Cassava Sciences Announces Initiation of an Open-Label Study to Evaluate PTI-125 in Patients with Alzheimer’s DiseaseApproximately 100 Study Participants Will Receive PTI-125 For 12 Months

AUSTIN, Texas, March 25, 2020 (GLOBE NEWSWIRE) -- Cassava Sciences Inc., Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, today announced the initiation of an open-label extension study to evaluate PTI-125 in patients with Alzheimer’s disease. The Company’s lead investigational drug, PTI-125, seeks to improve both neurodegeneration and neuroinflammation in patients with Alzheimer’s disease.

“We believe the ability of our drug to improve multiple functions in the brain represents a new, different and crucial approach to treat Alzheimer’s disease,” said Remi Barbier, President & CEO. “This study will provide an opportunity for patients from prior studies of PTI-125 to participate in additional clinical research and to increase our knowledge of our drug’s long-term safety profile.”

Initiation of the open-label study follows the earlier announcement and publication of positive results in a Phase 2a study of PTI-125 in patients with Alzheimer’s disease. A Phase 2b study remains on-going, with top-line results still expected approximately mid-year 2020.

Open-label Study Design
This open-label, multi-center, extension study will monitor the long-term safety and tolerability of PTI-125 at 100 mg twice-daily for 12 months. The study’s target enrollment is approximately 100 patients with mild-to-moderate Alzheimer’s disease, including patients from prior studies of PTI-125. Study sites may initially slow the pace of patient enrollment to minimize any risks of exposing elderly patients to infectious disease during office visits.

About PTI-125
Cassava Sciences’ lead therapeutic product candidate is for the treatment of Alzheimer’s disease. PTI-125 is a proprietary, small molecule (oral) drug that restores the normal shape and function of altered filamin A (FLNA), a scaffolding protein, in the brain. Altered FLNA in the brain disrupts the normal function of neurons, leading to Alzheimer’s pathology, neurodegeneration and neuroinflammation. PTI-125 seeks to simultaneously improve both neurodegeneration and neuroinflammation. The underlying science is published in peer-reviewed scientific journals, including Journal of Neuroscience, Neurobiology of Aging, Journal of Biological Chemistry and Journal of Prevention of Alzheimer’s Disease. The Company is also developing an investigational diagnostic, called SavaDx, to detect Alzheimer’s disease with a simple blood test.

About Alzheimer's Disease
Alzheimer’s disease is a progressive brain disorder that destroys memory and thinking skills. Currently, there are no drug therapies to halt Alzheimer’s disease, much less reverse its course. In the U.S. alone, approximately 5.8 million people are currently living with Alzheimer’s disease, and approximately 487,000 people age 65 or older developed Alzheimer’s in 2019.1 The number of people living with Alzheimer’s disease is expected to grow dramatically in the years ahead, resulting in a growing social and economic burden.2
