AMGN vs GILD Comparison

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. Recent launches include Repatha (cholesterol-lowering), Aimovig (migraine), Lumakras (lung cancer), and Tezspire (asthma). The 2023 Horizon acquisition brought several rare-disease drugs, including thyroid eye disease drug Tepezza. Amgen also has a growing biosimilar portfolio.

Gilead Sciences develops and markets therapies to treat and prevent life-threatening infectious diseases, with the core of its portfolio focused on HIV and hepatitis B and C. Gilead's acquisition of Pharmasset brought rights to hepatitis C drug Sovaldi, which is also part of newer combination regimens that remain standards of care. Gilead is also growing its presence in the oncology market via acquisitions, led by CAR-T cell therapy Yescarta/Tecartus (from Kite) and breast and bladder cancer therapy Trodelvy (from Immunomedics).
