A new biosimilar of Eylea, a brand-name form of aflibercept, is now available in the United States. Biosimilars are medications that are highly similar to FDA-approved biologic drugs, with no clinically meaningful differences in safety or effectiveness.
Aflibercept is a treatment for diabetic macular edema (DME) and diabetic retinopathy. The new biosimilar, aflibercept-jbvf (Yesafili), was approved by the U.S. Food and Drug Administration (FDA) in May 2024, but a delay tied to patent litigation kept it off the U.S. market.
The launch gives eye specialists another aflibercept option for diabetes-related eye disease. Biosimilars may also help expand access and lower treatment costs, although insurance coverage and out-of-pocket costs can vary.
What Is Yesafili? Yesafili is an anti-vascular endothelial growth factor (anti-VEGF) treatment given by injection into the eye. As a biosimilar, Yesafili is highly similar to Eylea and has no clinically meaningful differences in safety or effectiveness, according to the FDA.
VEGF is a protein that can cause abnormal blood vessels to grow and leak fluid in the eye. By blocking VEGF, aflibercept products can reduce abnormal blood vessel growth and leakage, helping protect the retina and preserve vision.
The FDA approved Yesafili after reviewing clinical, laboratory, and other scientific evidence. An important part of this review was the INSIGHT phase 3 clinical trial, which included 355 adults with DME. Participants received either Yesafili or Eylea so researchers could compare how well the treatments worked and how safe they were.
Key findings from the trial included:
These results support Yesafili as a highly similar alternative to Eylea for people living with DME.
What Are the Possible Side Effects? Like all treatments, Yesafili can cause side effects. The most common side effects reported with aflibercept products include:
Serious problems can happen after an injection, including endophthalmitis (a serious infection inside the eye), retinal detachment, and retinal vasculitis, which is inflammation of the blood vessels in the retina.
Eye specialists also monitor for increases in eye pressure and a potential risk of blood clots, which can lead to problems such as stroke or heart attack.
