Hypoglycemia is associated with significant morbidity in type 2 diabetes (T2D). Progression of T2D leads to declining counterregulatory responses and heightened hypoglycemia risk. In this secondary analysis of data from DEVOTE, a CVOT with 7637 patients with T2D at high risk of cardiovascular events, we investigated diabetes duration as a moderator of severe hypoglycemia (SH) with use of glargine U100 (IGlar U100) versus insulin degludec. Patients in DEVOTE were categorized by diabetes duration in years: <10, 10-15, 15-20 and ≥20. Prevalence of SH was examined by treatment arm (Table) using a negative binomial model with log-observation time as an offset term, and diabetes duration categories as moderators. Both proportion of patients with SH events and rate of SH increased with progression of disease in both arms. Degludec preserved its relative benefit over IGlar U100 for SH across diabetes duration groups, even in less progressed disease groups, i.e., an observed 52% relative risk reduction for degludec vs. IGlar U100 for patients within 10 years of disease onset (95% CI: 0.29; 0.81). There was no significant difference in treatment ratios across categories (p-value for interaction=0.50). Similar findings were confirmed in the SWITCH 2 trial (data not shown). Thus, diabetes duration did not moderate the relative reduction in rate of SH for degludec vs. IGlar U100 in DEVOTE.
