2. The subject has a diagnosis of symptomatic World Health Organization (WHO) Group 5.1 chronic hemolytic anemia PH.
3. The subject must have a Baseline 6MWD greater than 150 meters, in the absence of a concurrent injury, illness, or other confounding factor.
4. The subject has pulmonary function tests conducted within 6 months of Screening or during the Screening period.
5. The subject must be on stable doses of other medical therapy for at least 30 days prior to randomization with no dose adjustments, additions, or discontinuations.
6. The subject must be optimally treated with conventional PH therapy for at least 10 days prior to randomization with no additions, discontinuations, or dose changes.
7. Subjects receiving an endothelin receptor antagonist (ERA) must have been receiving therapy for greater than 90 days, and have reached and maintained a stable dose for a minimum of 30 days prior to randomization.
8. Subjects receiving calcium channel blockers must have been on a stable dose for a minimum of 3 months prior to randomization.
You may not be if
1. The subject is pregnant or lactating.
2. The subject has previously received oral treprostinil or is receiving a phosphodiesterase type 5 inhibitor (PDE5-I).
3. The subject has received a prostacyclin within 30 days prior to start of the study, or had previous intolerance or significant lack of efficacy to any prostacyclin or prostacyclin analogue that resulted in discontinuation or inability to titrate that therapy effectively.
4. The subject has had any other background conventional therapies for PH added, removed, or doses adjusted within 10 days prior to randomization.
5. The subject has any disease associated with pulmonary arterial hypertension (PAH).
6. The subject has had a vaso-occlusive crisis, acute chest syndrome event, or unscheduled transfusion within 30 days of randomization.
7. The subject has a history of ischemic heart disease, including a previous myocardial infarction or symptomatic coronary artery disease, within 6 months prior to Screening or a left ventricular ejection fraction less than 40% assessed by either multigated angiogram (MUGA), angiography, or echocardiogram.
8. The subject has alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels 3 times or greater than the upper limit of normal, clinically significant liver disease/dysfunction, or known Child-Pugh Class B or C hepatic disease at Screening.
9. The subject has chronic renal insufficiency, as defined by the requirement for dialysis.
10. The subject has a musculoskeletal disorder, any disease that is likely to limit ambulation, or is connected to a machine that is not portable.
11. The subject has an unstable psychiatric condition or is mentally incapable of understanding the objectives, nature, or consequences of the study, or has any condition which in the Investigator's opinion would constitute an unacceptable risk to the subject's safety.
