About this trial

Patent ductus arteriosus (PDA), the most common cardiovascular complication of prematurity, is associated with higher mortality and morbidities in extremely low gestational age neonates (ELGANs, \< 27+0 weeks). Ibuprofen and acetaminophen, which act by reducing prostaglandin synthesis, are the most commonly used first and second line agents for PDA treatment across Canada. However, initial treatment failure with monotherapy is a major problem, occurring in \>60% ELGANs. Treatment failure is associated with worsening rates of mortality and bronchopulmonary dysplasia (BPD), while early treatment success can achieve rates comparable to neonates without PDA. Treatment failure resulting in prolonged disease exposure is thought to be a major contributor. Recently, combination therapy with acetaminophen and ibuprofen has emerged as a new treatment regime. Acetaminophen exerts anti-prostaglandin effect through a different receptor site than ibuprofen, providing a biological rationale for their synergistic action.

The objective of this study is to evaluate the clinical impact, efficacy and safety of combination regime (Ibuprofen + IV Acetaminophen) for the first treatment course for PDA in ELGANs vs. Ibuprofen alone (current standard treatment).

The study will also evaluate the effects of combination regime vs. ibuprofen alone on neurodevelopmental outcomes at 18-30 months corrected age.

Treatments tested in this trial

  • Acetaminophen Injection

    Drug

    Acetaminophen injection solution 1000 mg/100 mL (10 mg/mL) latex-free plastic bag - dosage for this protocol is 15mg/kg/dose IV four times a day for 3 days

  • Ibuprofen 20 mg/mL oral suspension or Ibuprofen lysine 10 mg/mL injection solution (Neoprofen)

    Drug

    Ibuprofen is not a study drug - standard of care in participating NICUs in the standard clinical dose for neonates (typically, for neonates \< 7 days old - 10 mg/kg/dose on day 1, 5 mg/kg/dose q24h on days 2 and 3; for neonates \> 7 days old - 20 mg/kg/dose on day 1, 10 mg/kg/dose q24h on days 2 and 3)

  • Sodium chloride 0.9% injection

    Other intervention

    Placebo- IV q6h for 3 days
