NEW YORK, June 11, 2013 /PRNewswire/ -- Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Dynavax Technologies Corporation ("Dynavax" or the "Company") (NasdaqCM: DVAX -News). The investigation focuses on whether the Company and its executives violated federal securities laws. On June 10, 2013, shares of Dynavax fell as much as 42% after reporting its findings from a meeting with the Food and Drug Administration ("FDA") over its biologic license application for hepatitis-B vaccine Heplisav. Dynavax said the FDA wants it to get safety data from more patients. The agency added that analyzing the drug for smaller groups of patients did not fully address its concerns. In addition to understanding what the FDA would like to see in additional safety trials, Dynavax also has manufacturing concerns to contend with as noted by the FDA in its complete response letter to the company. The investigation focuses on whether a series of statements by the Company regarding its business, its prospects and its operations were materially false and misleading at the time they were made.
