Study Testing Convalescent Plasma vs Best Supportive Care

Study Purpose

Currently there are no proven treatment option for COVID-19. Human convalescent plasma is an option for COVID-19 treatment and could be available from people who have recovered and can donate plasma.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Phase 1

Additional Details

Experience from prior outbreaks with other coronaviruses, such as SARS-CoV-1 shows that convalescent plasma contains neutralizing antibodies to the relevant virus. In the case of SARS-CoV-2, the anticipated mechanism of action by which passive antibody therapy would mediate protection is viral neutralization. The only antibody type that is currently available for immediate use is that found in human convalescent plasma. As more individuals contract COVID-19 and recover, the number of potential donors will continue to increase. The investigators seek to treat participants who are sick enough to warrant hospitalization prior to the onset of overwhelming disease.

Arms & Interventions


Experimental: convalescent plasma

This arm will receive convalescent plasma

Placebo Comparator: best supportive care

Oxygen therapy


Biological: - high-titer anti-Sars-CoV-2 plasma

Recipients will receive 1-2 units of ABO matched donor plasma at neutralization antibody titer >1:64 vs best supportive care

Other: - oxygen therapy
