Pimavanserin for Psychological Symptoms of Dementia

Start: May 21, 2018
End: May 6, 2022
Enrollment: 750

What Is This Study About?

Anxiety, mood swings, risk-taking, and apathy are some of the psychological symptoms experienced by people with dementia. This Phase 3 study will test whether pimavanserin, an antipsychotic drug approved to treat hallucinations and delusions in people with psychosis from Parkinson's disease, is effective in reducing psychological symptoms in people with dementia. Participants will take two tablets of either pimavanserin or a placebo every day for eight weeks. Researchers will measure any changes in psychological symptoms and monitor participants for any side effects.
