• Apart from the lack of appropriate Stargardt Disease Treatment options, heterogeneity of the disease, diagnostic challenges, and lack of Stargardt Disease Prevalence knowledge are some of the other notable unmet needs associated with Stargardt disease.
• Stargardt disease, also known as Stargardt’s macular dystrophy or Juvenile Macular Degeneration, is a rare genetic eye disease that happens when fatty material builds up on the macula — the small part of the retina needed for sharp, central vision. It is the most prevalent form of recessively inherited macular dystrophy in children, estimated to affect approximately 10 to 12.5 per 100,000 individuals in the United States.
• Stargardt Disease Age of onset is a surrogate marker: The earlier the onset, the more severe the disease course.
• Stargardt disease is characterized by central vision loss, evident in color fundus photography showing macular atrophy with yellow–white lipofuscin flecks at the retinal pigment epithelium level.
• Stargardt disease, an autosomal recessive trait, stems from mutations in the ATP-binding cassette, subfamily a, member 4 (ABCA4) gene, leading to an accelerated accumulation of lipofuscin in the retinal pigment epithelium (RPE).
• Stargardt Disease Diagnosis is primarily based on family history, visual acuity, fundus examination, visual field testing,  fundus autofluorescence (FAF), and optical coherence tomography (OCT)
• In 2023, the United States accounted for the highest number of Stargardt disease cases, which is 43.0% of the Stargardt Disease diagnosed-prevalent cases in the 7MM.
• Among the EU4 and the UK, out of all Stargardt Disease symptoms, the highest cases accounted for reduced vision, followed by Nyctalopia, Photophobia, and others in 2023.
• Presently, there are no standard treatments to prevent or reverse vision loss for Stargardt disease. Patients are offered low-vision aids and are advised to avoid direct sunlight and Vitamin A supplementation to delay the progression of vision loss. In cases where choroidal neovascularization is present, intravitreal anti-VEGF injections are performed.

Stargardt Disease Understanding

Macular Dystrophies (MDs) are a group of inherited retinal disorders that cause significant visual loss, most often as a result of progressive macular atrophy. They are characterized by bilateral, relatively symmetrical macular abnormalities that significantly impair central visual function. Stargardt disease, also known as Stargardt’s macular dystrophy or (Juvenile macular degeneration), stands out as the most prevalent form of macular degeneration in children. Patients grappling with Stargardt disease encounter visual acuity loss, often manifesting in their first or second decades of life, attributed to the atrophy of the retinal pigment epithelium (RPE) and the progressive decline of functional photoreceptors. Stargardt disease invariably results in irreversible decreased vision in nearly all cases.

Stargardt is a genetic disorder. In its typical form (STGD1), it is caused by mutations involving the ABCA4 gene through autosomal recessive homozygous or compound heterozygous transmission. Additionally, autosomal dominant transmission (STGD4) is possible through heterozygous mutations in the PROM1 gene (4p). Stargardt-like macular dystrophies (STGD3), associated with dominant mutations in the ELOVL4 gene (6q14.1), share clinical features with typical Stargardt disease (STGD2). STGD2 was later identified as the same gene as STGD3, leading to the discontinuation of the term STGD2 in 2005.

Further classification is based on the age of disease onset, categorizing STGD1 into three subgroups: early-onset Stargardt Disease Age of Onset = 10 years old), intermediate-onset Stargardt Disease Age of onset between 11 and 45 years old), and late-onset Stargardt Disease Age of Onset > 45 years old). Early-onset STGD1 is the most severe subtype, characterized by fast disease progression, a steep drop in visual acuity in the first years, and the absence of typical STGD1 flecks. Intermediate-onset STGD1 corresponds mostly with the classical STGD1 phenotype, including yellow–white pisciform flecks and slowly evolving central retinal atrophy. Late-onset STGD1 is a milder form with much slower disease progression, often preserving visual acuity for years after onset, resembling age-dependent macular degeneration, and increasing the chance of misdiagnosis.

Stargardt Disease Diagnosis

Diagnostic evaluation of Stargardt disease is based on family history, visual acuity, fundus examination, visual field testing, fluorescein angiography, fundus autofluorescence (FAF), electroretinography (electroretinography market), and optical coherence tomography (OCT). Genetic testing is currently not performed on a routine basis. Visual field testing in Stargardt patients is often normal in early disease stages. Over time, relative central scotomas develop, further progressing to absolute central scotomas variably. Typical Stargardt patients usually preserve their peripheral visual fields. However, in severe cases, with widespread retinal atrophy, visual constriction can occur. Another significant finding is the change in the preferred retinal locus of fixation.

FAF (fundus autofluorescence) imaging provides a fast, non-invasive way to study the health and viability of the RPE. Abnormally increased FAF represents excessive lipofuscin accumulation in the RPE. Inversely, decreased areas of FAF relate to low-level RPE metabolic activity, which normally underlies local atrophy with secondary photoreceptor loss. Therefore, FAF is a perfectly adequate exam to stage and diagnose Stargardt, especially if combined with ultrastructural data derived from OCT.

Stargardt Disease Treatment

Stargardt disease remains an incurable condition. Current therapeutic options include photoprotection and low-vision aids. Pharmacological slow-down of the visual cycle, gene therapy, and other treatment options aim to prevent lipofuscin accumulation and represent prospects of long-term visual rescue. Stargardt Disease patients, already sensitive to light due to impaired ABCA4 function and elevated all-trans-retinal levels, should avoid direct sunlight and Vitamin A supplementation. Ultraviolet-blocking sunglasses are a useful option for Stargardt patients to avoid direct sunlight exposure.

There are currently several ongoing studies and Stargardt Disease clinical trials investigating the potential of various new therapeutic candidates, with gene replacement, stem cell therapy, and pharmacological approaches that may soon bring the scientific and medical community closer to the goal of preventing vision loss in patients with Stargardt disease.

Emerging Stargardt Disease Therapies

• Emixustat: Kubota Pharmaceuticals

Emixustat, developed by Kubota Pharmaceuticals, is an oral drug initially designed to target the dry form of age-related macular degeneration. It functions by slowing the buildup of toxic waste products that contribute to retinal degeneration in various retinal conditions, including Stargardt disease.

The Stargardt Disease mechanism of action involves the modulation of the visual cycle by inhibiting a critical enzyme in this pathway, Retinal pigment epithelium-specific 65 kDa protein (RPE65). By slowing the visual cycle, Emixustat reduces the availability of vitamin A derivatives (11-cis-and all-trans-retinal) to form precursors of A2E and related compounds. In animal models of Stargardt disease and retinal degeneration, Emixustat has demonstrated the ability to decrease the accumulation of A2E and protect the retina from light-induced damage.

In human clinical studies, orally delivered Emixustat has been generally well tolerated. An interesting pharmacological observation is a delayed dark adaptive response in an electrical retinogram, which is considered a common sign of Emixustat’s effect. In August 2020, Kubota Vision Inc., a clinical-stage ophthalmology company and a wholly-owned subsidiary of Kubota Pharmaceutical, announced that the US FDA Office of Orphan Products Development (OOPD) had awarded an orphan products clinical trial grant to support the Phase III study of emixustat in Stargardt disease.

• MCO-010: Nanoscope Therapeutics

Nanoscope’s MCO-010 is an optogenetic gene therapy that utilizes a convenient and well-established intraocular injection to deliver a gene encoding the ambient light-sensitive MCO protein into retinal cells. Multi-Characteristic Opsin (MCO) re-sensitize the retina for detecting low light levels to restore vision in blind patients, specifically for the treatment of Stargardt disease, with the goal of improving visual function. The company’s lead asset, MCO-010, holds the potential to restore vision in millions of visually impaired individuals suffering from retinal degenerative diseases, including Stargardt Disease and others. The company has fully enrolled in the Phase II STARLIGHT trial of MCO-010 therapy in Stargardt patients.

In January 2023, Nanoscope Therapeutics Inc. announced that the US FDA had granted Fast Track Designation (FTD) to MCO-010.

Stargardt Disease Market Outlook

Stargardt disease is a rare genetic eye disease that occurs when fatty material builds up on the macula, the small part of the retina responsible for sharp, central vision. It is caused by a mutation in the ABCA4 gene (also caused by other genes in some instances), which prevents the production of a protein that cleans up the fatty material left over from vitamin A metabolism. As a result, the fatty material accumulates in yellowish clumps on the macula, eventually killing the light-sensitive cells and destroying central vision.

Currently, no treatment modality is recommended by the FDA to prevent or reverse visual loss in Stargardt Disease Patients. Stargardt Disease Patients are advised to avoid smoking, avoid taking supplements containing vitamin A, and also to use photoprotection to delay the disease progression. Low-vision aids are also recommended for visual assistance in those with visual field loss, and proper refractive correction is prescribed. Intravitreal anti-vascular endothelial growth factor (VEGF) injections are the preferred treatment modality for patients developing choroidal neovascular membrane, which is a rare and late complication.

Many new molecules with novel mechanisms, like emixustat, gildeuretinol, tinlarebant, avacincaptad pegol, among others, and gene therapies like MCO-010 and others, are being developed for the treatment of Stargardt disease by key Stargardt Disease Companies like Kubota Vision, Nanoscope Therapeutics, Alkeus Pharmaceuticals, Belite Bio, Astellas Pharma, among others.

In conclusion, despite the lack of appropriate treatment in the current Stargardt Disease treatment market landscape, many potential therapies with novel mechanisms are expected to enter the market, resolving a dire unmet need and leading to significant improvement in the treatment outcome of Stargardt disease patients. Hence, with the upcoming availability of new treatment options and increasing healthcare spending across the 7MM, the Stargardt Disease treatment market scenario is expected to experience significant growth during the forecast period (2024–2034). The expected launch of innovative therapies during the forecast period (2024–2034), coupled with an expanding diagnosed patient pool, is anticipated to significantly boost the Stargardt disease market. Advances in gene therapy, visual cycle modulation, and other targeted approaches underscore the growing commitment of biotech companies to bring transformative solutions to patients. Collectively, these efforts are set to drive a major positive shift in the market landscape in the coming years.
