A Phase 1 interventional study of Paracetamol 10Mg/mL and 0.45% Sodium Chloride in Patent Ductus Arteriosus, sponsored by University of Oulu. Terminated at 4 sites in Finland. Open to participants aged Up to 4 Months. Per ClinicalTrials.gov, last updated 2024-10-18.

Why this study was terminated
The PDA patients have vanished. The last recruitment took place in 2022. In the joint discussion of the principal researchers, it was concluded that PDA patients no longer have to be treated in Finland and the study was terminated.

Study summary

The purpose of this pilot trial is to study efficacy and safety of simultaneous intravenous (iv) ibuprofen/indomethacin and paracetamol medications in the closure of patent ductus arteriosus (PDA) in preterm infants. It is randomized, placebo-controlled, double-blind, phase 1, multicenter, clinical trial.

Read the detailed description

Premature infants (born before 37 weeks gestational age) with patent ductus arteriosus (PDA) are the focus of the study since no trials on the additive efficacy of these two medications on the contraction of ductus arteriosus are available. Preterm infants who are diagnosed to have a hemodynamically significant PDA and who, according to the decision of the attending clinician, need ibuprofen/indomethacin therapy, are eligible to this trial.

If the parents deny the consent, the patient will be treated according to the standard PDA treatment: three days' iv ibuprofen Pedea® 5mg/ml solution infusion (Oulu, Helsinki, Tartu) dosing: 10mg/kg + 5mg/kg + 5mg/kg (q24h); or three days' iv indomethacin (Turku) 0.2mg/kg + 0.1mg/kg + 0.1mg/kg (q24h). In case of any contraindications for ibuprofen/indomethacin, the treatment would be surgical ligation.
