Study Endpoints
Primary Endpoints
Area Under the Serum Concentration-Time Profile From Time Zero to 24 Hours (AUC0-24) of Etrasimod: Tasso PK Sampling
Pre-dose (0 hour), 1, 2, 4, 6, 8, 12 and 24 hours post-dose on Day 1 of each period

AUC0-24 was calculated as linear/log trapezoidal method. PK sampling: a) Treatment F/Reference: Tasso PK micro sampling was done by clinical research unit (CRU) staff participants at the CRU up to 24 hours post-dose and by participants 48-168 hours post-dose remotely; b) Treatment G/Test: Tasso PK micro sampling was done by participants at the CRU up to 24 hours post-dose and 48-168 hours post-dose remotely.

Area Under the Serum Concentration-Time Profile From Time 24 Hours to the Time of the Last Quantifiable Concentration (AUC24hr-last) of Etrasimod: Tasso PK Sampling
24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

AUC24hr-last was calculated as linear/log trapezoidal method. PK sampling: a) Treatment F/Reference: Tasso PK micro sampling was done by CRU staff participants at the CRU up to 24 hours post-dose and by participants 48-168 hours post-dose remotely; b) Treatment G/Test: Tasso PK micro sampling was done by participants at the CRU up to 24 hours post-dose and 48-168 hours post-dose remotely.

Area Under the Serum Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUCinf) of Etrasimod: Tasso PK Sampling
Pre-dose (0 hour), 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

AUCinf was calculated as AUClast + (Clast\*/kel), where AUClast is area under the plasma concentration-time profile from time zero to the time of the last quantifiable concentration (Clast). Clast is the predicted plasma concentration at the last quantifiable time point and Kel is the terminal phase rate constant. PK sampling: a) Treatment F/Reference: Tasso PK micro sampling was done by CRU staff participants at the CRU up to 24 hours post-dose and by participants 48-168 hours post-dose remotely; b) Treatment G/Test: Tasso PK micro sampling was done by participants at the CRU up to 24 hours post-dose and 48-168 hours post-dose remotely.

Maximum Observed Concentration (Cmax) of Etrasimod: Tasso PK Sampling
Pre-dose (0 hour), 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

PK sampling: a) Treatment F/Reference: Tasso PK micro sampling was done by CRU staff participants at the CRU up to 24 hours post-dose and by participants 48-168 hours post-dose remotely; b) Treatment G/Test: Tasso PK micro sampling was done by participants at the CRU up to 24 hours post-dose and 48-168 hours post-dose remotely.

Secondary Endpoints
AUC0-24 of Etrasimod: Tasso and Venous PK Sampling
Pre-dose (0 hour), 1, 2, 4, 6, 8, 12 and 24 hours post-dose on Day 1 of each period
AUC24hr-last of Etrasimod: Tasso and Venous PK Sampling
24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period
AUCinf for Etrasimod: Tasso and Venous PK Sampling
Pre-dose (0 hour), 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period
