Popis: Introduction The objective of this study was to assess the effect of sitagliptin on insulin dose in patients with inadequately controlled type 2 diabetes who titrate basal insulin to a target fasting glucose level after initiating sitagliptin. Methods This was a multicenter, randomized, double-blind, placebo-controlled, 24-week clinical trial in which treatment with sitagliptin 100 mg/day or placebo was administered concurrently with insulin glargine titration, targeting a fasting glucose of 4.0–5.6 mmol/L (72–100 mg/dL). The trial randomized 660 patients with type 2 diabetes and inadequate glycemic control on insulin, with or without metformin (≥1500 mg/day) or sulfonylurea, for ≥10 weeks. Patients could remain on metformin but not sulfonylurea after randomization. Results The increase from baseline in the daily dose of insulin was less in the sitagliptin group (N = 329) compared to placebo (N = 329) (between group difference = −4.7 IU [95% confidence interval [CI] −8.3, −1.2]; p = 0.009). Patients in the sitagliptin group had lower glycated hemoglobin (HbA1c) levels after 24 weeks (between-group difference of −0.4% [95% CI −0.6, −0.3; −4.9 mmol/mol (95% CI −6.6, −3.2)]; p
