High Levels of Baseline HbA1c, FPG, and 2-Hour Postprandial Glucose Are Key Predictors for Not Achieving HbA1c < 7.0% at Six Months in People with T2DM Starting Insulin Glargine 100 U/mL

Pooled participant-level data from 16 RCTs (≥ 24 weeks) were used to explore the association of demographic and clinical markers with different levels of HbA1c achieved at Week 24 in insulin-naive people with T2DM on oral agents after starting insulin glargine 100 U/mL (Gla-100). A stepwise logistic regression analysis was performed to identify potential predictive and exploratory factors for attaining an HbA1c < 7.0%. In total, 46%, 37%, and 17% of 3,415 participants (53% male) included in the analysis achieved Week 24 HbA1c < 7.0%, 7.0-8.0%, and > 8.0%, respectively. Key clinical findings and multivariate analysis results are shown in the Table. Sex, diabetes duration, baseline BMI, HbA1c, FPG, and overall 2h-PPG were significant predictors of attaining HbA1c < 7.0% at Week 24, whereas change in FPG or 2h-PPG were not. FPG and 2h-PPG levels in the HbA1c > 8.0% group remained highest despite a higher Gla-100 dose (0.52 U/kg) and lower overall hypoglycaemia (PG < 3.9 mmol/L) rate at Week 24. In people with T2DM, high baseline HbA1c, FPG, and PPG levels are important predictors of failure of basal insulin/OAD therapy to achieve desired glycaemic goals. A more active treatment strategy targeting both fasting and postprandial hyperglycaemia appears to be indicated for people with poor glycaemic control after starting basal insulin therapy.
