E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of the study is to demonstrate the utility and safety of the IFN-γ ELISPOT marker for the stratification of kidney transplant recipients into low and high IS regimens. The enrichment study will test non-inferiority of low IS regimen compared to high IS regimen, assuming 10% of BPAR at 6-months in the control group, and allowing a non-inferiority limit of maximum 15%. |
|
E.2.2 | Secondary objectives of the trial |
- To investigate differences across treatment arms in the following secondary outcomes: e.g. eGFR (ml/min) at 6 and 12 months etc. - Health economics, H-R QoL and treatment cost (cost/benefit) at 1, 3, 6, 12 and 24 months. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) Men and women, age ≥18 years. 2) Subject must be a recipient of a first renal transplant from a deceased or living donor. 3) Subject must have a current documented PRA <20% and no detectable anti-class I and II HLA antibodies by solid phase assay (Luminex®). 4) Subject is willing to provide signed written informed consent. 5) Women of Childbearing Potential (WOCBP) must be using a highly effective method of contraception to avoid pregnancy throughout the study in such a manner that the risk of pregnancy is minimized. WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal [defined as amenorrhea ≥ 12 consecutive months; or women on hormone replacement therapy (HRT) with documented serum follicle stimulating hormone (FSH) level > 35 mIU/mL]. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of clinical trial. |
|
E.4 | Principal exclusion criteria |
1) Subjects undergoing renal transplant with a current documented PRA >20% and/or detectable anti-class I and II HLA antibodies by solid phase assay (Luminex®). 2) CDC positive cross match. 3) Subjects receiving an allograft from a donor older than 65 years with elevated creatinine levels and/or treated diabetes. 4) Cold ischemia time (CIT) higher than 24h. 5) Subjects with a prior solid organ transplant (SOT), including renal re-transplantation, or receiving a concurrent SOT. 6) Patients previously treated with daclizumab or basiliximab. 7) Subjects with underlying renal disease of: a. Primary focal segmental glomerulosclerosis. b. Type I or II membranoproliferative glomerulonephritis c. Atypical Haemolytic uremic syndrome (HUS) / thrombotic thrombocytopenic purpura syndrome. 8) Subject with Hepatitis B chronic infection and/or active infection by Hepatitis C virus (positive PCR result) at the moment of transplant. 9) Subjects with known human immunodeficiency virus (HIV) infection. 10) Patients with active systemic infection that requires the continued use of antibiotics. 11) Patients with neoplasia except localized skin cancer receiving appropriate treatment. 12) Patients with severe anemia (hemoglobin < 6g/dl), leucopenia (WBC <2500/mm3), thrombocytopenia (platelets <80.000/mm3). 13) Hemodynamically instable patients even if their hemoglobin level counts > 6 g/dl. 14) Patients with intestinal pathology or severe diarrhoea that can hinder absorption according to medical criteria. 15) Subjects with a known hyper sensibility to any of the drugs used in this protocol. 16) Subjects who have used any investigational drug within 30 days prior to enrolment in this clinical trial. 17) WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period, women who are pregnant or breastfeeding or women with a positive pregnancy test on enrolment. 18) Subjects who are legally detained in an official institution |
