Evaluation of the Efficacy and Safety of Nano-S1

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the efficacy of the efficacy and safety of investigational drug (NanoS) in patients with mild to moderate COVID-19 at high risk for progression to severe COVID-19, including death.

Detailed Description
-----------------
We conducted a prospective randomized double-blind clinical trial over five months to determine the efficacy of NanoS compared to placebo. The effectiveness of treatment was measured by the significant decline in the number of cases of covid-19 infection and/or a decrease in the viral load determined by SARS-CoV-2 cycle threshold (Ct) value using RT-PCRs test.

| Disappearance of clinical signs | Disappearance of clinical signs (functional and physical) reported and confirmed at the study inclusion visit (Visit 1). The deadline of disappearance: - Less than or equal to 3 days | 3 days | 
| Viral load Ct value | Evaluate the significative decrease of viral load between DAY 0 and DAY 6, and between DAY6 and DAY14 by the variation of CtT values. | admission ,DAY6, DAY14 | 
| Negativation of the RT- PCR | Negativation of the RT- PCR after 14 days since the beginning of the disease. of the randomization | DAY 14 | 
| Tolerance | Évaluate the tolerance of the study product (Nano-S1) versus placebo on the occurrence of adverse events | DAY 14, DAY 30 | 
| Systemic passage | 6. Evaluate the systemic passage of the product of the study by the assay in the blood on J1 (before taking PI ID), on J6 (on the last day) and on DAY 30 in the two study groups. | DAY 30 |
