In this multidistrict class action on behalf of purchasers of Cardizem CD, a brand-name heart medication, Plaintiffs alleged that an agreement between the brand name and generic manufacturers unlawfully stalled generic competition.  Judge Nancy Edmunds granted final approval to an $80 million settlement for the benefit of third-party payors, consumers and state agencies. In re Cardizem CD Antitrust Litig., 218 F.R.D. 508 (E.D. Mich. 2003), app. dismissed, 391 F.3d 812 (6th Cir. 2004).  The litigation resulted in several significant decisions, including: 105 F. Supp. 618 (E.D. Mich. 2000) (denying motions to dismiss); 105 F. Supp. 2d 682 (E.D. Mich. 2000) (granting plaintiffs’ motions for partial summary judgment and holding agreement per se illegal under federal and state antitrust law); 200 F.R.D. 326 (E.D. Mich. 2001) (certifying exemplar end-payor class); 332 F.3d 896 (6th Cir. 2003) (upholding denial of motion to dismiss and grant of partial summary judgment), cert. denied, 125 S.Ct. 307 (2004).
