18 Clinical Trials for Various Conditions
Aberrant retinoic acid signaling driven by the degenerating outer retina leads to pathological changes to the inner retina. The resulting hyperactivity of retinal ganglion cells leads to further diminution of the remaining vision in those afflicted with inherited retinal diseases. Inhibition of this pathway has led to improved visual function in murine models of retinal degeneration. This can be accomplished in humans with the FDA-approved irreversible inhibitor of aldehyde dehydrogenases, disulfiram.
The study is a Phase 3, open-label, randomized controlled trial of gene therapy intervention by subretinal administration of AAV2-hRPE65v2 (voretigene neparvovec-rzyl). At least twenty-four subjects, three years of age or older, will be recruited. The intervention group will receive AAV2-hRPE65v2 at either The Children's Hospital of Philadelphia or University of Iowa to determine if it improves visual and retinal function in individuals with RPE65 gene mutations.
The purpose of this study is to evaluate the safety, tolerability and efficacy of a single escalating doses of EDIT-101 administered via subretinal injection in participants with LCA10 caused by a homozygous or compound heterozygous mutation involving c.2991+1655A\>G in intron 26 of the CEP290 gene ("LCA10-IVS26").
This study is an open-label, single ascending dose clinical trial in participants who have ABCA4-related retinopathies. This is the first-in-human clinical trial in which ACDN-01 will be evaluated for safety, tolerability, and preliminary efficacy following a single subretinal injection of ACDN-01.
This is an observational prescreening study. Individuals who are eligible for prescreening will undergo testing procedures that may be used to determine eligibility in ACDN-01 clinical trials.
The goal of this observational study is to utilize a novel imaging system designed for high-resolution retinal imaging of neonates, infants and children to identify the signs of photoreceptor development and degeneration in children with early-onset inherited retinal dystrophies (EORDs). Participants will have research imaging with SS-HH-OCT at the time of clinically-indicated eye examinations or procedures. The investigators aim to establish the basis for utilization of OCT imaging in earlier diagnosis and disease monitoring in children with EORDs. This work will set data reference standards and IRD endpoints that can be used in clinical trials.
The objective of this study is to collect long-term safety information (i.e., for 5 years after treatment) associated with voretigene neparvovec-rzyl (vector and/or transgene), its subretinal injection procedure, the concomitant use of corticosteroids, or a combination of these procedures and products. The enrollment period will last for two years from the first treatment following product approval (through 31March2020) and include a minimum of 40 patients.
This study is a multi-country retrospective and cross-sectional observational study of affected LHON subjects, based on retrospective subjects' medical chart abstractions and cross-sectional administration of patient-reported outcomes (PROs).
The goal of this clinical trial is to assess the safety and efficacy of GS010, a gene therapy, in improving the retina functional \& structural outcomes in subjects with LHON due to the G11778A ND4 mitochondrial mutation when vision loss duration is present up to one year.
This is an international, multicenter study with two components: Registry * A standardized genetic screening and a prospective, standardized, cross-sectional clinical data collection * Enrollment is open to all genes on the RD Rare Gene List Natural History Study * A prospective, standardized, longitudinal Natural History Study * Enrollment opens gene-by-gene, based on funding and within-gene Registry enrollment The study objectives are as follows. Registry Objectives 1. Genotype Characterization 2. Cross-Sectional Phenotype Characterization (within gene) 3. Establish a Link to My Retina Tracker Registry (MRTR) 4. Ancillary Exploratory Studies - Pooling of Genes Natural History Study Objectives 1. Natural History (within gene) 2. Structure-Function Relationship (within gene) 3. Risk Factors for Progression (within gene) 4. Ancillary Exploratory Studies - Pooling of Genes
The My Retina Tracker® Registry is sponsored by the Foundation Fighting Blindness and is for people affected by one of the rare inherited retinal degenerative diseases studied by the Foundation. It is a patient-initiated registry accessible via a secure on-line portal at www.MyRetinaTracker.org. Affected individuals who register are guided to create a profile that captures their perspective on their retinal disease and its progress; family history; genetic testing results; preventive measures; general health and interest in participation in research studies. The participants may also choose to ask their clinician to add clinical measurements and results at each clinical visit. Participants are urged to update the information regularly to create longitudinal records of their disease, from their own perspective, and their clinical progress. The overall goals of the Registry are: to better understand the diversity within the inherited retinal degenerative diseases; to understand the prevalence of the different diseases and gene variants; to assist in the establishment of genotype-phenotype relationships; to help understand the natural history of the diseases; to help accelerate research and development of clinical trials for treatments; and to provide a tool to investigators that can assist with recruitment for research studies and clinical trials.
Background: - People with rod-cone dystrophy (RCD) or enhanced S-cone syndrome (ESCS) have excess fluid under the retina of their eye. This can cause vision loss. The medicine interferon gamma-1b may help people with these diseases. Objectives: - To see if interferon gamma-1b eyedrops are safe for people with RCD or ESCS. To see if the medicine can decrease retina fluid and help prevent vision loss. Eligibility: - People at least 12 years old with RCD or ESCS. Those with ESCS must have two mutations in the NR2E3 gene. Design: * Participants will be screened with medical history, physical exam, eye exam, and blood tests. * Participants will stay at NIH for 3 days and get the first eyedrops. * Participants will give themselves 4 study eyedrops 4 times daily for 2 weeks and keep a diary. * Participants will have 5 outpatient visits over 8 weeks, 2 of which are telephone assessments. They may have: * Repeats of screening tests. * Questionnaires. * Small piece of skin removed. * Eye exams, including eye dilation and tasks on computer screens. * Fluorescein angiography. A dye injected into an arm vein will travel to the blood vessels in the eyes. A camera will take pictures. * Electroretinography. Participants will sit in the dark wearing eyepatches. A small electrode will be taped to the forehead. After 30 minutes, researchers will remove the eyepatches and put in numbing eyedrops and contact lenses. Participants will watch flashing lights. * Electrooculography. Electrodes will be attached outside of the eyes and eye function will be measured in the dark and the light. * Participants will have a follow-up visit after 52 weeks.
This study aims to prepare for the first-in-human clinical trial of cone optogenetics vision restoration. As a first step, this worldwide multicenter ocular imaging study (EyeConic Study) is performed to identify eligible patients.
Study OpCT-001-101 is a Phase 1/2a first-in-human, multisite, 2-part interventional study to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001 in up to approximately 54 adults with primary photoreceptor (PR) disease. Phase 1 will focus on safety and features a dose-escalation design. Phase 2 is designed to gather additional safety data and assess the effect of OpCT-001 on measures of visual function, functional vision, and anatomic measures of engraftment in different clinical subgroups.
