Eligibility criteria
Inclusion Criteria:
* Male or female, ≥ 6 years of age at Screening with a clinical diagnosis of LCA and a molecular diagnosis of homozygosity or compound heterozygosity for the CEP290 p.Cys998X mutation.
* Best-corrected visual acuity greater than or equal to light perception in both eyes and equal to or worse than LogMAR +1.0 (Snellen notation 20/200) in the worse eye and equal to or worse than LogMAR +0.7 (Snellen notation 20/100) in the contralateral eye.
* Detectable outer nuclear layer (ONL) in the area of the macula.
* An electroretinogram (ERG) result consistent with LCA.
* Clear ocular media and adequate pupillary dilation to permit good quality retinal imaging.
Exclusion Criteria:
* Syndromic disease.
* Pregnant or breast-feeding female.
* Any clinically significant cardiac disease or defect.
* One or more coagulation parameters outside of the normal range.
* Any ocular disease or condition that could compromise treatment safety, visual acuity or interfere with assessment of efficacy and safety.
* Prior receipt of intraocular surgery or intravitreal injection within 3 months prior to study start or planned intraocular surgery or procedure during the course of the study.
* Use of any investigational drug or device within 90 days or 5 half-lives of Day 1, whichever is longer, or plans to participate in another study of a drug or device during the PQ-110-001 study period.
* Any prior receipt of genetic therapy for LCA
