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.

Inclusion Criteria: * Participants able to give signed informed consent and assent form for adolescents, which includes willingness to comply with the schedule of follow-up visits and other requirements and restrictions listed in the informed consent form (ICF) and in this protocol * All sexes * 11 years of age or older at the start of the study and weight ≥30 kg at the screening of Part B * Participants who are CATT test or HAT RDT positive (information provided by the mobile team and included into TrypElim (see Part A) * Participants who are able to ingest oral tablets * Participants with known address and/or contact details provided * Participants who are able to comply with the schedule of follow-up visits and other requirements of the study * Participants must agree not take part in any other clinical trials during the participation in part B of this study * Participants of child-bearing potential must be willing to use appropriate contraceptive methods. Exclusion Criteria: * Individuals with a positive parasitological exam on the spot at baseline (mAECT or lymph gland puncture) * Participants previously treated for g-HAT or previously treated because of gHAT seropositive results * Pregnant women * Breast-feeding women * Children ≥11 years, but under 30kg body weight at the screening for part B * Clinically significant medical condition that could, in the opinion of the investigator, jeopardise the subject's safety or participation in the study * Individuals presenting a jaundice at screening * Participants who are taking, or who are expected to need to start within 3 months, a medicine (including traditional or herbal) which may interact with acoziborole and which cannot be stopped or adjusted (please refer to investigator manual or contact DNDi)
