BEDFORD, Mass.--(BUSINESS WIRE)--Stoke Therapeutics, Inc. (Nasdaq: STOK) is a biotechnology company dedicated to restoring protein expression by harnessing the body’s potential with RNA medicine and has a lead investigational medicine, zorevunersen, in development as a first-in-class potential disease-modifying treatment for Dravet syndrome. The Company today reported financial results for the first quarter ended March 31, 2025, and provided business updates. “The first quarter was defined by strong execution as we advance zorevunersen into Phase 3 development for Dravet syndrome,” said Ian F. Smith, Interim Chief Executive Officer and Director of Stoke Therapeutics. “With regulatory alignment on a global Phase 3 study, a strategic collaboration with Biogen, and a balance sheet that takes the company to launch readiness, we are well-positioned to deliver the first disease-modifying therapy for Dravet syndrome to patients worldwide who need it while also continuing to invest in our pipeline.” Recent Program Highlights and Upcoming Milestones The Company plans to initiate EMPEROR in the second quarter of 2025 with an expected data readout in the second half of 2027, which is anticipated to support global regulatory filings. In February, the Company entered into a collaboration with Biogen to develop and commercialize zorevunersen for the treatment of Dravet syndrome for which Stoke received $165 million upfront. The parties will share external clinical development costs for zorevunersen (30 percent Biogen; 70 percent Stoke). Additionally, Stoke may receive up to $385 million in development and commercial milestone payments and be eligible to receive tiered royalties ranging from low double digits to high teens on potential net sales in the Biogen territory. Stoke retains exclusive rights for zorevunersen in the United States, Canada, and Mexico. Biogen receives exclusive rest of world commercialization rights. (For full details, see the press release ). In January, the Company announced plans to initiate a global Phase 3 registrational study of zorevunersen (EMPEROR) for the treatment of Dravet syndrome following successful alignment with the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA) and Japan’s Pharmaceuticals and Medical Devices Agency (PMDA). The study design is based on positive clinical data from Phase 1/2a and open label extension studies that showed continuing improvements in cognition and behavior in addition to substantial and durable reductions in major motor seizure frequency. The study will evaluate two loading doses of 70mg followed by two maintenance doses of 45mg over 52 weeks compared to sham in children and adolescents ages 2 to <18 with Dravet syndrome. The primary endpoint will be reduction in major motor seizure frequency. Key secondary endpoints will include improvements in cognition and behavior as measured primarily by Vineland-3. (For full details, see the press release ).

About Dravet Syndrome Dravet syndrome is a severe developmental and epileptic encephalopathy characterized by severe, recurrent seizures as well as significant cognitive and behavioral impairments. Most cases of Dravet are caused by mutations in one copy of the SCN1A gene, leading to insufficient levels of NaV1.1 protein in neuronal cells in the brain. More than 90 percent of patients continue to experience seizures despite treatment with the best available anti-seizure medicines. Complications of the disease often contribute to a poor quality of life for patients and their caregivers. Developmental and cognitive impairments often include intellectual disability, developmental delays, movement and balance issues, language and speech disturbances, growth defects, sleep abnormalities, disruptions of the autonomic nervous system and mood disorders. Compared with the general epilepsy population, people living with Dravet syndrome have a higher risk of sudden unexpected death in epilepsy, or SUDEP. Dravet syndrome occurs globally and is not concentrated in a particular geographic area or ethnic group. Currently, it is estimated that up to 38,000 people are living with Dravet syndrome in the U.S., UK, EU-4 and Japan. About Zorevunersen Zorevunersen is an investigational antisense oligonucleotide that is designed to treat the underlying cause of Dravet syndrome by increasing NaV1.1 protein production in brain cells from the non-mutated (wild-type) copy of the SCN1A gene. This highly differentiated mechanism of action aims to reduce seizure frequency beyond what has been achieved with anti-seizure medicines and to improve neurodevelopment, cognition, and behavior. Zorevunersen has demonstrated the potential for disease modification and has been granted orphan drug designation by the FDA and the EMA. The FDA has also granted zorevunersen rare pediatric disease designation and Breakthrough Therapy Designation for the treatment of Dravet syndrome with a confirmed mutation not associated with gain-of-function, in the SCN1A gene. About Stoke Therapeutics Stoke Therapeutics (Nasdaq: STOK), is a biotechnology company dedicated to restoring protein expression by harnessing the body’s potential with RNA medicine. Using Stoke’s proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) approach, Stoke is developing antisense oligonucleotides (ASOs) to selectively restore naturally-occurring protein levels. Stoke’s first medicine in development, zorevunersen, has demonstrated the potential for disease modification in patients with Dravet syndrome and is expected to enter Phase 3 development in 2025. Stoke’s initial focus are diseases of the central nervous system and the eye that are caused by a loss of ~50% of normal protein levels (haploinsufficiency). Proof of concept has been demonstrated in other organs, tissues, and systems, supporting broad potential for the Company’s proprietary approach. Stoke is headquartered in Bedford, Massachusetts, with offices in Cambridge, Massachusetts. For more information, visit https://www.stoketherapeutics.com/.

EPIDIOLEX has significant market potential due to the growing demand for alternative therapies and its effectiveness in treating rare seizure disorders like Lennox-Gastaut syndrome and Dravet syndrome. As awareness around the benefits of CBD in treating neurological conditions increases, EPIDIOLEX stands to benefit from expanding indications and market reach. LAS VEGAS, May 1, 2025 /PRNewswire/ -- DelveInsight's ' EPIDIOLEX Market Size, Forecast, and Market Insight Report' highlights the details around EPIDIOLEX, the first FDA-approved prescription cannabidiol (CBD) to treat seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome, or tuberous sclerosis complex (TSC) in patients 1 year of age or older. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of EPIDIOLEX. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. Jazz Pharmaceuticals' EPIDIOLEX (cannabidiol) Overview EPIDIOLEX (formerly known as GWP42003-P and marketed as EPIDYOLEX in Europe) is the first plant-based, prescription cannabis-derived oral medication developed by GW Pharmaceuticals. It represents a new category of antiepileptic drugs with a unique mechanism of action. The active compound, cannabidiol (CBD), is a naturally occurring cannabinoid found in the Cannabis sativa L. plant. While the exact way EPIDIOLEX works to reduce seizures in humans remains unclear, it is distinct from traditional anticonvulsants. CBD does not act through CB1 receptors or by blocking voltage-gated sodium channels, which are typical pathways for other antiepileptic drugs. Instead, CBD is thought to work by influencing multiple internal pathways, potentially producing a combined anticonvulsant effect. These include enhancing neuronal inhibition (through synaptic and extrasynaptic GABA channels), affecting intracellular calcium levels (via TRPV channels, VDAC, and GPR55), and reducing inflammation, possibly via adenosine modulation. Importantly, CBD does not directly bind to or activate the CB1 or CB2 receptors at levels relevant to its seizure-reducing effects. Ongoing research is examining other possible mechanisms such as interactions with adenosine, glycine, GABAergic systems, and serotonin receptors. EPIDIOLEX has received regulatory approval in numerous countries, including the U.S. (FDA), Europe (European Commission), Great Britain (MHRA), Australia (Therapeutic Goods Administration), Switzerland (Swissmedic), Israel (Ministry of Health), and New Zealand (Medicines and Medical Devices Safety Authority). It is formulated as an oral solution containing highly purified CBD. In the U.S., it is approved to treat seizures linked to Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and tuberous sclerosis complex (TSC) in patients aged one year and older. In the European Union, under the name Epidyolex, it is approved as an add-on treatment with clobazam for LGS and DS in patients two years and older, and for TSC-associated seizures as well. Both the FDA and EMA have granted Orphan Drug Designation (ODD) for EPIDIOLEX/EPIDYOLEX for these conditions. EPIDIOLEX/EPIDYOLEX net product sales rose by 15% to USD 972.4 million in 2024 and by 14% to USD 275.0 million in the fourth quarter of 2024, compared to the corresponding periods in 2023. Learn more about EPIDIOLEX/EPIDYOLEX projected market size for DEE @ EPIDIOLEX Market Potential Developmental and epileptic encephalopathies (DEE) encompass a group of severe neurological conditions marked by developmental delays and persistent epilepsy. These disorders typically present early in life and are linked to significant cognitive deficits. According to DelveInsight's analysis, there were approximately 287K diagnosed prevalent cases of DEE across the 7MM in 2024. This number is projected to increase due to the rise in neurological disorders, including epilepsy, as well as environmental and maternal health factors contributing to a higher DEE prevalence throughout the forecast period (2025−2034). The US FDA has approved a range of medications for conditions like LGS, Dravet Syndrome, and CDKL5 Deficiency Disorder, including various drug classes such as sodium channel modulators, GABA receptor modulators, calcium channel blockers, receptor blockers, and others. Some of the available anti-epileptic drugs (AEDs) include FINTEPLA, EPIDIOLEX, TOPAMAX, BANZEL, LAMICTAL, FELBATOL, ONFI, KLONOPIN, DIACOMIT, SABRIL, and more. In 2024, the total market size for DEE in the 7MM was around USD 2.3 billion, and this figure is expected to grow by 2034, driven by wider adoption of approved therapies due to label expansions and the introduction of emerging treatments. Discover more about the DEE market in detail @ Developmental and Epileptic Encephalopathy Market Report Emerging Competitors of EPIDIOLEX Some of the drugs in the pipeline include EPX-100 (Harmony Biosciences), Bexicaserin (Lundbeck), Zorevunersen (Stoke Therapeutics/Biogen), Relutrigine (Praxis Precision Medicines), and others. In August 2024, the FDA removed a partial clinical hold as the company advances toward a Phase III registrational study of zorevunersen (STK-001) in children and adolescents with Dravet syndrome. In July 2024, Longboard Pharmaceuticals announced that the FDA had granted Breakthrough Therapy designation for its investigational drug bexicaserin for the treatment of seizures associated with DEEs for patients 2 years of age or older. To know more about the number of competing drugs in development, visit @ EPIDIOLEX Alternatives Key Milestones of EPIDIOLEX In August 2024, Jazz Pharmaceuticals reported top-line results from a Phase 3 open-label, single-arm study conducted in Japan, assessing the safety and effectiveness of its cannabidiol oral solution (marketed globally as EPIDIOLEX/EPIDYOLEX) as an add-on therapy for seizures linked to Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), or tuberous sclerosis complex (TSC). While the trial did not achieve its primary efficacy goal—defined as a pre-specified percentage reduction in seizure frequency during the up-to-16-week treatment period compared to baseline in Japanese pediatric patients—numerical improvements were noted in both the primary and several secondary measures. The study did not identify any new safety concerns. In May 2021, Jazz Pharmaceuticals acquired EPIDIOLEX as part of the acquisition of GW Pharmaceuticals plc, or GW, which expanded its growing neuroscience business with a global, high-growth childhood-onset epilepsy franchise. In April 2021, EPIDYOLEX was approved for adjunctive therapy of seizures associated with TSC for patients 2 years of age and older in the EU. In July 2020, EPIDYOLEX was approved for the treatment of seizures associated with TSC in patients one year of age and older. FDA also approved the expansion of all existing indications, LGS and DS, to patients one year of age and older. In September 2019, the European Commission approved EPIDYOLEX for use as adjunctive therapy of seizures associated with LGS or DS, in conjunction with clobazam, for patients two years of age and older. In June 2018, EPIDIOLEX was approved in the US for the treatment of seizures associated with two rare and severe forms of epilepsy, LGS and DS, in patients two years of age and older. EPIDIOLEX Launch Status EPIDIOLEX was launched on November 1, 2018, in the US market after FDA approval for the treatment of seizures associated with LGS or Dravet syndrome in patients two years of age and older. EPIDYOLEX was launched in 2019 in Germany and the UK market for use as adjunctive therapy for seizures associated with LGS or Dravet syndrome, in conjunction with clobazam, for patients two years of age and older (GW Pharmaceuticals, 2019b). In 2021, EPIDYOLEX was launched in Spain. In the first quarter of 2022, the company launched EPIDYOLEX for LGS, Dravet syndrome, and TSC in Ireland, for TSC in Scotland and Wales. In the third quarter of 2022, the company launched EPIDYOLEX for TSC in Italy and Switzerland. In the fourth quarter of 2022, the company successfully completed the pricing and reimbursement process and commercial launch of EPIDYOLEX in France. Discover how EPIDIOLEX/EPIDYOLEX is shaping the DEE treatment landscape @ EPIDIOLEX CBD EPIDIOLEX Market Dynamics EPIDIOLEX, the first FDA-approved cannabidiol (CBD)-based medication for the treatment of rare forms of epilepsy, has had a significant impact on the pharmaceutical market since its approval in 2018. The drug is primarily used to treat seizures associated with Dravet syndrome and Lennox-Gastaut syndrome, two rare and severe forms of epilepsy. The market dynamic for EPIDIOLEX is shaped by several factors, including increasing awareness of its therapeutic potential, the expanding medical cannabis industry, and the growing demand for alternative treatments to traditional anti-epileptic drugs. One of the main drivers of the EPIDIOLEX market is the rising acceptance of CBD-based therapies. As medical cannabis becomes more mainstream and research into its medicinal properties continues to grow, patients and healthcare providers are increasingly turning to EPIDIOLEX as a treatment option. The growing body of clinical evidence supporting its effectiveness and safety has reinforced this trend. Additionally, as the stigma around cannabis-derived medications continues to fade, it opens up more opportunities for EPIDIOLEX in both pediatric and adult patient populations. However, the market for EPIDIOLEX is not without its challenges. High treatment costs and insurance coverage issues can limit accessibility for some patients, especially in markets outside the United States. Despite its clinical efficacy, the price point for EPIDIOLEX remains a point of contention, as it may not be affordable for all families, especially when compared to other conventional anti-epileptic drugs. Furthermore, competition from other cannabinoid-based therapies, as well as new developments in the broader epilepsy drug market, could impact the drug's market share over time. Looking ahead, the market dynamics for EPIDIOLEX will likely continue to evolve as the global regulatory landscape changes and new clinical trials further establish its benefits in other neurological conditions. With increasing research into CBD's potential applications, there may be opportunities for EPIDIOLEX to expand its indications, providing a solid foundation for its continued growth. However, market growth will also depend on the ability to address pricing concerns, improve insurance coverage, and navigate potential competitive pressures from both traditional and emerging therapies.
