About

The purpose of this study is to evaluate the safety of mesenchymal stromal cells (MSCs) obtained from umbilical cords for the treatment of adults with active systemic lupus erythematosus (SLE).

Full description

This open label trial will evaluate the safety of allogeneic MSCs for the treatment of adults with moderate to severely active systemic lupus erythematosus (SLE). MSCs will be derived from healthy donor umbilical cord cells and 1 dose of MSCs will be tested. MUSC has a good manufacturing practice (GMP) quality Clean Cell Facility to ensure the quality and safety of the MSCs prior to infusing into study participants. The goal of this study is to determine the safety of MSC infusion in patients with SLE when added to standard of care for SLE.

The MSCs used in this trial are cells that are obtained from the umbilical cords of healthy donors having an elective Caesarean section and who have been screened to be sure that they are free of any infectious diseases. These investigational cells will be collected and processed so that they can be used as an infusion treatment. An infusion is when a drug (in this case the MSCs) is administered directly into the blood stream via a vein, usually located in the arm or hand. All participants will receive standard of care and their safety will be monitored throughout the study.

Inclusion criteria

• Patients between 18 and 65 years old, male or female, of any race
• Definite SLE by meeting either SLICC or ACR Classification Criteria for SLE
• Evidence of a positive ANA (≥1:80 titer) or positive dsDNA antibody test within 6 months of screening
• Clinically mild to moderately active SLE determined by SLEDAI score ≥4 and ≤10 at screening, despite SOC therapy
• If the patient has BILAG A or two BILAG Bs in the renal organ system, he/she must have completed at least 6 months of therapy with either mycophenolate mofetil or cyclophosphamide for the current episode of nephritis
• Able and willing to give written informed consent

Exclusion criteria

• Active CNS lupus affecting mental status
• Active lupus nephritis requiring dialysis
• Laboratory exclusions: eGFR <30, WBC <2.0/mm3, hemoglobin <8 g/dL, platelet count <30,000/mm3, liver enzymes AST or ALT >4 times upper limit normal; Positive testing for HIV, hepatitis B or hepatitis C

• History of renal transplantation
• Herpes zoster within the past 90 days or any infection requiring hospitalization or intravenous antibiotics within the past 60 days
• Clinically significant EKG or chest X-ray abnormalities

Description:

Participants will receive a single IV infusion of Mesenchymal Stem Cells (MSCs) 1 x 10\^6 cells/kg in Plasma-Lyte A solution. All participants will receive the infusion at the Baseline (Day 0) visit. All participants will continue on their standard-of-care therapy during the trial.
