Clinical trial for Castration Levels of Testosterone
Official title Standard Systemic Therapy With or Without Definitive Treatment in Treating Participants With Metastatic Prostate Cancer
ClinicalTrials.gov ID: NCT03678025
What this study is testing
What is Abiraterone?
This is an investigational oral medicine being studied to see if it helps treat prostate cancer that has spread to other parts of the body. It is designed to block the body from making certain hormones that can help prostate cancer grow.
Also referred to as CB 7598.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see whether combining surgery or radiation with usual systemic treatment can reduce the chance of the cancer growing or spreading.
- Who it's for
- Men whose prostate cancer has spread to other parts of the body and is at stage IV.
- What's involved
- Participants will receive standard systemic therapy and may also have prostate removal surgery or radiation therapy. They will attend regular visits and undergo tests to monitor the cancer.
- Time commitment
- The trial lasts about 2–3 years, with multiple clinic visits and tests scheduled throughout the study period.
- Phase 3: a large, late-stage study
- Which group you join is decided by chance.
