* 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 participants in Japan
* 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
* Participants who have completed the Core Study (except de novo participants)
* 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 entering the subcutaneous (vial) substudy at Extension Phase Week 1, must be willing to participate, or continue participating in the amyloid positron emission tomography (PET) substudy. All participants must have an amyloid PET scan within 4 weeks before starting subcutaneous BAN2401
* Participants enrolling into the subcutaneous autoinjector substudy must have had at least 6 months exposure to BAN2401 10 mg/kg intravenously biweekly or BAN2401 Dose 1 subcutaneously weekly.
* Participants enrolling into the subcutaneous Dose 3 autoinjector substudy must have previously received BAN2401 by either intravenous administration and/or subcutaneous autoinjector administration and must have completed Visit 82 (Extension Week 79) at a minimum, regardless of previous route of administration
• Must have completed Week 207 in the Extension Phase
Exclusion Criteria
* History of transient ischemic attacks (TIA), stroke, or seizures within 12 months of Screening

* 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
* Participants with a bleeding disorder that is not under adequate control (including a platelet count \<50,000 or international normalized ratio \[INR\] \>1.5 for participants who are not on anticoagulant treatment, example, warfarin). Participants who are on anticoagulant therapy should have their anticoagulant status optimized and be on a stable dose for 4 weeks before Screening. Participants who are on anticoagulant therapy are not permitted to participate in cerebrospinal fluid (CSF) assessments
* 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

* Contraindications to MRI scanning, including cardiac pacemaker/defibrillator, ferromagnetic metal implants (example, in skull and cardiac devices other than those approved as safe for use in MRI scanners)
* Other significant pathological findings on brain MRI during the Core Study including but not limited to: 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 will be exclusionary if based on the opinion of the investigator, with consultation of medical monitor, these findings may interfere with the study procedures or safety
* Hypersensitivity to BAN2401 or any of the excipients, or to any monoclonal antibody treatment
* Any immunological disease which is not adequately controlled, or which requires chronic treatment with immunoglobulins, systemic monoclonal antibodies (or derivatives of monoclonal antibodies), systemic immunosuppressants, or plasmapheresis during the study
* Any other clinically significant abnormalities in physical examination, vital signs, laboratory tests, or ECG, which in the opinion of the investigator require further investigation or treatment or which may interfere with study procedures or safety
* Malignant neoplasms (except for basal or squamous cell carcinoma in situ of the skin, or localized prostate cancer in male participants) that are not stably and adequately controlled or which, based on the opinion of the investigator, may interfere with the participant's safety or participation in the study
* 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
