About this study
Official title: Phase II Study Evaluating the Efficacy of Aflibercept for the Treatment of Iodiopathic Choroidal Neovascularization in Young Patients
After myopia, the second etiology of choroidal neovascularization (CNV) in young adults (<50 years old) is idiopathic choroidal neovascularization (ICNV) whose etiology remains unknown. This is a rare and severe disease, which can lead to blindness.
ICNV is treated at the moment with off-label anti-VEGF (Vascular Endothelial Growth Factor) therapy and could also benefit from aflibercept (EYLEA), a new anti-VEGF currently indicated in Age-related Macular Degeneration (AMD). Case reports suggest that such patients would not need as many injections as in AMD.
INTUITION is an open-label, single arm, prospective, multicenter, phase II study. The main objective is to demonstrate the effectiveness in clinical terms after 52 weeks of treatment with aflibercept on the visual acuity of patients affected by ICNV. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. Intravitreal injections of aflibercept are initiated with a Treat \& Extend (TAE) regimen until 20 weeks (3 mandatory injections with reinjection only in case of CNV activity). Then, a pro re nata (PRN) regimen is considered until 52 weeks (reinjection in case of CNV activity).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
afliberceptDrug
The patients are followed on a monthly basis until 52 weeks. Intravitreal injections of aflibercept at a dosage of 2 mg are initiated with a TAE regimen until 20 weeks (3 mandatory injections at inclusion, week 8 and 20 with reinjection at week 4, 12 and 16 only in case of CNV activity). Then, a PRN regimen is considered until 52 weeks (reinjection in case of CNV activity). Therefore, each patient receives between 3 and 13 injections in the whole study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing aflibercept in people with Idiopathic Choroidal Neovascularization, run by Hospices Civils de Lyon at 1 site in France.
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 25 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 8 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Mean change in best-corrected visual acuity (BCVA) expressed as number of letters gained or lost measured with Early Treatment Diabetic Retinopathy Study (ETDRS) scale from baseline to week 52 (time frame: 52 weeks). 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 NCT02257502, 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 8 Aug 2025.
