Epix Pharmaceuticals' CEO quits

The chief executive of Epix Pharmaceuticals Inc., Michael G. Kauffman, has resigned, the Lexington biotech said today. The company's board of directors appointed Elkan Gamzu to serve as interim chief executive effective, according to a press release.

"I am pleased to undertake this opportunity to lead Epix at this important time in its history," Gamzu said.

Kauffman joined Epix in August 2006 when it bought Predix Pharmaceutical Holdings Inc., where he had served as chief executive since September 2002.

In June, Epix resubmitted an application to the Food and Drug Administration for Vasovist, a blood imaging agent. Gamzu said the company will continue to work with the FDA to win approval for the drug.

A consultant to the biotechnology and pharmaceutical industries, Gamzu has previously held leadership positions, including as chief executive of Pharmos Corp. He has worked in the pharmaceutical industry since 1971.
