Cassava Sciences Reports Q1 2024 Financial Results and Clinical Updates on Phase 3 Trials of Simufilam

• $126.3 Million In Total Gross Proceeds from Warrant Distribution.
  
  
• Over 1,900 Patients with Alzheimer’s Disease Are Randomized in Phase 3 Trials of Simufilam.
  
  
• Over 735 Patients Have Completed a Phase 3 Trial of Simufilam.

AUSTIN, Texas, May 10, 2024 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a biotechnology company focused on Alzheimer’s disease, today reported financial results for first quarter ended March 31, 2024. Net income was $25.0 million compared to a net loss of $24.3 million for the same period in 2023. Net cash used in operations was $19.1 million during the first quarter of 2024. Cash use for operations for the first half of 2024 is still expected to be $35 to $45 million, driven primarily by expenses for our clinical program in Alzheimer’s disease.

Current Updates on Phase 3 Clinical Program
Background - Our Phase 3 program consists of two global, double-blind, randomized, placebo-controlled studies of simufilam in patients with mild-to-moderate Alzheimer’s disease dementia. The goal is to evaluate overall risk/benefit for simufilam 100 mg 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 (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, called RETHINK-ALZ, is designed to evaluate the safety and efficacy of simufilam 100 mg tablets twice-daily versus matching placebo over 52 weeks (NCT04994483). Our second Phase 3 study, called REFOCUS-ALZ, is designed to evaluate the safety and efficacy of oral simufilam 100 mg and 50 mg tablets twice-daily versus matching placebo over 76 weeks (NCT05026177). Clinical sites are in the United States, Canada, Puerto Rico, Australia, and South Korea. Premier Research International is the clinical research organization (CRO) supporting the conduct of our Phase 3 clinical program. 

Patient Enrollment – Both Phase 3 studies are fully enrolled. Approximately 1,900 patients are randomized in these studies, with approximately 800 patients randomized  in the 52-week study (RETHINK-ALZ) and approximately 1,100 patients randomized  in the 76-week study (REFOCUS-ALZ). Approximately 90% of patients are recruited from clinical sites in the U.S. and Canada. The overall drop-out rate for both Phase 3 studies is in the range of 20% to 22%, which is generally consistent with expectations. (A longer study will generally have a higher dropout rate versus a similar shorter study).

Patient Completion – Over 435 patients have completed the 52-week RETHINK-ALZ study. Over 300 patients have completed the 76-week REFOCUS-ALZ study, for a total of over 735 completers.

Data Safety and Monitoring Board (DSMB) – The DSMB is composed of independent clinical research experts who periodically review interim patient safety data. Routine, scheduled DSMB meetings were held September 2023 and March 2024. Both DSMB meetings recommended that the Phase 3 studies continue as planned, without modification.

Co-primary Efficacy Outcomes – The pre-specified efficacy endpoints are ADAS-Cog12, a cognitive scale, and ADCS-ADL, a functional scale. iADRS is a combination of scores from ADAS-Cog and ADCS-ADL. Because the distribution of study participants is numerically skewed towards mild patients, we expect to rely predominantly on mild patients to evaluate drug safety and efficacy.

Phase 3 Efficacy Results – All efficacy data from our Phase 3 program remain blinded. No interim analyses on efficacy outcomes are planned. We anticipate top-line data readout for our 52-week study (RETHINK-ALZ) approximately year-end 2024. We anticipate top-line data readout for our 76-week study (REFOCUS-ALZ) approximately mid-year 2025.

Open-label Extension Study – This study is designed to provide no-cost access to oral simufilam for up to one year to Alzheimer’s patients who have successfully completed a Phase 3 study of simufilam and who meet other entry criteria. Approximately 90% of patients who’ve completed treatment in a Phase 3 study have opted to enter the open-label extension study. To date, over 655 patients have entered the open-label extension study.

Financial Results for First Quarter 2024

• At March 31, 2024, cash and cash equivalents were $124.2 million, with no debt.
• The total gross proceeds received from the cash-exercise of Warrants were $126.3 million, including approximately $104.0 million received in April and May 2024.
• Net income was $25.0 million compared to a net loss of $24.3 million for the same period in 2023. Net income resulted from the change in fair value of warrant liabilities, a non-cash item. This warrant gain was partially offset by increases in patient enrollment and associated costs to conduct the Phase 3 clinical program, as well as other studies with simufilam.
• Net cash used in operations was $19.1 million during the first quarter of 2024.
• Net cash use in operations for first half 2024 is expected to be $35 to $45 million, consistent with previous guidance and driven primarily by expenses for our program in Alzheimer’s disease.
• Research and development (R&D) expenses were $16.2 million. This compared to $22.1 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.
• General and administrative (G&A) expenses were $3.7 million. This compared to $4.4 million for the same period in 2023. G&A expenses decreased due primarily to higher legal expenses being offset by approximately $3.0 million in insurance recoveries during the three months ended March 31, 2024. Insurance recoveries are recorded as a reduction to G&A expense. The decrease was partially offset by a $1.1 million increase in stock-based compensation expense due to new grant awards in 2023.
• In January 2024, we completed a dividend distribution of common stock warrants to shareholders (“Warrants”). The Warrants allowed the holder to purchase shares of our common stock for an effective price of $22.00 per share. The deadline to cash-exercise Warrants was May 6th, 5pm New York City time. There is no further opportunity to exercise Warrants. Warrants outstanding that were not validly exercised were being redeemed by the Company starting on or around May 7, 2024, for a nominal payment of $0.001 per Warrant.
