Theravance Announces Additional Results From Successful Phase 3 Telavancin Complicated Skin and Skin Structure Program

SOUTH SAN FRANCISCO, CA--(Healthcare Sales & Marketing Network)--Oct 10, 2006 -- Theravance, Inc. (NASDAQ:THRX ) today announced additional results from its ATLAS 1 and ATLAS 2 studies assessing the safety and efficacy of telavancin, a rapidly bactericidal injectable antibiotic with multiple mechanisms of action, in the treatment of complicated skin and skin structure infections (cSSSI) caused by Gram-positive bacteria. The data will be presented today at the Third International Symposium on Resistant Gram-Positive Infections in Niagara-on-the-Lake, Ontario.

ATLAS 1 and ATLAS 2 were two large, multi-center, multinational, double-blind, randomized Phase 3 clinical studies that enrolled and treated 1,867 patients in total, 719 of whom were infected with methicillin-resistant Staphylococcus aureus (MRSA).

In the combined ATLAS 1 and ATLAS 2 studies, patients with cSSSI were randomized (1:1) to receive either telavancin 10 mg/kg IV once daily or vancomycin 1 gm IV q 12hr (dosages adjusted per site specific guidelines) for 7-14 days. Evaluations of efficacy were performed at a follow-up visit that occurred 7-14 days following the end of treatment. Of the patients enrolled and treated, approximately 80% were clinically evaluable and approximately 70% were microbiologically evaluable. Mean age of the patients was approximately 49 years, 25% were diabetic, and 12% had moderate to severe renal insufficiency at baseline. Approximately 80% of the patients had a major abscess or deep, extensive cellulitis. Staphylococcus aureus was the most common baseline pathogen with the majority of the isolates being methicillin-resistant strains.

Key findings were as follows:

The primary efficacy endpoint of non-inferiority in the clinical cure rate at the follow-up visit, comparing telavancin to vancomycin, was achieved in both studies, and the rates of clinical cure, microbiological eradication, and overall therapeutic response for telavancin compared favorably to those for vancomycin.

In the combined data from both studies in patients with MRSA, clinical cure rates, microbiologic eradication rates and overall therapeutic response (combination of clinical cure + microbiologic eradication) favored telavancin over vancomycin:
Telavancin      Vancomycin   95% confidence
                          total success  total  success

     Clinical Cure         278   90.6%    301    86.4%   (-1.1, 9.3)

     Eradication           278   89.9%    301    85.4%   (-0.9, 9.8)

     Therapeutic Response  278   89.9%    301    84.7%   (-0.3, 10.5)
The most common adverse events reported in patients receiving telavancin were taste disturbance (telavancin 33% versus vancomycin 7%), nausea (telavancin 27% versus vancomycin 15%), and vomiting (telavancin 14% versus vancomycin 7%). Less than 1% of these events were judged to be severe. Renal adverse events occurred in 2.5% of telavancin patients versus 0.5% of vancomycin patients. In patients with a serious renal adverse event, which occurred in less than 1% of patients in both groups, the event had resolved, or was resolving, at the last visit. Prolongation of the QTc interval from pre-treatment values by greater than 60 msec occurred in 1% of the telavancin group versus 0.5% of the vancomycin group. QTc interval of greater than 500 msec occurred in one telavancin patient versus two vancomycin patients. No cardiac events were attributable to QTc prolongation.

"Staphylococcal infections, and in particular those caused by methicillin-resistant Staph. aureus bacteria, are becoming a more frequent and serious medical problem," said Dr. G. Ralph Corey of Duke Clinical Research Institute, the principal investigator in the ATLAS program. "Results demonstrated clinical, microbiological, and overall therapeutic response that consistently favored telavancin over vancomycin. Importantly, telavancin has a safety profile that is compatible with treatment of serious infections due to resistant bacteria. These are important and encouraging findings in this area of increasing medical need."
