Consortium.

2. Is male or female, aged 18 to = 70 years at screening.

3. Is able to read, understand, and sign the Informed Consent Form (ICF). If the
participant is unable to sign informed consent, a Legally Authorized Representative
(LAR) will complete the ICF.

6. Is able to swallow capsules whole without crushing, chewing, or cutting.

7. Is willing to adhere to all study procedures and able to attend study visits within
the specified time windows.

8. Failure of at least 2 tolerated, appropriately chosen and adequately dosed ASM drug
schedules to achieve sustained seizure freedom.

9. Taking at least 1 ASM at Screening and Baseline.

10. At least 4 seizures accepted by the Epilepsy Study Consortium for the secondary
outcome (adjudicated as "probable seizures" that are countable) during the 42-day
baseline seizure diary period, and no more than a 21-day period that was seizure-free.

11. A clinical diagnosis of Focal Cortical Dysplasia (FCD) Type I or Type II
(approximately n=10) confirmed by:

1. Likely FCD supported by neuroimaging that has been performed in the last 5 years,
or

2. History of surgical resection of the cortical dysplasia that is
histopathologically confirmed in patients who continue to have uncontrolled
seizures without a compelling alternate explanation for ongoing seizures.

Note: The Epilepsy Study Consortium will review to confirm FCD/probable FCD diagnosis.

12. Be in good general health in the judgment of the PI based upon medical history,
physical examination, standard 12-lead ECG, and clinical laboratory evaluations
obtained during the Screening Period

13. Be able to comply with all study-specified procedures.

14. Non-pregnant females of childbearing potential (FOCP) who are either sexually inactive
(abstinent) or, if sexually active with a male partner who is biologically capable of
having children, must agree to use one of the following acceptable birth control
methods beginning 30 days prior to the first dose of SPN-817, throughout the study,
and for 30 days following the last dose:

1. Simultaneous use of male condom and intra-uterine contraceptive device (IUD)
placed at least 4 weeks prior to first SPN-817 administration

2. Surgically sterile male partner

3. Simultaneous use of male condom and diaphragm with spermicide

4. Established hormonal contraceptive

Females are considered not to be of childbearing potential if they are either
post-menopausal (amenorrhea for at least 2 years and serum follicle stimulating
hormone [FSH] level of >40 IU/L) or permanently sterilized (e.g., bilateral tubal
ligation, hysterectomy, bilateral oophorectomy) for 6 months minimum.

15. Males must:

1. Use 2 methods of contraception in combination if his female partner is of
childbearing potential; this combination of contraceptive methods must be used
from the Screening Visit to = 1 month after the last dose of SPN-817, or

2. Have been surgically sterilized prior to the Screening Visit.

3. Refrain from donating any sperm until completion of the EOS Visit.

16. Patients who were previously enrolled in the BNI-02-1b FIAS study and benefited from
the treatment, following the approval by both the PI and the sponsor to be enrolled in
this study.
Minimum age
18 Years
Maximum age

epileptic seizures.

5. Has only seizures that are difficult to count; for example, has seizures that are not
clinically observable.

multiple seizures with at least one seizure within 30 minutes of the previous seizure.

patient's safety, based on what is known about the pharmacology/toxicology profile of
the trial agent(s).

12. Has a pre-existing medical condition (including an existing progressive or
degenerative neurological disorder including brain tumor, active encephalitis, active
meningitis or abscess) or takes medications that, in the PI's opinion, could interfere
with the patient's suitability for participation in the study.

13. Has a history or evidence of current significant psychiatric disturbance (e.g.,
schizophrenia, schizoaffective, or bipolar disorder) that would preclude meaningful

5. Second or third-degree atrioventricular block

6. Any rhythm, other than sinus rhythm, that is interpreted by the investigator to
be clinically significant

22. Creatinine clearance < 90 mL/min, according to the Cockcroft-Gault equation at
Screening.

23. Clinically significant vital sign abnormalities (systolic blood pressure lower than 90
or over 140 mmHg, diastolic blood pressure lower than 50 or over 90 mmHg, or HR less
than 50 or over 100 bpm) at Screening.

24. Patient has had greater than 2 allergic reactions to an ASM or one serious
hypersensitivity reaction to an ASM.
