PLAINSBORO, N.J., Nov. 5, 2021 /PRNewswire/ -- Results from the STEP 5 phase 3b trial, presented today at the ObesityWeek^®2021 interactive congress, showed that adults treated with Wegovy™ (semaglutide) injection 2.4 mg achieved significant and sustained weight loss over the two-year study period.¹ The STEP 5 trial investigated Wegovy™ vs. placebo, both used with a reduced calorie meal plan and increased physical activity, for the treatment of obesity (BMI ≥30 kg/m²) or overweight (BMI ≥27 kg/m²) in 304 adults for 104 weeks (two years).¹

In the STEP 5 trial, results showed that Wegovy™ significantly reduced body weight from baseline to week 104 compared to placebo (-15.2% vs. -2.6%, estimated treatment difference: -12.6% points [95% CI: -15.3, -9.8]; p<0.0001). The study also demonstrated that adults with overweight or obesity were more likely to lose at least 5% of their body weight with Wegovy™ vs. placebo (77.1% vs. 34.4%; p<0.0001).¹

"People with obesity try on average seven times to lose weight before seeking medical care. Once weight is lost, however, it all too often comes back, which is why it is critically important to find options to help people living with obesity lose weight and keep it off," said W. Timothy Garvey, MD, Professor of Medicine, Department of Nutrition Sciences at the University of Alabama in Birmingham. "Results from the STEP 5 clinical trial demonstrated that adults with obesity were able to lose weight while taking Wegovy™ and maintain the weight loss at two years, which can help us better treat and manage obesity as a chronic disease."

Based on 68-week trials, the most frequently reported adverse events with Wegovy™ were nausea, diarrhea, vomiting, constipation, and abdominal pain.² In the STEP 5 trial, the safety profile of Wegovy™ was in line with previous STEP phase 3a trials; 5.9% of patients treated with Wegovy™ and 4.6% of patients treated with placebo permanently discontinued treatment as a result of adverse events.¹

"Obesity is a chronic disease associated with at least 60 other health conditions and decreased life expectancy. With Wegovy™, we have a significant opportunity to drive meaningful change in how obesity is treated," said Doug Langa, Executive Vice President, North America Operations and President of Novo Nordisk Inc. "We are making strides by bringing an important option forward that can help people with obesity. The interest from patients and healthcare professionals is truly humbling and underscores how great this unmet need really is, as well as our responsibility to the obesity community."

Important Safety Information

What is the most important information I should know about Wegovy™?
Wegovy™ may cause serious side effects, including:

Possible thyroid tumors, including cancer. Tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer. In studies with rodents, Wegovy™ and medicines that work like Wegovy™ caused thyroid tumors, including thyroid cancer. It is not known if Wegovy™ will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.
Do not use Wegovy™ if you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Do not use Wegovy™ if:

you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
you have had a serious allergic reaction to semaglutide or any of the ingredients in Wegovy™.

Before using Wegovy™, tell your healthcare provider if you have any other medical conditions, including if you:

About the STEP clinical trial program and STEP 5
STEP (Semaglutide Treatment Effect in People with obesity) is a phase 3 clinical development program with Wegovy™ in obesity. The global phase 3a program consisted of four trials and enrolled approximately 4,500 adults with overweight or obesity.⁴

STEP 5 is a 104-week phase 3b randomized, double-blind, placebo-controlled, multi-center clinical trial comparing Wegovy™ with placebo in 304 adults with overweight (BMI ≥27 kg/m²) with at least one weight-related comorbidity or obesity (BMI ≥30 kg/m²), without diabetes, as an adjunct to lifestyle intervention.¹

The co-primary endpoints of the trial were a change in body weight (%) and proportion of participants who achieved greater than or equal to 5% weight loss at week 104. Confirmatory secondary endpoints evaluated the number of participants achieving a body weight reduction ≥10% and ≥15% from baseline at 104 weeks and change from baseline to week 104 in waist circumference and systolic blood pressure.¹

About obesity
Obesity is a chronic, progressive and misunderstood disease that requires long-term medical management.⁵^,6,7One key misunderstanding is that this is a disease of willpower, when in fact there is underlying biology that prevents people from losing weight and keeping it off. ⁸ Obesity is influenced by a variety of factors, including genetics, appetite signals, behavior and the environment.⁸ It is a gateway disease and is associated with at least 60 other health conditions.⁹ The current COVID-19 pandemic has highlighted that obesity also increases the risk for severe illness and hospitalization due to COVID-19. ¹⁰^,11,12,13

The global increase in the prevalence of obesity is a public health issue that has severe cost implications to healthcare systems.^14,15 In the United States, more than 42% of adults live with obesity.¹⁶
