This study is testing a new drug called ACP-204 for people with Lewy Body Dementia Psychosis (LBDP). Lewy Body Dementia is a brain disorder that affects memory and thinking. Psychosis means seeing or hearing things that aren't there. This study is in Phase 2, which means it is testing if the drug works and is safe. It's a double-blind study, so neither the patients nor the researchers know who is getting the real drug or a placebo (a fake pill). This helps make sure the results are fair.

• The study lasts for 6 weeks and involves multiple visits to the study center.
• Participants must be between 55 and 85 years old and meet certain health criteria.
• If you join, you will not know if you are taking ACP-204 or a placebo.
