Marked weight loss on liraglutide 3.0 mg: Real-life experience of a Swiss cohort with obesity

Effectiveness and safety of drugs for obesity

Recent publicity around the use of new antiobesity medications (AOMs) has focused the attention of patients and healthcare providers on the role of pharmacotherapy in the treatment of obesity. Newer drug treatments have shown greater efficacy and safety compared with older drug treatments, yet access to these drug treatments is limited by providers' discomfort in prescribing, bias, and stigma around obesity, as well as by the lack of insurance coverage. Now more than ever, healthcare providers must be able to discuss the risks and benefits of the full range of antiobesity medications available to patients, and to incorporate both guideline based advice and emerging real world clinical evidence into daily clinical practice. The tremendous variability in response to antiobesity medications means that clinicians need to use a flexible approach that takes advantage of specific features of the antiobesity medication selected to provide the best option for individual patients. Future research is needed on how best to use available drug treatments in real world practice settings, the potential role of combination therapies, and the cost effectiveness of antiobesity medications. Several new drug treatments are being evaluated in ongoing clinical trials, suggesting that the future for pharmacotherapy of obesity is bright.

Weight loss and treatment patterns in a real-world population of adults receiving liraglutide 3.0 mg for weight management in routine clinical practice in Switzerland (ADDRESS study)

AIM

To assess weight loss associated with liraglutide 3.0 mg treatment in individuals with obesity (body mass index [BMI] ≥30 kg/m2 ) or overweight (BMI > 27 to <30 kg/m2 ) in a reimbursed, real-world setting in Switzerland.

MATERIALS AND METHODS

ADDRESS was a non-comparative, multicentre, retrospective exposure cohort study in Switzerland, examining weight loss in individuals with obesity or overweight whose treatment was reimbursed (divided into BMI subgroups) or non-reimbursed. The primary outcomes were proportions of participants in the reimbursed cohort achieving predefined weight loss targets with liraglutide 3.0 mg at Week 16 (≥5% and ≥7% for the lower BMI [28 to <35 kg/m2 with weight-related comorbidities] and higher BMI [≥35 kg/m2 ] subgroups, respectively) and Month 10 (additional ≥5% from Week 16; per Swiss reimbursement criteria).

RESULTS

The full analysis set comprised 258 individuals (195 reimbursed; 63 non-reimbursed). In the reimbursed cohort, 139 individuals (71.3%) achieved their weight loss targets at Week 16. Of individuals who met the Week-16 criteria, 43.2% attained an additional 5% weight loss at Month 10. In 162 individuals for whom data were recorded at Month 10, the mean (standard deviation) relative weight loss from baseline to Month 10 was -12.4% (6.4%).

CONCLUSIONS

Although reimbursement criteria may be difficult to achieve, particularly the additional weight loss of 5% from Week 16 to Month 10, a clinically relevant overall weight loss from baseline to Month 10 was shown in most individuals with obesity or overweight who received liraglutide 3.0 mg.

Evaluation of the Effectiveness of Liraglutide on Metabolic Parameters in the Treatment of Obesity

Background One of the essential chronic diseases is obesity, which negatively affects the individual and society. Liraglutide (LG) is an effective treatment for both obesity treatment and metabolic control. This study aims to show the effect of a 3.0 mg dose of LG, injected subcutaneously once a day, on weight loss and metabolic parameters. Methods This retrospective single-center study included 67 patients (60 women and seven men) with a BMI of at least 27 kg/m2 with comorbidities or a BMI of at least 30 kg/m2. Demographic characteristics, anthropometric measurements, and biochemical data of the participants were evaluated at the end of the four and 16 weeks. Results The mean body weight (BW) loss of patients using LG at 16 weeks was -11.71±2.21 kg. After the four and 16 weeks of beginning the LG use, the patients who lost more than 5% of initial BW were 38.8% vs. 76.1%, respectively (p=0.034). The mean baseline Homeostatic Model Assessment-Insulin Resistance Index, hemoglobin A1c, low-density lipoprotein, and triglycerides values were significantly higher than the 4 and 16 weeks (p<0.001). Twenty-two (32.8 %) patients experienced side effects (SE) after starting LG treatment, and the most common SE was found to be nausea (29.4%). Conclusion The use of LG, which is not covered by insurance, together with diet and exercise, has been shown to have clinically significant weight loss and a positive effect on glycemic values ​​and lipid profile.

Impact of Treatment with GLP1 Receptor Agonists, Liraglutide 3.0 mg and Semaglutide 1.0 mg, While on a Waiting List for Bariatric Surgery

BACKGROUND

Weight loss before undergoing metabolic and bariatric surgery (MBS) has been suggested to reduce perioperative complications, although with controversial results. The objective of this study is to evaluate the impact of treatment with GLP1-R agonists (liraglutide 3.0 mg and semaglutide 1.0 mg) on preoperative weight loss and patients' decisions regarding MBS while on a surgical waiting list.

MATERIALS AND METHODS

One hundred and two patients on a waiting list for MBS started treatment with GLP1-RA for at least 6 months. Changes in weight at 26 and 52 weeks, the number of patients achieving >5% weight loss, and patients' decisions regarding MBS were evaluated.

RESULTS

After 52 weeks, patients lost 16.9 ± 7.2% of weight with semaglutide 1.0 mg and 16.1 ± 5.8% of weight with liraglutide 3.0 mg. All patients lost ≥5% of initial weight, 84.7% lost ≥10%, 54.6% lost ≥15%, and 27.5% reached ≥20%. A total of 68.6% of participants were satisfied with the achieved weight loss and withdrew from the waiting list for MBS. A threshold of >15.1% weight loss had the greatest sensitivity and specificity for the final decision regarding undergoing MBS.

CONCLUSIONS

Losing >15% of initial weight after 52 weeks of treatment with liraglutide 3.0 mg or semaglutide 1.0 mg during the waiting list for MBS impacts patients' decisions regarding the final acceptance or rejection of the procedure.

Novel Anti-obesity Therapies and their Different Effects and Safety Profiles: A Critical Overview

Obesity has become an epidemic and a worldwide problem and its treatment is ever-evolving. Apart from diet and exercise, medication and surgery are other options. After disappointing side effects of various obesity drugs, new treatments showed promising results. This review discusses the following anti-obesity drugs: liraglutide, semaglutide, tirzepatide, orlistat, as well as the phentermine/topiramate and bupropion/naltrexone combinations. These drugs have been approved by the Food and Drug Administration (FDA) for weight reduction except for tirzepatide which is still under evaluation. Efficacy and tolerable safety profiles of some of these drugs contribute to the management of obesity and reduce the complications associated with this chronic disease.
