简要总结
A prospective natural history study with systematic assessments and uniform follow-up to provide a high-quality dataset for assisting in the design of future clinical treatment trials involving patients with CEP290-related retinal degeneration caused by the common intron 26 mutation.
详细描述
The purpose of the study is to describe the natural history of CEP290-related retinal degeneration caused by a compound heterozygous or homozygous intron 26 c.2991+1655A>G mutation and to better understand the best assessments for evaluation of patients with this condition in a future interventional trial. Patients meeting the entry criteria will be enrolled in the study. Visits will occur at Screening, Baseline, and Months 3, 6, and 12, for a total duration of 1 year.

入选标准
- •Patient and/or parent/legal guardian must complete/sign an informed consent form (ICF). If required on a per patient basis, provisions can be made for alternative forms of consent (eg, witnessed consent). Where required by the IRB/IEC, minors must also verbalize or sign a confirmation of assent.
- •At least 3 years of age at screening.
- •Has abnormally decreased vision, defined as having light perception to 20/50 visual acuity in each eye, with examination and test results consistent with an inherited retinal degeneration due to mutations in the CEP290 gene.
- •Has CEP290-related retinal degeneration caused by a compound heterozygous or homozygous intron 26 c.2991+1655A>G mutation (ie, 1 or 2 copies of the intron 26 c.2991+1655A>G mutation) confirmed by deoxyribonucleic acid sequencing.
- •Has ability to cooperate with assessments relative to age.
- •Has clear ocular media and adequate pupil dilation in at least 1 eye, to permit good quality fundus examination and optical coherence tomography (OCT) imaging.
排除标准
- •Has history or current evidence of a medical condition (systemic or ophthalmic disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding) that may, in the opinion of the Investigator, preclude adherence to the scheduled study visits, safe participation in the study, or affect the results of the study (eg, uncontrolled systemic hypertension, autoimmune disease, advanced coronary artery disease, or cerebral vascular disease, other unstable or progressive cardiovascular, pulmonary, Parkinson's, liver or renal disease, cancer, or dementia).
- •Has history or current evidence of ocular disease in either eye that, in the opinion of the Investigator, may confound assessment of this inherited retinal disease or the assessments utilized herein (eg, glaucoma, age-related macular degeneration, diabetic retinopathy, uveitis, or the presence of any condition that precludes adequate visualization of the fundus such as dense cataracts or corneal scarring).
- •Achieves a passing score for the Visual Function Navigation Test at the maximum level of difficulty (ie, passes the most challenging Visual Function Navigation Test under the dimmest lighting conditions) with each eye independently and both eyes together.
- •Is currently receiving gene therapy and/or has received gene therapy.
- •Is currently enrolled in an investigational or interventional drug or device study and/or has participated in such a study within 30 days of Screening.
