| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To investigate whether in preterm infants, born at a GA less than 28 completed weeks, with a PDA (diameter >1.5 mm) an expectative management is not inferior to early treatment with regard to the composite of mortality and/or NEC (Bell stage ≧ IIa) and/or BPD at a PMA of 36 weeks. |
|
| E.2.2 | Secondary objectives of the trial |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
- Gestational age < 28 completed weeks
- Postnatal age < 72 hours
- PDA diameter > 1.5 mm and ductal (predominantly) left-to-right shunt
- Signed informed consent obtained from parent(s) or representative(s)
|
|
| E.4 | Principal exclusion criteria |
- Contraindication for administration of cyclooxygenase-inhibitors (COXi)
- Use of COXi prior to randomization
- Persistent pulmonary hypertension (ductal right-to-left shunt ≧33% of cardiac cycle)
- Congenital heart defect, other than PDA and/or PFO
- Life-threatening congenital defects
- Chromosomal abnormalities and/or congenital anomalies associated with abnormal neurodevelopmental outcome |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
The primary endpoint is the composite of:
- Mortality at a postmenstrual age of ≤ 36 completed weeks, and/or
- NEC (Bell stage ≥ IIa) at a postmenstrual age of ≤ 36 completed weeks, and/or
- BPD, defined as the need for supplemental oxygen need at a postmenstrual age of 36 completed weeks |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| Postmenstrual age of 36 completed weeks |
|
| E.5.2 | Secondary end point(s) |
| Secondary endpoints are short term sequela of cardiovascular failure, adverse effects during the stay in the hospital and long term neurodevelopmental consequences assessed at a corrected age of 2 years. |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
- During the stay in hospital
- At a corrected age of 24 months |
