Study Details
Study Description
Brief Summary
This is a prospective, multicentric, non comparative study aiming to evaluate the clinical and virological evolution of high-risk patients infected with SARS-CoV-2 treated withtin the framework of a cohort ATU ('Autorisation temporaire d'utilisation') or authorisation for early access (AAP) delivered by the French drug agency (ANSM).

Outcome Measures
Primary Outcome Measures
- Percentage of patients hospitalized (if the patient was outpatient) or whose hospitalization was extended for complications from COVID-19 within 1 month of symtoms' onset. [Month 1]
Secondary Outcome Measures
- Percentage of patients hospitalized whatever the reason [Month 1 and 3]
- Percentage of patients with an WHO score >= 5 [Month 1]
- Percentage of patients staying in an Intensive Care Unit in the month following symptoms' onset [Month 1]
- Percentage of patients who died from COVID-19 complications and any other reason [Month 1]
- Percentage of patients presenting a adverse event and percentage of treatment discontinuation caused by those adverse events [Month 1]
- Time between first symptoms and treatment and the reasons for this delay [Day 0]
- Virological response [Day 7 for ambulatory patients, Day 3, 5 and 7 for hospitalized patients]
Percentage of virological response defined by CT>=31 or negative PCR test +
- Virological criteria linked to the emergence of resistance [from inclusion until a negative PCR test or Ct ≥31 is obtained]
Percentage of patients included developing resistance variants, genotypic and phenotypic characterization of resistance variants
- Percentage of patients with positive anti-N and anti-S serology [Day 0 and Month 3]
- anti-S antibody level [Day 0 and Month 3]
- Flow cytometry cartography of myeloid response [Day 0, 7 and Month 1]
Flow cytometry cartography of myeloid (functional subtypes of monocytes and dendritic cells) response
- Flow cytometry cartography of T-lymphocyte response [Day 0, 7 and Month 1]
Flow cytometry cartography of T-lymphocyte (conventional T-lymphocytes by identifying naïve, memory and effector Th1, Th2, Tfh and Th17 T-lymphocytes, NK and gamma-delta T-lymphocytes, regulatory T-lymphocytes; surface and intracellular markers) response
- Flow cytometry cartography of B-lymphocyte response [Day 0, 7 and Month 1]
Flow cytometry cartography of B-lymphocyte (transitional, naïve, memory T-lymphocyte with or without isotypic switching, plasmablasts) response
- Dosing of a wide range of cytokines and chemokines (IFNalpha, IFNgamma, IL-6, IL-1, IL-8, IL-15, IL-18, IL1-RA, IL-7, IL-10, CXCL10, CXCL13, CCL2 and CCL3) using the Meso Scale Discovery approach [Day 0, 7 and Month 1]
- Clinical and biological predictors (clinical parameters, treatment received, virological criteria (cycle threshold (CT), variants) of the onset of complications from COVID19, hospitalization, death [from inclusion until the end of the follow-up (Month 1 or Month 3)]
Identication of clinical and biological predictors of the onset of complications from COVID19, hospitalization, death by a logistic model or survival model (RMST): the response variable is the occurrence of a complication, hospitalization, death or the average survival at 1 month on these different criteria; the covariates are the parameters at inclusion, the treatment received, the virological criteria (CT, variants) which can be considered as a time-dependent covariate
- Clinical and biological predictive factors (clinical parameters, treatment received, virological criteria (cycle threshold (CT), variants)) linked to the neutralizing serological response: non-response, duration of the response [from inclusion until the end of the follow-up (Month 1 or Month 3)]
Identification of clinical and biological predictive factors (clinical parameters, treatment received, virological criteria (cycle threshold (CT), variants)) linked to the neutralizing serological response: non-response, duration of the response by a logistic model or mixed model for repeated measures
- Clinical and biological predictors (clinical parameters, treatment received, virological criteria) of viral response (viral genotypes, emergence of resistant strains) [from inclusion until the end of the follow-up (Month 1 or Month 3)]
Identification of clinical and biological predictive factors related to the virological response (viral genotypes, emergence of resistant strains) by a logistic model: the response variable is RT-PCR negativation at D7 (or CT≥31), the covariates are the parameters at inclusion, the treatment received, the virological criteria at baseline
