Minimizing Immunosuppression in Old for Old Kidney Transplantation (ESP-CNI)

June 2, 2009 updated by: University of Luebeck

Prospective Randomized Controlled Trial to Compare a Calcineurin Inhibitor Free Immunosuppression With a Low Dose Tacrolimus Based Immunosuppression in "Old for Old" Kidney Transplantation.

Kidney transplantation in the elderly is a challenge since patient's co-morbidity and the decreased injury threshold of older grafts may limit the benefits of transplantation in these patients. To compare favourable effects between low dose tacrolimus (LD-Tac) and mycophenolate-mofetil (MMF) in this patient population the investigators conducted a one year prospective multicenter randomized controlled trial. 90 kidney transplant recipients > 65 years with cadaveric grafts (> 65 years) from 5 centers were enrolled and received baseline immunosuppression with daclizumab induction (1 mg/kg) at day one and day 14, LD-Tac (trough level 5-8 µg/ml), MMF (1-2 g/d) and steroids. After three months, patients were centrally randomized either to MMF (1-2 g/d) and steroids (23 patients) or to LD-Tac and steroids. Follow-up visits were performed every 4 weeks up to one year. Protocol biopsies were performed after one year. The investigators' primary hypothesis is that the biopsy proven rejection rate in the MMF group is not significantly different compared to the LD-Tac group after one year. The investigators' secondary hypothesis is that graft function in the MMF group (reflected by the glomerular filtration rate and protocol biopsy result) is superior to the graft function in the LD-Tac group.

Study Overview

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.
90

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

65 years and older (OLDER_ADULT)

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
Time Frame

Time Frame: One year
One year

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.
