This study has 2 parts: First part is the main study and second part is the extension study. During the main study participants will receive 1 of 4 study medicines. If participants continue in the extension study, they will not receive any study medicine during the extension. The main study will look at how well CagriSema helps participants with excess body weight lose weight compared to a "dummy" medicine and 2 other medicines, cagrilintide and semaglutide. Participants will either get CagriSema, cagrilintide,semaglutide or "dummy" medicine. Which treatment participants get is decided by chance. They will take one injection once a week. The study medicine is injected briefly with a thin needle, typically in the stomach, thighs or upper arms. Extension study: After the main study, not all participants will continue in the extension study. The study staff will tell the participant if they will continue or not into the extension study. In the extension study we will look at what happens to the participant's body weight and diseases related to excess body weight after the participant stops taking the study medicine. The main study will last for about 1½ years and the extension study will last for another 2 years.
Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Novo Nordisk (NVO) is the sponsoring company for this trial. BiotechSign currently grades this company F (12/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
