Study Details
The study is being conducted to understand how the medicine, semaglutide, affects the immune system and other biological processes in people with Alzheimer's disease. Semaglutide is a medicine that doctors can prescribe in some countries for the treatment of type 2 diabetes and excess body weight. This study will help us understand whether semaglutide can also be used for the treatment of Alzheimer's disease. The study will last for about 77 weeks. In the first 12 weeks of treatment, participants will either get semaglutide (active medicine) or placebo (inactive dummy medicine). Which treatment participants get is decided by chance. In the following 52 weeks of treatment, all participants taking part in the study will get semaglutide. Participants must have a study partner, who is willing to take part in the study. Participants will get study medicine in a pen injector. The study partner will need to inject the study medicine into the skin of participant's stomach, thigh or upper arm once every week.

Arms
- Experimental: Study intervention period 1Participants will receive either semaglutide or placebo matched to semaglutide once-weekly subcutaneous (s.c.) injections for 12 weeks as an add on therapy to standard of care. Participants initially received 0.25 milligram (mg) once weekly and the dose was then escalated once in 4 weeks until the maintenance dose (1.0 mg) was reached: 0.25 mg (week 1 to week 4), 0.5 mg (week 5 to week 8), 1.0 mg (week 9 to week 12).
- Placebo Comparator: Study intervention period 2All participants will receive 1.0 mg semaglutide s.c. injections once weekly for 52 weeks during study intervention period 2 as an add-on therapy to standard of care. Participants randomised to semaglutide s.c. 1.0 mg during study intervention period 1 remained on 1.0 mg target maintenance dose for 52 weeks from weeks 12-64. Participants initially randomised to placebo during study intervention period 1 will receive semaglutide s.c. in dose escalation fashion for 8 weeks (0.25 mg from weeks 12-16 and 0.5 mg from weeks 16-20) followed by a maintenance period from weeks 20-64 at dose 1.0 mg.
