A Study of CNP520 Versus Placebo in Participants at Risk for the Onset of Clinical Symptoms of Alzheimer's Disease
The purpose of this study is to determine the effects of CNP520 on cognition, global clinical status, and underlying AD pathology, as well as the safety of CNP520, in people at risk for the onset of clinical symptoms of AD based on their age, APOE genotype and elevated amyloid.
Stanford is currently accepting patients for this trial.

Phase 2/Phase 3
- consent to receive disclosure of their risk estimates to develop clinical symptoms of
AD based on their APOE genotype and, if Heterozygotes, evidence of elevated brain
- Male or female, age 60 to 75 years inclusive. Females must be considered
post-menopausal and not of child bearing potential
- Cognitively unimpaired as evaluated by memory tests performed at screening.
- Participant's willingness to have a study partner.
- Carrier of at least one APOE4 gene if Heterozygotes, elevated brain amyloid (as
measured by CSF Abeta or amyloid PET imaging).
- Any disability that may prevent the participants from completing all study
- Current medical or neurological condition that might impact cognition or performance
on cognitive assessments.
- Advanced, severe progressive or unstable disease that may interfere with the safety,
tolerability and study assessments, or put the participant at special risk.
- History of malignancy of any organ system, treated or untreated, within the past 60
- Indication for, or current treatment with ChEIs and/or another AD treatment (e.g.
- Contraindication or intolerance to MRI.
- Brain MRI results showing findings unrelated to AD that, in the opinion of the
Investigator might be a leading cause to future cognitive decline, might pose a risk
to the participant, or might prevent a satisfactory MRI assessment for safety
- Suicidal Ideation in the past six months, or Suicidal Behavior in the past two years.
- A positive drug screen at Screening, if, in the Investigator's opinion, this is due to
- Significantly abnormal laboratory results at Screening, not as a result of a temporary
- Current clinically significant ECG findings.
- Clinically relevant depigmenting or hypopigmenting conditions (e.g. albinism,
vitiligo) or active / history of chronic urticaria in the past year.
