About this study

II. Obtain additional safety information on continuous infusion epoprostenol. III. Obtain additional information on economic resource health consumption.
Read the detailed description
PROTOCOL OUTLINE: Patients are treated with a chronic continuous infusion of epoprostenol.
The highest tolerated infusion rate is determined for each patient by gradually increasing the rate until the target dose is reached or the patient experiences at least 1 dose-limiting effect.
Patients are subsequently treated with a chronic continuous infusion, beginning at a rate below the highest tolerated rate. Attempts are made to increase the dose to the highest tolerated rate over the first 72 hours.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing epoprostenol in people with Hypertension, Pulmonary, run by National Center for Research Resources (NCRR).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
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 24 Jun 2005.
