Brief Summary:
This study evaluates the effectiveness of fexinidazole administered to patients with g-HAT at all stages of the disease. The aim of the present study is to provide additional information on the effectiveness and safety of fexinidazole and to assess its use under conditions as close as possible to those in real life, both in patients treated on an out-patient basis and in the hospital setting, depending on clinical status

Condition or disease Intervention/treatment Phase
Trypanosomiasis, African Sleeping Sickness Trypanosomiasis; Gambian Drug: Fexinidazole Phase 3

Arm Intervention/treatment
Experimental: Open label arm
children and adults to receive fexinidazole either as inpatients or outpatients.
Drug: Fexinidazole
Tablets of 600 mg Patients with a weight between 20 and 34kg: 1200mg for 4 days, then 600mg for 6 days Patients with a weight of 35kg and above: 1800mg for 4 days, then 1200mg for 6 days

Primary Outcome Measures :
  1. Outcome (success or failure) [ Time Frame: 18 months follow up ]
    Success is defined as a cure, according to the criteria adapted from the WHO

  2. Outcome (success or failure) [ Time Frame: 12 month follow up ]
    Success is defined as a cure, according to the criteria adapted from the WHO

Secondary Outcome Measures :
  1. Occurrence of grade ≥ 3 adverse events (AEs) including laboratory and haematological abnormalities [ Time Frame: between the first intake of fexinidazole and the end of the observation period or the follow-up period (18 months) for non-serious AEs assessed as related to fexinidazole ]
    AE severity will be graded according to the National Cancer Institute (NCI) Common Toxicity Criteria for AEs (CTCAE), Version 4.03 (13) and, for certain laboratory parameters, modified CTCAE will be used

  2. Occurrence of any serious adverse event (SAE) [ Time Frame: between the first intake of fexinidazole and the end of the follow-up period (18 months) ]
  3. Pharmacokinetic measure to assess patient compliance [ Time Frame: at Day 11 ]
    Presence of fexinidazole and/or its main metabolites in the blood for PK analyses

  4. Outpatients compliance [ Time Frame: at Day 11 ]
    Number of tablets left over and patient's responses to the questionnaire

  5. Outpatients compliance [ Time Frame: at Day 11 ]
    Patient's responses to the questionnaire

  6. Feasibility of self-management of treatment intake in outpatients [ Time Frame: Day 11 ]
    based on interview and left over tablets at D11

  7. questionnaire on acceptability of packaging for outpatients only [ Time Frame: day 0 and day 11 ]
    questionnaire to be completed by patients and caregivers

  8. Whole blood concentration of fexinidazole and its metabolites from dry blood spot of inpatients [ Time Frame: day8, day9, day10, 3hour after treatment administration, Day10, 7h15 after treatment administration, Day10, 24h after treatment administration, Day10, 48h after treatment administration ]
    measured by HPLC/MS/MS Bioanalytical method in all patients treated in hospital
