To assess the efficacy and safety of Human coronavirus immune plasma (HCIP) to reduce the risk of hospitalization or death, the duration of symptoms and duration of nasopharyngeal or oropharyngeal viral shedding.

Official Title

Comparison of the Efficacy and Safety of Human Coronavirus Immune Plasma (HCIP) vs. Control (SARS-CoV-2 Non-immune) Plasma Among Outpatients With Symptomatic COVID-19


The purpose of this randomized, double-blind, controlled, phase 2 trial is to evaluate the efficacy of treatment with HCIP in reducing hospitalization and death prior to hospitalization among outpatient adults who have RNA detection test-confirmed COVID-19 AND have developed any symptoms of COVID-19 including but not limited to fever, cough, or other COVID associated symptoms like anosmia. Ambulatory/outpatient adults subjects 18 years of age or older, regardless of risk factors for severe illness may participate. A total of approximately 1344 eligible subjects stratified with a target goal (but not binding) of 50:50 in the <65 vs ≥ 65 age range will be randomized in a 1:1 ratio to receive either HCIP or control plasma.
