ListOutcomeTime frameDescription
PrimaryEvaluation of Graft Survival in Subjects Who Have Undergone Kidney Transplantation After Imlifidase Administration.5 years after first dose of imlifidase (in the feeder study)The primary endpoint of this study is to determine overall graft survival, defined as time from transplantation to graft loss.
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Patient Survival.5 years after first dose of imlifidase (in the feeder study)Overall patient survival defined as time from transplantation to death for any cause
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Kidney Function (Estimated Glomerular Filtration Rate (eGFR)).5 years after first dose of imlifidase (in the feeder study)Kidney function as evaluated by estimated glomerular filtration rate (eGFR). eGFR was calculated according to the Modification of Diet in Renal Disease (MDRD) equation.
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Kidney Function (Plasma (P)-Creatinine).5 years after first dose of imlifidase (in the feeder study)Kidney function as evaluated by analysis of plasma (P)-creatinine
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Kidney Function (Proteinuria).5 years after first dose of imlifidase (in the feeder study)Kidney function as evaluated by proteinuria by dipstick analysis
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Number of Graft Rejection Episodes.5 years after first dose of imlifidase (in the feeder study)
Recording of occurrence of graft rejection episodes classified by Banff criteria (Haas et al 2018). The following criteria had to be fulfilled by the rejection episode to constitute an antibody-mediated rejection (AMR): * a biopsy was taken at the time of the graft rejection episode * histological evidence of an AMR was reported in the pathology report * presence of detectable levels of donor specific antibodies (DSAs) and/or evidence of antibody-mediated morphological changes in the kidney transplant at the time of the biopsy
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Treatment of Graft Rejection Episodes.5 years after first dose of imlifidase (in the feeder study)Recording of graft rejection episodes treatments (e.g. dialysis, plasmapheresis and medications).
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Comorbidities.5 years after first dose of imlifidase (in the feeder study)Recording of comorbidities up until year 5 after treatment with imlifidase
SecondaryEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Treatments of Comorbidities.5 years after first dose of imlifidase (in the feeder study). Note: concomitant immunosuppressive medication up until year 5Recording of concomitant immunosuppressive medication
SecondaryAssessment of Safety Laboratory Testing in Terms of Hematology (Hb)5 years after first dose of imlifidase (in the feeder study)Blood samples were analyzed for hemoglobulin (Hb)

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYEvaluation of Graft Survival in Subjects Who Have Undergone Kidney Transplantation After Imlifidase Administration.5 years after first dose of imlifidase (in the feeder study)
The primary endpoint, overall graft survival, was analyzed by the Kaplan-Meier survival method and presented with 95% confidence limits. The following events were censored at the time of occurrence: withdrawal from the trial without graft loss, death not caused by graft loss, and end of trial without graft loss.

SECONDARYEvaluation of Long-term Clinical Outcomes of Transplanted Subjects Treated With Imlifidase in Terms of Patient Survival.5 years after first dose of imlifidase (in the feeder study)
The overall patient survival was analyzed by the Kaplan-Meier survival method and presented with 95% confidence limits. The following events were censored: withdrawal from the trial while alive, and end of trial while alive
