Cassava Updates on Phase 3 Clinical Program

 Overview of On-going Phase 3 Clinical Program

Our Phase 3 program consists of two double-blind, randomized, placebo-controlled studies of simufilam in patients with mild-to-moderate Alzheimer’s disease. Both Phase 3 studies have Special Protocol Assessments (SPA) from the U.S. Food and Drug Administration.

A total of over 120 subjects have now been enrolled in our Phase 3 studies. Studies are being conducted in over 115 clinical trial sites across the U.S., Canada and Puerto Rico.

Overview of Each On-going Phase 3 Study - RETHINK-ALZ and REFOCUS-ALZ
Our Phase 3 study called “RETHINK-ALZ” 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.

Details of the RETHINK-ALZ Phase 3 study include:

• Subjects are randomized (1:1) to simufilam 100 mg or placebo twice daily.

• The co-primary efficacy endpoints are ADAS-Cog12 (a cognitive scale) and ADCS-ADL (a functional scale). A secondary efficacy endpoint is iADRS, a clinical tool that combines cognitive and functional scores from ADAS-Cog & ADCS-ADL.

Our Phase 3 study called “REFOCUS-ALZ” 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.

Details of the REFOCUS-ALZ Phase 3 study, include:

• Subjects are randomized (1:1:1) to simufilam 100 mg, 50 mg, or placebo twice daily.

• The co-primary efficacy endpoints are ADAS-Cog12 (a cognitive scale) and ADCS-ADL (a functional scale). A secondary efficacy endpoint is iADRS, a clinical tool that combines cognitive and functional scores from ADAS-Cog & ADCS-ADL.
