Shapiro Haber & Urmy LLP and Liggio Benrubi PA filed a class action on July 26, 2013 against Accentia Biopharmaceuticals, Inc. (“Accentia”) (ABPI) and certain officers and directors of Accentia and Biovest International, Inc. (“Biovest”) (OTCQB:BVTI), a majority-owned subsidiary of Accentia, for violations of federal securities laws. The case has been filed in the United States District Court for the Middle District of Florida and is entitled Hill v. Accentia Biopharmaceuticals, et al., C.A. No. 13-cv-01945.

The Complaint alleges that the FDA informed Biovest that the results of a Phase III clinical trial for BiovaxID, a potential vaccine for the treatment of non-Hodgkin’s lymphoma, did not support an application for approval of BiovaxID. Despite this information, Defendants made numerous statements in press releases and securities filings that gave the misleading impression that the trial results were statistically significant and that Biovest was on track to obtain FDA approval. The Complaint alleges that these misstatements and omissions by Defendants misrepresented and/or omitted material facts to the investing public, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act.

The class action is brought on behalf of all persons and entities who purchased common stock of either Accentia or Biovest from July 26, 2008 through August 14, 2012.

If you purchased shares of either Biovest or Accentia common stock during the above time period, you may move the court to appoint you as lead plaintiff no later than 60 days from today.
