Efficacy of vildagliptin in combination with insulin in patients with type 2 diabetes and severe renal impairment.

Background: The purpose of this study was to evaluate the efficacy of vildagliptin 50 mg once daily in patients with severe renal impairment (estimated glomerular filtration rate < 30 mL/min/1.73 m(2)) and longstanding type 2 diabetes not adequately controlled with insulin therapy, which is a difficult-to-treat population, with limited therapeutic options and a high susceptibility to hypoglycemia.

Methods: This was a post hoc subanalysis of data obtained during a previously described randomized, double-blind, parallel-group, 24-week study comparing the efficacy and safety of vildagliptin 50 mg once daily versus placebo in patients with type 2 diabetes and moderate or severe renal impairment.

Efficacy and safety of nateglinide in type 2 diabetic patients with modest fasting hyperglycemia.

Nateglinide is a fast-acting insulin secretion agent that specifically targets postprandial hyperglycemia in patients with type 2 diabetes. The recent reduction in the diagnostic criteria for diabetes and improved understanding of the importance of early insulin secretion served as the rationale for this multicenter, double-blind, randomized, parallel-group, 24-wk study performed in 675 patients with type 2 diabetes but only moderately elevated fasting plasma glucose (FPG) (FPG = 7.0-8.

Inhibition of dipeptidyl peptidase IV improves metabolic control over a 4-week study period in type 2 diabetes.

Objective: Glucagon-like peptide-1 (GLP-1) has been proposed as a new treatment modality for type 2 diabetes. To circumvent the drawback of the short half-life of GLP-1, inhibitors of the GLP-1-degrading enzyme dipeptidyl peptidase IV (DPP IV) have been examined. Such inhibitors improve glucose tolerance in insulin-resistant rats and mice.
