Dravet Syndrome (DS) Emerging Therapy and TPP Insights

Thelansis's "Dravet Syndrome (DS) Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026" provides a comprehensive analysis of the emerging competitive landscape, unmet needs, target product profiles (TPPs), trial designs, and KOL insights on key emerging therapies and key drug development opportunities in the indication.

Dravet Syndrome (DS) Overview

Dravet syndrome, also known as severe myoclonic epilepsy of infancy, is a rare and refractory genetic epilepsy that typically begins in the first year of life. The disorder is primarily characterized by frequent, prolonged seizures often triggered by hyperthermia, such as fevers or warm baths, and eventually progresses to include multiple seizure types including myoclonic and atypical absence seizures. Approximately 80 to 85 percent of cases result from a mutation or deletion in the SCN1A gene, which encodes the Nav1.1 voltage-gated sodium channel essential for the function of inhibitory neurons. While most of these mutations occur spontaneously, a small percentage are part of the GEFS+ familial spectrum, and other cases may involve mutations in the PCDH19 gene or somatic mosaicism. In addition to seizures, the syndrome is associated with significant developmental delays, ataxia, hypotonia, and sleep disturbances. Management is particularly complex because common sodium-channel-blocking medications can paradoxically increase seizure frequency, requiring the use of specific treatments such as stiripentol, fenfluramine, or cannabidiol to achieve better seizure control.

Key Highlights

• In Germany, mutation-positive Dravet Syndrome cases are projected to increase from 1,749 in 2025 to 1,781 by 2035.
• Dravet Syndrome is a severe developmental and epileptic encephalopathy typically caused by SCN1A mutations.
• Patients experience treatment-resistant seizures and substantial neurodevelopmental impairment.
• Increasing use of targeted therapies is improving seizure control and patient outcomes.
