Title: A Single Center, Double-Blind, Placebo-Controlled Study to Examine the Safety and Efficacy of Pimavanserin for the Treatment of Psychosis in Alzheimer's Disease
Brief Summary: This study will evaluate the safety and efficacy of pimavanserin 40 mg compared to placebo in patients with Alzheimer's disease psychosis.


Options:
A: Inclusion Criteria:

* Male and female subjects 55 to 90 years of age, inclusive, at the time of informed consent.
* Subjects who are residing at their current location for at least 14 days before screening and are expected to remain at the same location for the duration of the trial.
* Subjects with diagnosis of probable Alzheimer's disease according to NINCDS-ADRDA criteria.
* Subjects with a MMSE score of 5 to 22, inclusive, at screening and baseline visits.
* Subjects with onset of symptoms of agitation at least 2 weeks prior to the screening visit.
* Subjects with a total score greater than or equal to 4 on the agitation aggression item of the NPI-NH or NPI/NPI-NH at the screening and baseline visits.
* Subjects who require pharmacotherapy for the treatment of agitation per the investigator's judgement, after an evaluation of reversible factors (eg, pain, infection, polypharmacy) and a trial of nonpharmacological interventions.
* Subjects must have a previous MRI or CT scan of the brain, which was performed after the onset of symptoms of dementia, with findings consistent with the diagnosis of Alzheimer's disease.

Exclusion Criteria:

* Subjects with dementia or other memory impairment not due to Alzheimer's disease.
* Subjects with history of stroke, well-documented transient ischemic attack, or pulmonary or cerebral embolism.
* Subjects who currently have clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, gastrointestinal, or psychiatric disorders.
* Subjects who have been diagnosed with an Axis I disorder (DSM-IV-TR criteria).
* Subjects with uncontrolled hypertension.
* Subjects with uncontrolled insulin-dependent diabetes mellitus (IDDM)
* Subjects with epilepsy or a history of seizures.
* Subjects considered in poor general health based on the investigator's judgment.
B: Inclusion Criteria:

* Institutionalized patients with Alzheimer's
C: Inclusion Criteria:

* Patient must be 50 years of age or older with NINCDS-ADRDA defined possible or probable AD
* Patient must have psychotic symptoms that developed after the diagnosis of AD was established. These symptoms must include visual and/or auditory hallucinations, and/or delusions
* Patient must have been a nursing home resident for ≥ 4 weeks prior to randomization, not bedridden and expected to remain in the facility throughout the study
* Patient must have actively experienced and verbally communicated psychotic symptoms during the month prior to the Screening visit and weekly during the previous 2 weeks prior to Baseline
* If patient is on acetylcholinesterase inhibitor (AChEI) therapy and/or memantine, must be on stable doses for 3 months prior to the Baseline visit and during the study
* Patient is willing and able to provide informed consent. If the subject is unable to provide written consent due to the severity of dementia, consent must be given by a legally authorized representative

Exclusion Criteria:

* Patient has a history of significant psychotic disorders prior to or concomitantly with the diagnosis of Alzheimer's disease including, but not limited to, schizophrenia or bipolar disorder
* Patient is unable to communicate verbally
* Patient has current evidence of a serious and/or unstable cardiovascular, respiratory, gastrointestinal, renal, hematologic or other medical disorder, including cancer or malignancies, which would affect the patient's ability to participate in the study
* Patient has had a myocardial infarction in the last six months
* Patient has moderate to severe congestive heart failure
* Patient has any surgery planned during the screening, treatment, or follow-up periods that could interfere with participation in the study per the protocol assessments

Patients will be evaluated at screening to ensure that all criteria for study participation are met. These evaluations will include specific measures of psychosis severity, delirium, dementia, cardiovascular condition, and pregnancy status. Patients may be excluded from the study based on these assessments (and specifically if it is determined that their baseline health and psychiatric condition do not meet all protocol-specified entry criteria).
D: Inclusion Criteria:

* Male and female participants 55 to 90 years of age, inclusive, at the time of informed consent.
* Participants who are residing at their current location for at least 14 days before screening and are expected to remain at the same location for the duration of the trial.
* Participants with a diagnosis of probable Alzheimer's disease according to National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association.
* Participants with a Mini-Mental State Exam score of 5 to 22, inclusive, at screening and baseline visits.
* Participants with onset of symptoms of agitation at least 2 weeks prior to the screening visit.
* Participants with a score of ≥ 4 on the agitation/aggression item of the Neuropsychiatric Inventory-Nursing Home at the screening and baseline visits.
* Participants who require pharmacotherapy for treatment of agitation per the investigator's judgment, after an evaluation for reversible factors (for example, pain, infection, polypharmacy) and a trial of nonpharmacological intervention.
* Participants must have a previous magnetic resonance imaging or computed tomography of the brain, which was performed after the onset of symptoms of dementia, with findings consistent with the diagnosis of Alzheimer's disease.

Exclusion Criteria:

* Participants with dementia or other memory impairment not due to Alzheimer's disease
* Participants with a history of stroke, well-documented transient ischemic attack, pulmonary or cerebral embolism.
* Participants who currently have clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, gastrointestinal, or psychiatric disorders.

* Participants with uncontrolled hypertension
* Participants with uncontrolled insulin-dependent diabetes mellitus
* Participants with epilepsy or a history of seizures
* Participants considered in poor general health based on the investigator's judgment.
