Efficacy and safety in tirzepatide-treated Korean adults with type 2 diabetes-A post hoc analysis of SURPASS-AP-combo and SURPASS-3

초록

Aims: This post hoc analysis assessed the efficacy and safety data in tirzepatidetreated Korean patients with type 2 diabetes (T2D). Materials and Methods: Data specifically from Korean patients treated with tirzepatide 5, 10, or 15 mg in the multicentre, randomised, open-label, parallel-group, phase 3 trials SURPASS-AP-Combo and SURPASS-3 were extracted and analysed. Efficacy (change from baseline in glycated haemoglobin [HbA1c] and body weight, and proportions of participants achieving HbA1c and body weight targets) and safety endpoints were evaluated at week 40 (SURPASS-AP Combo) and week 52 (SURPASS-3). Results: In the SURPASS-AP-Combo and SURPASS-3, 79 of 687 and 27 of 1079 tirzepatide recipients, respectively, were Korean. In Korean participants in SURPASS-AP-Combo across all tirzepatide doses, least squares mean (LSM) HbA1c was reduced from baseline by 2.75% to 3.25% and HbA1c targets of <7.0% and <= 6.5% were achieved by 84.6% to 100% at week 40; LSM body weight reductions of-6.8% to -10.9% from baseline were achieved. The composite endpoint of HbA1c <= 6.5% without body weight gain or clinically significant documented symptomatic or severe hypoglycaemia was achieved by 69.2% to 85.2% of tirzepatide recipients. Findings were similar in Korean participants of SURPASS-3. The safety profile of tirzepatide in Korean participants was generally consistent with that in the overall SURPASS-AP-Combo and SURPASS-3 populations. Conclusions: Consistent with the overall results of the SURPASS-AP-Combo and SURPASS-3 trials, this post hoc subgroup analysis found clinically meaningful reductions in HbA1c and body weight after treatment periods of 40 to 52 weeks in Koreans with T2D treated with tirzepatide.
