入选标准

  • Key Inclusion Criteria for Mild Cognitive Impairment due to Alzheimer's Disease
  • - Intermediate likelihood:
  • 1.Subjects who meet the National Institute of Aging - Alzheimer's Association (NIA-AA) core clinical criteria for mild cognitive impairment due to Alzheimer's disease - intermediate likelihood
  • 2.Subjects who have a CDR score of 0.5 and a Memory Box score of 0.5 or greater at Screening and Baseline
  • 3.Subjects who report a history of subjective memory decline with gradual onset and slow progression over the last one year before Screening; MUST be corroborated by an informant
  • Key Inclusion Criteria for Mild Alzheimer's Disease Dementia:
  • 4.Subjects who meet the NIA-AA core clinical criteria for probable Alzheimer's disease dementia
  • 5.Subjects who have a CDR score of 0.5-1.0 and a Memory Box score of 0.5 or greater at Screening and Baseline
  • Inclusion Criteria that must be met by all subjects:
  • 6.Subjects with objective impairment in episodic memory as indicated by at least 1 standard deviation below age-adjusted mean in the Wechsler Memory Scale - IV Logical Memory II (WMS-IV LMII):
  • a.Less than or equal to 15 for age 50 to 64 years
  • b.Less than or equal to 12 for age 65 to 69 years
  • c.Less than or equal to 11 for age 70 to 74 years
  • d.Less than or equal to 9 for age 75 to 79 years
  • e.Less than or equal to 7 for age 80 to 90 years
  • 7.Positive amyloid load as indicated by PET or CSF assessment
  • 8.Age between 50 and 90 years, inclusive
  • 9.Mini Mental State Examination (MMSE) score equal to or greater than 22, and equal to or less than 30, at Screening and Baseline
  • 10.Body Mass Index (BMI) greater than 17 and less than 35 at Screening
  • 11.Females must not be pregnant or lactating, and specified contraceptive precautions must be followed
  • 12.Subjects on acetylcholinesterase inhibitor or memantine therapy for Alzheimer's disease (AD) must be on a stable dose for at least 12 weeks prior to baseline
  • 13.Subjects must have identified caregivers/informants
  • 14.Subjects must provide written informed consent

排除标准

  • 1.Any neurological condition that may be contributing to cognitive impairment above and beyond that caused by the subject's AD
  • 2.History of transient ischemic attacks (TIA), stroke, or seizures within 12 months of Screening
  • 3.Any psychiatric diagnosis or symptoms, (e.g., hallucinations, major depression, or delusions) that could interfere with study procedures in the subject
  • 4.Contraindications to MRI scanning, including cardiac pacemaker/ defibrillator, ferromagnetic metal implants, e,g., in skull and cardiac devices other than those approved as safe for use in MR scanners
  • 5.Evidence of other clinically significant lesions that could indicate a dementia diagnosis other than AD on brain MRI at Screening, or other significant pathological findings on brain MRI at Screening
  • 6.A prolonged QT/QTc interval (QTc greater than 450 ms) as demonstrated by a repeated electrocardiogram (ECG)
  • 7.Certain other specified medical conditions
  • 8.Severe visual or hearing impairment that would prevent the subject from performing psychometric tests accurately
