IVIG/Rituximab vs Rituximab in Kidney Transplant With de Novo Donor-specific Antibodies

October 25, 2022 updated by: Seoul National University Hospital

A Randomized, Open, Controlled Trial of High Dose IVIG/Rituximab Versus Rituximab in Kidney Transplant Patients With de Novo Donor-specific Antibodies

The objective of this study was to compare two strategies of de novo donor specific antibodies (DSA) and antibody-mediated rejection (AMR) prevention in renal transplant recipients: high dose intravenous immunoglobulin (IVIG)/rituximab regimens versus rituximab alone.

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

Although recent advances in immunosuppressive regimens after kidney transplantation (KT) have reduced the incidence and consequences of T-cell-mediated rejection (TCMR) and have improved short-term outcomes, long-term allograft loss attributable to AMR is still responsible for substantial medical and socioeconomic burdens in kidney transplant recipients. Numerous studies have shown that de novo DSA after KT are associated with AMR, which leads to allograft loss. IVIG is a medication that has emerged as a useful tool in modulating immunity, treatment of AMR and in desensitization protocol. Treatment with rituximab or combination of IVIG/rituximab has sought to further diminish antibody production (de novo DSA) in the treatment of AMR. Several studies have been reported, but in the absence of control groups or standardization of treatment, their efficacy is difficult to assess.

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

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
change in delta DSA MFI sum
Time Frame: baseline and 3 months post-treatment, 1 year post-treatment
change of pre- and post-treatment DSA MFI sum, monitoring DSA during follow-up period
baseline and 3 months post-treatment, 1 year post-treatment

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
Change in estimated glomerular filtration rate(eGFR) by CKD-EPI equation
Time Frame: baseline and 3 months post-treatment, 1 year post-treatment
