The weight loss market has witnessed a significant shift with the introduction of Wegovy, a medication that has been making waves in the healthcare industry. As a semaglutide injection, Wegovy has proven to be a game-changer for individuals struggling with obesity and weight-related issues. But when exactly was Wegovy approved for weight loss, and what led to its development? In this article, we’ll delve into the timeline of Wegovy’s approval, its clinical trials, and the science behind its effectiveness.
The Road to Approval: A Brief History of Wegovy
Wegovy, developed by Novo Nordisk, is a glucagon-like peptide-1 (GLP-1) receptor agonist. The first GLP-1 receptor agonist, exenatide, was approved by the FDA in 2005 for the treatment of type 2 diabetes. Since then, several other GLP-1 receptor agonists have been developed, including liraglutide, which was approved in 2010 for diabetes treatment and later expanded to include weight management in 2014.
The development of Wegovy began in the early 2010s, with Novo Nordisk initiating clinical trials to assess its safety and efficacy in treating obesity. The company’s research focused on creating a medication that could not only help with weight loss but also improve cardiometabolic health outcomes.
Clinical Trials: The STEPS Program
The STEPS (Semaglutide Treatment Effect in People with Sustained Diabetes and Obesity) program was a comprehensive clinical trial program designed to evaluate the safety and efficacy of Wegovy in treating obesity. The program consisted of four phase 3 clinical trials:
- STEPS 1: A 68-week trial evaluating the efficacy and safety of Wegovy 2.4 mg versus placebo in 1,961 adults with obesity or overweight.
- STEPS 2: A 68-week trial assessing the efficacy and safety of Wegovy 2.4 mg versus placebo in 1,024 adults with type 2 diabetes and obesity or overweight.
- STEPS 3: A 68-week trial evaluating the efficacy and safety of Wegovy 2.4 mg versus placebo in 614 adults with obesity or overweight and moderate to severe renal impairment.
- STEPS 4: A 20-week trial assessing the efficacy and safety of Wegovy 2.4 mg versus placebo in 303 adults with obesity or overweight and frequent migraine.
The STEPS program demonstrated significant weight loss and improvements in cardiometabolic risk factors, including reductions in body weight, body mass index (BMI), and waist circumference. Additionally, the trials showed improvements in blood sugar control, lipid profiles, and blood pressure.
Key Findings from the STEPS Program
The STEPS program results showcased the following key findings:
- Significant weight loss: Wegovy 2.4 mg resulted in a mean weight loss of 14.9% to 17.6% compared to 2.4% to 3.1% with placebo.

What is Wegovy, and how does it aid in weight loss?
Wegovy is an injectable medication used for chronic weight management in adults with obesity or overweight, especially those with weight-related health conditions. It contains a higher dose of semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, which helps regulate appetite and glucose metabolism. Wegovy works by mimicking a natural hormone in the body that helps to reduce hunger and increase feelings of fullness.
In clinical trials, Wegovy has been shown to be effective in helping people lose weight and maintain weight loss over time. It has also been found to reduce the risk of weight-related health problems, such as heart disease and stroke. Wegovy is administered via injection once a week and is intended to be used in conjunction with a healthy diet and regular exercise.
When was Wegovy approved by the FDA for weight loss?
Wegovy was approved by the United States Food and Drug Administration (FDA) on June 4, 2021, for chronic weight management in adults with obesity or overweight, particularly those with weight-related health conditions.
