Stoke Therapeutics Enrolls First Patient in a Natural History Study of People Living with Autosomal Dominant Optic Atrophy (ADOA)
– ADOA is primarily caused by mutations in the OPA1 gene that result in progressive and irreversible vision loss in both eyes starting in the first decade of life –
– The FALCON study is designed to evaluate disease progression and its effects on patients –
– Data will support clinical development plans for STK-002, a potential new medicine that targets the underlying cause of ADOA –
Most cases of ADOA are caused by mutations in one allele of the OPA1 gene, which result in half of the normal OPA1 protein production. FALCON is a two-year prospective natural history study in patients who have a confirmed diagnosis of ADOA that is caused by an OPA1 mutation. The study is designed to evaluate the rate of change in structural and functional ophthalmic assessments. Data from the FALCON study will support the clinical development of STK-002, Stoke’s proprietary antisense oligonucleotide (ASO) in preclinical development for the treatment of ADOA.
“ADOA is a severe and progressive disease that, for many patients, leads to legal blindness,” said
“Understanding what causes ADOA is helping diagnose the disease earlier and is, for the first time, giving us the opportunity to develop medicines that may be able to slow or even stop vision loss in these patients,” said
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
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
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.
