Nuvigil and EpiPen Litigation (Teva Pharmaceuticals)

  • Should be Empty:

Dena Burge, et al. v. Teva Pharmaceuticals Industries, Ltd., et al. Case No. 2:22-cv-02501
United States District Court for the District of Kansas

Mary Pennington, et al. v. Teva Pharmaceuticals Industries, Ltd., et al., Case No. 2:25-cv-02737
United States District Court for the District of Kansas
 

Case Status

On March 24, 2024, the Court denied the Defendants’ motion to dismiss in Burge, mostly allowing Plaintiffs’ claims to proceed. 

On October 7, 2025, after reviewing documents in camera that Defendants had withheld for privilege, the Magistrate Judge ordered Defendants to provide a number of those documents to Plaintiffs. The Magistrate Judge held that those documents were probative of allegations of active and intentional fraudulent concealment by Defendants with the participation of their attorneys. The District Court Judge affirmed the Magistrate Judge’s Order on January 14, 2026. 

On February 20, 2026, Plaintiffs in Pennington filed a consolidated class action complaint in the U.S. District Court for the District of Kansas. 

On March 20, 2026, Defendants moved to dismiss the Pennington case. Plaintiffs filed their opposition on April 20, 2026, and Defendants filed their reply to the opposition on May 11, 2026. We await the Court’s order on this briefing. 

On April 4, 2026, Teva filed a motion for summary judgment in Burge. Plaintiffs filed their opposition on June 12, 2026.

Case Overview

On December 2, 2022, Keller Rohrback L.L.P. and its co-counsel filed a class action complaint (in the Burge case) alleging that Teva Pharmaceuticals Industries, Ltd. and its subsidiaries, among others, participated in a scheme to improperly block access to two different pharmaceutical products: a generic version of Teva’s branded drug Nuvigil and a generic version of the EpiPen, a life-saving drug/device combination for the treatment of severe allergic reactions. Nuvigil is a critical medication used to reduce extreme sleepiness caused by narcolepsy, sleep apnea, and other sleep-related conditions. In addition to those afflicted by sleep disorders, hospital workers, truck drivers, fire fighters, and many others rely on Nuvigil to keep them awake when working unconventional hours.

Plaintiffs allege that Teva signed secret deals with other pharmaceutical manufacturers to restrict market access for lower-cost alternatives to EpiPen and Nuvigil. They allege these deals allowed both sides to protect their respective monopolies by delaying entry of generic competition for their respective branded drugs for several years longer than legally allowed. As a result of this conspiracy, Plaintiffs allege, Teva was able to keep Nuvigil’s price high and enrich itself at the expense of American health plan payors and consumers who overpaid by hundreds of millions—if not billions—of dollars for the drug. A month’s supply of Nuvigil currently costs between $389–$1,151, depending on dosage.

The Burge action is pending in the U.S. District Court for the District of Kansas. Since Burge began, Keller Rohrback L.L.P. and its co-counsel have also brought two additional cases against Teva, concerning the same conduct as it affected individuals in other states. Initially filed in New York and California, those cases have been transferred to the District of Kansas and consolidated as the Pennington case. Pennington is assigned to the same judge and magistrate judge who preside over Burge.

A previous action concerning the pricing, sales practices, and marketing of the EpiPen, against different defendants, has already resulted in settlements totaling $609 million. See In re EpiPen Marketing, Sales Practices, & Antitrust Litigation, 17-md-2785 (D. Kan.) (see Keller Rohrback’s webpage on that case). That settlement, however, addressed only the EpiPen and concerned only certain companies’ roles in the pay-for-delay scheme. The Burge and Pennington cases address the other participant in the scheme, Teva, and the other side of the exchange: Nuvigil.
