The goal of this clinical trial is to evaluate whether dapagliflozin can reduce the risk of worsening kidney function or death from cardiovascular or renal causes in adults with advanced chronic kidney disease (CKD), with or without type 2 diabetes. The main questions it aims to answer are: 1. Does dapagliflozin reduce the rate of decline in kidney function or progression to end-stage kidney disease in adults with advanced CKD? 2. Does dapagliflozin reduce the risk of death from cardiovascular or renal causes in patients with advanced CKD? Researchers will compare dapagliflozin to a placebo to see if dapagliflozin improves kidney and cardiovascular outcomes in this high-risk population.
