Telavancin Hospital-Acquired Pneumonia Trials: Impact of Gram-Negative Infections and Inadequate Gram-Negative Coverage on Clinical Efficacy and All-Cause Mortality

Abstract

In the ATTAIN safety population there were 16 more deaths in the telavancin arms than in the vancomycin arms. Of these, 13 were in patients with gram-negative-only infections (n = 9) or with mixed infections and inadequate GNC (n = 4) and all had estimated baseline creatinine clearances of <30ml/min. Based on this analysis, clinical response and all-cause mortality could be confounded because there were more patients with gram-negative pathogens at baseline and more patients received inadequate treatment of these gram-negative infections in the telavancin groups.
