[8-K] CASSAVA SCIENCES INC Reports Material Event

Rhea-AI Filing Summary

Cassava Sciences reported a legal update: on October 23, 2025, the U.S. District Court for the District of Maryland dismissed with prejudice the criminal indictment of Dr. Hoau‑Yan Wang, a former scientific collaborator and advisor to the company. A dismissal with prejudice permanently ends the case and prevents refiling of the same charges.

The company emphasized its support for scientific integrity and noted it is continuing its current program evaluating simufilam as a potential treatment for TSC‑related epilepsy, citing research conducted at numerous institutions. This update addresses a key legal overhang involving a third party while the company maintains focus on its development work.

Final court dismissal removes a legal overhang involving a former collaborator.

The court’s dismissal with prejudice on October 23, 2025 is a definitive legal outcome that closes the case tied to a former advisor to Cassava Sciences. Because the matter involved a third party, the ruling does not change operations directly, but it resolves a headline risk linked to prior allegations.

From a disclosure perspective, the company reiterates support for research integrity and confirms ongoing evaluation of simufilam for TSC‑related epilepsy based on work across multiple institutions. Actual impact on development or partnerships depends on external stakeholders’ responses; the filing presents no new clinical or financial data.

Key item to note is the finality of the dismissal (“with prejudice”), which limits further action on the same indictment. Subsequent filings may provide additional program specifics as they become available.

Dismissal of Indictment of Dr. Hoau-Yan Wang

On October 23, 2025, the United States District Court for the District of Maryland granted the United States’ unopposed motion to dismiss with prejudice the criminal indictment against Hoau-Yan Wang, PhD. Dr. Wang is a former scientific collaborator and advisor to Cassava Sciences, Inc. (“Cassava” or the “Company”) who conducted foundational research relating to the Company's investigational drug, simufilam. Among other things, the dismissed charges had accused Dr. Wang of causing Cassava to submit grant applications to the U.S. National Institutes of Health that allegedly contained false and fraudulent representations about his research and of manipulating or otherwise fabricating research results, including Western Blot images that he prepared. This order permanently terminates the case against Dr. Wang, and future charges related to the dismissed indictment cannot be refiled against Dr. Wang.

Cassava Sciences recognizes and supports the critical importance of integrity in all forms of scientific research. The Company continues to move forward with its current program evaluating simufilam as a potential treatment for Tuberous Sclerosis Complex (TSC)-related epilepsy based on research conducted at numerous institutions.
