Semaglutide 2.4 mg is the most cost-effective weight-management pharmacotherapy in Canada compared to standard of care (diet and exercise) and other approved drugs, primarily due to its superior ability to delay or prevent type 2 diabetes, sleep apnea, and cardiovascular events.

For adults in Canada with obesity (BMI ≥30 or ≥27 with comorbidities), Semaglutide 2.4 mg is currently the most cost-effective pharmacological treatment compared to diet/exercise alone or other drugs like Orlistat. It works by acting as a GLP-1 receptor agonist to promote weight loss and improve metabolic health. While it requires weekly injections and has a higher upfront cost, it significantly reduces the long-term risk of type 2 diabetes, cardiovascular events, and sleep apnea, making it a superior value for money in the Canadian healthcare system.

GoodSupportsHIGH confidence
From a societal perspective, at a willingness-to-pay (WTP) threshold of CAD 50 000 per QALY, semaglutide 2.4 mg was the most cost-effective treatment, at an incremental cost-utility ratio (ICUR) of CAD 31 243 and CAD 29 014 per QALY gained versus the next best alternative, i.e., orlistat, and SoC, respectively.

Why this rating

Based on a validated Markov model using data from high-quality RCTs (STEP 1, 2, 5) and network meta-analyses, though it relies on modeling of hard endpoints rather than direct long-term trial data for all outcomes.
