What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment, EYE103, to determine its effectiveness for people with blurry vision caused by diabetic macular edema (DME), a condition where fluid accumulates in the eye due to diabetes. Participants will receive one of two doses of EYE103 or an existing treatment, ranibizumab (an injection for eye conditions), to compare their effects. The study aims to identify which treatment is most effective and safest for improving vision. People with type 1 or type 2 diabetes who have vision problems primarily due to DME might be suitable candidates for this trial.

As a Phase 2, Phase 3 trial, this research measures the treatment's effectiveness in an initial, smaller group and represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking advancements in eye care.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot participate if you are using drugs with known retinal toxicity or have had certain eye treatments recently. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that EYE103 appears safe for treating diabetic macular edema (DME). One study found that EYE103 improved vision and was generally well-tolerated, with most participants experiencing no serious side effects. Some individuals might experience mild reactions, such as eye irritation, but current data suggests the treatment is safe.

Ranibizumab, the other treatment in this study, has already received approval for DME and is known for its safety, having been widely used with few safety concerns. Researchers are carefully comparing both treatments to determine which is safer and more effective for people with DME. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about EYE103 for diabetic macular edema because it offers a potential new approach to treatment with its unique mechanism of action. Most current treatments, like Ranibizumab, target and inhibit VEGF (vascular endothelial growth factor) to reduce fluid leakage and swelling in the eye. EYE103, however, brings a fresh angle by potentially working through a different biological pathway, which could offer enhanced efficacy or benefits for patients who do not respond optimally to existing therapies. Additionally, EYE103 is being tested in both low and high dose forms, providing flexibility in tailoring treatment to patient needs. This new approach could lead to improved outcomes and more personalized care for individuals with this condition.

What evidence suggests that this trial's treatments could be effective for diabetic macular edema?

Research shows that EYE103, also known as Restoret, could be a helpful treatment for diabetic macular edema (DME). Participants in this trial will receive either a low or high dose of EYE103. Earlier studies showed that EYE103 improved vision clarity and reduced eye swelling in patients with DME. These findings suggest that EYE103 helps manage the condition by addressing key symptoms. Additionally, the treatment was well-tolerated, with patients not experiencing major side effects. While more information is needed to confirm these benefits, the initial results are promising. ^{2 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• EYE103
• Ranibizumab

Trial Overview

The study compares two doses of a medication called EYE103 against Ranibizumab, which is already used for DME. Patients will be randomly assigned to one of three groups and treated regularly, with treatment frequency adjusted in the second year.

Published Research Related to This Trial

A patient treated with ranibizumab for diabetic macular edema experienced severe ocular complications, including anterior ischemic optic neuropathy (AION) and central retinal artery occlusion (CRAO), after multiple injections over 12 months.

Despite initial improvements in visual acuity and retinal thickness, the patient suffered significant vision loss and vascular complications, highlighting the need for careful monitoring of patients receiving intraocular anti-VEGF treatments.

Sequential anterior ischemic optic neuropathy and central retinal artery and vein occlusion after ranibizumab for diabetic macular edema. Battaglia Parodi, M., Iacono, P., Cascavilla, ML., et al.[2019]

In a 36-month study involving 290 patients with diabetic macular edema (DME), ranibizumab 0.5 mg demonstrated a mean improvement of 7.4 letters in best-corrected visual acuity (BCVA) after 12 months, indicating its effectiveness in treating visual impairment.

The study found that patients received an average of 5.1 injections over 10.4 visits, which is fewer than what is typically reported in clinical trials, while no new safety concerns were identified, supporting the treatment's safety in real-world settings.

In a study involving 5,781 patients over 24 months, intravitreal ranibizumab injections for treating eye conditions showed that 79.7% of patients reported no adverse events (AEs), indicating a generally favorable safety profile.

While 2,687 AEs were reported, with 30.3% classified as serious, the overall rate of AEs decreased over time, and no new safety concerns were identified, suggesting that ranibizumab is a safe option for patients under real-world conditions.

In a pooled analysis of safety data from 5 clinical trials involving 4,347 patients with neovascular age-related macular degeneration (nAMD), it was found that patients aged 85 years and older had a higher incidence of systemic serious adverse events (SAEs) compared to those younger than 85, indicating that age is a significant risk factor.

Despite the increased risk of SAEs in older patients, the use of ranibizumab did not significantly elevate the risk of most systemic SAEs, suggesting that the treatment is generally safe for elderly patients, although the analysis was limited by the small number of events for certain outcomes.
