Abstract
Aims: To compare the incidence of nocturnal hypoglycemia and glycemic control following bedtime or morning insulin glargine (LANTUS® ; glargine) plus glimepiride. Methods: In this 24-week, multinational, open, randomized study, 624 patients with type 2 diabetes poorly controlled on oral therapy received morning or bedtime glargine plus morning glimepiride (2, 3 or 4 mg) titrated to a target fasting blood glucose level ≤ 5.5 mmol/l. Results: The incidence of nocturnal hypoglycemia was equivalent between the two groups, with morning glargine non-inferior to bedtime (13.0 vs. 14.9 % of patients; between-treatment difference -1.9 %; one-sided 95 % confidence interval -100 %; 2.84 %). At endpoint, similar improvements in glycemic control were observed with morning compared to bedtime glargine: HbA1c : - 1.65 ± 1.21 vs. -1.57 ± 1.16 %; p = 0.42; fasting blood glucose: - 4.25 ± 2.82 vs. -4.48 ± 2.75 mmol/l; p = 0.08. The endpoint mean daily glargine dose was comparable (34.7 ± 17.4 vs. 32.4 ± 17.0 IU; p = 0.15), and there was no significant between-treatment difference in the change in body weight (2.1 vs. 1.8 kg; p = 0.39). Conclusions: Once-daily glargine can be administered in a flexible morning or bedtime regimen (plus morning glimepiride) to achieve good glycemic control without any difference in hypoglycemia.
