Dravet症候群（DS）概述

Dravet症候群，又稱重症嬰兒肌陣攣性癲癇，是一種罕見且難治的遺傳性癲癇，通常在出生後第一年內發病。此病以頻繁、持續時間長的癲癇發作為特徵，常由發燒或體溫升高（例如溫水浴）誘發，並最終發展為多種類型的癲癇發作，包括肌陣攣性發作和非典型失神發作。約80-85%的病例是由SCN1A基因的突變或缺失引起的，該基因編碼Nav1.1電壓門控鈉通道，該通道對抑制性神經元功能至關重要。大多數此類突變是自發性的，但少數屬於GEFS+家族頻譜，其他病例可能涉及PCDH19基因突變或體細胞嵌合。除癲癇發作外，此症候群還伴隨顯著的發育遲緩、共濟失調、肌張力低下和睡眠障礙。由於常見的鈉通道阻斷劑可能會異常增加癲癇發作的頻率，因此治療特別複雜，要更好地控制癲癇發作可能需要使用特定的療法，例如司替戊醇、芬氟拉明或大麻二酚。

主要亮點

• 在德國，經確診的 Dravet 症候群突變病例數預計將從 2025 年的 1749 例增加到 2035 年的 1781 例。
• Dravet 症候群是一種嚴重的神經發育障礙和癲癇性腦病變，通常由 SCN1A 基因突變引起。
• 患者表現出難治性癲癇和嚴重的神經發育障礙。
• 標靶治療的廣泛應用提高了癲癇控制效果和患者預後。

Dravet Syndrome (DS) Market Outlook

Thelansis's "Dravet Syndrome (DS) Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report - 2025 To 2035" covers disease overview, epidemiology, drug utilization, prescription share analysis, competitive landscape, clinical practice, regulatory landscape, patient share, market uptake, market forecast, and key market insights under the potential Dravet Syndrome treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).

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.
