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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a two-drug combination (darunavir/cobicistat plus lamivudine) works as well as a standard three-drug combination (darunavir/cobicistat plus tenofovir alafenamide/emtricitabine) in people with HIV whose virus is already suppressed. The study involves 78 adult men in Mexico who have had undetectable HIV levels for at least 48 weeks. Researchers will compare how well each regimen maintains viral suppression and monitor safety over 24 and 48 weeks.

What this could mean

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

Active substance
Darunavir/Cobicistat plus Lamivudine
What this could lead to
If successful, this could show that a simpler two-drug HIV regimen is as effective as the standard three-drug approach, potentially reducing pill burden and side effects.
What could go wrong
This is a small pilot study with only 78 participants, all men, so results may not apply to everyone. The two-drug regimen might not suppress the virus as well as the three-drug combination.
