A Study of Selexipag in Participants Who Participated in a Previous Selexipag Study
The purpose of this study is to assess the long-term safety of selexipag in participants who were previously enrolled in an Actelion-sponsored study with selexipag and who derived benefit from selexipag in indications for which a positive benefit-risk has been established.
A Study of Single Doses of MK -5475 on Pulmonary Vascular Resistance (MK-5475-002)
This is a 2-part, 4-panel study of MK-5475 in participants with Group 1 pulmonary arterial hypertension (PAH). Part 1 is a double-blind, randomized, single-ascending dose assessment of the safety, tolerability and pharmacokinetics (PK) of inhaled MK-5475. Part 2 of this study is an open-label study and will assess the safety, tolerability, PK and pharmacodynamics of inhaled MK-5475 at dose determined by results of Part 1 and Period 1 of Part 2 of the study. There is no formal hypothesis to be tested.
A Study of Sotatercept for the Treatment of Pulmonary Arterial Hypertension
This study evaluates the effect of sotatercept (ACE-011) in adults with Pulmonary Arterial Hypertension. Each eligible participant will receive standard of care (SOC) plus sotatercept (ACE-011) for a 24 week treatment period, followed by an 18 month Extension Period and an 8 week follow up period.
A Study of Sotatercept for the Treatment of Pulmonary Arterial Hypertension (PAH)
Study A011-09 is designed to assesses the efficacy and safety of sotatercept (ACE-011) relative to placebo in adults with pulmonary arterial hypertension (PAH). Eligible participants will receive study treatment for 6 months in the Placebo-Controlled Treatment Period, and then will be eligible to enroll into an 18- month Extension Period during which all participants will receive sotatercept. All treated patients will be also undergo follow-up period after last study drug treatment.
A Study of Sotatercept for the Treatment of Pulmonary Arterial Hypertension (STELLAR)
The objectives of this study are to evaluate the efficacy and safety of sotatercept treatment (plus background PAH therapy) versus placebo (plus background PAH therapy) at 24 weeks in adults with PAH.
A Study of Tadalafil in Pediatric Participants With Pulmonary Arterial Hypertension (PAH)
The main purpose of this study is to evaluate the safety and efficacy of tadalafil in pediatric participants with pulmonary arterial hypertension. Participants will receive study treatment for 6 months in the double-blind period (Period 1), and then will be eligible to enroll into an open-label 2 year extension period (Period 2) during which participants will receive tadalafil.
A Study to Assess Pulsed Inhaled Nitric Oxide in Subjects With Pulmonary Fibrosis at Risk for Pulmonary Hypertension
A randomized, double-blind, placebo-controlled dose escalation and verification study to assess the safety and efficacy of pulsed inhaled nitric oxide (iNO) versus placebo in subjects at risk for pulmonary hypertension associated with pulmonary fibrosis on long term oxygen therapy. (REBUILD)
A Study to Assess Whether Macitentan Delays Disease Progression in Children With Pulmonary Arterial Hypertension (PAH)
This is a prospective, multicenter, open-label, randomized, controlled, parallel group, group-sequential, event-driven Phase 3 study to evaluate efficacy, safety and pharmacokinetics (PK) of macitentan in children.
A Study to Evaluate Efficacy and Safety of Macitentan 75 mg in Inoperable or Persistent/Recurrent Chronic Thromboembolic Pulmonary Hypertension
The purpose of the study is to evaluate the effect of macitentan 75 mg versus placebo on exercise capacity at Week 28 in participants with chronic thromboembolic pulmonary hypertension (CTEPH).
A Study to Find Out if Selexipag is Effective and Safe in Patients With Chronic Thromboembolic Pulmonary Hypertension When the Disease is Inoperable or Persistent/Recurrent After Surgery and/or Interventional Treatment
Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in subjects with inoperable or persistent/recurrent CTEPH.
