EPIX Pharmaceuticals Announces Resubmission of New Drug Application for Vasovist

LEXINGTON, Mass.--(BUSINESS WIRE)--Jul 1, 2008 - EPIX Pharmaceuticals, Inc., a biopharmaceutical company focused on discovering and developing novel therapeutics through the use of its proprietary and highly efficient in silico drug discovery platform, announced today that the New Drug Application (NDA) for its novel blood pool magnetic resonance angiography (MRA) agent, Vasovist (gadofosveset trisodium) was resubmitted to the U.S. Food and Drug Administration (FDA) on June 30, 2008.
