OBJECTIVE

In participants with type 2 diabetes (T2D) and HbA1c >9.0–10.0%, guidelines recommend treatment with basal-bolus insulin.

RESEARCH DESIGN AND METHODS

This randomized trial compared the efficacy and safety of insulin degludec and liraglutide (IDegLira) and basal-bolus among participants with high HbA1c ≥9.0–15.0%, previously treated with 2 or 3 oral agents and/or basal insulin, allocated (1:1) to basal-bolus (n = 73) or IDegLira (n = 72). The primary end point was noninferiority (0.4%) in HbA1c reduction between groups.

RESULTS

Among 145 participants (HbA1c 10.8% ± 1.3), there was no statistically significant difference in HbA1c reduction (3.18% ± 2.29 vs. 3.00% ± 1.79, P = 0.65; estimated treatment difference (ETD) 0.18%, 95% CI −0.59, 0.94) between the IDegLira and basal-bolus groups. IDegLira resulted in significantly lower rates of hypoglycemia <70 mg/dL (26% vs. 48%, P = 0.008; odds ratio 0.39, 95% CI 0.19, 0.78), and less weight gain (1.24 ± 8.33 vs. 5.84 ± 6.18 kg, P = 0.001; ETD −4.60, 95% CI −7.33, −1.87).

CONCLUSIONS

In participants with T2D and HbA1c ≥9.0–15.0%, IDegLira resulted in similar HbA1c reduction, less hypoglycemia, and less weight gain compared with the basal-bolus regimen.
