Purpose

The purpose of the study is to determine if a high dose of Intravenous Immune Globulin (IVIG) plus Standard Medical Treatment (SMT) can reduce all-cause mortality versus SMT alone in hospitalized participants with COVID-19 requiring admission to the ICU through Day 29.

Inclusion Criteria

  • Hospitalized male or female subjects of ≥ 18 years of age at time of Screening who are being treated in the ICU for COVID-19 for not longer than 48 hours or for whom a decision has been made that COVID-19 disease severity warrants ICU admission. - Has laboratory-confirmed novel coronavirus {SARS-CoV-2} infection as determined by qualitative polymerase chain reaction (PCR) (reverse transcriptase [RT]-PCR), or other United States Food and Drug Administration (FDA)-approved diagnostic assay for COVID-19 in any specimen during the current hospital admission prior to randomization. - Illness (symptoms of COVID-19 of any duration requiring ICU level care), and the following: 1. Radiographic infiltrates by imaging (chest X-Ray, computerized tomography (CT) scan, etc.), and 2. Requiring mechanical ventilation and/or supplemental oxygen. - Any one of the following related to COVID-19: i. Ferritin > 400 nanogram per milliliter (ng/mL), ii. Lactate dehydrogenase (LDH) > 300 units per liter (U/L), iii. D-Dimers > reference range, or iv. C-reactive protein (CRP) > 40 milligram per liter (mg/L). - Subject provides informed consent prior to initiation of any study procedures.

Exclusion Criteria

  • Clinical evidence of any significant acute or chronic disease or pathophysiologic manifestations (eg, complications of COVID-19 standard medical treatments) that, in the opinion of the investigator, may place the subject at undue medical risk. - The subject has had a known (documented) serious anaphylactic reaction to blood, any blood-derived or plasma product or a past history of any hypersensitivity reactions to commercial immunoglobulin. - A medical condition in which the infusion of additional fluid is contraindicated. - Shock that is unresponsive to fluid challenge and/or multiple vasopressors and accompanied by multiorgan failure considered by the Principal Investigator not able to be reversed. - Subjects with known (documented) thrombotic complications to polyclonal IVIG therapy in the past. - Subjects with current or prior myocardial infarction, stroke, deep vein thrombosis, or thromboembolic event (within the past 12 months) or who have a history of thromboembolic events of unknown etiology. - Subjects with limitations of therapeutic effort. - Female subjects who are pregnant or of child-bearing potential with a positive test for pregnancy blood or urine human chorionic gonadotropin (HCG)-based assay at Screening/Baseline. - Subjects participating in another interventional clinical trial with investigational medical product or device. - Known history of prothrombin gene mutation 20210, homozygous Factor V Leiden mutations, antithrombin III deficiency, protein C deficiency, protein S deficiency or antiphospholipid syndrome. - Presence of malignancy (either new diagnosis of malignancy or known residual disease) within the past 12 months. - Creatinine at Screening is ≥ 4 mg/dL (or subject is dependent on dialysis/renal replacement therapy). - Known Immunoglobulin A (IgA) deficiency with anti-IgA serum antibodies. - Uncontrolled hypertension at the time of Screening (systolic blood pressure > 200 mm Hg) or refractory severe hypotension with sustained systolic blood pressure < 90 mm Hg unresponsive to vasopressors.

ArmDescriptionAssigned Intervention
Experimental
GAMUNEX-C + Standard Medical Treatment 		Participants received 2 grams per kilogram (g/kg) of GAMUNEX-C, which was capped to a maximum of 160 g infusion intravenously (IV) for participants weighing more than 80 kg on Day 1. The 2 g/kg net total dose was divided either into infusions of 500 mg/kg body weight over 4 days or 400 mg/kg body weight over 5 days as per investigator's decision. Participants received standard of care interventions as per Principal Investigator's discretion from Day 1 up to Day 29.
