Primary | Composite endpoint of efficacy failure [(treated biopsy-proven acute rejection, graft loss, death, or loss to follow-up) and renal function (estimated glomerular filtration rate)] of the induction regimen | Composite endpoint of efficacy failure of the induction regimen defined as occurrence of any of the following individual outcomes up to 12 months post transplantation (start of follow up at transplantation): acute rejection, graft loss or poor graft function defined as eGFR<40 ml/min. | 12 months post transplantation | |
Secondary | Prevalence of biomarker signatures at 6, 12 months of follow-up. | The following biomarker analyses are implemented in the trial:
ELISpot/CTLp EBV/CMV/BKV load + CMV/EBV T-Ly Multi-parameter flow cytometry gene expression profiling alloantibodies urinary IP-10 HO-1 polymorphisms histology (protocol/induced biopsies) |

Secondary | Health-related quality of life using SF-36v2 questionnaires at baseline (pre Transplantation), Month 1, Month 3, Month 6, and Month 12 | The SF-36v2 provides scores for each of the eight health domains and psychometrically-based physical component summary (PCS) and mental component summary (MCS) scores SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.
The eight sections are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health |
baseline (pre transplantation), Month 1, Month 3, Month 6, and Month12 | |
Secondary | Assessment of patient-specific resource consumption using a trial specific questionnaire at initial discharge, Month 3, Month 6, Month 12, and in cases of repeated hospitalization | The questionnaires capture relevant apsects of resource consumption:
In which ward(s) a patient was hospitalized Additional services (diagnostics / procedures / operations) Potential dialysis procedures (past and expected frequency in the future) Potential outpatient visits and the services consumed Employment status and potential depency on care-giving The completion requires a review of inpatient records. Part II and Part III also require a short interview with the patient about potential outpatient visits during the study period, their employment status, and potential depedency on care-giving. |
initial discharge, Month 3, Month 6, Month 12, and in cases of repeated hospitalization | |
Secondary | Health-related quality of life using EQ5D-5L questionnaires at baseline (pre Transplantation), Month 1, Month 3, Month 6, and Month 12 | EQ-5D is a standardized instrument for measuring generic health status. It has been widely used in population health surveys, clinical studies, economic evaluation and in routine outcome measurement in the delivery of operational healthcare.
The EQ-5D-5L is a Patient Reported Outcome (PRO) instrument that can generally assess the quality of life of patients, regardless of their disease, over 6 questions. It also includes a vertical EQ visual analog scale (EQ VAS, 0-100 points) and a descriptive EQ-5D-5L system, which considers the following 5 dimensions or subscales over 5 levels or possible answers. dimensions: mobility, self-sufficiency, General Activities, Pain / Physical complaints, fear / dejectedness levels: Level 1: No problems/ No pain/ Not afraid; Level 2: Slight problems/ Slight pain/ A little anxious; Level 3: Moderate problems/ Moderate pain/ Moderate anxiety; Level 4: Major problems / Severe pain/ Very anxious; Level 5: Not able to/ Extreme pain/ Extremely anxious |
