More Information


This study involves repeated doses of LY3303560 given by IV infusion every month for 80 weeks. LY3303560 is a substance called an antibody. It targets Tau, which is a protein in the brain that builds up during the progression of Alzheimer's disease. This study will examine how safe repeated doses of LY3303560 are (when compared to a placebo), its impact on the cognitive progression of participants with early symptomatic Alzheimer's Disease, and how LY3303560 is handled by the body and acts in the body.

You will first be screened to make sure you are eligible to participate in the study.  The screening period can last up to 8 weeks and includes a PET scan and MRI scan as well.  After screening, you will be randomly assigned to 1 of 3 treatment groups: either study drug (1400mg, 5600mg), or placebo (liquid in a syringe that has a similar appearance to the study drug, but has no medicine). The study drug will be given through an intravenous (IV) line, every 4 weeks for 76 weeks.
