Brief Summary

The purpose of this study is to evaluate the safety and clinical feasibility of the IRay System for the treatment of wet age-related macular degeneration (AMD).

Detailed Description

The primary objective is to evaluate the safety and clinical feasibility of stereotactic radiotherapy with the Oraya IRay system for the treatment of choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD), as measured by incidence and severity of ocular radiation related serious adverse events (SAE) and adverse events (AE) in subjects treated with an 11, 16 or 24 Gray (Gy) macular dose through the 60-month follow-up visit.

Inclusion Criteria
  • Subjects must be age 50 or older
  • Women must be post-menopausal ≥1 year or surgically sterilized
  • Subjects must have choroidal neovascularization lesion size of ≤11 total disc areas (28.26mm), and a greatest linear dimension of ≤6 mm
  • Subjects must have Early Treatment Diabetic Retinopathy Study (ETDRS) best corrected visual acuity of 69 to 24 letters (20/40 to 20/320 Snellen Equivalent) in the study eye
  • Subretinal hemorrhage (if any) must not comprise more than 50% of total lesion size, and may not involve the subfoveal space
Exclusion Criteria
  • Subjects with prior or concurrent therapies including submacular surgery, thermal laser photocoagulation (with or without photographic evidence), photodynamic therapy and transpupillary thermotherapy (TTT)
  • Subjects with concomitant disease in the study eye, including uveitis, diabetic retinopathy,presence of RPE tears or rips, acute ocular or periocular infection
  • Subjects with advanced glaucoma (>0.8 cup to disk ratio) or intraocular pressure ≥30 mmHg in the study eye
  • Previous glaucoma filtering surgery in the study eye
  • Refractive error in the study eye demonstrating more than -8 diopters of myopia (or globe axial length ≥26 mm). For subjects who have undergone prior refractive or cataract surgery in the study eye, the preoperative refractive error cannot exceed -8 diopters of myopia
  • Subjects with any retinal vasculopathies, including diabetic retinopathy, retinal vein occlusions, etc. in the study eye
