Summary
This trial is testing a new drug, MK-1942, together with an existing Alzheimer's medication, donepezil. It focuses on patients with mild-to-moderate Alzheimer's who are already taking donepezil. The study aims to see if this combination is safe and if it causes any new or more severe side effects. Researchers will also check how the body processes both drugs when taken together. Donepezil is a well-established treatment for Alzheimer's disease, used to improve cognition and global function in patients with mild to severe stages of the disease.
