This is an observational study in which only data are collected from people who have already been prescribed aflibercept 8 mg by their own doctors.

In this study, data from adults with visual impairment due to neovascular age-related macular degeneration (nAMD) or diabetic macula edema (DME) will be collected and studied.

Visual impairment is any degree of vision loss that affects a person's ability to perform daily activities. nAMD is an eye disorder that causes vision loss due to the growth of abnormal blood vessels that leak blood or retinal fluid into the macula (the central part of the retina). nAMD is a leading cause of vision loss for people aged 50 and older. DME is a diabetes-related eye disorder. In DME, the macula swells up due to fluid leakage from damaged blood vessels, resulting in vision problems.

Aflibercept 8 mg is a drug that is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth and leakage of blood vessels at the back of the eye.

Aflibercept 8 mg has been submitted for approval for the treatment of visual impairment due to nAMD and DME based on the results from 2 studies called PHOTON and PULSAR. This study will begin once approval is obtained. Currently, no real-world data are available for aflibercept 8 mg.

The main purpose of this study is to collect more information about how well aflibercept 8 mg injection works in people with nAMD and DME. This study will include participants who have not received any prior treatment for nAMD or DME and participants who have.

The main information that researchers will collect:

the change in vision test scores called the best corrected visual acuity (BCVA) after 12 months of treatment.

Data will be collected from February 2024 to September 2027 and will cover a period of up to 24 months per participant. The data will be collected using medical records and by interviewing the patients during regular visits that take place in routine practice.

Researchers will observe participants from the first injection of aflibercept 8 mg until the end of the observation.

In this study, only available data from regular visits will be collected. No visits or tests are required as part of this study.

SPECTRUM will be performed in eye clinics and ophthalmology practices in several countries across North America, Europe, Middle East, and Asia Pacific.

Female and male patients (aged ≥ 18 years for the DME cohorts or ≥ 50 years for the nAMD cohorts) with a diagnosis of nAMD or DME can be enrolled after the decision for treatment with aflibercept 8 mg has been made by the treating physician. Indications, contraindications, risks, warnings, and precautions according to the local market authorization/local product information should be carefully considered.

For each patient a single eye will be considered as a study eye. The eye treated with aflibercept 8 mg will be considered as study eye. If treatment for both eyes is decided simultaneously, the study eye will be the worse eye as per discretion of the treating physician. Treatment of the 2nd eye will be considered as a concomitant treatment.

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014. Interested researchers can use www.vivli.org to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research.
