Japanese drugmaker Eisai presented the results of its Phase 3 clinical trial (CLARITY AD) at the Clinical Trials on Alzheimer’s Disease (CTAD) conference last month. The trial evaluated the safety and effectiveness of Lecanemab, an experimental drug for Alzheimer’s disease. Results indicated that the drug helped slow cognitive decline in patients in the early stages of the disease.
Lecanemab is a monoclonal antibody designed to target amyloid plaques in the brain which are an indicator of Alzheimer’s disease. The same drug is being studied locally within MADRC as part of the AHEAD study at Brigham & Women’s Hospital.
“The AHEAD study is testing Lecanemab in a much earlier stage of AD than the Clarity AD trial,” said Dr. Reisa Sperling, professor of neurology at Harvard Medical School, and co-principal investigator of the AHEAD Study. “The ability to identify people at risk for developing cognitive decline due to AD based on amyloid PET provides the opportunity to test whether early intervention can delay cognitive decline.”
The AHEAD study is the first ever clinical trial to test the effect of Lecanemab in people who have no cognitive symptoms of Alzheimer’s disease (AD), but in whom biomarker tests indicate amyloid is present in the brain, known as “preclinical” AD. The AHEAD study is also the first AD trial to recruit people as young as 55 years old who are at risk of developing symptoms of AD as they get older.
The AHEAD study will test whether the clinical effects reported in the Clarity AD clinically symptomatic population are similar in the AHEAD preclinical AD population. For more information about AHEAD, visit
