Study Details

Study Description

Brief Summary

Single agent anti-VEGF therapies such as ranibizumab have shown great promise and have set the standard for visual outcomes in treating wet macular degeneration. However, they need to be administered frequently by intraocular injections with the attendant risk of endophthalmitis, lens damage, retinal detachment, and vitreous hemorrhage. The purpose of this trial is to see if using photodynamic therapy in combination with ranibizumab will decrease the number of treatments with ranibizumab.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

A randomized, prospective, multicenter trial will compare two groups of patients with subfoveal choroidal neovascularization secondary to AMD. One group will receive 0.5 mg. ranibizumab intraocularly initially. This will be repeated monthly for 3 months total and then as needed over the period of one year. The other group will receive Reduced Fluence-PDT (25 Joules) followed by 0.5 mg. of ranibizumab intraocularly on the same day. The second group will receive the combination of ranibizumab and RF-PDT as needed over a period of one year. Re-treatment will be determined by the individual investigator based on visual acuity, retinal thickness as measured by optical coherence tomography (OCT), and fluorescein angiography. Visual acuity and OCT measurements will be performed by masked examiners.
