About this study
Official title: Comparison of Early Intervention of PDT Combination With Ranibizumab vs. Ranibizumab Monotherapy in Persistent PCV Patients With Initial Loading Dose
The aim of this study is to compare the efficacy of early intervention of PDT combination compared with consecutive monthly treatment of intravitreal ranibizumab injections in PCV patients showing insufficient response with initial loading dose.
Read the detailed description
PCV is generally recognized as a subtype of wet AMD characterized by the presence of aneurysmal orange-red polypoidal lesions with or without branching vascular network (BVN) in the choroidal vasculature as observed on indocyanine angiography (ICGA), representing 13% to 54.7% of newly diagnosed patients with neovascular AMD. Fifty percent of PCV had persistent leakage or recurrent bleeding with poor visual outcome, if left untreated.
And in the EVEREST study has shown that synergistic effects of anti-VEGF and vPDT combination: vPDT strongly regress polyp and anti-VEGF control to up-regulation of VEGF induced by vPDT compared to ranibizumab monotherapy in newly diagnosed PCV patients. Additionally, combination offers an opportunity for individualized treatment with potentially fewer treatments and less costs.
Therefore, the aim of this study is to compare the efficacy of early intervention of PDT combination compared with consecutive monthly treatment of intravitreal ranibizumab injections in PCV patients showing insufficient response with initial loading dose.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing PDT, Ranibizumab and ranibizumab PRN in people with Age-related Macular Degeneration, run by Seoul National University Hospital.
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 5 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 12 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.
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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jangwon Heo, MD (82-2-2072-2438, hjw68@snu.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in central retinal thickness (time frame: after 6month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02864472, which also lists 1 linked publication.
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 12 Aug 2016; AzTrials last refreshed its copy on 8 Nov 2026.
