A Real-World Evidence Study for the Incidence of Retinal Vasculitis (RV) Among Adult Patients Receiving Aflibercept 2 mg in the United States (US)

October 27, 2025 updated by: Regeneron Pharmaceuticals

Incidence of Retinal Vasculitis Among Patients Receiving Aflibercept 2 mg: A US Real-World Evidence Study Using the IRIS Registry

This study will describe and estimate the incidence of RV events among patients and patient eyes receiving aflibercept intravitreal (IVT) (Eylea® 2mg) therapy in US clinical practice. This study will also use clinical record review to confirm cases of RV first identified using International Classification of Diseases, tenth revision, Clinical Modification (ICD-10-CM) codes and to identify RV with occlusion.

Study Overview

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is purely descriptive using secondary data from the Verana Health Retinal Outcomes module sourced from the American Academy of Ophthalmology's Intelligent Research in Sight (IRIS®) Registry

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population will represent patients and patient-eyes who initiate aflibercept 2 mg injections to treat neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), diabetic retinopathy (DR) without DME, DR with macular edema (ME) status unknown, or ME following retinal vein occlusion (RVO).

Description

Key Inclusion Criteria:

  1. Patient-eyes with at least one aflibercept 2 mg injection between January 1, 2017 and June 30, 2023
  2. Patient-eyes with at least one aflibercept 2 mg injection with a specified laterality. The earliest date of aflibercept injection will be the index date for each patient-eye
  3. Patient-eyes with diagnosis (documented through ICD-10-CM diagnosis code) of nAMD, DME, DR without DME, DR with ME status unknown, and/or ME following RVO in the same eye as the aflibercept injection within 14 days prior to the index date (inclusive)

Key Exclusion Criteria:

  1. Patients with aflibercept 2 mg injection within 12 months (365 days) prior to the index date (not inclusive) will be excluded, as defined in the protocol
  2. Patient-eyes with a diagnosis of RV in the same eye as the aflibercept injection or with unspecified laterality within 12 months (365 days) prior to index date (inclusive), as defined in the protocol
  3. Aflibercept treatment episodes (aflibercept injections) with unspecified laterality, ophthalmic procedures or surgeries within 60 days prior to the injection date

NOTE: Other protocol defined inclusion/exclusion criteria may apply

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Time Frame: During the 60-Day at-risk period following aflibercept 2 mg IVT, up to approximately 6.5 years
During the 60-Day at-risk period following aflibercept 2 mg IVT, up to approximately 6.5 years
Incidence of occlusive RV events confirmed through clinical chart abstraction
Time Frame: During the 60-Day at-risk period following aflibercept 2 mg IVT, up to approximately 6.5 years

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
