Eli Lilly and Company

Information about the drug that will be tested in the study


The drug will be administered via an intravenous infusion (an injection into the vein).

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 intravenous infusion of Donanemab
  • An intravenous infusion 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 Donanemab in people with early symptomatic Alzheimer's disease.

How long will the treatment last? 

Around 1.5 year.

What will your involvement entail?
  • During the study, participants will have to undergo brain scan (MRI, PET) to see if they have amyloid pathology in their brain
  • Complete a memory test (MMSE) to assess cognitive function
  • Complete a test that will assess memory, orientation, judgment and problem solving, personal care and community affairs (this is a test called CDR)
  • Participants will also need to complete some other tests to evaluate their cognition, behaviour, function and quality of life, activities of daily living (e.g. ADAS-Cog, ADCS-iADL).

Further information on the procedures can be obtained from the study team.

  • Be 60 to 85 years old
  • Have a gradual and progressive change in memory function for the past 6 months

  • 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?

Exclusion criteria include:

  • Contraindication to PET imaging and MRI procedures
