What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Acute Rejection (AR)
Time Frame: From first dose to month 12
AR is an immune response against the donor graft that causes tissue impairment and potential failure. The criteria for rejection was performed by the local histopathologist following the "Histological Grading of Liver Biopsies for Rejection", the "Banff diagnostic categories for renal allograft biopsies".
From first dose to month 12
Percentage of Participants with Biopsy-Proven Acute Rejections (BPAR)
Time Frame: From first dose to month 12
AR is an immune response against the donor graft that causes tissue impairment and potential failure. The criteria for rejection was performed by the local histopathologist following the "Histological Grading of Liver Biopsies for Rejection", the "Banff diagnostic categories for renal allograft biopsies". A BPAR episode was defined as any AR episode confirmed by biopsy.
From first dose to month 12
Percentage of Participants with clinically suspected Rejection
Time Frame: From first dose to month 12
AR is an immune response against the donor graft that causes tissue impairment and potential failure. The criteria for rejection was performed by the local histopathologist following the "Histological Grading of Liver Biopsies for Rejection", the "Banff diagnostic categories for renal allograft biopsies". An AR was clinically suspected in participants who experienced an increase in serum creatinine, after the exclusion of other causes of graft dysfunction (generally with biopsy).
From first dose to month 12
Number of Participants who Died
Time Frame: From first dose to month 12
Number of participants who died is recorded during 12 months' post-transplant; any cause of death was taken into account.
From first dose to month 12
Number of participants with graft failure
Time Frame: From first dose to month 12
Graft failure is defined as graft dysfunction including re-transplantation, graft loss or death, during the study period. A graft dysfunction to permanent dialysis in kidney transplantation was also considered as graft failure.
From first dose to month 12
Number of dose adjustments throughout the study period
Time Frame: From first dose to month 12
The number of dose changes will The dose adjustments required for the organ transplant were reported. The Safety Analysis Set (SAF) consisted of all participants who took at least one dose of study drug.
From first dose to month 12
Number of participants with Treatment Emergent adverse events (AEs)
Time Frame: From first dose to month 12
An AE is defined as any untoward medical occurrence in a participant administered a study drug not necessarily linked to this treatment. An AE can be any unfavorable and unintended sign (e.g., abnormal laboratory finding; abnormal laboratory test result or other safety assessment, symptom, or disease temporally associated with the use of a study drug, whether or not considered related to the study drug. Treatment emergent adverse event (TEAE) is defined as AE observed after administering the study drug.
From first dose to month 12
Whole Blood Trough Levels of Tacrolimus
Time Frame: From month 1 through month 12 (predose)
Tacrolimus whole blood trough levels are routinely monitored from whole blood samples, using a local assay method, for example EMITÒ or Liquid-Chromatography-Mass-Spectrometry-Mass-Spectrometry (LC-MS-MS) in the local laboratories.
From month 1 through month 12 (predose)

IPD Plan Description

Access to anonymized individual participant level data collected during the study, in addition to study-related supporting documentation, is planned for studies conducted with approved product indications and formulations, as well as products terminated during development. Studies conducted with product indications or formulations that remain active in development are assessed after study completion to determine if Individual Participant Data can be shared. Further details on Astellas' data sharing policy can be found at https://www.clinicaltrials.astellas.com/transparency/.
