Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Healthy male adults receive a single dose of selexipag (200 µg) but using a different tablet strength (4 film-coated pediatric tablets of 50 µg versus one film-coated tablet of 200 µg selexipag) during each of the two study periods. There is a washout of 7-9 days between the two study treatment administrations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

Description

Key inclusion Criteria:

  • Male subjects aged from 18 to 45 years (inclusive) at screening
  • Signed informed consent form
  • Body mass index (BMI) between 18.0 and 28.0 kg/m2 (inclusive) at screening
  • Healthy on the basis of physical examination,cardiovascular assessments and laboratory tests

Key exclusion Criteria:

  • Any contraindication to the study treatments
  • History or clinical evidence of any disease or medical / surgical condition or treatment, which may put the subject at risk of participation in the study or may interfere with the absorption, distribution, metabolism or excretion of the study treatments
  • Any circumstances or conditions, which, in the opinion of the investigator, may affect the subject's full participation in the study or compliance with the protocol

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Area under plasma concentration-time curve [AUC(0-inf)] of selexipag and ACT-333679
Time Frame: From predose until 72 hours postdose for each treatment period
AUC(0-inf) is the area under plasma concentration-time curves for selexipag and its metabolite (ACT-333679), calculated from zero to the extrapolated infinite time
From predose until 72 hours postdose for each treatment period
Maximum plasma concentration (Cmax) of selexipag and ACT-333679
Time Frame: From predose until 72 hours postdose for each treatment period
Cmax is directly derived from the individual plasma concentration time curves for selexipag and its metabolite ACT-333679
From predose until 72 hours postdose for each treatment period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to reach Cmax (tmax) of selexipag and ACT-333679
Time Frame: From predose until 72 hours postdose for each treatment period
tmax is directly derived from the individual plasma concentration time curves for selexipag and its metabolite ACT-333679
From predose until 72 hours postdose for each treatment period
Terminal half-life (t½) of selexipag and ACT-333679
Time Frame: From predose until 72 hours postdose for each treatment period
The period of time required for the concentration levels of selexipag or its metabolite (ACT-333679) to be reduced by one-half
From predose until 72 hours postdose for each treatment period
Area under plasma concentration-time curve [AUC(0-t)] of selexipag and ACT-333679
Time Frame: From predose until 72 hours postdose for each treatment period
AUC(0-t) is the area under plasma concentration-time curves for selexipag and its metabolite (ACT-333679), calculated from zero to time t of the last measured concentration above the limit of quantification
From predose until 72 hours postdose for each treatment period
Incidence of treatment-emergent adverse events and serious adverse events
Time Frame: From first administration of selexipag (Day 1 Period 1) to end of study (Day 4, Period 2)
A treatment-emergent AE is any AE temporally associated with the use of a study treatment, whether or not considered related to the study treatment, including any abnormalities in ECG parameters, vital signs or laboratory tests
From first administration of selexipag (Day 1 Period 1) to end of study (Day 4, Period 2)
Incidence of safety events of interest
Time Frame: From first administration of selexipag (Day 1 Period 1) to end of study (Day 4, Period 2)
Events of interest include any abnormalities in ECG, vital signs or laboratory test results
From first administration of selexipag (Day 1 Period 1) to end of study (Day 4, Period 2)
