Brief Summary:
This study will be conducted to evaluate the efficacy of BAN2401 in participants with early Alzheimer's disease (EAD) by determining the superiority of BAN2401 compared with placebo on the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 18 months of treatment in the Core Study. This study will also evaluate the long-term safety and tolerability of BAN2401 in participants with EAD in the Extension Phase and whether the long-term effects of BAN2401 as measured by the CDR-SB at the end of the Core Study is maintained over time in the Extension Phase.

Ages Eligible for Study:   50 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Core Study: Inclusion Criteria

Diagnosis: Mild Cognitive Impairment (MCI) due to Alzheimer's disease - intermediate likelihood:

  • Meet the National Institute of Aging - Alzheimer's Association (NIA-AA) core clinical criteria for MCI due to Alzheimer's disease - intermediate likelihood
  • Have a global Clinical Dementia Rating (CDR) score of 0.5 and CDR Memory Box score of 0.5 or greater at Screening and Baseline
  • 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

Mild Alzheimer's disease dementia:

  • Meet the NIA-AA core clinical criteria for probable Alzheimer's disease dementia
  • 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 participants:

  • 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 (subscale) II (WMS-IV LMII)
  • Positive biomarker for brain amyloid pathology
  • Male or female participants aged greater than or equal to (>=) 50 and less than or equal to (<=) 90 years, at the time of informed consent
  • Mini mental state examination (MMSE) score >=22 at Screening and Baseline and <=30 at Screening and Baseline
  • Body mass index (BMI) greater than (>)17 and less than (<) 35 at Screening
  • If receiving an approved Alzheimer's disease treatment such as acetylcholinesterase inhibitor (AChEIs) or memantine or both for Alzheimer's disease, must be on a stable dose for at least 12 weeks prior to Baseline. Treatment-naive participants for Alzheimer's disease can be entered into the study. Unless otherwise stated, participants must have been on stable doses of all other (that is, non-Alzheimer's disease-related) permitted concomitant medications for at least 4 weeks prior to Baseline. Use of memantine will not be allowed for Japanese participants
  • Have an identified study partner (defined as a person able to support the participant for the duration of the study and who spends at least 8 hours per week with the participant)
  • Provide written informed consent. If a participant lacks capacity to consent in the investigator's opinion, the participant's assent should be obtained, if required in accordance with local laws, regulations and customs, plus the written informed consent of a legal representative should be obtained (capacity to consent and definition of legal representative should be determined in accordance with applicable local laws and regulations). In countries where local laws, regulations, and customs do not permit participants who lack capacity to consent to participate in this study (example, Germany and Spain), they will not be enrolled

Extension Phase: Inclusion Criteria:

  • Participants who have completed the Core Study
  • Have a BMI >17 and <35
  • Must continue to have a study partner who is willing and able to provide follow-up information on the participant throughout the course of the Extension Phase
  • Provide written informed consent for the Extension Phase. If a participant lacks capacity to consent in the investigator's opinion, the participant's assent should be obtained, if required and in accordance with local laws, regulations and customs, plus the written informed consent of a legal representative should be obtained (capacity to consent and definition of legal representative should be determined in accordance with applicable local laws and regulations). In countries where local laws, regulations, and customs do not permit participants who lack capacity to consent to participate in this study (example, Germany and Spain), they will not be enrolled

Participants who are on anticoagulant therapy should have their anticoagulant status optimized and be on a stable dose for 4 weeks before Screening
  • Any other medical conditions (example, cardiac, respiratory, gastrointestinal, renal disease) which are not stably and adequately controlled, or which in the opinion of the investigator(s) could affect the participant's safety or interfere with the study assessments
  • Participation in a clinical study involving any therapeutic monoclonal antibody, protein derived from a monoclonal antibody, immunoglobulin therapy, or vaccine within 6 months before screening unless it can be documented that the participant was randomized to placebo
  • Participation in a clinical study involving any anti-amyloid therapies (including any monoclonal antibody therapies and any β-site amyloid precursor protein cleaving enzyme [BACE] inhibitor therapies) unless it can be documented that the participant only received placebo
  • Participants who have any known prior exposure to BAN2401
  • Participants who were dosed in a clinical study involving any new chemical entities for Alzheimer's disease (AD) within 6 months prior to screening unless it can be documented that the participant was in a placebo treatment arm
