| 99.1 | Press Release of Theravance, Inc. dated November 27, 2009 |
SOUTH SAN FRANCISCO, CA -- (Marketwire - November 27, 2009) - Theravance, Inc. (NASDAQ: THRX) announced today that it received a Complete Response letter from the U.S. Food and Drug Administration (FDA) related to the telavancin New Drug Application (NDA) for the treatment of nosocomial pneumonia (NP). Telavancin is a bactericidal, once-daily injectable investigational antibiotic for the treatment of NP caused by Gram-positive bacteria such as methicillin-resistant Staphylococcus aureus (MRSA). VIBATIV™ (telavancin) is approved in the United States and in Canada for the treatment of adult patients with complicated skin and skin structure infections (cSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible and -resistant isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group (includes S. anginosus, S. intermedius and S. constellatus) and Enterococcus faecalis (vancomycin-susceptible isolates only).
The Complete Response instructed Theravance that submission of additional data and analyses for the NP patient population to support an evaluation of all-cause mortality as the primary efficacy endpoint is necessary to demonstrate the safety and efficacy of telavancin. The telavancin NP clinical trials included clinical response as the primary endpoint, consistent with current draft FDA guidelines for antibacterial clinical trial design in NP, and all-cause mortality as a secondary endpoint. In the Complete Response, the FDA also requested further rationale for the pooling of the data from the two ATTAIN studies, noted the need for a pediatric drug development plan for the NP indication and a customary safety update. If the additional data and analyses that Theravance submits to the FDA are deemed insufficient, FDA may not approve the NDA or may require that additional studies be conducted.
"The requests in the Complete Response Letter are generally in line with our expectations, and we believe these requests can be addressed promptly," said Rick E Winningham, Chief Executive Officer. "We believe that we have already collected the information and completed the analyses required to respond to the FDA. Importantly, the additional data collected to date support our prior conclusions about the telavancin ATTAIN studies. We look forward to submitting our response and continuing to work with the FDA on this NDA."
Theravance previously indicated that the FDA's review of the telavancin NDA was likely to extend into 2010. The initial Prescription Drug User Fee Act (PDUFA) date for action by FDA was November 26, 2009.

About Telavancin
Telavancin was discovered by Theravance in a research program dedicated to finding new antibiotics for serious infections due to Staphylococcus aureus and other Gram-positive bacteria, including MRSA. Telavancin is a bactericidal, once-daily, injectable lipoglycopeptide antibiotic with a dual mechanism of action whereby telavancin both inhibits bacterial cell wall synthesis and disrupts bacterial cell membrane function. The U.S. Food and Drug Administration is currently reviewing the telavancin NDA for the treatment of NP.
About the Clinical Studies
The NDA is based on data from the ATTAIN I and II clinical studies in adult patients. ATTAIN I and ATTAIN II were two large, multi-center, multinational, double-blind, randomized Phase III clinical studies, in which 1,503 patients were enrolled and treated, 464 of whom were infected with MRSA. Patients with NP suspected or proven to be caused by Gram-positive bacteria were randomized (1:1) to receive either telavancin 10 mg/kg IV once daily or vancomycin 1 g IV every 12hr (the protocols allowed vancomycin dosage to be modified per site-specific guidelines). For patients with suspected or proven polymicrobial infections involving Gram-negative and/or anaerobic bacteria in addition to the Gram-positive organisms for which study medication therapy was used, aztreonam, piperacillin-tazobactam, and/or metronidazole were allowed. The objective of each study was non-inferiority of telavancin versus vancomycin in clinical cure rate at the test-of-cure visit. Determination of clinical cure was based upon physician-judged resolution of clinical signs and symptoms of NP. In both studies, telavancin achieved the objective of non-inferiority in the all-treated (AT) and clinically evaluable (CE) patient populations.
Important Safety Information
Fetal Risk
Women of childbearing potential should have a serum pregnancy test prior to administration of VIBATIV. Avoid use of VIBATIV during pregnancy unless the potential benefit to the patient outweighs the potential risk to the fetus. Adverse developmental outcomes observed in three animal species at clinically relevant doses raise concerns about potential adverse developmental outcomes in humans. If not already pregnant, women of childbearing potential should use effective contraception during VIBATIV treatment.
Nephrotoxicity
New onset or worsening renal impairment occurred in patients who received VIBATIV. Renal adverse events were more likely to occur in patients with baseline comorbidities known to predispose patients to kidney dysfunction and in patients who received concomitant medications known to affect kidney function. Monitor renal function in all patients receiving VIBATIV prior to initiation of treatment, during treatment, and at the end of therapy. If renal function decreases, the benefit of continuing VIBATIV versus discontinuing and initiating therapy with an alternative agent should be assessed. Clinical cure rates in telavancin-treated patients were lower in patients with baseline CrCl less than or equal to 50 mL/min compared to those with CrCl greater than 50 mL/min. Consider these data when selecting antibacterial therapy for use in patients with baseline moderate/severe renal impairment.
Geriatric Use
Telavancin is substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection in this age group.
Infusion Related Reactions
VIBATIV is a lipoglycopeptide antibacterial agent and should be administered over a period of 60 minutes to reduce the risk of infusion-related reactions. Rapid intravenous infusions of the glycopeptide class of antimicrobial agents can cause "Red-man Syndrome"-like reactions including: flushing of the upper body, urticaria, pruritus, or rash.
Clostridium difficile-Associated Diarrhea
Clostridium difficile-associated diarrhea (CDAD) has been reported with nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis. CDAD must be considered in all patients who present with diarrhea following antibiotic use.
Development of Drug Resistant Bacteria
Prescribing VIBATIV in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. As with other antibacterial drugs, use of VIBATIV may result in overgrowth of nonsusceptible organisms, including fungi.
QTc Prolongation
Caution is warranted when prescribing VIBATIV to patients taking drugs known to prolong the QT interval. In a study involving healthy volunteers, VIBATIV prolonged the QTc interval. Use of VIBATIV should be avoided in patients with congenital long QT syndrome, known prolongation of the QTc interval, uncompensated heart failure, or severe left ventricular hypertrophy.
Coagulation Test Interference
VIBATIV does not interfere with coagulation, but does interfere with certain tests used to monitor coagulation such as prothrombin time, international normalized ratio, activated partial thromboplastin time, activated clotting time, and coagulation based factor Xa tests. Blood samples for these coagulation tests should be collected as close as possible prior to a patient's next dose of VIBATIV.
Adverse Reactions
The most common adverse reactions (greater than or equal to 10% of patients treated with VIBATIV) observed in the Phase III cSSSI clinical trials were taste disturbance, nausea, vomiting, and foamy urine.
In the Phase III cSSSI clinical trials, serious adverse events were reported in 7% of patients treated with VIBATIV and most commonly included renal, respiratory, or cardiac events. Serious adverse events were reported in 5% of vancomycin-treated patients, and most commonly included cardiac, respiratory, or infectious events.
