- Registration Number
- NCT03422328
- Lead Sponsor
- Actelion
- Brief Summary
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.
- 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.

- Primary Outcome Measures
Name Time Method Incident Rate of Treatment-emergent Adverse Event From Day 1 to End of study (EoS) visit (an average of 3 years) 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.
Incident rate of treatment-emergent adverse events (AEs) leading to premature discontinuation of study treatment From Day 1 to EoS visit (an average of 3 years) 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.
Incident rate of treatment-emergent serious adverse events (SAEs) From Day 1 to EoS visit (an average of 3 years) 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.
Number of pregnancies with maternal exposure to macitentan From Day 1 to EoS visit (an average of 3 years) Pregnancies with maternal exposure to macitentan will be recorded.
