简要总结
The objective of this clinical study is to evaluate the safety and feasibility of focal delivery of radiation for the treatment of subfoveal choroidal neovascularization (CNV) in patients with age related macular degeneration that have failed Primary Anti-VEGF therapy.
详细描述
Therapeutic advances in the arena of neovascular age-related macular degeneration (AMD) have provided multiple treatment options for the disease. Radiotherapy 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.

入选标准
- •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 received a minimum of three (3) prior injections (a minimum of 3 prior injections of the same compound) of anti-VEGF therapy (Lucentis® or Avastin®, subjects may have been treated previously with Macugen®, but must have been most recently treated with Lucentis® or Avastin® and met the criteria for failure below) with evidence of "failure" to respond to therapy
- •Subjects must be age 50 or older
排除标准
- •Subjects with prior or subfoveal CNV therapy with photodynamic therapy, intravitreal or subretinal steroids, or transpupillary thermotherapy (TTT) (Note: This includes subjects with no known history, but with photographic evidence of prior therapy)
- •Subjects who underwent previous radiation therapy to the eye, head or neck
- •Subjects who have been previously diagnosed with Type 1 or Type 2 diabetes mellitus. Subjects who do not have a documented diagnosis but have retinal findings consistent with Type 1 or Type 2 Diabetes Mellitus.
- •Women of child-bearing potential (female subjects must be post menopausal or surgically sterilized)
结局指标
主要结局
Safety Parameters to be evaluated include incidence and severity of ocular adverse events identified by eye examinations, including visual acuity. Retinal thickness will also be measured, and stereo fundus photography will be reviewed.
时间窗: 3 Year
次要结局
- Efficacy Assessment: Preliminary efficacy will be evaluated by measuring best-corrected visual acuity (ETDRS) and AMD lesion size and leakage as assessed by fluorescein angiography at 1, 2, 3, 6, 12, 18, 24, and 36 months in the study eye.(3 Years)
