Randomized Controlled Trial
Linagliptin (BI 1356), a potent and selective DPP-4 inhibitor, is safe and efficacious in combination with metformin in patients with inadequately controlled Type 2 diabetes.
The efficacy and safety of the dipeptidyl peptidase-4 inhibitor, linagliptin, added to ongoing metformin therapy, were assessed in patients with Type 2 diabetes who had inadequate glycaemic control (HbA(1c) ≥ 7.5 to ≤ 10%; ≥ 58.5 to ≤ 85.8 mmol/mol) with metformin alone. ⋯ The addition of linagliptin to ongoing metformin treatment in patients with Type 2 diabetes was well tolerated and resulted in significant and clinically relevant improvements in glycaemic control, with 5 mg linagliptin being the most effective dose.
