What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EYLEA (Aflibercept) intravitreal injectionDrug
Intravitreal Injection once every 8 weeks with 3 initial monthly doses
| Study group | Role | What they receive |
|---|---|---|
| IVT injection once every 8 weeks after 3 initial monthly doses | Other | Intravitreal aflibercept injection 2.0mg dosed every 4 weeks (monthly)for the first 3 months followed by 2.0 mg (0.05mL) via intravitreal injection every eight weeks (2 months).
Dosing at monthly intervals is allowed if needed in the opinion of the investigator based on presence of fluid on OCT and/or a decrease in visual acuity of greater than or equal to 5 letters from the previous visit. Receives: Drug: EYLEA (Aflibercept) intravitreal injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Safety
The Incidence \& Severity will be assessed during study participation. Baseline medical conditions \& abnormal findings present prior to the patient signing the Informed Consent Form (ICF)will be recorded as pre-existing illnesses in the medical history. Clinical study staff will start assessing subjects for adverse events once the ICF has been signed starting at month 1 and at each monthly visit,and will be instructed to request the adverse event information in a nonspecific, non-suggestive type of questioning. The Investigators will record all adverse events regardless of causality.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing EYLEA (Aflibercept) intravitreal injection in people with Choroidal Neovascularization and Presumed Ocular Histoplasmosis, run by Retina Research Institute, LLC at 3 sites in United States.
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 23 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 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Safety (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 Aug 2018; AzTrials last refreshed its copy on 8 Nov 2026.
