Age-related Macular Degeneration | Drug: Ranibizumab 0.5mg | Phase 1 Phase 2 |
This is a multicenter, prospectively randomized, masked and controlled, interventional investigator sponsored phase I/II study of subjects with high-risk nonexudative age-related macular degeneration (AMD) treated with intravitreal ranibizumab quarterly for prophylaxis of conversion to exudative age-related macular degeneration.
The objective of this study is to investigate the safety and efficacy of prophylactic anti-vascular endothelial growth factor (VEGF) therapy with ranibizumab to prevent the development of exudative AMD in eyes with high-risk nonexudative AMD. In addition, baseline characteristics of high-risk eyes (fundus features, optical coherence tomography (OCT) parameters and genetic profile) will be evaluated to determine their predictive value in conversion to exudative AMD. The effect of ranibizumab on the atrophic component of AMD will also be monitored.

- Development of exudative AMD [ Time Frame: 2 years ]Development of choroidal neovascularization (conversion) defined by the presence of leakage on fluorescein angiography (FA) and fluid within or below the retina or below the retinal pigment epithelium seen on spectral-domain optical coherence tomography (SD-OCT)
- Vision change [ Time Frame: 2 years ]Change in best-corrected visual acuity (BCVA) from baseline at 12 and 24 months
- Vision loss [ Time Frame: 2 years ]Proportion of eyes losing < 5, 10, and 15 letters on EDTRS chart at 12 and 24 months
- Number of injections [ Time Frame: 2 years ]Number of injections required in eyes that convert from dry to wet AMD during the study period
- Baseline predictive factors [ Time Frame: 2 years ]Baseline demographic, genetic and ocular characteristics predictive of development of wet AMD
- Development of geographic atrophy (GA) [ Time Frame: 2 years ]Development of geographic atrophy (GA) as detected by fundus photography (FP) and/or fundus autofluorescence (AF).
- Ocular adverse events [ Time Frame: 2 years ]Incidence and severity of ocular adverse events, as identified by eye examination and imaging
- Systemic adverse events [ Time Frame: 2 years ]Incidence and severity of other adverse events, as identified by physical examination or subject reporting.
