Post Hoc Analysis Evaluating the Impact of Antihyperglycemic Background Therapies on Attainment of A1C Targets Without Hypoglycemia in the ACHIEVE Control Pragmatic, Real-Life Study

Background ACHIEVE Control, a prospective, open-label, randomized, pragmatic, real-life study in insulin-naive people with type 2 diabetes (A1C 8.0–11.0%), demonstrated superiority of insulin glargine 300 units/mL (Gla-300) versus first-generation standard-of-care basal insulin (SOC-BI; glargine 100 units/mL or insulin detemir) in achieving individualized A1C targets without documented symptomatic (glucose ≤3.9 mmol/L [≤70 mg/dL] or <3.0 mmol/L [<54 mg/dL]) or severe hypoglycemia (American Diabetes Association level 3) at 6 months. Noninsulin antihyperglycemic background therapies are commonly used; however, sulfonylureas may increase hypoglycemia risk. This post hoc analysis assessed outcomes according to background therapy. Methods Subgroup analyses were performed per concomitant use/nonuse of sulfonylureas, glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase 4 inhibitors, or sodium–glucose cotransporter 2 (SGLT2) inhibitors. End points (6 and 12 months) included A1C target attainment without documented symptomatic or severe hypoglycemia, A1C target attainment, and absence of documented symptomatic or severe hypoglycemia. Results Odds ratios (ORs) at 12 months mostly favored Gla-300 versus SOC-BI across subgroups except in analysis of SGLT2 inhibitors, in which ORs were similar. Among sulfonylurea users, ORs at 12 months strongly favored Gla-300 versus SOC-BI for all end points, particularly A1C target achievement without documented symptomatic hypoglycemia (glucose ≤3.9 mmol/L [≤70 mg/dL]; OR 1.25, 95% CI 1.02–1.53) or severe hypoglycemia and achievement of no documented symptomatic hypoglycemia (glucose <3.0 mmol/L [<54 mg/dL]; OR 1.25, 95% CI 1.02–1.52) or severe hypoglycemia. Conclusion The results suggest that, in insulin-naive people with type 2 diabetes, Gla-300 is effective with a risk of hypoglycemia that is lower than or similar to that of SOC-BI regardless of background medication. Individuals receiving concomitant sulfonylureas were more likely to remain without symptomatic or severe hypoglycemia with Gla-300.
