Financial Analyst

Stoke Therapeutics' Q2 2024 results reveal a mixed financial picture. The company's $282.0 million cash position provides a solid runway for ongoing R&D efforts. However, the net loss of $25.7 million ($0.46 per share) for Q2, while improved from $30.7 million in Q2 2023, still indicates significant cash burn. Revenue recognition of $4.8 million from the Acadia collaboration is positive, but R&D expenses increased to $21.1 million, reflecting ongoing investment in pipeline development. The removal of the FDA's Partial Clinical Hold on zorevunersen is a important regulatory milestone, potentially accelerating the path to market. Investors should monitor the upcoming Phase 3 study design announcement, as it will significantly impact the timeline to potential commercialization.

Biotech Research Analyst

The removal of the FDA's Partial Clinical Hold on zorevunersen is a major positive development for Stoke Therapeutics. This clears a significant regulatory hurdle for their lead candidate in Dravet syndrome, a rare and severe form of epilepsy. The company's focus on a single, global Phase 3 registrational study by year-end could streamline the approval process. Additionally, the planned initiation of the OSPREY Phase 1 study for STK-002 in ADOA expands their pipeline into another rare disease area. The "landmark data" mentioned for zorevunersen, showing reductions in seizures and improvements in cognition, suggests strong potential efficacy. However, investors should remain cautious as Phase 3 studies are costly and success is not guaranteed in this complex neurological disorder landscape.

Market Research Analyst

Stoke Therapeutics is positioning itself well in the orphan drug market, particularly in neurological disorders. The company's focus on Dravet syndrome with zorevunersen addresses a high unmet medical need with potential for premium pricing if approved. The expansion into Autosomal Dominant Optic Atrophy (ADOA) with STK-002 demonstrates a strategic broadening of their rare disease portfolio. The collaboration with Acadia Pharmaceuticals, generating $9.0 million in revenue year-to-date, validates their technology platform and provides additional non-dilutive funding. However, the market for rare disease treatments is becoming increasingly competitive. Stoke will need to demonstrate clear differentiation and superior efficacy to capture significant market share. The upcoming regulatory updates and Phase 3 study design will be critical in assessing the company's long-term market potential.

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 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 and the company has received authorization of its CTA from the MHRA.

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/.
