Filter by: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.
RayTx established The Vision Research and Assessment Institute (VRAI) with the express 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 to be performed by expert clinicians in an optimized environment. The proposed assessments or testing modalities to be evaluated in this non-interventional study are published in some capacity, and some of these publications already include patients with severe-to-profound vision loss from retinitis pigmentosa and other inherited retinal diseases.
The aim of the study is to apply a novel clinical investigation protocol in patients with Phosphodiesterase 6A (PDE6A), PDE6B and Rhodopsin (RHO)-based retinitis pigmentosa. This novel, multimodal clinical examination protocol describes and correlates structural, functional and metabolic aspects during natural disease development. Test-retest variability of new measurements as well as correlations of the structural, functional, and metabolic changes will be defined to be able to define well-suited readouts for safety and efficacy of future treatment developments before they reach the clinical phase.
The objective of this study is to discover biomarkers that demonstrate a correlation between the severity of retinitis pigmentosa (RP) and the thickness of the retinal pigment epithelium (RPE). These biomarkers will serve as prognostic indicators for various kinds of retinitis pigmentosa. The objective of this study is to find biomarkers that establish a correlation between the severity of retinitis pigmentosa and the thickness of the retinal pigment epithelium (RPE), which can serve as a prognostic indicator for Retinitis Pigmentosa.
The goal of this phase 1 clinical trial is to learn about the safety and efficacy of a gene therapy, VG901, in patients with a rare disorder of the eye called Retinitis Pigmentosa. The main questions the study aims to answer are: - What is the best tolerated dose and are there any side effects, in particular any inflammatory reactions post drug administration? - Are there any early signs of efficacy on visual function? Participants will be administered a single intravitreal dose of VG901 into the most affected eye through a syringe and followed up for a year to monitor safety and efficacy. There will be two cohorts of participants in this study. Study Cohort 1 will receive the low dose and Study Cohort 2 will receive the high dose as specified in the Protocol.
The aim of this clinical trials is to evaluate the safety and efficacy of intravitreal injection of GMP-compliant BM-MSC-derived sEVs in patients with retinitis pigmentosa.
Background: Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that can be fatal. DPPMs are not well understood, and researchers want to learn more about what causes them and how to treat them. Objective: To learn more about factors that affect DPPMs by comparing test results from affected, uaffected family members, and healthy people. Eligibility: Three types of participants are needed: people aged 1 month and older with DPPMs; their family members who do not have DPPMs; and healthy volunteers. Design: Participants with DPPMs will come to the clinic once a year; some may be asked to come more often. At each visit, all affected participants will have a physical exam and give samples of blood, urine, saliva, and stool. Depending on their symptoms, they may also have other procedures, such as: Swabs of their skin and inside the mouth. Tests of their heart, kidney, brain, and nerve function. Questionnaires about what they eat. Dental exams, and exams of their hearing and vision. Tests of their learning ability. Monitoring of their physical activity. Imaging scans. Photographs of their face and body. These tests may be spread over up to 7 days. Affected participants may remain in the study indefinitely if they wish to. Healthy volunteers and family members will have 1 study visit. They will have a physical exam and may be asked to give blood, urine, saliva, and stool samples.
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).
The study will perform UC-MSCs and CM transplantation. There are two groups with different dosages. The first group will be transplanted with 1.5 million cells, meanwhile, the second group is 5 million cells. Each group consists of 30 subjects. All groups will be transplanted via the peribulbar route. All groups will be observed until six months.
