Aim To assess the addition of linagliptin as an alternative to insulin uptitration in older people with type 2 diabetes on stable insulin therapy. Materials and Methods This phase 4, randomized, multicentre, double‐blinded, placebo‐controlled, 24‐week study recruited individuals on stable insulin, with baseline HbA1c 7.0%‐10.0%, aged ≥60 years and body mass index ≤45 kg/m 2 . HbA1c and fasting plasma glucose were measured at study visits, and participants assessed glycaemic control with a self‐monitoring blood glucose device. Adverse events (AEs) were reported during the study. Results Three hundred and two participants were randomized 1:1 to linagliptin 5 mg qd and placebo, with one third of patients from Japan. Study population age and HbA1c (baseline mean ± SD) were 72.4 ± 5.4 years and 8.2 ± 0.8%, respectively; ~80% of participants were aged ≥70 years; 80% had macrovascular complications, one third had a baseline estimated glomerular filtration rate <60 mL/min/1.73 m 2 ; and half had been diagnosed with diabetes for >15 years. Linagliptin significantly improved glucose control at 24 weeks (HbA1c‐adjusted mean change vs. placebo: –0.63%; P <0.0001) and the probability of achieving predefined HbA1c targets without hypoglycaemia (HbA1c <8.0%: OR 2.02; P <0.05 and HbA1c <7.0%: OR 2.44; P <0.01). Linagliptin versus placebo was well tolerated, with similar incidences of AEs, including clinically important hypoglycaemia (blood glucose <54 mg/dL) or severe hypoglycaemia. Conclusions Addition of linagliptin improves glucose control without an excess of hypoglycaemia in older patients with type 2 diabetes on stable insulin therapy.
