ClinConnect Summary
This clinical trial is studying a new treatment called BMS-986446, which is an antibody designed to target a specific protein linked to Alzheimer's disease. The aim is to find out if this treatment is effective, safe, and easy for people with early signs of Alzheimer’s to tolerate. The trial is currently looking for participants who show early symptoms of Alzheimer’s, such as mild cognitive impairment or mild dementia, and who meet specific criteria regarding their memory and cognitive abilities.
To be eligible for this study, participants need to be between 18 and 90 years old and have a diagnosis of mild cognitive impairment or mild Alzheimer’s disease. They should also have evidence of Alzheimer’s-related changes in their brain and specific scores on memory tests. Throughout the trial, participants can expect to undergo various assessments, including memory tests and imaging scans, to monitor their condition and how well the treatment works. It’s important for interested individuals to discuss any existing health conditions with their doctor, as certain medical issues may prevent them from participating in the study.
