Pioneering the future of immunotherapy

Founded on the belief that immunotherapy made from a patient’s own cells will transform cancer treatment, Dendreon is fighting for patients by making the battle against cancer personal. By harnessing the power of the body’s immune system, we help extend the lives of patients battling cancer.

Our flagship product, PROVENGE® (sipuleucel-T), was the first FDA-approved immunotherapy made from a patient’s own immune cells. Since its approval in 2010, nearly 40,000 men with advanced prostate cancer have been prescribed PROVENGE. Today, we continue to push our research forward so that we may help even more patients fight cancer with personalized immunotherapy.
