Purpose
The purpose of this study is to learn the best way to prolong kidney life in patients exposed to calcineurin inhibitors, who already have evidence of damage possibly caused by the calcineurin inhibitor on kidney biopsy.

| Official Title: | A Randomized Controlled Trial of Reducing Calcineruin Inhibitor Target Level by 50% Versus Converting to Rapamycin in Chronic Kidney Dysfunction Without Reversible Causes |
- Kidney function will be determined by the rate of change in glomerular filtration rate (GFR), estimated by serum creatinine (eGFR). [ Time Frame: Once a week for 3 month then monthly until trial ends ] [ Designated as safety issue: Yes ]
| Enrollment: | 5 |
| Study Start Date: | January 2008 |
| Estimated Study Completion Date: | January 2014 |
| Estimated Primary Completion Date: | January 2014 (Final data collection date for primary outcome measure) |
| Arms | Assigned Interventions |
|---|---|
| Active Comparator: 50% decrease in calcineurin inhibitor |
Drug: Cyclosporins/Tacrolimus
Decrease the dose of calcineurin inhibitor by 1/2 and the drug level will be followed and adjusted to the target level of 50% of the previous levels
Other Names:
|
| Active Comparator: Rapamune |
Drug: Sirolimus
Change from current calcineurin inhibitor to Sirolumus
Other Name: Rapamune
|
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Serum creatinine increased greater than or equal to 25% over baseline with no acute or reversible cause clinically evident.
Although eGFR is arguably better for estimating kidney allograft function than serum creatinine, pragmatics dictate the use of a change in serum creatinine in the initial selection of patients. These criteria are currently used by transplant coordinators for selection of patients for the kidney biopsy as a part of large on-going study at our center.
- Adequate (greater than or equal to 8 glomeruli) biopsy showing Chronic allograft injury reported as mild/moderate CAN or CNI toxicity based on the previously used Banff 97 classification and no potentially reversible causes of graft dysfunction, e.g. acute rejection or treatable recurrent disease. Patients with histological evidence of mild recurrent disease that does not appear to be severe enough to explain the deterioration in function, e.g. IgA on immunofluorescence, or changes consistent with early diabetic nephropathy, will not be excluded.
- Receiving CsA (trough level concentration 75-125 ng/mL) or Tacrolimus(trough level concentration 6-12 ng/mL) plus MMF (or AZA) with (or without) prednisone.
- Able to give informed consent.
Exclusion Criteria:
- Urine total protein excretion >500 mg/g creatinine.
- eGFR (estimated by MDRD) <40 mL/min/1.73 m2
- Triglycerides >400 mg/dL or total cholesterol >300 mg/dL
- Allergy to macrolide antibiotic or rapamycin
- Women of child-bearing potential not using effective contraception
- Treated for acute rejection within the past 2 months
- <12 months after transplantation
- Potentially treatable cause(s) of allograft dysfunction, including acute rejection, dehydration, and congestive heart failure.
- Recurrent or de novo kidney disease that is histologically severe enough to be causing graft dysfunction
- Polyoma virus (BK) nephropathy, or serum positive for BK by polymerase chain reaction
- A second, functioning organ transplant.
- Receiving sirolimus.
- Patients with any past or present malignancy (other than non-melanoma skin cancer)
