Certainly! Let’s compare the test results for Aducanumab and Simufilam in the context of Alzheimer’s disease:
Aducanumab:
Aducanumab (marketed as Aduhelm) is an antibody-based treatment that targets amyloid-beta plaques in the brain, which are associated with Alzheimer’s disease.
In a Phase 3 clinical trial, Aducanumab demonstrated a reduction in amyloid plaques and a potential impact on cognitive decline1.
However, its approval has been controversial due to mixed results and concerns about safety and efficacy.
Simufilam:
Simufilam is an experimental oral therapy developed by Cassava Sciences. It aims to improve cognition in people with Alzheimer’s disease.
Two Phase 3 clinical trials are currently evaluating Simufilam:
RETHINK-ALZ (NCT04994483): Testing Simufilam (100 mg twice daily) against a placebo for a year in people with mild to moderate Alzheimer’s. Results are expected by the end of this year.
REFOCUS-ALZ (NCT05026177): Testing two doses of Simufilam (50 or 100 mg twice daily) against a placebo for 76 weeks. Results are due in 2025.
Interim safety reviews have not raised significant issues, and MRI data from REFOCUS-ALZ showed no cases of ARIA-E (amyloid-related imaging abnormalities edema) after 40 weeks2.
Notably, two-thirds of participants in a study funded by the National Institutes of Health improved their cognition scores after nine months on Simufilam3.
In summary, while Aducanumab has faced controversy, Simufilam shows promise in slowing cognitive decline and improving cognition in Alzheimer’s patients. We await further results from ongoing trials to better understand their effectiveness and safety profiles.
