The drug, Crenezumab, attacks amyloid plaques in the brain.
In a clinical trial that could lead to treatments that prevent Alzheimer’s, people who are genetically guaranteed to develop the disease — but who do not yet have any symptoms — will for the first time be given a drug intended to stop it, federal officials announced Tuesday.
Experts say the study will be one of the few ever conducted to test prevention treatments for any genetically predestined disease. For Alzheimer’s, the trial is unprecedented, “the first to focus on people who are cognitively normal but at very high risk for Alzheimer’s disease,” said Dr. Francis S. Collins, director of the National Institutes of Health.
Most participants will come from the world’s largest family to experience Alzheimer’s, an extended clan of 5,000 people who live in Medellín, Colombia, and remote mountain villages outside that city. Family members with a specific genetic mutation begin showing cognitive impairment around age 45, and full dementia around age 51, debilitated in their prime working years as their memories fade and the disease quickly assaults their ability to move, eat, speak and communicate.
