Abstract
Aims To investigate the impact of baseline 1,5-anhydroglucitol on the treatment effect of basal–bolus therapy in people with Type 2 diabetes. Methods Post hoc analysis of onset 3, an 18-week, randomized, phase 3 trial evaluating the efficacy and safety of fast-acting insulin aspart in basal–bolus therapy (n =116) vs. basal insulin-only therapy (n=120) in people with Type 2 diabetes. The estimated treatment difference in change from baseline in HbA 1c was investigated for different cut-off values of baseline 1,5-anhydroglucitol (2, 3, 4, 5 and 6 μg/ml). Results The estimated treatment difference in change from baseline in HbA1c between basal–bolus therapy and basal insulin‐only therapy was statistically significantly greater in participants with baseline 1,5‐anhydroglucitol ≤3 μg/ml (n = 34) vs. >3 μg/ml (n = 198) [estimated treatment difference (95% CI): −1.53% (−2.12; −0.94) vs. −0.82% (−1.07; −0.57); P‐value for interaction = 0.03]. The estimated treatment difference became more pronounced when comparing participants with 1,5‐anhydroglucitol ≤2 μg/ml (n = 15) vs. >2 μg/ml (n = 217) [estimated treatment difference (95% CI): −2.26% (−3.15; −1.36) vs. −0.85% (−1.08; −0.62); P‐value for interaction = 0.003]. For cut‐off values ≥4 μg/ml, estimated treatment differences were numerically greater below the cut‐off compared with above, although the interaction terms were not statistically significant. Conclusion This analysis indicates that people with Type 2 diabetes with low 1,5‐anhydroglucitol have an added treatment benefit with basal–bolus therapy compared with people with higher 1,5‐anhydroglucitol. Further research is needed to clarify any clinical utility of these findings. Clinical Trials Registry No: NCT01850615
