E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This study is exploratory in nature and will investigate safety and tolerability of an oral liquid formulation of dabigatran etexilate in pediatric patients 1 to < 12 years old treated for primary VTE. The study will also provide preliminary pharmacokinetic and pharmacodynamic data for this age group. |
Questo studio e' di natura esplorativa e indaghera' la sicurezza e la tollerabilita' di una formulazione orale in liquido di dabigatran etexilato in successivi gruppi di pazienti pediatrici di eta' compresa tra 2 e < 12 anni seguiti da 1 a < 2 anni trattati per tromboembolismo venoso. Lo studio fornira' anche i dati preliminari di farmacocinatica e farmacodinamica per questa fascia di eta' |
