Brief Summary: The purpose of this multi-center, open-label, safety and tolerability study was to assess the addition of oral treprostinil (UT-15C sustained release \[SR\] tablets) to subjects currently receiving Tyvaso (treprostinil) inhalation solution. During the 24-week evaluation period, the study evaluated the changes in the following assessments: hemodynamics, 6-minute walk test (6MWT), Borg dyspnea score, N-Terminal pro-brain natriuretic peptide (NT-proBNP), World Health Organization (WHO) Functional Class, and safety assessments. Eligible subjects had a diagnosis of pulmonary arterial hypertension (PAH), currently were receiving Tyvaso, and may have been receiving other approved PAH specific oral therapies (endothelin receptor antagonists \[ERAs\] and/or phosphodiesterase type 5 inhibitor \[PDE5-I\], if at a stable dose for ≥30 days). At Baseline, subjects received the first dose of 0.125 mg UT-15C SR.
Detailed Description: This was a multi-center, open-label, safety and tolerability study in WHO Group 1 PAH subjects adding UT-15C SR to Tyvaso and PAH approved background therapy. This study had a 24-week evaluation period followed by a long term safety period. Six study visits occurred in the first 24 weeks of study; Screening, Baseline, Week 4, Week 8, Week 12, and Week 24 visits. Right heart catheterization occurred between 2-4 hours following the last Tyvaso dose at Baseline (prior to the administration of UT-15C SR) and Week 24.
