Amgen Inc.
A biotechnology company that makes medicines for serious illnesses, including the bone-strengthening drug Prolia, the cholesterol-lowering injection Repatha, and the psoriasis treatment Otezla, sold to patients and doctors worldwide. It was founded in 1980 in Thousand Oaks, California, as Applied Molecular Genetics, a name later shortened to "Amgen." Its first CEO famously ran the company from a small trailer so scientists could use the office space, and early experiments included trying to extract oil from shale and accelerate chicken growth.
