HbA1c Once-weekly subcutaneous administration of tirzepatide dose-dependently reduced HbA1c levels across all studies using the combination of GLP-1 and GIP.2, 3, 4, 5, 6 The results of the SURPASS-2 study showed that individuals who had established T2DM and were treated with tirzepatide at doses ranging from 5 to 15 mg for a duration of 40 weeks experienced a reduction in HbA1c levels ranging from 2.09% to 2.46%.3 This reduction was higher than that observed in individuals treated with semaglutide (1 mg), who experienced a 1.86% reduction in HbA1c levels.3 Similarly, in the SURPASS-3 study, individuals who received tirzepatide at doses ranging from 5 to 15 mg for 52 weeks experienced a reduction in HbA1c levels ranging from 1.93% to 2.37%, which was higher than that observed in individuals treated with insulin degludec, who experienced a decrease of 1.34%.4 In Japanese individuals with T2DM, after 52 weeks of treatment, tirzepatide at doses ranging from 5 to 15 mg reduced HbA1c levels by 2.4%3.02%.27 Additionally, in this population, tirzepatide was more effective in controlling blood glucose levels than dulaglutide administered once weekly at a dose of 0.75 mg.27 Collectively, tirzepatide elicited a much stronger HbA1c-lowering effect in all the SURPASS programs compared with placebo or active comparators, including GLP-1 RA and basal insulin.2, 3, 4, 5, 6, 27 Table 1 summarizes the main findings of the SURPASS programs and details the HbA1c lowering efficacy of tirzepatide
