On June 3, 2020, Judge Jan E. DuBois of the United States District Court for the Eastern District of Pennsylvania denied the End-Payor Plaintiffs’ (“EPPs”) motion for class certification in a multidistrict litigation (“MDL”) challenging the settlement practice of pay-for-delay.  In re Niaspan Antitrust Litig., No. 13-MD-2460, 2020 WL 2933824 (E.D. Pa. June 3, 2020).  The district court denied the EPPs’ motion for class certification because the EPPs failed to demonstrate, by a preponderance of the evidence, the requirements of ascertainability, predominance, and superiority.
