ClinConnect Summary

This clinical trial is studying a new treatment called ML-007C-MA for people with Alzheimer's Disease who experience psychosis, which includes symptoms like hallucinations (seeing or hearing things that aren't there) and delusions (strongly held false beliefs). The trial aims to see if this treatment is effective and safe compared to a placebo, which is a treatment that does not contain any active medication. It is open to men and women aged 55 to 90 who have been diagnosed with Alzheimer's Disease and have had these psychotic symptoms for at least two months.

To participate, individuals need to provide informed consent, either by themselves or through a caregiver if they cannot. They must also have a designated care partner who can help monitor their symptoms. Key eligibility criteria include having a certain level of psychotic symptoms and being stable in a living situation for at least six weeks. Participants will be carefully evaluated throughout the study to track how they respond to the treatment. It's important to note that certain health conditions or recent treatments may exclude someone from participating. This trial is currently not recruiting participants, but it represents an important step in finding new ways to help manage challenging symptoms of Alzheimer's Disease.
