E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objective is the study of efficacy during therapy with oral viscous budesonide, through evaluation of histological features ofesophageal mucosa before and after 3 months of therapy, in a group of patients between 1 month and 18 years old affected by EA with concomitant EoE. Intramucosal eosinophils < 15 eosinophils/HPF at the end of the therapeutic cycle will determine the efficacyof budesonide. |
L’obiettivo primario è lo studio dell’efficacia della terapia con budesonide viscosa assunta per via orale, attraverso la valutazione delle caratteristiche istologiche della mucosa esofagea prima e dopo tre mesi di terapia, in un gruppo dei pazienti di età compresa tra 1 mese e 18 anni affetti da AE (corretta chirurgicamente mediante anastomosi diretta esofago-esofagea) con concomitante EoE (diagnosi istologica:> 15 eosinofili/HPF in biopsie esofagee prossimali e distali). L’assenza di flogosi (eosinofili intramucosali < 15 eosinofili/HPF) al termine del ciclo terapeutico sarà segno di efficacia terapeutica del farmaco. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are clinical efficacy and safety evaluation after 3 months of therapy and after 3 months of follow-up, through assessment of clinical signs of esophagealstricture, number of relapses and quality of life of patients (dysphagia score) and adverse reactions to budesonide. The study will also assess the Pharmacokinetics (PK) of budesonide. |
Obiettivi secondari saranno l’efficacia clinica e la sicurezza dopo tre mesi di terapia, e dopo tre mesi di follow-up, attraverso la valutazione dei segni clinici di stenosi dell’esofago, del numero di recidive cliniche e della qualità di vita dei pazienti (score clinico disfagia), e del numero delle reazioni avverse al farmaco. Lo studio valuterà anche il profilo farmacocinetico del farmaco (PK). |
