EU CTIS ID: 2024-513035-25-00
What this study is testing
To evaluate the efficacy of ITI-1284 administered once daily compared with placebo in the treatment of psychosis in patients with Alzheimer’s disease (AD), as measured by change from baseline to end of Week 6 in the Behavioral Pathology in Alzheimer’s Disease Rating Scale (BEHAVE-AD) psychosis subscale score

- The patient is unable or unwilling to discontinue other drugs with known psychotropic properties or any non-psychotropic drugs with known or potentially significant central nervous system effects. See Section 7.7.2 for additional information
