Study summary

Long-term allograft function in kidney transplant recipients (KTRs) remain suboptimal, and graft failure causes significant morbidity and mortality, with cardiovascular disease being the leading cause of death in KTRs and the most common cause of death with a functioning graft. Sodium-glucose cotransporter 2 (SGLT2) inhibitors safely lower cardiovascular and kidney disease risk in the non-transplant population, yet data in KTRs are lacking. This clinical trial seeks to establish the efficacy and safety of dapagliflozin, a SGLT2 inhibitor, for improving cardiovascular and kidney graft function in adult KTRs with type 2 diabetes and post-transplant diabetes, and to leverage innovate translational methods to define the underlying mechanisms of action.
