Manufacturing problems cause shortage of Theravance-developed superbug drug

Manufacturing problems at a third-party manufacturer have led to “critical” shortages of the serious skin infection drug Vibativ, developed by South San Francisco-based Theravance Inc.
Astellas Pharma US, which is marketing the drug, told wholesalers and distributors Friday that no new patients should be started on Vibativ, according to a Securities and Exchange Commission filing Friday by Theravance (NASDAQ: THRX).
Vibativ, a once-daily injectable drug to treat Gram-positive bacteria, including the MRSA “superbug,” was approved in the United States in September 2009. It won European approval this past September.
