This will be a non-randomized, open-label, Phase 1/2 study of the safety and efficacy of AGTC-402, administered to one eye by subretinal injection in individuals with achromatopsia caused by mutations in the CNGA3 gene. The primary study endpoint will be safety and the secondary study endpoint will be efficacy.
This will be a non-randomized, open-label, Phase 1/2 study of the safety and efficacy of AGTC-402 administered to one eye by subretinal injection in individuals with achromatopsia caused by mutations in the CNGA3 gene. The primary study endpoint will be safety and the secondary study endpoint will be efficacy.
Subjects will be enrolled sequentially in four groups. Subjects in Groups 1, 2 and 3 will be between 18 and 55 years of age, inclusive, and will receive a lower, middle or higher dose of study agent. Subjects in Group 4 will be between 6 and 55 years of age, inclusive, and will receive the maximum tolerated dose identified in Groups 1, 2 and 3.
Safety will be monitored by evaluation of ocular and non ocular adverse events and hematology and clinical chemistry parameters. Efficacy parameters will include visual acuity, light discomfort testing, color vision, static visual field, ERG, adaptive optics retinal imaging and OCT.
Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

This will be a non-randomized, open-label, Phase 1/2 study of the safety and efficacy of rAAV2tYF-PR1.7-hCNGB3 administered to one eye by subretinal injection in individuals with achromato...
The purpose of this study is to proof the safety and efficacy of a single subretinal injection of rAAV.hCNGA3 in patients with CNGA3-linked achromatopsia.
Achromatopsia is a recessively inherited condition characterised by a lack of cone photoreceptor function resulting in impairment of colour vision and visual acuity, central scotoma often ...
Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as P...
While basic visual functions have been described in subjects with congenital achromatopsia (ACHM), little is known about their mid- or high-level cortical visual processing. We compared midlevel corti...
Congenital achromatopsia (ACHM) is an autosomal recessive disorder in which cone function is absent or severely reduced. Gene therapy in animal models of ACHM have shown restoration of cone function, ...
The 2 most common causative genes for achromatopsia (ACHM) are CNGA3 and CNGB3; other genes including GNAT2 account for only a small portion of ACHM cases. The cone mosaics in eyes with CNGA3 and CNGB...
We report on two brothers with visual impairment, and non-syndromic alopecia in the elder proband. The parents were first-degree Pakistani cousins. Whole exome sequencing of the elder brother and pare...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
