| Description | 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. |
| Indication/Disease | Sipuleucel-T is an autologous cellular immunotherapy indicated for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant (hormone refractory) prostate cancer. |
| Pharmacodynamics | NA |
| Mechanism of Action | Sipuleucel-T is designed to induce an immune response targeted against PAP, an antigen expressed in most prostate cancers. During ex vivo culture with PAP-GM-CSF, APCs take up and process the recombinant target antigen into small peptides that are then displayed on the APC surface. The precise mechanism remains unknown, however. |
