What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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
Cancelled before anyone took part.

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.

When the status isn't known

Summary

This study tests whether a single daily pill containing three blood pressure medications can better control resistant hypertension compared to taking multiple separate drugs. Researchers will enroll 142 adults with high blood pressure that is not well controlled despite using 3 to 5 different medications. Participants will either switch to the triple-combination pill or continue their usual care, and blood pressure will be measured over 24 hours after 12 weeks.

What this could mean

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

Active substance
Triple fixed-dose combination of perindopril, indapamide, and amlodipine
What this could lead to
If successful, this could offer a simpler, more effective way to control resistant hypertension, potentially reducing heart attack and stroke risk.
What could go wrong
This is a small, early-stage trial (142 participants) at a single center, so results may not apply broadly. The open-label design could introduce bias, and the simplified regimen may not work for everyone.

Participants

About 142 people

The number the study aims to enrol. It can still change while the study runs.
