There is no specific treatment for Ebola Virus Disease (EVD). Current EVD care are supportive, and includes intravenous or oral rehydration, nutrition, pain killers, treatment of coinfections with antibacterial and antimalarial drugs, and blood transfusion when appropriate. Despite these interventions, mortality remains high since the ongoing Ebola outbreak in West Africa was declared in April.
Potential anti-Ebola specific interventions include convalescent plasma, monoclonal and polyclonal antibodies, small inhibitory RNA (siRNA), synthetic adenosine analogues or RNA polymerase inhibitors. All these interventions are considered investigational due to lack of data in humans with EVD.
In this study, the investigators chose to study the efficacy of favipiravir because this drug:
- showed anti-Ebola efficacy in immunodeficient murine models;
- has been studied in thousands of adult humans participating in anti-influenza trials, with good tolerance; it has been approved for treating novel or resistant influenza infections in Japan;
- is immediately available;
- can be used orally, and can be easily given in both adults and children because pills can be crushed and mixed in food or liquids;
- has recently been used in Europe for treating several patients with EVD; the French drug safety agency (ANSM) has reviewed published data as well as data provided by the firm (Toyama Chemical Co., Ltd), and approved its compassionate use in EVD.
Here the investigators propose to assess the efficacy of high-dosed favipiravir in reducing mortality in humans with EVD.
In the present trial "JIKI" (means "Hope" in "Kissi" language), investigators, sponsor, scientific advisory board and safety monitoring board will be coordinated in a very reactive way, so that any new fact can be discussed rapidly and the research plan can be adapted accordingly (change in drug dosage; use of drug combination; combination with another strategy such as passive immunization with convalescent plasma, etc.).

- Mortality [ Time Frame: Day-14 ]Day-0 is the day of the first dose of favipiravir
- Evolution of EBOV plasma RNA and infectious loads [ Time Frame: routine care venepuncture (Day-0; end of symptoms (EOS)+72h and EOS+96h if EOS >Day-9; or Day-12 and Day-13 if EOS <Day-9); (ii) additional trial venepuncture at: Day-2, Day-4 and Day-30 in group A1; Day-2 and Day-30 in group A2 ]
- Occurrence of grade 3 or 4 clinical or biological adverse events (Common Terminology Criteria for Adverse Events, CTAE, v3.0) [ Time Frame: participants will be followed for the duration of hospital stay up to Day-14 ]
- Evolution of viral micro-diversity of EBOV (including potential resistance mutations) [ Time Frame: routine care venepuncture (Day-0; end of symptoms (EOS)+72h and EOS+96h if EOS >Day-9; or Day-12 and Day-13 if EOS <Day-9); (ii) additional trial venepuncture at: Day-2, Day-4 and Day-30 in group A1; Day-2 and Day-30 in group A2 ]
