A Study to Learn About the Blood Levels of Aflibercept When High-dose Aflibercept is Injected in Both Eyes of Participants With Diabetic Macular Edema or Neovascular Age-related Macular Degeneration
Researchers are looking for a better way to treat participants who have diabetic macular edema (DME) or neovascular age-related macular degeneration (nAMD).
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. DME is a leading cause of vision loss in working age adults. 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.
The study treatment Aflibercept (also called BAY 86-5321) is a drug that blocks a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth and leakage of blood vessels at the back of the eye.
The main purpose of this study is to to collect more information on the blood levels of aflibercept when 8 mg aflibercept is injected in both eyes of participants with DME or nAMD.
For this, the researchers will analyze Maximum observed concentration (Cmax): the highest amount of aflibercept in participants' blood will be measured after multiple doses of aflibercept during the study.
Participants will receive 8 mg aflibercept as injections into the vitreous cavity (jelly-like substance that fills the centre of the eye) of both eyes.
Participants will be divided into three groups and will receive initial and maintenance injections of 8 mg aflibercept in both eyes. Researchers will closely monitor the health of the participants during the study.
During the study, the doctors and their study team will:
* take blood and urine samples
* do physical examinations
* examine heart health using electrocardiogram (ECG)
* check vital signs such as blood pressure, heart rate, body temperature
* ask the participants questions about how they are feeling and what adverse events they are having.
An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Men or women ≥18 years of age (or country's legal age of adulthood if the legal age is \>18 years).
* Participants (treatment naïve or previously treated) requiring intravitreal anti-vascular endothelial growth factor (VEGF) treatment in both eyes in the opinion of the investigator.
* Participants with type 1 or type 2 diabetes mellitus and DME in both eyes with active central involvement (CI-DME) in at least one eye with central retinal thickness (CRT) ≥300 µm (or ≥320 µm on Spectralis) as determined by the investigator at the screening visit, OR diagnosis of nAMD in both eyes with active subfoveal choroidal neovascularization (CNV) in at least one eye with intraretinal fluid (IRF) and/or subretinal fluid (SRF) on OCT as determined by the investigator at the screening visit.
* Best corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study (ETDRS) letter score of 78 to 24 (approximate Snellen equivalent of 20/32 to 20/320) in eyes with active disease and decreased vision determined to be primarily the result of DME or nAMD.
* A female participant is eligible to participate if she is not pregnant or breastfeeding. Women of childbearing potential (WOCBP) or men who are sexually active with partners of childbearing potential must agree to use highly effective contraception prior to the initial dose/start of the first treatment, during the study, and for at least 4 months after the last administration of study intervention.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
