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

Abstract

AimTo 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 MethodsWe 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).ResultsOver 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.ConclusionsDapagliflozin + 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.

Dapagliflozin versus empagliflozin in patients with chronic kidney disease

“…Similarly, another study illustrated the cost-effectiveness of dapagliflozin for patients with stage 3b CKD in Japan (Kodera et al, 2022). A very recent analysis showed that the use of canagliflozin or dapagliflozin, added to the standard of care (SoC) in patients with CKD and DM, was more cost-effective than SoC only (Nguyen et al, 2023).…”

Acute Diabetes Complications After Transition to a Value-Based Medication Benefit

“… 5 Nationally, patients with diabetes pay approximately $150 to $500 per year for antidiabetic medications. 6 Most employer-sponsored plans, whether or not they have a high deductible for medical services, apply co-payments to prescriptions. 7 A less common plan type, 8 high-deductible health plans with health savings accounts, subjects almost all medications to the deductible.…”
