About this study
Official title: Ultra-wide Fluorescein angiograpHy to Evaluate the Progression of Retinal ischeMia After aflibErcept Injections in patientS With Central Retinal Vein Occlusion in Real Life (HERMES Study)
In patients with macular edema secondary to CRVO, Aflibercept demonstrated efficacy and safety in 2 parallel trials, interventional phase III studies, COPERNICUS study performed in United States and GALILEO study performed in Europe and Asia/Pacific.
With the project of Hermes Study, the first observational study conducted in France in patients with CRVO and treated with aflibercept, we would like to evaluate in real life the monitoring and the use of Aflibercept. The primary objective of this study will also be based on anatomic outcomes. The evolution of retinal ischemia and the degree of non-retinal perfusion will be particularly evaluated by using ultra wide field angiography technology.
Read the detailed description
The pathophysiology of Central Retinal Vein Occlusion (CRVO) is incompletely understood, but a significant slow-down in blood flow, caused by various predisposing factors, results in the release of VEGF, leading to the breakdown of the blood-retinal-barrier and finally to macular edema. The level of VEGF has been also correlated with neovascularization and vascular permeability in patients with ischemic CRVO. Several treatments have been used to treat patients with CRVO such as hemodilution, surgery, laser treatment and corticoids injection. However anti-vascular endothelial growth factor (anti-VEGF) agents administered by intravitreal injection, improve both visual and anatomic outcomes in patients with macular edema secondary to CRVO. Aflibercept is a fusion protein, use by intravitreal injection. In patients with macular edema secondary to CRVO, Aflibercept demonstrated efficacy and safety in 2 parallel trials, interventional phase III studies, COPERNICUS study performed in United States and GALILEO study performed in Europe and Asia/Pacific. In these studies, anatomic outcomes such as ischemic progression and retinal perfusion status were evaluated as secondary objectives; the primary objective of these studies was visual outcome.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In patients with macular edema secondary to CRVO, Aflibercept demonstrated efficacy and safety in 2 parallel trials, interventional phase III studies, COPERNICUS study performed in United States and GALILEO study performed in Europe and Asia/Pacific.
With the project of Hermes Study, the first observational study conducted in France in patients with CRVO and treated with aflibercept, we would like to evaluate in real life the monitoring and the use of Aflibercept. The primary objective of this study will also be based on anatomic outcomes. The evolution of retinal ischemia and the degree of non-retinal perfusion will be particularly evaluated by using ultra wide field angiography technology.

Questions about this trial
What is this clinical trial studying?
An observational study of Retinal Vein Occlusion, run by Centre Hospitalier Intercommunal Creteil at 9 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in non-perfused areas in both macula and peripheral retina at 12 months (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02880644, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2023.
