Clinical Trial Summary

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).

Intervention

Drug:
Acetaminophen Injection
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)
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)
Other:
Sodium chloride 0.9% injection
Placebo- IV q6h for 3 days
