court Rules Against Amgen in Neupogen Biosimilar Case
Continuing the Amgen-Sandoz debate over provisions of the Biologics Price Competition and Innovation Act (BPCIA), the Federal Circuit Court of Appeals has ruled that state claims against Sandoz sought by Amgen are preempted by federal law. The appeals court heard the case on remand from the Supreme Court, which held on cross-appeals from the two companies that an injunction under federal law is not available to force a biosimilar applicant to disclose its aBLA to the reference product sponsor. The high court also ruled that biosimilar applicants may provide required notice of commercial marketing to the reference product sponsor either before or after FDA licenses its biosimilar.
The appeals court said it agrees with Sandoz that the BPCIA preempts state law claims predicated on an applicant’s failure to comply with the provision dealing with disclosure of its aBLA. It noted that patents are inherently a federal matter and that FDA has exclusive authority to license biosimilars. It also found that Amgen was trying to use California law to impose penalties on Sandoz that are not provided in the BPCIA.
“The preemption analysis here demonstrates that Amgen’s state law claims conflict with the BPCIA and intrude upon a field, biosimilar patent litigation, that Congress reserved for the federal government,” the appeals court concluded.
