Information about participating in the trial

What are the researchers trying to find out?

The purpose of the study is to evaluate the pharmacodynamics, pharmacokinetics, and safety of obicetrapib in people with early Alzheimer's disease.

How long will the treatment last?

Participants will receive obicetrapib for 24 weeks

What your involvement will entail?
  • During the study, participants will be asked to do some blood tests to analyse the plasma concentration
  • Participants will also be asked to undertake brain scans (MRI) and lumbar punctures (CSF) to see changes in biomarkers in the brain
  • To complete other tests that will assess their memory, functioning and cognition improvement (i.e. tests like MMSE, CDR-SB).

Further information on the procedures, tests and number of 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 50 and 75 years old
  • Post-menopausal or women not of child-bearing potential
  • Have a diagnosis of Alzheimer's disease according to the National Institute for Aging criteria
  • Have a score between 0.5 to 1 in the Clinical Dementia Rating-Global Score (CDR) and a score above 20 in the MMSE test questionnaire test (a test about your memory). This would suggest that the person has an impairment in their memory that is at a very mild stage
  • Have a study partner who has a sufficient contact with the participant, is willing to participate in study procedures throughout the study duration.
Who cannot participate in the study?

People cannot take part in the study if they have or have experienced:

  • Contraindication to brain scans (MRI)
  • Other degenerative dementia such as dementia with Lewy bodies, Huntington's disease, Parkinson's disease
  • A disease or conditions that may interfere with the safety, tolerability and/or study assessments, or put the participant at special risk (e.g. psychiatric symptoms, auto-immune disease, inflammatory neurological disorders, cancer).

The above list is not exhaustive. It includes the most common conditions and diseases that might exclude people from the study.
