What is the purpose of this trial?

This trial tests whether infliximab, an anti-inflammatory medication, can be safely used as eye drops after cornea surgery to prevent glaucoma, a common complication. Participants will be divided into two groups: one using infliximab eye drops and the other following the standard post-surgery routine without the drops. This trial suits those undergoing their first cornea transplant who can manage eye medication or have assistance. As a Phase 1, Phase 2 trial, it aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group, offering participants a chance to contribute to groundbreaking research.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have used anti-TNF-α medication or other anti-inflammatory biologics before.

Is there any evidence suggesting that topical infliximab is likely to be safe for humans?

Research shows that topical infliximab, a drug that reduces inflammation, is being tested for safety and effectiveness in treating eye conditions. Some studies have examined its use in eye surgeries, and so far, no major safety issues have emerged.

For example, one study examined its use after glaucoma surgery and found it reduced unwanted healing without causing significant side effects. Another study is investigating its potential to prevent glaucoma after cornea surgery. Although the full results aren't available yet, no major safety concerns have been reported.

Since this is an early trial, researchers continue to monitor for any side effects. However, studies so far suggest it is generally safe when used on the eye. If considering joining a trial, this information might help you feel more comfortable about the treatment's safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for glaucoma?

Unlike the standard treatments for glaucoma, which typically include eye drops to reduce intraocular pressure or surgical procedures, topical infliximab offers a novel approach by targeting inflammation directly on the eye's surface. Infliximab is a monoclonal antibody that blocks tumor necrosis factor-alpha (TNF-alpha), a key player in the inflammatory process that can contribute to tissue damage. Researchers are excited about this treatment because it uses a topical delivery method, potentially offering fewer systemic side effects compared to traditional oral or injectable forms of infliximab. This new approach could provide an effective option for patients who undergo PKP surgery and need to manage post-operative inflammation.

What evidence suggests that topical infliximab might be an effective treatment for glaucoma?

Research has shown that infliximab eye drops might help prevent inflammation-related problems after cornea surgery. In this trial, some participants will receive topical infliximab following PKP surgery to evaluate its effectiveness in reducing the body's wound healing response in the eye, which is crucial for managing the risk of glaucoma after surgery. Although another study found that infliximab did not improve outcomes in a specific type of glaucoma surgery, it still demonstrated promise in controlling inflammation. This suggests that infliximab eye drops could lower the chance of developing glaucoma by managing inflammation after surgery. Overall, they show potential as a treatment for inflammation-related eye issues. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Topical Infliximab

Trial Overview The study aims to test if using infliximab eye drops after corneal transplant surgery is safe and can prevent glaucoma. Participants will either receive the topical infliximab drops or no treatment as a comparison. The main focus is on safety and effectiveness in preventing inflammation that could lead to glaucoma.

How Is the Trial Designed?

Group I: Topical infliximab following PKP surgery Experimental Treatment 1 Intervention

Additionally to standard post-operative regimen, patients who will be undergoing their first PKP surgery and who meet all inclusion and no exclusion criteria will be included in the experimental group. These patients will administer topical infliximab four times per day for 3 months.

Group II: No topical infliximab following PKP surgery Active Control 1 Intervention

Patients who will be undergoing their first PKP surgery, but who are not qualified to receive infliximab or who refuse to receive infliximab, will be included in the control group. These patients will only administer the standard post-operative regimen following their PKP surgery and will not administer topical infliximab. They will be followed with the same follow-up schedule, questionnaires, examinations and non-invasive tests (excluding lab work) as patients in the interventional group.

Published Research Related to This Trial

In a study of 82 pediatric patients receiving infliximab (IFX) for rheumatologic and ocular inflammatory diseases, infusion reactions (IR) occurred in 17% of patients, with the majority being mild to moderate in severity.

Despite experiencing IR, over 50% of patients were able to continue treatment with IFX by using premedication strategies such as antihistamines and corticosteroids, indicating a manageable safety profile for ongoing therapy.

Infliximab, an anti-TNF-alpha monoclonal antibody, was studied in 771 patients for Crohn's disease and rheumatoid arthritis, showing an acceptable safety profile with only 17% experiencing acute infusion reactions compared to 7% in the placebo group.

While infliximab was associated with a higher overall rate of infections (26% vs. 16% for placebo), there was no increased risk of serious infections or difference in mortality rates, indicating it is generally safe for use.

A 26-year-old female with ulcerative colitis experienced resolution of infusion-related hypersensitivity reactions after switching from the original infliximab to the biosimilar infliximab-dyyb, indicating that the biosimilar may be a safer option for some patients.

The case highlights the importance of recognizing differences in inactive ingredients between biologics, as these may contribute to adverse reactions, suggesting that switching to a biosimilar could be beneficial for patients with such sensitivities.

TNF-α blockers, particularly infliximab, show promise in treating eye conditions like diabetic macular edema and age-related macular degeneration, but their safety for intravitreal use is concerning due to reported inflammatory responses.

Current data suggests that while TNF-α blockers are effective for inflammatory diseases, their application in ophthalmology as an off-label treatment for noninfectious uveitis raises safety issues, necessitating further studies on dosing and alternative formulations.

In a study of 25 patients with refractory uveitis-related macular edema, both infliximab and adalimumab showed similar efficacy in reducing central foveal thickness over 6 and 24 months, with no significant differences between the two treatments.

At the 6-month mark, 50% of patients on adalimumab and 61% on infliximab responded to treatment, indicating that both medications are effective options for managing this condition.

Infliximab, an anti-tumor necrosis factor alpha medication, successfully suppressed inflammation in five cases of orbital inflammatory diseases and chronic relapsing inflammatory optic neuropathy that were unresponsive to other treatments.

While infliximab provided relief from symptoms and signs of inflammation, the effects were not permanent, as symptoms returned around week 5, indicating it may be a valuable alternative to steroids for managing refractory inflammation.

Infliximab can be safely injected into the eye of rabbits at doses up to 1.7 mg, with no significant ocular side effects observed in clinical examinations or electroretinography tests.

At a higher dose of 3.3 mg, some rabbits showed nerve fiber edema, indicating that while lower doses are safe, higher doses may pose risks, suggesting careful dose management is necessary for potential human applications.

In a study of 177 patients with refractory uveitis due to Behçet's disease, both infliximab (IFX) and adalimumab (ADA) were effective treatments, but ADA showed significantly better outcomes in anterior chamber inflammation, vitritis, and best-corrected visual acuity after one year.

The retention rate for ADA was higher than for IFX (95.24% vs. 84.95%), suggesting that patients may prefer ADA as a first-line biologic treatment for this condition.
