Stoke Therapeutics Reports Third Quarter Financial Results and Provides Business Updates

– Company plans to provide seizure as well as cognition and behavior data from all patients treated with initial 70mg doses followed by 45mg maintenance dosing in studies of zorevunersen by year-end –

– Discussions with FDA and global regulatory agencies related to a single global Phase 3 study of zorevunersen continue to progress; Company to provide an update by year-end –

– As of September 30, 2024, Company had $269.2 million in cash, cash equivalents, and marketable securities –

BEDFORD, Mass., November 5, 2024 – Stoke Therapeutics, Inc. (Nasdaq: STOK), a biotechnology company dedicated to restoring protein expression by harnessing the body’s potential with RNA medicine, today reported financial results for the third quarter of 2024 and provided business updates including those related to zorevunersen, the Company’s proprietary antisense oligonucleotide (ASO) which is in development by Stoke as the first potential medicine to address the genetic cause of Dravet syndrome.

“We are headed into a busy year-end as we prepare to share new data which is representative of our proposed Phase 3 dosing regimen and complete our regulatory discussions toward alignment on that study design,” said Edward M. Kaye, M.D., Chief Executive Officer of Stoke Therapeutics. “Key to our regulatory discussions are the assessments of behavior and cognition in patients with Dravet syndrome. In our studies of zorevunersen, we have demonstrated substantial and sustained effects across multiple measures of disease, starting within the first year of treatment. These data give us confidence in our Phase 3 planning and the potential for zorevunersen to go beyond seizure management by addressing the root cause of the disease.”

The Company announced today that it has submitted abstracts for presentation at the American Epilepsy Society meeting taking place December 6-10, in Los Angeles, California. Included among these planned presentations are new data from all patients treated in the clinical studies with initial 70mg doses followed by 45mg maintenance dosing in studies of zorevunersen. A Phase 3 regimen of two or three loading doses of 70mg followed by maintenance doses of 45mg is currently under discussion with global regulatory agencies. As the Company continues to focus on zorevunersen as its lead program, it will delay the start of the Phase 1 study of STK-002, its clinical candidate for the treatment of autosomal dominant optic atrophy (ADOA).

Recent Program Highlights and Upcoming Milestones

  • In August, the Company announced that the U.S. Food and Drug Administration (FDA) has removed the Partial Clinical Hold on zorevunersen.

  • In September, the Company shared data from the Phase 1/2a and open-label extension (OLE) studies of zorevunersen in children and adolescents with Dravet syndrome at the 15th European Epilepsy Congress (EEC).

  • Company management will present at the Jefferies London Healthcare Conference on Wednesday, November 20, at 6:30am EST (11:30am GMT). A live webcast of the presentation will be available on the Investors & News section of Stoke’s website.

  • The Company expects to present data at the American Epilepsy Society (AES) 2024 Annual Meeting, pending acceptance of the abstracts.

  • The Company plans to provide an update on Phase 3 registrational plans for zorevunersen by year-end.

Third Quarter 2024 Financial Results

  • Net loss for the three months ended September 30, 2024 was $26.4 million, or $0.47 per share, compared to $24.5 million, or $0.55 per share, for the same period in 2023.
  • Research and development expenses for the three months ended September 30, 2024 were $22.2 million, compared to $20.3 million for the same period in 2023.

  • Research and development expenses for the nine months ended September 30, 2024 were $65.7million, compared to $60.5 million for the same period in 2023.

About Dravet Syndrome

Dravet syndrome is a severe and progressive genetic epilepsy characterized by frequent, prolonged and refractory seizures, beginning within the first year of life. Dravet syndrome is difficult to treat and has a poor long-term prognosis. Complications of the disease often

contribute to a poor quality of life for patients and their caregivers. The effects of the disease go beyond seizures and 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. The disease is classified as a developmental and epileptic encephalopathy due to the developmental delays and cognitive impairment associated with the disease. Compared with the general epilepsy population, people living with Dravet syndrome have a higher risk of sudden unexpected death in epilepsy, or SUDEP. There are no approved disease-modifying therapies for people living with Dravet syndrome. One out of 16,000 babies are born with Dravet syndrome, which is not concentrated in a particular geographic area or ethnic group.

About Zorevunersen (STK-001)

Zorevunersen is an investigational new medicine for the treatment of Dravet syndrome currently being evaluated in ongoing clinical trials. Stoke believes that zorevunersen, a proprietary antisense oligonucleotide (ASO), has the potential to be the first disease-modifying therapy to address the genetic cause of Dravet syndrome. Zorevunersen is designed to upregulate Nav1.1 protein expression by leveraging the non-mutant (wild-type) copy of the SCN1A gene to restore physiological Nav1.1 levels, thereby reducing both occurrence of seizures and significant non-seizure comorbidities. Zorevunersen has been granted orphan drug designation by the FDA and the EMA, and rare pediatric disease designation by the FDA as a potential new treatment for Dravet syndrome.

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 protein levels. Stoke’s first compound, zorevunersen (STK-001), is in clinical testing for the treatment of Dravet syndrome, a severe and progressive genetic epilepsy. Dravet syndrome is one of many diseases caused by a haploinsufficiency, in which a loss of ~50% of normal protein levels leads to disease. Stoke is pursuing the development of STK-002 for the treatment of autosomal dominant optic atrophy (ADOA), the most common inherited optic nerve disorder. Stoke’s initial focus is haploinsufficiencies and diseases of the central nervous system and the eye, although proof of concept has been demonstrated in other organs, tissues, and systems, supporting its belief in the broad potential for its proprietary approach. Stoke is headquartered in Bedford, Massachusetts with offices in Cambridge, Massachusetts. For more information, visit https://www.stoketherapeutics.com/.
