Retinitis PigmentosaChoroideremiaA phase I/II dose-escalating study of the safety, tolerability and efficacy of KIO-301 administered intravitreally to patients with retinitis pigmentosa and choroideremia (ABACUS). Open label.
Dose Escalation Study of Intravitreal 4D-110 in Patients With Choroideremia
ChoroideremiaThis study will evaluate safety, tolerability, and preliminary efficacy of a single intravitreal (IVT) injection of a recombinant adeno-associated virus (AAV) gene therapy, 4D-110, in male patients with genetically-confirmed Choroideremia (CHM).
Long-term Safety and Efficacy Follow-up of BIIB111 for the Treatment of Choroideremia and BIIB112...
ChoroideremiaX-Linked Retinitis PigmentosaThe 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.
High Resolution Retinal Imaging
StargardtsRetinitis Pigmentosa3 moreStudying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective of this study is to obtain and analyze high-resolution images of the retina, in particular by imaging the cone photoreceptor mosaic, the retinal vasculature and other retinal layers. The study design will involve case-control studies, where cases are followed over time. Subjects age 7 and older may be invited to participate. The main research procedure involves retinal imaging with the AOSLO. The primary endpoint is the observation of differences in retinal images between subjects with and without retinal diseases. These changes will be quantified by examining the cell density, size, spacing and regularity of the cone photoreceptor mosaic, as well as examining the differences between other retinal layers.
Longitudinal Study of a Bionic Eye
Retinitis PigmentosaChoroideremiaThis is a longitudinal observational study with participants who have been implanted with the suprachoroidal retinal prosthesis.
Structural and Functional Characterization of Rare Ocular Diseases
Retinitis PigmentosaStargardt Disease 13 moreRare ocular diseases (ROD) are a heterogeneous group of ocular diseases that affect very few people and, generally, for which no tretament is available. An important subgroup of these diseases are inherited retinal degenerations. In this study we focus on understanding the natural history of different ROD that affect the posterior segment.
Inherited Retinal Degenerative Disease Registry
Eye Diseases HereditaryRetinal Disease26 moreThe 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.
REP1 Gene Replacement Therapy for Choroideremia
ChoroideremiaThe assessment of the efficacy (with respect to preservation of visual function and retinal structure) and safety of a single subretinal injection of AAV2.REP1 in participants with a confirmed diagnosis of choroideremia, as evaluated by various functional and anatomical outcomes measured over a number of time points up to 24 months post-treatment.
Compensation for Blindness With the Intelligent Retinal Implant System (IRIS V2) in Patients With...
Retinitis PigmentosaCone Rod Dystrophy1 moreThis study evaluates the safety and effectiveness of the Intelligent Retinal Implants System (IRIS V2). Blind patient suffering from Retinitis Pigmentosa, Cone Rod Dystrophy, or Choroideremia are implanted with an Intelligent Retinal Implant Systeme. All subjects undergo ophthalmological examinations in predefined intervals after implantation. Ophthalmological examinations include funduscopy, slit lamp examination and OCT. All adverse events are recorded and analyzed. Efficacy is measured using functional vision and visual function tests before and after implantation as well as with the system on and system off.
