Usher Syndrome Disease Understanding and Treatment Algorithm

Usher Syndrome Overview

Usher Syndrome (USH) is the most common deaf-blind syndrome, with 50% of deaf-blindness in persons younger than 65 years of age. It is a genetic condition that includes hearing loss, retinopathy (retinitis pigmentosa), and vestibular areflexia with different entities and onset. It is an autosomal recessive disorder - passing from parents to children - that impacts three major senses in the body: vision, hearing and balance. Balance disorders and bilateral vestibular areflexia are also observed in some cases. USH has been grouped into three main clinical types: 1, 2, and 3, which are caused by mutations in different genes and are further divided into different subtypes.

Usher Syndrome Diagnosis

Diagnosis of Usher Syndrome involves pertinent questions regarding the person's medical history and testing of hearing, balance, and vision. A hearing (audiologic) exam measures the frequency and loudness of sounds that a person can hear. An electroretinogram measures the electrical response to the light-sensitive cells in the retina of the eyes. A retinal exam is done to observe the retina and other structures in the back of the eye. Vestibular (balance) function can be assessed by a variety of tests that evaluate different parts of the balance system. Genetic testing is clinically available for most of the genes associated with Usher Syndrome.

Further details related to diagnosis will be provided in the report.

Usher Syndrome Treatment

Presently, there is no cure for Usher Syndrome. Treatment involves managing hearing, vision, and balance problems. Some researchers have shown that taking a specific daily dose of vitamin A may slow the progression of retinal degeneration in some people with typical RP and Usher Syndrome type 2. Typically, treatment for hearing management includes hearing aids, assistive listening devices, cochlear implants, or other communication methods. Although some ophthalmologists believe that a high dose of vitamin A palmitate may slow, but not halt the progression of retinitis pigmentosa. Other treatments such as gene therapy, drug based therapy, artificial organ replacement are currently leading the market. Ongoing research on the Usher proteins function in auditory and visual cells will be important in determining the optimal target for gene replacement therapy.

Emerging Drugs

NPI-001: Nacuity Pharmaceuticals

NPI-001 is a differentiated, purified, prescription-quality, GMP-grade N-acetylcysteine amide (NACA) being developed to treat a broad set of diseases and conditions associated with oxidative stress and reduced glutathione levels. In preclinical animal studies, NPI-001 preserved photoreceptor cells and functionality. A Phase I clinical trial of Nacuity's GMP-grade NPI-001 solution in healthy volunteers was completed with no serious adverse events. Currently, the company is investigating iptacopan in the Phase I/II trial (NCT04355689) for the treatment of patients with RP (retinitis pigmentosa) associated with Usher Syndrome.

Ultevursen: Laboratoires Thea

Ultevursen (formerly QR-421a) is a first-in-class investigational RNA therapy designed to address the underlying cause of vision loss in Usher Syndrome type 2a and non-syndromic USH due to mutations in exon 13 of the USH2A gene. QR-421a is designed to restore functional usherin protein by using an exon-skipping approach with the aim of stopping or reversing vision loss in patients. Ultevursen is intended to be administered through intravitreal injections in the eye and has been granted Orphan Drug Designation in the US and the European Union and received Fast Track and Rare Pediatric Disease Designations from the FDA. Currently, Ultevursen is being investigated in a Phase II/III trial, SIRIUS, for treating Usher Syndrome Type 2.

Drug Class Insight

Free radical scavenger

Free radical scavengers play a role in the treatment of Usher Syndrome by helping to reduce oxidative stress, which is implicated in the progression of the disease. Usher Syndrome is a genetic condition characterized by hearing loss and vision impairment, including retinitis pigmentosa. Research has shown that free radical scavengers, such as minocycline, nanoceria, and edaravone, possess antioxidant properties that can help reduce reactive oxygen species (ROS) levels and increase the expression of antioxidant-associated proteins in the retina. This can potentially contribute to the preservation of retinal function in conditions like retinitis pigmentosa, which is a major hallmark of Usher Syndrome.

Usher Syndrome Market Outlook

Currently, LUXTURNA (voretigene neparvovec) is the only approved therapy for Usher Syndrome and is only authorized for the treatment of a small subpopulation of patients that have the RPE65 mutation. There is currently no standard treatment for patients without the RPE65 mutation; therefore, most patients are limited to the best supportive care, including reliance on vitamin supplements, protection from sunlight, and visual aids. Only few key players are active in the pipeline such as Nacuity Pharmaceuticals and Laboratoires Thea for the treatment of Usher Syndrome.

Based on randomized clinical trials with vitamins and supplements, the only widely recommended treatment is supplementation with high-dose vitamin A palmitate and fish oil, along with avoidance of vitamin E, but these adjustments only delay degeneration. However, a comparison of seven clinical trials that measured visual acuity as a secondary outcome indicator showed that no significant difference was found in the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity with different doses of vitamin A and vitamin E in Usher Syndrome across treatment groups. Groups were either administered high-dose vitamin A, high-dose vitamin E, high-dose vitamin A and E, or trace amounts of both vitamins. This indicates that vitamin supplementation may have no beneficial effect in Usher Syndrome patients. Consequently, for most patients with Usher Syndrome, there is currently no cure or effective treatment to slow or stop disease progression.

The precise mechanism by which vitamin A supplementation provides its benefit is not known. It has been speculated that vitamin A rescues remaining cones, thereby explaining how one supplement may help a group of patients with different rod-specific gene defects. Vitamin E may lead to an adverse effect on the course of Usher Syndrome by inhibiting the absorption or transport of vitamin A.

Detailed market assessment will be provided in the final report.
