E.1.1 | Medical condition(s) being investigated |
Prophylactic treatment of the ductus arteriosus in preterm infants |
|
E.1.1.1 | Medical condition in easily understood language |
The ductus arteriosus blood vessel allows blood to go around the baby's lungs before birth. If the vessel doesn't close after birth it is referred to as Patent DA and leads to abnormal blood flow. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary Objective
Phase II: The objective of Phase II is to define the minimum effective dose of acetaminophen to close the ductus arteriosus before or at day 7 in preterm infants of 23-26 weeks of gestation
Phase III: The primary objective is an increase in surviving without severe morbidity at 36 weeks of post menstrual age (or at discharge if it occurs before) from 50% (placebo group) to 60% in group receiving a prophylactic treatment by acetaminophen during the first 5 days of life. |
|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives
Phase II: a. Tolerance of acetaminophen at each dose b. Pharmacokinetics of acetaminophen and evaluation of the concentration-response curve (i.e., acetaminophen exposure vs. time to close the ductus arteriosus or decrease the size of ductus). c. To evaluate the relationship between acetaminophen concentration and toxicity occurrence.
Phase III: a. Early prophylactic treatment by acetaminophen decreases pain score and opiate consumption during the first 5 days of life. b. Early prophylactic treatment by acetaminophen reduces the number of back-up treatment of PDA (NSAIDs, surgery, trans-catheter procedure) c. Early prophylactic treatment by acetaminophen reduces catecholamines, opioid and parenteral nutrition requirements d. Pharmacokinetics of acetaminophen (in 50 preterms). |

E.3 | Principal inclusion criteria |
Study population
▪ The study population of the Phase II is constituted of 30 preterm infants of 23-26 weeks of gestational age (10 patients in 23-24 weeks of gestational age, 10 patients in 25 weeks of gestational age and 10 patients in 26 weeks of gestational age). ▪ The study population of the Phase III, is constituted of 396 preterm infants of 23-26 weeks of gestational age and of 398 preterm infants of 27-28 weeks of gestational age
Inclusion criteria ▪ Birth between 23-26 W for Phase II, between 23-28 W for Phase III ▪ Post natal age < 12 hours ▪ Parental or Legal Authority Consent ▪ Parents with a social security or health insurance (if applicable according to the local regulation)
|
|
E.4 | Principal exclusion criteria |
Non-inclusion criteria ▪ Parental refusal ▪ Birth defect / Congenital anomaly ▪ Twin-to-twin transfusion syndrome ▪ Suspicion of pulmonary hypoplasia ▪ Suspicion of hepatic impairment (hemorrhagic syndrome and/or severe hypoglycemia) ▪ Clinical instability that can lead to rapid death ▪ Impossibility to start treatment before 12 hours of life ▪ Parents placed under judicial protection ▪ Participation in other clinical trial using acetaminophen during the first 5 days of life, indomethacin or ibuprofen during the first 3 days of life or using rescue treatment of PDA not recommended in the TREOCAPA trial |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary study endpoint/outcome
Primary endpoint of phase II is the closure of Ductus Arteriosus (DA) assessed by echocardiography during the first 7 days of life, defined as DA closed at two consecutive echocardiographies or if the DA is closed at echocardiography of Day 7.
Primary endpoint of phase III is the survival without severe morbidity at 36 weeks of post menstrual age or at first discharge home, whichever comes first. The severe morbidities include bronchopulmonary dysplasia (BPD Grade 3 according to NIH consensus), necrotizing enterocolitis (NEC) of Bell's stage II or III, intraventricular hemorrhage (IVH) grade III-IV or cystic leukomalacia observed at any time up to 36 weeks of post menstrual age. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Phase II closure of Ductus Arteriosus (DA) assessed by echocardiography during the first 7 days of life, defined as DA closed at two consecutive echocardiographies or if the DA is closed at echocardiography of Day 7. Phase III Survival without severe morbidity at 36 weeks of post menstrual age or at first discharge home, whichever comes first. |
|
E.5.2 | Secondary end point(s) |
Phase II Main secondary endpoints of phase II are tolerance of acetaminophen. We will investigate: (1) Acetaminophen plasma levels (2) Plasma ALAT & ASAT (3) Prospective clinical monitoring (4) Adverse effects and concomitant drug exposures
Phase III Main secondary endpoints of phase III are: (1) Number of rescue treatment to close ductus by non steroid antiinflamatory drugs (NSAIDs) or by surgery or by transcatheter. (2) Diastolic systemic arterial pressure during the first week (3) Early and all Pulmonary hemorrhage (4) Cathecholamines, and opiate consumption during the first week of life (5) Volume of enteral nutrition during the first week of life (6) Interaction between parent involvement during the first week of life and medical care |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Phase II Monitoring of Adverse events will continue until discharge from the study at 36 weeks of post menstrual age or at first discharge home, whichever comes first, this is the maximum timepoint.
Phase III Monitoring of Adverse events including pulmonary hemorrage will continue until discharge from the study at 36 weeks of post menstrual age or at first discharge home, whichever comes first, this is the maximum timepoint. |
