Information about the drug that will be tested in the study
Is the drug already on the market for another medical condition?
Will all participants receive the same drug?
Participants will be selected by chance to receive one of the following options:
- An oral tablet of PQ-912 once daily (evening)
- Anoral tablet of placebo (inactive substance identical in appearance to the drug being tested).
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, tolerability and efficacy of PQ912 in people with mild cognitive impairment and mild dementia due to Alzheimer's disease.
How long will the treatment last?
The duration of participation in the study is either 48, 60, 72, 84 or 96 weeks of treatment.
What will your involvement entail?
- During the study, participants will have to undergo brain scan (MRI) to see if they have amyloid pathology in their brain
- Complete some laboratory tests and neurological examinations to evaluate the emergent adverse effects (unfavourable signs, symptoms or diseases temporally associated with the use of the drug tested in the study)
- During the study, participants will be asked to complete other tests that will assess their memory, functioning, attention and psychomotor function (i.e. tests or scales like CBB-Z, NTB)
- Do physical examination and an electroencephalography (a test that records the electrical activity of the brain).
Further information on the procedures can be obtained from the study team.
