入选标准
- •MCI due to AD–intermediate likelihood:
- •1. Meet the NIA-AA core clinical criteria for MCI due to AD–intermediate likelihood.
- •2. Have a global CDR score of 0.5 and a CDR Memory Box score of 0.5 or greater at Screening and Baseline.
- •3. Report a history of subjective memory decline with gradual onset and slow progression over the last 1 year before Screening; must be
- •corroborated by an informant.
- •4. Meet the NIA-AA core clinical criteria for probable AD dementia.
- •5. Have a global CDR score of 0.5 to 1.0 and a CDR Memory Box score of 0.5 or greater at Screening and Baseline.
- •Key Inclusion Criteria that must be met by all subjects:
- •6. 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:
- •a. =15 for age 50-64 years
- •b. =12 for age 65-69 yrs
- •c. =11 for age 70-74 yrs
- •d. =9 for age 75-79 yrs
- •e. =7 for age 80-90 yrs
- •7. Positive biomarker for brain amyloid pathology as indicated by at least 1 of the following:
- •a. PET assessment of imaging agent uptake into brain. Note: amyloid PET screens will be performed according to local regulatory guidelines and thus may be restricted for those subjects who are not suitable for lumbar puncture (LP) to obtain CSF for testing of eligibility.
- •b. CSF assessment of t-tau/Aß[1-42]
- •NOTE1: Subjects who are on anticoagulant therapy may not participate in CSF assessments.
- •NOTE2: Subjects may consent to both the PET and CSF assessments, but to confirm eligibility, a positive amyloid result is needed in only 1 of the 2 procedures (ie, the subject will be eligible even if 1 of the 2 results does not meet its eligibility criterion). Subjects who consent to amyloid PET or CSF at Screening for the purposes of eligibility are not required to participate in the amyloid PET, tau PET, or CSF longitudinal substudies. Use of a historical amyloid positive PET (conducted within 12 months before the planned date of randomization) is acceptable for determination of eligibility provided the subject did not participate in any clinical studies involving anti-amyloid therapies subsequent to the PET assessment. Historical PET will not suffice for the baseline assessment if the subject wishes to consent to the amyloid PET longitudinal substudy. The historical imaging data must be made available to the sponsor to confirm amyloid positivity.
- •8. Male or female subjects aged =50 and =90 years, at the time of
- •informed consent.
- •9. MMSE score greater than or equal to 22 at Screening and Baseline and less than or equal to 30 at Screening and Baseline.
- •10. Body mass index (BMI) greater than 17 and less than 35 at
- •11. If receiving an approved AD treatment, such as AChEIs, or memantine, or both for AD, must be on a stable dose for at least 12
- •weeks prior to Baseline. Treatment-naïve subjects for AD can be entered into the study. Unless otherwise stated, subjects must have been on stable doses of all other (ie, non-AD-related) permitted concomitant medications for at least 4 weeks prior to Baseline. Use of memantine will not be allowed for Japanese subjects.
- •12. Have an identified study partner (defined as a person able to support the subject for the duration of the study and who spends at least 8 hours per week with the subject). The study partner must provide separate written informed consent. In addition, this person must be willing and able to provide follow-up information on the subject throughout the course of the study.

排除标准
- •1. Females who are breastfeeding or pregnant at Screening or Baseline
- •2. Females of childbearing potential who:
- •a. Within 28 days before study entry, did not use a highly effective
- •method of contraception (see protocol for full details)
- •b. Do not agree to use a highly effective method of contraception (as described in the protocol) throughout the entire study period and for 28 days after study drug discontinuation.
- •3. Any neurological condition that may be contributing to cognitive
- •impairment above and beyond that caused by the subject's AD.
- •4. History of transient ischemic attacks, stroke, or seizures within 12
- •months of Screening.
- •5. Any psychiatric diagnosis or symptoms that could interfere with study procedures in the subject.
- •6. GDS score greater than or equal to 8 at Screening.
- •7. Contraindications to MRI scanning, including cardiac pacemaker/defibrillator, ferromagnetic metal implants.
- •8. Evidence of other clinically significant lesions on brain MRI at
- •Screening that could indicate a dementia diagnosis other than AD.
- •9. Other significant pathological findings on brain MRI at Screening,
- •including but not limited to: more than 4 microhemorrhages (defined as 10 mm or less at the greatest diameter); a single macrohemorrhage greater than 10 mm at greatest diameter; an area of superficial siderosis; evidence of vasogenic edema; evidence of cerebral contusion, encephalomalacia, aneurysms, vascular malformations, or infective lesions; evidence of multiple lacunar infarcts or stroke involving a major vascular territory, severe small vessel, or white matter disease; space occupying lesions; or brain tumors (however, lesions diagnosed as meningiomas or arachnoid cysts and less than 1 cm at their greatest diameter need not be exclusionary).
- •10. Hypersensitivity to BAN2401 or any of the excipients, or to any
- •monoclonal antibody treatment.
- •11. Any immunological disease which is not adequately controlled, or which requires treatment with immunoglobulins, systemic monoclonal antibodies (or derivatives of monoclonal antibodies), systemic immunosuppressants, or plasmapheresis during the study.
- •12. Subjects with a bleeding disorder that is not under adequate control (including a platelet count <50,000 or INR >1.5 for subjects who are not on anticoagulant treatment. Subjects who are on anticoagulant therapy should have their anticoagulant status optimized and be on a stable dose for 4 weeks before Screening.
- •Subjects who are on anticoagulant therapy are not permitted to
- •participate in CSF assessments.
- •13. Have thyroid stimulating hormone (TSH) above normal range. Other tests of thyroid function with results outside the normal range should only be exclusionary if they are considered clinically significant by the investigator. This applies to all subjects whether or not they are taking thyroid supplements.
- •14. Abnormally low serum vitamin B12 levels for the testing laboratory
- •15. Known to be HIV positive.
- •16. Any other clinically significant abnormalities in physical examination, vital signs, laboratory tests, or ECG at Screening or Baseline which in the opinion of the investigator require further investigation
- •17. Subjects with malignant neoplasms within 3 years of Screening (see protocol for exceptions).
