Fexinidazole in Human African Trypanosomiasis Due to T.b. Gambiense at Any Stage

Official Title

An Open-label Study Assessing Effectiveness, Safety and Compliance With Fexinidazole in Patients With Human African Trypanosomiasis Due to T.b. Gambiense at Any Stage

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
