• CUNY’s report makes no findings of data manipulation.
• The “egregious misconduct” cited in the report relates to internal record-keeping failures at CUNY.
• CUNY’s report finds that internal record-keeping failures “prevented us [CUNY] from making an objective assessment” of research misconduct.
• Leak of CUNY report preceded by massive increase in short selling.

AUSTIN, Texas, Oct. 12, 2023 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, today issued the following statement regarding an internal report purportedly prepared by City University of New York (CUNY). This report was leaked to the press. The leak of the CUNY report was preceded by a 40% increase in short selling activity in the stock of Cassava Sciences.

Beginning August 2021, short sellers executed a brutal, widely publicized “short-and-distort” campaign against Cassava Sciences. The short-sellers alleged that Cassava Sciences and its academic researcher at CUNY had engaged in data manipulation and other forms of research misconduct. In response to these allegations, CUNY initiated an internal investigation in Fall 2021. In 2022, Cassava Sciences filed a lawsuit against certain individuals who participated in the short-and-distort campaign, identifying over 1,000 false and defamatory statements.

On October 12, 2023, Science reported that it had obtained a copy of CUNY’s report from “a person who requested anonymity because they are not authorized to share it.” The Science article quotes a person paid by a lawyer for certain short-sellers, but does not indicate what role, if any, short-sellers had in the leak. According to Science, CUNY completed its investigation in May 2023. The short interest in Cassava Sciences’ stock jumped 40%, to over 14 million shares, between June 30, 2023, and September 29, 2023, according to NASDAQ.

CUNY’s report makes no findings of data manipulation. Rather, the “egregious misconduct” cited in the report relates exclusively to internal record-keeping failures at CUNY. The report also finds that internal record-keeping failures “prevented us [CUNY] from making an objective assessment” of the allegations of research misconduct.

“We remain confident in the underlying science for simufilam, our lead drug candidate,” said Remi Barbier, President & CEO. “We intend to continue to translate our passion for science into a novel drug for people living with Alzheimer’s disease. Our Phase 3 clinical program continues.”

Cassava Sciences played no role in CUNY’s investigation. The university turned down all requests for information and offers of assistance from Cassava. Because CUNY did not interview any employee of Cassava Sciences, the university has no legitimate basis on which to make accusations against the Company or its employees.

CUNY has not responded to an inquiry Cassava Sciences made yesterday regarding the authenticity of the leaked report.

Importantly, Cassava Sciences does not rely exclusively on research at CUNY. The science underlying simufilam, Cassava Sciences’ lead drug candidate, is supported by the work of scientists at academic institutions that have no connection to CUNY, including:

• In September 2023, Cassava Sciences announced the publication of new research that confirms the biological activity of simufilam. Researchers at the Cochin Institute (Paris, France) used a highly precise cell-based assay to show that simufilam interrupts amyloid binding to the α7 nicotinic acetylcholine receptor. Cassava Sciences believes this protein interaction underlies simufilam’s mechanism of action in Alzheimer’s disease. The research appears in a special issue of International Journal of Molecular Sciences, a peer-reviewed scientific publication, and is currently available on-line at: https://www.mdpi.com/1422-0067/24/18/13927
• In May 2023, Cassava Sciences announced the publication of new data that highlights the biological activity of simufilam on Filamin A. Researchers at the University of Milan (Italy) showed a functional interaction between simufilam, filamin A (FLNA) and somatostatin receptors. Specifically, the researchers showed that simufilam treatment significantly reduced levels of phosphorylation at a site on FLNA in human pituitary tumor cells. The research was presented at the 25^th European Congress of Endocrinology and is currently available on-line at: https://www.endocrine-abstracts.org/ea/0090/ea0090oc7.5

• In February 2020, Cassava Sciences announced that filamin A inhibition by simufilam reduced seizure activity in a mouse model of epilepsy. The data was generated by researchers at Yale University, was published in Science Translational Medicine and is currently available on-line at: https://pubmed.ncbi.nlm.nih.gov/32075941/

Other independent researchers have shown a role for filamin A in neurodegeneration.
