Introduction
The litigation between Biogen Inc. and Sandoz Inc., along with Polpharma Biologics S.A., is a significant case in the biosimilars landscape, particularly under the Biologics Price Competition and Innovation Act (BPCIA). Here, we delve into the key aspects of this litigation, including the background, legal arguments, and the current status of the case.
Background of the Case
Biogen Inc. filed a complaint against Sandoz Inc. and Polpharma Biologics S.A. on September 9, 2022, in the District of Delaware. This lawsuit revolves around the alleged infringement of Biogen’s patents related to its biologic product, Tysabri® (natalizumab), which is used to treat autoimmune diseases such as multiple sclerosis and Crohn's disease[2][3][5].
Patents in Dispute
Biogen initially asserted infringement of 28 patents, which include methods of treatment with natalizumab, methods of manufacturing antibody products like natalizumab, and a companion assay used to reduce the risk of serious side effects in natalizumab patients. However, in the first amended complaint filed on December 1, 2022, the number of asserted patents was reduced to 17[3].
Motion for Preliminary Injunction
On January 20, 2023, Biogen filed a motion for a preliminary injunction to prevent Sandoz and Polpharma from commercially importing, marketing, and selling their natalizumab biosimilar, Tyruko®, until the patent infringement claims were fully adjudicated. This motion was based on four of the 17 asserted patents[3].
Court Ruling on Preliminary Injunction
After oral arguments, the court denied Biogen’s motion for a preliminary injunction. The court found that Biogen failed to prove it would suffer irreparable harm and a likelihood of success on the merits. Specifically, the court determined that Biogen’s alleged harms of price erosion, lost sales and market share, and reputational harm were "speculative and uncertain" and lacked a causal nexus between the alleged infringement and the harm. Additionally, the court found that Biogen failed to show that the defendants would infringe any of the four patents at issue[3].
Current Status of the Case
The case is currently in the discovery phase, with several discovery disputes being resolved by the court. The claim construction process is ongoing, with a joint technology tutorial and claim construction hearing scheduled for May 17 and 29, 2024, respectively. A five-day trial is set to begin on May 5, 2025[3].
Significance of the Case
This litigation is significant for several reasons:
- First BPCIA Litigation Involving Biogen: It is the first BPCIA litigation where Biogen is the reference product sponsor.
- First BPCIA Litigation Involving Polpharma: It marks the first BPCIA litigation involving Polpharma Biologics S.A.
- First Proposed Biosimilar of Tysabri: It is the first case involving a proposed biosimilar of Tysabri®, a groundbreaking biologic product[3].
Implications for the Biosimilars Market
The outcome of this case will have important implications for the biosimilars market. Biosimilars are crucial for reducing healthcare costs and increasing patient access to biologic therapies. The litigation highlights the complexities and challenges involved in navigating the intellectual property landscape for biosimilars.
