A Research Study Comparing Active Drug in the Blood in Healthy Participants Following Dosing of the Current and a New Formulation (D) Semaglutide Tablets

In this study two different tablets for oral use of a known investigational medicinal product, called semaglutide, will be tested. One is the current formulation and the other one is a new formulation of semaglutide. Both will be administered as a tablet and are for the treatment of diabetes. Currently, semaglutide is only prescribed as injections for the treatment of diabetes in some countries. The aim of this study is to find out if the dosage strength of the current formulation of semaglutide can be reduced in the new tablet formulation. For this purpose, it will be measured how much semaglutide is taken up in the body from the two (2) different tablet formulations each with three (3) different dosage strengths. The tablet version of the study medicine is a new medicine that cannot yet be prescribed. Participants will either get semaglutide in the current tablet formulation previously tested in many large studies, or get the tablet that contains semaglutide in a new formulation - which treatment is decided by chance. Participants will get one tablet per day over 4 weeks in each of the 3 treatment periods (i.e. treatment in a total of 12 weeks). The tablets should be taken in the morning together with half a glass of water (120 mL), after an overnight fast of at least 6 hours (no food or drinks). Furthermore, water is not allowed from 2 hours before dosing. After dosing participants must wait 30 minutes before they may eat or drink. At home, participants must take their breakfast 30-45 minutes after dosing.
