    Results presented at ARVO annual meeting confirm earlier preclinical findings and support the Company's work to discover and develop the first potential disease modifying approach for the treatment of ADOA –

    ADOA is the most common inherited optic nerve disorder –

    Stoke Therapeutics, Inc. (NASDAQ:STOK), a biotechnology company dedicated to addressing the underlying cause of severe diseases by up-regulating protein expression with RNA-based medicines, today announced new preclinical data demonstrating in-vitro protein upregulation and improved mitochondrial function in OPA1 protein-deficient fibroblasts derived from patients with ADOA. OPA1 protein deficiency is the primary cause of ADOA and reduced OPA1 levels are associated with impaired mitochondrial function. The data will be presented today at The Association for Research in Vision and Ophthalmology (ARVO) 2021 Annual Meeting and at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting on Tuesday, May 11, 2021 from 8:00 AM – 10:00 AM Eastern.

    "These findings are important because they offer the first evidence from patient cells that our TANGO approach can address the underlying cause of ADOA by upregulating OPA1 protein production and increasing mitochondrial function," said Edward M. Kaye, M.D., Chief Executive Officer of Stoke Therapeutics. "ADOA represents a strong fit for Stoke's science and our strategy: targeting severe genetic diseases that are caused by protein deficiencies and that have limited, if any treatment options. A disease-modifying approach would represent a significant advancement in the treatment of this disease."

    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. 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.

    "By demonstrating an improvement in the mitochondrial function of patient cells across different OPA1 mutations, the data suggest that ASO mediated increase in OPA1 could be sufficient to slow or reduce disease progression in a mutation-independent manner," said Gene Liau, Ph.D., Chief Scientific Officer of Stoke Therapeutics.

    The data presented today provide in-vitro proof-of-concept for TANGO ASOs in ADOA patient fibroblasts. Highlights from today's presentation include new data that demonstrate ADOA patient fibroblast cell lines treated with TANGO ASOs exhibit:

    • Reduced non-productive exon inclusion and increased total OPA1 mRNA expression in three patient fibroblast cell lines with different mutations;
    • Increased expression of multiple OPA1 protein isoforms by ~35% to 47%; and
    • A dose-dependent improvement in mitochondrial bioenergetics.

    Details of today's presentation are as follows:

    Presentation Title: Antisense oligonucleotide mediated increase in OPA1 improves mitochondrial function in fibroblasts derived from patients with autosomal dominant optic atrophy (ADOA)

    Session Date & Time: Tuesday, May 4, 2021; 2:15 p.m. – 3:45 p.m. E.T.

    Session Title: Gene therapy in ocular diseases

    Presenter: Aditya Venkatesh, Ph.D., Senior Scientist, Stoke Therapeutics

    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. Symptoms typically begin between the ages of 4 and 6 years old, affecting males and females equally. The severity of the condition by adolescence reflects the overall level of visual function to be expected throughout most of the individual's adult life. Roughly half of people with ADOA fail driving standards and up to 46% are registered as legally blind. ADOA is considered a haploinsufficiency disease, as most people living with ADOA have genetic mutations in the OPA1 gene that result in only half the necessary OPA1 protein being produced. 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. 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.

    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, so the body does not function normally. 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 target genes produce more protein. TANGO aims to restore missing proteins by increasing – or stoking – protein output from healthy genes, thus compensating for the non-functioning copy of the gene.

    About Stoke Therapeutics

    Stoke Therapeutics (NASDAQ:STOK), is a biotechnology company dedicated to addressing the underlying cause of severe diseases by up-regulating protein expression with RNA-based medicines. Using the company's proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) approach Stoke is developing antisense oligonucleotides (ASOs) to selectively restore protein levels. The company'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. The company is pursuing treatment for a second haploinsufficient disease, 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 the company's belief in the broad potential for its proprietary approach.

    – STK-001 has the potential to be the first disease-modifying therapy to address the root cause of Dravet syndrome, a severe and progressive genetic epilepsy –

    Stoke Therapeutics, Inc. (NASDAQ:STOK), a biotechnology company dedicated to addressing the underlying cause of severe diseases by up-regulating protein expression with RNA-based medicines, today announced the authorization of its Clinical Trial Application (CTA) by the United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a Phase 1/2a study (ADMIRAL) of STK-001 for the treatment of Dravet syndrome.

    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, a severe and progressive genetic epilepsy characterized by frequent, prolonged and refractory seizures that usually begin within the first year of life. Dravet syndrome is classified as a developmental and epileptic encephalopathy resulting in developmental delay and cognitive impairment, in addition to seizure activity, that arise from the genetic mutation that causes the disease.

    "We are making excellent progress with our ongoing studies of STK-001 in the U.S. The high level of interest from the Dravet community underscores the urgent need for new treatment options that go beyond seizure control," said Edward M. Kaye, M.D., Chief Executive Officer of Stoke Therapeutics. "The ADMIRAL study complements our U.S.-based MONARCH study, enabling the evaluation of higher dose levels of STK-001 and representing an initial step in the expansion of our global clinical development efforts. Together, we anticipate that these studies will generate a comprehensive set of data that will inform our future development plans. We look forward to working with the U.K. Dravet community – patients, families and healthcare providers – to add to our understanding of the potential for STK-001 to be the first disease-modifying therapy for Dravet syndrome."

    ADMIRAL is an open-label, multi-center, Phase 1/2a study designed to assess the safety and tolerability of multiple doses of up to 70mg of STK-001, as well as to characterize human pharmacokinetics. Secondary endpoints include change in seizure frequency and quality of life measures. The study is expected to enroll approximately 22 children and adolescents with Dravet syndrome across multiple clinical sites in the United Kingdom. Patient enrollment and dosing are expected to start in the second half of 2021.

    "Current treatments for Dravet syndrome help us manage seizures, but some of the most devastating effects of the disease such as developmental and intellectual disabilities are not addressed by current therapies," said Professor Helen Cross, Honorary Consultant in Paediatric Neurology at Great Ormond Street Hospital for Children NHS Foundation Trust. "There is great hope that a new approach, such as STK-001, that targets the root cause of the disease, may address the seizures as well as the myriad of devastating comorbidities that have impacts on patients and their families. I'm pleased to be helping lead the effort to bridge the treatment gap by conducting the first study of STK-001 in the U.K. as the lead investigator for the ADMIRAL study."

    MONARCH Phase 1/2a Clinical Trial is Ongoing in the United States

    Enrollment of children and adolescents in the first two single ascending dose (SAD) cohorts (10mg and 20mg) is complete and enrollment and dosing in the third (30mg) SAD cohort is underway. Dosing above 30mg in this study remains on partial clinical hold with the U.S. Food and Drug Administration (FDA). Preliminary safety and pharmacokinetic data from the SAD portion of the MONARCH study are expected in the second half of 2021.

    In addition, enrollment and dosing in the multiple ascending dose (MAD) portion of the MONARCH study is underway at the 20mg dose level. Patients who participated in the MONARCH study 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. Enrollment and dosing in SWALLOWTAIL are underway.

    About STK-001

    STK-001 is an investigational new medicine for the treatment of Dravet syndrome and is being evaluated in a Phase 1/2a clinical trial. 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 up-regulate 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 as a potential new treatment for Dravet syndrome.

    About the Phase 1/2a MONARCH Clinical 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 characterize human pharmacokinetics. A secondary objective is to assess the effect as an adjunctive antiepileptic treatment with respect to the percentage change from baseline in convulsive seizure frequency over a 12-week treatment period. Stoke also intends to measure non-seizure aspects of the disease, such as quality of life, as secondary endpoints. Enrollment and dosing are ongoing in MONARCH and Stoke plans to enroll approximately 48 patients in the study across 20 sites in the United States.

    Additional information about the MONARCH study can be found at https://www.monarchstudy.com/.

    Patients who participated in the MONARCH study 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. Enrollment and dosing in SWALLOWTAIL are underway.

    About the 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 characterize human pharmacokinetics. 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 over a 24-week treatment period. Stoke also intends to measure non-seizure aspects of the disease, such as overall clinical status and quality of life, as secondary endpoints. Stoke plans to enroll approximately 22 patients in the study across multiple sites in the United Kingdom.

    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 severe intellectual disabilities, severe developmental disabilities, motor impairment, speech impairment, autism, behavioral difficulties and sleep abnormalities. 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. Approximately 85% of those diagnosed with Dravet syndrome have a mutation of the SCN1A gene. Dravet syndrome affects approximately 35,000 people in the United States, Canada, Japan, Germany, France and the United Kingdom, and it is not concentrated in a particular geographic area or ethnic group.

    Stoke Therapeutics, Inc. (NASDAQ:STOK), a biotechnology company dedicated to addressing the underlying cause of severe diseases by up-regulating protein expression with RNA-based medicines, today reported financial results for the full year ended December 31, 2020 and provided business updates.

    "During the last year, the power and potential of RNA medicines became clear to the world. Simultaneously, the Stoke team advanced our efforts to discover and develop RNA-based medicines that aim to address the underlying cause of severe genetic diseases by selectively boosting protein production," said Edward M. Kaye, M.D., Chief Executive Officer of Stoke Therapeutics. "Our Phase 1/2a MONARCH study in children and adolescents with Dravet syndrome is well underway and patients are now being treated with STK-001 in both the single and multiple ascending dose portions of this study. We also recently initiated an open-label extension study called SWALLOWTAIL that will provide ongoing treatment with STK-001 for patients who complete MONARCH. We expect that SWALLOWTAIL and the MAD portion of MONARCH will provide important information on the potential effects of repeat doses of STK-001."

    Dr. Kaye continued, "Looking ahead to 2021, we are on track to report preliminary safety and PK data from the SAD portion of MONARCH in the second half of the year. Our pipeline continues to advance as well. Lead optimization efforts are underway to identify a clinical candidate for OPA1 protein deficiency, the primary cause of autosomal dominant optic atrophy, and our research team is interrogating several targets of interest with the goal of demonstrating in vivo proof of mechanism and safety for another program by year end."

    Fourth Quarter 2020 Business Highlights and Recent Developments

    • The Company announced today continued clinical progress with the Phase 1/2a MONARCH study of children and adolescents with Dravet syndrome. Enrollment of patients in the first two single ascending dose (SAD) cohorts (10mg and 20mg) is now complete. Enrollment and dosing in the third (30mg) SAD cohort is underway.
    • Also announced today was the start of the multiple ascending dose (MAD) portion of the MONARCH study with the first patient enrolled and dosed in February at the 20mg dose level.
    • In January 2021, the Company began dosing patients in SWALLOWTAIL, an open label extension (OLE) 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 MONARCH study.
    • In January 2021, the Company announced completion of enrollment (n=36) in the BUTTERFLY observational study of children and adolescents ages 2 to 18 years old with Dravet syndrome. The study is ongoing.
    • In December 2020, the Company presented four abstracts related to its work in Dravet syndrome at the American Epilepsy Society (AES) 2020 Virtual Annual Meeting. Highlights from these presentations include baseline data from children and adolescents with Dravet syndrome enrolled in the BUTTERFLY observational study, which provide initial support of use of standard measures of cognition (BSID-III and WPPSI-IV) in evaluating non-seizure comorbidities in people with Dravet syndrome and new preclinical data demonstrating the ability of TANGO ASOs to help restore normal function of nerve cells, which correlate to reductions in seizure frequency and extended survival. In addition, data showed that a no-cost epilepsy genetic testing program co-sponsored by Stoke can diagnose genetic epilepsies earlier.
    • On November 24, 2020, the Company closed an underwritten public offering of 2,875,000 shares of its common stock at a price to the public of $39.00 per share. The net proceeds from the offering were approximately $104.9 million, after deducting underwriting discounts, commissions and offering expenses.

    Upcoming Anticipated Milestones

    • Preliminary safety and pharmacokinetic data from the SAD portion of the Phase 1/2a MONARCH study are expected in the second half of 2021.
    • In the second half of 2021, the Company plans to initiate natural history data collection of people living with autosomal dominant optic atrophy (ADOA) to better understand the natural progression of this disease, which is the most common inherited optic nerve disorder. The Company hopes to use the data to support future clinical development plans for the Company's OPA1 program.
    • Lead optimization is underway to potentially identify a clinical candidate for OPA1, the Company's next preclinical target, by the end of 2021.
    • Also, by the end of 2021, the Company expects to demonstrate in vivo proof of mechanism and safety for a third TANGO ASO program.

    Year End 2020 Financial Results

    • Net loss for the year ended December 31, 2020 was $52.3 million, or $1.56 per share compared to $32.3 million or $1.80 per share for the same period in 2019.
    • Research and development expenses for the year ended December 31, 2020 were $32.2 million, compared to $23.8 million for the same period in 2019.
    • General and administrative expenses for the year ended December 31, 2020 were $20.8 million, compared to $11.9 million for the same period in 2019.
    • The increase in expenses for the 2020 periods over the same periods in 2019 primarily relate to increases in costs associated with personnel, third party contracts, consulting, facilities and others associated with development activities for STK-001, research on additional therapeutics and growing a public corporation.
    • As of December 31, 2020, Stoke had approximately $287.5 million in cash, cash equivalents and restricted cash, which is anticipated to fund operations into 2024.

    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, so the body does not function normally. 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 target genes produce more protein. TANGO aims to restore missing proteins by increasing – or stoking – protein output from healthy genes, thus compensating for the non-functioning copy of the gene.

    About STK-001

    STK-001 is an investigational new medicine for the treatment of Dravet syndrome currently being evaluated in a Phase 1/2a clinical trial. 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 as a potential new treatment for Dravet syndrome.

    About Phase 1/2a Clinical Study (MONARCH)

    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 pathogenic 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 characterize human pharmacokinetics. 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 over a 12-week treatment period. Stoke also intends to measure non-seizure aspects of the disease, such as quality of life, as secondary endpoints. Enrollment and dosing are ongoing in MONARCH and Stoke plans to enroll approximately 48 patients in the study across 20 sites in the United States.

    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 severe intellectual disabilities, severe developmental disabilities, motor impairment, speech impairment, autism, behavioral difficulties and sleep abnormalities. 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. Dravet syndrome affects approximately 35,000 people in the United States, Canada, Japan, Germany, France and the United Kingdom, and it is not concentrated in a particular geographic area or ethnic group.

    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. Symptoms typically begin between the ages of 4 and 6 years old, affecting males and females equally. The severity of the condition by adolescence reflects the overall level of visual function to be expected throughout most of the individual's adult life. Roughly half of people with ADOA fail driving standards and up to 46% are registered as legally blind. ADOA is considered a haploinsufficiency, as most people living with ADOA have genetic mutations in the OPA1 gene that result in only half the necessary OPA1 protein being produced. More than 400 OPA1 mutations have been reported in people diagnosed with ADOA. Currently there is no approved treatment for people living with ADOA.

    About Stoke Therapeutics

    Stoke Therapeutics (NASDAQ:STOK), is a biotechnology company dedicated to addressing the underlying cause of severe diseases by up-regulating protein expression with RNA-based medicines. Using the company's proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) approach Stoke is developing antisense oligonucleotides (ASOs) to selectively restore protein levels. The company'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. The company is pursuing treatment for a second haploinsufficient disease, 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 the company's belief in the broad potential for its proprietary approach. Stoke is headquartered in Bedford, Massachusetts with offices in Cambridge, Massachusetts.
