Challenges in the design and conduct of clinical trials for Hospital-acquired pneumonia and ventilator-associated pneumonia: An industry perspective

Abstract

Hospital-acquired pneumonia and ventilator-associated pneumonia are associated with high rates of morbidity and mortality and are often caused by drug-resistant pathogens. Trials of potential new agents to treat these serious infections are complicated by various factors associated with their design and conduct and the complex underlying conditions of the patients that can potentially obscure determination of treatment benefits. Balancing scientific rigor and optimal patient management while maintaining logistical and financial feasibility is a challenge in the conduct of these studies. Regulatory guidance could help to standardize the design and conduct of trials evaluating potentially efficacious agents. In this article, some of the important challenges that were faced in conducting trials of agents to treat hospital-acquired pneumonia and ventilator-associated pneumonia are described, and areas for which regulatory guidance would be most useful are discussed. © 2010 by the Infectious Diseases Society of America.
