30-OR: Empagliflozin Delays Need for Insulin Initiation in Patients with Type 2 Diabetes and Cardiovascular Disease: Findings from EMPA-REG OUTCOME

Insulin in T2D is associated with hypoglycemia and weight gain, requires training, can be expensive, and is generally not preferred by patients. Reducing insulin needs is attractive to both patients and practitioners. In EMPA-REG OUTCOME, 7020 patients were treated with empagliflozin (EMPA) 10, 25 mg, or placebo (PBO). Median follow-up was 3.1 yrs. After the first 12 weeks, changes in background glucose-lowering therapy were permitted. We assessed treatment effects of pooled EMPA vs. PBO on time to new initiation of insulin among insulin-naïve patients and time to total daily insulin dose increase by >20% among insulin-treated patients. In 3633 (52%) insulin-naïve patients, EMPA reduced need for insulin use vs. PBO by 54% (11.1% vs. 22.3%; HR 0.46 [0.39-0.54]), adjusted for key covariates (Figure). In 3387 (48%) patients using insulin at baseline, EMPA reduced need for a >20% increase in insulin dose by 57% (19.1% vs. 36.8%; HR 0.43 [0.37-0.49]). Reductions in incident insulin use was most pronounced in patients within 5 yrs of T2D diagnosis (HR 0.31 [0.21-0.45]) compared with T2D duration of >5-10 yrs (0.42 [0.31-0.59]) or >10 yrs (0.56 [0.44-0.71); P<sub>interaction =0.03. In patients with T2D and CVD, EMPA markedly and durably delays the need for insulin initiation, more so in those recently diagnosed, and reduces need for large dose increases in those already using insulin.
