Mechanism of Action for PF582: Biosimilar to Ranibizumab (Lucentis®)
Wet AMD arises from abnormal growth of blood vessels, resulting in retinal
damage
Ranibizumab inhibits choroidal neovascularization by blocking VEGF-A
RPE: Retinal pigment epitheliumCNV: Choroidal neovascularization

Generics and Biosimilars: Contrasting Impact on the Healthcare System
Generic drugs now account for >80% of all prescriptions in the US.
In contrast, the first biosimilar was just approved by the FDA in 2015.
Why is there such a large discrepancy?
