E.2 Objective of the trial

E.2.1

Main objective of the trial

The primary objective of Part A is to determine the cadazolid dose in children from birth to < 18 years of age by investigating the safety, efficacy, and the systemic and fecal pharmacokinetics (PK).
The primary objective of Part B is to assess the safety and efficacy of cadazolid in children from birth to < 18 years of age as compared with vancomycin.

L’obiettivo primario della Parte A è determinare la dose di cadazolid nei bambini dalla nascita a < 18 anni di età analizzando la sicurezza, l’efficacia e la farmacocinetica (Pharmacokinetics, PK) sistemica e fecale.
L’obiettivo primario della Parte B è valutare la sicurezza e l’efficacia di cadazolid nei bambini dalla nascita a < 18 anni di età rispetto alla vancomicina.

E.2.2

Secondary objectives of the trial

Secondary objectives of Part A are to assess the efficacy of cadazolid in terms of Clinical Cure, Sustained Clinical Cure, and Recurrence.
Secondary objectives of Part B are to assess the efficacy of cadazolid in terms of Sustained Clinical Cure, Recurrence, time to Recurrence, and time to resolution of diarrhea (ROD) as compared to vancomycin.

Gli obiettivi secondari della Parte A sono valutare l’efficacia di cadazolid in termini di guarigione clinica, guarigione clinica sostenuta e recidiva.
Gli obiettivi secondari della Parte B sono valutare l’efficacia di cadazolid in termini di guarigione clinica sostenuta, recidiva, tempo alla recidiva e tempo alla risoluzione della diarrea (Resolution Of Diarrhea, ROD) rispetto alla vancomicina.
