Criteria

Inclusion Criteria

Patients who meet all of the following criteria will be eligible to participate in the study:

1. Age ≥18 years;

2. Must have laboratory confirmed COVID-19;

3. Must have moderate or severe, immediately life-threatening COVID-19 or Influenza (A or B), as follows:

a. COVID-19 patients with ARDS (Berlin Criteria) as demonstrated by:

i. Chest radiograph or CT scan showing bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules;

ii. Respiratory failure not fully explained by cardiac failure or fluid overload; and

iii. Impaired oxygenation defined as Moderate (partial pressure of oxygen [PaO2]:fraction of inspired oxygen [FiO2] ratio 100 mm Hg to <200 mm Hg with positive end-expiratory airway pressure [PEEP] >5 cm H2O) or Severe (PaO2:FiO2 ratio <100 mm Hg with PEEP>5 cm H2O) on more than 2 arterial blood gases at least 6 hours apart within a 24 hour period;

b. Influenza (A or B) patients with ARDS (Berlin Criteria) as demonstrated by:

i. Chest radiograph or CT scan showing bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules;

ii. Respiratory failure not fully explained by cardiac failure or fluid overload; and

iii. Impaired oxygenation defined as Severe (PaO2:FiO2 ratio<100 mm Hg with PEEP >5 cm H2O) on more than 2 arterial blood gases at least 6 hours apart within a 24 hour period;

4. Requires invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO) despite standard of care rescue measures (eg, prone positioning, and/or PEEP ladder, and/or inhaled pulmonary vasodilators, and/or recruitment maneuvers and/or neuromuscular blockade);

5. Females of childbearing potential must have a negative serum pregnancy test at screening;

6. Females of childbearing potential and nonsterile males must agree to use medically effective methods of contraception from the time of informed consent through 1 month after study drug infusion; and

7. Capable of providing informed consent, or if not capable, a legally authorized representative is capable of providing informed consent

Exclusion Criteria

Patients who meet any of the following criteria will be excluded from participation in the study:

1. Moribund patient who, in the opinion of the Investigator, is not expected to survive at least 24 hours;

2. Known hypersensitivity or allergy to the study drug or any of its excipients;

3. D-dimer level >3 times above normal range;

4. Known gastric or duodenal ulcer;

5. Uncontrolled type 1 or type 2 diabetes, per judgment of the Investigator;

6. Active and untreated bacterial, fungal, parasitic, or viral infection other than COVID-19 or Influenza (A or B). Patients with a history of a positive hepatitis B surface antigen and/or hepatitis B core antibody must have a negative hepatitis B polymerase chain reaction (PCR) assay result. Patients with history of a positive hepatitis C virus antibody test must have a negative hepatitis C PCR assay result;

7. Positive testing for tuberculosis during screening;

8. Known to have received a live vaccine within the previous 1 month;

9. Immunocompromised patients, defined as those who have received a bone marrow or solid organ transplant on immunosuppressive therapy; or history of human immunodeficiency virus (HIV) infection who have not been taking anti retroviral therapy for at least 6 months before enrollment and/or with most recent CD4 count <200 cells/mL and/or most recent detectable viral load within the previous 6 months;

10. Moderate to End-stage liver disease (Childs-Pugh Score >10);

11. Dialysis-dependent due to underlying chronic renal disease. Note: patients who require dialysis for treatment of renal failure due to complications of COVID-19 or Influenza (A or B) infection are not excluded from enrollment;

12. Significant cardiovascular disease (eg, myocardial infarction, arterial thromboembolism, cerebrovascular thromboembolism) within 3 months prior to the start of AVM0703 administration, including: angina requiring therapy, symptomatic peripheral vascular disease, New York Heart Association Class III or IV congestive heart failure, left ventricular ejection fraction <30%, left ventricular fractional shortening <20%, or uncontrolled Grade 3 hypertension (diastolic blood pressure [DBP] >100 mm Hg or systolic blood pressure [SBP] >150 mm Hg) despite antihypertensive therapy.

Note: patients with heart failure requiring medical support due solely to complications of COVID-19 infection are not excluded from enrollment;

13. Significant screening 12-lead ECG abnormalities, including unstable cardiac arrhythmia requiring medication, atrial fibrillation/flutter, left bundle-branch block, second degree atrioventricular (AV) block type 2, third-degree AV block, Grade 2 bradycardia, or heart rate corrected QT interval using Fridericia's formula average of triplicate ECGs >450 ms;

14. Manic-depressive disorder, schizophrenia, or a history of severe depression or substance abuse;

15. Pregnant or breastfeeding;

16. Concurrent enrollment in any other clinical study involving administration of a novel (ie, unapproved or not considered standard of care) investigational pharmacological agent(s). Concurrent enrollment in observational and device studies and studies involving administration of pharmacological agent(s) approved for other indications or considered emerging standard of care for treatment of COVID-19 (eg, hydroxychloroquine, remdesivir, low-dose dexamethasone), will be allowed if approved by the Sponsor;

17. Treatment with standard of care or off-label treatments for COVID-19 (eg, remdesivir), not administered as part of a formal clinical study, where the first dose was initiated within 72 hours of study drug start; and

18. Inability to obtain informed consent from the patient or legally authorized representative.
