Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Alzheimer's Disease Drug: CNP520 50mg Drug: CNP520 15mg Other: Placebo to CNP520 Phase 2 Phase 3

Detailed Description:

The study uses a randomized, double-blind, placebo-controlled, parallel group, adaptive design with variable treatment duration in approximately 2000 cognitively unimpaired participants aged 60 to 75 years, with at least one APOE4 allele (Homozygotes or Heterozygotes) and, if Heterozygotes, with evidence of elevated brain amyloid.

The screening period is expected to last about 12 weeks. Participants will receive disclosure of their individual test results for APOE genotyping and brain amyloid status.

Treatment duration is variable (event driven trial) for at least 60 months, and up to an expected maximum of 84 months.

Participants will return to the study site every three months for drug dispensing and every six months for safety and efficacy assessments, including neuropsychological scales with input from the study partner. Brain MRI scans will be conducted at month 6 and month 12, and on a yearly basis thereafter.

The Follow-up visit will be scheduled 12 weeks after the end of the Treatment Epoch. An additional CSF and / or PET AD biomarker assessments will be conducted on a voluntary basis at year 2 and 5.

The study (also known as the Generation Study 2) is conducted as part of the Alzheimer's Prevention Initiative (API) program.

Primary Outcome Measures :
  1. Time to event [ Time Frame: Through study completion, at least 5 years ]
    Event is defined as diagnosis of MCI due to AD or dementia due to AD, whichever occurs first during the course of the study, after confirmation by the adjudication committee

  2. Change in the Alzheimer's Prevention Initiative Composite Cognitive (APCC) Test Score [ Time Frame: Baseline to Month 60 ]
    Composite score derived from the specific tests from the Repeatable Battery for the Assessment of Neurological Status (RBANS), Mini-Mental State Examination (MMSE), Raven's Progressive Matrices

Secondary Outcome Measures :
  1. Change in Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) score [ Time Frame: Baseline to Month 60 ]
    To demonstrate the effects of CNP520, vs. placebo on global clinical status

  2. Change on the Total Scale score and individual neurocognitive domain index scores of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) [ Time Frame: Baseline to Month 60 ]
    To demonstrate the effects of CNP520, vs. placebo on cognition

  3. Change in the Everyday Cognition scale (ECog) total scores [ Time Frame: Baseline to Month 60 ]
    To demonstrate the effects of CNP520, vs. placebo on function reported by the participant and study partner, respectively

  4. Change in cerebral amyloid angiopathy (CAA) [ Time Frame: Through study completion, at least 5 years ]
    To demonstrate the effects of CNP520 vs placebo on CAA, as measured by Magnetic Resonance Imaging (MRI)

  5. Change on volume of brain regions [ Time Frame: Baseline to Month 60 ]
    To demonstrate the effects of CNP520 vs placebo on brain atrophy, as measured by volumetric Magnetic Resonance Imaging (MRI)

  6. Change in amyloid deposition as measured by standardized uptake ratio (SUVR) of positron emission tomography (PET) scan with amyloid radiotracer [ Time Frame: Baseline to Months 24 and 60 ]
    To demonstrate the effects of CNP520 vs placebo on Alzheimer's Disease-related biomarkers

  7. Change in CSF levels of Aβ40, Aβ42 [ Time Frame: Baseline to Months 24 and 60 ]
    To demonstrate the effects of CNP520 vs placebo on Alzheimer's Disease-related biomarkers

  8. Change in CSF levels of total tau and phosphorylated tau [ Time Frame: Baseline to Months 24 and 60 ]
    To demonstrate the effects of CNP520 vs placebo on Alzheimer's Disease-related biomarkers

  9. Number of participants with adverse events as a measure of safety [ Time Frame: Through study completion, at least 5 years ]
    To demonstrate the safety and tolerability of CNP520 vs placebo

  10. Change in neurofibrillary tangle burden as measured by standardized uptake ratio (SUVR) of PET scans with tau radiotracer (where available) [ Time Frame: Baseline to Months 24 and 60 ]
    To demonstrate the effects of CNP520 vs placebo on Alzheimer's Disease-related biomarkers

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • 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 amyloid.
  • 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).

Exclusion Criteria:

  • Any disability that may prevent the participants from completing all study requirements. -
  • 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 months.
  • Indication for, or current treatment with ChEIs and/or another AD treatment (e.g. memantine).
  • 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 monitoring.
  • 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 drug abuse.
  • Significantly abnormal laboratory results at Screening, not as a result of a temporary condition.
  • 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.
