Study Summary

This trial studies if a new treatment for prostate cancer works better than existing treatment alone.

Who is the study for?
This trial is for men over 18 with metastatic prostate cancer that's not causing severe symptoms. They must be on hormone therapy and have a rising PSA level but no new cancer spread on scans. Participants need good organ function, controlled HIV if present, and can't have had recent chemotherapy or radiotherapy, prior Sipuleucel-T treatment, significant heart issues, or other serious illnesses.Check my eligibility
What is being tested?
The study tests whether combining Sipuleucel-T (Provenge) with new hormonal agents like abiraterone, enzalutamide, or apalutamide improves immune system activation in men with advanced prostate cancer without visceral metastases. It aims to see if this combination can better target the cancer cells.See study design
What are the potential side effects?
Sipuleucel-T may cause flu-like symptoms such as fever and chills; back pain; joint ache; nausea; headache. Hormonal agents might lead to fatigue; hot flashes; high blood pressure; liver issues and could affect mood or sexual function.
