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

Frequently asked questions about Etrasimod Immediate Release

What is Etrasimod Immediate Release?

Etrasimod Immediate Release is an investigational small molecule developed by Pfizer, Inc. (PFE). It is currently in Phase 1 clinical development. The immediate release designation distinguishes this formulation from other versions of etrasimod.

What does Etrasimod Immediate Release target?

Etrasimod Immediate Release targets the sphingosine-1-phosphate receptors S1PR1, S1PR4, and S1PR5, where it acts as an agonist. This receptor activity is the basis for its investigational mechanism.

Who is developing Etrasimod Immediate Release?

Etrasimod Immediate Release is being developed by Pfizer, Inc., which trades on the New York Stock Exchange under the ticker symbol PFE.

What phase is Etrasimod Immediate Release in?

Etrasimod Immediate Release is in Phase 1 clinical development. It is an investigational agent and has not been approved by the FDA for any indication.

What clinical trials is Etrasimod Immediate Release in?

Etrasimod Immediate Release has been evaluated in one completed Phase 1 trial, NCT06140290, titled "A Sub Study to Evaluate the Study Medication (Etrasimod) Using Wearable Sensors in Healthy Participants." The trial enrolled 8 healthy volunteers in Belgium.

Is Etrasimod Immediate Release the same as Etrasimod Immediate Release (IR)?

Yes, Etrasimod Immediate Release is also known as Etrasimod Immediate Release (IR). The IR abbreviation stands for immediate release, referring to the same formulation.
