Schwartz v. Arena Pharmaceuticals, Inc.

by
Plaintiff filed a putative securities class action against defendants in connection with public statements made about Arena’s weight-loss drug, lorcaserin. When Arena filed its application with the FDA, the FDA’s advisory panel published a briefing document that disclosed, for the first time, that Arena had been in a “highly unusual” back-and-forth with the FDA regarding the results of cancer studies on rats (the “Rat Study”). Plaintiff filed suit after news of the Rat Study broke. The district court dismissed the First, Second, and Proposed Third Amended Complaints. The court agreed that once defendants touted the safety and likely approval of the drug based on animal studies, defendants were obligated to disclose the Rat Study's existence to the market. The court concluded that plaintiff has alleged scienter with sufficient particularity to survive a motion to dismiss. In this case, there is no question that plaintiff has alleged that defendants knew that the Rat Study existed, that defendants knew that the FDA’s request for bi-monthly reports and follow-up studies was highly unusual and out-of-process, and defendants went ahead and told investors about their confidence in lorcaserin’s approval based on preclinical animal studies. Therefore, the court concluded that plaintiff has properly pleaded scienter under Federal Rule of Civil Procedure 9(b) and the Private Securities Litigation Reform Act (PSLRA), 15 U.S.C. 78u-4. The court reversed and remanded. View "Schwartz v. Arena Pharmaceuticals, Inc." on Justia Law
