Study Endpoints

Primary Endpoints

Maximum Observed Analyte Concentration (Cmax) of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

The Cmax is the maximum observed analyte concentration.

Area Under Analyte Concentration From Time Zero to the Last Quantifiable Concentration (AUC [0-last]) of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

AUC (0-last) defined as the area under the analyte concentration-time curve from time zero to time of the last measurable (non-BQL) analyte concentration, calculated by linear-linear trapezoidal summation.

Plasma analyte concentration 24 hours (C24) Post Dose of Selexipag and ACT-333679
Predose and 0 to 72 hours postdose

C24 defined as plasma analyte concentration at 24 hours postdose.

Area Under the Analyte Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-infinity])
Predose and 0 to 72 hours postdose

AUC (0-infinity) is defined the area under the analyte concentration-time curve from time zero to infinity time, calculated as the sum of AUC (0-last) and C(last)/lambda(z); wherein AUC (0-last) is area under the plasma concentration-time curve from time zero to last measurable concentration, C(last) is the last observed measurable concentration, and lambda(z) is apparent terminal elimination rate constant.

ArmTypeDescription
Cohort 1: Selexipag Matrix TabletsEXPERIMENTALParticipants will receive oral doses of selexipag matrix tablets based on release profiles (IR=immediate release, F=fast release, M=medium release and S=slow release) in treatment sequence 1 (IR+F+M+S), treatment sequence 2 (F+S+IR+M), treatment sequence 3 (M+ IR+ S+F) and treatment sequence 4 (S+M+F+IR) in periods 1, 2, 3, and 4, respectively under fasted condition. A washout period of at least 7 days will be maintained between each treatment period.
Cohort 2: Selexipag Encapsulated PelletsEXPERIMENTALParticipants will receive oral doses of selexipag encapsulated) pellets based on release profiles (IR=immediate release, F=fast release, M=medium release and S=slow release) in treatment sequence 1 (IR+F+M+S), treatment sequence 2 (F+S+IR+M), treatment sequence 3 (M+ IR+ S+F) and treatment sequence 4 (S+M+F+IR) in periods 1, 2, 3, and 4, respectively under fasted condition. A washout period of at least 7 days will be maintained between each treatment period.

Frequently asked questions about Selexipag matrix

What is Selexipag matrix?

Selexipag matrix is an investigational small molecule developed by Johnson & Johnson (ticker JNJ). It is a matrix tablet formulation studied in a Phase 1 clinical trial in healthy male participants. The program is in early clinical development, and no approved indication has been disclosed for this matrix formulation.

What does Selexipag matrix target?

Selexipag matrix targets PTGIR, the prostacyclin receptor, and acts as an agonist at that receptor. Agonist activity at PTGIR is the mechanism described for this asset. The matrix tablet is a small molecule formulation being evaluated in Phase 1 testing by Johnson & Johnson.

Who makes Selexipag matrix?

Selexipag matrix is developed by Johnson & Johnson, which trades under the ticker JNJ. The company is the sponsor behind the Phase 1 program for this matrix tablet formulation of selexipag. Development remains at the early clinical stage.

What phase is Selexipag matrix in?

Selexipag matrix is in Phase 1 clinical development. It is investigational and has not been approved. One Phase 1 trial has been completed, with no active trials currently listed. The completed study enrolled 24 participants and was conducted in Belgium.

What clinical trials is Selexipag matrix in?

Selexipag matrix has been studied in one completed Phase 1 trial, NCT04266756, titled A Study of Selexipag in Healthy Male Participant. That randomized, controlled trial enrolled 24 healthy male volunteers aged 18 years and older in Belgium. No active trials are currently listed for this asset.

Is Selexipag matrix the same as Selexipag matrix tablet?

Yes, Selexipag matrix and Selexipag matrix tablet refer to the same asset. The matrix tablet is the alternative name used for this formulation of selexipag. Both names point to the same Phase 1 small molecule program targeting PTGIR that is being developed by Johnson & Johnson.
