AUSTIN, Texas, Nov. 07, 2024 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on developing a novel treatment for Alzheimer’s disease, today reported financial results for the third quarter ended September 30, 2024.

“We look forward to the release of top-line results from RETHINK-ALZ, our first Phase 3 trial for simulfilam, by the end of 2024,” said Rick Barry, President and Chief Executive Officer. “This will represent the culmination of three-plus years of concerted effort by our clinical team, principal investigators, patients and their caregivers.”

Current Updates on Phase 3 Clinical Program
Background - Our Phase 3 program consists of two global, double-blind, randomized, placebo-controlled studies of simufilam, an investigational agent in development for the potential treatment of patients with mild-to-moderate Alzheimer’s disease (“Alzheimer’s” or “AD”). The program’s goal is to evaluate the overall safety and efficacy of oral simufilam, administered twice-daily, versus placebo, in a large population of people with Alzheimer’s disease over 12 and 18 months.

The target study population is people with mild-to-moderate Alzheimer’s (mini-mental state examination, (MMSE) score of 16-27) who are biomarker-positive for Alzheimer’s disease pathology and who meet other inclusion/exclusion eligibility criteria of the study protocols.

Phase 3 Trials – Our first Phase 3 study, RETHINK-ALZ (NCT04994483), is designed to evaluate the safety and efficacy of simufilam 100 mg tablets administered twice-daily versus matching placebo over 52 weeks. Our second Phase 3 study, REFOCUS-ALZ (NCT05026177), is designed to evaluate the safety and efficacy of two doses of oral simufilam tablets, 100 mg and 50 mg, administered twice-daily, versus matching placebo, over 76 weeks. Clinical sites are in the United States, Canada, Puerto Rico, Australia, and South Korea.

Patient Enrollment – Both Phase 3 studies are fully enrolled. Approximately 1,900 patients are randomized in these studies, with approximately 800 patients randomized into RETHINK-ALZ and approximately 1,100 patients randomized into REFOCUS-ALZ. Approximately 90% of patients are recruited from clinical sites in the U.S. and Canada. The overall drop-out rate was 21% for RETHINK-ALZ and has been 25% for REFOCUS-ALZ; these numbers are generally consistent with expectations.

Patient Completion – The Last Patient/Last Visit (LPLV) occurred several weeks ago for the RETHINK-ALZ study, with approximately 635 patients completed. To date, over 550 patients have completed the REFOCUS-ALZ study, for a total of over 1,185 completers.

Data and Safety Monitoring Board (DSMB) – The DSMB is composed of independent clinical research experts who periodically review interim patient safety data. Following a third routine, scheduled meeting in September 2024, the DSMB recommended that both of our Phase 3 studies continue as planned, without modification. This was consistent with recommendations of the DSMB following meetings in September 2023 and March 2024.

Co-primary Efficacy Outcomes – The pre-specified efficacy endpoints for the Phase 3 studies are Alzheimer’s Disease Assessment Scale-Cognitive subscale 12 (ADAS-Cog12), a cognitive scale, and Alzheimer’s Disease Cooperative Study – Activities of Daily Living subscale, (ADCS-ADL), a functional scale.

Phase 3 Efficacy Results – All efficacy data from our Phase 3 program remain blinded. No interim analyses on efficacy outcomes are planned. We expect to report top-line data for RETHINK-ALZ before the end of 2024. We anticipate a top-line data readout for REFOCUS-ALZ approximately mid-year 2025.

Open-label Extension Study – This study is designed to provide no-cost access to oral simufilam to Alzheimer’s patients who have successfully completed a Phase 3 study of simufilam and who meet other entry criteria. Approximately 88% of patients who have completed treatment in one of the two Phase 3 studies, RETHINK-ALZ or REFOCUS-ALZ, have opted to enter the open-label extension (OLE) study. To date, over 1,040 patients have entered the OLE study. The OLE study is intended to continue for up to 36 months or until a new drug application for simufilam has been reviewed by FDA. Cassava also plans to add cognition and plasma biomarker monitoring to its OLE trial for patients who have completed either of the two Phase 3 trials, in order to gather additional long-term data on the potential impact of simufilam treatment.

Financial Results for Third Quarter 2024

• At September 30, 2024, cash and cash equivalents were $149.0 million. The Company has no debt.
• Net loss was $27.9 million or $0.58 per share. This compares to a net loss of $25.7 million, or $0.61 per share, for the same period in 2023.
• Net cash used in operations was $55.7 million during the first nine months of 2024.
• Net cash used in operations for second half 2024 is expected to be $40 to $50 million, consistent with previous guidance. In addition, the Company intends to pay a previously announced $40 million SEC investigation settlement, which has been placed in escrow and excluded from cash and cash equivalents. The Company estimates cash and cash equivalents at year-end 2024 in a range from $117 to $127 million.
• Research and development (R&D) expenses were $17.7 million. This compared to $23.6 million for the same period in 2023. R&D expenses decreased due primarily to the completion of patient screening and enrollment for our Phase 3 clinical program in the fall of 2023. Patients are continually completing the Phase 3 program and a portion of completers are enrolling in the lower cost open-label extension study. These decreases were partially offset by an increase in stock-based compensation expense due to new grant awards in the third quarter of 2024.
• General and administrative (G&A) expenses were $12.9 million. This compared to $4.3 million for the same period in 2023. G&A expenses increased significantly due primarily to higher legal related expenses, increased compensation costs, including severance, as well as an increase in stock-based compensation expense due to new grant awards in late 2023 and 2024.

About Cassava Sciences, Inc.
Cassava Sciences is a clinical-stage biotechnology company based in Austin, Texas. Our mission is to detect and treat neurodegenerative diseases, such as Alzheimer’s disease.

Simufilam is an investigational oral, small molecule drug candidate currently being evaluated in two Phase 3 clinical trials for the potential treatment of Alzheimer's disease. Simufilam targets a specific site on filamin A, a scaffolding protein that is critical to certain receptor interactions in the brain. Cassava Sciences believes that simufilam interrupts amyloid-β42 binding to receptors in the brain and may affect the Alzheimer's disease process. Cassava Sciences owns exclusive, worldwide rights to its investigational product candidates and related technologies, without royalty obligations to any third party.
