Clinical Trial Summary

The primary purpose of this study is to evaluate the safety and tolerability of imipenem/cilastatin/relebactam (IMI/REL) in participants from birth to less than 18 years of age with confirmed or suspected gram-negative bacterial infection. Participants are expected to require hospitalization through completion of intravenous (IV) study intervention, and have at least one of the following primary infection types: hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP); complicated intra-abdominal infection (cIAI); or complicated urinary tract infection (cUTI). Participants will be randomized in a 3:1 ratio to receive IMI/REL or active control. This study will also evaluate the efficacy of IMI/REL by assessing all-cause mortality at Day 28 post-randomization, as well as clinical and microbiological response to treatment. It will also evaluate the pharmacokinetics of IMI/REL.
