Summary

PAX is a prospective, randomized (1:1), double-blind, placebo-controlled study, that have as a objective to evaluate the safety and tolerability of plasma exchange (PE) in patients with Post Acute Covid-19 Syndrome (PCC) comparing to sham plasma exchange. The participants will be randomized in two arms: (1) 6 sessions of PE (Plasma Exchange) with human serum albumin 5% or (2) 6 sessions with placebo (infusion of of sterile saline solution 0.9%) on days 1, 3, 8, 10, 15 and 17.

Detailed description

Randomized participants will receive plasma exchange (PE) or sham PE (placebo) (6 sessions: V2, V3, V4, V5, V6 and V7) and will continue their follow-up visits(V8d22, V9d45, V10d90). Plasma volumes will be replaced, which will vary depending on sex, height, weight and hematocrit.

Conditions

• Post-COVID19 Condition

Interventions

Type	Name	Description
COMBINATION_PRODUCT	Plasma Exchange Procedure	Plasma exchanges will be performed with 5% albumin as the replacement fluid. The typical schedule prescribed will be an exchange of 1 volemia. Blood will be separated into cells and plasma; the cells will be combined with reconstituted 5% human serum albumin and reinfused into the patient with normal saline
OTHER	Sham Plasma Exchange Procedure	For sham plasma exchange procedures, a sound behind the curtain will be performed imitating the sound of the cell processing platform. In these cases, only one infusion of 200 to 250ml of sterile saline solution 0.9% will be performed during the time stablished for all procedures. Albumin will not be necessary for those patients in the Sham plasma exchange arm
