A weekly injection of Wegovy leads to an average weight loss of around 15%, alongside changes to diet and exercise.
That has effectively delayed the launch in most of Europe, following the recent launch of Wegovy in Denmark and Norway.
Novo Nordisk has also had to overcome problems at a contract manufacturer.
Novo Nordisk also said the number of people with obesity is forecast to rise to 1.5 billion by 2035.
Research and development chief Martin Lange said that the company plans to investigate how to maintain the weight loss after stopping the drug.
