What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called EYE103 for diabetic macular edema (DME), a condition that causes vision problems due to diabetes. The study aims to compare the effectiveness of two different doses of EYE103 with an existing treatment, ranibizumab, an injection used for eye conditions. Participants will receive treatments every four weeks for the first year, after which the schedule will adjust based on their needs. Individuals with type 1 or type 2 diabetes who experience vision loss due to DME might be suitable for this trial. As a Phase 2, Phase 3 trial, this study is crucial for evaluating the effectiveness of EYE103 and represents the final step before FDA approval, offering participants a chance to contribute to advancing treatment options.

Will I have to stop taking my current medications?

The trial requires that you stop using drugs with known retinal toxicity, such as Hydroxychloroquine, pentosan polysulfate sodium, and amiodarone. If you have been treated for diabetic macular edema with certain medications recently, you may also need to stop those before joining the trial.

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

Research has shown that EYE103 is well-tolerated in early studies. In one study, patients with diabetic macular edema experienced promising safety results after 12 weeks of using EYE103, with no serious side effects reported. This early safety information suggests EYE103 is safe for humans. As the current trial continues, more data will help confirm these findings. ^{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 might offer a new way to manage this condition. Unlike the standard treatment, Ranibizumab, which primarily focuses on inhibiting vascular endothelial growth factor (VEGF), EYE103 may have a different mechanism of action that offers additional benefits. The trial is exploring both low and high doses of EYE103, which could provide insights into its effectiveness and potential advantages over existing treatments. This could mean more personalized and effective treatment options for patients struggling with diabetic macular edema.

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

Research has shown that EYE103, a new treatment for diabetic macular edema, appears promising in early studies. Initial results suggest that EYE103 improves vision and is well-tolerated by patients. This trial includes separate arms for both low and high doses of EYE103 to evaluate its effectiveness. In contrast, ranibizumab, compared in a separate treatment arm, is already known to improve vision for similar eye conditions. Both treatments are being carefully studied in this trial to understand their potential in managing diabetic macular edema. ^{1 3 4 6 7}

Trial Overview

The study compares two doses of a new medication called EYE103 against an established treatment, Ranibizumab, for DME. It's randomized and double-masked, meaning neither participants nor researchers know who gets which treatment. The goal is to determine the effectiveness and safety of EYE103.

Published Research Related to This Trial

Intravitreal injections of ranibizumab (Lucentis) have been shown to be an effective and safe treatment option for macular edema caused by retinal vein occlusion, which is a major cause of vision impairment.

Compared to traditional treatments like laser photocoagulation or intravitreal triamcinolone, ranibizumab offers significant improvements in managing this condition, as supported by data from randomized clinical trials.

Safety and Efficacy of Ranibizumab in Macular Edema following Retinal Vein Occlusion. Gallego-Pinazo, R., Dolz-Marco, R., Marín-Lambíes, C., et al.[2021]

The RELIGHT clinical trial demonstrated that ranibizumab treatment for diabetic macular oedema led to significant improvements in visual functioning as measured by the NEI-VFQ over 18 months, indicating its efficacy in enhancing patients' quality of life.

Despite improvements in patient satisfaction reported by the MacTSQ, there was no correlation between visual acuity and satisfaction scores, suggesting that factors influencing patient satisfaction may not be fully captured by traditional measures.

Patient-reported outcomes in the RELIGHT clinical trial of ranibizumab in diabetic macular oedema. Chakravarthy, U., Pearce, I., Banerjee, S., et al.[2022]

In a 12-month study involving patients with clinically significant diabetic macular edema, both 0.5 mg and 1.0 mg doses of ranibizumab led to significant reductions in central foveal thickness and improvements in visual acuity, with the 1.0 mg dose showing a greater average improvement of +7.9 letters compared to +3.8 letters for the 0.5 mg dose.

The study demonstrated that ranibizumab is effective in treating diabetic macular edema, with both doses resulting in positive outcomes, although the higher dose provided a more substantial improvement in visual acuity.

In two phase 3 clinical trials involving 759 patients, treatment with intravitreal ranibizumab significantly improved patient-reported vision-related function, as measured by the NEI VFQ-25 scores, compared to sham treatment at both 12 and 24 months.

The improvement in vision-related function was particularly notable in better-seeing eyes, with a mean score increase of 10.9 points at 24 months for patients receiving 0.3 mg ranibizumab in the RIDE trial, indicating its efficacy in enhancing quality of life for those with diabetic macular edema.

In a study of 30 eyes with persistent diabetic macular edema (DME) after treatment with bevacizumab, 0.3 mg ranibizumab improved visual acuity by an average of +6.5 letters over one year, indicating its efficacy as a treatment option.

Ranibizumab also led to a significant reduction in central subfield thickness, with an overall mean decrease of 116 µm, suggesting improved anatomical outcomes in patients with DME.

Ranibizumab (Lucentis®) significantly improves visual acuity in patients with macular oedema following retinal vein occlusion, as shown in two phase III trials with monthly injections leading to better outcomes than sham injections at 6 months.

The treatment was generally well tolerated, with adverse events aligning with those seen in other conditions treated with ranibizumab, indicating a favorable safety profile.

Ranibizumab treatment significantly improved diabetic retinopathy (DR) outcomes, especially in patients with moderately severe to severe nonproliferative DR, showing a 78.4% to 81.1% rate of 2-step or more improvement at 24 months compared to only 11.6% in the sham group.

Patients receiving ranibizumab had a threefold reduction in the probability of experiencing new proliferative events by month 36, indicating its efficacy in preventing disease progression in high-risk patients.

In a study of 100 patients with diabetic macular oedema, combination treatment with ranibizumab and macular LASER showed better visual and retinal thickness outcomes compared to LASER monotherapy over a two-year follow-up period.

The need for ranibizumab injections decreased significantly from an average of 3.86 in the first year to 2.02 in the second year, indicating that the treatment becomes more effective over time without serious adverse events.

In a 36-week crossover study involving 56 participants with diabetic macular edema, ranibizumab showed a statistically significant improvement in visual acuity (6.6 letters) compared to bevacizumab (5.3 letters), indicating ranibizumab may be slightly more effective for this condition.

Ranibizumab also resulted in a greater reduction in central retinal thickness (-137 μm) compared to bevacizumab (-89 μm), suggesting it may provide better structural benefits in addition to visual improvements.

Intravitreal injections of ranibizumab significantly improved visual acuity and reduced central retinal thickness in patients with macular edema due to retinal vein occlusion, with average improvements of 9 letters in visual acuity and a decrease of 195 μm in retinal thickness after each injection.

The treatment was found to be safe, with no local or systemic adverse effects reported, but further long-term studies are needed to compare its efficacy against the natural progression of the condition.
