Biallelic RPE65 mutation-associated retinal dystrophy is a form of IRD caused by biallelic pathogenic variants in RPE65; it presents as a spectrum of disease with variable age of onset and progression of vision loss. Common clinical findings across the spectrum include night blindness, progressive loss of visual fields and loss of central vision.

In LCA, night blindness often occurs from birth. Characteristically, these patients have residual cone-mediated vision in the first to third decades with progressive visual field loss until complete blindness is observed, most often in mid- to late-adulthood. A range of age of onset has been described for night blindness in RP, but it typically onsets in later childhood.

In December 2017, the FDA approved LUXTURNA (voretigene neparvovec-rzyl) gene therapy for the treatment of patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy. The FDA’s conclusion of efficacy is based on improvement in a functional vision score over 1 year in a single open-label controlled Phase 3 study of 31 affected patients. The average age of the 31 randomized patients was 15 years (range 4 to 44 years), including 64% pediatric subjects (n=20, age from 4 to 17 years) and 36% adults (n=11). Functional vision was scored by a patient’s ability to navigate a course in various luminance levels. Using both treated eyes of the 21 subjects in the LUXTURNA treatment group, 11 (52%) had a clinically meaningful score improvement, while only one of the ten (10%) subjects in the control group had a clinically meaningful score improvement. Using the first treated eye only, 15/21 (71%) had a clinically meaningful score improvement, while no comparable score improvement was observed in controls. Other secondary clinical outcomes were also examined. Analysis of white light full-field light sensitivity threshold testing showed statistically significant improvement at 1 year in the LUXTURNA treatment group compared to the control group. The change in visual acuity was not significantly different between the LUXTURNA and control groups.

LUXTURNA is administered subretinally by injection. Per the FDA package insert, the most common adverse reactions (incidence ≥ 5%) in the clinical trials for LUXTURNA included conjunctival hyperemia, cataract, increased intraocular pressure, retinal tear, dellen (thinning of the corneal stroma), and macular hole. Several other ocular adverse effects were also reported, including risk of endophthalmitis. Safety data was included on the basis of 41 patients (81 eyes).

For review: availability of therapy?
