Aim: To assess the efficacy and safety of insulin degludec/liraglutide (IDegLira) versus insulin degludec (degludec) in Chinese people with type 2 diabetes (T2D) treated with basal insulin. Materials and Methods: In DUAL II China, a randomized, double‐blinded, multicentre, treat‐to‐target trial, Chinese adults with T2D and HbA1c of 7.5% or more on basal insulin and metformin, with or without other oral antidiabetic drugs (OADs), were randomized 2:1 to 26 weeks of treatment with either IDegLira (max. dose 50 U degludec/1.8 mg liraglutide) or degludec (max. 50 U/day), respectively, combined with metformin. At 26 weeks, superiority of IDegLira over degludec was assessed for change in HbA1c (primary endpoint), and body weight and number of severe or blood glucose (BG)‐confirmed hypoglycaemic episodes (confirmatory secondary endpoints). Results: Overall, 453 participants were randomized to IDegLira (n = 302) or degludec (n = 151). Superiority was confirmed for IDegLira over degludec in HbA1c change (−1.9% vs. −1.0%, respectively, estimated treatment difference [ETD] [95% confidence interval]: −0.92% [−1.09; −0.75], P <.0001), body weight change (−0.7 vs. +0.4 kg, respectively, ETD [95% CI]: −1.08 kg [−1.63; −0.52], P =.0002) and severe or BG‐confirmed hypoglycaemia (estimated rate ratio [95% CI]: 0.53 [0.30; 0.94], P =.0297). The odds of achieving HbA1c less than 7.0% without hypoglycaemia and/or weight gain were greater with IDegLira than degludec (P <.0001 for all). Daily insulin dose at 26 weeks was lower for IDegLira (34.3 U) than degludec (37.4 U) (P =.0014). No unexpected safety signals were observed. Conclusions: IDegLira may be an efficacious and well‐tolerated treatment intensification option for Chinese people with T2D uncontrolled on basal insulin and OADs. [ABSTRACT FROM AUTHOR]

Aims/Introduction: This secondary analysis of the 24‐week SMART study examined the efficacy of add‐on saxagliptin or acarbose to metformin across different patient subgroups with type 2 diabetes mellitus, based on baseline characteristics. Materials and Methods: Randomized patients (n = 481) were classified into subgroups based on their baseline age (<65, ≥65 years), body mass index (BMI; <24, 24–<28, ≥28 kg/m2), glycated hemoglobin (HbA1c; <8%, 8–<9%, 9–<10%, ≥10%) and renal function (creatinine clearance 50–<80, ≥80 mL/min). Treatment effects on primary outcome (HbA1c) and key secondary outcomes of fasting plasma glucose (FPG), 2‐h postprandial glucose and homeostatic model assessment of β‐cell function were assessed across patient subgroups. Results: For saxagliptin, reductions in HbA1c from baseline to week 24 were consistent across different subgroups regardless of baseline age, body mass index, HbA1c and renal function (range −0.66 to −1.16%). Saxagliptin was associated with consistent reductions in FPG (−0.60 to −1.33 mmol/L) and 2‐h postprandial glucose (−0.48 to −1.95 mmol/L) across the majority of subgroups studied. The efficacy of acarbose on FPG attenuated progressively with increasing baseline HbA1c (+0.86 to −1.43 mmol/L); an increase from baseline FPG was observed in patients with HbA1c >9%. The effect of acarbose on postprandial glucose was also variable (+0.23 to −3.38 mmol/L). Conclusions: As add‐on to metformin, both saxagliptin and acarbose reduced HbA1c regardless of baseline HbA1c, age, body mass index and renal function; however, only saxagliptin was effective at a stable glycemic control (FPG and PPG). The efficacy of acarbose on FPG and PPG was significantly attenuated in patients with higher baseline HbA1c (≥8%). [ABSTRACT FROM AUTHOR]
