resubmitted NUPLAZID (pimavanserin) supplemental New Drug
Application for the treatment of hallucinations and delusions
associated with Alzheimer’s disease psychosis.

About Alzheimer’s Disease Psychosis
According to the Alzheimer’s Association, approximately six
million people in the United States are living with Alzheimer’s
disease (AD).1-2 Approximately 30% of patients with AD experience
psychosis, commonly consisting of hallucinations and delusions.3
These symptoms may be frequent and severe and may recur over time.4
A hallucination is defined as a perception-like experience that
occurs without an external stimulus and is sensory (seen, heard,
felt, tasted, sensed, smelled) in nature. A delusion is defined as
a false, fixed belief despite evidence to the contrary. Serious
consequences have been associated with psychosis in patients with
dementia, such as increased likelihood of nursing home placement,
more severe dementia, and increased risk of morbidity and
mortality.5-6 There is no FDA approved drug for the treatment of
Alzheimer’s disease psychosis.
About Pimavanserin
Pimavanserin is a selective serotonin inverse agonist and
antagonist preferentially targeting 5-HT2A receptors. These
receptors are thought to play an important role in neuropsychiatric
disorders. In vitro, pimavanserin demonstrated no appreciable
binding affinity for dopamine (including D2), histamine,
muscarinic, or adrenergic receptors. Pimavanserin was approved for
the treatment of hallucinations and delusions associated with
Parkinson’s disease psychosis by the U.S. Food and Drug
Administration in April 2016 under the trade name NUPLAZID®.
NUPLAZID is not approved for Alzheimer’s disease psychosis. In
addition, Acadia is developing pimavanserin in other
neuropsychiatric conditions.

Important Safety Information and Indication for NUPLAZID®
(pimavanserin)
Indication
NUPLAZID is indicated for the treatment of hallucinations and
delusions associated with Parkinson’s disease psychosis.
Important Safety Information
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH
DEMENTIA-RELATED PSYCHOSIS
- Elderly patients with dementia-related psychosis treated
with antipsychotic drugs are at an increased risk of
death.
- NUPLAZID is not approved for the treatment of patients with
dementia-related psychosis unrelated to the hallucinations and
delusions associated with Parkinson’s disease psychosis.
Contraindication: NUPLAZID is contraindicated in patients
with a history of a hypersensitivity reaction to pimavanserin or
any of its components. Rash, urticaria, and reactions consistent
with angioedema (e.g., tongue swelling, circumoral edema, throat
tightness, and dyspnea) have been reported.
Warnings and Precautions: QT Interval Prolongation
- NUPLAZID prolongs the QT interval. The use of NUPLAZID should
be avoided in patients with known QT prolongation or in combination
with other drugs known to prolong QT interval including Class 1A
antiarrhythmics or Class 3 antiarrhythmics, certain antipsychotic
medications, and certain antibiotics.
- NUPLAZID should also be avoided in patients with a history of
cardiac arrhythmias, as well as other circumstances that may
increase the risk of the occurrence of torsade de pointes and/or
sudden death, including symptomatic bradycardia, hypokalemia or
hypomagnesemia, and presence of congenital prolongation of the QT
interval.
Adverse Reactions: The common adverse reactions (≥2% for
NUPLAZID and greater than placebo) were peripheral edema (7% vs
2%), nausea (7% vs 4%), confusional state (6% vs 3%), hallucination
(5% vs 3%), constipation (4% vs 3%), and gait disturbance (2% vs
<1%).
Drug Interactions:
- Coadministration with strong CYP3A4 inhibitors (e.g.,
ketoconazole) increases NUPLAZID exposure. Reduce NUPLAZID dose to
10 mg taken orally as one tablet once daily.
- Coadministration with strong or moderate CYP3A4 inducers
reduces NUPLAZID exposure. Avoid concomitant use of strong or
moderate CYP3A4 inducers with NUPLAZID.
Dosage and Administration
Recommended dose: 34 mg capsule taken orally once daily, without
titration.
NUPLAZID is available as 34 mg capsules and 10 mg tablets.
