Beyond amyloid?
Commenting on the negative results, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, said they demonstrate the need to focus beyond amyloid and more on the biology of aging.
“This broader approach coupled with advances in novel biomarkers is bringing us closer to the day when physicians will be able to zero in on the root causes of each patient’s Alzheimer’s – and tailor combinations of drug therapies to provide precision medicine,” Dr. Fillit, who was not involved with the research, said in statement.
Genentech is also evaluating the potential of gantenerumab for ADAD and for the prevention of sporadic AD and treatment of early Alzheimer’s in late-stage clinical trials. Results from the phase 3 GRADUATE studies of gantenerumab in early AD are expected by the end of the year.
The study was supported by the National Institute on Aging, contributions to Banner Alzheimer’s Foundation, and Genentech.
