AAV5-hRKp.RPGR 治疗日本 X 连锁色素性视网膜炎参与者的研究
评估 AAV5-hRKp.RPGR 治疗与色素性视网膜炎 GTP 酶调节因子 (RPGR) 致病变异相关的日本 X 连锁色素性视网膜炎的安全性和有效性的 3 期研究
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).

描述
Inclusion Criteria:
- Participants who are Japanese male or female aged 5 years or older
- Participants diagnosed as X-linked retinitis pigmentosa (XLRP) (generalized rod-cone dystrophy) associated with pathogenic or likely pathogenic variants in the retinitis pigmentosa guanosine triphosphatase regulator(RPGR) gene
- Has evidence of preserved retinal function as defined by a mean retinal sensitivity of greater than or equal to (>=) 2 decibel (dB) by Octopus static perimetry and evidence of preserved outer retinal structure (namely the presence of discernible ellipsoid zone) as determined by spectral domain-optical coherence tomography (SD-OCT) in both eyes
- Otherwise, healthy participant on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel or hematology outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
Exclusion Criteria:
- Has had ocular surgery within 3 months prior to screening or is anticipated to require ocular surgery within 6 months after the AAV5-hRKp.RPGR administration
- Is unable to perform the imaging assessments as required (for example: reliable static perimetry [reliability factor less than or equal to {<=}19], optical coherence tomography [OCT], or fundus autofluorescence [FAF]).
- Any investigational ocular treatment or any other ocular treatment that could confound the interpretation of the efficacy results or affect participant compliance with the visit schedule

干预/治疗 |
|---|---|
|
实验性的:Group 1: AAV5-hRKp.RPGR Low Dose
Participants will receive bilateral subretinal administration of AAV5-hRKp.RPGR low dose, with surgical delivery to the 2 eyes performed within 7 to 21 days apart. |
AAV5-hRKp.RPGR will be administered by subretinal injection using a standardized surgical procedure. |
|
实验性的:Group 2: AAV5-hRKp.RPGR High Dose
Participants will receive bilateral subretinal administration of AAV5 hRKp.RPGR high dose, with surgical delivery to the 2 eyes performed within 7 to 21 days apart. |
AAV5-hRKp.RPGR will be administered by subretinal injection using a standardized surgical procedure. |
