Prednisone Withdrawal Versus Prednisone Maintenance After Kidney Transplant

Randomized, Prospective Single-center Study Comparing a Rapid Discontinuation of Corticosteroids (Steroid Withdrawal) With Corticosteroid Therapy in Kidney Transplantation Using Mycophenolate Mofetil and Tacrolimus Maintenance Therapy

• Status: Terminated
• Phase: Phase 4

• Healthy volunteers: Not accepted

Summary

The purpose of the study was to determine if rapid discontinuation of corticosteroids (also known as prednisone withdrawal) and maintenance immunosuppression with Prograf (tacrolimus) and CellCept (mycophenolate mofetil) while using Thymoglobulin (Rabbit antithymocyte globulin) will give similar safety and efficacy results compared to continuation of corticosteroids (also known as prednisone maintenance) and standard maintenance immunosuppression with Prograf (tacrolimus), CellCept (mycophenolate mofetil) while using Thymoglobulin (Rabbit antithymocyte globulin).

Detailed description

Corticosteroids (one specific type is prednisone) have been used in clinical transplantation for more than 30 years. There are many side effects of corticosteroids including significant bone disease, diabetes (elevated blood sugar levels), fluid retention and hypertension (high blood pressure), psychosis, peptic ulcer disease, hyperlipidemia (elevated lipid levels such as cholesterol and triglycerides), obesity (overweight), acne, and susceptibility to infections. It is hoped that the new generation of potent immunosuppressive medications (such as Prograf and CellCept) will permit avoidance or withdrawal of corticosteroids for the majority of patients to avoid both short- and long-term complications of corticosteroid use in kidney transplant recipients.

Interventions

Type	Name	Description
DRUG	prednisone	In this group, participants had prednisone rapidly decreased until completely eliminated by day 6 after transplant. Participants began on 500mg of intravenous methylprednisolone on the day of transplant, followed by the following doses of oral prednisone: 160mg on day 1, 120mg on day 2, 80mg on day 3, 40mg on day 4, 20mg on day 5, none from day 6-on.
DRUG	rabbit antithymocyte globulin	Participants in both groups received 3 to 5 doses of an intravenous medication to prevent rejection called Thymoglobulin (rabbit antithymocyte globulin) as per our standard of care. This drug was dosed at 1.5 milligrams/killograms per dose and dosing was then based on body weight. The dose was decreased in half or held if the participant had a low white blood cell count or if the participant a low platelet count. The first dose was given intravenously in the operating room and subsequent intravenous doses were administered either while participants were inpatients or outpatients for a total of 3 to 5 doses for a total of up to 6mg/kg. The number of doses was based on transplant kidney function and risk factors for rejection.
DRUG	Tacrolimus	Participants in both groups received tacrolimus per our standard of care. This medication helped to prevent rejection and was initially dosed at 0.1-0.2 milligrams/killograms/day in two divided doses, given orally, based on participant's body weight. We then looked at the trough levels of this medication(the lowest level before the next dose), and aimed to keep the trough level between 5-10 nanograms/milliliter throughout the study.
DRUG	Prednisone	Participants in this group continued on prednisone indefinitely. Participants began with 500mg of intravenous methylprednisolone on the day of transplant, followed by the following doses of oral prednisone: 160mg on day 1, 120mg on day 2, 80mg on day 3, 40mg on day 4, 20 mg days 5-9, 15 mg day 10-19, 10 mg day 20-24, 7.5 mg day 25-29, and 5mg from day 30-on indefinitely.
DRUG	Mycophenolate mofetil	Participants in both groups received mycophenolate mofetil by mouth twice daily indefinitely. Dosing for patients in the Prednisone withdrawal group was 1000mg orally twice daily. The dose was decreased or held at the discretion of the physician, for side effects such as low white blood cell count, or low platelet count, or if the participant experienced stomach side effects such as heartburn, nausea, vomiting or diarrhea.
DRUG	Mycophenolate mofetil	Participants in both groups received mycophenolate mofetil by mouth twice daily indefinitely. Dosing for patients in the Prednisone maintenance group was 500 mg orally twice daily. The dose was decreased or held at the discretion of the physician, for side effects such as low white blood cell count, or low platelet count, or if the participant experienced stomach side effects such as heartburn, nausea, vomiting or diarrhea.
