AUSTIN, Texas, Oct. 13, 2022 (GLOBE NEWSWIRE) — Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, today announced the initiation of an open-label extension study. This study is designed to provide no-cost access to simufilam, an investigational drug, to patients with Alzheimer’s disease who complete either one of Cassava Sciences’ on-going Phase 3 studies, which are double-blind, placebo-controlled trials.

“We believe this open-label study is the right thing to do,” said Remi Barbier, President & CEO. “Alzheimer’s patients who complete one of our Phase 3 studies are eligible to enroll, knowing there is no placebo and no blinding in our open-label extension study.”

Open-label Extension Study Design
This multi-center, multi-national, open-label extension study is expected to generate long-term safety and tolerability data for (oral) simufilam 100 mg twice daily over 52 weeks. Each clinical investigational site must choose whether to participate in this open-label extension study. Patient enrollment for this study is expected to begin early November 2022.
