Estudio piloto de Selección de la Inmunosupresión basado en un régimen basado en inhibidores de CNI o libre de CNI dependiendo de la aloreactividad donante-especifica mediante el ensayo ELISPOT en receptores de un injerto renal e bajo riesgo - SIRES

Active, not recruiting

• Conditions: MedDRA version: 9.1Level: LLTClassification code 10023438Term: Kidney transplant; PATIENTS THAT RECEIVE A FIRST RENAL ALLOGRAFT TRANSPLANTATION. It has been shown that the assessment of the donor specific T-cell alloimmune response can be successfully performed by using new tools, such as the Elispot assay. The aim of this protocol is to make use of the pre-transplant donor specific cellular alloreactivity assessment by the Elispot assay, in order to evaluate if low aloresponders patients can be safely managed with a CNI-free immunosuppression regimen

3.PRA = 20%
4.Negative cytotoxic T-cell cross-match.
5.Women of childbearing potential must have a negative serum pregnancy test before randomization.
6.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.
7.Signed and dated informed consent prior to transplantation.

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1.Multiple organ transplants
2.Recipients of adult or pediatric en bloc kidney transplants or dual transplantation or non-heart beating donors.
3.Evidence of active systemic or localized major infection.
4.Evidence of infiltrate, cavitation, or consolidation on chest x-ray obtained during the screening/baseline evaluation.
5.Use of any investigational drug or treatment up to 4 weeks prior to transplantation.
6.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.
7.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.
8.Subjects with a screening/baseline total white blood cell count < 2,000/mm3 or ANC < 500, platelet count < 100,000/mm3.
9.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.
10.History of malignancy within 2 years of enrollment (except for adequately treated basal cell or squamous cell carcinoma of the skin).
11.Auto-inmune diseases in active inmunosupressive treatment ( 3 months prior to inclusion).
12.Patients with psiquiatric disorders that could be non-compliance for the treatment.
13. Active peptic ulcers that could produce intestinal absortion disorders.
14. Subjects who are known to be HIV or HBV positive ( surface antigen, HBV DNA, or e antigen positive). Patients with HCV positive should be excluded if PCR positive or transaminates values are =2UNV.
15. Diabetic patients.
16. Body mass index (BMI) higher than 30 Kg/m2. (See Attachment 5: Nomogram for Determining Body Mass Index).
