Trial Information

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)

This study will enroll subjects who have been hospitalized at least three days (on or after
fourth day of hospital stay), 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) can reduce the risk of
colonization with antimicrobial-resistant bacteria or the isolation of a potential pathogen
compared to a standard antibiotic therapy (minimum of 8 days of therapy with antibiotics of
the primary care team's choosing). The study will also examine whether short-course therapy
reduces length of ICU and hospital LOS and costs based on ICU and hospital LOS, antibiotic
treatment, and standardized costs related to the treatment of infection-related adverse
experiences, without having a negative effect on subject mortality or the incidence of
clinically significant infection.

Inclusion Criteria

6. Suspected or proven extrapulmonary infection site requiring antibiotic therapy.

7. History of anaphylaxis to penicillin or cephalosporins.

carbapenems (e.g., imipenem).

9. On systemic antibiotics for more than 7 consecutive days during the previous 30 days.

10. Received more than two doses of systemic antibiotics within the past 24 hours (other
than those used for surgical prophylaxis).

urine pregnancy test within the 7 days prior to the first dose of antibiotics.)

12. On mechanical ventilation for > 7 consecutive days during the previous 30 days.
