Trial Outcomes & Findings for A Phase 1/2 Study of Repeated Intravenous E6011 Administration in Japanese Subjects With Crohn's Disease (NCT NCT02039063)

NCT ID: NCT02039063

Last Updated: 2023-01-30

Results Overview

TEAEs was defined as adverse event (AEs) that emerged during the treatment, having been absent at pretreatment (Baseline) or re-emerged during treatment, having been present at pretreatment (Baseline) but stopped before treatment, or worsened in severity during treatment relative to the pretreatment state, when the AE was continuous. An AE was defined as any untoward medical occurrence in a participants or clinical study participant temporally associated with the use of study treatment, whether or not considered related to the study treatment. A SAE was defined as any untoward medical occurrence at any dose if it resulted in death or life-threatening AE or required inpatient hospitalization or prolongation of existing hospitalization or resulted in persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions or was a congenital anomaly/birth defect.
