Summary

This trial is studying the safety/effectiveness of ATM/AVI as a treatment for children with serious infections. They will be given an intravenous dose based on weight/kidney function, and may be switched to oral therapy.

Who is the study for?
This trial is for hospitalized children aged 9 months to less than 18 years with suspected or confirmed serious gram-negative infections, requiring IV antibiotics. It's not for those unlikely to respond to the study drugs within 14 days, pregnant/breastfeeding individuals without effective contraception, or those with certain medical conditions.
What is being tested?
The trial compares Aztreonam and Avibactam (ATM-AVI) combination against the best available therapy (BAT) in treating complicated infections like abdominal, urinary tract, bloodstream, and lung infections. ATM-AVI dosage depends on weight and kidney function; treatment lasts up to 14 days with possible switch to oral therapy.
What are the potential side effects?
Potential side effects may include reactions at the infusion site, allergic responses specific to antibiotic use such as rashes or gastrointestinal issues like nausea and diarrhea. Kidney function might be affected due to medication processing requirements.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: ATM-AVIExperimental Treatment1 Intervention
ATM-AVI administered iv every 6 or 8 hours and dosed according to participant's weight and kidney function for up to 14 days depending on response. At the investigator's discretion, the participant may be switched to oral therapy after 3 days of iv ATM-AVI therapy
Group II: Best available therapy (BAT)Active Control1 Intervention
BAT will be selected by the investigator and administered iv. At the investigator's discretion, the participant may be switched to oral therapy after 3 days of iv BAT
