Introduction
Amgen Inc. has been involved in a series of litigation cases related to its biologic products, particularly focusing on the denosumab biosimilars. One of the recent and significant cases is Amgen Inc. v. Accord Healthcare, Inc., which involves a Biologics Price Competition and Innovation Act (BPCIA) complaint. Here is a detailed summary and analysis of this litigation.
Background of the Litigation
On November 13, 2024, Amgen filed a BPCIA complaint in the District Court for the Eastern District of North Carolina against Accord Biopharma, Inc., Accord Healthcare, Inc., and Intas Pharmaceuticals, Ltd. This complaint is related to Accord’s proposed biosimilar of Amgen’s PROLIA and XGEVA, which contain the active ingredient denosumab[1].
Patent Assertions
In this litigation, Amgen has asserted 33 patents that allegedly cover the denosumab antibody, pharmaceutical compositions comprising denosumab, innovative methods of manufacturing therapeutic proteins like denosumab, and denosumab products. These patents are crucial for Amgen’s claim of infringement by Accord’s biosimilar products[1].
BPCIA Requirements and Compliance
Amgen alleges that Accord did not fully comply with the requirements set out in section 262(l)(2)(A) of the BPCIA. Specifically, Amgen claims that Accord failed to provide sufficient information about the processes used to manufacture the biological product, despite initial disclosures and subsequent supplements to the document production. This lack of compliance is central to Amgen’s argument that Accord has not met the necessary legal standards for biosimilar approval[1].
Infringement Claims and Relief Sought
Amgen seeks several forms of relief, including:
- A judgment that Accord has infringed, either literally or under the doctrine of equivalents, one or more claims of each of the patents-in-suit.
- A permanent injunction against the commercial manufacture, use, offer to sell, and sale within the United States, and importation into the United States, of Accord’s denosumab biosimilar products before the expiration of each of the patents-in-suit.
- A judgment that Accord has infringed or will infringe one or more claims of each of the patents-in-suit by making, using, offering for sale, or selling within the United States, or importing into the United States, one or more of Accord’s denosumab biosimilar products during the term of the patents-in-suit.
- A permanent injunction against future infringement by Accord and its affiliates.
- Damages and a declaration that the case is exceptional, along with an award of attorneys’ fees[1].
Context of Previous Litigations
This case is part of a broader series of BPCIA litigations involving denosumab biosimilars. Amgen has previously litigated against other companies such as Sandoz, Celltrion, Samsung Bioepis/Samsung Biologics, and Fresenius. These cases highlight the ongoing legal battles in the biopharmaceutical industry to protect intellectual property and market exclusivity[1].
Legal Implications and Precedents
The outcome of this case will be significant for the biopharmaceutical industry, particularly in the context of BPCIA litigation. The court’s decision on the validity of Amgen’s patents and Accord’s compliance with BPCIA requirements will set important precedents for future biosimilar approvals and patent disputes.
Industry Impact
The litigation between Amgen and Accord reflects the broader challenges faced by biologic manufacturers in protecting their intellectual property while navigating the complex regulatory landscape of biosimilars. The case underscores the importance of thorough compliance with BPCIA requirements and the vigorous defense of patents to maintain market exclusivity.
