NCT06534450

Brief Summary

The goal of this clinical trial is to assure the safety of long term therapeutic plasma exchange (TPE) with and without Intravenous Immunoglobulin (IVIG) and its effects on biomarkers and epigenetic biologic clocks in forty individuals. The main question is to assure the safety from long term TPE using changes in clinical and laboratory outcomes and also evaluating changes on additional blood biomarkers and epigenetic clocks during and after TPE treatment. Researchers will compare the TPE treatment group to the Sham treatment group to identify changes due to TPE. Participants will receive six TPE or Sham treatments over one of two treatment schedules and may receive IVIG with treatment.

Study Arms (4)

TPE Monthly

ACTIVE COMPARATOR

will receive 6 monthly TPE procedures (TOTAL 6 treatments)

Device: Therapeutic Plasma Exchange

TPE Bimonthly

ACTIVE COMPARATOR

will receive 2 TPE procedures in one week. The same treatment will be repeated on a monthly basis two more times (Two treatments per month for three months to total 6 treatments)

Device: Therapeutic Plasma Exchange

TPE Bimonthly with IVIG

ACTIVE COMPARATOR

will receive 2 TPE procedures followed by 2 gm of IVIG in one week. The same treatment will be repeated on a monthly basis twice more. (Two TPE procedures per month for three months - total of 6 treatments)

Device: Therapeutic Plasma ExchangeDrug: IVIG

Sham

SHAM COMPARATOR

Sham TPE PROCEDURE once a month for 6 months (total of 6 treatments)

Device: Sham

Interventions

ShamDEVICE

The patient's blood will not circulate through the apheresis machine. The patient will receive approximately 250 cc of normal saline during each sham pheresis procedure.

Sham

Blood is withdrawn from a peripheral or central vein into the blood cell separator which separates the whole blood into plasma and cell components. The plasma is removed and the blood cells are returned to the patient along with replacement fluids, most commonly 5% human albumin in normal saline.
