The IAI-OCTA Study; a Study of OCT-Angiography Analysis Efficacy
a study on Macular Degeneration
A study investigating the ability of OCTA imaging technology to identify and analyze untreated type 1, 2, and 3 neovascular membrane lesions in treatment naive patients with exudative macular degeneration, as well as investigating the ability of the OCTA imaging technology to evaluate the treatment outcomes of Intravitreal Aflibercept Injection in neovascular lesions associated with macular degeneration. This study is utilizing a new, FDA approved, non-standard of care technology (OCT-Angiography by Optovue) to image and evaluate the treatment outcomes of using standard of care Intravitreal Aflibercept Injections for their approved use in patients diagnosed with neovascular AMD who are naive to previous Anti-VEGF therapies.
The IAI-OCTA Study or; Microvascular Structure and Morphology of Neovascular Membranes in Age Related Macular Degeneration (AMD) After Intravitreal Aflibercept Injection (IAI) Therapy Using OCT-Angiography Analysis
Prospective study of neovascular AMD subjects with type 1, 2, or 3 neovascularization that have not been treated with prior anti-VEGF therapy. Subjects will be scheduled for intravitreal aflibercept injection (IAI) at baseline, week 4, week 8, week 16, week 24, week 36, and week 48. Additional injections can be administered during the remaining visits on an as needed basis per PI discretion based on the presence of any intraretinal or subretinal fluid on OCT, heme visualized on examination, reduction of BCVA by 5 or more ETDRS letters, or evidence of either increased area, density, or activity of the brush border of the neovascularization on OCT angiography. There will be a minimum of 21 days between subsequent injections. Each subject will therefore receive a minimum of 7 injections and up to a maximum of 13 injections throughout the study period. No injection will be given on the exit visit, week 52. OCT angiography and spectral domain OCT imaging will be performed at baseline and every 4 weeks thereafter The above procedures are standard of care for neovascular AMD subjects. As part of this study, these subjects will also undergo imaging of both eyes with OCTA at each visit. This is not standard of Care and is research. The only procedure that is being performed for research is the OCT-A. The injections and all other procedure are SOC based on physician discretion and clinical need. The investigators will not be modifying the dosage amounts or frequency. A subgroup of willing subjects will undergo OCT angiography every 2 weeks for the first 12 weeks. Indocyanine green angiography will be performed at baseline for all subjects to establish baseline subject population characteristics. Fluorescein angiography will be performed at baseline, week 12, and week 52 for efficacy monitoring. Detailed OCT angiography analysis will be performed to identify anatomical and morphological biomarkers of growth progression and disease activity. In addition to qualitative structural and morphological analysis, detailed quantitative OCT angiography analysis of the neovascular lesion using automated or manual capillary density maps and area calculation will be performed at each visit to determine the detailed microvascular response of neovascular complexes to IAI therapy.
