About this study

Official title: A Comparative Bioavailability Study of UT-15C SR (Treprostinil Diethanolamine, Sustained Release) Oral Tablets and UT-15C (Treprostinil Diethanolamine) Administered as an Oral Solution in Healthy Volunteers

This single center, open label, randomized, two-period, two-sequence cross-over study is designed to evaluate the relative bioavailability of a treprostinil diethanolamine 1 mg tablet in reference to treprostinil diethanolamine 1 mg oral solution (administered as four 0.25 mg doses every 2 hours for a 1 mg total dose) in twenty-four healthy volunteers. Other secondary outcomes of interest include assessment of pharmacokinetic parameters of treprostinil diethanolamine 1 mg tablets and a treprostinil diethanolamine 1 mg oral solution administered as four doses (0.25 mg every 2 hours for a 1 mg total dose) and evaluation of the safety and tolerability of each treatment regimen.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • treprostinil diethanolamineDrug

    Subjects will be administered a 1 mg dose of treprostinil diethanolamine as a single tablet, and treprostinil diethanolamine oral solution 0.25 mg dose every 2 hours for four doses (1 mg total).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma treprostinil concentrations

    Pharmacokinetic blood sampling will occur twice for each subject. Pharmacokinetic parameters will be derived from treprostinil concentration-time data

    Measured: 1 month

Secondary outcomes (1)
  1. vital sign measurements, clinical laboratory parameters, electrocardiograms (ECGs) and adverse events (AEs)

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing treprostinil diethanolamine in people with Pulmonary Arterial Hypertension, run by United Therapeutics at 1 site 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 9 inclusion and 13 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 13 Oct 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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.

What does the primary outcome measure?

Plasma treprostinil concentrations (time frame: 1 month). It is what the study was designed to measure, not a finding.

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 13 Oct 2010.
