FDA extends CombinatoRx' Exalgo tablets NDA PDUFA review date

CombinatoRx, Incorporated (NASDAQ: CRXX) today announced that the U.S. Food and Drug Administration (FDA) has extended the Prescription Drug User Fee Act (PDUFA) goal date for review of the Exalgo™ (hydromorphone HCl) extended-release tablets New Drug Application (NDA) from Monday, February 22, 2010 to Monday, March 1, 2010 due to federal government closings.

The U.S. rights to Exalgo tablets were acquired from Neuromed by Mallinckrodt Inc., a Covidien company, in June, 2009. Neuromed acquired the U.S. marketing rights to Exalgo tablets from ALZA Corporation in April 2007 and was responsible for clinical development and regulatory filings. Covidien is responsible for all commercialization activities for Exalgo in the U.S., including marketing, sales and all post-approval FDA regulatory filings, and will now own the intellectual property for the product. ALZA is responsible for manufacturing, packaging and supply of the product. CombinatoRx and Neuromed merged on December 21, 2009.
