Interval of Disease Inactivity After Complete Polypoidal Regression in PCV Receiving Aflibercept

Thailand80 participantsStarted 2020-11-01

Plain-language summary

Polypoidal choroidal vasculopathy (PCV), a subtype of neovascular age-related macular degeneration (NV AMD), is an important cause of central visual loss, especially among Asian and African descendants. PCV is characterized by the presence of hyperfluorescent polypoidal lesions, with or without branching vascular network, identified on indocyanine green angiography (ICGA), currently the gold standard for PCV diagnosis. In addition to visual improvement from baseline, polypoidal regression or complete disappearance of polypoidal lesions on ICGA has been considered an important treatment outcome in large PCV trials including the PLANET1 and EVEREST II2 studies. Rate of polypoidal regression following intravitreous aflibercept monotherapy was 33% in the PLANET study1 year 2 and ranged between 55% to 78% in other Asian cohorts.3-4 Recently, our previous investigation5 on the timing of polypoidal regression following a fixed-dosing aflibercept monotherapy (3 initial monthly injections, then q 8 weeks until 1 year) in 40 Thai PCV eyes suggested that, among 22 eyes (55%) with polypoidal regression at 1 year, a majority of them showed complete polypoidal regression before 6 months (median duration of complete regression: 3 months (IQR, 2 months to 6 months). However, due to the fixed-dosing regimen used in previous study, there are limited data on how often polypoidal lesions remain regressed on ICGA when the treatment is deferred in eyes with polypoidal regression, nor what changes might be seen subsequently on OCT when treatment is deferred in this situation. Therefore, this study aims to determine the changes seen on OCT subsequent to complete regression of polypoidal lesions on ICGA in PCV eyes following intravitreous aflibercept treatment. Results from this study may provide some insights on longer-term PCV management

Inclusion Criteria: * Age of ≥18 years * Diagnosis of treatment-naïve PCV in either eye * PCV is defined according to the following criteria Presence of focal subretinal ICGA hyperfluorescence within the first 6 minutes, plus one of the followings; 1) subretinal orange nodule corresponds to hyperfluorescent nodule on ICGA, 2) massive submacular hemorrhage of 4 disc area or larger, 3) nodular appearance on stereoscopic viewing, 4) pulsatile polypoidal lesion, 5) abnormal vascular channel supplying the polypoidal lesion, 6) hypofluorescent halo around the nodule6 * If any participant presents with bilateral PCV in which both eyes are eligible for the study, the eye with worse vision will be chosen as the study eye Exclusion Criteria: * Presence of co-existing vision threatening conditions in the study eye, e.g., diabetic retinopathy, or retinal vascular occlusion * Presence of ocular or periocular infections, active intraocular inflammation, or known hypersensitivity to aflibercept or any of the excipients in aflibercept * Inability to obtain good quality imaging due to ocular media abnormalities * Contraindicate for FFA or ICGA due to the following conditions: * Allergic to fluorescein or indocyanine green dye * Allergic to iodine or seafood * Impaired kidney or liver functions * Not able to follow up according to the study protocol

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.
