Convalescent Plasma in the Early Treatment of High-Risk Patients With SARS-CoV-2 (COVID-19) Infection

Convalescent Plasma in the Early Treatment of High-Risk Patients With SARS-CoV-2 (COVID-19) Infection

This study proposes to evaluate the therapeutic efficacy, immunologic effects and normalization of laboratory parameters for patients at high risk for mortality when infected by SARS-CoV-2 (COVID-19) when administered one unit (approximately 200 mL) of convalescent plasma administered over a period of one hour. Following administration of the convalescent plasma, physical exam/clinical assessment information is collected daily and routine lab result data is collected every three days.

Following the administration of one unit (approximately 200 mL) of convalescent plasma over one hour, the study proposes to determine the therapeutic efficacy (response rate) of convalescent plasma infusion in patients at high risk for mortality when infected by SARS-CoV-2 (COVID-19) by prevention of progression to severe or life threatening COVID-19 during the current hospitalization as determined by evaluating if the patient experienced the following the following: respiratory rate >30/min, Blood oxygen saturation <93%, partial pressure of arterial oxygen to fraction of inspired oxygen ration <300, or received a medical diagnosis of respiratory failure, septic shock or multiple organ dysfunction/failure. This will be captured from the daily physical exam/clinical assessment done as part of routine care and at discharge.

The study also proposes to determine the immunologic effects of convalescent plasma infusion as measured by serial SARS-CoV-2 Ag levels through RT-PCR measured by CoV PCR collected at enrollment, day 7 and discharge.

Finally, the study intends to measure normalization of laboratory parameters for risk which will be documented every 3 days while the patient is hospitalized until the time that lab value returns to within the institution's normal range.
