An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be reported.
An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study treatment due to an AE will be reported.
Number of participants who experienced treatment-emergent adverse events (AEs)
Number of participants who experienced serious adverse events (SAEs)
Number of participants who experienced AEs leading to discontinuation
Number of participants achieving induction of endoscopic improvement (decrease in simple endoscopy score for Crohn's disease \[SES-CD\] ≥ 50% from Baseline)
