• Cash and cash equivalents were $282.2 million at March 31, 2021 

Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, today announced financial results for the first quarter ended March 31, 2021 and guidance regarding the release of new clinical data with simufilam. Simufilam is the Company’s lead drug candidate to treat Alzheimer’s disease.

“Alzheimer’s is a progressive disease, so a patient’s cognition is expected to worsen over time,” said Remi Barbier, President & CEO. “Patients’ cognition scores actually improved following 6 months of open-label treatment with simufilam. Showing similar drug effects following 9 months of open-label treatment would be remarkable, yet consistent with simufilam’s mechanism of action. Eventually, we’d like this drug candidate to benefit cognition for a year or longer.”

In July 2021, Cassava Sciences plans to announce results of a pre-specified interim analysis that summarizes safety and cognition data on approximately the first 50 subjects to complete at least 9 months of open-label drug treatment. The Company will present these data July 26 - 29^th at the 2021 Alzheimer’s Association International Conference (AAIC). AAIC’s scientific committee has invited the Company’s scientists to present the dataset as an oral presentation.

About the Open-label Study with Simufilam

In March 2020, Cassava Sciences initiated a long-term, open-label study to evaluate simufilam in patients with Alzheimer’s disease. This study is funded by a research grant award from the National Institutes of Health (NIH). The open-label study is intended to monitor the long-term safety and tolerability of simufilam 100 mg twice-daily for 12 months or longer in patients with Alzheimer’s disease. Another study objective is to measure changes in cognition on ADAS-Cog, a standard test of cognition in Alzheimer’s disease. The study’s clinical protocol has pre-specified cognition measurements at 6, 9 and 12 months.

The study’s target enrollment is approximately 150 subjects with mild-to-moderate Alzheimer’s disease (recently increased by 50 subjects). One-hundred subjects have enrolled in this study across multiple clinical sites in the U.S. and Canada.

On February 2, 2021, Cassava Sciences announced positive results of a first interim analysis that summarizes clinical data on the first 50 subjects to complete 6 months of open-label treatment. Patients’ cognition scores improved from baseline following 6 months of simufilam treatment, with no safety issues. Six months of simufilam treatment improved cognition scores by 1.6 points on ADAS-Cog11, a 10% mean improvement from baseline to month 6.

In September 2021, Cassava Sciences plans to announce results of an interim analysis that summarizes safety and cognition data on approximately the first 50 subjects to complete at least 12 months of open-label drug treatment.

About the Cognition Maintenance Study (CMS)

In June 2021, Cassava Sciences plans to initiate a double-blind, randomized, placebo-controlled study in patients with Alzheimer’s disease. Patients who have completed at least one year of open-label treatment with simufilam qualify to enroll in the Cognition Maintenance Study (CMS). Study subjects in the CMS will be randomized (1:1) to simufilam or placebo for six months. The CMS is designed to compare simufilam’s effects on cognition in Alzheimer’s patients who continue with drug treatment versus patients who discontinue drug treatment.

About the Phase 3 Clinical Program

Cassava Sciences plans to initiate a Phase 3 program of simufilam in Alzheimer’s disease in the second half of 2021. The Phase 3 program consists of two large, double-blind, randomized, placebo-controlled studies in patients with mild-to-moderate Alzheimer’s disease dementia.

Cassava Sciences’ first Phase 3 study is designed to evaluate disease-modifying effects of simufilam in Alzheimer’s disease. The goal is to demonstrate a slower rate of decline in cognition and health function in subjects treated with simufilam compared to placebo. Approximately 1,000 subjects to be enrolled, randomized (1:1:1) to simufilam 100 mg, 50 mg or placebo BID, and treated for 18 months. The co-primary efficacy endpoints are ADAS-Cog, a cognitive scale, and ADCS-ADL, a functional scale, both widely used clinical tools in trials of Alzheimer’s disease.

Cassava Sciences’ second Phase 3 study is designed to evaluate symptomatic improvement in Alzheimer’s disease. The goal is to demonstrate improved cognition and health function in subjects treated with simufilam compared to placebo. Approximately 600 subjects to be enrolled, randomized (1:1) to simufilam 100 mg or placebo BID, and treated for 12 months. The co-primary efficacy endpoints are ADAS-Cog, a cognitive scale, and ADCS-ADL, a functional scale.

Financial Results for First Quarter 2021

Net loss was $3.5 million, or $0.09 per share, compared to a net loss of $1.2 million, or $0.05 per share, for the same period in 2020. Net cash used in operations was $2.3 million during the first quarter of 2021.

Net cash use for operations for full-year 2021 is expected to be approximately $20 to $25 million. Cash and cash equivalents were $282.2 million as of March 31, 2021, with no debt.

Financial Highlights for First Quarter 2021

• At March 31, 2021, cash and cash equivalents were $282.2 million, compared to $93.5 million at December 31, 2020, with no debt. Cash balance included net proceeds of approximately $189.8 million from the sale of 4.1 million shares of common stock completed February 2021. Cash balance also included $0.7 million from exercise of common stock warrants in the quarter. There were no remaining common stock warrants outstanding as of March 31, 2021.
  
  
• Net cash used in operations during the quarter ended March 31, 2021 was $2.3 million, net of reimbursements received from NIH grant awards.
  
  
• Research grant funding reimbursements of $0.6 million were received from NIH and recorded as a reduction in research and development (R&D) expenses. This compared to $1.3 million of NIH grant receipts received for the same period in 2020.
  
  
• Net cash use for operations for full year 2021 is expected to be approximately $20 to $25 million, consistent with previous financial guidance. Net cash use in 2021 is expected to be driven by higher headcount and personnel expenses, manufacturing costs around large-scale drug supply, professional services expenses related to clinical programs, and operating costs such as insurance, office space and IT related expenses.
  
  
• R&D expenses were $2.5 million. This compared to $0.5 million for the same period in 2020, representing a 365% increase. This increase was due primarily to costs related to manufacture of clinical trial supplies in anticipation of launching a Phase 3 clinical program in simufilam, increased personnel expenses, as well as a decrease in grant funding received from NIH compared to the prior year.
  
  
• General and administrative (G&A) expenses were $1.0 million. This compared to $0.8 million for the same period in 2020, representing a 29% increase. This increase was due primarily to higher insurance costs and professional fees compared to the prior year.

About Simufilam

Simufilam 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. The underlying science for simufilam is published in peer-reviewed journals, including Journal of Neuroscience, Neurobiology of Aging, Journal of Biological Chemistry, Neuroimmunology and Neuroinflammation and Journal of Prevention of Alzheimer’s Disease. Cassava Sciences is also developing an investigational diagnostic, called SavaDx, to detect Alzheimer’s disease with a simple blood test.

Simufilam and SavaDx were both developed in-house. Both product candidates are substantially funded by peer-review research grant awards from the National Institutes of Health (NIH). Cassava Sciences owns worldwide development and commercial rights to its research programs in Alzheimer’s disease, and related technologies, without royalty obligations to any third party.

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. As of 2020, there were approximately 50 million people worldwide living with dementia, a figure expected to increase to 150 million by 2050.¹ The annual global cost of dementia is now above $1 trillion, according to Alzheimer’s Disease International, a charitable organization.
