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
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 This study
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 Results may not be published yet.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.

Summary

Researchers are testing a field-based sexual health program for people recently exposed to HIV who were notified by New York City's partner services program. The program adds four services to standard contact tracing: HIV and STI testing in the field, same-day start of HIV prevention or treatment medicine, navigation to a sexual health clinic, and support to stay in prevention or HIV care. The trial compares neighborhoods that receive the program at different times to see whether more contacts get tested, start prevention medicine, and connect to ongoing care.

What this could mean

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

Active substance
a field-based sexual health intervention that combines HIV and STI testing, same-day HIV prevention medicine, and clinic navigation
What this could lead to
If it works, health departments could reach people recently exposed to HIV faster and start prevention medicine the same day, which may lower new infections in the hardest-hit neighborhoods.
What could go wrong
The trial tests a public health program, not a new drug, so results depend on whether people accept testing and return for follow-up. Success in New York City neighborhoods may not carry over to other cities or health systems.
