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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study follows 420 adults with HIV whose virus is fully suppressed by medication. Researchers want to see if switching to a different HIV drug regimen causes hidden drug resistance to appear. They will compare people who switch drugs with those who stay on their current treatment, including some with very low levels of virus. The goal is to learn how to make treatment switches safer and more effective over the long term.

What this could mean

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

What this could lead to
If successful, this study could help doctors choose safer and more effective HIV medication switches, reducing the risk of drug resistance.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test a new drug or cure, and results may not apply to all HIV patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
