NCT02563340

Brief Summary

This study is designed to investigate the efficacy and safety of allogeneic bone marrow-derived mesenchymal stem cells (BM-MSCs) on chronic antibody-mediated rejection (cAMR) after kidney transplantation. Chronic AMR is diagnosed according to Banff criteria 2013 based on renal graft biopsy and donor specific antibodies (DSA) examination. cAMR patients are assigned to MSCs group or control group. Patients in control group are prescribed to current desensitization therapy including at least one of the following treatments: plasmapheresis (PP), intravenous immunoglobulin (IVIG), rituximab or Bortezomib, depending on individual pathological and immunological features (eg. DSA type and titer) of each study subjects. Patients in MSCs group receive additional BM-MSCs therapy besides desensitization treatments as in control group. Allogeneic BM-MSCs (1\*10\^6/kg) are intravenously administered every two weeks for four consecutive doses. All cAMR patients are followed up for one year. Renal function, DSA level, pathological features, patient/graft survival, and severe adverse events are monitored during the follow-up period. Immunological features of patients in both groups are consecutively examined.

Study Arms (2)

MSCs group

EXPERIMENTAL

cAMR patients in this group receive additional intravenous allogeneic BM-MSCs (1\*10\^6/kg) every two weeks for four consecutive doses, besides current desensitization therapy including at least one of the following treatments: plasmapheresis (PP), intravenous immunoglobulin (IVIG), rituximab or Bortezomib.

Other: BM-MSCsOther: Desensitization therapy (PP, IVIG, rituximab or Bortezomib)

Control group

ACTIVE COMPARATOR

cAMR patients in this group receive current desensitization therapy including at least one of the following treatments: plasmapheresis (PP), intravenous immunoglobulin (IVIG), rituximab or Bortezomib.

Other: Desensitization therapy (PP, IVIG, rituximab or Bortezomib)

Interventions

BM-MSCsOTHER

BM-MSCs are from third-party healthy donors, and have no HLA alleles similar to renal allograft donors or reacting to positive anti-HLA antibodies in recipients.

Also known as: allogeneic bone marrow-derived MSCs
MSCs group

At least one drug or treatment is applied as desensitization therapy to decrease DSA, reduce B cells or inhibit plasma cells, depending on individual condition.
