I. Study Design: This is a single-arm feasibility study to assess the safety and efficacy of anti-SARS-CoV-2 convalescent plasma (CP) in 1. intubated, mechanically ventilated patients with confirmed COVID-19 pneumonia by chest X-ray or chest CT. 2. hospitalized patients with acute respiratory symptoms between 3 and 7 days after the onset of symptoms, with COVID-19. II. Study Population: 1. Population 1: Mechanically ventilated intubated COVID-19 patients aged 18 years or older. 2. Population 2: Hospitalized COVID-19 patients aged ≥18 years of age with respiratory symptoms within 3 to 7 days from the beginning of illness. III. Study Agent: SARS-CoV-2 convalescent plasma (1-2 units; ~200-400 mL at neutralization antibody titer >1:160.
There are currently no proven safe and efficacious treatment for COVID-19. While most
patients recover on their own with basic measures at home, around 20% suffer a more
aggressive disease requiring hospitalization, of which 5% necessitating intensive care unit
(ICU) admission and potential invasive breathing support. The wide spectrum of COVID 19 also
include a significant number of totally asymptomatic patients who are unknowingly spreading
the disease. Human convalescent plasma is an option for treatment of COVID-19 and could be
rapidly available when there are sufficient numbers of people who have recovered and can
donate high titer neutralizing immunoglobulin-containing plasma. This convalescent plasma
could be beneficial, not only for severely ill and intubated patients, but also for those
with moderate disease early in their disease course to prevent further disease progression
and ICU admission.
I. Study Design: This is a single-arm feasibility study to assess the safety and efficacy of
anti-SARS-CoV-2 convalescent plasma (CP) in
1. intubated, mechanically ventilated patients with confirmed COVID-19 pneumonia by chest
X-ray or chest CT.
2. hospitalized patients with acute respiratory symptoms between 3 and 7 days after the
onset of symptoms, with COVID-19.
II. Study Population:
1. Population 1: Mechanically ventilated intubated COVID-19 patients aged 18 years or
older.
2. Population 2: Hospitalized COVID-19 patients aged ≥18 years of age with respiratory
symptoms within 3 to 7 days from the beginning of illness.
III. Study Duration: April 3, 2020 to December 31, 2022.
IV. Study Agent:
SARS-CoV-2 convalescent plasma (1-2 units; ~200-400 mL at neutralization antibody titer
>1:160. (Note this is a moving target as assays develop)). Product will be produced using
Blood Bank of New Orleans and safety procedures and procured from patients who have been
symptom free for 14 days and screen negative via NP swab or any other test that emerges in
the meantime. Doors who have been symptoms free for more than 28 days are eligible to donate
without the need of a NP swab. Any emerging FDA guidance will be followed.

Inclusion Criteria:
Population 1: Associated Severe Pulmonary Complications
- 18 years or older.
- Hospitalized and intubated in the ICU with COVID-19 respiratory symptoms and
confirmation via COVID-19 SARS-CoV-2 RT-PCR testing. Patient or proxy is willing and
able to provide written informed consent and comply with all protocol requirements, or
requirement for informed consent is WAIVED due to the inability to communicate with
the patient and unable to identify legally authorized representative.
- Consents to storage of specimens for future testing, or consent waived.
- The requirements to waive a consent are delineated in 21 CFR 50.23 and will be
followed.
- Pregnant and breastfeeding women will not be excluded from the study.
Population 2: Coronavirus Associated Complications in hospitalized patients
- Patients must be 18 years of age or older.
- Hospitalized with COVID-19 respiratory symptoms and confirmation via COVID-19
SARS-CoV-2 RT-PCR testing. Patient is willing and able to provide written informed
consent and comply with all protocol requirements.
- Patient agrees to storage of specimens for future testing.
Exclusion Criteria:
Population 1:
