Absolute Bioavailability of a Single Oral Dose of Selexipag in Healthy Subjects

January 31, 2025 updated by: Actelion

Single-center, Open-label, Phase 1 Study Consisting of a Single-dose Pilot Phase and a Randomized, Two-way Crossover, Single-dose Main Phase to Investigate the Absolute Bioavailability of a Single Oral Dose of Selexipag in Healthy Male Subjects

The primary purpose of this phase 1 study is to investigate the absolute bio-availability of a single oral dose of selexipag, i.e., to assess the amount of selexipag which reaches the blood when administered as an oral tablet (ACT-293987) compared to an intravenous administration in healthy subjects.

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A pilot phase was conducted in 3 male subjects before the main phase for assessment of absolute bio-availability conducted in 16 other male subjects. The pilot phase aimed to determine the intravenous dose to be used in the main phase based on safety data and pharmacokinetics data.

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.

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

Inclusion Criteria:

  • Signed informed consent prior to any study-mandated procedure
  • Aged from 18 to 45 (inclusive) at screening
  • Body mass index (BMI) from 18.0 to 28.0 kg/m2 (inclusive) at screening
  • Healthy on the basis of physical examination, cardiovascular assessments and laboratory tests

Exclusion Criteria:

  • Any contraindication to the study drug formulations
  • History or presence of any disease or 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 drugs

Experimental: Intravenous selexipag (Pilot phase)
Subjects received a 20-minute intravenous (i.v.) infusion of 50 µg selexipag

Selexipag was reconstituted in sterile 0.9% w/v NaCl before infusion via an infusion pump at a rate of 2.5 µg/min.
Other Names:
  • ACT-293987

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
Absolute bioavailability (F) of selexipag
Time Frame: From pre-dose to 72 hours post-dose
F was calculated using the areas under the plasma concentrations curves extrapolated to infinity [AUC(0-inf)] after oral (po) and intravenous (iv) doses, obtained during the main phase, and using the following formula: AUC(0-inf)po * iv dose / AUC(0-inf)iv * oral dose
From pre-dose to 72 hours post-dose
Area under the plasma concentration-time curve from time 0 to infinity [AUC(0-inf)] of selexipag
Time Frame: From pre-dose to 72 hours post-dose
AUC(0-inf) was calculated from the concentration-time profile of selexipag after both oral and intravenous administration during the main phase
From pre-dose to 72 hours post-dose

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
Areas under the plasma concentration-time curve from time 0 to time t [AUC(0-t)] of selexipag and its active metabolite
Time Frame: From pre-dose to 72 hours post-dose
AUC from time 0 to time t of the last measured concentration above the limit of quantification [AUC(0-t)] were calculated for selexipag and its active metabolite, from their respective concentration-time profiles, after both intravenous (pilot phase and main phase) and oral administration (main phase) of selexipag
From pre-dose to 72 hours post-dose
Maximum plasma concentration (Cmax) of selexipag and its active metabolite
Time Frame: From pre-dose to 72 hours post-dose
Cmax of selexipag and its active metabolite were directly obtained from the plasma concentration-time curves after both intravenous (pilot phase and main phase) and oral administration (main phase) of selexipag
From pre-dose to 72 hours post-dose
time to reach maximum plasma concentration (tmax) of selexipag and its active metabolite
Time Frame: From pre-dose to 72 hours post-dose
tmax of selexipag and its active metabolite were directly obtained from the plasma concentration-time curves after both intravenous (pilot phase and main phase) and oral administration (main phase) of selexipag
From pre-dose to 72 hours post-dose
Terminal half-life [t(1/2)] of selexipag and its active metabolite
Time Frame: From pre-dose to 72 hours post-dose
t(1/2) of selexipag and its active metabolite were calculated after both intravenous (pilot phase and main phase) and oral administration (main phase) of selexipag from the concentration-time profiles
From pre-dose to 72 hours post-dose
Number of participants experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: 4 days
