---|---|
Experimental: Study intervention period 1
Participants 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).
|
Drug: Semaglutide
Semagllutide will be administered once weekly subcutaneously. Drug: Placebo Placebo matched to semaglutide will be administered once weekly subcutaneously. |
Placebo Comparator: Study intervention period 2
All 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.

Drug: Semaglutide
Semagllutide will be administered once weekly subcutaneously. |
- Change in gene expression assessed by single-cell ribonucleic acid sequencing (scRNAseq) (cells in cerebrospinal fluid [CSF]) [ Time Frame: From baseline (week 0) to visit 5 (week 12) ]Measured as number of differentially expressed genes.
- Change in gene expression assessed by scRNAseq (cells in blood) [ Time Frame: From baseline (week 0) to visit 5 (week 12) ]Measured as number of differentially expressed genes.
- Number of treatment emergent adverse events (TEAEs) [ Time Frame: From baseline (week 0) to visit 5 (week 12) ]Measured as count of events. An adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a product, whether or not considered related to the product. A TEAE is defined as an event for which the onset of the event occurs during the treatment period.
- Number of treatment emergent adverse events (TEAEs) [ Time Frame: From baseline (week 0) to end of treatment (week 64) ]Measured as count of events. An adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a product, whether or not considered related to the product. A TEAE is defined as an event for which the onset of the event occurs during the treatment period.
- Weekly average semaglutide concentration (Cavg) based on population pharmacokinetic (PK) analysis [ Time Frame: From visit 3 (week 4) to end of treatment (week 64) ]Measured in nanomoles per liter (nmol/L).
