SURPASS-2: Superior HbA1c and Weight Reduction With Tirzepatide vs. Semaglutide - Video

The SURPASS-2 trial compared three doses of tirzepatide (5 mg, 10 mg, 15 mg) with semaglutide 1 mg, in adults with type 2 diabetes who were already taking metformin. The primary aim was to assess reduction in HbA1c levels. Tirzepatide produced greater HbA1c reductions than semaglutide, with decreases of 2.1% to 2.5% depending on dose, compared to 1.9% with semaglutide. ^1,2 A significantly larger proportion of patients on the highest dose achieved tighter glycemic targets, including over 50% achieving HbA1c <5.7%, versus about 20% with semaglutide. ^1,2,3

The trial also showed greater weight loss with tirzepatide. Patients on the 15 mg dose experienced an average weight loss of 12.4 kg, compared to 6.2 kg in those taking semaglutide. This demonstrates that tirzepatide not only improves glucose control but also offers a more substantial benefit in managing obesity, which is a major concern in type 2 diabetes. ^1,2

In terms of safety, tirzepatide had a similar gastrointestinal side-effect profile to semaglutide, with nausea and other GI symptoms being the most common. Hypoglycemia rates were low across all treatment groups. ² Overall, tirzepatide provided superior glycemic control and more pronounced weight reduction compared to semaglutide, while maintaining a comparable safety and tolerability profile. ²
