Intervention Details:
    Drug: Treprostinil diethanolamine
    Subjects will each receive a single 1 mg sustained release tablet of treprostinil diethanolamine by mouth within 10 minutes of consuming each of four standardized meals on Study Days 1, 8, 15, and 22.
    Other Names:
    • UT-15C
    • UT-15C SR
