- Represented Vertex Pharmaceuticals, Inc. in a decision crystalizing the standard required to plead scienter in securities fraud cases, the First Circuit affirmed the dismissal of a securities class action complaint filed against Vertex and the company’s senior executives by Local No. 8 IBEW Retirement Plan and Trust. This decision ends four years of litigation defending against plaintiff’s false and unfounded allegations that Vertex’s disclosures regarding the results of clinical trials assessing the safety and efficacy of the company’s combination drug therapy for the treatment of patients with cystic fibrosis violated the federal securities laws. We successfully rebuffed plaintiffs twice in the District Court, ultimately securing victory in the First Circuit.
