What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This registry follows adults newly diagnosed with pulmonary arterial hypertension (PAH) who are starting treatment with parenteral treprostinil, a medication given as a continuous infusion under the skin or into a vein. Researchers will collect data from routine care—including dosing, side effects, and how well patients are doing—over at least three years. The goal is to understand how treprostinil is actually used in practice and what outcomes patients experience.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
treprostinil given as a continuous infusion under the skin or into a vein
What this could lead to
If successful, this registry could provide a clearer picture of how treprostinil works in everyday practice, helping doctors optimize treatment for people with PAH.
What could go wrong
This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may be influenced by differences in patient care across centers.
