Item 8.01. Other Events.

FDA Clinical Hold Lifted

On September 22, 2026, the Company announced that the U.S. Food and Drug Administration has lifted the full clinical hold on the Company’s investigational new drug (IND) application to initiate a planned Phase 2a proof-of-concept study for simufilam in tuberous sclerosis complex (“TSC”)-related epilepsy.

Planned Phase 2a Trial Design

During the course of the clinical hold, the Company completed key trial-readiness activities, including engaging a leading clinical research organization, identifying clinical trial sites, and recruiting potential investigators. With investigational drug supply in place, implementation of the Company’s phase 2a study of simufilam is now able to progress expeditiously toward site initiation and patient enrollment. Patient screening is expected to begin by the first quarter of 2027.

Filana’s Phase 2a study is a 16-week multicenter, randomized, double-blind clinical trial to evaluate two doses of simufilam in patients with refractory TSC-related seizures. The study is planned to be conducted at 13 sites in the U.S. with a target enrollment of 40 subjects aged 12 to 55. All subjects who complete the double-blind treatment phase are eligible to participate in a 48-week extension study.

The study is designed to assess safety, tolerability, pharmacokinetics, and seizure-related measures, including seizure frequency, seizure intensity and duration, nighttime seizures, and sleep-related outcomes. Data from the study are expected to help inform the development path for simufilam in TSC-related epilepsy, including the design of future studies in younger patient populations.

Cautionary Note Regarding Forward-Looking Statements:

This report contains forward-looking statements that may include but are not limited to statements regarding: the timing and plans to initiate and conduct clinical studies with simufilam in TSC-related epilepsy; the design, structure, duration, objectives, endpoints, patient population, conduct, enrollment, completion, and potential results of the Company’s planned Phase 2a clinical trial; the Company’s ability to work with clinical research organizations, clinical sites, patient advocacy organizations, and the TSC community to advance the trial efficiently; the potential for simufilam as a treatment for TSC-related epilepsy and other potential indications; and the timing of anticipated milestones, including announcing study sites and screening patients. These statements may be identified by words such as “anticipate”, “before”, “believe”, “could”, “expect”, “forecast”, “intend”, “may”, ”pending”, “plan”, “possible”, “potential”, “prepares for”, “will”, and other words and terms of similar meaning.

Such statements are based on the Company’s current expectations and projections about future events. Such statements speak only as of the date of this news release and are subject to a number of risks, uncertainties and assumptions, including, but not limited to, those risks relating to the Company’s ability to initiate, enroll, conduct, and complete the planned Phase 2a study of simufilam in TSC-related epilepsy; the Company’s ability to engage clinical trial sites and participants; ability to work effectively with clinical research organizations, vendors, investigators, patient advocacy organizations, and the TSC community; potential changes to the clinical trial protocol, trial design, endpoints, timing, patient population, or development plans; the Company’s ability to generate clinical data that support further development of simufilam; risks inherent in drug discovery and development; and other risks specific to Filana Therapeutics, Inc., as described in the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 and subsequent reports to be filed with the SEC. The foregoing sets forth many, but not all, of the factors that could cause actual results to differ from expectations in any forward-looking statement.
