Oral Semaglutide in Patients With Alzheimer's Disease

What this study is testing ClinicalTrials.gov NCT07200622 ↗

Description as written by the study sponsor.

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.
