Information about the drug that will be tested in the study
The drug will be administered orally once daily.
Is the drug already on the market for another medical condition?
Yes - anti-diabetic medication
Will all participants receive the same drug
Participants will be selected at random to either receive one of the following options:
- An oral dose of semaglutide (dose gradually increased from 3 to 14 mg)
- An oral dose of placebo (also called a dummy treatment which is an inactive substance identical in appearance to the drug being tested with no active therapeutic effect).
Neither the participant nor their doctor will know if the person is receiving the investigational drug or the placebo
Information about participating in the trial
What are the researchers trying to find out?
The purpose of the study is to evaluate the safety and efficiency of oral Semaglutide in people with early Alzheimer´s disease.
How long will the treatment last?
Around 3 years
What your involvement will entail?
- During the study, participants will be asked to complete a test that will assess memory, orientation, judgment and problem solving, personal care and community affairs (this is a test called CDR-SB)
- During the study, participants will be asked to complete tests that will assess their functioning, behaviour and quality of life (i.e. tests like ADCS-ADLMCI)
- Participants will be asked to undertake brain scans (MRI or CT) plus either a PET scan or a lumbar puncture (CSF) to see changes in biomarkers in the brain
- Participants will also need to complete some other questionnaires to evaluate their cognition, behaviour and function (e.g. NPI, MMSE).
Further information on the procedures, tests and visits can be obtained from the study team.
Who can participate in this study?
Who can participate in the study?
To take part in the study, participants must:
- Be between 55 and 85 years old
- Have a diagnosis of mild cognitive impairment or mild dementia of the Alzheimer’s type according to the National Institute on Aging/Alzheimer's Association core clinical criteria
- Have a score of 0.5 to 1 in the Clinical Dementia Rating-Global Score (CDR) and a score of 22 or above in the MMSE test (a test about your memory). This would suggest that the person has an impairment in their memory that is at a mild stage
- Have evidence of abnormal accumulation of amyloid in their brain (PET scan or CSF)
- If the person is taking approved symptomatic medication for dementia (i.e. donepezil, rivastigmine, galantamine or memantine) the dosing regimen must have been stable for at least three months
- Have a study partner who has a sufficient contact with the participant and is willing to participate in study procedures throughout the study duration.
Who cannot participate in the study?
Exclusion criteria include:
- Participant who have relevant neurological disorder other than mild cognitive impairment or mild dementia both of the Alzheimer's type (i.e. Parkinson's disease, Lewy body disease, frontotemporal dementia of any type, Huntington's disease)
- Brain scans showing significant abnormality
- A pregnancy or lactation for female participants.
The above list is not exhaustive. It includes the most common conditions and diseases that might exclude people from the study.
