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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

This study in Uganda tests whether adding lab tests for common sexually transmitted infections (STIs) to standard HIV risk screening helps more women start and stick with PrEP, a daily pill that prevents HIV. About 4,500 HIV-negative women aged 15-39 will be randomly assigned to either standard screening or standard screening plus STI testing. Researchers will track PrEP use, adherence, and persistence over six months to see if the extra testing makes a difference.

What this could mean

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

Active substance
STI diagnostic testing for chlamydia, gonorrhea, trichomonas, and syphilis
What this could lead to
If it works, this could show that routine STI testing helps identify more women at risk for HIV and encourages them to use PrEP consistently, potentially reducing new HIV infections in Africa.
What could go wrong
This is a large trial, but it's testing a screening strategy, not a new drug. The benefit depends on whether women act on the test results, and results may not apply outside Uganda.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 5,560 people

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

Started

Sep 2025

Expected to finish

Jan 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
