• Status: Recruiting
• Trial end date: 2023-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to evaluate the efficacy and safety of mesenchymal stem cells (MSCs) obtained from umbilical cords for the treatment of adults with systemic lupus erythematosus (SLE). The goal of this study is to determine if patients receiving an MSC infusion plus standard of care respond better than patients receiving placebo infusion plus standard of care.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Historical presence of at least 4 of 11 of the ACR Classification Criteria

• Evidence of a positive ANA (≥1:80 titer) or positive dsDNA antibody test within 6 months of screening

• If the patient has a BILAG A or BILAG B score in the renal organ system, he/she must have completed at least 6 months of therapy for the current episode of nephritis prior to Screening. Therapy must include at least 6 months of mycophenolate or at least 3 months of cyclophosphamide followed by mycophenolate or azathioprine
