The Ninth Circuit recently revived a securities class action against Arena Pharmaceuticals, issuing a decision with important guidance to pharmaceutical companies speaking publicly about future prospects for FDA approval of their advanced drug candidates. The court’s opinion reemphasizes the dangers of volunteering incomplete information, holding that a company that touts the results of trials or tests as supportive of a pending application for FDA approval must also disclose negative test results or concerns expressed by the FDA about those studies—even if the company reasonably believes the concerns are unfounded and are the product of a good faith disagreement.
Second Circuit Applies Omnicare to Affirm Dismissal of Securities Fraud Actions
On March 4, 2016, the Second Circuit affirmed the dismissal of two related securities actions against Sanofi Pharmaceuticals, its predecessor Genzyme Corporation, and three company executives (collectively, “Sanofi”). In doing so, the Second Circuit offered its first substantial interpretation of the Supreme Court’s March 2015 decision in Omnicare, Inc. v. Laborers District Council Construction Industry Pension Fund, 135 S. Ct. 1318 (2015), which addresses how plaintiffs can allege securities claims based on statements of opinion.
