Potential Pharmacokinetic Interaction Between Selexipag and Midazolam in Healthy Male Subjects

October 12, 2016 updated by: Actelion

A Single-center, Open-label, Randomized, Two-treatment Crossover Study to Investigate the Effect of Selexipag on the Pharmacokinetics of Midazolam and Its Metabolite 1-hydroxymidazolam in Healthy Male Subjects

The primary purpose of this study is to evaluate the effect of repeated doses of selexipag on the pharmacokinetics of a single oral dose of midazolam (i.e., how long and how much midazolam is present in the blood)

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

In order to exclude an inductive effect of selexipag in the gastrointestinal tract, this study aims at investigating the effect of selexipag on the PK of midazolam, a sensitive substrate of both hepatic and intestinal cytochrome P450 3A4 (CYP3A4).

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

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.

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
Cmax of midazolam following administration of midazolam alone and in combination with selexipag
Time Frame: From pre-dose up to 24 hours after midazolam admisnitration for each treatment period
Cmax is the maximum observed plasma concentration and is directly derived from the individual plasma concentration time curves of midazolam
From pre-dose up to 24 hours after midazolam admisnitration for each treatment period
AUC(0-inf) of midazolam following administration of midazolam alone and in combination with selexipag
Time Frame: From pre-dose up to 24 hours after midazolam admisnitration for each treatment period
AUC(0-inf) is the area under the plasma concentration-time curves of midazolam, calculated from time 0 (pre-dose) to the extrapolated infinite time
From pre-dose up to 24 hours after midazolam admisnitration 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
Cmax of 1-hydroxymidazolam following administration of midazolam alone and in combination with selexipag
Time Frame: From pre-dose up to 24 hours after midazolam admisnitration

From pre-dose up to 24 hours after midazolam admisnitration
tmax of midazolam and 1-hydroxymidazolam following administration of midazolam alone and in combination with selexipag
Time Frame: From pre-dose up to 24 hours after midazolam admisnitration
tmax is the time to reach Cmax of midazolam and its metabolite (1-hydroxymidazolam), respectively
From pre-dose up to 24 hours after midazolam admisnitration
t½ of midazolam and 1-hydroxymidazolam following administration of midazolam alone and in combination with selexipag.
Time Frame: From pre-dose up to 24 hours after midazolam admisnitration
t½ is the terminla half-life of midazolam and its metabolite (1-hydroxymidazolam), and corresponds to the period of time required for the concentration levels of midazolam and its metabolite to be reduced by one-half, respectively
From pre-dose up to 24 hours after midazolam admisnitration
Trough concentration of selexipag and its metabolite ACT-333679 at steady-state
Time Frame: Days 1, 4, 7, 10,12 and 13
Trough concentrations are measured before morning administration of selexipag
Days 1, 4, 7, 10,12 and 13

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of treatment-emergent adverse events and serious adverse events
Time Frame: Up to 39 days (from Day 1 of Period 1 to end of study of 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
Up to 39 days (from Day 1 of Period 1 to end of study of Period 2)
