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

Phase 1

• Conditions: COVID-19
• Interventions: Device: Therapeutic plasma exchange

• Registration Number: NCT04592705
• Lead Sponsor: Larkin Community Hospital

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.
