While the incidence of acute rejection and early graft loss have improved dramatically with the advent of newer immunosuppressant medications, improvements in long-term patient and allograft survival after kidney transplantation have not been achieved. The specific drug combination that provides the best outcomes with the least amount of side effects is not known. Each kidney transplant center uses the combination of drugs that they believe is optimal. This study is about identifying whether drugs that are currently approved for use in kidney transplantation can be used in a new combination safely and with potentially fewer side effects than the drug combinations that are currently used at St. Paul's Hospital and other transplant centres.

Condition Intervention
Acute Graft Rejection
Drug: Tacrolimus

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Prospective, Open Label, Pilot Study Comparing the Use of Low-target Advagraf With Rabbit Antithymocyte Globulin Induction Versus Conventional Target Advagraf With Basiliximab Induction in a Steroid-avoidance Immunosuppressive Protocol for de Novo Renal Transplant Recipients

Primary Outcome Measures:
  • New onset diabetes after transplant (NODAT) [ Time Frame: 6 months post transplant ] [ Designated as safety issue: No ]
    Composite endpoint of biopsy proven acute rejection and NODAT at 6 months post transplantation. NODAT will be defined as either FPG >7.0mmol/L OR symptoms of hyperglycemia and a random plasma glucose of >11.1 OR 2-h plasma glucose >11.1 during an oral glucose tolerance test(OGTT).

Secondary Outcome Measures:
  • Acute rejection [ Time Frame: 6 months post transplant ] [ Designated as safety issue: Yes ]
    • Patient survival
    • Graft survival
    • Frequency, severity, and treatment of hypertension
    • Frequency, severity, and treatment of hyperlipidemia (serum total cholesterol, DL, LDL, and triglycerides)
    • Weight gain
    • Infections (CMV, opportunistic infections including urinary tract infections requiring treatment, pneumonia)
    • Malignancy, including PTLD
    • Leukopenia
    • Renal function as measured by serum creatinine and MDRD eGFR
    • Therapy with anti-diabetic medications beyond 1 month post transplant

Estimated Enrollment: 30
Study Start Date: March 2012
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Low target tacrolimus (Advagraf)
This group will receive rabbit anti-thymocyte globulin (rATG) induction (3 -4 doses of 1.5 mg/kg during the first post transplant week) with IV solumedrol, MPA (Mycophenolate Mofetil or Mycophenolate Sodium), and "low-target" Advagraf.
Drug: Tacrolimus

Low target tacrolimus Advagraf (0.25mg/kg) orally once daily dosed as per manufacturer's recommendation to target trough levels as per Table 1

Table 1

Months post tx:

0-1 month, level 5-7; 1-3 months, level 4-5; and 3-6 months, level 3-4

Other Name: Advagraf
Active Comparator: Standard target tacrolimus (Advagraf)
This group will receive basiliximab induction (40 mg total) with IV solumedrol, MPA (Mycophenolate Mofetil or Mycophenolate Sodium), and "standard target" Advagraf.
Drug: Tacrolimus

Standard dose of tacrolimus Advagraf (0.25mg/kg) orally once daily dosed as per manufacturer's recommendation to target trough levels as per Table 1

Table 1

Months post tx

0-1 month; level 8-12; 1-3 months, level 6-9; and 3-6 months, level 5-8.

Other Name: Advagraf

  3. Not using diabetic medications (insulin, hypoglycemic agents) at the time of transplantation
  4. Random plasma glucose level <11.1 at the time of transplantation
  5. Peak PRA (panel reactive antibody) <10%
