The complaint alleges that the Company misled investors to believe that the pre-clinical and clinical trial data for its developmental drug lorcaserin, or Lorqess, indicate it is a safe therapy for weight management.
On September 14, 2010, the FDA disclosed that lorcaserin caused cancer in rats in certain preclinical studies.
As a result of this adverse news, Arena shares declined from a close of $6.85 per share on September 13, 2010, to close at $4.13 per share on September 14, a decline of $2.71 per share or approximately 40%. On September 16, 2010, the Wall Street Journal reported a federal advisory panel rejected lorcaserin. On September 17, 2010, Arena shares declined an additional $1.99 per share or approximately 47%, causing investors substantial losses.
