  • Percentage of subjects losing less than 15 ETDRS letters [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Safety Assessment: Incidence and severity of averse events and ocular AEs. Incidence of cataract changes. Incidence of radiation induced toxicity [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

  • Mean change in ETDRS visual acuity [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Change in total lesion size and CNV size by fluorescein angiography [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Foveal thickness measured using OCT. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: A
NeoVista Ophthalmic System procedure + Lucentis
Device: NeoVista Ophthalmic System
A single procedure with the NeoVista Ophthalmic System, with Lucentis (0.5mg) administered on an as needed basis for three years.

Detailed Description:
Therapeutic advances in the arena of neovascular age-related macular degeneration (AMD) have provided multiple treatment options for the disease. Brachytherapy has been studied in multiple clinical trials in the past with many studies showing a therapeutic benefit. Treatment with radiotherapy and anti-VEGF compounds is a promising approach to treating AMD. The current treatment for neovascualar AMD involves multiple injections over an indefinite period of time. This trial will evaluate whether treatment with brachytherapy can reduce or eliminate the need for continued injections.

Ages Eligible for Study:   50 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects must have predominantly classic, minimally classic, or occult with no classic lesions, as determined by the Investigator, secondary to AMD, with a total lesion size (including blood, scarring, and neovascularization) of < 12 total disc areas (21.24 mm2) and a GLD ≤5.4 mm.
  • Subjects must have completed anti-VEGF induction treatment, defined as the first 3 months of treatment. Following the induction period, subjects must have required at least 5 additional injections of Avastin or Lucentis in the 12 months preceding enrollment, or 3 additional injections of Avastin or Lucentis in the 6 months preceding enrollment, given on an as needed basis. Subjects may have previously received Macugen, although must meet the criteria above for Lucentis or Avastin.
  • Subjects must be age 50 or older

Exclusion Criteria:

  • Subjects with prior or concurrent subfoveal CNV therapy with agents, surgery or devices (excluding Macugen, Avastin, or Lucentis) including thermal laser photocoagulation (with or without photographic evidence), photodynamic therapy, intravitreal or subretinal steroids, and transpupillary thermotherapy (TTT)
  • Subjects who underwent previous radiation therapy to the eye, head or neck
  • Subjects who have been previously diagnosed with Type I or Type II Diabetes Mellitus. Subjects that DO NOT have a documented diagnosis, but have retinal findings consistent with Type I or Type II Diabetes Mellitus.
