Participant Flow

A total of 8 participants were enrolled in this present study.

For secondary pharmacokinetic (PK) outcome measures' analysis, as planned, data of participants who received Etrasimod 2 mg IR tablet (Treatment A) in C5041034 study \[NCT05956002\] is used for comparison. These participants were not enrolled in the present study C5041050 \[NCT06140290\], only the relevant historical data was used for comparison as per the objectives.

Timeframe: Baseline; Anytime or latest time with minimum HR measurement taken post-dose on Day 1 of each period

Population: SAS included all participants who took at least 1 dose of study intervention.

Heart rate was measured in beats per minute (beats/min). Baseline was defined as the average of triplicate ECG HR measurements collected at pre-dose (0 hour) on Day 1 of each period. Nadir HR was taken as the minimum HR from all ECGs taken post-Etrasimod on day 1 of each period. If Nadir HR was attained at multiple post-dose time points on Day 1, only the latest time point was summarized.

SECONDARY outcome

Timeframe: Day 1 up to 35 days after last dose of study treatment (maximum up to 45 days)

Population: SAS included all participants who took at least 1 dose of study intervention.

An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAEs were any AEs that occurred on or after the first dose of study treatment up to 35 days post last dose of study treatment. A serious adverse event (SAE) was any untoward medical occurrence at any dose that: resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/ incapacity; resulted in congenital anomaly/birth defect.
