Cassava Sciences Reports Q1 2023 Financial Results and Operating Updates

• Over 1,244 Alzheimer’s patients now enrolled in Phase 3 studies of simufilam.
• Completion of patient enrollment for Phase 3 program still expected Q4 2023.
• $187.5 Million Cash and Cash Equivalents at March 31, 2023.

AUSTIN, Texas, May 01, 2023 (GLOBE NEWSWIRE) — 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, 2023. Net loss was $24.3 million, or $0.58 per share, compared to a net loss of $17.5 million, or $0.44 per share, for the same period in 2022. Net cash used in operations was $13.3 million during the first quarter of 2023. New guidance for net cash use in first half 2023 is expected to be $30 to $40 million, which is revised downward from our previous guidance of $45 to $50 million, due primarily to the timing of certain clinical payment obligations.

Cassava Sciences is evaluating its lead drug candidate, simufilam, in people with Alzheimer’s disease. Over 1,244 patients with mild-to-moderate Alzheimer’s disease are now enrolled in our Phase 3 program of simufilam, up from over 1,000 enrolled patients as of February 28, 2023. The target enrollment is approximately 1,750 patients.

“In Q1 2023, we announced results of a one-year, open-label Phase 2 safety study of simufilam in over 200 patients with Alzheimer’s disease,” said Remi Barbier, President & CEO. “The dataset for this study shows long-term safety for simufilam. Notably, the data also show differences in changes in ADAS-Cog scores in mild and moderate subgroups. We believe this is an encouraging result, as it clearly shows an improvement in ADAS-Cog over 1 year in mild patients taking simufilam that is well outside the expected range of historical placebo decline from numerous other studies.”

Mr. Barbier continued, “Looking forward, our top priority is to complete patient enrollment for our Phase 3 program. We also look forward to announcing science updates, including completion of patient dosing for our Cognition Maintenance Study. In this randomized, placebo-controlled study, over 100 patients with mild-to-moderate Alzheimer’s who completed at least one year of open-label treatment with simufilam are subsequently randomized to placebo or simufilam for six months. This is known as a randomized, withdrawal study design. While complex, I think this study design may yield interesting clinical data in Q3. Separately, in Q2 we expect to announce new evidential data for the biological activity of simufilam on filamin A protein.”

Financial Results for First Quarter 2023

• At March 31, 2023, cash and cash equivalents were $187.5 million, with no debt.
• Net loss was $24.3 million, or $0.58 per share. This compares to a net loss of $17.5 million, or $0.44 per share, for the same period in 2022. Net loss increased due primarily to increases in the rate of 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 $13.3 million during the first quarter of 2023.
• Net cash use in operations for the first half 2023 is now expected to be $30 to $40 million, compared to previous guidance of $45 to $50 million due primarily to the timing of certain payment obligations for studies of simufilam.
• Research and development (R&D) expenses were $22.1 million. This compared to $14.9 million for the same period in 2022. R&D expenses increased due primarily to increasing patient enrollment and costs to conduct the Phase 3 clinical program, as well as other studies with simufilam.
• General and administrative (G&A) expenses were $4.4 million. This compared to $2.9 million for the same period in 2022. G&A expenses increased due primarily to increased activities and expenses related to legal services.

About Cassava Sciences’ Phase 3 Program
We are conducting a Phase 3 clinical evaluation of simufilam in people with Alzheimer’s disease dementia. This program consists of two on-going, randomized, double-blind, placebo-controlled studies. Both Phase 3 studies have received a Special Protocol Assessment (SPA) from the U.S. Food and Drug Administration. The Phase 3 program is recruiting a total of approximately 1,750 patients with mild-to-moderate Alzheimer’s disease who also meet other study eligibility criteria. Our Phase 3 studies are actively recruiting Alzheimer’s patients in over 100 clinical sites in the United States, Canada, Puerto Rico, South Korea and Australia.

About Simufilam
Simufilam is a novel drug candidate designed to treat and slow the progression of Alzheimer’s disease. Simufilam binds tightly to an altered conformation of the filamin A protein (FLNA) that is present in the brain of the Alzheimer’s patient and is critical to the toxicity of Aβ42. Simufilam is wholly owned by Cassava Sciences, without royalty or payment obligation to any third party.
