Evaluation of Pharmacokinetics, Safety, and Tolerability of Ceftazidime-avibactam in Neonates and Infants. — NOOR  

Gram-negative Bacterial Infection Clinical Trial

Official title: A PHASE 2A, 2-PART, OPEN-LABEL, NON-RANDOMIZED, MULTICENTER, SINGLE AND MULTIPLE DOSE TRIAL TO EVALUATE PHARMACOKINETICS, SAFETY AND TOLERABILITY OF CEFTAZIDIME AND AVIBACTAM IN NEONATES AND INFANTS FROM BIRTH TO LESS THAN 3 MONTHS OF AGE WITH SUSPECTED OR CONFIRMED INFECTIONS DUE TO GRAM-NEGATIVE PATHOGENS REQUIRING INTRAVENOUS ANTIBIOTIC TREATMENT

Status Terminated

Clinical Trial Summary

This study will assess the pharmacokinetics, safety, and tolerability of single and multiple doses of intravenous ceftazidime-avibactam in hospitalized infants and neonates from 26 weeks gestation to 3 months of age. In Part A of the study all patients will receive a single dose of ceftazidime-avibactam. In Part B all patients will received multiple doses of ceftazidime-avibactam. Efficacy will be assessed in the infants and neonates receiving multiple doses of ceftazidime-avibactam.

Clinical Trial Description

This is a 2-part, Phase 2a, non-randomized, open-label multicenter, multinational study of intravenous ceftazidime-avibactam in hospitalized neonates and infants with suspected or confirmed bacterial infection. In Part A of the study, patients already receiving intravenous antibacterial therapy with another antibiotic will receive a single intravenous dose of ceftazidime-avibactam followed by observation for 48 hours and a Late Follow-Up assessment 4-5 weeks later. In Part B of the study, patients with suspected or confirmed Gram-negative bacterial infections requiring intravenous antibacterial therapy will receive multiple doses of intravenous ceftazidime-avibactam for up to 14 days. At the discretion of the investigator, patients may also receive other antibiotics if the infection is suspected to include Gram-positive bacteria, multi-drug resistant Gram-negative bacteria, or anaerobic bacteria. At the discretion of the investigator, patients may be switched to oral therapy or outpatient parenteral antimicrobial therapy with an alternative antibiotic after receiving intravenous ceftazidime-avibactam for at least 48 yhours. Clinical outcomes will be assessed at the End of Intravenous (EOIV) treatment with ceftazidime-avibactam, the End-of-Therapy (EOT), the Test-of-Cure (TOC) at 7-14 days after the last study therapy and at a Late Follow-Up (LFU) visit, 28-55 days after the last dose of ceftazidime-avibactam. Safety assessments will occur throughout the study. Ceftazidime-avibactam blood levels will be assessed during the first 12 hours after the single dose of ceftazidime-avibactam in Part A and during 12 hours after at least 3 consecutive doses of ceftazidime-avibactam in Part B. ;
