Vildagliptin-insulin combination improves glycemic control in Asians with type 2 diabetes
Abstract
AIM: To assess the efficacy and safety of vildagliptin 50 mg bid as add-on therapy to insulin in Asian patients with type 2 diabetes mellitus (T2DM).
METHODS: This was a post hoc analysis of a subgroup of Asian patients from a multicenter, randomized, double-blind, placebo-controlled, parallel-group study in T2DM patients inadequately controlled by stable insulin therapy, with or without metformin. A total of 173 patients were randomized 1:1 to receive treatment with vildagliptin 50 mg bid (n = 87) or placebo (n = 86) for 24 wk. Changes in HbA1c and fasting plasma glucose (FPG), from baseline to study endpoint, were analyzed using an analysis of covariance model. Change from baseline to endpoint in body weight was summarized by treatment. Safety and tolerability of vildagliptin was also evaluated.
RESULTS: After 24 wk, the difference in adjusted mean change in HbA1c between vildagliptin and placebo was 0.82% (8.96 mmol/mol; P < 0.001) in Asian subgroup, 0.85% (9.29 mmol/mol; P < 0.001) in patients also receiving metformin, and 0.73% (7.98 mmol/mol; P < 0.001) in patients without metformin, all in favor of vildagliptin. There was no significant difference in the change in FPG between treatments. Weight was stable in both treatment groups (+0.3 kg and -0.2 kg, for vildagliptin and placebo, respectively). Overall, vildagliptin was safe and well tolerated with similarly low incidences of hypoglycemia (8.0% vs 8.1%) and no severe hypoglycemic events were experienced in either…
How strong is the evidence?
Evidence Hub reads this as a randomized trial. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 173 participants or records.
