Study summary

Human African Trypanosomiasis (HAT), or sleeping sickness, is one of the parasitic diseases targeted for interruption of transmission by 2030 by the WHO. The development of fexinidazole as treatment is a huge step towards this achievement; however, the diagnostic algorithm remains complex due to limited sensitivity and specificity of the available tests. A combination of serological screening and confirmation of infection through parasite visualization remains the preferred strategy, although it can be difficult to ensure its full performance in areas that are hard to reach or have limited access to electricity and other means.

The present study would like to test an approach of ensuring treatment with fexinidazole of sero-suspects without confirmation of disease, among patients that consult fixed health infrastructures in the provinces of Maniema, Lomami and Tanganyika. This should enable access to gHAT treatment for patients living in hard to reach areas, actively seeking health care.

Read the detailed description

In this study, all gHAT suspects that attend participating health facilities with suggestive symptoms and test positive in an antibody detection rapid test, will presumptively be treated with fexinidazole. Blood samples will be collected for the post-hoc confirmation of the infection. Nine Health facilities have been selected in the health zones of Kasongo, Kibombo, Kunda and Samba (province of Maniema), Kongolo (province of Tanganyika) and Lubao (province of Lomami) by the PNLTHA, and ITM, based on both epidemiological data and operational considerations.

All patients that consult the selected facilities showing any symptom that could be attributed to gHAT will be offered to participate in the study and kindly requested to provide informed consent. Participants will be tested using the rapid diagnostic test (RDT) HAT Sero-K-SeT. All positive individuals will be asked to provide a venous blood sample, that will be sent to the Institut National de Recherche Biomédical (INRB) or Centre de Recherche en Santé de Kimpese (CRSK) for further serological testing with iELISA and/or immune trypanolysis (TL) and to confirm diagnosis with molecular testing. They will also be offered a 10-day fexinidazole treatment, as inpatient. After treatment, the study participants will be asked to return to the health facility after six months for a clinical follow-up.

Two follow -up visits (3 and 6 months) will be actively organized for all patients with a positive result in iELISA and/or molecular tests conducted at INRB/Kimpese laboratory, through active tracing by health facilities and community members. At the 3 month visit, a clinical examination and DNA/RNA sampling for molecular testing will be performed. At the 6 month visit, adverse events and disease status will be assessed based on clinical signs or symptoms. After the 6-month visit, all patients with a confirmed gHAT infection will be invited to come back to health facility 12, 18 and 24 months after treatment, following WHO guidelines, to confirm cure.

Study population

9 health facilities in the endemic health zones of Kasongo, Kikombo, Kunda and Samba in the province of Maniema, Kongolo in the province of Tanganyika and Lubao in the province of Lomami are selected based on reported HAT cases 3 years prior, where fexinidazole treatment has been provided through PNLTHA or DNDi and where sample transport will be ensured by the NGO SANRU, despite difficult accessibility.

The study aims to include every person that attends the participating fixed healthcare facilitie with suggestive symptoms of gHAT (see above) and is willing to provide informed consent. Since the feasibility of this approach is being tested, as many participants as possible will be included from the pool of people that attend participating healthcare centers during the study period.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Show any suggestive symptoms of gHAT, such as headache (>14 days), long-term fever unless other obvious cause(s), malaise, weakness, arthralgia, facial edema, pruritus, lymphadenopathy, weight loss, mental confussion, abnormal behavior, logorrhea, speech impairment, anxiety, tremor, motor weakness, ataxia, abnormal gait, abnormal movements or seizures;
  • Being older than 6 years old and weighing at least 20 kg;
  • Willing and able to provide written (assent for minors);
  • Minors (6 to 17 years old) willing and able to provide a written assent, after obtaining written informed consent from their parents.

Exclusion criteria

Exclusion Criteria:

  • Being younger than 6 years old or weighing less than 20 kg;
  • Refusal to provide ;
  • Previously treated for HAT (questionnaire to patients and/or family members);
  • Pregnant women.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • People with symptoms attributable to gHAT

    The study will include any person that attends any of the participating healthcare facilities with symptoms that could be attributed to gHAT (long-term fever (unless other obvious causes), headache for a long period (more than 14 days), presence of enlarged lymph nodes in the neck, severe weight loss, weakness, pruritus, amenorrhea, abortions or sterility, psychiatric problems (aggressiveness, apathy, mental confusion, anxiety), sleep disturbances, motor weakness, logorrhea, speech impairment, ataxia, abnormal gait, abnormal movements or seizures) and accepts to participate.

    Other: Screen&treat

Interventions

  • OtherScreen&treat

    Study participants will be tested with an RDT to prove the presence of antibodies against Trypanosoma brucei gambiense. Should the RDT be positive, they will be offered the 10-day treatment with fexinidazole, and an additional blood sample will be taken for the post hoc confirmation of the disease.

What researchers measure

Primary outcomes

  1. Assess the feasibility of an alternative operational approach for the diagnosis and treatment of gHAT patients in areas with limited access and diagnostic capacities.

    This qualitative study will assess: * Number of people with suggestive symptoms; * Number of participants that test positive in the rapid diagnostic test; * Number of sero-positive individuals who accept fexinidazole treatment and * Number of treated individuals who test positive in further serological/molecular tests.

    Time frame: 11 months

Secondary outcomes

  1. Assess gHAT transmission in the provinces of Maniema, Tanganyka and partially Lomami.

    Based on the number of sero-positive individuals and confirmed infections, calculate gHAT incidence in the study areas.

    Time frame: 11 months

  2. Contribute to the collection of evidence of the use of fexinidazole.

    The frequency and severity of any adverse effect due to the fexinidazole treatment will be recorded by a healthcare professional during the 10-day regime as well as in the 6-month follow-up visit.

    Time frame: 11 months.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 2, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
