Cassava Sciences Announces Completion of Dosing in Open-label Study of Simufilam for Alzheimer’s Disease

Cassava Sciences, Inc.
Cassava Sciences, Inc.
  • Outside Biostatisticians with Specific Expertise in Alzheimer’s Disease Will Conduct an Independent Statistical Analysis on The Clinical Dataset.

  • Clinical Dataset May Be Announced Approximately Year-End 2022, Pending Completion of Study Report by Outside Biostatisticians.

AUSTIN, Texas, Dec. 06, 2022 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company, today announced the completion of drug administration in an open-label study of simufilam for Alzheimer’s disease. This study was designed to evaluate long-term drug safety and to measure cognitive changes (ADAS-cog) over 12 months in approximately 200 patients with mild-to-moderate Alzheimer’s disease treated with open-label simufilam 100 mg twice daily. Simufilam is Cassava Sciences’ oral drug candidate for Alzheimer’s disease dementia.

To ensure the highest integrity of data analysis, outside biostatisticians with specific expertise in Alzheimer’s disease will conduct an independent statistical analysis on the clinical dataset. Cassava Sciences may announce study results approximately year-end 2022, pending completion of a study report by outside biostatisticians.

“We are thrilled with the progress made to date in the clinical development of simufilam, our oral drug candidate for people with Alzheimer’s disease,” said Remi Barbier, President & CEO. “We applaud recent clinical advances with anti-amyloid antibody drugs for Alzheimer’s, but these may not be enough. I think innovations are needed around new targets, new molecules, drug safety and dosing. I believe Cassava Sciences may be at the forefront of this effort to innovate.”

Overview of On-going Phase 3 Clinical Program
Cassava Sciences is evaluating simufilam for Alzheimer’s disease dementia in two Phase 3 clinical studies. Both studies have received a Special Protocol Assessment (SPA) from the U.S. Food and Drug Administration. Over 750 patients are now enrolled in the Phase 3 program.

Cassava Sciences’ RETHINK-ALZ Phase 3 study is designed to evaluate the safety and efficacy of oral simufilam 100 mg in enhancing cognition and slowing functional decline over 52 weeks. This randomized, double-blind, placebo-controlled study plans to enroll approximately 750 patients with mild-to-moderate Alzheimer’s disease. Patients are randomized (1:1) to simufilam 100 mg or matching placebo twice daily.

Cassava Sciences’ REFOCUS-ALZ Phase 3 study is designed to evaluate the safety and efficacy of oral simufilam 100 mg and 50 mg over 76 weeks. This randomized, double-blind, placebo-controlled study plans to enroll approximately 1,000 patients with mild-to-moderate Alzheimer’s disease. Patients are randomized (1:1:1) to simufilam 100 mg, 50 mg, or placebo twice daily.

Both Phase 3 studies have the same co-primary efficacy endpoints: ADAS-Cog12 (a cognitive scale) and ADCS-ADL (a functional scale).
