SOUTH SAN FRANCISCO, CA -- (MARKET WIRE) -- January 03, 2007 -- Theravance, Inc. (NASDAQ: THRX) announced today that the first patient was dosed in a Phase 2 clinical study of TD-1792, an investigational heterodimer antibiotic, for the treatment of complicated skin and skin structure infections (cSSSI) caused by Gram-positive bacteria, including resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA).
