Head-to-head comparison of Cagrilintide and Liraglutide — mechanism, side effects, legal status, and pricing.
Cagrilintide is a long-acting acylated amylin analog developed by Novo Nordisk. It is investigational and not FDA-approved; Novo Nordisk's lead development path is the CagriSema co-formulation with semaglutide for weight management. Monotherapy cagrilintide was evaluated in Phase 2 but was deprioritized in favor of the combination.
Liraglutide is an FDA-approved GLP-1 receptor agonist marketed as Victoza (type 2 diabetes, approved 2010) and Saxenda (chronic weight management, approved 2014). It was the first GLP-1 analog approved for obesity and carries an FDA boxed warning for the risk of thyroid C-cell tumors. Pediatric indications include type 2 diabetes in patients ≥10 years (Victoza) and obesity in patients ≥12 years with BMI ≥95th percentile (Saxenda).

Submit testing data →A Phase 2 dose-finding trial of cagrilintide monotherapy demonstrated dose-dependent weight loss of up to 10.8% over 26 weeks versus 3.0% for placebo (Lau et al., The Lancet, 2021). Novo Nordisk pivoted development to the CagriSema co-formulation with semaglutide 2.4 mg. The Phase 3 REDEFINE 1 trial (n=3,417, 68 weeks) in obesity reported ~22.7% mean body weight reduction on the treatment-policy estimand, with 91.9% achieving ≥5% weight loss versus 31.5% for placebo. Novo Nordisk submitted a CagriSema NDA to the FDA in December 2025; the application is under review in 2026. Cagrilintide is not FDA-approved as a standalone therapy, and CagriSema is not yet approved as of April 2026.

The SCALE Obesity and Prediabetes trial (Pi-Sunyer et al., NEJM 2015; PMID 26132939) demonstrated ~8% body-weight loss at 3.0 mg daily over 56 weeks, and the SCALE Diabetes trial (Davies et al., JAMA 2015; PMID 26284720) showed 6.0% weight loss in adults with type 2 diabetes. The LEADER cardiovascular outcomes trial (Marso et al., NEJM 2016; PMID 27295427) demonstrated a 13% relative reduction in major adverse cardiovascular events in type 2 diabetes with established CVD or high CV risk. A pediatric Phase 3 trial (Kelly et al., NEJM 2020; PMID 32233338) supported Saxenda's FDA approval for adolescents ≥12 years with obesity. While less effective than newer GLP-1 agonists for weight loss, liraglutide has the longest track record and most extensive real-world safety data. The daily dosing requirement is its main disadvantage versus weekly semaglutide.
Cagrilintide and Liraglutide are both in the Metabolic category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.
