简要总结

The objective is to assess if low pre-transplantation donor specific T-cell reactive patients measured by Enzyme-linked immunosorbent spot (ELISPOT)assay can be safely managed with Calcineurin inhibitor(CNI)-free Sirolimus(SRL)-based immunosuppression.

入选标准

  • Age of donor and recipient between 18 and 65 years.
  • End-stage renal disease and scheduled to receive a primary or secondary renal allograft from a cadaveric, a living-unrelated, or a living-related donor. Patients scheduled for a second transplant must have maintained their primary graft for at least 6 months after transplantation, with the exception of graft failure due to technical reasons.
  • Panel reactive antibody (PRA) ≤ 20%, with negative standard cross-match.
  • Women of childbearing potential must have a negative serum pregnancy test before randomization.
  • Women of childbearing potential must agree to use a medically acceptable method of contraception throughout the treatment period and for 3 months following discontinuation of assigned treatment.
  • Signed and dated informed consent prior to transplantation.

排除标准

  • Multiple organ transplants
  • Recipients of adult or pediatric en bloc kidney transplants or dual transplantation or non-heart beating donors.
  • Evidence of active systemic or localized major infection.
  • Evidence of infiltrate, cavitation, or consolidation on chest x-ray obtained during the screening/baseline evaluation.
  • Use of any investigational drug or treatment up to 4 weeks prior to transplantation.
  • Treatment with voriconazole, ketoconazole, itraconazole, fluconazole, clotrimazole, astemizole, pimozide, terfenadine, erythromycin, clarithromycin, telithromycin, troleandomycin, rifampin, rifabutin, or St. John's Wort that is not discontinued prior to randomization.
  • Treatment with aminoglycosides, amphotericin B, cisplatin, cisapride, metoclopramide, cimetidine, bromocriptine, danazol, or other drugs associated with renal dysfunction that are not discontinued prior to randomization.
  • Subjects with a screening/baseline total white blood cell count < 2,000/mm3 or absolute neutrophil count (ANC) < 500, platelet count < 100,000/mm
  • Fasting triglycerides > 400 mg/dL (> 4.6 mmol/L) or fasting total cholesterol > 300 mg/dL (> 7.8 mmol/L) despite optimal lipid-lowering therapy.
  • History of malignancy within 2 years of enrollment (except for adequately treated basal cell or squamous cell carcinoma of the skin).
  • Auto-immune diseases inactive immunosuppressive treatment ( 3 months prior to inclusion).
  • Patient with psychiatric disorders that could be non-compliance for the treatment.
  • Non Caucasian patients.
  • Active peptic ulcers that could produce intestinal absorption disorders.
  • Subjects who are known to be human immunodeficiency virus(HIV) or hepatitis B virus (HBV) positive. Patients with hepatitis C virus (HCV) positive should be excluded if polymerase chain reaction (PCR) positive or transaminates values are ≥2 upper normal value (UNV).
  • Diabetic patients.
  • Body mass index higher than 30 Kg/m2.

研究组 & 干预措施

A- negative pre-transplant ELISPOT

Experimental

Sirolimus: Start at 5 mg/day as soon as treatment allocation arrives to obtain targeting levels to 8 -15 ng/ml (immunoassay) in the first 3 months, followed by trough levels of 5-10 ng/ml.

干预措施: PRE-TRANSPLANT (PRE=before) (Drug)

B- Positive pre-transplant ELISPOT

Experimental

Tacrolimus 0.1 mg/kg/12h starting as soon as treatment allocation arrives to obtain targeting troughs levels of 8-15 ng/ml the first 3 months, followed by trough levels of 5-10 ng/ml until the end of the study.

干预措施: PRE-TRANSPLANT (PRE=before) (Drug)
