Inclusion criteria

  1. Signed must be obtained prior to participation in the study.
  2. Male or female patients ≥ 19 years of age at screening
  3. Presence of active polypoidal lesions in the macular as shown by ICGA and presence of serosanguinous maculopathy (exudative or hemorrhagic features involving the macula on floor fundus photography, FA and SD-OCT AND presence of IRF or SRF that affects the central subfield as seen by SD-OCT
  4. Best-corrected visual acuity (BCVA) score between 83 and 23 letters, inclusive, using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts at both screening and baseline visit (study eye)

Exclusion criteria

Exclusion Criteria:

  1. Ocular conditions/disorders at screening or baseline which could, in the opinion of the investigator, prevent response to study treatment or may confound interpretation of study results, compromise visual acuity or require planned medical or surgical intervention during the first 12-month study period, structural damage of the fovea, atrophy or fibrosis at the center of the fovea (study eye)
  2. A history of any evidence of type 2 or type 3 neovascularization, myopic choroidal neovascularization, or other ocular disorders
  3. Total area of subretinal hemorrhage larger than 9DA or comprising ≥ 50% of the lesion area or presence of vitreous hemorrhage in study eye
  4. Any active intraocular or periocular infection or active intraocular inflammation, at screening or baseline (study eye)
  5. Uncontrolled glaucoma defined as intraocular pressure (IOP) > 25 mmHg on medication, or according to investigator's judgment, at screening or baseline (study eye)
  6. Ocular treatments: any anti-VEGF drugs, intraocular or periocular , macular laser photocoagulation or PDT, previous ocular surgery except cataract surgery (study eye)
  7. Stroke or myocardial infarction during the 6-month period prior to baseline
  8. Systemic anti-VEGF therapy at any time.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Aflibercept 8 mg

    The first loading injection will be performed for all participants. After 4 weeks, treatment response will be judged. If the polyp is completely regressed with no disease activity, injection interval will be extended to 8 weeks. The participants with presence of disease activity will continue 4-week loading injections up to 3 monthly loading dose and commence the T\&E phase thereafter. In the T\&E phase, patients have their injection interval extended or shortened by 4 weeks. The injection interval is maintained if the criteria for treatment adjustment were not met and residual fluid was decreased from the previous visit. The minimum and maximum injection intervals are 8 and 24 weeks, respectively.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
