Study to Assess the Tolerability and the Safety of the Transition From Inhaled Treprostinil to Oral Selexipag in Patients With Pulmonary Arterial Hypertension

Completed · Phase 3

Conditions studied: Pulmonary Arterial Hypertension

In brief

This study enrolls patients with pulmonary arterial hypertension (PAH) treated with inhaled treprostinil. During the study, the treatment with inhaled treprostinil will be tapered off and simultaneously replaced with an oral treatment (selexipag) targeting the disease in a similar way. The purpose of the study is i) to investigate the safety and tolerability of oral selexipag in patients who transition from inhaled treprostinil, ii) to investigate the effects of oral selexipag on PAH severity and exercise ability before and after transition, and iii) to gain new information about the patients experience taking oral selexipag compared to inhaled treprostinil. Study participants may stay in the study until the FDA has granted marketing authorization.

You may qualify if…

• Male and female patients aged from 18 to 75 years (inclusive) with pulmonary arterial hypertension (PAH).
• Etiology of PAH belonging to one of the following subgroups: idiopathic PAH, Heritable PAH, drug or toxin induced, associated with connective tissue disease, associated with HIV infection, associated with congenital heart disease with simple systemic-to-pulmonary shunt at least 1 year after surgical repair.
• Women of childbearing potential are eligible only if the following apply: Negative serum pregnancy test at Visit 1 and a negative urine pregnancy test at Visit on Day 1, agreement to undertake monthly urine pregnancy tests during the study and up to 30 days after study drug discontinuation, agreement to use efficient methods of birth control from Visit 1 up to at least 30 days after study treatment discontinuation.
• Documented hemodynamic diagnosis of PAH by right heart catheterization (RHC).

• History of left-sided heart disease.
• Left ventricular disease/dysfunction risk factors.
• Documented pericardial effusion within 90 days prior to Visit 1.
• Documented severe renal insufficiency.
• Receiving or having received any investigational drugs within 90 days before Day 1.
• Having received selexipag at any time before Day 1.
• Acute or chronic impairment (other than dyspnea), limiting the ability to comply with study requirements.
• Recently conducted or planned cardio-pulmonary rehabilitation program based on exercise training during the study.
• Psychotic, addictive or other disorder limiting the ability to provide informed consent or to comply with study requirements.
