Cassava Sciences Reports Full-year 2021 Financial Results and Operating Updates

AUSTIN, Texas, Feb. 28, 2022 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, today announced financial results for the year ended December 31, 2021 and provided clinical and business updates.

“In second half 2021, we initiated two separate Phase 3 clinical studies with our lead drug candidate, simufilam, in patients with Alzheimer’s disease,” said Remi Barbier, President & CEO. “This was a large, complex endeavor. We deeply appreciate every member of the team inside and outside the Company who contributed to this effort. Our challenge for 2022 and beyond is to enroll over 1,700 patients into our Phase 3 clinical program. With this evolution, we intend to prove once again that we are a small company capable of doing big things.”

Cassava Sciences’ Phase 3 studies are now recruiting patients with mild to moderate Alzheimer’s disease. Drug has been shipped to nearly 100 clinical trial sites across North America, with additional sites planned in the U.S. and overseas. Over 200 patients have been screened to date.

“We are encouraged by our clinical investigators’ high level of enthusiasm,” said Jim Kupiec, MD, Chief Clinical Development Officer. “Looking ahead, we see continued collaboration with the clinical community to ensure qualifying patients with Alzheimer’s disease are successfully enrolled into our Phase 3 studies.”

“Our balance sheet has $233.4 million of cash, against expected cash use of $25 to $35 million in first half 2022, depending on patient enrollment rates and the timing of certain legal expenses,” said Eric Schoen, Chief Financial Officer. “Higher cash use may indicate faster enrollment rates.”

Net loss for full year 2021 was $32.4 million, or $0.82 per share, compared to a net loss of $6.3 million, or $0.24 per share, in 2020. Net cash used in operations full-year 2021 was $30.2 million, consistent with previous guidance. An additional $22.2 million was used primarily for an all-cash purchase of office property in Austin, Texas, which is expected to serve as Cassava Sciences’ corporate headquarters in 2022 and beyond.

Financial Highlights

Overview of Phase 3 Clinical Program - RETHINK-ALZ and REFOCUS-ALZ
The Phase 3 program consists of two double-blind, randomized, placebo-controlled studies of simufilam in patients with mild-to-moderate Alzheimer’s disease. Both Phase 3 studies have Special Protocol Assessments (SPA) from FDA. Both Phase 3 studies were initiated in Fall 2021.

The RETHINK-ALZ Phase 3 study is designed to evaluate the safety and efficacy of oral simufilam 100 mg in enhancing cognition and slowing functional decline over 52 weeks. Secondary objectives include the assessment of simufilam's effect on neuropsychiatric symptoms and caregiver burden. This randomized, double-blind, placebo-controlled study plans to enroll approximately 750 patients with mild-to-moderate Alzheimer’s disease in the U.S. and Canada and, eventually, overseas.

Details of the RETHINK-ALZ Phase 3 study include:

The REFOCUS-ALZ Phase 3 study is designed to evaluate the safety and efficacy of oral simufilam 100 mg and 50 mg over 76 weeks. This randomized, double-blind, placebo-controlled study plans to enroll approximately 1,000 patients with mild-to-moderate Alzheimer’s disease in the U.S. and Canada and, eventually, overseas.

Details of the REFOCUS-ALZ Phase 3 study, include:

Open-label Study

In March 2020, we initiated a long-term, open-label study to evaluate simufilam, our lead drug candidate, in patients with mild-to-moderate Alzheimer’s disease. The study is intended to monitor the long-term safety and tolerability of simufilam 100 mg twice daily for 12 or more months. Another study objective is to measure changes in cognition and biomarkers.

In September 2021, the open-label study reached its final target enrollment of approximately 200 subjects with Alzheimer’s disease. We expect to announce full study results second half 2022.

The study protocol has pre-specified interim analyses, including cognition measurements at 6, 9 and 12 months. ADAS-Cog scores improved 1.6 points, 3.0 points and 3.2 points from baseline in the first 50 study participants who completed, respectively, 6, 9 and 12 months of open-label treatment with simufilam. It is understood that cognition data from an open-label study has limitations compared to efficacy data from a fully completed, large, randomized controlled trial.

In 2022, we may conduct one or more ad hoc interim analyses on measurements of cognition on the open-label study.

Another objective of this study is to measure changes in levels of biomarkers in patients treated with open label simufilam. In July 2021, we announced positive biomarker data at 6 months. Biomarker data were analyzed from cerebrospinal fluid (CSF) collected from 25 study participants who agreed to undergo a lumbar puncture at baseline and again after 6 months of treatment. In this cohort of 25 study participants, simufilam robustly improved CSF biomarkers of disease pathology (t-tau and p-tau181 decreased 38% and 18%, respectively); CSF biomarkers of neurodegeneration (neurogranin and NfL, decreased 72% and 55%, respectively); and CSF biomarkers of neuroinflammation (sTREM2 and YKL-40, decreased 65% and 44%, respectively).

In 2022, we expect to measure changes in levels of biomarkers in patients treated with open label simufilam for 12 months.

Cognition Maintenance Study (CMS)
In May 2021, we initiated a Cognition Maintenance Study (CMS). This is a double-blind, randomized, placebo-controlled study of simufilam in patients with mild-to-moderate Alzheimer’s disease. Study participants are randomized (1:1) to simufilam or placebo for six months. To enroll in the CMS, patients must have previously completed 12 months or more of open-label treatment with simufilam. The CMS is designed to evaluate simufilam’s effects on cognition and health outcomes in Alzheimer’s patients who continue with drug treatment versus patients who discontinue drug treatment. The target enrollment for the CMS is approximately 100 subjects. Over 60 subjects have been enrolled in the CMS and 30 have completed the study.

Our investigational diagnostic product candidate, called SavaDx, is an early-stage program focused on detecting the presence of Alzheimer’s disease from a small sample of blood. For business, technical and personnel reasons, we continue to prioritize the development of simufilam, our lead drug candidate, over SavaDx. The regulatory pathway for SavaDx may eventually include formal analytical validation studies and clinical studies that support evidence of sensitivity, specificity and other variables in various healthy and diseased patient populations. We have not conducted such studies and do not expect to conduct such studies in 2022.

SavaDx is currently designed as an antibody-based detection system for altered filamin A (FLNA). In 2022, we plan to evaluate a new approach to detect FLNA without the use of antibodies.

About Simufilam
Simufilam (sim-uh-FILL-am) is a proprietary, small molecule (oral) drug that restores the normal shape and function of altered filamin A (FLNA) 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 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 Cassava Sciences, Inc.
Cassava Sciences’ mission is to discover and develop innovations for chronic, neurodegenerative conditions. Over the past 10 years, Cassava Sciences has combined state-of-the-art technology with new insights in neurobiology to develop novel solutions for Alzheimer’s disease. We are currently testing simufilam, our lead drug candidate for the proposed treatment of Alzheimer’s disease, in Phase 3 clinical studies under Special Protocol Assessments from the FDA. Simufilam is also being tested in an open-label study and a randomized, double-blind, placebo-controlled Cognition Maintenance Study in patients with Alzheimer’s disease.
