PRIMARY outcome

Timeframe: Up to 28 days

Population: 48 patients with severe or life threatening disease with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection enrolled in the study. 7 patients were excluded from analysis due to receiving plasma with insufficient antibodies.

Mortality within 28 days

PRIMARY outcome

Timeframe: Day 0, Day 3, Day 5, and Day 7

Population: Plasma viral load data was available for 35 out of 41 convalescent plasma recipients on day 0. 22 patients out of 35 had non-detectable levels at Day 0; 25 patients out of 34 had non-detectable levels on Day 3; 20 patients out of 27 had non-detectable levels on Day 5; 20 patients out of 24 had non-detectable levels on Day 7.

Median Viral Load at Day 0, Day 3, Day 5, and Day 7 Plasma Viral Load was measured using a research-use only real-time reverse transcription polymerase chain reaction (rRT -PCR) method which targets two regions of the SARS-CoV-2 N gene using TaqMan chemistry. The limit of detection for this assay is 75 copies/mL (standard curve of 75 copies/mL to 10,000,000 copies/mL of in vitro transcribed RNA prepared from the full SARS-CoV-2 N gene).

PRIMARY outcome

Timeframe: Day 0, Day 3, Day 5, and Day 7

Population: 39 out of 41 patients had blood collected on day 0 (pre-transfusion), and on post-transfusion day 3 (n=36), 5 (n=30), and 7 (n=24) and serum antibody titers was assessed at each time point.

Median Serum Antibody Titers at Day 0, Day 3, Day 5 and Day 7 Serum Antibody titers were measured using chemiluminescent SARS-CoV-2 immunoglobulin G (IgG) assay from Diazyme (Poway, CA) Positive IgG serum value is \> or = 1.0 arbitrary units/mL \[AU/mL\] (linear reportable range for IgG is 0.20 - 100.00 AU/mL)
