Number of Participants With Treatment-emergent Adverse Events (TEAEs)
Number of participants with TEAEs were reported. An adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. Treatment-emergent AEs (TEAEs) were AEs with onset during the intervention phase or that were a consequence of a pre-existing condition that had worsened since baseline. All TEAEs including serious and non-serious AEs were reported.

Number of participants with TESAEs were reported. TEAEs are AEs with onset during the intervention phase or that are a consequence of a pre-existing condition that had worsened since baseline. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Time frame: From baseline (Week 0) up to Week 48
Number of Participants With Treatment-emergent Adverse Events of Special Interest (TEAESI)

The C-SSRS was an investigator-administered questionnaire: 1) No suicidal ideation or behaviors (including self-injurious behavior without suicidal intent): No further action was needed; 2) Suicidal ideation levels 1-3 or non-suicidal self-injurious behavior; participant risk is assessed by the investigator. 3) Suicidal ideation levels 4 or 5 or any suicidal behavior: participant risk assessed and referral to a mental health professional. If no events qualify for scores of 1 to 10, score of 0 was assigned (0= "no event that can be assessed on the basis of C-SSRS"). Higher scores indicated greater severity.

Each endoscopic component was scored from 0 (best) to 3 (worst) for each segment, resulting in a total score of up to 15 for each component, except for the narrowing component which only attain a maximum total score of 11 because, the presence of a narrowing that cannot be passed can be only observed once. The total SES-CD score was the sum of all the component scores across all the segments and it ranged from 0 (best) to 56 (worst), where higher scores indicated more severe disease.
