Assessment of Recombinant HAT-RDT Specificity

Plain-language summary
Human African trypanosomiasis HAT, or sleeping sickness, is a tropical disease caused mainly by the parasite Trypanosoma brucei gambiense (gHAT). After a severe epidemic in the 1990s, the World Health Organization (WHO) now targets elimination of transmission of gHAT by the year 2030, which heavily relies on its diagnosis and treatment. Traditional screening tests (like CATT or rapid diagnostic tests (RDTs)) are based on the detection of antibodies against the parasite using native antigens, which are costly and dangerous to produce. New serological tests, using recombinant antigens, have been developed, but little is known about their field performance. The primary objective of this study is to assess the specificity of the newly-developed recombinant RDTs, since it will become very relevant as we move forward towards a screen\&treat strategy. We will also compare the diagnostic accuracy and overall performance of iELISA and molecular testing.

Inclusion Criteria:
* Willing and able to provide written informed consent (and assent for minors 12-17years old)
* Be enrolled in routine HAT screening activities dony by the mobile unit (PNLTHA mobile unit routine active screening teams that visit villages at risk for HAT). People living in the village are targeted for screening.
* Participants must be at least 12 years old
Exclusion Criteria:
* Chilrden younger than 12 years old

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
