Tra i farmaci vietati si annoverano i corticosteroidi non in studio, lassativi e farmaci antidiarroici, nonché qualsiasi farmaco somministrato per via rettale (ad es. acido 5-aminosalicilico rettale [farmaco 5-ASA]); tuttavia, sono ammessi agenti 5-ASA orali a dosi pari a massimo 4,8 g al giorno e integratori di fibre giornalieri. I soggetti che assumono 5-ASA e/o agenti immunomodulanti verranno stratificati opportunamente. Sono vietati anche altri farmaci (ad es. antibiotici, farmaci antiepilettici e anticoagulanti). |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint is the proportion of subjects with clinical remission at the End of Treatment Visit (Visit 7). As shown in the table below, clinical remission is defined as the Modified Mayo Total Score of 0 to 2, with, stool frequency sub-score of 0 or 1 (minimum 1 point decrease from baseline), rectal bleeding sub-score of 0 and endoscopic sub-score of 0 or 1. |
L'endpoint primario è la percentuale di soggetti con remissione clinica alla Visita di fine trattamento (Visita 9). Come mostrato nella tabella seguente, la remissione clinica è definita come il punteggio Mayo totale modificato pari a 0-2, con un sottopunteggio della frequenza delle evacuazioni pari a 0 o 1 (diminuzione di almeno 1 punto dal basale), un sottopunteggio del sanguinamento rettale pari a 0 e un sottopunteggio endoscopico pari a 0 o 1. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |

E.5.2 | Secondary end point(s) |
Reduction of stool frequency defined as a reported score of 0 or 1, with at least a reduction of 1 point from baseline and absence of rectal bleeding (MMDAI sub-score of 0) defined as a reported score of 0. |
Riduzione della frequenza delle evacuazioni definita come un punteggio riportato di 0 o 1, con almeno una riduzione di 1 punto rispetto al basale e assenza di sanguinamento rettale (sottopunteggio MMDAI pari a 0) definita come un punteggio riportato pari a 0. |
