Asian Study to Investigate Safety and Efficacy of Optimized Dosing of Advagraf in Kidney Transplantation (OPTIMIZE)

A Multi-center, Randomized, Open-label, Pilot and Exploratory Study Investigating Safety and Efficacy in OPTIMIZEd Dosing of Advagraf® Kidney Transplantation in Asia.

Primary purpose of this study is to compare renal function between subjects receiving optimized dose Advagraf® over 52 weeks after kidney transplantation and subjects receiving standard dose Advagraf®. Pilot results of safety and efficacy in optimized dose Advagraf® over 52 weeks after kidney transplantation will also be obtained.

Plan for Individual participant data (IPD)

• Plan to Share Individual Participant Data (IPD)?: YES
• 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/.
• IPD Sharing Time Frame: Access to participant level data is offered to researchers after publication of the primary manuscript (if applicable) and is available as long as Astellas has legal authority to provide the data.
• IPD Sharing Access Criteria: Researchers must submit a proposal to conduct a scientifically relevant analysis of the study data. The research proposal is reviewed by an Independent Research Panel. If the proposal is approved, access to the study data is provided in a secure data sharing environment after receipt of a signed Data Sharing Agreement.
