Trial Information

IVIG Treatment for Refractory Immune-Related Adult Epilepsy

The study is divided into two phases:

Phase I: The investigators will screen for evidence of neuronal nuclear, cytoplasmic, and
cell surface autoantibodies in our population of new onset refractory, imaging-negative
young adult epilepsy patients. This part of the study involves obtaining a single blood
sample, equal to about 2 teaspoons.

Phase 2: If a sufficient number of cases are identified, a double-blind crossover study of
IVIG treatment will be performed in these patients.

Inclusion Criteria:

- Diagnosis of uncontrolled epilepsy with at least two seizures a month for three
consecutive months.

- Age 18 to 50.

- Clinical semiology or electroencephalogram (EEG) consistent with partial onset

- Refractory to an adequate trial of two or more main-line anti-epileptic drugs.

- Ability to keep a seizure diary.

- Normal brain magnetic resonance imaging (MRI) - 3 Tesla, seizure protocol; with the
exception of hippocampal sclerosis

Exclusion Criteria:

- History of severe prematurity or neonatal distress, febrile seizures, moderate or
sever traumatic brain injury, stroke, brain tumor, meningitis, encephalitis,
neurocutaneous syndromes, or intracranial metal objects.

- Evidence of psychogenic epilepsy.

- History of convulsive status epilepticus.

- History of primary generalized epilepsy in a first degree relative.

- Known serious medical illness.
