BRIGHT demonstrated similar HbA1c reduction and hypoglycemia risk with the second-generation basal insulin analogs insulin glargine 300 U/mL (Gla-300) and insulin degludec 100 U/mL (IDeg) over 24 weeks, and less anytime (24 h) hypoglycemia with Gla-300 during the first 12 weeks, in T2DM. This analysis examined HbA1c change and confirmed (≤70 mg/dL and &lt;54 mg/dL) hypoglycemia by baseline characteristics.
BRIGHT was a multicenter, open-label, randomized, active-controlled, parallel-group trial in T2DM. Participants receiving multiple oral agents ± GLP-1 RAs were randomized to Gla-300 (N=466) or IDeg (N=463), titrated to a fasting SMPG of 80-100 mg/dL.
Efficacy and safety with Gla-300 vs. IDeg were unaffected by age (≥65 years), gender, BMI category (&lt;30/30-35/≥35 kg/m2) or diabetes duration (≥10 years). However, significant heterogeneity of treatment effect across subgroups (p=0.015) suggested greater HbA1c reduction with Gla-300 than IDeg with impaired renal function (eGFR &lt;60 mL/min/1.73 m2) (Table), with no difference in hypoglycemia incidence or rates. Further analyses revealed lower confirmed (≤70 mg/dL) hypoglycemia rates with Gla-300 vs. IDeg in those with normal renal function, with comparable HbA1c reduction (Table).
In conclusion, Gla-300 appears to confer advantages vs. IDeg in those with impaired renal function, warranting further investigation.
