Impact of baseline characteristics on the efficacy of once‐weekly subcutaneous semaglutide among participants with type 2 diabetes : A post hoc analysis of SUSTAIN China

AIMS: To investigate the impact of baseline characteristics on the efficacy of once-weekly subcutaneous semaglutide 0.5 and 1.0 mg in participants with type 2 diabetes (T2D) from the SUSTAIN China trial. METHODS: In this post hoc analysis, data for semaglutide 0.5 and 1.0 mg versus sitagliptin 100 mg were analysed in the total (n = 868) and Chinese-only (n = 605) populations. Changes from baseline to end of treatment (EOT) in glycated haemoglobin (HbA1c) and body weight were analysed by baseline age, sex, body mass index, HbA1c, diabetes duration, and homeostatic model assessment of β-cell function (HOMA-β) tertile. Proportions of participants achieving HbA1c <7.0% (53 mmol/mol) by baseline HbA1c, change from baseline to EOT in standard deviation of seven-point self-monitored plasma glucose (SMPG), derived time-in-range (dTIR) of seven-point SMPG at Week 30, and HOMA-β ratio to baseline at Week 30 were assessed for both populations. RESULTS: > 0.05). SMPG fluctuation and dTIR indicated less glucose variability in participants treated with semaglutide 0.5 and 1.0 mg versus sitagliptin, and the HOMA-β ratios to baseline at EOT were greater with semaglutide 0.5 and 1.0 mg versus sitagliptin (p < 0.05). CONCLUSIONS: These results support the effectiveness of once-weekly subcutaneous semaglutide 0.5 and 1.0 mg across a broad range of baseline characteristics, in participants with T2D from SUSTAIN China.
