简要总结

Alzheimer's disease (AD) is a progressive neurodegenerative disease and a major global healthcare burden. Currently, the disease is only treated symptomatically and an effective disease-modifying therapy (DMT) that may slow the disease progression, and prevent cognitive and functional deterioration, is yet to emerge. Glucagon-like peptide-1 (GLP-1) analogues are being studied to treat neurodegenerative diseases, due to evidence of their neuroprotective effects in mouse models of AD. This study investigates Semaglutide, a modified human GLP-1RA in Alzheimer's disease to understand the mechanism of the disease. The primary objective of this study is to evaluate the safety and tolerability of oral semaglutide in individuals with mild AD. Moreover, the secondary objective of the study is to evaluate the change in synaptic density using PET before and after treatment with semaglutide.

  • An individual who can act as a reliable study partner with regular contact
  • Diagnosis of Alzheimer's disease according to the revised NIA-AA criteria
  • Age from 50 years
  • Mini-Mental State Examination (MMSE) score of ≥18; likely complete all the assessments
  • Rosen Modified Hachinski Ischemic score ≤4
  • On stable medication for 2 months before the screening visit; on or off cholinesterase inhibitors

  • Likely to be able to participate in all scheduled evaluations and complete all required tests

排除标准

  • Any contraindications to the use of oral semaglutide
  • Significant neurological disease other than AD that may affect cognition
  • MRI/CT showing unambiguous aetiological evidence of cerebrovascular disease with regard to their dementia or vascular dementia fulfilling NINCDSAIREN criteria

  • Myocardial infarction within the last 1 year
  • Other clinically significant abnormality on physical, neurological or laboratory examination that could compromise the study or be detrimental to the subject
  • History of alcohol or drug dependence within the last 2 years
  • Current use of narcotic medications which could affect cognition. Subjects on anticoagulants will be allowed, but will not have an arterial line inserted
  • Women of childbearing potential. Women who could become pregnant will be required to use adequate contraception throughout the trial. Please see appendix A for more information. All women of childbearing potential will take a pregnancy test before the PET scan.

结局指标

主要结局

To evaluate the safety and tolerability of oral semaglutide in an AD population.

时间窗: Adverse events monitoring: Baseline; Weeks 4, 8, 26, 39, 52

To assess the safety and tolerability of (1-year) Semaglutide treatment in patients with AD using composite outcome measure of the adverse events evaluated from the safety assessments. This will be assessed by the number of participants using a composite measure generated from abnormal vital signs, abnormal 12-lead ECG readings, abnormal laboratory (blood) tests, abnormalities found in MRI scans, abnormal physical exam findings, and abnormal neurological/psychiatric evaluation.

次要结局

  • To evaluate the change in synaptic density using [18F] SynVesT-1 before and after treatment.([18F] SynVesT-1 PET will be conducted at baseline and Week 52 (end of treatment).)
