FDA Asks for More Information to OK Theravance, Inc. (THRX) Skin Disease Drug


10/22/2007 6:23:30 AM

SOUTH SAN FRANCISCO, CA and DEERFIELD, IL--(MARKET WIRE)--Oct 22, 2007 -- Theravance, Inc. (NasdaqGM:THRX - News) and Astellas Pharma US, Inc. announced today that the U.S. Food and Drug Administration (FDA) issued an Approvable Letter for telavancin, a novel bactericidal, once-daily injectable antibiotic discovered by Theravance, for the treatment of complicated skin and skin structure infections (cSSSIs) caused by Gram-positive bacteria, including resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA).

The Approvable Letter indicates that the telavancin application is approvable, subject to: resolution of current good manufacturing practices (cGMP) compliance issues not specifically related to telavancin at a third-party manufacturer; and submission of revised labeling or re-analyses of clinical data or additional clinical data. Theravance and Astellas believe that no additional clinical studies will need to be initiated to respond to the Approvable Letter.

"We are committed to submitting a timely and complete response to this Approvable Letter," said Rick E Winningham, Chief Executive Officer of Theravance. "We will work with the FDA to resolve the outstanding issues and to ensure a label that accurately reflects the data from our clinical studies, which included the largest group of patients with cSSSI and the largest group of patients infected with MRSA ever studied. Recent reports from the Centers for Disease Control and Prevention, the subject of an article and editorial in the Journal of the American Medical Association concerning MRSA infections, only serve to highlight the urgent need for additional therapeutic options."
