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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 community-led environmental management—like removing standing water and properly disposing of waste—can reduce Aedes mosquito populations in Kinshasa. Researchers will compare different mosquito control strategies across 400 households per arm, tracking mosquito numbers and testing for viruses like dengue, chikungunya, Zika, and yellow fever. They will also survey residents' knowledge and practices. The goal is to see if these simple, community-based methods can lower the risk of mosquito-borne diseases in the area.

What this could mean

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

Active substance
Community-based environmental management (cleaning up and removing mosquito breeding sites)
What this could lead to
If effective, this approach could offer a low-cost, community-driven way to reduce Aedes mosquito populations and lower the risk of arboviral diseases in urban Africa.
What could go wrong
This is an early pilot study in one city, so results may not apply elsewhere. Success depends on sustained community participation, and the impact on actual disease cases is not directly measured.

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 2,050 people

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

Started

Mar 2025

Expected to finish

Dec 2026

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.

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
