Indomethacin PK-PD in Extremely Preterm Neonates

Phase 2
Withdrawn
Conditions
Patent Ductus Arteriosus After Premature Birth
Interventions
Registration Number
NCT04025177
Lead Sponsor
University of Manitoba
Brief Summary

This is a phase II open-label study evaluating the pharmacokinetics and pharmacodynamics of targeted early use of indomethacin for PDA treatment in preterm neonates \<27 weeks' gestational age.

Detailed Description

Neonates will be enrolled following an echocardiogram performed within 12 hours after birth that confirms an open PDA (with no other contraindications for indomethacin treatment). After enrollment, neonates will receive intravenous indomethacin at a dose of 0.1mg/kg every 24 hours for 3 days. Indomethacin levels will be measured at regular intervals. Urine output and serum electrolytes will be monitored prior to each dose of indomethacin. An echocardiogram will be repeated after completion of indomethacin treatment (between 72-120 hours of age) to reassess the status of PDA.
