Study drug intake in subsequent treatment periods in an individual participant will be separated by a washout period of at least 10 days.
Receives: Drug: FDC of macitentan/tadalafil (10 mg/20 mg); Drug: Macitentan 10 mg; Drug: Tadalafil 20 mg
Treatment Sequence BAExperimentalParticipants will receive Treatment B in treatment period 1 followed by Treatment A in treatment period 2 on Day 1. Study drug intake in subsequent treatment periods in an individual participant will be separated by a washout period of at least 10 days.
Receives: Drug: FDC of macitentan/tadalafil (10 mg/20 mg); Drug: Macitentan 10 mg; Drug: Tadalafil 20 mg

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum Observed Plasma Analyte Concentration (Cmax) of Macitentan, its Metabolite ACT-132577, and Tadalafil

    Cmax is defined as maximum observed plasma analyte concentration.

    Measured: Predose and up to 216 hours post dose (Up to Day 10)

  2. Area Under the Concentration-time Curve from Time Zero to the Last Quantifiable Concentration (AUC [0-last]) of Macitentan, its Metabolite ACT-132577, and Tadalafil

    AUC(0-last) is the area under the plasma analyte concentration-time curve from time zero to time of the last quantifiable (non-below quantification limit [non-BQL]) concentration, calculated by linear-linear trapezoidal summation.

    Measured: Predose and up to 216 hours post dose (Up to Day 10)

  3. Area Under the Concentration-time Curve from Time Zero to Infinity (AUC [0-infinity]) of Macitentan, its Metabolite ACT-132577, and Tadalafil

    AUC (0-infinity) is the area under the analyte concentration-time curve (AUC) from time zero to infinite 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 (non-BQL) analyte concentration; and lambda(z) is apparent terminal elimination rate constant.

    Measured: Predose and up to 216 hours post dose (Up to Day 10)

Secondary outcomes (1)
  1. Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    An 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.

    Measured: Up to 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing FDC of macitentan/tadalafil (10 mg/20 mg), Macitentan 10 mg and Tadalafil 20 mg in people with Healthy, run by Janssen Research & Development, LLC at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Observed Plasma Analyte Concentration (Cmax) of Macitentan, its Metabolite ACT-132577, and Tadalafil (time frame: Predose and up to 216 hours post dose (Up to Day 10)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2025; AzTrials last refreshed its copy on 2 Nov 2026.
