| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objective of this study is to assess the efficacy of prasugrel compared to placebo in pediatric patients with SCD as measured by reduction in the rate of VOC, which is a composite endpoint of painful crisis or acute chest syndrome, throughout the study. |
| L'obiettivo primario di questo studio è la valutazione dell'efficacia di prasugrel rispetto al placebo in pazienti pediatrici affetti da malattia a cellule falciformi (SCD), misurata in termini di riduzione del tasso di crisi vaso-occlusive (VOC) che rappresenta un endpoint composito di crisi di dolore o sindrome toracica acuta, per tutto lo studio. |
|
| E.2.2 | Secondary objectives of the trial |
Major Secondary Efficacy Objectives
• Assess the efficacy of prasugrel compared to placebo in pediatric patients with SCD by assessment of the following key endpoints:
1. the reduction in the rate and intensity of sickle cell-related pain as recorded in patient pain diaries
2. the reduction in the rate of hospitalization for VOC
Safety Objectives:
• Assess the safety of prasugrel compared to placebo in pediatric patients with SCD. |
•Determinare l'efficacia di prasugrel rispetto al placebo in pazienti pediatrici affetti da SCD mediante la valutazione dei seguenti endpoint in una procedura di gatekeeping a sequenza fissa:
1.riduzione del tasso di dolore correlato alla malattia a cellule falciformi, secondo quanto registrato nei diari del dolore del paziente
2.riduzione del tasso di ricoveri per VOC
malattia a cellule falciformi, secondo quanto registrato nei diari del dolore del paziente
Obiettivi di sicurezza:
• Valutare la sicurezza di prasugrel rispetto al placebo in pazienti pediatrici con malattia a cellule falciformi. |
