The Complaint alleges that throughout the Class Period, Biogen issued false and misleading statements concerning the safety profile and growth prospects of Tecfidera, an immunosuppressant that is prescribed to treat multiple sclerosis (“MS”), and Biogen’s main driver of revenues at the time. The Company publicly praised Tecfidera’s attractive safety profile and solid growth trajectory, while aware that the drug weakened the immune system for MS patients, causing physicians to discontinue prescriptions of Tecfidera. On October 22, 2014, Biogen announced the death of a patient linked to Tecfidera. On April 24, 2015, the Company disclosed that the patient death announced in October 2014 was causing Tecfidera sales to grow “at an overall slower rate” but the long-term outlook “remain[ed] strong.” On July 24, 2015, Biogen abruptly cut its revenue guidance in half due to a revised growth expectation for Tecfidera based on safety concerns following the patient death. When this information was disclosed to the public, Biogen shares declined in value.
