Brief Summary:
The purpose of this study is to test whether two investigational drugs called CAD106 and CNP520, administered separately, can slow down the onset and progression of clinical symptoms associated with Alzheimer's disease (AD) in participants at the risk to develop clinical symptoms based on their age and genotype.

Condition or disease Intervention/treatment Phase
Alzheimer's Disease Biological: CAD106 Immunotherapy Other: Placebo to CAD106 Drug: CNP520 Other: Placebo to CNP520 Phase 2 Phase 3

Detailed Description:

This study will assess the effects of each of the two therapies given separately, both targeting amyloid, on cognition, global clinical status, and underlying pathology in participants at risk for the onset of clinical symptoms of Alzheimer's disease (AD). Cognitively unimpaired individuals with two APOE4 genes and age 60 to 75 years, inclusive, are selected as they represent a population at particularly high risk of progression to Mild Cognitive Impairment and/or dementia due to Alzheimer's disease.

The study follows a randomized, double-blind, placebo-controlled, two-cohort, parallel group design in which participants receive one of the investigational treatments or their matching placebo for at least 60 months up to a maximum of 96 months and no longer than when the target number of events for the TTE endpoint has been observed and confirmed in either cohort.

An unbalanced randomization (active: placebo) of 5:3 ratio in Cohort I (430 CAD106 :260 Placebo) and 3:2 ratio in Cohort II (390 CNP520 : 260 Placebo) will be applied. Randomization will be stratified by age group (60-64 years, 65-75 years) and region (North America/Other , Europe).

Participants who meet study entry requirements will be required to undergo at least two PET scans during the course of the study. Additional PET scans, blood and CSF collection will be voluntary. The study (also known as the Generation Study 1) is conducted as part of the Alzheimer's Prevention Initiative (API) program.

Primary Outcome Measures :
  1. Time to diagnosis of MCI due to Alzheimer's Disease (AD) or dementia due to Alzheimer's Disease [ Time Frame: Through study completion, an average of 5 years ]
    Time when diagnosis is confirmed by 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 assess the effects of CAD106 and CNP520, vs. respective placebo on global clinical status as measured by the change in Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) score.

  2. Number of participants with Adverse Events as a measure of Safety and Tolerability [ Time Frame: Through study completion, an average of 5 years ]

    To assess the safety and tolerability of CAD106 and CNP520, vs. respective placebo by measured adverse events (AEs), and changes in the brain structural MRI, laboratory tests, non-cognitive neurological and psychiatric examinations including the Columbia Suicide Severity Rating Scale (C-SSRS), vital signs and electrocardiogram (ECG).

    Cohort - I: Injection-related reactions will also be analyzed. Cohort - II: Skin related AEs by regular skin examinations and centralized dermatological monitoring.


  3. 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 assess the effects of CAD106 and CNP520, vs. respective placebo on cognition as measured by changes on the Total Scale score and individual neurocognitive domain index scores of the RBANS.

  4. Change in the Everyday Cognition scale (ECog) total scores [ Time Frame: Baseline to Month 60 ]
    To assess the effects of CAD106 and CNP520, vs. respective placebo on function as measured by the change in ECog total score reported by the participant and study partner, respectively.

  5. Change in Alzheimer's Disease related biomarkers [ Time Frame: Baseline to Months 24 and 60 ]

    To assess the effects of CAD106 and CNP520, vs. respective placebo on AD-related biomarkers (amyloid deposition and measures of neurodegeneration) as measured by changes on:

    amyloid tracer and tau tracer obtained using brain positron emission tomography (PET) imaging, volumetric MRI measurements, and CSF Aβ40, Aβ42, total tau and phosphorylated tau181 levels.


  6. Change in APCC Test Score [ Time Frame: Month 6 to Month 60 ]
    To assess the effects of antibody response to CAD106 vs. placebo on cognition as measured by changes on the APCC test score

  7. Change in CDR-SOB [ Time Frame: Month 6 to Month 60 ]
    To assess the effects of antibody response to CAD106 vs. placebo on cognition as measured by changes on the CDR-SOB.

  8. Aβ-specific immune response [ Time Frame: Through study completion, an average of 5 years ]
    To describe serological immune response to CAD106 injections as measured by Aβ-specific antibody titers generated

  • A positive drug screen at Screening, if, in the Investigator's opinion, this is due to drug abuse.
  • Significantly abnormal laboratory results at Screening, or infection not as a result of a temporary condition.
