To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intravenous paracetamol at a loading dose of 20 mg/kg, followed by 7.5 mg/kg every 6 hours for 7 days. Paracetamol formulation that will be used is a commercially available product intended for parenteral administration (Perfalgan; Bristol- Myers Squibb, Munich, Germany), delivered in vials containing 50 ml of solution corresponding to 500 mg of paracetamol (10 mg of paracetamol in 1 ml of solution). If ductal closure evaluated by color-doppler ultrasound occurs before the seventh day of treatment, therapy will be discontinued.
Intervention code [1] 286560 0
Treatment: Drugs
Comparator / control treatment
Paracetamol at 15 mg/kg by oral route, every 6 hours for 7 days. Paracetamol formulation that will be used is a commercially available product intended for enteral administration (Tachipirina 100 mg/ml; Angelini, Rome, Italy), delivered in drops (3 mg of paracetamol in 1 drops), diluted in 2 ml of sterile water, administered via an orogastric tube, which will be flushed with further 1-2 mL of sterile water to ensure delivery of the drug into the stomach. If ductal closure evaluated by color-doppler ultrasound occurs before the seventh day of treatment, therapy will be discontinued.

Eligibility
Key inclusion criteria
Neonates with gestational age < 32 weeks and birth weight < 1500 g and with echocardiographic evidence of patent ductus arteriosus and contraindication to or failure of conventional medical therapy with COX inhibitors (ibuprofen or indomethacin) consecutively observed in Neonatal Intensive Care Unit are eligible for the trial. In all infants, color-doppler ultrasound will be performed at 24-48 hrs after birth to evaluate patency of ductus arteriosus and shunting. Elegibility of a neonate is defined by the presence at color-doppler ultrasound of at last one of the following criteria: 1. transductal diameter =/>1.5 mm, 2. reverse diastolic flow or absent diastolic flow in the descending aorta or in the superior mesenteric artery, anterior or middle cerebral arteries or renal artery, 3. unrestrictive pulsatile transductal flow (DA V max <2 m/s), 4. left-atrium-to-aortic-root ratio =/>1.5. Controindications to NSAIDs therapy are: reduced urine output (< 1 ml/kg/h) during the preceding 8 hours or other signs of renal failure, liver failure, intraventricular hemorrhage, a platelet count < 60,000/mm3, hyperbilirubinemia (defined as total bilirubin > 15 mg/dl), gastrointestinal bleeding and signs of feeding intolerance. Failure of NSAIDs treatment is defined by the presence of a patent ductus at the end of a single course of treatment with ibuprofen (loading dose at 10 mg/kg, followed by 5 mg/kg at 24 and 48 hours) or indomethacin (three doses at 0,2 mg/kg every 12 hours).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Enrolled neonates will be assigned to Group 1 (intravenous paracetamol) or to Group 2 (enteral paracetamol) according to a computerized and centralized randomization list. Each patient will be coded with a number reported in the randomization list. Researchers assessing ductal closure by echocardiographic examination will be unaware for study aims and group assignment. The data for the evaluation of treatment efficacy and safety will be recorded on data sheets especially designed for this study and labeled with the name of the enrolled neonate and with the randomization list code. Group assignment will be concealed until statistical analysis will be completed.

Statistical methods / analysis
The Kolmogorov-Smirnov test will be used to determine if variables are normally distributed. For continuous variables, groups will be compared using the test of equality of means, the Mann-Whitney test and Kruskal-Wallis test. The chi-square test and Fisher’s exact test will be used for categorical variables. For two related dichotomous variables, the McNemar test will be used to detect differences between study groups. We will perform a multivariate analysis (binary logistic regression) to evaluate whether PDA closure would be influenced by GA, modality of delivery, multiple birth, BW, sex, Apgar score at 5 minutes, or by study group assignment. The level of significance for all statistical tests is 2-sided, p<0.05. Statistical analysis will be performed, per intention-to-treat, by a statistician blinded to patient group assignment with SPSS Version 16.0 for Windows (SPSS Inc., Chicago, IL).
