About this study
Official title: The Effect of Subconjunctival Aflibercept on Regression of Corneal Neovascularization
The goal of this current study is to prospectively evaluate the influence of a single subconjunctival aflibercept injection on the regression of corneal neovascularization. Twenty patients with corneal neovascularization who are candidates for anti VEGF treatment (by the discretion of a corneal specialist) will be included in this study. The patients will be treated with a single subconjunctival injection of 0.08 ml aflibercept (25 mg/ml) in a single quarter of the conjunctiva, near the limbus in a proximity to the area of pathological neovascularization. Regression of neovascularization will be documented.
Read the detailed description
An interruption of the equilibrium between proangiogenic and antiangiogenic factors in the usually nonvascularized cornea causes new corneal vessels to sprout, interfering with the corneal clarity that is essential for maintaining normal vision. Treating the neovascularized and often scarred cornea remains highly challenging because the loss of immunologic privilege in the avascular cornea makes it a poor candidate for corneal transplantation.
Vascular endothelial growth factor (VEGF) is a key cytokine in the development of both normal blood vessels and vessels in tumors and other tissues undergoing abnormal angiogenesis. In the cornea, VEGF is one of several known mediators of neovascularization. In recent years, anti-VEGF compounds have been extensively investigated for use in the prevention and treatment of neovascularization in many tissues, including the cornea. Experimental models and clinical studies have reported promising results for such anti-VEGF compounds as bevacizumab (Avastin®) and ranibizumab (Lucentis®). Aflibercept is a VEGF-Trap molecule. It has the highest affinity of all VEGF blockers studied to date. Aflibercept has been approved in the United States and Europe for the treatment of macular degeneration under the trade name Eylea® and the treatment of metastatic colorectal cancer under the trade name Zaltrap®. It has been found to offer a more prolonged and potentially more potent anti-VEGF effect in wet age-related macular degeneration than both bevacizumab and ranibizumab. Aflibercept's safety has been proven for this indication.
A preliminary study in a rat model recently conducted by our group demonstrated that subconjunctival (SC) injection and topical administration of aflibercept efficiently prevented corneal neovascularization compared to bevacizumab. The aim of this present study is to determine aflibercept's efficacy in the treatment of corneal neovascularization in humans.
Goal:
To prospectively evaluate the influence of a single subconjunctival aflibercept injection on the regression of corneal neovascularization.
Design and Clinical Follow-up:
A prospective study, including patients with various corneal pathologies complicated by corneal neovascularization.
Twenty patients with corneal neovascularization who are candidates for anti VEGF treatment (by the discretion of a corneal specialist) will be included in this study. The patients will be treated with a single subconjunctival injection of 0.08 ml aflibercept (25 mg/ml) in a single quarter of the conjunctiva, near the limbus in a proximity to the area of pathological neovascularization.
During follow-up period, previous medical and ophthalmic history will be documented. On the first visit, a thorough eye examination will be performed (including: Best Corrected Visual Acuity (BCVA), slit lamp examination of anterior segment including fluorescein staining of cornea for the assessment of epithelial integrity, intraocular pressure (IOP) measurements with Goldman tonometry, and a specular microscopy examination). Follow-up examinations will occur on days 7, 14, 30, 60, 90 following injection. Each follow-up meeting will include documentation of BCVA, IOP, a slit lamp exam and specular microscopy exam. Investigators will also perform anterior segment color photography before injection and at the last visit to document regression of neovascularization.
If no improvement or partial improvement is noted on the 30th day follow-up, the cornea specialist will consider a repeat subconjunctival aflibercept injection.

What is being measured
The primary outcome is the main question the study is designed to answer.
Regression (change from baseline) of neovascularization clinically assessed by a corneal specialist
Regression of corneal neovascularization as the change from baseline will be assessed at all follow-up times on days 7,14,30,60,90 following injection by the corneal specialist, both by a clinical slit lamp exam to evaluate the area of neovascularization from the entire corneal area (which will be determined clinically by the ophthalmologist), and by performing anterior segment color photography before injection and at the last visit for comparison and documentation purposes.
Measured: 3 months (90 days), with repeat assessment at different follow up times at 7,14,30,60 and 90 days.
Secondary outcomes (1)
Best Corrected Visual Acuity (BCVA)
BCVA will be assessed using a Snellen Chart at all follow-up meetings, and converted to logMAR for statistical analysis.
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Aflibercept in people with Corneal Neovascularization, run by Rabin Medical Center at 1 site in Israel.
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 1 inclusion and 5 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: stopped early, as of the sponsor's last update on 16 Sep 2019. 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 Israel. 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 combined 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.
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 was stopped early (reason given: the treatment was found to be inefficient for all recruited patients). Results are not available in the source record.
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?
Regression (change from baseline) of neovascularization clinically assessed by a corneal specialist (time frame: 3 months (90 days), with repeat assessment at different follow up times at 7,14,30,60 and 90 days.). 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 NCT02797704, which also lists 14 linked publications.
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 16 Sep 2019.
