About this study

Official title: A Multicenter, Randomized, Parallel Placebo-Controlled Study of the Safety and Efficacy of Subcutaneous Remodulin® Therapy After Transition From Flolan® in Patients With Pulmonary Arterial Hypertension

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.

Read the detailed description

This trial is a multicenter, randomized, parallel placebo-controlled study of Remodulin in patients with pulmonary arterial hypertension with WHO Functional Class II or III clinical status 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 randomized to study drug (1:1 Remodulin: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 be done according to a recommended schedule, which may be modified if necessary according to the patient's clinical status. The dose changes will continue until Flolan therapy has been discontinued and the patient is stable on study drug, or until the patient has met the primary endpoint criteria.

Patients who are transitioned off Flolan, who are stable on study drug, and who have demonstrated the ability to properly self-administer 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. At weeks other than Weeks 1, 4, and 8, the site staff will contact the patient to assess progress and adjust the study drug dose if necessary. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing treprostinil sodium in people with Pulmonary Arterial Hypertension and Pulmonary Hypertension, run by United Therapeutics at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2013.
