E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of this randomised trial is to test whether giving a single infusion of high-dose anti-influenza IVIG (active drug) compared to normal-saline (placebo), to adults hospitalised with influenza A or B, reduces the severity of influenza and hastens full recovery. |
|
E.2.2 | Secondary objectives of the trial |
1) Change from baseline to Day 3 in NEW score. 2) The ordinal primary outcome assessed at Days 1-7, 14 and 28. 3) Number of days hospitalized. 4) Composite of mortality or hospitalization at Days 7, 14 and 28. 5) Requirement for invasive mechanical ventilation or admission to the ICU (among those not enrolled from the ICU). 6) Percent of patients shedding virus at Day 3. 7) Hemagglutination Inhibition (HAI) antibody level changes through Day 7. 8) Grade 3 and 4 adverse events. 9) Serious adverse events. 10) Percent of patients developing bronchitis, pneumonia or other complications
through Day 28. 11) Mortality. 12) Mortality. 13)Complications of influenza such as bronchitis and pneumonia. 14) Percent of patients shedding virus at Day 3. 15) To compare the IVIG and placebo groups for haemagglutination inhibition titre (influenza antibodies) levels at Days 1, 3 and 7. 16) To compare the IVIG and placebo groups for major clinical outcomes in subgroups

3. History of allergic reaction to blood or plasma products (as judged by the site investigator)
4. Known IgA deficiency
5. A pre-existing condition or use of a medication that, in the opinion of the site investigator, may place the individual at a substantially increased risk of thrombosis (e.g., cryoglobulinemia, severe refractory hypertriglyceridemia, or clinically
significant monoclonal gammopathy)
6. Presence of any pre-existing illness that, in the opinion of the site investigator, would place the individual at an unreasonably increased risk through participation in this study
7. Patients who, in the judgment of the site investigator, will be unlikely to comply with the requirements of this protocol
8. Medical conditions for which receipt of a 500 mL volume of intravenous fluid may be dangerous to the patient (e.g., decompensated congestive heart failure)
9. Receiving extracorporeal membrane oxygenation (ECMO)
10. Suspicion that infection is due to an influenza strain or subtype other than A(H1N1)pdm09, H3N2, or influenza B (e.g., H5N1, H7N9) |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is an ordinal outcome at Day 7 that has 6 mutually exclusive categories:
1. death;
2. hospitalization in the intensive care unit (ICU);
3. non-ICU hospitalization, requiring supplemental oxygen;
4. non-ICU hospitalization, not requiring supplemental oxygen;
5. not hospitalized, but unable to resume normal activities; or
6. not hospitalized with full resumption of normal activities. |

visit of the last subject undergoing the trial
|
FLU-IVIG is a randomized, double blind, placebo-controlled, multicenter, international clinical trial. Hospitalized patients with a National Early Warning (NEW) score of 2 or greater will be randomized in a 1:1 allocation to receive either IVIG plus standard of care (SOC) therapy or placebo for IVIG (a comparable volume of normal saline) plus SOC, and will then be followed for 28 days. A total of 320 adult patients will be randomized over multiple influenza seasons. |
