The investigation by a law firm for NASDAQ:OPTR stockholders concerns whether certain directors and officers at Optimer Pharmaceuticals, Inc. (NASDAQ:OPTR) breached their fiduciary duties owed to NASDAQ:OPTR stockholders by improperly managing the company.

On April 9, 2012, Optimer Pharmaceuticals, Inc. reports its preliminary First Quarter 2012 financial results. Among other things, Optimer Pharmaceuticals, also disclosed that its board of Directors removed Dr. Michael Chang as Chairman and terminated John D. Prunty, Chief Financial Officer, and Dr. Youe-Kong Shue, Vice President. Optimer Pharmaceuticals said its board appointed Hank McKinnell as its new Chairman and that Kurt Hartman has been appointed acting CFO and a search for a permanent CFO has commenced. Optimer Pharmaceuticals said that Dr. Chang's removal as Chairman resulted from the Board's views as to his actions in his capacity as Optimer's representative on the Board of Directors of Optimer Biotechnology, Inc. ("OBI"), its 43%-owned independent, Taiwanese-based affiliate, as well as his failure to identify and effectively manage compliance, record keeping and conflict of interest issues in connection with OBI's grant to Dr. Chang, potentially for the benefit of a third party, of 1.5 million shares of OBI. Optimer Pharmaceuticals said that “the terminations of Mr. Prunty and Dr. Shue were related to the belief of Optimer's Independent Directors that both individuals failed to follow proper procedures when they became aware of the issues related to the issuance of the OBI shares to Dr. Chang.”
