Brief Summary:
As of 30/03/2020, 715600 people have been infected with COVID-19 worldwide and 35500 people died, essentially due to respiratory distress syndrome (ARDS) complicated in 25% of the with acute renal failure. No specific pharmacological treatment is available yet. The lung lesions are related to both the viral infection and to an intense inflammatory reaction. Because of it's action, as an immunomodulatory agent that can attenuate the inflammatory reaction and also strengthen the antiviral response, it is proposed to evaluate the effectiveness and safety of intravenous immunoglobulin administration (IGIV) in patients developing ARDS post-SARS-CoV2. IGIV modulates immunity, and this effect results in a decrease of pro-inflammatory activity, key factor in the ARDS related to the COVID-19. It should be noted that IGIV is part of the treatments in various diseases such as autoimmune and inflammatory diffuse interstitial lung diseases. In addition, they have been beneficial in the post-influenza ARDS but also have been in 3 cases of post-SARS-CoV2 ARDS. IGIV is a treatment option because it is well tolerated, especially concerning the kidney. These elements encourage a placebo-controlled trial testing the benefit of IGIV in ARDS post-SARS-CoV2.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 146 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: The participant will be randomized to either the group of treatment with IVIG or the placebo group. Participants in the treatment group will receive infusions of polyvalent immunoglobulins for 4 consecutive days. Participants in the placebo group will receive an equivalent volume of sodium chloride 0.9% for the same duration.
Masking: Double (Participant, Care Provider)
Masking Description: The double blinding will be provided by the hospital pharmacy of each establishment with the help of opaque sleeves to mask the product packaging and should be returned to the pharmacy when empty.
Primary Purpose: Treatment
Official Title: Value of Early Treatment With Polyvalent Immunoglobulin in the Management of Acute Respiratory Distress Syndrome Associated With SARS-CoV-2 Infections
Actual Study Start Date : April 11, 2020
Actual Primary Completion Date : November 20, 2020
Actual Study Completion Date : February 20, 2021

Arm Intervention/treatment
Experimental: Intervention - IGIV
Participants in the intervention group will receive a 2g/Kg infusion of human immunoglobulin which should be started before the 96th hours after the start of mechanical ventilation in 4 injections of 0.5 g/Kg over 4 consecutive days.
Drug: Human immunoglobulin
Human immunoglobulin 2g/kg over 4 days (0.5g/kg/d)
Other Name: Clairyg

Placebo Comparator: Placebo
Participants of the placebo group will receive an equivalent volume of sodium chloride 0.9% for the same duration.
Drug: Placebo
Sodium chloride 0.9% in the same volume and over the same time as the immunoglobulin
Other Name: Sodium chloride 0.9%

Primary Outcome Measures :
  1. Ventilator-free days [ Time Frame: 28 days ]

  3. P/F ratio [ Time Frame: Days 1, 3, 7, 14, 21 and 28 ]
    Ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen (FiO2 expressed as a fraction, not a percentage)

  4. Lung compliance [ Time Frame: Days 1, 3, 7, 14, 21 and 28 ]
    Measure of lung compliance

  5. Radiological score [ Time Frame: Days 1, 3, 7, 14, 21 and 28 ]
    Severity scoring of lung oedema on the chest radiograph

  6. Biological efficacy endpoints - C-reactive protein [ Time Frame: Days 1, 3, 7, 14, 21 and 28 ]
    Concentration in mg/L

  7. Biological efficacy endpoints - Procalcitonin [ Time Frame: Days 1, 3, 7, 14, 21 and 28 ]
    Concentration in microgram/L

  8. Immunological profile [ Time Frame: Up to 28 days ]
    Number of CD4 HLA-DR+ and CD38+, CD8 lymphocytes

  9. Number of patients using other treatments for COVID-19 related ARDS [ Time Frame: Up to 28 days ]
    Use of corticosteroids, antiretroviral, chloroquine

  10. Occurrence of deep vein thrombosis or pulmonary embolism [ Time Frame: 28 days ]
    Diagnosis of deep vein thrombosis or pulmonary embolism through imaging exam (eg ultrasound and CT scan)

  11. Total duration of mechanical ventilation, ventilatory weaning and curarisation [ Time Frame: 28 days ]
    Total time of mechanical ventilation, weaning and use of neuromuscular blockade

  12. Kidney Disease: Improving Global Outcomes (KDIGO) score and need for dialysis [ Time Frame: 28 days ]
    Divided in 3 stages, with higher severity of kidney injury in higher stages

  13. Occurrence of adverse event related to immunoglobulins [ Time Frame: 28 days ]
    Kidney failure, hypersensitivity with cutaneous or hemodynamic manifestations, aseptic meningitis, hemolytic anemia, leuko-neutropenia, transfusion related acute lung injury (TRALI)

  14. Occurrence of critical illness neuromyopathy [ Time Frame: Up to 28 days ]
