Carbapenem Resistant Bacterial Infection Clinical Trial
Official title:
Cefiderocol and Ampicillin-sulbactam vs. Colistin or Colistin-meropenem for Carbapenem Resistant Acinetobacter Baumannii Bacteremia or Hospital-acquired Pneumonia: Controlled Clinical Study With Historical Controls (CASCADE)
Patients with bloodstream infections, hospital acquired pneumonia or ventilator-associated pneumonia caused by carbapenem-resistant Acinetobacter baumannii (CRAB) treated with cefiderocol combined with ampicillin sulbactam will be compared to patients treated treated with colistin alone or colistin combined with meropenem.
This will be a prospective controlled clinical study with historical controls. In the prospective CASCADE study consecutive consenting patients with bloodstream infections, hospital acquired pneumonia or ventilator-associated pneumonia will be treated with cefiderocol combined with ampicillin sulbactam in 3 hospitals in Israel and 2 hospitals in Italy, all endemic for CRAB. We plan to recruit 150 patients into this prospective studies. The CASCADE cohort will be compared to patients treated for the same types of infection in two recently completed randomized controlled trials (AIDA and OVERCOME). These trials compared between treatment with colistin vs. treatment with colistin-meropenem combination therapy, both finding no difference between treatment groups among patients with carbapenem-resistant Acinetobacter baumannii (CRAB) pneumonia. Thus, patients in CASCADE will be compared to all patients with CRAB bloodstream infections, hospital acquired pneumonia or ventilator-associated pneumonia in these randomized controlled trials. ;
