An Evaluation of the Safety and Efficacy of the Addition of UT-15C SR to Pulmonary Arterial Hypertension Patients Currently Receiving Tyvaso®

United Therapeutics·interventional·Posted Nov 22, 2011·Updated Dec 27, 2023

In Brief

A Phase 2 clinical trial evaluating UT-15C SR and Tyvaso Inhalation Solution for Pulmonary Arterial Hypertension. Completed, enrolled 18 participants across 6 sites.

Detailed 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.
