  • Oral N-acetylcysteine for Retinitis Pigmentosa

    open to eligible people ages 18-65

    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 gradual constriction of side vision that eventually causes tunnel vision. Oxidative stress contributes to cone degeneration. N-acetylcysteine (NAC) reduces oxidative stress and in animal models of RP it slowed cone degeneration. In a phase I clinical trial in patients with RP, NAC taken by month for 6 months caused some small improvements in two different vision tests suggesting that long-term administration of NAC might slow cone degeneration in RP. NAC Attack is a clinical trial being conducted at many institutions in the US, Canada, Mexico, and Europe designed to determine if taking NAC for several years provides benefit in patients with RP.

  • RTx-015 Injection in Retinitis Pigmentosa Patients (ENVISION)

    open to eligible people ages 18 years and up

    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.

  • PRPF31 Mutation-Associated Retinal Dystrophy

    open to eligible people ages 10 years and up

    The purpose of this study is to characterize the natural history through temporal systemic evaluation of subjects identified with PRPF31 mutation-associated retinal dystrophy, also called retinitis pigmentosa type 11, or RP11. Assessments will be completed to measure and evaluate structural and functional visual changes including those impacting patient quality of life associated with this inherited retinal condition and observing how these changes evolve over time.

  • Retinal Imaging in Patients With Inherited Retinal Degenerations

    open to eligible people ages 13 years and up

    The purpose of this study is to determine whether the structure and function of the human retina can be studied with high resolution in patients with inherited retinal degenerations using the Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO).

  • Universal Rare Gene Study: A Registry and Natural History Study of Retinal Dystrophies Associated With Rare Disease-Causing Genetic Variants

    open to eligible people ages 4 years and up

    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

  • Autologous Intravitreal Bone-marrow CD34+ Stem Cells for Retinopathy

    “We hope to learn more about the safety and feasibility of using your own (autologous) stem cells extracted from your bone marrow.”

    Sorry, in progress, not accepting new patients

    This pilot study is to determine whether it would be safe and feasible to inject CD34+ stem cells from bone marrow into the eye as treatment for patients who are irreversibly blind from various retinal conditions.

  • Long-term Safety and Efficacy Follow-up of BIIB111 for the Treatment of Choroideremia and BIIB112 for the Treatment of X-Linked Retinitis Pigmentosa

    Sorry, accepting new patients by invitation only

    The objective of the study is to evaluate the long-term safety and efficacy of a sub-retinal injection of BIIB111 in participants with Choroideremia (CHM) who have been previously treated with BIIB111 and who have exited an antecedent study; these treated participants will be compared with untreated control participants who have exited the STAR (NCT03496012) study and BIIB112 in participants with X-linked retinitis pigmentosa (XLRP) who have been previously treated with BIIB112 and who have exited an antecedent study.

  • OCU400 for Retinitis Pigmentosa and Leber Congenital Amaurosis

    Sorry, in progress, not accepting new patients

    This is a Phase 1/2 Study to Assess the Safety and Efficacy of OCU400 in patients with retinitis pigmentosa associated with NR2E3 and RHO mutations and in patients with LCA due to mutation(s) in CEP290 gene (OCU400-101). To document prospective eye pathology in the above subjects Investigators will also conduct a Natural History Study (OCU400-104)i This is a multicenter study, which will be conducted in two phases and will enroll up to a total of 24 subjects in the OCU400-101 and 100 subjects in the OCU400-104 study.

  • Rate of Progression in EYS Related Retinal Degeneration

    Sorry, in progress, not accepting new patients

    The overall goal of this project funded by the Foundation Fighting Blindness is to characterize the natural history of disease progression in patients with EYS mutations in order to accelerate the development of outcome measures for clinical trials.

  • Rate of Progression in USH2A-related Retinal Degeneration

    Sorry, in progress, not accepting new patients

    The overall goal of this project funded by the Foundation Fighting Blindness is to characterize the natural history of disease progression in patients with USH2A related retinal degeneration associated with congenital hearing loss (Usher syndrome type 2a) or non-syndromic retinitis pigmentosa (RP39). RUSH2A Extension Study: The purpose of this addendum is to extend RUSH2A to 7- and 9-year visits, with the goal to use longer term data to further develop and support early candidate endpoints as possible clinical trial outcomes.
