Plain-language summary
The purpose of the study is to test the investigational drug Gamunex-C on the growth of blood vessels over the cornea. This study is being conducted by Dr. Balamurali Ambati at the Moran Eye Center at the University of Utah.
The cornea is the clear outer front part of the eye. In corneal neovascularization, blood vessels grow over the cornea. Corneal neovascularization and ocular anterior segment inflammations are sight-threatening conditions. Lipid deposition and edema with subsequent scar formation can compromise corneal clarity irreversibly. Corneal neovascularization is also a well recognized risk factor for corneal graft failure. In its natural state, the cornea is a site of immune privilege well suited to tissue transplantation. Once vascularized, there is direct exposure of corneal antigens to circulating host immune mechanisms greatly increasing the chance of rejection \[Collaborative Corneal Transplantation Study\].
Melting or inflammation in the anterior chamber, cornea, or ocular surface can cause irreversible scarring or destruction of the optical elements of the eye, which can compromise vision.
Current standard of care for such conditions includes use of topical steroids and sometimes immunosuppressants (e.g., cyclosporine). These do not address a common underlying corneal neovascularization or melting.
This is a Phase 1 clinical trial of subconjunctival IVIg (Gamunex-C) injection for treatment of corneal neovascularization in the setting of corneal transplantation with neovascularization. Candidates for corneal transplantation with corneal neovascularization in one or more quadrants crossing more than 0.5mm over the limbus will be identified for inclusion in our study.

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.
. Patients receiving antiangiogenic anti-VEGF medication either systemically or intravitreally for other pathology or who have received these drugs within 3 months of study enrollment
. Patients with active corneal infection requiring additional treatment modalities
