Mesenchymal Stem Cell Transplantation in the Treatment of Chronic Antibody Mediated Kidney Graft Rejection (ABMR)

July 24, 2019 updated by: Veceric-Haler Zeljka, University Medical Centre Ljubljana

Autologous Mesenchymal Stem Cell Transplantation in the Treatment of Chronic Antibody Mediated Kidney Graft Rejection (ABMR)

Transplant rejection is one of the biggest limitations in renal transplant procedures, where the kidney can undergo an acute, late acute, or chronic transplant rejection. With the advancement in transplantation protocols, acute survival of renal transplants has improved, but long-term survival is still unsatisfactory, as most of the renal transplants develop chronic graft rejection. Unfortunately, there is little the investigators know when it comes to improving long-term survival of renal transplants. Mesenchymal stem cells (MSC) have been shown to have immunosuppressive and repairing properties. The purpose of this study is to find out whether MSC in combination with standard therapy of antibody mediated rejection (ABMR) are more effective in preventing organ deterioration and maintaining kidney function.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

Participants will be assigned to receive the full immunosuppressive therapy indicated to treat chronic ABMR (including plasmapheresis (PF) 7x, intravenous immune globulins 100 mg/kg 7x, corticosteroid) and MSC infusions (2x106cells/kg bw after PF) (Group 1) and be compared to historic controls according to "propensity score matching" (treated with immunosuppressive therapy alone (Group 2)). Patients will undergo MSC infusions at the start of the study after each PF. One year post- infusions, patients will be evaluated and undergo kidney biopsies. Blood collection will occur at regular intervals, serum creatinine and the estimated creatinine clearance will be monthly recorded. The transplanted kidney function and morphology (US Doppler) will be evaluated.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
4

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety of MSC transplantation as assessed by adverse events according to CTCAE Version 5Estimated glomerular filtration rate (eGFR)
Time Frame: 12 months
Adverse events according to CTCAE Version 5
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Estimated glomerular filtration rate (eGFR)
Time Frame: 12 months
