E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective is to assess the efficacy of the two new antiviral drugs (etilefrine and diltiazem), compared to placebo, to increase the rate of alive patient with influenza A virus disappearance at 7 days in patients with influenza A virus infection treated by oseltamivir. |
L’objectif principal est de déterminer la capacité de deux molecules repositionnées comme anti-viraux (etilefrine et diltiazem), vs placebo, à augmenter le taux de patients survivants avec une disparition du virus influenza A à 7 jours, chez des patients infectés par ce virus et traités par oseltamivir. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are : 1) to determine the impact of the two new antiviral drugs, compared to placebo, on : - Delay needed for the negativation of influenza A detection. - Overall mortality at day 28 - Length of mechanical ventilation. - Change in PaO2/FiO2 during the treatment period - Length of hospitalization. - Length of ECMO if implemented. 2) to compare between the two new antiviral drugs the primary, and secondary outcomes. 3) to evaluate the in vivo transcriptomic signature under treatment, for the validation of the concept of transcriptomic profile inversion. |
Les objectifs secondaires sont : 1) de déterminer l’impact de ces deux nouvelles molécules antivirales, vs placebo, sur : - le délai necessaire à la négativation de la détection du virus Influenza A. - La mortalité globale à J28. - La durée de ventilation mécanique. - La variation du rapport PaO2/FiO2 durant la durée de traitement. - La durée d’hospitalisation. - La durée d’ECMO si il a été nécessaire d’en implanter une. 2) de comparer entre ces deux nouvelles molécules antivirales les objectifs principal et secondaire. 3) d’évaluer la signature transcriptomique in vivo sous traitement, pour valider le concept d’inversion du profil transcriptomique. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients hospitalized in intensive care units, older than 18 years, - For a severe flu confirmed by positive PCR on nasopharyngeal swab - Whose evolution is less than 96 hours, - The severity of the flu is assessed by a respiratory failure defined by the necessity to resort to mechanical ventilation, invasive or not, or to deliver oxygen with a PaO2/FiO2<200 mmHg. The inclusion is conditioned to the detection of Influenza A viruses by rapid detection kit on nasopharyngeal swab. - Written informed consent from patients or their relatives. |
- Patients hospitalisés en réanimaiton, âgés de plus de 18 ans, - Pour une grippe grave confirmée par une PCR positive sur un écouvillon nasopharyngé - Evoluant depuis moins de 96 heures, - La gravité de la grippe est déterminée par la presence d’une détresse respiratoire définie par la nécessité de recourir à la ventilation mécanique, invasive ou non invasive, pour délivrer de l’oxygène, avec un rapport PaO2/FiO2<200 mmHg. L’inclusion est conditionnée par la détection du virus Influenza A par un test de diagnostic rapide sur écouvillon nasopharyngé. - Consentement éclairé écrit donné par le patient ou l’un de ses représentants. |
