Semaglutide demonstrates superior efficacy in reducing body weight, HbA1c, and insulin requirements compared to other GLP-1RAs (liraglutide, exenatide) in patients with Type 1 Diabetes.

Among GLP-1RAs, semaglutide (1.0 mg weekly) appears to be the most effective option for Type 1 Diabetes patients, offering greater weight loss (~6 kg) and insulin reduction (~15 units/day) compared to liraglutide or exenatide. Discuss with your provider if you are a candidate for this specific agent.

GoodSupportsHIGH confidence
Subgroup analysis identified that semaglutide achieved the greatest reductions in all outcome measures... Semaglutide treatment exhibited the greatest impact, reducing insulin requirements by 14.95 U/day (95% CI: 6.31–23.58 U/day; Figure 3B).
