- Abstract
Abstract: Aims/Introduction: Type 2 diabetes mellitus is an epidemic in Asia, yet clinical trials of glucose‐lowering therapies often enroll predominantly Western populations. We explored the initial combination of metformin and linagliptin, a dipeptidyl peptidase‐4 inhibitor, in newly diagnosed type 2 diabetes mellitus patients in Asia with marked hyperglycemia. Materials and Methods: This was a post‐hoc subgroup analysis of a multinational, parallel‐group clinical trial in which 316 newly diagnosed type 2 diabetes mellitus patients with glycated hemoglobin A1c (HbA1c) 8.5–12.0% were randomized to double‐blind oral treatment with linagliptin/metformin or linagliptin monotherapy. The primary end‐point was the change from baseline in HbA1c at week 24. We evaluated data for the 125 participants from Asian countries. Results: After 24 weeks, the mean ± standard error reduction from baseline in HbA1c (mean 10.0%) was −2.99 ± 0.18% with linagliptin/metformin and −1.84 ± 0.18% with linagliptin; a treatment difference of −1.15% (95% confidence interval −1.65 to −0.66, <italic>P</italic> < 0.0001). HbA1c <7.0% was achieved by 60% of participants receiving linagliptin/metformin. The mean bodyweight change after 24 weeks was −0.45 ± 0.41 kg and 1.33 ± 0.45 kg in the linagliptin/metformin and linagliptin groups, respectively (treatment difference −1.78 kg [95% confidence interval −2.99 to −0.57, <italic>P</italic> = 0.0043]). Drug‐related adverse events occurred in 9.7% of participants receiving linagliptin/metformin and 4.8% of those receiving linagliptin. Hypoglycemia occurred in 6.5% and 4.8% of the linagliptin/metformin and linagliptin groups, respectively, with no severe episodes. Gastrointestinal disorders occurred in 12.9% and 12.7% of the linagliptin/metformin and linagliptin groups, respectively, with no associated treatment discontinuations. Conclusions: In people from Asia with newly diagnosed type 2 diabetes mellitus and marked hyperglycemia, the initial combination of linagliptin and metformin substantially improved glycemic control without weight gain and with infrequent hypoglycemia. Initial oral combination therapy might be a viable treatment for such individuals.
