Experimental Treatment Shows Promise in Delaying Alzheimer's Symptoms for Genetically At-Risk Individuals
March 20, 2025
Recent research suggests that an experimental treatment may delay Alzheimer's symptoms in individuals with genetic predispositions, particularly those in their 40s and 50s.
The study involved 22 participants who have been receiving amyloid-removing drugs for an average of eight years, highlighting the need for ongoing funding to confirm the long-term benefits of this treatment.
Gantenerumab, the drug under investigation, targets beta amyloid, a protein associated with plaque formation in the brains of Alzheimer's patients.
Researchers are actively seeking additional funding to expand the study and further validate these promising findings.
Experts stress the necessity for more extensive research to either confirm or refute the results of this study, ensuring continued support for the participants involved.
Initial trials indicated that gantenerumab reduced amyloid levels, but cognitive benefits were not observed in a symptom-free group, prompting an open-label extension study.
One participant, Jake Heinrichs, has remained symptom-free for over a decade despite a genetic predisposition to Alzheimer's, raising concerns about potential funding cuts that could affect ongoing treatment.
The participants were initially part of the Knight Family DIAN-TU-001 trial launched in 2012, which aimed to evaluate anti-amyloid drugs for Alzheimer's prevention.
Currently, participants are transitioning to Leqembi, an FDA-approved intravenous treatment, to further assess its effectiveness in preventing Alzheimer's symptoms over the next five years.
Maria C. Carrillo, Chief Science Officer at the Alzheimer’s Association, emphasized the significance of these findings and the critical need for continued research into Alzheimer's prevention.
Dr. Randall Bateman, the study's lead researcher, expressed optimism about the potential for delaying Alzheimer's symptoms and extending cognitive health for those at risk.
The ongoing research aims to investigate the duration of dementia delay through amyloid removal, with hopes of developing preventive treatments against Alzheimer's disease.
