Clinical Trial Summary

An effective, widely available, and safe treatment that can decrease the duration, severity and fatality of COVID-19 is urgently needed. Also, in the most affected regions the pressure on health care systems including ventilator support capacity can be a limiting factor for survival. Initial studies including from our group indicate that administering convalescent plasma containing high titers of neutralizing antibodies to COVID-19 patients who are already relatively late during the disease course after hospital admission is not effective, which can be explained by high titers of autologous antibodies present in patients. Thus, the antiviral capacity of convalescent plasma is hypothesized to be best positioned early in the disease course and in patients at increased risk for a severe disease course. If effective, any treatment that decreases the need for hospital admission is very valuable but so far, no COVID-19 treatment has been shown to prevent clinical deterioration when given before patients are admitted to the hospital. Primary objective: To evaluate the efficacy, feasibility and safety following the administration of convalescent plasma (ConvP) as a therapy for outpatients diagnosed with COVID-19 at increased risk for an unfavourable clinical outcome and within 7 days after symptom onset. Study design: This trial is a nationwide multicenter, double blind, randomized controlled trial in the Netherlands. Patients will be randomized between the transfusion of 300mL of convP versus regular fresh frozen plasma (FFP). Patient population: Patients with polymerase chain reaction (PCR) confirmed COVID disease with less than 8 days of symptoms, age 70 or older or 50-69 years with at least 1 additional risk factor for severe COVID-19 are eligible. Intervention: 300mL of convP with a minimum level of neutralizing antibodies. A total of 690 patients will be included. Expected duration of accrual: 18-24 months Duration of follow up :Day 28 for the primary endpoint
