Human Epilepsy Project 2: Resistant Focal Seizures Study

The Epilepsy Foundation is launching a partnership, called the Human Epilepsy Project, in
collaboration with the Epilepsy Study Consortium. This study (which is called HEP2 for short)
is designed to better understand the challenges of living with focal seizures that do not
respond to medication. The HEP2 study will follow 200 people with medication-resistant focal
epilepsy (with seizures that occur at least 4 times per month) over two years to measure
changes in their seizure frequency, treatments used, adverse events experienced, presence of
co-morbidities like depression and anxiety, healthcare costs, and quality of life. Blood
samples will also be collected in order to look for biomarkers of epilepsy severity and
treatment response.

Participants can join the HEP2 study at any one of nine recruiting study centers. These study
centers were selected because they are epilepsy centers with track records of conducting
high-quality research in epilepsy and efficiently recruiting participants into studies. The
designated sites for the HEP2 study are located in New York, California, Minnesota,
Connecticut, Pennsylvania, and Tennessee. The study has one international site in Finland. A
participant may enroll in the HEP2 study but continue to receive their standard epilepsy care
with their current physician, as long as the participant is willing to share his or her
medical records, and travel to the study center for three in person visits at the beginning
of the study, after the first year, and a final visit after the second year.

Inclusion Criteria:

1. Age ≥ 16 years and ≤ 65 years at time of enrollment

2. Diagnosed with focal epilepsy with prior vEEG confirmation; if no VEEG confirmation,
but in the opinion of the investigator the seizures are definite, the case can be
reviewed and adjudicated by the consortium

3. Failure of adequate trials of 4 AEDs, with at least 2 due to failure of seizure
control, including current AEDs

4. Have a seizure frequency of ≥ 4 focal seizures/month, including auras, and at least 2
observable seizures/month, that are countable by the subject and/or caregiver for the
3 months prior to enrollment

5. Able to keep a daily seizure diary, either independently or with assistance from a
caregiver

6. Able to retrospectively report number of seizures/month for 3 months prior to
enrollment

7. Receiving ≥ 1 AED for treatment of seizures

Exclusion Criteria:

1. Patient has a diagnosis of idiopathic ("primary") generalized epilepsy (e.g., juvenile
myoclonic epilepsy, absence epilepsy) or mixed focal and generalized (e.g.,
Lennox-Gastaut syndrome) or non-epileptic seizures within the last 12 months prior to
study entry

2. Progressive medical or neurological disorder (brain tumor, AD, PME, etc.)

3. Proven autoimmune etiology

4. Planning pregnancy in the next 12 months

5. Intent to pursue surgical resection intervention in the next two years

6. Resective surgery and/or RNS/VNS in place less than 12 months prior to enrollment

7. Presence of moderate or greater developmental or cognitive delay (e.g., if an
adolescent, not in self-contained classroom; if IQ is documented, should be ≥ 70)

8. History of chronic drug or alcohol abuse (misuse or excessive use that interferes with
activities of daily living) within the last 2 years

9. Medical, psychiatric or psychosocial condition that would be expected to interfere
with the conduct of the study
