Trial Summary

What is the purpose of this trial?This trial tests simufilam, a pill taken twice daily, on people with mild-to-moderate Alzheimer's disease. The goal is to see if it can improve memory and slow down the worsening of symptoms by helping the brain work better and reducing harmful swelling. The study will last for about a year and involve periodic check-ups to monitor safety and effectiveness.

This trial is for adults with mild-to-moderate Alzheimer's Disease who have been stable on current AD medications for at least 12 weeks, have a certain range of cognitive function scores, and haven't smoked in 3+ years. They need a study partner and can't join if they've had recent seizures or strokes, uncontrolled diabetes or hypertension, severe psychiatric conditions, specific BMI limits, or are taking certain other AD drugs.
