Aralast NP With Antiviral Treatment and Standard of Care Versus Antiviral Treatment With Standard of Care in Hospitalized Patients With Pneumonia and COVID-19 Infection

A Randomized, Open-Label Study of the Efficacy and Safety of Aralast NP, an Alpha-1 Antitrypsin Infusion Therapy With Antiviral Treatment and Standard of Care Versus Antiviral Treatment With Standard of Care in Hospitalized Patients With Pneumonia and COVID-19 Infection

This is a Randomized, Open-Label Study of the Efficacy and Safety of Aralast NP Infusion Therapy with Antiviral Treatment and standard of care versus Antiviral Treatment and standard of care (control group) in Hospitalized Patients with Pneumonia and COVID-19 Infection.

Approximately 20 subjects in total will be randomized with 1:1 ratio to the high dose of Aralast NP infusion therapy plus antiviral and standard of care versus antiviral therapy and standard of care.

Each subject will participate in the study for 24 days and have one safety follow-up phone call at 30 days. Active treatment will last 17 days, subject will be dosed on Days 1, 3, 5, 7, 9 and have a final booster infusion on Day 17. If the subject is discharged from hospital, any remaining infusions and assessments will be conducted via outpatient clinic visit or home health visit. Subjects will have an in-person visit (hospital or clinic) on Day 24 for a CT scan and follow-up assessment.

Efficacy will be evaluated by measuring the duration of new non-invasive ventilation or high flow oxygen used. Additional endpoints include clinical status, cytokine levels, oxygen requirements, SOFA scores, risk of coagulopathy, need for Vasopressors, mortality during the treatment period, PK samples, average days spent in the hospital/ICU, and number of days without a fever.

Inclusion Criteria

1. Subject will sign and date an informed consent form.
2. Hospitalized subjects will be 18 years of age or older.
3. Lab confirmed positive for COVID-19 within 72 hours prior to randomization.
4. Subjects with COVID-19 with evidence of pneumonia (diagnosed by a chest x-ray) on supplemental oxygen or non-invasive ventilation with PO2/FiO2 ratio less than 300.
5. Subject must have one of the following elevated inflammatory markers: C-reactive protein >40mg/L; D-Dimers > 250ng/mL DDU or >0.5mcg/mL FEU; Ferritin >400ng/mL; LDH >300U/L.

Exclusion Criteria

1. Subject is on mechanical ventilation at time of screening.
2. Subject is not expected to survive greater than 48 hours from screening based on PI judgement.

4. Subject is on immunosuppressive agents, with the exception of corticosteroids for severe COVID-19 patients at the discretion of the PI.
5. Subject is currently participating in a trial for any other investigational drug.
6. Subject is on another plasma derived product or has received plasma or blood products within the last 48 hours.
7. Subject is pregnant or breastfeeding.
8. The subject, or the next of kin/power of attorney are not able to give the proper informed consent.
9. The subject has a known IgA deficiency with anti-IgA antibodies.
10. Subject has a known Alpha-1 Antitrypsin Deficiency.
11. Subject has antibodies against alpha-1 proteinase inhibitor
12. Subject has renal, liver or multisystem organ failure
13. Subject has known history of hypersensitivity following infusions of human blood or blood components (eg, human immunoglobulins or human albumin).
14. Positive serological test for human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
