What is Cimerli?

Cimerli is a prescription medicine that is injected by intravitreal injection into the eye once a month. It is used to prevent vision loss or blindness in certain eye conditions that cause fluid to leak into the macula, including wet age-related macular degeneration resulting from the growth of abnormal blood vessels, and macular edema.

Cimerli is made from a human antibody fragment. It works by inhibiting the biologic activity of human vascular endothelial growth factor A (VEGF-A), a protein that is thought to play an important role in the formation of new blood vessels. 

Cimerli is the second approved biosimilar to Lucentis (ranibizumab), but is the first interchangeable biosimilar, which means it may be substituted for Lucentis without consulting the prescriber.

What is Cimerli used for?

Cimerli is used to treat neovascular (wet) age-related macular degeneration (AMD), which occurs when abnormal blood vessels grow under the macula and retina in the eye.

Cimerli is used to treat macular edema (swelling) caused by diabetes or by a blockage in the blood vessels. it is also used to treat diabetic retinopathy, the most common cause of vision loss in people with diabetes.

Cimerli is also used to treat myopic choroidal neovascularization (mCNV), a complication of severe near-sightedness that can lead to blindness.

Cimerli may also be used for purposes not listed in this medication guide.
