Aeterna Zentaris Is Accused of Misleading Investors

According to the complaint, shares of Aeterna Zentaris fell $0.64 per share, or nearly 50%, to close at $0.65 on November 6, 2014, after the company announced that it had received a Complete Response Letter from the U.S. Food and Drug Administration ("FDA") refusing to approve its New Drug Application for Macrilen, an oral product used for evaluating adult growth hormone deficiency. The complaint alleges that the FDA refused to approve Macrilen, in part, because the "planned analysis of the Company's pivotal trial did not meet its stated primary efficacy objective as agreed to in the Special Protocol Assessment agreement letter between the Company and the FDA." Moreover, the FDA's letter noted a lack of sufficient data to demonstrate that patients in the clinical trial had been accurately diagnosed with adult growth hormone deficiency.

The complaint further alleges that Aeterna Zentaris made false and/or misleading statements and failed to disclose material adverse facts about the company's business, operations, and prospects that rendered the foregoing statements misleading and/or lacking a reasonable basis.
