Revamping Weight Loss Solutions Using Anti-Obesity Medication

Recently FDA-approved drug semaglutide has proven as a highly effective anti-obesity medication showcasing remarkable weight loss benefits.

FDA has recently approved semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, as an effective anti-obesity medication, demonstrating substantial weight loss results in both long-term clinical trials and short-term real-world studies.

The study was presented at this year’s European Congress on Obesity (ECO2023, Dublin, 17-20 May) and led by Dr. Andres Acosta and Dr. Wissam Ghusn, Precision Medicine for Obesity Program at the Mayo Clinic, Rochester, MN, USA, and colleagues.

‘Semaglutide, an FDA-approved glucagon-like peptide-1 (GLP-1) receptor agonist, has emerged as a powerful anti-obesity medication, delivering significant weight loss outcomes in extensive long-term clinical trials and real-world studies. ’

Empowering the Journey of Weight Loss Medication

However, little is known about the weight loss and metabolic parameters outcomes in mid-term real-world studies. In this study, the authors assessed weight loss outcomes associated with semaglutide in patients with overweight and obesity with and without type 2 diabetes (T2DM) at 1-year follow-up.

They performed a retrospective, multicentre (Mayo Clinic Hospitals: Minnesota, Arizona, and Florida) data collection on the use of semaglutide for the treatment of obesity.

They included patients with a body mass index (BMI) ≥27 kg/m2 (overweight and all higher BMI categories) who were prescribed weekly semaglutide subcutaneous injections (doses 0.25, 0.5, 1, 1.7, 2, 2.4mg; however most were on the higher dose 2.4mg). They excluded patients taking other medications for obesity, those with a history of obesity surgery, those with cancer, and those who were pregnant.

Conquering Obesity as a Powerful Tool

The primary endpoint was total body weight loss percentage (TBWL%) at 1 year. Secondary endpoints included the proportion of patients achieving ≥5%, ≥10%, ≥15%, and ≥20% TBWL%, change in metabolic and cardiovascular parameters (blood pressure, HbA1c [glycated hemoglobin, a measure of blood sugar control], fasting glucose and blood fats), TBWL% of patients with and without T2DM, and frequency of side effects during the first year of therapy.

A total of 305 patients were included in the analysis (73% female, mean age 49 years, 92% white, mean BMI 41, 26% with T2DM). Baseline characteristics and weight management visit details are presented in Table 1 full abstract.

In the entire cohort, the mean TBWL% was 13.4% at 1 year (for the 110 patients who had weight data at 1 year). Patients with T2DM had a lower TBWL% of 10.1% for 45 of 110 patients with data at 1 year, compared to those without T2DM of 16.7% for 65 of 110 patients with data at 1 year.

The percentage of patients that lost more than 5% of their body weight was 82%, more than 10% was 65%, more than 15% was 41%, and more than 20% was 21% at 1 year.

Uncovering Weight Loss Success in Clinical Trials

Semaglutide treatment also significantly decreased systolic and diastolic blood pressure by 6.8/2.5 mmHg; total cholesterol by 10.2 mg/dL; LDL of 5.1 mg/dL; and triglycerides of 17.6 mg/dL. Half of the patients experienced side effects related to medication use (154/305) with the most reported being nausea (38%) and diarrhea (9%) (Figure 1D).

The side effects were mostly mild not affecting the quality of life but in 16 cases they resulted in stopping the medication.

The authors conclude: “Semaglutide was associated with significant weight loss and metabolic parameters improvement at 1 year in a multi-site real-world study, demonstrating its effectiveness in the treatment of obesity, in patients with and without T2DM.”

The Mayo team is preparing several other manuscripts relating to semaglutide, including weight outcomes in patients who had weight recurrence after bariatric surgery; weight loss outcomes in patients who were on other anti-obesity medications previously compared to those who were not.
