Does sipuleucel-t work?
Treatment also resulted in a 21% reduction in the risk of disease progression (P = 0.111). Only seven of the 147 patients (4.8%) in the sipuleucel-T arm had a reduction of 25% or greater in prostate-specific antigen (PSA) levels; however, none of the 78 patients in the placebo group did.
How do you administer PROVENGE?
Administer PROVENGE via intravenous infusion over a period of approximately 60 minutes. Do not use a cell filter. PROVENGE is supplied in a sealed, patient-specific infusion bag; the entire volume of the bag should be infused. Observe the patient for at least 30 minutes following each infusion.
How effective is sipuleucel?
With a median follow-up of 34.1 months and complete survival follow-up data for 99% of patients, treatment with sipuleucel-T resulted in a 4.1-month improvement in median survival and an improvement in the rate of 3-year survival (31.7% for patients receiving sipuleucel-T, as compared with 23.0% for those receiving …
When do you use sipuleucel-T?
A vaccine used to treat prostate cancer that has spread to other parts of the body. It is used in patients who have few or no symptoms and whose cancer is castration resistant (has not responded to treatments that lower testosterone levels).

Sipuleucel-T (Provenge) (Sip-T) is first -in class as a therapeutic autologous vaccine approved for the treatment of men with asymptomatic or minimally symptomatic castrate-resistant metastatic prostate cancer.

To date, sipuleucel-T (an autologous cellular immunotherapy) is the only approved immunotherapy for PC patients.
Is sipuleucel-T a passive immunotherapy agent?

How does sipuleucel work?
Sipuleucel-t is an autologous immunotherapy that activates a man’s immune cells to multiply and attack prostate cancer cells by way of activating certain immune cells with a vaccine that triggers immune cells to identify prostate cancer cells by an antigen that is highly specific to prostate cancer.
