About this study

Official title: mUlticenter, Single-arM, Open-laBel, Long-teRm Safety Study With macitEntan in Patients With puLmonary Arterial Hypertension previousLy Treated With mAcitentan in Clinical Studies

The aim of the trial is to study the long-term safety of macitentan and to provide continued treatment with macitentan to patients with pulmonary arterial hypertension (PAH) and Chronic thromboembolic pulmonary hypertension (CTEPH) who were previously treated with macitentan in clinical studies.

Read the detailed description

The purpose of this study is to provide continued treatment with macitentan to subjects with PAH or CTEPH who participated in "parent studies" and to continue to accrue long-term safety data. The design of this study is widely used in clinical programs to give participants in a clinical study access to an effective study treatment beyond completion of the parent study. This is considered the best option to collect long-term safety and tolerability information of macitentan 10 mg and survival status of participants with PAH and CTEPH. "Parent study/studies" refer to a number of clinical studies with macitentan that are conducted in different clinical classification of PAH and CTEPH (NCT00667823, NCT02112487, NCT02310672, NCT02968901, NCT02558231, NCT02382016, NCT02060721) and may be completed before the participants have access to commercial macitentan in their country of residence. The "parent studies" are fully or partially running in countries where no access to commercial macitentan is expected in the near future.

What is being measured

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

  1. Incident Rate of Treatment-emergent Adverse Event

    An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. A treatment-emergent AE is any AE temporally associated with the use of study treatment.

    Measured: From Day 1 to End of study (EoS) visit (an average of 3 years)

  2. Incident rate of treatment-emergent adverse events (AEs) leading to premature discontinuation of study treatment

    Any AE will be recorded that 1) is (temporally) associated with the use of study treatment whether or not considered by the investigator as related to study treatment and 2) leads to premature discontinuation of study medication.

    Measured: From Day 1 to EoS visit (an average of 3 years)

  3. Incident rate of treatment-emergent serious adverse events (SAEs)

    Any SAE as defined by the ICH guidelines will be recorded. Any hepatic AE that leads to discontinuation of study treatment will be defined as SAE.

    Measured: From Day 1 to EoS visit (an average of 3 years)

  4. Number of pregnancies with maternal exposure to macitentan

    Pregnancies with maternal exposure to macitentan will be recorded.

    Measured: From Day 1 to EoS visit (an average of 3 years)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing macitentan in people with Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension, run by Actelion at 34 sites in 7 countries.

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 3 inclusion and 8 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 27 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 34 sites in France, Russia, Poland, Ukraine, Belarus and 2 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Incident Rate of Treatment-emergent Adverse Event (time frame: From Day 1 to End of study (EoS) visit (an average of 3 years)). The study lists 4 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 27 Apr 2025.
