• Overactive mTOR Plays a Key Role in Aging and Alzheimer’s Disease.
  
• Simufilam Suppresses Overactive mTOR, Suggesting a Beneficial Drug Effect.
• Research is Published in Frontiers in Aging, a Peer-reviewed Journal.

AUSTIN, Texas, June 27, 2023 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company, today announced the publication of a new paper in Frontiers in Aging, a peer-reviewed journal focused on age-related scientific research. The new paper examined the effects of simufilam on mTOR. Simufilam is Cassava Sciences’ novel, oral drug candidate currently in Phase 3 clinical testing in patients with mild-to-moderate Alzheimer's disease dementia.

“Today’s publication suggests a meaningful impact of simufilam on overactive mTOR signaling,” said Lindsay Burns, PhD, SVP Neuroscience at Cassava Sciences, and co-author of the paper. “The data add to our understanding of simufilam’s mechanism of action in Alzheimer's disease.”

The scientific literature shows overactive mTOR plays a key role in aging, Alzheimer’s disease and other conditions. When functioning normally, mTOR monitors cellular needs and is activated by insulin. The research published today shows mTOR is overactive in lymphocytes isolated from blood collected from Alzheimer's patients versus healthy controls. After oral administration of simufilam 100 mg twice daily to Alzheimer's patients for 28 days, lymphocytes showed normalized mTOR activity and restored mTOR sensitivity to insulin.

“Normalizing mTOR may have tantalizing potential in Alzheimer’s disease and beyond,” said Remi Barbier, President & CEO. “There is a wide body of research on this topic.”

An abstract of the research paper appeared on-line June 23, 2023, ahead of print and is titled “Simufilam Suppresses Overactive mTOR and Restores Its Sensitivity to Insulin in Alzheimer’s Disease Patient Lymphocytes”.

About Simufilam

Simufilam is Cassava Sciences’ novel, oral drug candidate currently in Phase 3 clinical trials in patients with mild-to-moderate Alzheimer's disease dementia. Simufilam binds tightly to and reverses an altered conformation of the filamin A protein (FLNA) in Alzheimer’s patients. Altered FLNA is critical to the toxicity of amyloid beta (1-42). Simufilam is wholly owned by Cassava Sciences, without royalty or payment obligation to any third party.
