Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00058929 ↗	A Transition Study From Flolan® to Remodulin® in Patients With Pulmonary Arterial Hypertension	Completed	United Therapeutics	Phase 4	2002-10-01	This trial is a study of Remodulin in patients with pulmonary arterial hypertension who have been transitioned from Flolan therapy. The study consists of Screening, Baseline and Treatment Phases. Patients meeting all inclusion/exclusion criteria during the Screening Phase will enter the Baseline Phase, during which baseline exercise capacity, vital signs, and clinical signs and symptoms of the disease will be assessed. After confirmation of all inclusion/exclusion criteria, patients will be assigned to study drug (Remodulin or placebo) and will enter the Treatment Phase. The Treatment Phase begins with a Dose Transition Period, during which patients will begin receiving subcutaneous study drug at a low dose determined by the patient's current dose of Flolan. The study drug dose will be increased gradually while the Flolan dose is decreased gradually over a period of up to 14 days. The dose changes will continue until Flolan therapy has been discontinued and the patient is stable on study drug. Patients who are transitioned off Flolan, who are stable on study drug will be discharged from the clinic, and will continue to receive study drug on an outpatient basis. The patient will return to the clinic at Weeks 4 and 8 for assessments. Patients will remain on study drug for 8 weeks from the first dose of study drug. At Week 8, final assessments will be conducted and the patient will be dismissed from the study. Patients who successfully complete Week 8 assessments may be offered Remodulin therapy or other therapy, at the investigator's discretion.
NCT00060996 ↗	Study of Remodulin in Patients With Critical Limb Ischemia With No Planned Revascularization Procedures	Terminated	United Therapeutics	Phase 3	2003-02-01	The purpose of this study is to assess and compare the safety of continuous and daily subcutaneous Remodulin therapy in patients with critical limb ischemia (CLI) with no planned vascular interventional procedures; and to determine the effect of Remodulin on wound healing and treadmill walk distance.
NCT00147199 ↗	Clinical Investigation Into Inhaled Treprostinil Sodium in Patients With Severe Pulmonary Arterial Hypertension (PAH)	Completed	United Therapeutics	Phase 3	2005-06-01	This is a double-blind placebo-controlled clinical investigation into the efficacy and tolerability of inhaled treprostinil in patients with severe pulmonary arterial hypertension. The primary outcome is the change in 6-minute walk distance from baseline to week 12.
