Prophylactic Ranibizumab for Exudative Age-related Macular Degeneration (PREVENT)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02140151
Recruitment Status : Completed
First Posted : May 16, 2014
Last Update Posted : August 25, 2022

Brief Summary:
This study will determine whether quarterly injections of Ranibizumab may prevent eyes with dry age-related macular degeneration from progressing to wet age-related macular degeneration (AMD).

Condition or disease Intervention/treatment Phase
Age-related Macular Degeneration Drug: Ranibizumab 0.5mg Phase 1 Phase 2

Detailed Description:

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.

Primary Outcome Measures :
  1. 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)

Secondary Outcome Measures :
  1. Vision change [ Time Frame: 2 years ]
    Change in best-corrected visual acuity (BCVA) from baseline at 12 and 24 months

  2. Vision loss [ Time Frame: 2 years ]
    Proportion of eyes losing < 5, 10, and 15 letters on EDTRS chart at 12 and 24 months

  3. Number of injections [ Time Frame: 2 years ]
    Number of injections required in eyes that convert from dry to wet AMD during the study period

  4. Baseline predictive factors [ Time Frame: 2 years ]
    Baseline demographic, genetic and ocular characteristics predictive of development of wet AMD

  5. 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).

  6. Ocular adverse events [ Time Frame: 2 years ]
    Incidence and severity of ocular adverse events, as identified by eye examination and imaging

  7. Systemic adverse events [ Time Frame: 2 years ]
    Incidence and severity of other adverse events, as identified by physical examination or subject reporting.

  • History of therapeutic radiation in the region of the study eye.
  • Presence of media opacity that would preclude adequate examination and/or imaging
  • Concurrent macular conditions that would affect the study parameters (epiretinal membrane, macular hole, macular edema) or require treatment within the duration of the study
  • Any progressive ocular condition (uncontrolled glaucoma, diabetic retinopathy, uveitis) that may affect the visual acuity for the duration of the study
  • Active ocular infection (i.e., bacterial, viral, parasitic, or fungal) in either eye at enrollment
  • Presence of any advanced systemic condition that may hinder the patients participation and completion of the study
  • Concurrent use of systemic anti-VEGF therapy
