Notable Cases

  • $72.5 Million Recovery in Solodyn Antitrust Action
    In July 2018, the Honorable Denise J. Casper of the District of Massachusetts granted final approval to a $72.5 million class settlement for direct purchasers of brand and generic Solodyn. HBSS was co-lead class counsel in this case alleging Medicis entered into a series of reverse payment deals to delay entry of generic Solodyn and used the period of delay to effectuate a product hop, all resulting in overcharges by direct purchasers. The case settled three days before trial.
    In re Solodyn Antitrust Litigation, D. Mass., MDL No. 2503
  • Antitrust action for direct purchasers of Skelaxin
    On Sept. 24, 2014, Judge Curtis Collier of the Eastern District of Tennessee approved a $73 million settlement for direct purchasers of Skelaxin in litigation alleging Skelaxin’s manufacturer colluded with would-be generic competitors, fraudulently delaying generic competition and leading to higher prices. Metaxalone was sold under the brand name Skelaxin since 1962, but the original patent expired in 1979. Manufacturers applied to market generic metaxalone in 2002, and generic competitors remained foreclosed from marketing generic metaxalone until 2010. Hagens Berman served as lead counsel for direct purchasers.
    In re Skelaxin (Metaxalone) Antitrust Litigation, E.D.TN., Civil Action No. 1:12-md-2343.
  • Health care coverage for 40,000 legal immigrants in Massachusetts
    On Jan. 5, 2012, the Massachusetts Supreme Judicial Court ruled unanimously that a state law barring 40,000 low-income legal immigrants from the state’s universal health care program unconstitutionally violates those immigrants’ rights to equal protection under the law and must be struck down. Hagens Berman served as pro bono counsel.
    Finch v. Commonwealth Health Insurance Connector Authority, Mass., Civil Action No. SJC-11025.
  • $25 million for the state of Connecticut for Zyprexa fraud
    On Oct. 5, 2009, U.S. District Court Judge Jack B. Weinstein approved a $25 million settlement reached by the parties to conclude the state’s Zyprexa litigation that alleged Lilly engaged in unlawful off-label promotion and misrepresented Zyprexa’s safety and efficacy, resulting in millions of dollars in excess pharmaceutical costs. Hagens Berman served as outside counsel to Attorney General Richard Blumenthal.
    State of Connecticut v. Eli Lilly & Co., E.D.N.Y., Civil Action No. 08-cv-955-JBW.

Personal Insight

Unlike many of her colleagues at HBSS, Lauren does not run marathons – unless chasing after her small children counts. Lauren did wrestle in college but refused to don the wrestling singlet. Whenever she can, Lauren rock climbs with her in-laws, breathes deeply at yoga, and hosts dinner parties to, despite usual advice, try totally new recipes. She also keeps the pizza delivery guy on speed dial as back-up for such occasions.
