Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients enrolled in a medical setting if eligible. Inclusion and exclusion criteria. A total of 20 patients with unexplained refractory epilepsy were screened and tested with a multiple panel for anti-neuronal antibodies.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In comparisons with our original futility criteria, it was apparent that the absence of more powerful findings, and the time it took to collect the ones we have, indicated the virtual impossibility of identifying enough patients with strong autoimmune findings to carry out Phase 2 of this study.
