The pharmaceutical industry is no stranger to complex legal battles, and the In re Xyrem (Sodium Oxybate) Antitrust Litigation is a prime example of the intricate web of antitrust issues that can arise in this sector. This multidistrict litigation has captured the attention of legal experts, healthcare professionals, and industry observers alike, as it delves into allegations of anticompetitive practices surrounding the narcolepsy drug Xyrem.
Background of the Xyrem Antitrust Case
At the heart of this legal dispute is Xyrem, a medication used to treat narcolepsy, a chronic sleep disorder. Developed by Jazz Pharmaceuticals, Xyrem has been a significant revenue generator for the company. However, the drug's success has also led to scrutiny of Jazz's business practices, particularly its efforts to maintain market exclusivity.
The Rise of Xyrem
Xyrem, containing the active ingredient sodium oxybate, was approved by the FDA in 2002 for the treatment of cataplexy associated with narcolepsy. Jazz Pharmaceuticals acquired the rights to Xyrem in 2005 when it purchased Orphan Medical. Initially, the acquisition was not profitable, but Jazz's management team implemented a strategy to dramatically increase Xyrem's price, leveraging its unique position in the market.
As Jazz's co-founder and Chief Executive Officer ("CEO") Bruce Cozadd stated publicly, Jazz had "substantial pricing power" because "nothing else [ ] does what [Xyrem ] does. There is no substitute."[1]
This strategy proved highly successful, with Jazz's stock price growing approximately 5,000% from its 2009 low to its November 2010 price of over $50 per share.
The Antitrust Allegations
The core of the antitrust allegations against Jazz Pharmaceuticals and other defendants revolves around a series of actions allegedly taken to delay the entry of generic versions of Xyrem into the market. These actions include:
- Filing and enforcing patents
- Engaging in reverse payment settlements with potential generic competitors
- Abusing the FDA's Risk Evaluation and Mitigation Strategy (REMS) process
- Implementing a restricted distribution system
Plaintiffs argue that these actions collectively constituted an anticompetitive scheme designed to maintain Jazz's monopoly on sodium oxybate and keep prices artificially high.
Key Players in the Litigation
The Xyrem antitrust litigation involves multiple parties on both sides of the dispute.
Plaintiffs
The plaintiffs in this case can be broadly categorized into two groups:
-
Class Plaintiffs: A coalition of putative class representatives including:
- A.F. of L. – A.G.C. Building Trades Welfare Plan
- Blue Cross Blue Shield Association
- City of Providence, Rhode Island
- Government Employees Health Association, Inc.
- New York State Teamsters Council Health and Hospital Fund
- Self-Insured Schools of California
- UFCW Local 1500 Welfare Fund
- Xyrem patient Ruth Hollman
-
Individual Plaintiff: United HealthCare Services, Inc.
Defendants
The defendants in this case include:
- Jazz Pharmaceuticals Plc, Jazz Pharmaceuticals, Inc., and Jazz Pharmaceuticals Ireland Limited (collectively, "Jazz")
- Hikma Labs, Inc. (formerly known as Roxane Laboratories, Inc.), Hikma Pharmaceuticals USA Inc. (formerly known as West-Ward Pharmaceuticals Corp.), Eurohealth (USA), Inc., and Hikma Pharmaceuticals plc. (collectively, "Hikma")
- Amneal Pharmaceuticals LLC, Par Pharmaceuticals, Inc., and Lupin Ltd., Lupin Pharmaceuticals Inc., and Lupin, Inc. (collectively, the "Later Generic Defendants")
The Alleged Anticompetitive Scheme
The plaintiffs' allegations paint a picture of a multi-faceted strategy employed by Jazz to maintain its monopoly on Xyrem. Let's break down the key components of this alleged scheme.
Patent Strategies
Jazz filed for and obtained three families of patents related to Xyrem. Importantly, none of these patents claimed the active pharmaceutical compound (sodium oxybate) itself, as it had been discovered long ago. Instead, Jazz patented:
- Certain formulations and methods of treatment
- A drug distribution system
- Certain methods of administering sodium oxybate
These patents had expiration dates ranging from December 2019 to March 2033, potentially extending Jazz's market exclusivity well beyond the expiration of the original compound patent.
Abuse of the REMS Process
The Risk Evaluation and Mitigation Strategy (REMS) is an FDA-mandated program to ensure that the benefits of certain drugs outweigh their risks. Plaintiffs allege that Jazz abused this process to create barriers to generic entry.
According to Plaintiffs, Jazz's alleged abuse of the REMS process spanned nearly seven years beginning in late August 2008.[1]
Jazz allegedly took inconsistent and dilatory positions before the FDA regarding Xyrem's distribution restrictions. Initially advocating for a single-pharmacy distribution protocol, Jazz later proposed allowing multiple certified pharmacies, only to revert to a single-pharmacy model in 2011. This back-and-forth allegedly delayed the approval of a shared REMS that would have facilitated generic entry.
Reverse Payment Settlements
Perhaps the most controversial aspect of Jazz's alleged anticompetitive conduct was its series of reverse payment settlements with potential generic competitors. In these agreements, Jazz allegedly paid substantial sums to generic manufacturers in exchange for delaying their entry into the Xyrem market.
The value of these settlements was reportedly in the hundreds of millions of dollars for first-filer Hikma and tens of millions of dollars each for Later Generic Defendants Par, Lupin, and Amneal. These payments were structured in various ways, including:
- Licensing Hikma as the exclusive third-party marketer of an authorized generic version of Xyrem
- Providing acceleration clauses that would allow earlier entry if another generic entered the market
- Supplying Xyrem to the generic companies at favorable prices
Restricted Distribution System
Jazz implemented a patented distribution plan that operated through a single pharmacy, Express Scripts Specialty Distribution Services, Inc. This system was ostensibly part of the risk management strategy for Xyrem, given that its active ingredient (GHB) is known as a date-rape drug. However, plaintiffs allege that this system was designed to frustrate potential generic manufacturers' efforts to obtain approval for their products.
Legal Proceedings and Key Developments
The Xyrem antitrust litigation has been a complex and lengthy process, with several key developments shaping its course.
Consolidation into Multidistrict Litigation
On December 16, 2020, the United States Judicial Panel on Multidistrict Litigation consolidated the various lawsuits related to Xyrem into a multidistrict litigation in the United States District Court for the Northern District of California. This consolidation aimed to streamline the legal process and avoid duplicative discovery across multiple jurisdictions.
Motion to Dismiss
On August 13, 2021, Judge Lucy H. Koh issued an order granting in part and denying in part the defendants' motion to dismiss. This order allowed many of the plaintiffs' claims to proceed, setting the stage for further litigation.
Class Certification
On May 12, 2023, the Court certified two classes:
- A damages class of third-party payors in 31 states
- A nationwide injunctive relief class
This certification was a significant victory for the plaintiffs, allowing them to pursue their claims collectively.
Partial Settlement
In a notable development, the Court granted preliminary approval of a settlement with two defendants: Amneal and Lupin. The settlement includes:
- A $3.4 million settlement fund
- Release of all claims against Amneal and Lupin
- The settlement fund to be used to support continued litigation against the remaining defendants (Jazz and Hikma)
Economic Impact and Market Implications
The Xyrem antitrust litigation highlights the significant economic stakes in pharmaceutical patent disputes and the complex interplay between innovation, competition, and consumer welfare.
Price Increases and Profitability
Jazz's pricing strategy for Xyrem resulted in dramatic price increases. According to a Bloomberg report, the price of Xyrem increased by approximately 841% from 2007 through 2014. These price hikes translated into substantial profits for Jazz, with gross margins on Xyrem exceeding 90%.
Delayed Generic Entry
The alleged anticompetitive conduct has potentially delayed the entry of generic versions of Xyrem into the market. According to the plaintiffs, no AB-rated generics for Xyrem are currently on the market, and none will be available until at least December 31, 2025, if the allegations prove true.
Impact on Consumers and Insurers
The delayed entry of generic competition has significant implications for both consumers and insurers:
- Higher out-of-pocket costs for patients
- Increased spending for insurance companies and health plans
- Potential rationing of care due to high costs
These effects underscore the broader public health implications of pharmaceutical antitrust issues.
Legal and Regulatory Implications
The Xyrem antitrust litigation touches on several important legal and regulatory issues in the pharmaceutical industry.
Reverse Payment Settlements
The case highlights the ongoing scrutiny of reverse payment settlements, also known as "pay-for-delay" agreements. These settlements have been a focus of antitrust enforcement in recent years, with the Supreme Court's 2013 decision in FTC v. Actavis establishing that such agreements can violate antitrust laws.
REMS Abuse
The allegations of REMS abuse in this case underscore the potential for safety programs to be used as barriers to competition. This issue has attracted attention from both the FDA and FTC, with ongoing efforts to balance safety concerns with the need for generic competition.
Patent Strategies
The litigation also raises questions about the appropriate scope of pharmaceutical patents and the line between legitimate patent protection and anticompetitive conduct. The case may influence how courts and regulators view patent strategies in the pharmaceutical industry going forward.
