Eli Lilly and Co. said Wednesday its experimental Alzheimer’s drug appeared to slow worsening of the mind-robbing disease in a large study.

In the 18-month trial, people in the early stages of Alzheimer’s who received infusions of donanemab showed 35% less decline in thinking skills compared to those given a dummy drug, Lilly announced in a press release.

The drug is designed to target and clear away a sticky protein called beta-amyloid that builds up into brain-clogging plaques that are one hallmark of Alzheimer’s.
