简要总结
This research project entails delivery of a personalized antisense oligonucleotide (ASO) drug designed for a single participant with Retinal Dystrophy due to PRPH2 mutation
详细描述
This is an interventional study to evaluate the safety and efficacy of treatment with an individualized antisense oligonucleotide (ASO) treatment in a single participant with Retinal Dystrophy due to PRPH2 mutation

入选标准
- •Have a clinical diagnosis of retinal dystrophy as a result of the PRPH2 variant
- •Have written informed consent (signed and dated), and able to comply with all study requirements, and any authorization required by local law
- •Be able to travel to the study site and adhere to study related follow-up examinations and/or procedures
- •Have a molecular diagnosis of a heterozygous PRPH2 variant: c.623G>A (p.Gl208Asp) based on genetic testing at Screening (a historic genetic testing report from a certified laboratory is acceptable with Sponsor/Investigator approval)
- •Have a BCVA in the worse eye of at least Count Fingers (CF) or better
- •Have clear ocular media and adequate pupillary dilation to permit good quality retinal imaging, as determined by the Investigator
- •Be a non-pregnant and non-lactating female, and either surgically sterile (e.g., ≥6 weeks post bilateral salpingectomy, bilateral oophorectomy with or without hysterectomy, tubal ligation) or post-menopausal (12 months of spontaneous amenorrhea in females >55 years of age or, in females < 55 years, have had 12 months of spontaneous amenorrhea without alternative medical cause); male participants and their female partners of childbearing potential must use appropriate contraception methods, or refrain from sexual activity for the duration of the study and for 3 months after the last study treatment; for women of childbearing potential for whom the Investigator considers that the potential benefit outweighs any risk to the unborn fetus, a highly effective method of contraception must be used
排除标准
- •There is any condition that in the opinion of the Investigator, would ultimately prevent the participant from completion of the study procedures
- •There is a present (current) active ocular infection (including herpes simplex virus, varicella zoster or cytomegalovirus) in either eye
- •There is current cystoid macular edema (CME) in the treatment eye(s); CME is permissible if stable for 3 months in the opinion of the Investigator (with or without treatment); past CME is permissible if resolved for more than 1 month
- •There are lens opacities in the eye(s) to be treated that are clinically significant in the opinion of the Investigator or that would prevent clinical and photographic evaluation of the retina
- •Receipt within 1 month prior to informed consent of any intraocular or periocular surgery, or IVT injection, or planned/anticipated intraocular surgery or procedure during the course of the study
- •There is current use of, or treatment within the past 3 months or planned treatment of drugs known to be toxic to the lens, retina or optic nerve including but not limited to systemic/intraocular steroids, amiodarone, desferriosamine/desferoxamine, chloroquine/hydroxychloroquine sulfate (Plaquenil), tamoxifen, ethambutol, phenothiazine derivatives including chlorpromazine, fluphenazine (deconoate) levomepromazine, and thioridazine; intermittent use of intraocular steroids may be considered for inclusion following approval by the Investigator
- •Any prior receipt of genetic or stem-cell therapy for ocular or non-ocular disease
- •There is any secondary or alternate genetic cause of retinal disease other than the heterozygous PRPH2 c.623G>A (p.Gly208Asp) variant
- •There has been use of any investigational drug or device within 3 months or 5 half-lives of the first treatment day (Day 1), whichever is longer, or plans to participate in another study of a drug or device during the trial period and for 3 months after the end of the trial period
- •There is presence of any significant ocular/non-ocular disease/disorder (including laboratory abnormalities) which, in the opinion of the Investigator, may put the participant at risk, or may influence the results of the trial, or impact the ability of the participant to participate in the trial
- •The intraocular pressure in the eye(s) to be treated is greater than 25 mmHg (even in the presence of glaucoma or ocular hypertension which is stabilized on therapy)
- •Prior pars plana vitrectomy in the eye(s) to be treated that may affect treatment in the opinion of the Investigator
- •Presence of any intravitreal device (e.g., steroid implant)
