Optimer Pharmaceuticals Inc. (OPTR) said it has begun exploring a "full range" of strategic options and also named Chairman Henry McKinnell as its new chief executive, part of a larger overhaul of top management.

Shares jumped 10% to $11.83 in recent premarket trading. Through Tuesday's close, the stock has fallen 18% in the past 12 months.

Current CEO Pedro Lichtinger--who had served in the role since May 2010--has agreed to step down as CEO, president and a board member. Mr. McKinnell will serve as CEO for the duration of the strategic review process.

Optimer--which also unveiled a shareholder rights plan--said its General Counsel and Chief Compliance Officer Kurt Hartman has agreed to step down and will be replaced by Meredith Schaum.

Additionally, the company has named Mark Auerbach, who has served as an Optimer director since June 2005, as its lead independent director.

The changes come after Optimer in April fired Chief Financial Officer John D. Prunty and Vice President Youe-Kong Shue. It also removed Michael Chang as board chairman and asked him to resign in connection with his relationship with Optimer Biotechnology Inc., Optimer's 43%-owned Taiwanese-based affiliate.

Optimer said Mr. Chang's removal as chairman stemmed from his failure to identify and effectively manage compliance and conflict of interest issues in connection with Optimer Biotechnology's grant to him of 1.5 million shares, which Optimer said was "potentially for the benefit of a third party."

Optimer said it had fired Mr. Prunty and Dr. Shue because both individuals failed to follow proper procedures when they became aware of the issues related to the issuance of the shares to Mr. Chang.

Optimer said Wednesday that the latest management changes were "appropriate" following a review of prior compliance, record keeping and conflict-of-interest issues observed during the review.

Optimer added that previously disclosed investigations of the issues by U.S. authorities are ongoing and it continues to cooperate with those authorities.

Optimer has hired J.P. Morgan and Centerview Partners as its financial advisers and Sullivan & Cromwell LLP as its legal advisers regarding the strategic review.

The company plans to report fourth-quarter results Thursday.
