Abstract: Neuronal death is the final step in the progression of preclinical Alzheimer’s disease (AD) pathologies into clinically evident AD and its profound dementia. As such, a drug candidate proposed to be effective in AD must successfully prevent neuronal losses. The lack of preclinical demonstrated abilities to prevent neuronal programmed cell death may explain the recent failure of 300–400 AD drug candidates, identify a flaw in the Amyloid Hypothesis, and a risk for subsequent drug candidate interventions against AD. We propose that investigators use either animal models or small early translational clinical trials to test for AD drug candidates’ efficacy against clinically critical features of the disease, such as prevention of neuronal death. Such stringent testing would more effectively shelter AD patients from being recruited into clinical trials that are destined to fail in Phase II or III.
