(Localized basal cell carcinoma of the skin at any time, or small (less than 4 cm) or low-grade renal cancers, bladder cancers, or treated prostate cancer with no evidence of disease after 2 years are allowable)

- Patient on renal replacement therapy.
- Patient who experienced biopsy proven rejection.
- Proteinuria > 1 g/day (as calculated from the urinary protein-to-creatinine ratio).
- Patients with recurrence of Focal Segmental Glomerulosclerosis (FSGS).

- Patients with ongoing wound healing problems, clinically significant infection requiring continued therapy or other severe surgical complication in the opinion of the investigator.
- Presence of intractable immunosuppressant complications or side effects.
- Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive serum human chorionic gonadotrophin laboratory test (>5 mIU/mL)
- Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they are using two birth control methods.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Arm 1 Everolimus/Reduced dose tacrolimus
In this arm, the myfortic® will be weaned off quickly and everolimus (Zortress®) initiated to achieve a target level of 3-8 ng/ml with a mean of 6 ng/ml.
Once achieving a therapeutic dose of everolimus (Zortress®) the tacrolimus (Prograf® or Hecoria®) dose will be reduced a target level of 3-5 ng/ml.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Renal Function
Time Frame: 2 years
|
Renal function in patients will be assessed using glomerular filtration rate (GFR) as measured by the Modified Diet Renal Disease (MDRD) estimation. Glomerular filtration is the process by which the kidneys filter the blood, removing excess wastes and fluids. Glomerular filtration rate (GFR) is a calculation that determines how well the blood is filtered by the kidneys, which is one way to measure remaining kidney function. GFR is also used to find the stage of chronic kidney disease. Glomerular filtration rate is usually calculated using a mathematical formula that compares a person's size, age, sex, and race to serum creatinine levels. The higher the GFR number, the better the kidney function; the lower the GFR number, the worse the kidney function. A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure. |
