Effect of BM-MSCs on Chronic AMR After Kidney Transplantation

September 28, 2015 updated by: Changxi Wang, First Affiliated Hospital, Sun Yat-Sen University

Efficacy and Safety of Bone Marrow-derived Mesenchymal Stem Cells (BM-MSCs) on Chronic Antibody-mediated Rejection (cAMR) After Kidney Transplantation: A Multi-center Perspective Study

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 61 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: MSCs group
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.
