Study Details

Study Description

Brief Summary

The purpose of this study was to test whether two investigational drugs called CAD106 and CNP520, administered separately, could 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
  • Biological: CAD106 Immunotherapy
  • Other: Placebo to CAD106
  • Drug: CNP520
  • Other: Placebo to CNP520
  • Other: Alum
Phase 2/Phase 3

Detailed Description

The study (also known as the Generation Study 1, GS1) was conducted as part of the Alzheimer's Prevention Initiative (API) program.

This trial was a randomized, double-blind, placebo-controlled, parallel group, adaptive design with variable treatment duration planned in cognitively unimpaired APOE4 homozygotes (HMs) aged 60 to 75 years. Participants were enrolled into Cohort I (CAD106) or Cohort II (CNP520).

The planned treatment period of 5 to 8 years was not achieved due to early study termination.

The study was terminated due to unexpected changes in cognitive function, brain volume loss, and body weight loss. Cohort II (CNP520) treatment was stopped and evaluated through an off-treatment follow-up period. After the decision to terminate Cohort II of the study (CNP520), treatment with CAD106 (Cohort I) was also terminated.

Outcome Measures

Primary Outcome Measures

  1. Time to Event (Diagnosis of Mild Cognitive Impairment or Dementia, Due to Alzheimer's Disease (AD)) [Baseline to end of exposure for a maximum of 1455 days for CI and 907 days for CII]

    Event was defined as the first confirmed diagnosis of MCI due to Alzheimer's disease (AD) or dementia due to AD (whichever occurred first) after adjudication by the progression adjudication committee (PAC) as triggered either by an investigator diagnosis or an increase in the Clinical Dementia Rating (CDR) global score. An event had to be confirmed by the PAC at two consecutive visits. In case no confirmed event was observed for a participant, the observation was censored, and the censoring date was defined as the last date where the diagnostic classification was assessed. The Study was terminated and only confirmed events collected up to the data cut-off point were counted. Due to the early termination of the study only a small number of events were observed and time-to-event could not be analyzed. Kaplan-Meyer (KM) estimates were provided to estimate probability that a subject would have an event prior to the specified visit.

  2. Change in the Alzheimer's Prevention Initiative Composite Cognitive (APCC) Test Score [CI = Baseline to Weeks 26, 52,78 104 and Baseline to last assessment; CII = Baseline to Weeks 26, 52, 78, 104 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    APCC is a composite score derived from the specific scores from the Repeatable Battery for the Assessment of Neurological Status (RBANS), Mini-Mental State Examination (MMSE) and the Raven's Progressive Matrices. The APCC score is a weighted score with ranges from from 0 to 100 where higher scores correspond to better cognitive performance.

Secondary Outcome Measures

  1. Change in Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) Score [CI = Baseline to Weeks 26, 52,78 104 and Baseline to last assessment; CII = Baseline to Weeks 26, 52, 78, 104 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    The CDR was obtained through semi-structured interviews of participants and informants, and cognitive functioning was rated on a 5-point scale of functioning in six domains: memory, orientation, judgement and problem solving, community affairs, home and hobbies, and personal care. The CDR global score ranged from zero to three, while the CDR-SOB was the sum of the ratings from the six domains, ranging from 0 to 18 with a minimum increment of 0.5. Higher scores indicated greater disease severity.

  2. Change in the Total Scores of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). [CI = Baseline to Weeks 26, 52,78 104 and Baseline to last assessment; CII = Baseline to Weeks 26, 52, 78, 104 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    Repeatable Battery for the Assessment of Neurological Status (RBANS) is a clinical tool designed to detect and characterize the earliest neurocognitive changes associated with dementia. The RBANS generates age-adjusted index scores for five neurocognitive domains: Immediate Memory, Visuospatial/Constructional, Language, Attention and Delayed Memory, which are used to calculate a Total Scale Index score. Index scores and total score range from 40 to 160 and a higher score indicates better cognitive functioning.

  3. Change in the Index Scores of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). [CI = Baseline to Weeks 26, 52 and Baseline to last assessment; CII = Baseline to Weeks 26, 52 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    Repeatable Battery for the Assessment of Neurological Status (RBANS) is a clinical tool designed to detect and characterize the earliest neurocognitive changes associated with dementia. The RBANS generates age-adjusted index scores for five neurocognitive domains: Immediate Memory, Visuospatial/Constructional, Language, Attention and Delayed Memory, which are used to calculate a Total Scale Index score. Index scores and total score range from 40 to 160 and a higher score indicates better cognitive functioning.

  4. Change in the Everyday Cognition Scale (ECog-Subject) Total Scores [CI = Baseline to Weeks 26, 52 and Baseline to last assessment; CII = Baseline to Weeks 26, 52 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    Everyday Cognition Scale (ECog) measures cognitively-relevant everyday abilities comprised of 39 items covering 6 cognitively-relevant domains: Everyday Memory, Everyday Language, Everyday Visuospatial Abilities, Everyday Planning, Everyday Organization, and Everyday Divided Attention. The questionnaire is a self-reported measure completed by both participant and study partner (informant). The total score for the 39 items ranges from 39 to 195, with greater scores indicating worse daily function.

  5. Change in the Everyday Cognition Scale (ECog-Informant) Total Scores [CI = Baseline to Weeks 26, 52 and Baseline to last assessment; CII = Baseline to Weeks 26, 52 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    Everyday Cognition Scale (ECog) measures cognitively-relevant everyday abilities comprised of 39 items covering 6 cognitively-relevant domains: Everyday Memory, Everyday Language, Everyday Visuospatial Abilities, Everyday Planning, Everyday Organization, and Everyday Divided Attention. The questionnaire is a self-reported measure completed by both participant and study partner (informant). The total score for the 39 items ranges from 39 to 195, with greater scores indicating worse daily function. Cohort I=C I and Cohort II=C II.

  6. Number of Participants With Newly Occurring Safety MRI Abnormalities (ARIA-E, ARIA-H,White Matter Disease and Any Other MRI Abnormalities) [Baseline to end of exposure for a maximum of 1455 days for CI and 907 days for CII]

    Safety MRI included sequences necessary for ascertainment of possible ARIA-E (Amyloid Related Imaging Abnormality-Edema), ARIA-H (Amyloid Related Imaging Abnormality- Hemorrhage, including superficial siderosis and microhemorrhages), assessment of recent infarcts and white matter integrity examination (White matter disease worsening since baseline) and a general assessment of brain abnormalities. Assessment of cerebral amyloid angiopathy (CAA) is included in the overall safety MRI findings results.

  7. Annualized Percent Change on Volume of Brain Regions [CI = Baseline to Weeks 26, 52 and Baseline to last assessment; CII = Baseline to Weeks 26, 52 and Baseline to Last on-treatment and Baseline to Last off-treatment]

    Annualized % change from baseline in volume of specific brain regions of interest (ROIs): whole brain (WB), hippocampus (Hip), and lateral ventricles (LV). Annualized percentage change was calculated as (percentage per participant / time interval (in days)) x 365.25. Time interval (in days) was derived as date of current MRI assessment on study drug - date of baseline MRI assessment + 1.

  8. Change in Cerebrospinal Fluid (CSF) Levels of Amyloid Beta 40 (Aβ40) [Baseline to last assessment]

    Alzheimer's Disease-related biomarkers analyzed in cerebrospinal fluid (CSF): Amyloid Beta 40 (Aβ40)

  9. Change in Cerebrospinal Fluid (CSF) Levels of Amyloid Beta 42 (Aβ42) [Baseline to last assessment]

    Alzheimer's Disease-related biomarkers analyzed in cerebrospinal fluid (CSF): Amyloid Beta 42 (Aβ42)

  10. Change in Cerebrospinal Fluid (CSF) Levels of Total Tau and Phosphorylated Tau [Baseline to last assessment]

    Alzheimer's Disease-related biomarkers analyzed in cerebrospinal fluid (CSF): total tau protein and phosphorylated tau protein levels

  11. Change in Neurofibrillary Tangle Burden as Measured by Standardized Uptake Ratio (SUVR) of PET Scans With Tau Radiotracer (Where Available) [Baseline to last assessment]

    To demonstrate the effects of CNP520 vs placebo on tau pathology in the brain

  12. Cohort I : Annualized Change in Amyloid Deposition as Measured by Centiloids of Positron Emission Tomography (PET) Scan With Amyloid Radiotracer [Baseline up to approximately Week 104]

    To demonstrate the effects of CAD106 vs placebo on Alzheimer's Disease-related biomarkers

  13. Change in Serum Neurofilaments [Baseline to Week 26 and week 52, CI baseline to last assessment. CII baseline to last on-treatment and to last off-treatment]

    Alzheimer's Disease-related biomarkers analyzed in blood serum: light chain neurofilaments (NfL)

  14. Number of Suicidal Ideation or Behavior Events [Baseline to end of exposure for a maximum of 1455 days for CI and 907 days for CII]

    Prospective suicidality assessment was performed with the use of Columbia-Suicide Severity Rating Scale (C-SSRS), a questionnaire using a detailed branched logic algorithm evaluating participant's suicidality ideation and behavior. Answer "yes" on item 4 or 5 of the Suicidal Ideation section or "yes" on any item of the Suicidal Behavior section was considered positive.

  15. Cohort I : Change in Cognition as Measured by APCC and CDR-SOB Scores and Antibody Response [Month 6 to Month 60]

  16. Cohort I: Peak Concentration (Cmax) of CAD106 Induced Abeta-specific Antibody Titers [Week 9, 13, 15, 26 and quarterly thereafter (trough values)]

    Cmax is the maximum Titer Concentration of any post-baseline 'on treatment' visit. A visit is considered as 'on treatment' if visit date is within {last injection + 180 days}. - Geometric mean and CI's are back-transformed from the estimates for Log mean and CI's.

  17. Cohort I: Area Under the Concentration Curve (AUC) of CAD106 Induced Abeta-specific Antibody Titers [Week 9, 13, 15, 26 and quarterly thereafter (trough values)]

    AUC is calculated based on 'on treatment' visit only.(missing values for peak visits were linearly interpolated for calculation; missing values for trough visits were imputed by average of non-missing trough values.).

Outcome Measures

1. Primary Outcome
Title Time to Event (Diagnosis of Mild Cognitive Impairment or Dementia, Due to Alzheimer's Disease (AD))
Description Event was defined as the first confirmed diagnosis of MCI due to Alzheimer's disease (AD) or dementia due to AD (whichever occurred first) after adjudication by the progression adjudication committee (PAC) as triggered either by an investigator diagnosis or an increase in the Clinical Dementia Rating (CDR) global score. An event had to be confirmed by the PAC at two consecutive visits. In case no confirmed event was observed for a participant, the observation was censored, and the censoring date was defined as the last date where the diagnostic classification was assessed. The Study was terminated and only confirmed events collected up to the data cut-off point were counted. Due to the early termination of the study only a small number of events were observed and time-to-event could not be analyzed. Kaplan-Meyer (KM) estimates were provided to estimate probability that a subject would have an event prior to the specified visit.
Time Frame Baseline to end of exposure for a maximum of 1455 days for CI and 907 days for CII

Title Change in Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) Score
Description The CDR was obtained through semi-structured interviews of participants and informants, and cognitive functioning was rated on a 5-point scale of functioning in six domains: memory, orientation, judgement and problem solving, community affairs, home and hobbies, and personal care. The CDR global score ranged from zero to three, while the CDR-SOB was the sum of the ratings from the six domains, ranging from 0 to 18 with a minimum increment of 0.5. Higher scores indicated greater disease severity.

Title Change in the Total Scores of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).
Description Repeatable Battery for the Assessment of Neurological Status (RBANS) is a clinical tool designed to detect and characterize the earliest neurocognitive changes associated with dementia. The RBANS generates age-adjusted index scores for five neurocognitive domains: Immediate Memory, Visuospatial/Constructional, Language, Attention and Delayed Memory, which are used to calculate a Total Scale Index score. Index scores and total score range from 40 to 160 and a higher score indicates better cognitive functioning.
