Brief summary

The purpose of this study is to look at how healthy adults process Etrasimod when assessed by wearable sensors. Etrasimod is taken without food and assessments taken by site staff and then by participants after training. The study is seeking participants who are: * Aged 18 or older * Male or female who are healthy as determined by medical assessment * Body-mass index (BMI) of 16 to 32, and a total body weight \> 50kg. The study will take up to 9 weeks, including the screening period. Participants will have to stay at the study clinic for at least 2 nights, in each of 2 study periods. Participants will take Etrasimod as a tablet by mouth without food. Blood samples will be taken both before and after participants take Etrasimod. Participants will also use wearable devices to assess blood pressure, heart rate and take further blood samples. A follow-up phone call will be made 20 to 27 days after the last study period.

Change From Baseline to Nadir in HR at Day 1

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.

Time frame: 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.
