E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to evaluate with a randomized, placebo-controlled trial the efficacy of thyroxine supplementation in the first weeks of life in term of psychomotor development and mental outcome at 24 months of corrected age in preterm infants with gestational age at or less 28 weeks |
Valutare mediante studio randomizzato, controllato con placebo, l’efficacia della somministrazione di L-Tiroxina nelle prime settimane di vita sullo sviluppo psicomotorio e mentale all’eta' di 24 mesi di eta' gestazionale corretta in neonati pretermine di eta' gestazionale inferiore/uguale a 28 settimane |
|
E.2.2 | Secondary objectives of the trial |
1) to evaluate the safety/tolerability of the experimental treatment 2) to evaluate on the selected population the effects of the therapy on thyroid hormone levels, on mortality and morbidity , on psychomotor and mental developmental at 6 and 12 months of corrected age 3) to evaluate the possible influence of gestational age, initial level of fT4, gender, intercurrent illness and iatrogenic effects on the therapeutic effectiveness of L-thyroxine |
1) Valutare la sicurazza/tollerabilita' del trattamento sperimentale 2) Valutare nella popolazione selezionata gli effetti del trattamento sui livelli sierici di ormoni tiroidei, sulla morbilita' e mortalita' nel periodo dello studio e sullo sviluppo psicomotorio e mentale a 6 e 12 mesi di eta' gestazionale corretta 3) Valutare l’eventuale impatto dei fattori eta' gestazionale, livelli iniziali di f-T4, sesso, malattie intercorrenti ed effetti iatrogeni sull’efficacia terapeutica della L-Tiroxina |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) gestational age at or less 28 weeks 2) postnatal serum fT4 levels below a cutoff value of appropriate ranges of cord levels corrected to an equivalent gestational age and TSH values less than 10 mU/L 3) obtained signed informed consent |
1) EG ≤ 28 settimane 2) Livelli sierici postnatali di fT4 determinati tra 48 e 72 ore di vita inferiori ad una soglia appropriata per l’eta' gestazionale e livelli sierici di TSH < 10 mU/L. 3) Consenso informato scritto ottenuto da entrambi i genitori o dal rappresentante legale del minore |
|
E.4 | Principal exclusion criteria |
1) known or suspected hyperergia to the drug 2) severe congenital malformations or clinical conditions that contraindicate the participation in the trial 3) known adrenal insufficiency 4) maternal thyroid disease or illicit-drug use by the mother |
1) Nota o sospetta ipersensibilita' al farmaco o alla classe farmacologica in studio 2) Gravi malformazioni congenite o gravi condizioni cliniche che, a giudizio dello sperimentatore, controindicano la partecipazione del paziente allo studio 3) Insufficienza surrenalica 4) Malattie tiroidee o uso di droghe nella madre |
|
E.5 End points |
E.5.1 | Primary end point(s) |
