Acusphere, Inc. Appoints Michael Slater SVP Regulatory Affairs and Operations Replacing Dennis Bucceri
WATERTOWN, Mass., September 25, 2008 --- Acusphere, Inc. (NASDAQ: ACUS) today announced that Michael R. Slater will assume the position of Senior Vice President, Regulatory Affairs and Operations effective September 29, 2008, following the decision of Dennis Bucceri to leave the company for another opportunity. Mr. Slater, currently Senior Vice President, Operations, oversaw regulatory affairs at Acusphere prior to Mr. Bucceri’s appointment in 2007. He has also held this position in other companies, including Biogen and Anika Therapeutics.
Sherri C. Oberg, President and CEO of Acusphere, said, “We are disappointed to lose Dennis, but respect his decision to return to a larger, more established company. We are confident that Michael Slater will be able to effectively step back into the regulatory affairs role and continue to push forward with the remaining critical milestones in the review and ultimately approval by the U.S. Food and Drug Administration (FDA) of our lead product, Imagify™. As I’ve said before, Greater Boston is a competitive arena for experienced biotech management. Dennis’ role in shepherding Imagify, one of the few blockbuster products currently moving through FDA review, makes him highly attractive to a host of other larger companies. We thank him and wish him continued success.”
The expected target action date for Imagify (Perflubutane Polymer Microspheres) for Injectable Suspension, under the Prescription Drug User Fee Act (PDUFA) is February 28, 2009.
