Empowering the immune system to detect and attack cancer cells

Our flagship product, PROVENGE, is a unique kind of cancer immunotherapy.

Watch this video to learn how it works.

PROVENGE reprograms the body’s own immune cells to detect and attack cancer cells, with little impact to healthy tissue or cells.

Additionally, PROVENGE may enable the immune system to fight prostate cancer cells as they change. This is because cancer cells that have been destroyed release identifying information into the bloodstream, which the immune system is trained to recognize and attack, should prostate cancer cells reappear.

In both clinical and real-world settings, PROVENGE has been proven to increase overall survival.

PROVENGE® (sipuleucel-T)

PROVENGE has been available in the United States since 2010. It is the first and only FDA-approved immunotherapy for the treatment of advanced prostate cancer made from a patient’s own immune cells.

This groundbreaking treatment has been prescribed to nearly 40,000 men with advanced prostate cancer, helping many live longer.

ProVent Info
About the ProVent Study

The life-saving effects of immunotherapy treatment with sipuleucel-T have been proven in some men with advanced prostate cancer (also referred to as metastatic castrate-resistant prostate cancer or mCRPC), and research suggests that this cutting-edge therapy may also benefit men with lower risk prostate cancer who are on active surveillance (AS).

Nearly 175,000 men are diagnosed with prostate cancer every year.[i] Of these, about 30 to 40% with a lower risk of prostate cancer will opt for AS[ii]. A new study will evaluate the effectiveness of sipuleucel-T in reducing disease progression in men who are candidates for AS and looking for a proactive alternative to surgery or radiation.

AS has grown in popularity as a treatment option for men with lower risk prostate cancer and includes regular prostate-specific antigen (PSA) testing and tumor biopsies (every 1-2 years) to ensure the cancer is not growing or spreading. Choosing AS may allow some men to delay – or even avoid – surgery and radiation, which often result in life-altering side effects.[iii]

ProVent Study Details (NCT03686683)


Phase 3 clinical trial evaluating the effectiveness of immunotherapy (sipuleucel-T) in reducing disease progression in men with lower risk prostate cancer on AS.


The investigational ProVent study will enroll 450 men in the U.S. age 18 or older diagnosed with lower risk prostate cancer within 12 months of enrollment.


Study participants will be randomized 2:1. This means that for every 2 participants that receive sipuleucel-T, 1 will receive the standard treatment protocol for AS.


Sipuleucel-T uses a patient’s own cells trained to stimulate the body’s immune system to target and attack the prostate cancer cells.

You will get PROVENGE in 3 intravenous infusions (put into your veins), about 2 weeks apart. Each infusion takes about 60 minutes. You will then be monitored for at least 30 minutes. Your doctor will give you a schedule for your cell collection and infusion appointments. It is very important that you arrive on time for your appointments
  • The most common side effects of PROVENGE include chills, fatigue, fever, back pain, nausea, joint ache, and headache. These are not all the possible side effects of PROVENGE treatment
  • PROVENGE infusion can cause serious reactions. Tell your doctor right away if you:

    • Get a fever over 100?, or redness or pain at the infusion or collections sites. Any of these may be signs of infection
  • Tell your doctor about any side effect that concerns you or does not go away. For more information, talk with your doctor
