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.
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).
Why this rating
Based on subgroup analysis of RCTs within the meta-analysis.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
