Brief Summary:
This is an open-label, multicenter, rollover study to evaluate the safety and tolerability of long-term administration of gantenerumab in participants with AD.

  • Any medical condition that may jeopardize the participant's safety if he or she continues to receive study treatment
  • If the participant is unlikely to benefit from gantenerumab therapy, based on disease progression or other factors, or if study participation is otherwise not in the participant's best interest
  • Any investigational treatment other than gantenerumab during or since completion of the OLEs of studies WN25203 or WN28745
  • Pregnancy
  • Evidence of disseminated leptomeningeal hemosiderosis (i.e., more than three focal leptomeningeal hemosiderosis)
