Gram Negative Bacterial Infections

ClinConnect Summary

This clinical trial is studying two medicines, Aztreonam and Avibactam, to see how they work and how safe they are for children with serious bacterial infections caused by gram-negative bacteria. The trial is open to children aged 9 months to less than 18 years who are currently in the hospital and need intravenous (IV) antibiotics for complicated infections in areas like the abdomen, urinary tract, bloodstream, or lungs. If eligible, participants will receive either the new medicine combination (ATM-AVI) or the best available treatment.

During the study, participants will have some blood tests and may switch to oral medications after a few days, depending on their response to treatment. The total duration of the study for each participant will be between 33 to 50 days, including any follow-up calls to check on their health after treatment. It's important to know that certain conditions may exclude children from participating, such as specific infections that do not respond well to the medicines being tested or certain medical issues. The trial aims to provide valuable information about treating serious infections in children and is currently recruiting participants.
