Lower Hypoglycemia Rates with Insulin Glargine 300 U/mL (Gla-300) vs. Insulin Degludec 100 U/mL (IDeg-100) in Insulin-Naïve Adults with T2DM on Oral Antihyperglycemic Therapy ± GLP-1RA—The BRIGHT Randomized Study

This 24-week open-label, treat-to-target trial (NCT02738151) investigated the efficacy and safety of Gla-300 vs. IDeg-100 in insulin-naive T2DM, inadequately controlled on oral antihyperglycemic drugs ± GLP-1 RAs. Non-inferiority of Gla-300 vs. IDeg-100 was demonstrated for the primary endpoint (HbA 1c change, baseline to week 24). Here we analyzed hypoglycemia by treatment period; day 1 to week 24 (full study period), day 1 to week 12 (titration period) and week 13 to week 24 (maintenance period). Incidence of confirmed [≤70 mg/dL] or severe hypoglycemia at any time of day (24 h) was lower with Gla-300 vs. IDeg-100 (odds ratio 0.74 [95% confidence interval: 0.57 to 0.97]) during the titration period but was similar at any time of day (24 h) or at night (00:00-05:59 h) during the maintenance and full study periods. Annualized rates of hypoglycemia (Figure) were lower with Gla-300 vs. IDeg-100 during the full study period, particularly over the titration period, despite higher final daily doses of Gla-300 vs. IDeg-100 (0.54 and 0.43 U/kg from starting doses 0.2 U/kg and 10 U/day [0.12 U/kg], respectively). Gla-300 resulted in similar incidence but lower rates of hypoglycemia, particularly during the titration period, with comparable glycemic control vs. IDeg-100 in insulin-naive people with T2DM ± GLP-1 RA.
