Brief Summary:
The aim of this study is to evaluate the possibility to repropose marketed drugs as antiviral ones, based on their ability to reverse the transcriptomic signature of the infected cells. This strategy has to be considered is the context of emerging viral diseases and of increase of resistance to antivirals. Concerning infection by Influenza viruses, the main drugs were identified and evaluated on in vitro and in vivo models: diltiazem. Therefore, it will be assess the efficacy of these the drug, compared to placebo, to treat severe flu.

Arm Intervention/treatment
Experimental: diltiazem
oseltamivir + diltiazem
Drug: Oseltamivir
150 mg twice a day during 10 days (ANSM guidelines for severe flu).

Drug: Diltiazem
60 mgx3 per day during 10 days.

Placebo Comparator: oseltamivir + placebo
oseltamivir + placebo of diltiazem
Drug: Oseltamivir
150 mg twice a day during 10 days (ANSM guidelines for severe flu).

Drug: Placebos
Placebo of diltiazem

Primary Outcome Measures :
  1. Percentage of alive patients without detection of influenza A virus by RT-PCR in nasopharyngeal swabs, [ Time Frame: 7 days after the beginning of the treatment. ]

Secondary Outcome Measures :
  1. Delay needed for the negativation of influenza A detection by RT-PCR [ Time Frame: up to 10days ]
  2. Overall mortality [ Time Frame: At 28 days ]
  3. Length of mechanical ventilation [ Time Frame: an average of 10 days ]
  4. Change in Oxygenation (PaO2/FiO2 Ratio) [ Time Frame: once day for 10 days and at 28 days ]
    Arterial blood samples for blood gas analysis are collected during the treatment period. The differences in the mean values of PaO2/FiO2 ratio are registered and analysed.

  5. Length of hospitalization [ Time Frame: an average of 10 days in ICU and of 16 days in hospital ]
  6. Length of extracorporeal membrane oxygenation (ECMO) if implemented. [ Time Frame: an average of 10 days ]
  7. Transcriptomic signature determined by the DNA microarray technology and analysed by bioinformatic tools [ Time Frame: Four time points : at inclusion, the first day after inclusion, the fourth day after inclusion, and the seventh day after inclusion ]
    evaluation of the capacity of tested molecules to reverse the transcriptomic signature linked to the viral infection
