Study Overview

Brief Summary

Over the last 40 years, corticosteroids (steroids) have been an important part of drug regimens used to prevent organ rejection and to maintain the immune health of individuals who have received organ transplants. Unfortunately, the negative physical effects of steroids can be severe, especially in children. The purpose of this study is to determine the safety and effectiveness of a steroid-free treatment regimen for children and adolescents who have received kidney (renal) transplants.

Detailed Description

Corticosteroids (steroids) have been a cornerstone of immunosuppressive therapy for kidney (renal) transplantation for over 40 years. However, poor growth and bone loss caused by the use of steroids are devastating to pediatric kidney recipients. The negative physical implications of steroid use also greatly impacts patients' compliance to their prescribed steroid-containing regimens.

The development of a steroid-free regimen for post-transplant pediatric patients is sorely needed. This study will evaluate the safety and efficacy of a steroid-free based treatment regimen in children and adolescents who have received kidney transplants, compared to a standard of care steroid-based regimen. Participants in this study will be pediatric patients with end-stage kidney disease who will undergo kidney transplantation at the start of the study.

Patients will participate in this study for 3 years. Participants will be randomized (1:1) to one of two groups. The study includes 23 study visits over 3 years. A physical exam, medication history, adverse events reporting, blood pressure readings, growth assessment, and blood collection will occur at most visits. At the time of transplantation, participants will have a kidney biopsy. Participants will also undergo cataract screening within 4 months of transplantation.

Outcomes

Primary Outcomes

The Difference in Linear Growth by Treatment Assignment at 1 Year Post Kidney Transplantation

Time Frame: One year post kidney transplantation procedure

Standardized Z-scores were computed following a formula using an age- and gender-specific calculation provided by the NHANES III 2000 Growth Data set. The Z-score system expresses anthropometric values of height as several standard deviations (SDs) below (e.g., a negative value) or above (a positive value) the reference mean or median value. In this study the measure was used to test whether there is a difference in the change in height between the treatment groups: Steroid-Based versus Steroid-Free

Comparison by Treatment Assignment in the Number of Biopsy-Proven Acute Rejections Within 12 Months Post Kidney Transplantation

Time Frame: Up to one year post kidney transplantation procedure

Biopsy-proven acute renal (kidney) rejection \[1, 2\]. 1. Diagnosis of acute rejection was made by renal biopsy using the Banff 97 criteria. The Banff 97 diagnostic category for renal allograft biopsies is an international standardized histopathological classification. Acute rejection is defined by a renal biopsy demonstrating a Banff 97 classification of Grade IA or greater, with higher scores indicating more severe rejection\[2\] 2. Ref: Racusen LC et al.
