Wegovy Expansion: A New Era in Obesity Treatment and the Future of Weight Loss Medications
The European Medicines Agency (EMA) has approved expanded dosage options for Wegovy, a semaglutide-based medication for obesity, paving the way for more personalized treatment plans. This decision, based on a favorable opinion from the EMA’s Committee for Scientific Medicinal Products (CHMP) in December 2025, introduces new strengths of 0.25mg, 0.5mg, 1.0mg, 1.7mg, 2.4mg and 7.2mg. Currently, the oral formulation is only available in the US.
The STEP UP Studies: Demonstrating Significant Weight Loss
The approval follows two key studies, STEP UP and STEP UP T2D, lasting 72 weeks. STEP UP, involving 1,407 participants without type 2 diabetes, and STEP UP T2D, analyzing 512 participants with type 2 diabetes, demonstrated substantial weight loss in adults with obesity who received a 7.2mg dose weekly alongside lifestyle changes. Participants experienced an average weight loss of 21% of their initial body mass, significantly higher than the 2% reduction observed in the placebo group.
Notably, one in three participants achieved a weight loss of 25% or more of their initial body weight. The studies also indicated preservation of lean muscle mass, with 84% of weight loss attributed to fat reduction.
Expanding Access and Delivery Options
Novo Nordisk, the manufacturer of Wegovy, has already requested approval for a single-dose 7.2mg pen injector, anticipated to be available across the 27 EU member states later this year. Until then, healthcare professionals can prescribe the 7.2mg dosage by administering three 2.4mg semaglutide injections in a single session, maintaining the weekly injection schedule.
Wegovy 7.2mg is already approved and available in the United Kingdom. Approval is still pending with the Food and Drug Administration (FDA) in the United States.
Beyond Injections: The Rise of Oral Semaglutide
The availability of an oral semaglutide formulation in the US signals a potential shift towards more convenient administration methods. Whereas currently awaiting approval in the EU, the oral version offers an alternative for patients who prefer not to inject.
Potential Side Effects and Safety Profile
Common side effects reported during clinical trials included nausea, diarrhea, vomiting, and dysesthesia (altered sensation). Novo Nordisk emphasizes that these events were generally mild to moderate and transient.
The Broader Trend: A Growing Market for Obesity Medications
The EMA’s decision and the development of both injectable and oral formulations of semaglutide reflect a growing recognition of obesity as a chronic disease requiring medical intervention. The market for weight loss medications is expanding rapidly, driven by increasing obesity rates and a demand for effective treatment options.
Did you know? Obesity rates continue to rise globally, with significant health and economic consequences. Medications like Wegovy are becoming increasingly critical tools in addressing this public health challenge.
Future Outlook: Personalized Medicine and Combination Therapies
The future of obesity treatment is likely to involve more personalized approaches, tailoring medication dosages and delivery methods to individual patient needs. Combination therapies, combining semaglutide with other medications or lifestyle interventions, may also become more common.
ongoing research is exploring the potential of semaglutide and similar medications for treating other conditions, such as cardiovascular disease and non-alcoholic fatty liver disease.
