Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This approach is immediately available from individuals who have recovered, are viral free,and can donate immune plasma (IP) containing high titer neutralizing antibodies. Passive antibody therapy can be given to a patient recently exposed or a patient who is developing an infection with COVID-19 by obtaining plasma units from immune individuals by standard plasmapheresis using FDA-approved blood banking procedures, cross matching the unit(s) to the recipients and infusing the unit(s) using standard transfusion procedures for blood products. Based on the safety and long-term experience with plasma infusions, plasma exchanges, and other procedures involving plasma or plasma product, this protocol was designed as a phase II single arm trial that involves the administration of antibodies to a given agent to a susceptible individual for the purpose of preventing or treating an infectious disease due to that agent.
The only antibody formulation that is available for emergent use is that found in convalescent plasma. As more individuals contract COVID-19 and recover, the number of potential donors will increase.
The principle of passive antibody therapy is that it is more effective when used for prophylaxis than for treatment of disease. When used for therapy, antibody is most effective when administered shortly after the onset of symptoms. The reason for temporal variation in efficacy is not well understood but could reflect that passive antibody works by neutralizing the initial inoculum, which is likely to be much smaller than that of established disease. Alternatively, antibodies may dampen the early inflammatory response leaving the infected individual asymptomatic. For example, antibody therapy for pneumococcal pneumonia was most effective when given shortly after the onset of symptoms and was of no benefit if antibody therapy was delayed beyond the third day of disease. For passive antibody therapy to be effective, a sufficient amount of antibody must be infused. The antibody will circulate in the blood, reach tissues,and provide protection against infection. Depending on the type of antibody, amount, and composition, the half-life can vary from weeks to months. It is under these circumstances, the investigators plan to treat patients who are sick enough to be hospitalized before the onset of overwhelming disease involving a systemic inflammatory response, sepsis, and/or ARDS.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Study participants
A total of 29 eligible subjects will be enrolled to receive high titer anti-SARS-CoV-2 plasma. Participants will be compared to a historical control group via retrospective chart review.
High-Titer Anti-SARS-CoV-2 (COVID 19) Convalescent Plasma
Pathogen reduced SARS-CoV-2 convalescent plasma (1-2 units; \~200 mL each for a total of 200-400mls) given preferably in one day, but allowable to be given over 2 days if clinical circumstances delay infusions in 1 day), with titer to be determined after the unit has been infused.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients hospitalized with COVID-19 respiratory symptoms within 72 hours of admission to a"floor" bed (non-ICU bed) and confirmation via SARS-CoV-2 RT-PCR testing.
* Patient and/or surrogate is willing and able to provide written informed consent and comply with all protocol requirements.
* Patients with hematologic malignancies or solid tumors are eligible.
* Patients with autoimmune disorders are eligible.
* Patients with immunodeficiency and organ or stem cell transplant recipients are eligible.
* Patients who have received or are receiving hydroxychloroquine or chloroquine are eligible (but will be taken off the drug)
* Prior use of IVIG is allowed but the investigator should consider the potential for a hypercoagulable state.
Exclusion Criteria
* Patients on other anti-COVID-19 trials being treated with tocilizumab (anti-IL-6 receptor), Siltuximab (anti-IL-2), Remdesivir, or other pharmacological trials that may be initiated hereafter.
* A pre-existing condition or use of a medication that, in the opinion of the site investigator, may place the individual at a substantially increased risk of thrombosis (e.g., cryoglobulinemia, severe refractory hypertriglyceridemia, or clinically significant monoclonal gammopathy).
* Contraindication to transfusion or history of prior reactions to transfusion blood products.
* Medical conditions for which receipt of 500-600 mL of intravenous fluid may be dangerous to the subject (e.g., decompensated congestive heart failure).
