Telavancin: A Novel Lipoglycopeptide Antibiotic

Abstract

Objective To review the pharmacology, antimicrobial activity, pharmacokinetics, clinical applications, and safety of telavancin, a new lipoglycopeptide antibiotic. Data Sources Literature was obtained from MEDLINE (1966–April 2009) and International Pharmaceutical Abstracts (1971–April 2009) using the search terms telavancin and TD-6424, and also from Theravance, Inc., and Astellas Pharma US, Inc. Study Selection And Data Extraction Available English-language articles were reviewed, as well as information obtained from Theravance, Inc., and Astellas Pharma US, Inc. Data Synthesis Telavancin has rapid bactericidal activity against gram-positive aerobic and anaerobic bacteria through multiple mechanisms of action. In vitro and Phase 2 in vivo data support the efficacy of telavancin against antibiotic-resistant gram-positive organisms. On March 4, 2008, the Food and Drug Administration (FDA) accepted as complete for review Theravance's response to the October 19, 2007, New Drug Application approvable letter for telavancin to be used as treatment for complicated skin and skin structure infections (cSSSIs) caused by gram-positive bacteria. QTc interval prolongation has been reported, although the clinical impact of this has not been determined. Drug interactions have not been identified as of yet. Conclusions Telavancin is currently under review by the FDA for the treatment of cSSSIs caused by gram-positive bacteria. The completion of Phase 3 trials will determine whether telavancin will have a role in the treatment of other infections caused by resistant gram-positive bacteria.
