Cost‐effectiveness of canagliflozin and dapagliflozin for treatment of patients with chronic kidney disease and type 2 diabetes

Aim To examine the cost‐effectiveness of adding canagliflozin or dapagliflozin to standard of care (SoC) versus SoC alone in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). Materials and Methods We used a Markov microsimulation model to assess the cost‐effectiveness of canaglif...

Zusammenfassung:Aim To examine the cost‐effectiveness of adding canagliflozin or dapagliflozin to standard of care (SoC) versus SoC alone in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). Materials and Methods We used a Markov microsimulation model to assess the cost‐effectiveness of canagliflozin plus SoC (canagliflozin + SoC), dapagliflozin plus SoC (dapagliflozin + SoC) and SoC alone. Analyses were conducted from a healthcare system perspective. Costs were measured in 2021 Canadian dollars (C$), and effectiveness was measured in quality‐adjusted life‐years (QALYs). Results Over a patient's lifetime, canagliflozin + SoC and dapagliflozin + SoC yielded cost savings of C$33 460 and C$26 764 and generated 1.38 and 1.44 additional QALYs compared with SoC alone, respectively. While QALY gains with dapagliflozin + SoC were higher than those with canagliflozin + SoC, this strategy was also more costly with the incremental cost‐effectiveness ratio exceeding the willingness to pay threshold of C$50 000 per QALY. Dapagliflozin + SoC, however, generated cost savings and QALY gains compared with canagliflozin + SoC over shorter time horizons of 5 or 10 years. Conclusions Dapagliflozin + SoC was not cost‐effective versus canagliflozin + SoC in patients with CKD and T2D over the lifetime horizon. However, adding canagliflozin or dapagliflozin to SoC was less costly and more effective relative to SoC alone for treatment of CKD and T2D.
