Steroid Withdrawal in Pediatric Kidney Transplant Recipients

A Double-Blind Randomized Trial of Steroid Withdrawal in Sirolimus- and Cyclosporine-Treated Primary Transplant Recipients

The purpose of this study is to examine the effects of withdrawing steroids on graft rejection and kidney functions in kidney transplant recipients between the ages of 0 and 20 years (prior to their 21st birthday).

Graft survival has improved in recent years in children with kidney transplants. One bad side effect of steroid maintenance therapy has been growth retardation. Doctors believe steroids might be safely withdrawn in patients that are receiving other maintenance therapies. If steroids are removed, children might catch up in their growth and also might have fewer side effects of other kinds. This study evaluates whether steroid therapy can be withdrawn in a way that does not increase graft rejection.

Study Overview

Detailed Description

Children receiving kidney (renal) transplantation face distressing issues in post-transplantation including but not limited to growth retardation directly attributable to corticosteroids (steroids). It is hypothesized that robust immunosuppression with sirolimus and calcineurin inhibitors (cyclosporine or tacrolimus) in conjunction with induction therapy should enable successful steroid withdrawal. A steroid-free environment could lessen side effects by enabling a child to achieve catch-up growth, reducing the need for anti-hypertensive therapy, and reducing the risk of cardiovascular disease. This trial tests the objective of providing a steroid-free state without incurring the risk of increased incidence of acute transplant rejections.

Patients are enrolled prior to kidney transplantation and receive standard evaluations. Patients receive induction therapy with basiliximab preoperatively and on Day 4 after surgery. Immunosuppressive therapy begins with sirolimus and either cyclosporine or tacrolimus on Day 1 following surgery, and with corticosteroids the day of surgery. Infection prophylaxis with Bactrim is begun on Day 1 after surgery and center-specific anti-cytomegalovirus (CMV) therapy is given for all recipients of a CMV positive kidney. At 6 months post-transplantation, all patients who have not had an episode of acute rejection undergo a renal graft biopsy. Patients who are confirmed to be free of subclinical rejection are randomized to either undergo complete steroid withdrawal or continue maintenance on daily steroids. Patients receive either steroids or placebo, while continuing other immunosuppressive medications. Patients are segregated into weight groups for steroid withdrawal that occurs over months 7 to 13. Any acute rejection event during withdrawal is confirmed by renal biopsy and managed with methylprednisolone treatment. Patients are followed for 3 years post-transplantation for analysis of growth rate, blood pressure, lipid profile and renal function as measured by serum creatinine and calculated creatinine clearances. Post-transplantation clinic visits are weekly for the first 2 months, every 2 weeks until 13 months, weekly during Month 13, every 2 weeks through Month 18, and monthly until the study ends.

Patients who exhibit evidence of acute or subclinical rejection do not continue the steroid withdrawal trial and care is managed by their pediatric renal transplant center physicians.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Corticosteroid (steroid) withdrawal
All enrolled subjects who have not experienced an episode of acute rejection or other event resulting in removal from the study in the first 6 months after transplantation will undergo a protocol-driven biopsy at 6 months. Subjects with no clinical or histologic evidence of rejection will be eligible to be randomized and treated in a double-blinded (e.g., masked-neither subject nor health care providers will know treatment being received) fashion while continuing other immunosuppressive medications. Subjects in this arm will undergo complete steroid withdrawal by the end of 12 months post-transplant.
Administered as a bolus intravenous injection. The first dose is given pre-operatively, the second dose is given on post-transplant day four. Dosage is determined by individual weight.
Other Names:
  • Simulect
  • Anti-CD25 monoclonal antibody, chimeric
Participants receiving cyclosporine microemulsion formula (in lieu of tacrolimus) will have the dose adjusted to maintain a whole blood trough Abbott TDx assay monoclonal level of 175-400 ng/mL (or an equivalent high pressure liquid chromatography (HPLC) level) for the first 2 weeks after transplant. The dose will subsequently be tapered to maintain a trough level of 175-300 ng/mL from week 3 to month 3, and 50-250 ng/mL from month 3 through the end of the study at month 36 (year 3).
Other Names:
  • CsA
Participants receiving tacrolimus (in lieu of Cyclosporine) will have the dose adjusted to maintain a whole blood trough level between 10 and 15 ng/mL for the first 4weeks after transplant. Trough levels will be maintained between 5 and 10 ng/mL thereafter throughout the duration of the study.
Participants take daily (orally, either as tablets or as liquid) starting on postoperative day 1 at a dose of 6 mg/m2 and will be adjusted to maintain a trough level of 10-20 ng/mL throughout the study.
Administered at 10 mg/kg intravenously perioperatively and on postoperative day 1.
Administered orally beginning on Post-Op Day 2 and maintained for all participants until day 180. Randomization will determine whether patients will maintain this treatment following day 180.
All subjects will receive TMP SMX (Bactrim), pneumocystis jiroveci (carinii) prophylaxis, beginning on postoperative day 1 and continuing for 6 months following transplant. Dosage: 10 mg/kg taken orally three times weekly (maximum dose 160 mg).
Other Names:
  • trimethoprim/sulfamethoxazole
  • TMP SMX
Active Comparator: Control Treatment
All enrolled subjects who have not experienced an episode of acute rejection or other event resulting in removal from the study in the first 6 months after transplantation will undergo a protocol-driven biopsy at 6 months. Subjects with no clinical or histologic evidence of rejection will be eligible to be randomized and treated in a double-blinded (e.g., masked-neither subject nor health care providers will know treatment being received) fashion while continuing other immunosuppressive medications. Subjects in this arm will be maintained on low-dose (0.15 mg/kg/day) daily steroids.
