5-SENSE Score Validation Study

• Conditions: Epilepsy Intractable
• Interventions: Other: Stereoelectroencephalography (SEEG)

• Registration Number: NCT06138808
• Lead Sponsor: Duke University

Brief Summary

The purpose of this study is to assess how well a new scoring system called the 5-SENSE score can predict where seizures start in the brain using Stereoelectroencephalography (SEEG). The 5-SENSE Score is a 5-point score based on routine presurgical work-up, designed to assist in predicting whether SEEG can identify a focal seizure onset zone, thereby sparing patients the risk of undergoing this invasive diagnostic procedure.

Arm && Interventions

Group	Intervention	Description
Stereoelectroencephalography (SEEG)	Stereoelectroencephalography (SEEG)	Participants undergoing SEEG as part of standard of care.

Primary Outcome Measures

Name	Time	Method
Negative predictive value of the 5-SENSE score for the identification of a focal SOZ on SEEG	At time of SEEG, up to approximately 1 month	Measured for participants undergoing SEEG
Sensitivity of the 5-SENSE score for the identification of a focal SOZ on SEEG	At time of SEEG, up to approximately 1 month	Prospective validation of the predictive value of the 5-SENSE score to identify a focal seizure onset zone (SOZ) in an independent patient sample. Measured for participants undergoing SEEG.
Specificity of the 5-SENSE score for the identification of a focal SOZ on SEEG	At time of SEEG, up to approximately 1 month	Prospective validation of the predictive value of the 5-SENSE score to identify a focal seizure onset zone (SOZ) in an independent patient sample. Measured for participants undergoing SEEG.
Positive predictive value of the 5-SENSE score for the identification of a focal SOZ on SEEG	At time of SEEG, up to approximately 1 month	Measured for participants undergoing SEEG

Secondary Outcome Measures

Name	Time	Method
Concordance of the 5-SENSE Score with the decision whether to proceed with SEEG or not	At enrollment	Before SEEG, the decision whether to proceed with SEEG or not is made blinded from the 5- SENSE Score in a Multidisciplinary Team Discussion (MTD). Following the decision, the 5-SENSE Score will be calculated for each participant by the principal investigator. Concordance of the 5-SENSE Score with the decision made in the MTD will be assessed.
Specificity of the 5-SENSE score augmented by information from auxiliary diagnostic methods for the identification of a focal SOZ on SEEG	At time of SEEG, up to approximately 1 month	For participants undergoing SEEG, information from auxiliary diagnostic methods, performed routinely during presurgical evaluation, namely FDG-PET, electrical source imaging (ESI) and/or magnetic source imaging (MSI) and ictal HMPAO-SPECT will be analyzed. The investigators will assess whether addition of those variables to the 5-SENSE Score could enhance score performance with higher specificity for identifying a focal SOZ
