- In re Seroquel Antitrust Litigation (D. Del.): Cohen Milstein represents End-Payor Plaintiffs who allege that Defendant AstraZeneca Pharmaceuticals LP struck deals with generic drug manufacturers Handa Pharmaceuticals LLC, Par Pharmaceutical Inc., and Accord Pharmaceuticals Inc., inducing the generics to delay launching generic versions of Seroquel XR, AstraZeneca's prescription drug treatment for schizophrenia, bipolar disorder, and depression, for five years in exchange for AstraZeneca committing to delay the launch of its own authorized generic.
- In re Lipitor Antitrust Litigation (D.N.J.): Cohen Milstein represents End-Payor Plaintiffs who allege that Defendant Pfizer, the manufacturer of the cholesterol drug Lipitor, the best-selling drug in pharmaceutical history, conspired with Ranbaxy, the generic manufacturer, to delay its introduction of a generic Lipitor product.
