ClinConnect Summary
This clinical trial is studying a new medication called ACP-204 for adults with Alzheimer's Disease Psychosis (ADP), which involves experiencing confusion or delusions related to Alzheimer's disease. The trial will be conducted at multiple locations and includes three parts. The first part will test two different doses of ACP-204 (30 mg and 60 mg) to see how effective they are compared to a placebo (a pill with no active medication). If the first part shows promising results, the next two parts will further confirm the effectiveness of the doses.
To be eligible for the trial, participants need to be between 55 and 95 years old and must have a diagnosis of Alzheimer's disease with psychotic symptoms lasting at least two months. They also need to have a reliable caregiver to assist them throughout the study. Participants will go through a screening period, followed by six weeks of treatment, and then a safety follow-up to monitor their health. The trial is currently recruiting participants, and those interested should reach out to learn more about joining the study.
