Rod and Cone Mediated Function in Retinal Disease
Background: Retinal diseases cause the loss of rod and cone photoreceptors. Symptoms include vision loss and night blindness. Researchers want to learn about rod and cone function in healthy people and people with retinal disease. They want to know if how well a person sees in the dark can test the severity of retinal disease.
Generation of Induced Pluripotent Stem (iPS) Cell Lines From Somatic Cells of Participants With Eye Diseases and From Somatic Cells of Matched Controls
Background: - Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, and blood can be used for research. Researchers want to collect cells from people...
An Open-label, Multicenter, Phase 2 Follow-on Study for Second Eye Treatment of Patients Previously Treated With a Recombinant Adeno-associated Virus Vector (AAV5 hRKp.RPGR) for Gene Therapy of Adults and Children With X-linked Retinitis Pigmentosa Owing to Defects in Retinitis Pigmentosa GTPase Regulator (RPGR)
Summary: The purpose of this study is to assess the safety and tolerability of subretinal delivery of Adeno-associated Virus Vector (AAV5 hRKp.RPGR) gene therapy in adults and children with X-linked retinitis pigmentosa.
A Phase 3, Multi-Center, Randomized Study to Assess The Efficacy, Safety and Tolerability of Subretinal OCU400 Gene Therapy for the Treatment of Retinitis Pigmentosa
Summary: This is a Phase 3 study to Assess the Efficacy, Safety and Tolerability of OCU400 in patients with retinitis pigmentosa (RP) associated with RHO mutations and patients with any other RP associated mutation with a clinical phenotype of RP. This is a multicenter, assessor blinded and randomized study which will enroll 150 subjects.
A Randomized, Controlled, Masked, Multi-center Study Evaluating the Efficacy, Safety, and Tolerability of Two Doses of AGTC-501 Compared to an Untreated Control Group in Male Participants With X-linked Retinitis Pigmentosa
Summary: This study will evaluate and compare the safety, efficacy, and tolerability of 2 doses of a recombinant adeno-associated virus vector (AGTC-501/laruparetigene zovaparvovec )) to an untreated control group in male participants with X-linked retinitis pigmentosa caused by RPGR mutations.
Universal Rare Gene Study: A Registry and Natural History Study of Retinal Dystrophies Associated With Rare Disease-Causing Genetic Variants
Summary: 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 Regi...
A Two-Year Double-masked, Randomized, Sham-Controlled Study to Evaluate the Efficacy, Safety and Tolerability of Ultevursen in Subjects with Retinitis Pigmentosa (RP) Due to Mutations in Exon 13 of the USH2A Gene
Summary: The purpose of this Phase 2b study is to evaluate the safety and tolerability of Ultevursen administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene. This is a multicenter Double-masked, Randomized, Sham-controlled study which will enroll 81 subjects.
NAC Attack, A Phase III, Multicenter, Randomized, Parallel, Double Masked, Placebo-Controlled Study Evaluating the Efficacy and Safety of Oral N-Acetylcysteine in Patients With Retinitis Pigmentosa
Summary: Retinitis pigmentosa (RP) is an inherited retinal degeneration caused by one of several mistakes in the genetic code. Such mistakes are called mutations. The mutations cause degeneration of rod photoreceptors which are responsible for vision in dim illumination resulting in night blindness. After rod photoreceptors are eliminated, gradual degeneration of cone photoreceptors occurs resulting in gra...
Phase 3 Study to Evaluate the Safety and Efficacy of AAV5-hRKp.RPGR for the Treatment of Japanese X-linked Retinitis Pigmentosa Associated With Pathogenic Variants in Retinitis Pigmentosa GTPase Regulator (RPGR)
Summary: The purpose of the study is to assess the safety and tolerability of bilateral subretinal delivery of adeno-associated virus vector with a serotype 5 capsid human rhodopsin kinase promoter. retinitis pigmentosa guanosine triphosphatase regulator (AAV5-hRKp.RPGR).
Open Label, Interventional Single Arm Study Evaluating a New Peptide Therapy for Retinal Diseases: AMD, Diabetic Retinopathy, and Dystrophies
Objectives: Primary Objectives: Assess safety and tolerability, and evaluate the therapy's effects on retinal function and structure. Secondary Objectives: Explore improvements in visual acuity, retinal thickness, vascular health, and disease biomarkers. Study
Phase 1, Open-Label, Dose-Escalation Study to Evaluate Safety of a Single Intravitreal Injection of RTx-015 in Patients With Retinitis Pigmentosa (ENVISION)
Summary: A Phase 1, open-label, non-randomized, dose-escalation study, where approximately 9 eligible patients with retinitis pigmentosa will be enrolled sequentially in up to 3 dose cohorts of RTx-015. Enrolled patients will receive a single, unilateral intravitreal injection of RTx-015 in the study eye at Visit 3 (Day 0) and be followed for a total of 12 months.
Observational, Non-Interventional Study to Determine the Operational Feasibility and Measurement Properties of Endpoints in Patients with Retinal Degeneration
Summary: The Vision Research and Assessment Institute (VRAI) was established with the purpose of serving as a testing facility for efficacy endpoints for patients with Low Vision. The mission of the VRAI is to enable the highest quality, standardized efficacy testing of patients with visual impairment. The VRAI facilitates the development and refinement of existing endpoints specifically for testing patien...
