CHMP recommends EU approval of Wegovy® 7.2 mg in a single-dose pen, providing up to 20.7% mean weight loss¹

Bagsværd, Denmark, 22 May 2026 – Novo Nordisk today announced that the Committee for Medicinal Products for Human Use (CHMP) under the European Medicines Agency (EMA) has adopted a positive opinion, recommending marketing authorisation of Wegovy® 7.2 mg (once-weekly injectable semaglutide 7.2 mg) in a single-dose pen for people living with obesity.

Wegovy® 7.2 mg is already available in the EU for adults with obesity, dosed as three injections of 2.4 mg, and is based on results from the STEP UP trial programme. In the STEP UP trial, semaglutide 7.2 mg injected once weekly demonstrated 20.7%¹ mean weight loss in participants with obesity, and approximately one in three people experienced 25% or greater weight loss. In the STEP UP T2D (type 2 diabetes) trial, in participants with obesity and type 2 diabetes, semaglutide 7.2 mg demonstrated a mean weight loss of 14.1%¹. In both trials, the well-known safety and tolerability profile of semaglutide was reaffirmed with semaglutide 7.2 mg, which was comparable to previous trials with semaglutide for weight management.

“Since its launch in 2021, Wegovy® has transformed the lives of many people living with obesity and even more so with the approval earlier this year of Wegovy® 7.2 mg, which delivers around 21% weight loss,” said Mike Doustdar, president and CEO of Novo Nordisk. “With Wegovy® 7.2 mg now recommended for approval in the single-dose pen, people with obesity can reach their weight and health goals through a convenient, easy-to-use pen.”

Wegovy® 7.2 mg in the single-dose pen is already approved in the US and UK. In the US, Wegovy® 7.2 mg is launched under the brand name Wegovy® HD. Novo Nordisk expects to launch Wegovy® 7.2 mg in a single-dose pen in the EU in Q3 2026.

About the STEP UP trials

The STEP UP and STEP UP T2D phase 3 trials investigated the efficacy and safety of injectable semaglutide 7.2 mg in people with obesity without or with type 2 diabetes.

The 72-week STEP UP trial evaluated the efficacy and safety of injectable semaglutide 7.2 mg compared to semaglutide 2.4 mg and placebo as an adjunct to lifestyle intervention. The trial included approximately 1,400 adults with obesity. The 72-week STEP UP T2D trial evaluated the efficacy and safety of injectable semaglutide 7.2 mg compared to placebo in approximately 500 adults with obesity and type 2 diabetes.
