Stargardt Disease Market

Stargardt Disease Market Summary

In 2023, the United States led the Stargardt Disease treatment market, accounting for nearly 55% of the global share, followed by the EU4, the UK, and Japan. Stargardt disease, a rare autosomal recessive macular dystrophy caused by ABCA4 gene mutations, results in lipofuscin accumulation in the retinal pigment epithelium, leading to central vision loss. It is the most common recessive macular dystrophy in children, affecting approximately 10–12.5 per 100,000 individuals in the U.S., with earlier onset correlating with more severe progression. Diagnosis relies on family history, visual acuity, fundus examination, visual field testing, fundus autofluorescence, and OCT imaging. Currently, no standard therapies exist to prevent or reverse vision loss; management includes low-vision aids, sunlight avoidance, vitamin A restriction, and anti-VEGF injections for choroidal neovascularization. Emerging pipeline candidates such as ALK-001, Tinlarebant, IZERVAY, Emixustat, and gene therapies like MCO-010 are expected to drive market growth between 2024 and 2034, addressing unmet needs caused by disease heterogeneity and diagnostic challenges.

Stargardt Disease Overview

Stargardt disease, also known as Stargardt macular dystrophy or juvenile macular degeneration, is a genetic eye disorder that affects the macula, a small area near the center of the retina responsible for sharp, central vision. It is typically diagnosed in childhood or adolescence. Stargardt disease is characterized by the gradual degeneration of the cells in the macula, leading to progressive central vision loss.

Stargardt Disease Market Outlook

In 2023, the total Stargardt Disease treatment market size was around USD 27 million, which is expected to increase by 2034 during the study period (2020 – 2034) in the 7MM.

Stargardt disease is a rare genetic eye disorder caused primarily by mutations in the ABCA4 gene, leading to the accumulation of fatty material on the macula, which gradually destroys central vision. Currently, no FDA-approved treatments exist to prevent or reverse vision loss. Management focuses on lifestyle modifications such as avoiding smoking and vitamin A supplements, using photoprotection, employing low-vision aids, and correcting refractive errors. In rare cases of choroidal neovascularization, intravitreal anti-VEGF injections are used.

Several novel therapies and gene treatments—including emixustat, gildeuretinol, tinlarebant, avacincaptad pegol, and MCO-010—are under development by companies like Kubota Vision, Nanoscope Therapeutics, Alkeus Pharmaceuticals, Belite Bio, and Astellas Pharma. These emerging therapies are expected to address the significant unmet need, improve patient outcomes, and drive substantial growth in the Stargardt disease treatment market across the 7MM between 2024 and 2034.

Stargardt Disease Epidemiology

In 2023, the United States had the highest share of diagnosed Stargardt disease cases among the 7MM, representing 43% of total diagnosed-incident cases. In the U.S., disease onset was most common in individuals over 20 years, particularly those aged 20–39, while cases were lowest in those aged 60 and above. Within the EU4 and the UK, Germany reported the highest prevalence, followed by the UK, with Spain having the lowest. In Japan, the most frequently reported symptoms among symptomatic patients were reduced vision, followed by nyctalopia, photophobia, and other visual impairments.

Stargardt Disease Drugs Uptake and Pipeline Development Activities

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.
