What side effects are associated with this type of intervention?

The most common treatments for diabetic retinopathy, particularly anti-VEGF agents such as brolucizumab, include side effects like eye pain, vitreous floaters, and increased intraocular pressure. Other potential adverse effects are inflammation inside the eye (endophthalmitis), retinal detachment, and bleeding in the eye. These treatments aim to inhibit abnormal blood vessel growth, but patients should be monitored for these side effects to manage any complications promptly.

What prior FDA approvals exist?

The FDA has approved several anti-VEGF agents for the treatment of Diabetic Retinopathy, which work by inhibiting abnormal blood vessel growth. These include Ranibizumab (Lucentis), Aflibercept (Eylea), and Bevacizumab (Avastin). These drugs have been shown to be effective in reducing vision loss and improving visual acuity in patients with Diabetic Retinopathy by targeting and inhibiting vascular endothelial growth factor (VEGF), thereby reducing abnormal blood vessel formation and leakage.

What other types of research exist?

Promising novel alternatives to Brolucizumab for Diabetic Retinopathy patients include Faricimab, a bispecific antibody targeting both VEGF and Angiopoietin-2, and KSI-301, a novel anti-VEGF biopolymer conjugate. Both have shown positive results in clinical trials and are expected to be available around 2024.

Summary

This trial is testing if brolucizumab, an eye injection that reduces swelling and stops harmful blood vessel growth, is as effective as laser treatment for patients with severe diabetic eye disease. Brolucizumab has shown excellent results for similar eye conditions.

Who is the study for?

This trial is for individuals with type 1 or 2 diabetes, an HbA1c of ≤12%, and diagnosed proliferative diabetic retinopathy (PDR) without prior laser treatment in the affected eye. Participants must have stable diabetes management for at least three months and be able to undergo retinal imaging.

What is being tested?

The study compares the effectiveness and safety of a medication called Brolucizumab against traditional laser therapy (PRP) in treating PDR. The main goal is to see if Brolucizumab can match PRP's ability to maintain or improve vision after one year.

What are the potential side effects?

Brolucizumab may cause side effects such as inflammation inside the eye, potential increase in intraocular pressure, blood vessel growth on the iris, pain or redness around the injection site, and possible impact on visual acuity.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

The most common treatments for Diabetic Retinopathy include Anti-VEGF agents like Brolucizumab, which inhibit the action of vascular endothelial growth factor (VEGF). VEGF promotes the growth of abnormal blood vessels in the retina, leading to vision loss. By blocking VEGF, these agents reduce the proliferation of these vessels, thereby preserving vision and preventing further complications. Other treatments include laser photocoagulation, which seals leaking blood vessels, and corticosteroids, which reduce inflammation and edema. These treatments are essential for managing the progression of Diabetic Retinopathy and maintaining visual function in patients.
