Safety Study of the Switch From Oral Selexipag to Intravenous Selexipag in Subjects With Stable Pulmonary Arterial Hypertension
brief 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.
detailed description
After screening (Visit 1), each subject will participate in the following consecutive treatment periods: Period 1(treatment with oral selexipag at Visit 2/Day 1), Period 2 (treatment with intravenous selexipag at Visit 2/ Day 2 and Day 3), Period 3 (treatment with oral selexipag starting in the evening of Visit 2/Day 3 and ending 7 to 11 days later at Visit 3). Then a safety follow-up period is planned up to end of study visit (EOS), which occurs between Day 33 and Day 40.
