Human Epilepsy Project 2: Resistant Focal Seizures Study

  • Study HIC#:2000022824
  • Last Updated:07/15/2021

The Human Epilepsy Project2 (HEP2) is a prospective, observational study whose primary goal is to identify clinical characteristics and biomarkers predictive of disease outcome, progression, and treatment response in participants with treatment-resistant focal epilepsy. The data to be collected on these participants include high-resolution clinical phenotyping (including comorbidities) and treatment response, neuroimaging reports, electrophysiology reports, and biosamples for genomics, proteomics, metabolomic and transcriptome analyses. A major objective of the project is to create an open data repository of clinical information and biologic samples for future studies.

Trial Purpose and Description

The Human Epilepsy Project 2: Resistant Focal Seizures Study (HEP2 for short) is a research project to better understand what happens over time in people with focal seizures that don’t respond to current treatment.

 This is a two year, observational study. The study will not affect the treatment of your seizures in any way. We estimate that approximately 200 people will take part in this study.  

 If you decide to take part in this study, you will have 2-3 in person study visits, which will take place over the next 2 years. We will collect blood samples from you at the beginning and the end of the study. With these samples, we will try to find markers that help us better understand why you are having seizures and to determine which of these markers predict what happens with your condition in the future. We will also ask you to complete some online questionnaires, have once-a-month check in calls with the study coordinator, and to keep a daily seizure diary.     

There is no cost for you to participate in this study. You will receive compensation at each annual visit. Although you may not benefit directly from taking part in this study, you will contribute to the knowledge we gain from participants in this study that could help individuals with epilepsy in the future.
