Can FDA Implement The BPCIA As The CAFC Suggested?

In Amgen v. Apotex, the Federal Circuit held that under the Biologics Price Competition and Innovation Act (“BPCIA”), “an applicant must provide a reference product sponsor with 180 days’ post-licensure notice before commercial marketing begins.” The court dismissed concerns that its holding would extend the originator’s 12-year exclusivity period by 6 months, reasoning that the FDA could signal approval … Continue reading this entry

The PRICED Act Would Expedite Biosimilar Market Entry

Although the 12-year exclusivity period for original biologic products was a heavily negotiated provision of the Biologics Price Competition and Innovation Act (BPCIA), increased spending on biologic drugs has led to calls to shorten that exclusivity period to expedite biosimilar market entry. Most recently, on June 23, 2016, Illinois Congresswoman Jan Schakowsky and Senators John McCain (R-AZ) and Sherrod … Continue reading this entry

In Amgen v. Sandoz, a divided panel of the Federal Circuit issued its first decision interpreting the Biologics Price Competition and Innovation Act (BPCIA), and did so in a manner that appears to favor biosimilar applicants over owners of original biologic products (“reference product sponsors”).
