CTTI Paper Highlights Clinical Criteria that Can Help Identify Patients at High Risk of HABP/VABP

Although treatment of possible nosocomial pneumonia is common with patients in the intensive care unit (ICU) receiving respiratory support, more than half of those treated do not fit the standard clinical definitions of hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP). A new CTTI paper available online in CHEST® Journal, accompanied by an insightful editorial, “Heeding the Prophetic Call,” outlines how the use of simple clinical criteria may help to identify high-risk patients earlier and aid future research to improve prevention and treatment.

 

The paper highlights the Prospective Identification of Pneumonia in Hospitalized Patients in the ICU (PROPHETIC) study, a large, contemporary, prospective cohort clinical trial designed by CTTI that made several key observations.

 

“HABP/VABP is associated with high mortality and morbidity and may be caused by multidrug-resistant pathogens,” said John Farley, director of the Office of Infectious Diseases at the FDA.   “Conducting clinical trials in HABP/VABP is challenging, and data to understand the patient population is critical to improve trial feasibility.”

The study sought to define the incidence of HABP/VABP in an ICU population and identify characteristics associated with the development of HABP/VABP to inform the design and conduct of future clinical trials.

The study determined that 32 percent of 4,613 prospectively identified high-risk patients received antibiotics for possible HABP/VABP. It was also determined that only 12 percent of the aforementioned high-risk patients fit the FDA Guidance standard clinical definition of HABP/VABP.

“These findings indicate that the burden of HABP and VABP is significant and there is also some concern about antibiotic overprescription in this high-risk population,” said Vance Fowler, professor of medicine at Duke University. “Receiving antibiotics is itself a risk factor for developing pneumonia, carries risks of adverse events, and may preclude eligibility for HABP/VABP clinical trial enrollment.”

Additionally, the manuscript highlights the common characteristics and treatment exposures researchers identified that were associated with increased odds of developing HABP/VABP in high-risk patients.

“Application of the study results to prospectively identify patients at highest risk for HABP/VABP may help to facilitate the conduct of innovative and efficient clinical trials,” said Pamela Tenaerts, executive director of CTTI. “This will help to promote development of optimal preventive, diagnostic, and treatment strategies to improve management of this disease.”

Clinical trials of new antibacterial drugs for hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) are critically needed but challenging to conduct.  

Building on our streamlining HABP/VABP trials work, CTTI conducted a prospective, multi-center, observational study of the risk factors for HABP/VABP, with over 6,700 adult patients enrolled at 28 U.S. sites and seven European sites, and 800 pediatric patients enrolled at nine U.S. children’s hospitals. 

The study, an analysis of cost drivers and formative research on an early consent approach, are informing resources to help you develop and streamline HABP/VABP clinical trial planning.  For example, patients at high risk for developing pneumonia could be approached and consented early, potentially before pneumonia symptoms develop so that fewer patients are excluded because they have already received 24 hours of effective antibacterial therapy.
