Dendreon Corporation is a biotechnology company focused on developing immunotherapies to treat cancer. It currently has one product, Provenge, approved for treating advanced prostate cancer. Provenge harnesses the power of the immune system by using a patient's own immune cells to fight cancer cells. Clinical trials showed Provenge increased survival rates by 22% in treated patients compared to the control group. However, Dendreon faces challenges of gaining FDA approval for additional indications and managing costs of manufacturing and distributing its complex cellular immunotherapy.
