Official Title
Measurement of IL-6 and Secondary Inflammatory Markers Before and After Therapeutic Plasma Exchange (TPE) in Hospitalized Patients
Brief Summary

Given the current lack of an effective drug or therapy, a clinical trial to better understand the safety and efficacy of therapeutic plasma exchange (TPE) in COVID-19 patients is urgently needed. The goal of this trial is to study the efficacy and safety of TPE therapy in subjects with moderate to severe COVID-19 by determining the morbidity and mortality after TPE therapy.

Unknown status
COVID-19

Device: Therapeutic plasma exchange

TPE is the process of plasmapheresis, an invasive procedure separating plasma from red blood cells using centrifuge-based devices.
Filtration involves the insertion of a central venous catheter in the internal jugular, femoral or subclavian vein after which blood is drawn from the patient's circulation and transferred to a filter that separates the plasma from blood cells. Thereafter, the plasma extracted is substituted with human albumin and/or FFP.

Eligibility Criteria

Inclusion Criteria:

1. Patients with moderate-severe COVID-19 infection including early acute lung injury
(ALI)/early acute respiratory distress syndrome (ARDS)

2. Able to provide Informed Consent signed by the subject or by the subject's legal or
healthcare proxy.

3. Admitted to the participating facilities as listed above (Larkin South Miami Hospital,
Larkin Palm Springs Hospital).

4. Subjects between 18 and 69 years of age.

5. If female, subjects that have a negative result in a quantitative b-HCG blood test if
they are within reproductive age.

6. A positive COVID-19 test via nasopharyngeal swab RT-PCR.

7. Agree to not participate in another clinical trial during the study period.

Exclusion Criteria:

1. Under 18 years of age or older than 69 years of age.

2. Severe disease, defined as:

i. dyspnea ii. respiratory frequency ≥ 30/min iii. blood oxygen saturation ≤ 93% iv.
partial pressure of arterial oxygen to fraction of inspired oxygen ratio < 300, and/or
v. lung infiltrates > 50% within 24 to 48 hours;

3. Life-threatening disease, defined as:

i. respiratory failure ii. septic shock, and/or iii. multiple organ dysfunction or
failure

4. Unable to provide informed consent or decline to consent.

5. Sequential Organ Failure Assessment (SOFA) score of 12 or above.

6. Hemodynamic instability, sepsis, or other conditions causing inability to tolerate
fluid shifts

7. Inability to tolerate central line placement

8. Allergy to FFP or albumin

9. Severe hypocalcemia

10. Patients with heparin allergies should not receive heparin as an anticoagulant during
plasmapheresis

11. Patients taking angiotensin-converting enzyme (ACE) inhibitors are advised to stop
taking the medication for at least 24 hours before starting plasmapheresis

12. Active or recent bleeding (unless controlled for >48 hours).

13. Thrombocytopenia (≤25,000/L).

14. Advanced cirrhosis with a history of esophageal varices.

15. Chronic kidney disease requiring hemodialysis.

16. Active solid or non-solid malignancy or Lymphoma within the last 2 years.

17. Heart failure (NYHA class III or IV).

18. HIV infection (AIDS criteria), a history of immunodeficiency, or subject is currently
receiving immunosuppressive therapy.

19. Women of childbearing age who are pregnant or intend to become pregnant during the
study period.

20. Known history of chromosomal or genetic abnormalities.

21. History of hypersensitivity or any kind of adverse reaction to blood products.

22. Contraindication to transfusion of blood products, or refusal due to
religious/personal reasons.

23. Any kind of drug or alcohol dependence that would interfere with adherence to the
study requirements.

24. Already part of this trial, recruited at a different hospital.
