Study Summary

Researchers want to learn if giving MK-1167 (the study medicine) along with acetylcholinesterase inhibitor (AChEI) therapy can improve symptoms of Alzheimer's disease dementia (AD dementia), such as memory and mental activity. AD dementia is the most common type of dementia. AChEI therapy is the standard treatment for AD dementia. The goals of this study are to learn: * If at least one dose level (amount) of MK-1167 works to improve a person's memory and thinking compared to a placebo * About the safety of MK-1167 and if people tolerate it

Primary Outcome

The change from baseline in ADAS-Cog11 score at Week 24 is presented. ADAS-Cog11 is a structured scale that evaluates memory, orientation, attention, reasoning, language, and constructional praxis. ADAS-Cog11 measures cognition by assessing 11 metrics impaired in AD: word recall; commands; constructional praxis; naming objects and fingers; ideational praxis; orientation; word recognition; remembering test instructions; spoken language ability; word-finding difficulty; and comprehension of spoken
