About this study

Official title: A Single-center, Open-label, Single-dose, Randomized, 3-way Crossover Phase 1 Study in Healthy Adult Participants to Assess the Bioequivalence of the Combination of Macitentan/Tadalafil (10 mg/20 mg) Administered as a Fixed Dose Combination Formulation Compared to the Reference Free Combination of 10 mg Macitentan (Opsumit®) and 20 mg Tadalafil (Adcirca®) as Well as the Food Effect of the Fixed-dose Combination Formulation

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 and its Metabolite JNJ-68212820, and Tadalafil.

    Cmax is defined as the maximum observed plasma analyte concentration.

    Measured: Predose up to 216 hours (up to Day 10)

  2. Area Under the Plasma Analyte Concentration Time Curve of Macitentan, its Metabolite JNJ-68212820, and Tadalafil from Time Zero to Time of the Last Quantifiable Concentration (AUC [0-Last])

    AUC (0-last) is defined as area under the plasma analyte concentration time curve of macitentan, its metabolite JNJ-68212820 and tadalafil from time 0 to the time of the last quantifiable (non-below quantification limit [non-BQL]) concentrations.

    Measured: Predose up to 216 hours (up to Day 10)

  3. Area Under the Plasma Concentration Time Curve of Macitentan and its Metabolite JNJ-68212820, and Tadalafil from Time Zero to Infinite time (AUC [0-Infinity])

    AUC (0-infinity) is defined as area under the plasma concentration-time curve of macitentan and its metabolite JNJ-68212820, and tadalafil from time 0 to infinite time, calculated as the sum of AUC (0-last) and C(last)/lambda(z) where C(last) is the last observed measurable (non-BQL) plasma analyte concentration.

    Measured: Predose up to 216 hours (up to Day 10)

Secondary outcomes (7)
  1. Time to Reach Maximum Observed Plasma Analyte Concentration (Tmax) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    (AUC 0-72h) is defined as the area under the plasma concentration-time curve of macitentan and its metabolite JNJ-68212820, tadalafil from time 0 to 72 hours postdose, calculated by linear-linear trapezoidal summation.

    Measured: Predose up to 216 hours (up to Day 10)

  3. Apparent Elimination Half-Life (t1/2) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    t1/2 is defined as apparent elimination half-life calculated as 0.693/lambda(z).

  4. Apparent Terminal Elimination Rate Constant (lambda z) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    Apparent terminal elimination rate constant is estimated by linear regression using the terminal log-linear phase of the log-transformed concentration versus time curve.

    Measured: Predose up to 216 hours (up to Day 10)

  5. Total Apparent Oral Clearance (CL/F) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    CL/F is defined as total apparent oral clearance calculated as dose/AUC(0-infinity).

    Measured: Predose up to 216 hours (up to Day 10)

  6. Apparent Volume of Distribution (Vd/F) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    Vd/F is defined as apparent volume of distribution calculated as dose/(lambda(z) *AUC (0 to infinity).

    Measured: Predose up to 216 hours (up to Day 10)

  7. Last Observed Measurable Plasma Concentration (Clast) of Macitentan and its Metabolite JNJ-68212820, Tadalafil

    Clast is defined as the last observed measurable (non-BQL) plasma concentration of macitentan and its metabolite JNJ-68212820, Tadalafil.

    Measured: Predose up to 216 hours (up to Day 10)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Macitentan 10 mg, Tadalafil 20 mg and Macitentan 10 mg/Tadalafil 20mg FDC in people with Healthy, run by Actelion at 1 site in United States.

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 5 inclusion and 4 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 United States. 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 and its Metabolite JNJ-68212820, and Tadalafil. (time frame: Predose up to 216 hours (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.
