CPK850 is a recombinant adeno-associated virus 8 (AAV8) vector containing the human RLBP1 gene. The purpose of this first-in-human study is to explore the maximum tolerated dose (MTD) of CPK850 as determined by the single ascending dose ranging portion of the study. This study will also evaluate the safety and potential efficacy of CPK850 on improving visual function in patients with decreased visual function from RLBP1 retinitis pigmentosa due to biallelic mutations in the RLBP1 gene.
The aim of this study is to evaluate the efficacy of cognitive - behavioral therapy for the control of psychopathological stress and the disease of people with Retinitis Pigmentosa (RP).
The rod-cone dystrophies (often referred to as retinitis pigmentosa (RP)) are a clinically and genetically heterogeneous group of disorders in which there is progressive loss of rod and later cone photoreceptor function leading to severe visual impairment. RP usually occurs as an isolated retinal disorder, but it may also be seen in association with systemic abnormalities.
The study is a Phase I/II, monocentric, open-label, dose-ranging safety and efficacy gene therapy intervention by subretinal administration of AAV2/5-hPDE6B. At least twelve patients 18 years of age or older, within three consecutive cohorts of patients, will be recruited.
The objective of this study is to evaluate the safety and tolerability of escalating doses of a gene therapy called GS030-DP (injected study treatment) administered via a single intravitreal injection and repeated light stimulation using a medical device called GS030-MD (stimulating glasses) in subjects with documented diagnosis of non-syndromic Retinitis Pigmentosa
A new fundus-guided microperimeter, the MP-3S, has been developed by Nidek, Inc. to track the fundus of the patient and present stimuli in specific anatomically-defined locations. Furthermore, this tracking means that exactly the same locations can be tested on subsequent (follow-up) visits. The investigators will use a method called two-color perimetry to map rod and cone sensitivity on this device. With this technique, the sensitivity difference (blue-red) to chromatic test stimuli can be used to determine whether rods, cones or both photoreceptor systems mediate the threshold at a given location in the macula.
This study is aimed to characterize Russian population of Usher patients.
This study will evaluate the safety and efficacy of a recombinant adeno-associated virus vector expressing a human RPGR-ORF15 gene (rAAV2tYF-GRK1-RPGR) in patients with X-linked retinitis pigmentosa caused by RPGR-ORF15 mutations. Approximately 15 participants will be enrolled and 3 dose levels will be evaluated in a dose-escalation format.
The purpose of this study is to evaluate subjects with X-linked retinitis pigmentosa caused by RPGR-ORF15 mutations in a clinical setting to fully characterize their condition, measure testing variability, and estimate rates of progression of clinical parameters.
The objective of this study is to develop the comprehensive visual function evaluation method in severe visually impaired patient
