Novo Nordisk’s Oral Semaglutide Shows Cardiovascular Benefits Comparable to Wegovy Injection

Key Takeaways:

• Novo Nordisk’s new oral semaglutide 25 mg pill improved blood glucose control and reduced cardiovascular risk factors, matching the effects of its injectable counterpart, Wegovy.
  
• Data from the OASIS 4 trial showed significant weight loss and normalisation of blood glucose in people with prediabetes.
  
• The company expects U.S. regulatory approval for the first oral GLP-1 treatment for weight management by the end of 2025.
  
  

Oral GLP-1 pill shows comparable benefits to injection

Novo Nordisk has presented new findings suggesting that its experimental oral obesity medication delivers cardiovascular and metabolic benefits similar to those achieved with its blockbuster injectable, Wegovy. The results were shared at the ObesityWeek 2025 conference in Atlanta and strengthen the Danish company’s case for approval of the pill in the United States later this year.

The oral semaglutide 25 mg tablet, part of the company’s glucagon-like peptide-1 receptor agonist (GLP-1RA) portfolio, was shown to improve blood sugar regulation and reduce cardiovascular risk factors. These results could mark a milestone in obesity care, as the pill would become the first oral GLP-1 therapy approved for weight management.

OASIS 4 trial results

The data come from the OASIS 4 clinical trial, which compared oral semaglutide 25 mg with placebo in adults with overweight or obesity. After 64 weeks, 71.1% of participants with prediabetes who received the treatment achieved normal blood glucose levels, compared with 33.3% in the placebo group.

Participants who lost at least 15% of their body weight experienced additional health benefits, including reductions in blood pressure, inflammatory markers, and triglycerides. Overall, the trial demonstrated both significant weight loss and improvements in cardiometabolic health outcomes.

The primary OASIS 4 results, published in September in the New England Journal of Medicine, reported an average weight loss of 16.6% among participants taking the oral semaglutide.

Comparable outcomes with Wegovy injection

An indirect comparison between OASIS 4 and Novo Nordisk’s earlier STEP 1 trial, which evaluated injectable semaglutide (Wegovy), found the two formulations delivered comparable outcomes in weight reduction and improvements across key cardiometabolic markers.

These findings suggest that people who prefer not to use injectables could soon have an equally effective oral alternative. As demand for obesity pharmacotherapy continues to rise, an oral formulation may further expand access and adherence to GLP-1 treatments.

Regulatory outlook and market plans

The U.S. Food and Drug Administration (FDA) accepted Novo Nordisk’s application for oral Wegovy in May and is expected to deliver a decision by the end of the fourth quarter of 2025. The company has stated that, if approved, it intends to launch the product shortly thereafter.

Despite a recent dip in share price and slower sales growth, Novo Nordisk’s prospects have been buoyed by positive trial outcomes and an improved pricing arrangement under Medicare. The company is also undergoing leadership changes, including a new Chief Executive Officer and a restructured board, amid efforts to stabilise growth.

Novo Nordisk has indicated that, once approved, the pill will be made available through telehealth platforms such as Ro and WeightWatchers, with a potential subscription model offering discounted pricing. Additionally, Hims & Hers Health recently confirmed it is in discussions with Novo to provide both injectable and oral forms of Wegovy through its digital platform.

A step forward in accessible obesity care

If approved, Novo Nordisk’s oral semaglutide could redefine accessibility and adherence in obesity care. The convenience of a pill that matches the efficacy of an injectable treatment offers a compelling new option for people managing obesity and related cardiometabolic risks.

By broadening the range of treatment modalities within the GLP-1 class, Novo Nordisk continues to shape the evolving landscape of obesity pharmacotherapy — a field that is rapidly transforming the management of metabolic health worldwide.

CCH insights

This news about oral semaglutide is very welcome, but shouldn’t come as a surprise. Oral semaglutide is the exact same compound as injectable semaglutide, and as long as the dose administered orally is sufficient to deliver a similar blood concentration as the injectable form, then the effects should be very similar. It’s the same drug, just a cheaper and easier, but less efficient, route of administration.
