Design outcomes

Primary

MeasureTime frame
1. The proportion of participants with deranged OGTT before and after 45 days of transplantation on immediate-release tacrolimus for CYP3A5 expressers and non-expressersTimepoint: 45 days

Secondary

MeasureTime frame
The following will be compared between the CYP3A5 expressors / non-expressors genotypes: 1.The proportion of participants with PTDM on immediate-release tacrolimus for CYP3A5 expressers and non-expressers within 12 months 2. Exposure to tacrolimus in one dosing interval (AUC 0-12) at one-month post-transplantation 3. Change in biomarkers (Fasting insulin, OGTT insulin, C-peptide in the pre-transplant period and post-transplant period (45 days). 4. Time to reach the therapeutic window, length of hospital stay, acute rejection rates, lipid profile (Triglyceride) and graft outcome (eGFR & urinary albumin)Timepoint: 3-12 months
