Sipuleucel-T

Sipuleucel-T is a personalized, autologous, cellular immunotherapy. Sipuleucel-T is a therapeutic cancer vaccine for prostate cancer. Sipuleucel-T selectively targets the prostate-specific antigen (PSA) known as prostatic acid phosphatase (PAP) that is expressed in around 95% of prostate cancers. It must be prepared specifically for each patient. In metastatic prostate cancer, it has extended survival by median 4.1 months (IMPACT Phase III trial data). Sipuleucel-T is marketed under the brand name Provenge by Dendreon Corporation. Sipuleucel-T was approved by the U.S. Food and Drug Administration (FDA) on April 29, 2010, to treat asymptomatic or minimally symptomatic metastatic Hormone-Refractory Prostate Cancer (HRPC). The treatment initially cost $93,000 at the time of FDA approval, but rose to over $100,000 in 2014.
