Who the study is looking for
- Participant and/or Caregiver must provide a signed and dated ICF prior to any study procedures.
- Must have a Caregiver who is able and willing to comply with all required study procedures.
- The Caregiver must be known to the Participant and must be able to use electronic devices such as a cell phone, video conference over a laptop or cell phone, weighing scale, and be able to learn to take blood pressure, among others.
- Based on local practice, Participants that cannot consent may have Caregiver's consent provided the Caregiver has among others a) Power of Attorney, b) is a spouse, or c) a sibling or d) a child or e) a close relation.

- Diagnosis of AD by NIA-AA criteria
- Clinically significant Agitation assessed by:
- NPI (Agitation) ≥ 4
- The presence of clinically significant, persistent Agitation based on the IPA definition (Appendix C) rather than those with recent onset and occasional symptoms, and
- Agitation not attributable to another psychiatric disorder, suboptimal care conditions, other underlining medical condition, or the physiological effects of a substance.
- Negative drug screen, except for benzodiazepines if Participant has been using them in stable doses for at least 3 months before screening.
- All medications used for behavioral symptoms should be consistent for at least 6 weeks before screening, with allowance for dose changes up to 25%.
