Robert A. Bradway has served as Chairman and Chief Executive Officer of Amgen since 2012, overseeing the company’s evolution into a global biotechnology leader with a durable and strategically differentiated oncology presence. Under his leadership, Amgen established oncology as a core application of its biologics expertise, prioritizing immune-engaging platforms, targeted cancer biology, and translational research over broad portfolio expansion. This approach positioned Amgen as a long-term contributor to oncology innovation.
During Bradway’s tenure, Amgen achieved several field-level milestones in cancer, including advancing biologics-based immune engagement into scalable development platforms and delivering one of the earliest successful clinical breakthroughs against a historically “undruggable” cancer target – an achievement widely regarded as an inflection point in precision oncology. He also reinforced Amgen’s backbone in hematologic malignancies by sustaining investment in discovery, clinical development, and manufacturing capabilities required for complex biologic cancer therapies. These outcomes reflect CEO-level decisions emphasizing scientific selectivity, execution discipline, and long-term oncology impact. Before becoming CEO, Bradway served as Amgen’s Chief Financial Officer and Chief Operating Officer, bringing capital discipline and governance rigor to oncology investment decisions.
