Key Takeaways from the Developmental and Epileptic Encephalopathies Market Report
• In March 2025, Longboard Pharmaceuticals announced a DEEp OCEAN Study is a double-blind, randomized, placebo-controlled, multicenter study to investigate the efficacy, safety, and tolerability of LP352 in the treatment of seizures in children and adults with DEE. The study consists of 3 main phases: Screening, Titration period, Maintenance period, followed by a Taper period and Follow-Up. The total duration of the study will be approximately 24 months.
• The total number of diagnosed prevalent cases of DEE in the 7MM was nearly 284,000 cases in 2023 and are projected to increase during the forecasted period.
• Lennox-Gastaut syndrome (LGS) and Tuberous sclerosis complex (TSC) asscociated epilepsy are the largest contributors to the overall DEE pool. The prevalent cases of DEE in the United States were nearly 50,000 for LGS and nearly 47,100 for TSC with epilepsy in 2023.
• The total number of cases in EU4 and the UK for DEE was estimated to be nearly 104,000 cases in 2023.
• Among EU4 and the UK, the highest number of cases for DEE was found in Germany which was estimated to nearly 34% of cases in EU4 and the UK in 2023.
• The total number of cases in Japan for DEE was estimated to be nearly 34,000 cases in 2023.

Developmental and Epileptic Encephalopathies Marketed Drugs
• EPIDIOLEX: Jazz Pharmaceuticals
EPIDIOLEX, also known as EPIDYOLEX in Europe, is the first prescription, plant-derived oral formulation developed by GW Pharmaceuticals. It is a novel class of antiepileptic medications with a different mechanism of action. The drug is the first FDA-approved drug that contains a purified drug substance derived from marijuana, and the active ingredient. Under the Controlled Substances Act (CSA), classified as a Schedule I substance; thus, GW Pharmaceuticals conducted nonclinical and clinical studies to assess the abuse potential to support its usage.

• FINTEPLA (fenfluramine): UCB
FINTEPLA (formerly known as ZX008) is an oral medication that is a low-dose solution of fenfluramine hydrochloride. It prevents the entry of calcium ions into nerve cells, lowering their over-excitability and reducing seizure episodes. It also activates serotonin receptors, which contribute to the overall antiepileptic action.

Developmental and Epileptic Encephalopathies Emerging Drugs
• Zorevunersen (STK-001): Stoke Therapeutics
Zorevunersen is an investigational new medicine for the treatment of Dravet syndrome. It is a proprietary antisense oligonucleotide (ASO) and has the potential to be the first disease-modifying therapy to address the genetic cause of Dravet syndrome. The drug is designed to upregulate NaV1.1 protein expression by leveraging the non-mutant copy of the SCN1A gene to restore physiological NaV1.1 levels, thereby reducing both occurrences of seizures and significant non-seizure comorbidities.

• Bexicaserin (LP352): Longboard Pharmaceuticals
Bexicaserin is an oral, centrally acting, 5-HT2c superagonist in development for the potential treatment of seizures associated with DEEs such as Dravet syndrome, LGS, tuberous sclerosis complex (TSC), CDKL5 deficiency disorder (CDD), and other epileptic disorders. LP352 is designed to modulate GABA and, as a result, suppress the central hyperexcitability that is characteristic of seizures. LP352 is the only 5-HT2c receptor superagonist being dose-optimized for the refractory epilepsy population.

Developmental and Epileptic Encephalopathies Market Outlook
In recent years, three antiseizure medications have been approved as adjunct therapy in patients with Dravet Syndrome: DIACOMIT (Stiripentol), which was approved in the US in 2018 and received full European marketing authorization in 2014, EPIDIOLEX which was approved by the FDA in 2018, and FINTEPLA (fenfluramine), which was approved in 2020 in the US and EU. These treatments are "add-on" therapies (most usually used in conjunction with Valproate and clobazam) with availability and recommendations in various countries influencing the decision in the EU.

Developmental and Epileptic Encephalopathies Drugs Market
Disease-modifying therapies represent a significant leap forward in the treatment of Developmental and Epileptic Encephalopathies (DEE). These innovative approaches have the potential to transform the landscape of care, offering new hope to patients and families affected by these challenging conditions. For instance, if approved, STK-001 could become the first disease-modifying medicine for Dravet syndrome, a severe form of epilepsy. This breakthrough would not only address the symptoms but also target the underlying causes of the disease, marking the dawn of a new era in DEE treatment.
