AMGEN 

Amgen is a leader in biotechnology-based human therapeutics. Flagship drugs include red blood cell boosters Epogen and Aranesp, immune system boosters Neupogen and Neulasta, and Enbrel and Otezla for inflammatory diseases. Amgen introduced its first cancer therapeutic, Vectibix, in 2006 and markets bone-strengthening drugs Prolia/Xgeva (approved 2010) and Evenity (2019). The acquisition of Onyx Pharmaceuticals bolstered the firm's therapeutic oncology portfolio with Kyprolis, which has been further strengthened with the launch of new drugs in blood cancers (Blincyto) and solid tumors (Imdelltra). The 2023 Horizon acquisition brought several rare-disease drugs, including thyroid eye disease drug Tepezza. Amgen also has a growing biosimilar portfolio.
