Polymyxin B Monotherapy vs Combination Therapy in Critically Ill Patients

Status Recruiting

Clinical Trial Summary

The purpose of this study is to assess the safety and efficacy of polymyxin B as monotherapy versus a combined polymyxin B-carbapenem therapy against multidrug-resistant (MDR) gram negative infections. The investigators intend to evaluate if this synergistic drug regimen correlates with improved outcomes against gram-negative infections in critically ill patients including: better clinical resolution, reduced length of stay at hospital, reduced length of stay at the intensive care unit, and less recurrence of infection.

Clinical Trial Description

The "MUSEUM" trial is a single-center, prospective, parallel-group, double-blind, randomized, controlled study design. The trial will be conducted at the Intensive Care Unit of the Puerto Rico Trauma Hospital located in San Juan, Puerto Rico. Patients with clinical and microbiological evidence of an Multi-drug resistant infection related to Hospital-acquired pneumonia (HAP), Ventilator-associated pneumonia (VAP), Complicated Urinary tract infection (cUTI) or Bloodstream infection (BSI) will be considered candidates for the study. The pathogen should be resistant to all antibiotics except to polymyxin B. With a predicted survival rate of 67% (hazard ratio of 0.33), a significance of α = 0.05, power of 80%, and assuming a dropout rate of 15%, the estimated sample size is n = 40 patients (20 per group). In terms of safety, the most clinically relevant adverse effects are nephrotoxicity and neurotoxicity, which will be evaluated and adjudicated. The recurrence of infection will be defined as a new superinfection by the same or other species than the initial infection that is multidrug-resistant. Length of stay at the Hospital will be measured from the day of admission until the day of discharge. Length of stay in the ICU will be measured from the day of admission until the day of discharge from the unit. To our knowledge, this will be the first prospective, double blind, randomized, controlled clinical trial in representation of the critically ill trauma patients infected with Multi-drug resistant pathogens. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
