Filana Therapeutics Reports Fourth Quarter and Full Year 2025 Financial Results

Working to advance TSC-related epilepsy program, with a focus on capital efficiency

AUSTIN, Texas, March 12, 2026 (GLOBE NEWSWIRE) -- Filana Therapeutics, Inc. (formerly Cassava Sciences, Inc.) (NASDAQ: FLNA, “Filana Therapeutics”, the “Company”), a biotechnology company focused on developing novel medicines to modulate the filamin A protein for the treatment of central nervous system (CNS) disorders, such as Tuberous Sclerosis Complex (TSC)-related epilepsy, and other diseases associated with dysregulation or overexpression of filamin A, today reported financial results for the fourth quarter and year ended December 31, 2025, and provided a business update.

Net loss for 2025 was $91.0 million, or $1.88 per share, compared to a net loss of $24.3 million, or $0.53 per share (basic), in 2024. Net cash used in operations was $32.3 million in 2025, consistent with previous guidance.

The Company met cash guidance for year-end 2025, reporting $95.5 million, and estimates cash at June 30, 2026 in a range from $47 to $50 million. The Company estimates net cash use in operations for first half of 2026 in a range from $14 to $17 million, plus a payment of a $31.25 million estimated loss contingency related to the potential settlement of certain securities litigation recorded in 2025.

“At Filana Therapeutics, our name reflects our deep commitment to science and to patients affected by diseases tied to filamin A dysregulation, including TSC-related epilepsy. We are driven by the urgent need for new treatment options that can meaningfully improve patients’ lives,” said Rick Barry, President and Chief Executive Officer of Filana Therapeutics, Inc. “In partnership with our advisors, we are working diligently to address the FDA’s requests and look forward to sharing a progress update in the coming months.”

Corporate Updates:

• Name change to Filana Therapeutics, Inc.: Filana Therapeutics’ new name and brand reflect the Company’s strategic focus on developing novel medicines to modulate the filamin A protein for the treatment of CNS disorders, such as TSC-related epilepsy, and other diseases associated with dysregulation or overexpression of filamin A.
• TSC Program Update: The Company is actively addressing FDA’s request for information detailed in the Clinical Hold Letter received in December 2025, including the submission of additional pre-clinical data and protocol design modifications. The Company intends to submit a response to FDA as soon as practicable.
  
  

Financial Results for the Fourth Quarter and Full Year 2025:

• Cash and cash equivalents were $95.5 million, with no debt, as of December 31, 2025. This compares to cash and cash equivalents of $128.6 million at December 31, 2024. The Company estimates cash at June 30, 2026, in a range from $47 to $50 million.
• Total shares outstanding as of March 9, 2026, were 48.3 million.
• Net loss for the year ended December 31, 2025, was $91.0 million, or $1.88 per share. This compares to a net loss of $24.3 million, or $0.53 per share (basic) for the same period in 2024. Net loss increased primarily due to a $108.1 million gain in 2024 from change in fair value of warrant liabilities that was not repeated in 2025.
• Net cash used in operations was $32.3 million in 2025, consistent with previous guidance. The Company estimates net cash use in operations for first half of 2026 in a range from $14 to $17 million, plus a payment of $31.25 million estimated loss contingency related to the potential settlement of certain securities litigation recorded in 2025.
• Research and development (R&D) expenses for the year ended December 31, 2025, decreased to $26.6 million from $69.6 million in 2024, representing a 62% reduction. This decrease was due primarily to the phase out of the Alzheimer's disease (AD) development program beginning the fourth quarter 2024 and completed in second quarter 2025. The Company’s planned clinical program in TSC-related epilepsy is expected to cost significantly less than the discontinued AD program.
• General and administrative (G&A) expenses for the year ended December 31, 2025, decreased to $68.8 million from $71.8 million in 2024. The 4% decrease was due primarily to a $40.0 million SEC-related loss contingency recorded in 2024, which was partially offset by $9.9 million in insurance recoveries. This compared to a $31.3 million securities litigation loss contingency and $4 million of other litigation contingencies recorded in 2025, for which there were no insurance recoveries. The change also included a $2.6 million increase in stock-based compensation expense due to new awards granted in late 2024, as well as cost decreases as severance costs recorded in the prior year were not repeated in 2025. 
  
  

About TSC and TSC-related Epilepsy

TSC is a rare genetic disorder resulting from a mutation in the TSC1 or TSC2 gene. This affects the mechanistic target of rapamycin (mTOR) pathway and can cause tumors to grow in multiple organs¹. Epilepsy is the most common health issue affecting the TSC community, with 80% to 90% of TSC patients experiencing seizures¹. TSC-related epilepsy affects approximately 45,000 people in the U.S.² Most patients start having seizures within their first year of life³. Even with multiple approved treatments, more than 60% of TSC patients remain refractory to antiepileptic therapy⁴.

All of our pharmaceutical assets under development are investigational product candidates. These have not been approved for use in any medical indication by any regulatory authority in any jurisdiction and their safety, efficacy or other desirable attributes, if any, have not been established in any patient population. Consequently, none of our product candidates is approved or available for sale anywhere in the world.

Our clinical results from earlier-stage clinical trials or preclinical studies may not be indicative of future results from later-stage or larger scale clinical trials and do not ensure regulatory approval. You should not place undue reliance on these statements or any scientific data we present or publish.

We are in the business of new drug discovery and development. Our research and development activities are long, complex, costly and involve a high degree of risk. Holders of our common stock should carefully read our Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q in their entirety, including the risk factors therein. Because risk is fundamental to the process of drug discovery and development, you are cautioned to not invest in our publicly traded securities unless you are prepared to sustain a total loss of the money you have invested.
