Study Endpoints

Primary Endpoints

Number of Participants With at Least One Adverse Event (AE)
From Day 1 to Day 37

AE is any untoward medical event that occurs in a participant during the course of the study whether or not considered by the investigator as related to the study treatment.

Number of Participants With Prostacyclin-associated Adverse Events
From Day 1 to Day 37

Prostacyclin-associated AE include headache, diarrhea, nausea, vomiting, jaw pain, myalgia, pain in the extremity, flushing and arthralgia.

Number of Participants With Adverse Event Related to Injection Site Reactions
From Day 2 to Day 3

This is the number of participants with at least one clinically significant reaction at the injection site (e.g., erythema/redness, tenderness, swelling, induration, hemorrhage at the injection site) occurring on the days of intravenous (iv) selexipag injection.

Number of Participants With Prostacyclin-associated AEs Leading to Study Treatment Discontinuation
From Day 2 to Day 3

This is the number of subjects who discontinued the i.v. selexipag treatment due to prostacyclin-associated adverse events (headache, diarrhea, nausea, vomiting, jaw pain, myalgia, pain in the extremity, flushing and arthralgia).

Number of Participants With PAH-related Adverse Events
From Day 1 to Day 37

This is the number of participants with at least one AE considered to be related to pulmonary arterial hypertension during the course of the study.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) up to 3 Days After Study Intervention Discontinuation
Up to 3 days after study drug discontinuation (Up to 10.5 years)

An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. A TEAE is any AE temporally associated with the use of study drug (from study drug initiation until 3 days after study drug discontinuation), whether or not considered related to the study drug.

Number of Participants With Treatment-emergent Serious Adverse Events (SAEs) up to 3 Days After Study Intervention Discontinuation
Up to 3 days after study drug discontinuation (Up to 10.5 years)

An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above. Those SAEs occurring during study drug administration, that is, between study drug initiation and three days after study drug discontinuation, are defined as treatment-emergent SAEs.

Number of Participants With TEAEs Leading to Permanent Discontinuation of Study Intervention
Up to 10.5 years

An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. A TEAE is any AE temporally associated with the use of study drug (from study drug initiation until 3 days after study drug discontinuation), whether or not considered related to the study drug.

ArmTypeDescription
SelexipagEXPERIMENTALSubjects with stable pulmonary arterial hypertension (PAH) and currently treated with a stable oral dose of Uptravi will be switched to i.v. selexipag from Day 2 to Day 3 (2 infusions on Day 2 and 1 infusion on Day 3). Otherwise, they will continue with their current oral selexipag treatment throughout the study.
1EXPERIMENTALACT-293987, twice daily
ACT-293987 (NS-304) and matching placeboEXPERIMENTALSubjects will be randomized to the study following screening. Each subject will then undergo an acute hemodynamic study with right heart catheterization after a single oral administration of ACT-293987 (NS-304)on Day 0. The objectives are to collect data about the drug effect on the right heart hemodynamic parameters (PVR, calculated SVR and PVR/SVR) measured by right heart catheterization after single oral dose administration of NS-304 and to assess the safety and tolerability of a single oral dose of NS-304.

Frequently asked questions about i.v. selexipag

What is i.v. selexipag used for?

I.v. selexipag is used for pulmonary arterial hypertension (PAH). It is an investigational small molecule being developed by Johnson & Johnson (JNJ) as an intravenous formulation of selexipag, intended for patients with stable PAH. It is currently in Phase 3 clinical development.

Who makes i.v. selexipag?

I.v. selexipag is being developed by Johnson & Johnson, which trades under the ticker JNJ. The company is evaluating this intravenous formulation of selexipag for the treatment of pulmonary arterial hypertension.

What phase is i.v. selexipag in?

I.v. selexipag is in Phase 3 clinical development. It is an investigational drug and has not been approved by the FDA. A Phase 3 study has been completed to evaluate its safety in patients with stable pulmonary arterial hypertension.

What clinical trials is i.v. selexipag in?

I.v. selexipag has one completed Phase 3 clinical trial, NCT03187678, titled "Safety Study of the Switch From Oral Selexipag to Intravenous Selexipag in Subjects With Stable Pulmonary Arterial Hypertension." The study enrolled 20 participants in the United States and Germany.

Is i.v. selexipag the same as oral selexipag?

I.v. selexipag is an intravenous formulation of selexipag, which is also available as an oral medication. The Phase 3 trial NCT03187678 specifically studied switching from oral selexipag to intravenous selexipag in patients with stable pulmonary arterial hypertension.
