Abstract

Type 2 diabetes (T2D) and chronic kidney disease (CKD) are major public health challenges. People with T2D and CKD have high risks of cardiovascular (CV) events and kidney failure. Novel drug classes, including sodium-glucose cotransporter-2 inhibitors (SGLT-2i), glucagon-like peptide-1 receptor agonists (GLP-1RA), and nonsteroidal mineralocorticoid receptor antagonists (nsMRA), have provided more cardiorenal protection for treatment of T2D and CKD than standard of care (SoC). This thesis examines the comparative efficacy in improving CV and renal outcomes and assesses the cost-effectiveness of these novel drugs for treatment of T2D and CKD. This thesis has four chapters. Chapter 1 provides background information about epidemiology, disease burden, definition, and treatment of T2D and CKD. It also describes the study design and reviews the existing literature. Chapter 2 is a systematic review and network meta-analysis comparing the relative efficacy of SGLT-2i, GLP-1RA, and nsMRA in improving CV and renal outcomes in patients with T2D and CKD. We found that SGLT-2i provided better cardiorenal protection than GLP-1RA and nsMRA in patients with T2D and CKD. There were no significant differences between GLP-1RA and nsMRA in reducing CV and renal outcomes. Chapter 3 examines the cost-effectiveness of adding SGLT-2i (canagliflozin or dapagliflozin) to SoC versus SoC alone for the treatment of T2D and CKD. Our study showed that adding canagliflozin or dapagliflozin to SoC was cheaper and more effective than SoC alone. Dapagliflozin plus SoC incurred lower cost and was more effective than canagliflozin plus SoC over the 5- or 10-year horizons, but it was not cost-effective versus canagliflozin plus SoC over longer time horizon. Chapter 4 concludes and discusses implications, limitations, and future research directions in T2D and CKD treatment.
