PulseNews reported that Samsung Bioepis has received approval for Episcli® (SB12), biosimilar to Alexion’s Soliris® (eculizumab), from the Korean Ministry of Food and Drug Safety. Episcli® is approved to treat nocturnal hemoglobinuria.
On 3 January 2024 Alexion sued Samsung Bioepis in the US District Court for the District of Delaware asserting infringement of six of its eculizumab patents.
