A Phase 2/3 Open-label, Randomized, Active-controlled Clinical Study to Evaluate the Safety, Tolerability, Efficacy and Pharmacokinetics of MK-7655A in Pediatric Participants From Birth to Less Than 18 Years of Age With Confirmed or Suspected Gram-negative Bacterial Infection

Merck Sharp & Dohme LLC·interventional·Posted May 31, 2019·Updated Feb 5, 2026

In Brief

A Phase 3 clinical trial evaluating IMI/REL, Active Control, and 1 other intervention for Suspected or Documented Gram-negative Bacterial Infection. Completed, enrolled 115 participants across 67 sites in 18 countries.

Detailed 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.

Active Controldrug

All active control medications will be chosen from a list of acceptable approved agents for each infection type (HABP or VABP, cIAI, and UTI) and will be given via IV infusion, per authorized Package Insert (PI), Summary of Product Characteristics (SPC), or international treatment guidelines. NOTE: Participants with cIAI or cUTI may be switched to oral therapy after at least 3 days of IV study intervention. All oral switch medications will be chosen from a list of acceptable approved agents.

Oral Switchdrug

All oral switch medications will be investigator's choice from a list of acceptable approved agents for infection types cIAI, and cUTI and will be given per authorized Package Insert (PI), Summary of Product Characteristics (SPC), or international treatment guidelines. Participants with cIAI or cUTI may be switched to oral therapy after at least 3 days of IV study intervention.
