Mechanisms and Treatment of Chronic Allograft Injury (CAI) Due to Calcineurin Inhibitor (CNI) Toxicity

September 17, 2018 updated by: Enver Akalin, Montefiore Medical Center
The purpose of this study is to find out how well the current drug regimen (including low Prograf dose and Myfortic, which is usually recommended to prevent any further deterioration in the kidney function) works and how safe it is when compared to a combination of Zortress and Myfortic in patients with chronic kidney injury associated with Prograf or Neoral use.

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

Specific Aim 1: To investigate allograft and peripheral blood cell gene expression patterns of patients with CAI by using Affymetrix microarrays.

Hypothesis 1: Gene expression patterns of patients with biopsy findings suggesting calcineurin inhibitor (CNI) toxicity without significant tubulointerstitial infiltrates or transplant glomerulopathy might demonstrate upregulation of genes related to tissue injury, fibrosis, and extracellular matrix deposition without upregulation of genes related to alloimmune response, such as, T and/or B lymphocyte activation markers, surface receptors, co-stimulation molecules, adhesion molecules, cytokines, and chemokines comparing to patients with significant tubulointerstitial infiltrates and/or transplant glomerulopathy that might show upregulation of genes related to alloimmune response, such as, T and/or B lymphocyte activation markers, surface receptors, co-stimulation molecules, adhesion molecules, cytokines, and chemokines.

Specific Aim 2: The effect of everolimus (Zortress)/ mycophenolate sodium (EC-MPS, myfortic®) treatment on allograft and peripheral gene expression patterns.

Hypothesis 2: Everolimus (Zortress) and mycophenolate sodium (EC-MPS, myfortic®) treatment attenuates the progression of CAI due to CNI toxicity by downregulating the expression of genes related to fibrosis, such as, transforming growth factor-β, thrombospondin 1, and platelet derived growth factor-C.

Specific Aim 3: To document the clinical outcomes of everolimus (Zortress) and mycophenolate sodium (EC-MPS, myfortic®) in patients with CAI due to CNI toxicity Hypothesis 3: Everolimus (Zortress) and mycophenolate sodium (EC-MPS, myfortic®) can attenuate the progression of CAI due to CNI toxicity and may improve the creatinine clearance.

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.
