Background and objective: In the two-replicate randomized Phase III INPULSIS® trials in patients with idiopathic pulmonary fibrosis (IPF), nintedanib 150 mg bd significantly reduced the annual rate of decline in forced vital capacity (FVC) compared with placebo. The key secondary endpoints were time to first investigatorreported acute exacerbation and change from baseline in St George's Respiratory Questionnaire total score, both over 52 weeks. Here, we assessed the effect of nintedanib in Asian patients. Methods: Pre-specified subgroup analyses of the effect of nintedanib on the primary and key secondary endpoints in Asian versus White patients were undertaken based on pooled data from the two INPULSIS ® trials. Safety data were analyzed descriptively. Results: Of the treated patients, 322 were Asian (nintedanib n = 194; placebo n = 128) and 608 were White (nintedanib n = 360; placebo n = 248). In Asian patients, the nintedanib versus placebo difference in the adjusted annual rate of decline in FVC was 94.1 mL/year (95% CI: 33.7, 154.6). The treatment effect of nintedanib on the annual rate of decline in FVC in Asian and White patients was similar (treatment-by-subgroup interaction P = 0.72) and consistent with the overall population. No significant treatment-by-subgroup interaction was observed for the key secondary endpoints between Asian and White patients. In Asian patients, the most common adverse event in the nintedanib group was diarrhoea (56.2% of patients vs 15.6% for placebo). Conclusion: In pre-specified subgroup analyses of Asian versus White patients with IPF in the INPULSIS ® trials, race did not influence the effect of nintedanib on disease progression.

Aims:To evaluate glucose-lowering treatment strategies with linagliptin and metformin in people with newly diagnosed type 2 diabetes and marked hyperglycaemia, a prevalent population for which few dedicated studies of oral antidiabetes drugs have been conducted. Methods:A total of 316 patients, with type 2 diabetes diagnosed for ≤12 months and with glycated haemoglobin (HbA1c) concentration in the range 8.5-12.0%, were randomized 1:1 to double-blind, free-combination treatment with linagliptin 5 mg once daily and metformin twice daily (uptitrated to 2000 mg/day maximum) or to linagliptin monotherapy. The primary endpoint was change in HbA1c concentration from baseline at week 24 (per-protocol completers' cohort: n = 245). Results:The mean (standard deviation) age and HbA1c at baseline were 48.8 (11.0) years and 9.8 (1.1)%, respectively. At week 24, the mean ± standard error (s.e.) HbA1c decreased from baseline by -2.8 ± 0.1% with linagliptin/metformin and -2.0 ± 0.1% with linagliptin; a treatment difference of -0.8% (95% confidence interval -1.1 to -0.5; p <0.0001). Similar results were observed in a sensitivity analysis based on intent-to-treat principles: adjusted mean ± s.e. changes in HbA1c of -2.7 ± 0.1% and -1.8 ± 0.1%, respectively; treatment difference of -0.9% (95% CI -1.3 to -0.6; p <0.0001). A treatment response of HbA1c <7.0% was achieved by 61 and 40% of patients in the linagliptin/metformin and linagliptin groups, respectively. Few patients experienced drug-related adverse events (8.8 and 5.7% of patients in the linagliptin/metformin and linagliptin groups, respectively). Hypoglycaemia occurred in 1.9 and 3.2% of patients in the linagliptin/metformin and linagliptin groups, respectively (no severe episodes). Body weight decreased significantly with the combination therapy (-1.3 kg between-group difference; p =0.0033). Conclusions:Linagliptin in initial combination with metformin in patients with newly diagnosed type 2 diabetes and marked hyperglycaemia, an understudied group, elicited significant improvements in glycaemic control with a low incidence of hypoglycaemia, weight gain or other adverse effects. These results support early combination treatment strategies and suggest that newly diagnosed patients with marked hyperglycaemia may be effectively managed with oral, non-insulin therapy.
