Long-Term Safety Follow-Up for Pulmonary Hypertension Participants Continuing Macitentan, Selexipag, or MacitentanTadalafil Treatment After Parent Study

What this Trial Is About

This research aims to provide continued access to study treatments for participants with pulmonary hypertension who have completed previous clinical studies but have no other way to receive these treatments. It focuses on assessing the long-term safety of the study drugs macitentan, selexipag, and a fixed dose combination of macitentan and tadalafil. The study is designed for participants who benefited from these treatments during parent studies and have no alternative approved therapies available. Participants will continue receiving oral study drugs macitentan once daily with doses adjusted for children by weight, selexipag twice daily with dosing based on previous maintenance dose and body weight for children, or a fixed dose combination of macitentan and tadalafil once daily. Adults will have study visits every six months, while pediatric participants will have visits every three months. These visits will collect information on the treatments safety and effectiveness until the participant stops treatment, the drug becomes commercially available, or the study ends prematurely. During the study, participants will undergo regular assessments to monitor safety, including tracking treatment-emergent adverse events, serious adverse events, events leading to discontinuation, and deaths for up to 84 months. Visits will include collecting efficacy and safety data to ensure ongoing monitoring. The overall participation duration may extend for several years, allowing careful observation of long-term effects and safety of these treatments in people with pulmonary hypertension.
