Summary Objective Liraglutide 3.0 mg is associated with clinically significant weight loss in clinical trials, but real‐world data are lacking. In this analysis, weight loss and persistence outcomes with liraglutide 3.0 mg were assessed across obesity classes, in a real‐world clinical setting. Methods Secondary analysis of an observational, retrospective study of liraglutide 3.0 mg for weight management (as adjunct to diet and exercise) at six Wharton Medical Clinics in Canada. Patients were categorized by body mass index (BMI, kg/m2) into obesity class I (BMI 30–34.9); class II (BMI 35–39.9); and class III (BMI ≥40). Change in weight, categorical weight loss, time to maintenance dose (defined as the time to reach the full liraglutide 3.0 mg maintenance dose) and persistence were assessed for each class and for differences between classes. Results Of 308 patients, 70 (22.7%) had obesity class I, 83 (26.9%) obesity class II and 155 (50.3%) obesity class III. Similar percentage change in weight was observed between obesity classes (mean [standard deviation, SD]: −7.0% [6.0], −6.6% [6.0] and −6.1% [5.0], respectively; p = .640), and similar proportions achieved ≥5% weight loss (60.4%, 62.0% and 55.3%, respectively; p = .717) at 6 months. Mean time to maintenance dose (SD) was 64.2 (56.4) d, 76.4 (56.3) d and 71.4 (54.5) d for obesity classes I, II and III, respectively (p = .509). Persistence with medication was also similar between obesity classes (p = .358). Conclusions These findings suggest that real‐world treatment with liraglutide 3.0 mg, regardless of obesity class, is associated with similar clinically significant weight loss, time to maintenance dose and medication persistence.

This trial assessed the efficacy and safety of the GLP-1 analogue once a week subcutaneous semaglutide 2·4 mg versus semaglutide 1·0 mg (the dose approved for diabetes treatment) and placebo for weight management in adults with overweight or obesity, and type 2 diabetes. This double-blind, double-dummy, phase 3, superiority study enrolled adults with a body-mass index of at least 27 kg/m2 and glycated haemoglobin 7–10% (53–86 mmol/mol) who had been diagnosed with type 2 diabetes at least 180 days before screening. Patients were recruited from 149 outpatient clinics in 12 countries across Europe, North America, South America, the Middle East, South Africa, and Asia. Patients were randomly allocated (1:1:1) via an interactive web-response system and stratified by background glucose-lowering medication and glycated haemoglobin, to subcutaneous injection of semaglutide 2·4 mg, or semaglutide 1·0 mg, or visually matching placebo, once a week for 68 weeks, plus a lifestyle intervention. Patients, investigators, and those assessing outcomes were masked to group assignment. Coprimary endpoints were percentage change in bodyweight and achievement of weight reduction of at least 5% at 68 weeks for semaglutide 2·4 mg versus placebo, assessed by intention to treat. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT03552757 and is closed to new participants. From June 4 to Nov 14, 2018, 1595 patients were screened, of whom 1210 were randomly assigned to semaglutide 2·4 mg (n=404), semaglutide 1·0 mg (n=403), or placebo (n=403) and included in the intention-to-treat analysis. Estimated change in mean bodyweight from baseline to week 68 was −9·6% (SE 0·4) with semaglutide 2·4 mg vs −3·4% (0·4) with placebo. Estimated treatment difference for semaglutide 2·4 mg versus placebo was −6·2 percentage points (95% CI −7·3 to −5·2; p<0·0001). At week 68, more patients on semaglutide 2·4 mg than on placebo achieved weight reductions of at least 5% (267 [68·8%] of 388 vs 107 [28·5%] of 376; odds ratio 4·88, 95% CI 3·58 to 6·64; p<0·0001). Adverse events were more frequent with semaglutide 2·4 mg (in 353 [87·6%] of 403 patients) and 1·0 mg (329 [81·8%] of 402) than with placebo (309 [76·9%] of 402). Gastrointestinal adverse events, which were mostly mild to moderate, were reported in 256 (63·5%) of 403 patients with semaglutide 2·4 mg, 231 (57·5%) of 402 with semaglutide 1·0 mg, and 138 (34·3%) of 402 with placebo. In adults with overweight or obesity, and type 2 diabetes, semaglutide 2·4 mg once a week achieved a superior and clinically meaningful decrease in bodyweight compared with placebo. Novo Nordisk.

Summary Objective Weight management medications can significantly increase patients' chances of achieving a clinically meaningful weight loss if patients persist with treatment. This retrospective observational study of de‐identified medical records of 311 patients is the first real‐world study examining persistence with liraglutide 3.0 mg in Canada, and also investigates associations between the SaxendaCare® patient support program and persistence and weight loss. Methods Overall persistence was assessed, as well as associations of enrollment in SaxendaCare®, persistence and weight loss. Results Overall mean (standard deviation) persistence with liraglutide 3.0 mg was 6.3 (4.1) months, and 67.5% (n = 210) and 53.7% (n = 167) of patients persisted for ≥4 and ≥ 6 months, respectively. Enrollment in SaxendaCare® was associated with significantly longer persistence with liraglutide 3.0 mg and greater weight loss. Patients enrolled in SaxendaCare® (n = 119) persisted for 7.9 (4.0) versus 5.2 (3.8) months for those not enrolled (n = 184) (p < 0.001), and had significantly greater percent weight loss after 6 months regardless of the duration of their persistence (−7.9% vs −5.5% from baseline, p < 0.01). Conclusions These findings suggest that, in clinical settings, persistence with liraglutide 3.0 mg can exceed 6 months, and that enrolling in SaxendaCare® may be associated with comparatively longer persistence and, regardless of persistence, greater weight loss.

Background: In people with overweight/obesity and type 2 diabetes (T2D), achievement of weight loss can be a challenge. STEP 2 investigated the efficacy and safety of semaglutide 2.4 mg for weight management in adults with overweight/obesity and T2D. Methods: This randomized, double-blind, double-dummy, placebo-controlled, phase 3 trial was conducted at 149 sites across 12 countries (NCT03552757). Adults aged ≥18 years with body mass index (BMI) ≥27 kg/m2, T2D, HbA1c between 7-10% (53-86 mmol/mol), and receiving ≤3 oral glucose-lowering agents were randomized 1:1:1 to once-weekly subcutaneous (s.c.) semaglutide 2.4 mg or 1.0 mg, or placebo, as adjunct to a reduced-calorie diet and increased physical activity for 68 weeks. The co-primary endpoints were percentage change in body weight and proportion of participants achieving weight loss ≥5% for semaglutide 2.4 mg vs placebo. Cardiovascular risk factors, glycemia and safety/tolerability were also assessed. Two estimands were defined: treatment policy and trial product; results are presented for the treatment policy estimand, unless stated otherwise. Results: 1,210 participants (mean: age 55 years, body weight 99.8 kg, BMI 35.7 kg/m2, HbA1c 8.1%, diabetes duration 8.0 years; 50.9% female) were randomized. Mean body weight change from baseline to week 68 was −9.6% with semaglutide 2.4 mg vs −3.4% with placebo (estimated treatment difference [ETD]: −6.2%; 95% confidence interval [CI]: −7.3, −5.2; p<0.0001) and −7.0% for semaglutide 1.0 mg (ETD for semaglutide 2.4 mg vs 1.0 mg: −2.7%; 95% CI: −3.7, −1.6; p<0.0001). Similar results were obtained with the trial product estimand: mean body weight change −10.6% for semaglutide 2.4 mg vs −3.1% for placebo (ETD: −7.6%; 95% CI: −8.6, −6.6; p<0.0001) and 7.6% for semaglutide 1.0 mg (ETD vs semaglutide 2.4 mg: −3.1%; 95% CI: −4.1, −2.1; p<0.0001). Participants on semaglutide 2.4 mg were more likely to achieve weight loss ≥5%, ≥10%, ≥15% and ≥20% vs placebo (68.8% vs 28.5%, 45.6% vs 8.2%, 25.8% vs 3.2% and 13.1% vs 1.6%, respectively; p value for odds ratios <0.0001 for all). Mean change in HbA1c from baseline to week 68 was −1.6% for semaglutide 2.4 mg vs −0.4% for placebo (p<0.0001). Greater improvements with semaglutide 2.4 mg vs placebo were also seen in waist circumference, BMI, systolic blood pressure, fasting plasma glucose, C-reactive protein, and lipids (HDL, VLDL, free fatty acids, and triglycerides) (p<0.05 for all). The most frequent adverse events were gastrointestinal disorders (typically transient and mild-to-moderate), occurring in 57.5%, 63.5% and 34.3% of participants receiving semaglutide 1.0 mg, 2.4 mg and placebo, respectively. Conclusion: Semaglutide 2.4 mg, as adjunct to lifestyle intervention, was efficacious and well tolerated for weight management in adults with overweight or obesity and T2D, providing significantly greater weight loss vs placebo and semaglutide 1.0 mg at week 68.
