- Patients who discontinued treatment permanently in Study BN29552 or BN29553 for safety reasons.
- Impaired coagulation.
- Evidence of more than 10 microbleeds and/or ARIA-H (amyloid-related imaging abnormalities-hemosiderin deposition) at the Study BN29552 or BN29553 Week 105 visit, as assessed by central review of MRI.
- Diagnosed with three recurrent, symptomatic ARIA-E (amyloid-related imaging abnormalities-edema/effusion) events or exacerbations of previous events.

- Pregnant or lactating, or intending to become pregnant during the study.
- Any other severe or unstable medical condition that, in the opinion of the investigator or Sponsor, could be expected to progress, recur, or change to such an extent that it could put the patient at special risk, bias the assessment of the clinical or mental status of the patient to a significant degree, or interfere with the patient's ability to complete the study assessments.
