Eliminating Gambiense sleeping sickness using a single-dose oral treatment in screened seropositive people

Official title: An Intervention Study to Evaluate the Impact of Treating gHAT Seropositives Subjects With Acoziborole on Transmission of T.b. Gambiense, and Obtain Further Safety Data on Acoziborole in gHAT Seropositives Individuals.

Run by Institute of Tropical Medicine, Belgium · NCT07789743 · Data updated 2026-11-12

This trial tests whether giving a single dose of acoziborole to people who test positive in screening for Gambiense human African trypanosomiasis can reduce disease transmission over three years.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 11 years or older (≥30 kg) who test positive on CATT or HAT RDT in endemic villages and can ingest oral tablets, with informed consent and compliance for follow-up.

Probably not a fit

Participants who do not test positive or who cannot adhere to follow-up may not receive any clinical benefit from the intervention.

What this trial studies

This interventional Phase 3 trial combines an epidemiological study to see if zero prevalence can be reached with a screen-and-treat approach using acoziborole, and a nested safety study to gather additional safety data in seropositive individuals. Lead coordination is by ITM with DNDi sponsoring the safety component. The study will screen endemic villages, treat seropositive individuals with a single oral dose of acoziborole without parasitological confirmation, and assess cost-effectiveness, diagnostic tests, and transmission outcomes. The primary aim is to determine if this strategy can interrupt transmission within three years and beyond, while monitoring safety in treated participants. The trial leverages a simplified treatment pathway to potentially improve screening uptake and reduce the need for invasive procedures.

Why it matters

Potential benefit: If successful, the approach could simplify field control of gHAT, increase screening uptake, and hasten interruption of transmission.

How similar studies have gone: Prior studies have demonstrated the feasibility of single-dose therapy and test-and-treat concepts, but the transmission-reduction impact in real-world settings remains to be proven.
