Abstract:
Substantial efforts are underway toward optimizing the diagnosis, monitoring, and treatment of seizures and epilepsy. We describe preclinical programs in place for screening investigational therapeutic candidates in animal models, with particular attention to identifying and eliminating drugs that might paradoxically aggravate seizure burden. After preclinical development, we discuss challenges and solutions in the design and regulatory logistics of clinical trial execution, and efforts to develop disease biomarkers and interventions that may be not only seizure-suppressing, but also disease-modifying. As disease-modifying treatments are designed, there is clear recognition that, although seizures represent one critical therapeutic target, targeting nonseizure outcomes like cognitive development or functional outcomes requires changes to traditional designs. This reflects our increasing understanding that epilepsy is a disease with profound impact on quality of life for the patient and caregivers due to both seizures themselves and other nonseizure factors. This review examines selected key challenges and future directions in epilepsy diagnostics and therapeutics, from drug discovery to translational application.
Insights
Optimizing epilepsy treatment involves rigorous preclinical screening and innovative clinical trials. Future therapies aim to be disease-modifying, improving quality of life beyond just seizure suppression.
Area of Science:
- Neuroscience
- Pharmacology
- Clinical Medicine
Background:
- Epilepsy diagnosis, monitoring, and treatment require continuous optimization.
- Current approaches focus on seizure suppression, but a broader impact is needed.
Purpose of the Study:
- To review challenges and future directions in epilepsy therapeutics and diagnostics.
- To highlight the shift towards disease-modifying treatments and improved quality of life.
Main Methods:
- Preclinical screening of therapeutic candidates in animal models, focusing on avoiding seizure aggravation.
- Discussion of clinical trial design, regulatory logistics, and biomarker development.
- Examination of strategies for targeting nonseizure outcomes.
Main Results:
- Identification of critical factors in preclinical drug development to prevent paradoxical seizure worsening.
- Analysis of hurdles and solutions in clinical trial execution for epilepsy interventions.
- Emphasis on developing biomarkers and treatments that modify the disease course.
Conclusions:
- Epilepsy treatment is evolving beyond seizure suppression to address the disease's broader impact on quality of life.
- Future therapeutic strategies must incorporate nonseizure outcomes like cognitive and functional improvements.
- A comprehensive approach from drug discovery to translational application is essential for advancing epilepsy care.
