入选标准

  • Pre-screening Epoch and Genetic Disclosure Follow-up inclusion criteria1.
  • Written informed consent (Informed consent #1) obtained before any assessment
  • is performed, including consent to receive disclosure of their APOE genotype.
  • 2. Male or female, age 60 to 75 years inclusive, at the time of signing the
  • informed consent #1 (same age restriction also applied at informed consent #2).
  • a. Once the cap of approximately 20% of total participants in the age group 60-
  • 64 years is met, a restriction to this age group will apply.
  • 3. Females must be considered post-menopausal and not of child bearing
  • potential. Confirmation will be obtained for those who continue on to the
  • Screening Epoch.
  • 4. Mini-Mental State Examination (MMSE) total score * 24 (can be based on
  • documented result obtained i previous 3 months).
  • 5. Psycholgical readiness to receive APOE genotype information based on
  • pre-disclosure rating scales:
  • a. Geriatric Depression Scale (GDS short form) total score *6.
  • If the score is between 7 and 10 (inclusive), the participant can only be
  • included based on investigator*s judgment assessing in particular the scores
  • of the questions:
  • i. Item 3: *Do you feel your life is empty?*
  • ii. Item 6: *Are you afraid that something bad is going to happen to you?*
  • iii. Item 12: *Do you feel pretty worthless the way you are now?*
  • iv. Item 14: *Do you feel your situation is hopeless?*
  • b. Six Item Subset Inventory of the STAI-AD total score *17.
  • If the score is 18 or 19, the participant can only be included based on the
  • investigator*s judgment.
  • 6. Participant is fluent in, and able to read the language in which the study
  • are administered (e.g. completion of at least 6 years of regular schooling or
  • sustained employment).
  • 7. Participant*s willingness to have a study partner for the Screening and
  • Treatment epoch.
  • Screening and Treatment Epoch inclusion criteriaParticipants eligible for
  • inclusion must fulfill all of the following criteria prior to randomization:
  • 1. Written informed consent (Informed consent #2) for participation to the
  • Screening and Treatment Epochs (participant must still be between 60-75 years,
  • inclusive at the time of signing ICF #2; respectively 65-75 after reaching the
  • maximum of 20% in the ypunger age group 60-64).
  • 2. Continue to meet all eligibility criteria from Pre-screening Epoch and
  • Genetic Disclosure Follow-up, as confirmed by the review of the medical records
  • by the Investigator.
  • 3. Homozygous APOE4 genotype.
  • 4. Cognitively unimpaired as defined by:
  • * At the screening visit, score of 85 or greater on the RBANS delayed memory
  • index score
  • * CDR global score of 0
  • with two exceptions:
  • ­ If the RBANS delayed memory index score is between 70 and 84 (inclusive) AND
  • the global CDR score <= 0, the participant may be allowed to continue ONLY if
  • the Investigator judges that cognition is unimpaired following review of the
  • MCI/dementia criteria.
  • ­ If the global CDR score <= 0.5 AND the RBANS delayed memory index score is 85
  • 另有 5 项未显示

排除标准

  • Pre-screening Epoch and Genetic Disclosure Follow-up exclusion criteria1. Any
  • disability that may prevent the participants from completing all study
  • requirements (e.g., blindness, deafness, severe language difficulty).
  • 2. Current medical or neurological condition that might impact cognition or
  • performance on cognitive assessments.
  • 3. Advanced, severe progressive or unstable disease that may interfere with the
  • safety, tolerability and study assessments, or put the participant at special
  • 4. History of malignancy of any organ system, treated or untreated, within the
  • past 60 months, regardless of whether there is evidence of local recurrence or
  • metastases. However, localized nonmalignant tumors not requiring systemic
  • chemo- or radio-therapy, localized basal or squamous cell carcinoma of the
  • skin, in-situ cervical cancer, localized vulvar carcinoma and localized
  • prostate carcinoma with no progression over the past two years are permitted.
  • 5. History of hypersensitivity to any of the investigational drugs or their
  • excipients/adjuvant, or to drugs of similar chemical classes.
  • 6. Indication for or current treatment with ChEIs and/or another AD treatment
  • (e.g. memantine).
  • 7. Contraindication or intolerance to MRI or PET investigations.Screening and
  • Treatment Epoch exclusion criteria
  • Participants fulfilling any of the following criteria prior to randomization
  • will be excluded.
  • Participants, who fulfill one or more exclusion criteria due to a temporary
  • condition, or the use of treatment requiring a specific time window prior to
  • randomization, can be re-screened at a later stage:
  • 1. Brain MRI results from the central reading showing findings unrelated to AD
  • that, in the opinion of the Investigator might be a leading cause of future
  • cognitive decline, might pose a risk to the participant, or might confound MRI
  • assessment for safety monitoring.For Cohort I (CAD 106) only, in addition,
  • evidence of ARIA-H as demonstrated by:
  • * More than four cerebral microhemorrhages (defined as diameter * 10 mm on T2*
  • sequence) regardless of their anatomical location
  • * Single area of superficial siderosis of the CNS or evidence of a prior
  • cerebral macrohemorrhage (> 10 mm diameter)
  • 2. Score *yes* on item four or item five of the Suicidal Ideation Section of
  • the C-SSRS if this ideation occurred in the past six months, or *yes* on any
  • item of the Suicidal Behavior Section, except for the *Non-Suicidal
  • Self-Injurious Behavior* (item also included in the Suicidal Behavior Section)
  • if this behavior occurred in the past two years prior to screening.
  • 3. A positive drug screen at Screening, if, in the Investigator*s opinion, this
  • is due to drug abuse. Participants with a positive drug screen not believed to
  • be related to drug abuse (e.g. presence of prescription drugs in urine without
  • evidence of prescription drug abuse), can be re-screened once.
  • 4. Significantly abnormal laboratory results at Screening as described in
  • appendix 13.4 or meeting the exclusionary alert values specified in the
  • Laboratory Manual. If, in the opinion of the Investigator, an abnormal finding
  • is the result of a temporary condition, the laboratory test can be repeated
  • 5. Clinically significant active infection which has not resolved wiothin 2
  • weeks prior to initial dosing.
  • 6. Current clinically significa
