Brief summary
The goal of this interventional study is to develop a personalized seizure risk forecast tool in people with epilepsy. The main questions it aims to answer are: * can we develop a future seizure probabilities tool that is more accurate than chance based on the pattern and frequency of previous generalized tonic-clonic seizure (GTCS) events, as well as changes in physiological and behavioral variables. * does this tool improve the lives of people with epilepsy? Researchers will compare a group that does not have access to the forecast tool to a group that does and see if it is accurate and if people with it report that it improved their quality of life.
Detailed description
The primary goal of the study is to demonstrate the accuracy of SeizureWise in predicting the timing of future convulsive seizures using data collected by the wearable EmbracePlus device and data provided by patients with GTCS monitored in outpatient settings. The secondary goals are: to assess the clinical impact of SeizureWise on quality of life (QoL), psychological health indicators, and economic and clinical outcomes to assess the clinical impact of visualizing behavioral and physiologic data without forecasting predictions on quality of life (QoL), psychological health indicators, and economic and clinical outcomes A non-significant risk, open-label, prospective, randomized clinical investigation designed to evaluate the ability of SeizureWise to forecast GTCS occurrence and to assess impact on QoL and seizure management outcomes. The study will include two phases during which an algorithm based on sensor derived physiological measures is developed and tested with output blinded to the participant. In a final phase participants will be randomized to two arms, one of which will have access to a seizure forecasting risk score.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity of SeizureWise | 2 years | Percentage of patients with (1) sensitivity of high-likelihood warnings greater than 60% and (2) superior to a rate-matched forecast (or superior baselining method) at the end of Phase 2. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Qualitative assessment of multi-day visualizations | 2 years | Patient-reported qualitative assessment of multi-day visualizations to the patient during Phase 3 (both arms). This will be assessed using a custom survey and a qualitative analysis of the scores will be performed between start of phase 3 (with no visualizations) and during and at the end of phase 3 when visualizations have been provided to the user. |
| Stress level with visualizations using the brief epilepsy anxiety survey instrument (brEASI-8) | 2 years | Quantitative patient report of stress level pre- and post- forecast visualization during Phase 3 in the intervention arm. This will be assessed using brEASI-8 where a lower score indicates a lower stress level. |
| Change in QoL and psychological health indicators using the Quality of life in epilepsy (QOLIE-10-P) | 2 years | Changes in QoL and psychological health indicators pre- and post-Phase 3 (cross-arm and intra-arm comparisons. This will be assessed using the QOLIE-10-P and scored according to these guidelines https://www.aan.com/siteassets/home-page/policy-and-guidelines/quality/quality-measures/epilepsy-and-seizures/qolie10p-scoring.pdf |
| Accuracy of SeizureWise low-likelihood forecast | 2 years | Percentage of time in a low-likelihood forecast category during which no seizure event occurs during Phase 2. |
| Accuracy of SeizureWise high-likelihood forecast | 2 years | Percentage of time in a high-likelihood forecast category during which a seizure event occurs during Phase 2. |
| Modifiable behavior change | 2 years | Adjustment in modifiable behaviors during Phase 3 based on multi-day visualizations (boths arms) and forecast outputs (intervention arm). This will be assessed using a custom survey and a qualitative analysis will be performed that looks at participants behaviors before and after receiving visualizations and SeizureWise. |
