Approved drug Immunopharmacology Ligand
eculizumab is an approved drug (FDA (2011), EMA (2007))
Compound class: Antibody
Comment: Eculizumab is a humanized monoclonal antibody targeting terminal complement activation, by binding to complement component C5 and inhibiting the production of C5a [4]. It is the first approved therapy for paroxysmal nocturnal hemoglobinuria.
Eculizumab's developers, Alexion Pharmaceuticals have developed a next-generation version of eculizumab called ravulizumab (ALXN1210; FDA approved in December 2018), that has a longer circulating half-life than the originator, which allows for monthly dosing.
The evidence confirming C5, C5a and the C5a receptor as anti-inflammatory and anti-cancer drug targets is reviewed by Horiuchi and Tsukamoto (2016) [2].

Amgen's biosimilar ABP 959 (eculizumab-aeeb; Bekemv®) was approved by the EMA in April 2023. This was approved as an interchangeable biosimilar to Soliris® by the FDA in May 2024.
Samsung Bioepis' biosimilar (SB12; Epysqli®) was approved by the EMA in May 2023.
BOW080 (Polpharma Biologics, formerly Epirus Biopharmaceuticals) was in development, but this project appears to have been discontinued.
