High Dose Simufilam for Mild-to-Moderate Alzheimer's Disease (RETHINK-ALZ)

Start: November 3, 2021
End: October 2023
Enrollment: 750

What Is This Study About?

This Phase 3 clinical trial, named RETHINK-ALZ, will test the safety and effects of the experimental drug simufilam (100 mg) designed to slow cognitive and functional decline in older adults with mild-to-moderate Alzheimer's disease. All participants will be randomly assigned to receive either 100 mg tablets of simufilam or a placebo, twice daily, for one year. After the initial clinical exam at the start of the study, participants will receive a clinical evaluation after four weeks and then every three months until the end of the study. Testing will include neurological exams, laboratory tests, electrocardiograms, questionnaires, and interviews. Some study locations may also analyze blood samples or cerebral spinal fluid (optional) to measure the levels of proteins associated with Alzheimer's disease. Researchers will monitor all participants for safety throughout the study and measure changes in cognitive function and mobility.
