Ranibizumab is a monoclonal antibody fragment created from the same parent mouse antibody as bevacizumab. It inhibits angiogenesis (the formation of new blood vessels) by inhibiting vascular endothelial growth factor A (VEGF-A). Ranibizumab can be used to treat macular degeneration by inhibiting VEGF, which is responsible for the excessive formation of blood vessels in the retina leading to progressive loss of vision. The monoclonal antibody drug is indicated for the treatment of wet age-related macular degeneration (AMD), macular oedema, degenerative myopia and diabetes complications; all conditions of the eye causing vision loss [1]. 

Lucentis is the originator product developed by Roche (Genentech) and is a blockbuster drug with global revenue of around US$3.4 billion in 2021, with just over 40% of sales in the US [2]. The originator’s US patent expired in June 2020 and the European patent is expiring in 2022 [3].  

Ximluci positive opinion in Europe
Ximluci has been recommended for approval in the European Union (EU) for the treatment of wet AMD, diabetic macular oedema (DME), diabetic retinopathy (PDR), retinal vein occlusion (RVO) and visual impairment due to choroidal neovascularization (CNV). The positive opinion will now be referred to the European Commission (EC) and a decision will be made on whether to grant marketing approval.

Cimerli US launch
Cimerli (also known as Ranivisio, Ongavia, FYB201 and CHS-201) was developed by Swiss biotechnology company Bioeq, a joint venture between Poland-based Polpharma Biologics and Germany-based Formycon [4]. 

US-based Coherus acquired rights to commercialize Bioeq’s ranibizumab biosimilar in the US in 2019 [5].

Cimerli (ranibizumab-eqrn) is the first interchangeable ranibizumab biosimilar approved by the US Food and Drug Administration for the treatment of neovascular (wet) (nAMD) and other serious retinal diseases. This covers all five indications of the originator biological Lucentis and includes diabetic macular oedema, diabetic retinopathy, macular oedema following retinal vein occlusion and myopic choroidal neovascularization [4].

The product has also been approved in Europe under the name Ranivisio [6] and in the UK as Ongavia [7].
