Indomethacin PK-PD in Extremely Preterm Neonates
- 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.

Group Intervention Description Neonates with an open PDA Indomethacin Injection Neonates born between 23 (0/7) and 26 (6/7) weeks gestational age with an open PDA, according to clinical protocol criteria, and no contraindication to the use of indomethacin.
- Primary Outcome Measures
Name Time Method Area under the curve from serial Indomethacin levels At 48 hour following the last dose Blood samples will be drawn from patients to determine the serum indomethacin levels to determine the area under the curve
- Secondary Outcome Measures
Name Time Method Percentage of Participants with Intraventricular hemorrhage Within the first 7 days of life. Confirmed by cranial ultrasound performed and graded using Papile's classification system
Percentage of Participants with Adverse Events trough hospital discharge, an average of up to 36 weeks gestational age development of any type A adverse reactions in the infants receiving indomethacin therapy
Percentage of Participants with Patent Ductus Arteriosus Closure Within 48 hrs after the last dose Confirmed by echocardiogram
Duration of mechanical ventilation of each patient trough hospital discharge, an average of up to 36 weeks gestational age Number of days the infant was intubated and ventilated.
