Immunotherapy for Prostate Cancer

Immunotherapies use the power of your immune system to fight your cancer. Vaccines are one form of immunotherapy. Sipuleucel-T is a vaccine used for advanced, metastatic prostate cancer if:

  • It no longer responds to hormone therapy (sometimes called castration-resistant disease)
  • It is causing few or no symptoms

Another kind of immunotherapy, called an immune checkpoint inhibitor, may also be used in a small subset of men with advanced prostate cancer. These medicines include pembrolizumab and dostarlimab.

How Immunotherapy Can Treat Prostate Cancer

Sipuleucel-T is made from your own immune cells. Your care team collects your white blood cells and sends them to a specialized facility. There, a team activates your cells by exposing them to a protein found in most prostate cancers (prostatic acid phosphatase). This is linked to a protein that stimulates the immune system. The goal is to enhance the response of your immune cells against the cancer. Then your treated immune cells are returned to the clinic and infused into your bloodstream.

Pembrolizumab and dostarlimab may help if your prostate cancer cells have certain genetic changes. These medicines can help your immune system see your cancer cells and destroy them.

Why Choose Fred Hutch for Immunotherapy for Prostate Cancer 

Fred Hutch Cancer Center is a leader in developing immunotherapies and giving patients early access through clinical trials. Fred Hutch was the site for several of the studies that led to approval of sipuleucel-T by the U.S. Food and Drug Administration.

We’re actively working on clinical trials of immunotherapy agents, like more immune checkpoint inhibitors and cellular immunotherapy, already used for some other cancers.

Immunotherapy for Prostate Cancer FAQ

Sipuleucel-T is given by infusion. For an infusion, liquid medicine is put into a vein through an intravenous (IV) line. You will get three doses, each about two weeks apart.

Pembrolizumab and dostarlimab are given by infusion in cycles. Your medical oncologist will talk with you about the schedule that’s right for your situation. A common schedule is every three to six weeks.
