Safety Study of the Switch From Oral Selexipag to Intravenous Selexipag in Subjects With Stable Pulmonary Arterial Hypertension
Condition: Pulmonary Arterial Hypertension
MeSH terms: Pulmonary Arterial Hypertension; Familial Primary Pulmonary Hypertension; Hypertension
Intervention: i.v. selexipag; oral selexipag (Uptravi)
Intervention description: Selexipag for intravenous administration, twice daily as an infusion over 87 min. The dose is individualized for each subject to correspond to his/her current oral dose of Uptravi®.; Uptravi is used as an auxiliary medicinal product, as part of the PAH standard treatment and administered according to the local prescribing information
Intervention MeSH terms: Selexipag
Phase: Phase 3
Study type: Interventional
Primary purpose: Treatment
Intervention model: Single Group Assignment
Masking: None (Open Label)
Enrollment: 20.0
Sex: All
Minimum age: 18 Years
Maximum age: 75 Years
Healthy volunteers: No
Keywords: switch; intravenous; selexipag

Summary:

      The development of selexipag for intravenous administration will be useful to avoid treatment
      interruptions in patients with pulmonary arterial hypertension (PAH) already treated with
      selexipag administered orally as tablets (Uptravi®). The target population for intravenous
      selexipag includes those PAH patients who are hospitalized and are unable to swallow tablets
      of Uptravi.

      The primary objective of this study is to assess whether it is safe for patients with PAH to
      temporarily change from selexipag tablets (Uptravi®) to selexipag given directly into a vein
      (intravenous selexipag), and then switching back to the initial oral dose of selexipag.
