– Analysis will also include seizure frequency data, including preliminary 3-month results from a subset of patients who received three doses of STK-001 (30mg or 45mg) –
– Company was granted FDA orphan drug designation for STK-002, an investigational new treatment for Autosomal Dominant Optic Atrophy (ADOA) –
– As of June 30, 2022, Company had $276.2 million in cash, cash equivalents, marketable securities, and restricted cash, anticipated to fund operations into 2025 –
BEDFORD, Mass., August 8, 2022 – Stoke Therapeutics, Inc. (Nasdaq: STOK), a biotechnology company dedicated to addressing the underlying cause of severe diseases by upregulating protein expression with RNA-based medicines, today reported financial results for the second quarter of 2022 and provided business updates.
“The Stoke team continues to execute and we look forward to our next readout of data from our ongoing clinical studies of STK-001 in children and adolescents with Dravet syndrome,” said Edward M. Kaye, M.D., Chief Executive Officer of Stoke Therapeutics. “These initial studies of STK-001 are designed primarily to evaluate safety, but we are also looking to these data to guide our understanding of the optimal dose level and administration frequency for this potential new medicine.”
“Dravet syndrome is characterized by frequent, prolonged and intractable seizures,” continued Kaye. “Despite being treated with multiple anti-seizure medicines, most patients continue to experience a high seizure burden. As part of our readout in the fourth quarter, we look forward to seeing the first seizure frequency data from the group of patients in our MONARCH and ADMIRAL studies who were treated with multiple doses of 30mg or 45mg of STK-001 on top of their existing anti-seizure regimen.”
Second Quarter 2022 Business Highlights and Recent Developments
|
|
• |
Today, the Company provided updates from the ongoing clinical studies of STK-001. In the U.S., dosing is ongoing in the 45mg multiple dose cohort of MONARCH. In the U.K., dosing is complete in the 45mg multiple dose cohort, and the first patients have now been dosed in the 70mg multiple dose cohort of ADMIRAL. |
|
|
• |
Dosing is ongoing in SWALLOWTAIL, an open-label extension study of STK-001. Patients in this study are now eligible to receive 45mg doses of STK-001. |
|
|
• |
In May 2022, the Company began dosing patients in LONGWING, an open-label extension study designed to evaluate the long-term safety and tolerability of repeat doses of STK-001 in patients who participated in the Phase 1/2a ADMIRAL study. |
|
|
• |
In May 2022, the Company presented new preclinical data for STK-002 that demonstrated in-vivo, dose-related target engagement and OPA1 protein upregulation with sustained effect in non-human primate (NHP) retinal tissue following intravitreal (IVT) administration of STK-002. A dose-related increase in OPA1 protein was also detected in retinal ganglion cells (RGCs) of NHPs treated with STK-002. |
|
|
• |
In July 2022, the U.S. Food and Drug Administration (FDA) granted orphan drug designation to STK-002 for the potential treatment of patients with ADOA. |
Upcoming Anticipated Milestones
|
|
• |
In the fourth quarter, the Company plans to report preliminary clinical data from approximately 40 patients in the ongoing MONARCH, ADMIRAL and SWALLOWTAIL studies of STK-001 in children and adolescents with Dravet syndrome. The focus of the interim analysis will be on safety, pharmacokinetic (PK), and cerebrospinal fluid (CSF) drug exposure data from these studies. In addition, the Company plans to report seizure frequency data, including preliminary results from up to 24 patients in the MONARCH and ADMIRAL studies who received three doses of STK-001 (up to 18 patients at 30mg and up to 6 patients at 45mg) and were followed for three months. |
|
|
• |
In 2023, the Company expects to share additional data from patients who were treated in the 45mg and the 70mg dose cohorts in the ongoing clinical studies of STK-001. |
|
|
• |
In the second half of 2022, the Company expects to begin enrollment in a prospective natural history study (FALCON) of people living with ADOA. |

About TANGO
TANGO (Targeted Augmentation of Nuclear Gene Output) is Stoke’s proprietary research platform. Stoke’s initial application for this technology are diseases in which one copy of a gene functions normally and the other is mutated, also called haploinsufficiencies. In these cases, the mutated gene does not produce its share of protein, resulting in disease. Using the TANGO approach and a deep understanding of RNA science, Stoke researchers design antisense oligonucleotides (ASOs) that bind to pre-mRNA and help the functional (or wild-type) genes produce more protein. TANGO aims to restore missing proteins by increasing – or stoking – protein output from healthy genes, thus compensating for the mutant copy of the gene.
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 STK-001
STK-001 is an investigational new medicine for the treatment of Dravet syndrome currently being evaluated in ongoing clinical trials. Stoke believes that STK-001, a proprietary antisense oligonucleotide (ASO), has the potential to be the first disease-modifying therapy to address the genetic cause of Dravet syndrome. STK-001 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. Stoke has generated preclinical data demonstrating proof-of-mechanism and proof-of-concept
for STK-001. STK-001 has been granted orphan drug designation by the FDA and the EMA as a potential new treatment for Dravet syndrome.
About Phase 1/2a MONARCH Study (United States)
The MONARCH study is a Phase 1/2a open-label study of children and adolescents ages 2 to 18 who have an established diagnosis of Dravet syndrome and have evidence of a genetic mutation in the SCN1A gene. The primary objectives for the study are to assess the safety and tolerability of STK-001, as well as to determine the pharmacokinetics in plasma and exposure in cerebrospinal fluid. A secondary objective is to assess the efficacy as an adjunctive antiepileptic treatment with respect to the percentage change from baseline in convulsive seizure frequency. Stoke also intends to measure non-seizure aspects of the disease, such as quality of life, as secondary endpoints. Additional information about the MONARCH study can be found at https://www.monarchstudy.com/.
Patients who participated in the MONARCH study and meet study entry criteria are eligible to continue treatment in SWALLOWTAIL, an open-label extension (OLE) study designed to evaluate the long-term safety and tolerability of repeat doses of STK-001. We expect that SWALLOWTAIL will also provide valuable information on the preliminary effects of STK-001 on seizures along with non-seizure aspects of the disease, such as quality of life and cognition.
Enrollment and dosing in SWALLOWTAIL are underway.
About Phase 1/2a ADMIRAL Study (United Kingdom)
The ADMIRAL study is a Phase 1/2a open-label study of children and adolescents ages 2 to <18 who have an established diagnosis of Dravet syndrome and have evidence of a genetic mutation in the SCN1A gene. The primary objectives for the study are to assess the safety and tolerability of multiple doses of STK-001, as well as to determine the pharmacokinetics in plasma and exposure in cerebrospinal fluid. A secondary objective is to assess the effect of multiple doses of STK-001 as an adjunctive antiepileptic treatment with respect to the percentage change from baseline in convulsive seizure frequency. Stoke also intends to measure non-seizure aspects of the disease, such as overall clinical status and quality of life, as secondary endpoints. Additional information about the ADMIRAL study can be found at https://www.admiralstudy.com.
Patients who participated in the ADMIRAL study and meet study entry criteria are eligible to continue treatment in LONGWING, an open-label extension (OLE) study designed to evaluate the long-term safety and tolerability of repeat doses of STK-001. We expect that LONGWING will also provide valuable information on the preliminary effects of STK-001 on seizures along with non-seizure aspects of the disease, such as quality of life and cognition.
Enrollment and dosing in LONGWING are underway.
About Autosomal Dominant Optic Atrophy (ADOA)
Autosomal dominant optic atrophy (ADOA) is the most common inherited optic nerve disorder. It is a rare disease that causes progressive and irreversible vision loss in both eyes starting in the first decade of life. Severity can vary and the rate of vision loss can be difficult to predict. Roughly half of people with ADOA fail driving standards and up to 46% are registered as legally blind.
More than 400 OPA1 mutations have been reported in people diagnosed with ADOA. Currently there is no approved treatment for people living with ADOA. ADOA affects approximately one in 30,000 people globally with a higher incidence in Denmark of one in 10,000 due to a founder effect.
About STK-002
STK-002 is a proprietary antisense oligonucleotide (ASO) in preclinical development for the treatment of Autosomal Dominant Optic Atrophy (ADOA). Approximately 80% of individuals with ADOA experience symptoms before age 10, typically beginning between the ages of 4 and 6. Stoke believes that STK-002 has the potential to be the first disease-modifying therapy for people living with ADOA. An estimated 65% to 90% of cases are caused by mutations in the OPA1 gene, most of which lead to a haploinsufficiency resulting in 50% OPA1 protein expression and disease manifestation. STK-002 is designed to upregulate OPA1 protein expression by leveraging the non-mutant (wild-type) copy of the OPA1 gene to restore OPA1 protein expression with the aim to stop or slow vision loss in patients with ADOA. Stoke has generated preclinical data demonstrating proof-of-mechanism and proof-of-concept for STK-002. STK-002 has been granted orphan drug designation by the FDA as a potential new treatment for ADOA.
About the FALCON Study
FALCON is a multicenter, prospective natural history study of people ages 8 to 60 who have an established clinical diagnosis of ADOA that is caused by a heterozygous OPA1 gene variant. No investigational medications or other treatments will be provided. The study is expected to enroll approximately 45 patients across 10 sites in the U.S., U.K., Italy and Denmark. Patients will undergo assessments at 6 months, 12 months, 18 months, and 24 months. There will be no additional follow-up period. For more information about enrolling in the study, please email Falconstudy@medpace.com.
About Stoke Therapeutics
Stoke Therapeutics (Nasdaq: STOK), is a biotechnology company dedicated to addressing the underlying cause of severe diseases by upregulating protein expression with RNA-based medicines. 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, 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/ or follow Stoke on Twitter at @StokeTx.
