| E.1 Medical condition or disease under investigation | 
| E.1.1 | Medical condition(s) being investigated | 
| Patent ductus arteriosus of a premature infant |  
| Avoin valtimotiehyt |  | 
| E.1.1.1 | Medical condition in easily understood language | 
| Patent ductus arteriosus of a premature infant |  
| Avoin valtimotiehyt |  | 
| E.1.1.2 | Therapeutic area | Diseases [C] - Congenital, Hereditary, and Neonatal Diseases and Abnormalities [C16] | 
| MedDRA Classification | 
| E.1.3 | Condition being studied is a rare disease | No | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To evaluate the effect and safety of intravenous paracetamol when combining with ibuprofen/indomethacin therapy for patent ductus arteriosus |  
| Tämän tutkimuksen tarkoituksena on selvittää parasetamolin ja ibuprofeenin/indometasiinin yhteisvaikutusta ja turvallisuutta avoimen duktuksen sulkemisessa pienillä keskosilla. |  | 
| E.2.2 | Secondary objectives of the trial |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| - premature infants - treated in the neonatal intensive care units of the attending sites
 - diagnosed to have a hemodynamically significant patent ductus arteriosus
 - intravenous ibuprofen or indomethacin medication
 |  
| Tutkimukseen otetaan mukaan tutkimuskeskusten vastasyntyneiden teho-osastoilla hoidettavia keskosia, joille aloitetaan hoitavan lääkärin päätöksellä hemodynaamisesti merkitsevän valtimiotiehyen vuoksi suonensisäinen ibuprofeeni- tai indometsiinihoito. |  | 
| E.4 | Principal exclusion criteria | 
| - no parental consent - any congenital or chromosomal anomaly or severe clinical situation that complicates the conventional ductal therapy, e.g. severe asphyxia or persistent pulmonary hypertension of a newborn
 |  
| Tutkimuksen poissulkukriteereitä ovat vanhempien kieltäytyminen, vaikea rakenne- tai kromosomipoikkeavuus tai muu vaikea kliininen tilanne, joka vaikeuttaa olennaisesti pienen keskosen tavanomaista duktushoitoa, esimerkiksi vaikea asfyksia tai koholla oleva keuhkoverenpaine (PPHN). Sydämen ultraäänitutkimuksessa potilaalla voi olla alle 3 mm kokoinen kammioväliseinäaukko, mutta tätä vaikeammat sydämen rakennepoikkeavuudet ovat poissulkukriteereitä. |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Ductal closure |  
| Duktuksen sulkeutuminen |  | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| - after the study drug period - discharge from neonatal intensive care unit
 |  
| - tutkimuslääkkeen jälkeen - poistuessa vastasyntyneiden teholta
 |  | 
| E.5.2 | Secondary end point(s) | 
| - further ductal therapies - neonatal morbidity and mortality: IVH, NEC, BPD, ROP
 |  
| - muut duktushoidot - myöhäisempi vastasyntyneen sairastavuus ja kuolleisuus
 |  | 
| E.5.2.1 | Timepoint(s) of evaluation of this end point | 
| - discharge from hospital |  
| - kotiuminen |  |
