PROVENGE® + Sipuleucel-T for Metastatic Castrate-Resistant Prostate Cancer

This study is looking at men with metastatic castrate-resistant prostate cancer (mCRPC), which is prostate cancer that has spread and no longer responds to hormone therapy. It's testing if a single booster infusion of Sipuleucel-T, an immunotherapy, can improve the immune response in patients who have already received PROVENGE®. The main goal is to see how the immune system reacts to specific proteins (PAP and PA2024) after this booster. You might be able to join if you are a man aged 18 or older, have mCRPC that is asymptomatic or minimally symptomatic, and have already qualified for and received PROVENGE® treatment. The study is currently recruiting patients.

Study design
This is an open-label study, meaning both you and your doctors will know which treatment you are receiving. It plans to enroll 400 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your immune response will be measured after the booster infusion, and you will be followed for overall survival for up to 5 years.

  • Assess humoral immune response to PAP and PA2024 after booster infusionOnce all subjects have completed the study through the 5 year Overall Survival Period

    To assess the humoral response ((i.e. antibody titer) to PAP and PA2024 after booster infusion in subjects with metastatic castrate-resistant prostate cancer who have received a single booster dose of sipuleucel-T vs those subjects who have not
