Carbapenem

Piperacillin/Tazobactam vs Meropenem for Bacterial Blood Infections (PETERPEN Trial)

Phase 4
Recruiting
Led By Roni Bitterman, MD
Research Sponsored by Rambam Health Care Campus
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
The microorganism will have to be non-susceptible to third generation cephalosporins (ceftriaxone and ceftazidime) and susceptible to both PTZ and meropenem (see microbiological methods)
Both community and hospital-acquired bacteremias will be included
Must not have
Patients with septic shock at the time of enrollment and randomization, defined as at least 2 measurements of systolic blood pressure < 90 mmHg and/or use of vasopressors (dopamine>15μg/kg/min, adrenalin>0.1μg/kg/min, noradrenalin>0.1μg/kg/min, vasopressin any dose) in the 12 hours prior to randomization. In the absence of the use of vasopressors, a systolic blood pressure <90 would need to represent a deviation for the patient's known normal blood pressure
Patients with prior bacteremia or infection that have not completed antimicrobial therapy for the previous infectious episode
Timeline
Screening 3 weeks
Treatment Varies

Summary

This trial is testing whether piperacillin-tazobactam is as good as meropenem for treating blood-stream infections caused by bacteria that are resistant to cephalosporins.

Who is the study for?
Adults over 18 with bloodstream infections caused by specific bacteria (E. coli or Klebsiella spp.) resistant to certain antibiotics but susceptible to Piperacillin/tazobactam and Meropenem can join. Excluded are those with septic shock, polymicrobial bacteremia, certain severe infections like endocarditis, allergies to study drugs, previous trial participation, or other clinical trials.
What is being tested?
The PETERPEN trial is testing whether Piperacillin/tazobactam is as effective as Meropenem in treating bloodstream infections from cephalosporin-resistant Enterobacteriaceae. It's a head-to-head comparison of these two antibiotic treatments.
What are the potential side effects?
Possible side effects include allergic reactions, gastrointestinal issues like nausea and diarrhea, headache, skin rash or itching. Both antibiotics may also affect liver enzymes and white blood cell counts.
