Ventilator Associated Pneumonia Clinical Trial

Official title: EaRly impAct theraPy With Ceftazidime-avibactam Via rapID Diagnostics Versus Standard of Care Antibiotics and Diagnostics in Patients With Bloodstream Infection, Hospital-acquired Pneumonia or Ventilator-associated Pneumonia Due to Pseudomonas Aeruginosa or Carbapenemase Producing Enterobacterales (RAPID)

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to propose a seamless intervention linking rapid bacterial isolate identification and antibiotic resistance gene detection and targeted antibiotic prescription to minimise time between infection onset and appropriate treatment in patients with Pseudomonas aeruginosa or carbapenemase producing Enterobacterales infections. This is an investigator initiated trial. The primary hypothesis is that these interventions will lead to improved clinical outcomes amongst patients with hospital-acquired bloodstream infection, hospital-acquired pneumonia or ventilator-associated pneumonia due to carbapenem non-susceptible Pseudomonas aeruginosa or Enterobacterales, compared to standard antibiotic susceptibility testing. Patients will be randomised to either a control or intervention arm. Patients randomised to the intervention arm will have relevant specimens analysed by rapid microbiological diagnostics and will have early availability of ceftazidime-avibactam if appropriate. Patients randomised to the control arm, will have samples analysed by clinical microbiology laboratories using standard of care diagnostics. Antibiotics will be available to these patients as per usual institutional practice.

Clinical Trial Description

This is an open-label, multinational, randomised, superiority trial. Patients will be randomised to control and intervention arms. Patients randomised to the intervention arm, will have the BioFire Blood Culture Identification 2 Panel (BCID2) used for positive blood cultures and/or the BioFire FilmArray Pneumonia or Pneumonia plus Panel for respiratory tract specimens if having hospital-acquired pneumonia or ventilator-associated pneumonia. Standard of care diagnostics will also be used. Antibiotic guidelines will be provided to clinicians to aid interpretation of test results and treatment prescription. Ceftazidime-avibactam will be available for targeted use in patients with Pseudomonas aeruginosa or carbapenemase producing Enterobacterales. Patients randomised to the control arm, will have samples analysed by clinical microbiology laboratories using standard of care diagnostics. Antibiotics will be available to these patients as per usual institutional practice. The main population that will be recruited in the study will be hospitalised patients with bloodstream infections, hospital-acquired pneumonia or ventilator-associated pneumonia due to Pseudomonas aeruginosa or carbapenemase producing Enterobacterales treated with ceftazidime-avibactam, while the secondary population recruited will be those with multidrug resistant (MDR) Gram-negative bacilli. The enrolment criteria are based on the US Centers for Disease Control and Prevention criteria for healthcare-associated infection surveillance. Clinical and mortality outcomes will be assessed for 60 days post infection. The infection causing bacterial isolates will be collected for genotypic description via whole genome sequencing. The total target sample size is 1900 participants in the main population over 20 study sites. ;
