Roche is a Swiss healthcare company headquartered in Basel, focused on oncology, immunology, infectious diseases and ophthalmology, with major drugs including Ocrevus for multiple sclerosis, Hemlibra for haemophilia and Tecentriq in cancer.
Roche pioneered personalised medicine by pairing its drugs with its own diagnostics division, though its best-selling oncology and immunology treatments now face growing competition from lower-cost biosimilars.
