About this study
Official title: Randomized, Multi-Center, Comparative Trial of Short-Course Empiric Antibiotic Therapy Versus Standard Antibiotic Therapy for Subjects With Pulmonary Infiltrates in the Intensive Care Unit (ICU): Impact on Antimicrobial Resistance, Superinfections, Length of ICU Stay and Hospitalization, and Mortality
This study will enroll 460 subjects who have new pulmonary infiltrates during their ICU stay and who are at low risk of having pneumonia, as determined using the Clinical Pulmonary Infection Score (CPIS). The study is designed to determine whether 3 days of antibiotic treatment with meropenem (with or without coverage for MRSA) for ICU subjects diagnosed with new pulmonary infiltrates can reduce the emergence of anti-microbial-resistant organisms and the isolation of a potential pathogen compared to a standard course of antibiotic therapy (minimum of 8 days of therapy with antibiotics of the primary care team's choosing). Subjects will be randomly placed in either the meropenem group or standard antibiotic therapy group. The study will also examine whether short-course therapy reduces hospital length of stay and hospital cost, without having a negative effect on subject morbidity and mortality.
Read the detailed description
Intensive care units (ICUs) are the most frequently identified source of nosocomial infections within the hospital, with infection rates and antimicrobial resistance rates significantly higher than in the general ward. In one study, antimicrobial use was reported to be 10 times higher in the ICU compared to antimicrobial use in the general ward. Although antibiotics are given for a variety of conditions, antibiotics prescribed for respiratory infections, suspected or proven, account for almost one-half of all antibiotic consumption in the ICU. Importantly, the use of antimicrobial agents has been identified as a critical risk factor in the emergence of resistant bacterial infections. By identifying and focusing on subsets of subjects who are unlikely to have infection and therefore unlikely to benefit from antibiotics, antibiotic use and the subsequent emergence of antimicrobial-resistant organisms could be limited. This is a Phase III, multi-center, randomized, open-label study designed to determine whether 3 days of antibiotic treatment with meropenem (with or without coverage for MRSA) for ICU subjects diagnosed with new pulmonary infiltrates can reduce the emergence of antimicrobial-resistant organisms and the isolation of a potential pathogen compared to a standard course of antibiotic therapy (minimum of 8 days of therapy with antibiotics of the primary care team's choosing). The primary objective of this study is to compare risk of resistant infection in the ICU by evaluating the difference in the incidence of either the emergence of antimicrobial-resistant bacteria or the isolation of a potential pathogen in ICU subjects who receive short-course empiric antibiotic therapy to ICU subjects who receive standard antibiotic therapy for the treatment of pulmonary infiltrates (with low likelihood of having pneumonia). Secondary objectives are to: 1) assess the mortality of subjects receiving short-course empiric antibiotic therapy compared to standard antibiotic therapy; 2) assess the ICU length of stay (LOS) in subjects receiving short-course empiric antibiotic therapy compared to standard antibiotic therapy; 3) assess the hospital LOS in subjects receiving short-course empiric antibiotic therapy compared to standard antibiotic therapy; 4) assess the costs of antibiotic therapy in subjects receiving short-course empiric antibiotic therapy compared to standard antibiotic therapy. The costs will be based on ICU LOS, hospital LOS, antibiotic treatment, and standard costs related to the treatment of infection-related adverse experiences; 5) assess the risk of clinically significant infection in subjects receiving short-course empiric antibiotic therapy compared to standard antibiotic therapy. This study will enroll 460 subjects who have new pulmonary infiltrates during their ICU stay and who are at low risk of having pneumonia, as determined using the Clinical Pulmonary Infection Score (CPIS).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Meropenem and Standard antibiotic therapy in people with Bacterial Infection, run by National Institute of Allergy and Infectious Diseases (NIAID) at 10 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 7 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Combined measure of either emergence of antimicrobial resistance or isolation of a potential pathogen detected in any positive clinical cultures that are deemed a clinically significant infection (time frame: Day 0 to day 28 (or hospital discharge, if earlier)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jun 2013; AzTrials last refreshed its copy on 8 Nov 2026.
