In a recently filed federal class action complaint, Dynavax and certain of its officers and directors were charged with violating certain provisions of the Securities Exchange Act of 1934. Specifically, the complaint alleges that among other things, defendants’ misrepresented and/or failed to disclose that: (a) the clinical trial for HEPLISAV was flawed since the trial demographics did not represent the population of the United States; (b) the trial did not have a one-year safety follow-up, which is typically required for vaccines; (c) the trial lacked information concerning concomitant use with other vaccines; (d) given the novel adjuvant that the HEPLISAV vaccine contains, the clinical trial for HEPLISAV was flawed because the safety database size was inadequate to rule out rare adverse autoimmune events; (e) Dynavax failed to provide the FDA with sufficient data concerning its manufacturing processes and controls for HEPLISAV on its BLA; and (f) as a result of the above, the Company’s positive statements about the Company’s outlook, including the statements about its launch of HEPLISAV in 2013, were materially false or misleading. According to the complaint, when the true facts were revealed, the Company’s shares dropped 73% from their Class Period high.
