In Amgen v. Apotex, the Federal Circuit rejected Apotex’s arguments that the 180-day pre-marketing notice requirement does not apply to biosimilar applicants who participated in the “patent dance” process of the Biologics Price Competition and Innovation Act (“BPCIA”), expanding on its decision in Amgen v. Sandoz that 42 USC § 262(l)(8)(A) is a mandatory, stand-alone requirement. The Supreme Court has asked the Solicitor General to weigh in on whether it should grant certiorari in Amgen v. Sandoz. Will this decision make the Court more or less likely to review the Federal Circuit’s interpretation of this important biosimilar statute?
The biologic product at issue is Amgen’s Neulasta® (pegfilgrastim) product. Amgen describes pegfilgrastim as “a recombinantly expressed, 175-amino acid form of … human granulocyte-colony stimulating factor (‘G-CSF’) conjugated to a 20 kD monomethoxypolyethylene glycol (m-PEG) at the N-terminus.” After Apotex filed a Biologic License Application (BLA) seeking FDA approval to market a biosimilar version of Neulasta® (pegfilgrastim), the parties followed several steps of the patent dance procedures, which resulted in Amgen asserting U.S. Patent Nos. 8,952,138 and 5,824,784 in the U.S. District Court for the Southern District of Florida. Those infringement claims are being litigated, although the ‘784 patent has been dropped since it expired.
As noted in the Federal Circuit decision, Apotex sent Amgen a letter on April 17, 2015, stating that it was “providing notice of future commercial marketing pursuant to 21 USC § 262(l)(8)(A), though Apotex lacked (as it still lacks) an FDA license.” Amgen sought a preliminary injunction to “require Apotex to provide … notice if and when it receives a license and to delay any commercial marketing for 180 days from that notice.” The district court granted that motion, citing the Federal Circuit decision in Amgen v. Sandoz that notice cannot be given before the biosimilar product is approved. Apotex appealed.
The [§ 262(l)](8)(A) requirement of 180 days’ post-licensure notice before commercial marketing … is a mandatory one enforceable by injunction whether or not [the biosimilar applicant provided a copy of its biosimilar application to the reference product sponsor in accordance with § 262(l)(2)(A)].
The court also considered and rejected Apotex’s arguments based on the relationship between § 262(l)(8)(A) and other sections of the BPCIA, such as § 262(l)(9)(B) and § 262(l)(9)(C), which give the reference product sponsor the right to bring delcaratory judgment actions when the biosimilar applicant fails to follow some or all of the patent dance procedures.
Perhaps Apotex’s most compelling argument was that the court’s interpretation of 262(l)(8)(A) effectively gives original biologic products 12.5 years of exclusivity rather than the 12 years provided by Congress in § 262(k)(7). The court dealt with this argument in two ways. First, the court noted that “§ 262(k)(7) by its terms establishes the 12-year date only as an earliest date, not a latest date, on which a biosimilar license can take effect” (emphasis added). Second the court hypothesized that the FDA could implement the 12-year exclusivity period by “issu[ing] a license before the 11.5-year mark and deem[ing] the license to take effect on the 12-year date.” In that case, the 180-days notice could be given in time to expire when the 12-year exclusivity period expires.
