A federal appeals court has rejected class certification for third-party payers who claim Eli Lilly and Co. made misrepresentations about the effectiveness and safety of the drug Zyprexa.

The 2nd U.S. Circuit Court of Appeals reversed Eastern District of New York Judge Jack B. Weinstein, who in 2008 had certified a class of third-party payers, such as insurance providers, who claimed Lilly’s misrepresentations caused them to overpay for Zyprexa between June 20, 2001, to June 20, 2005.
