United States Food and Drug Administration draft guidance for future antibiotic clinical trials of bacterial nosocomial pneumonia (NP) recommends using diagnostic criteria from the American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines, and using a primary end point of 28-day all-cause mortality. The effect of applying these guidelines on outcomes of the phase III NP studies of telavancin was evaluated in a post-hoc analysis. ATS/IDSA criteria were applied in a blinded fashion to the original all-treated (AT) group. Clinical cure rates at final follow-up were determined in the refined AT and clinically-evaluable (CE) groups (ATS/IDSA-AT and ATS/IDSA-CE, respectively). Exploratory end point of 28-day survival was evaluated in the ATS/IDSA-AT group. Non-inferiority of telavancin versus vancomycin was demonstrated, with similar cure rates in the ATS/IDSA-AT (59% versus 59%, respectively) and ATS/IDSA-CE groups (83% versus 80%, respectively). Cure rates favored telavancin in ATS/IDSA-CE patients where Staphylococcus aureus was the sole pathogen (86% versus 75%). Overall, 28-day survival was similar in the telavancin (76%) and vancomycin (77%) groups, but lower in telavancin-treated patients with pre-existing moderate-to-severe renal impairment (CLCR <50 ml/min). Telavancin should only be administered to patients with moderate-to-severe renal impairment if treatment benefit outweighs risk, or if no suitable alternatives are available.
