Read our Prostate Cancer research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing the SpaceOAR Vue System — a biocompatible gel that is injected between the prostate and rectum before radiation therapy. The goal is to see if this spacer can reduce side effects to the bowel that sometimes happen after radiation treatment for prostate cancer. Researchers will compare men who receive radiation with the gel spacer to men who receive radiation without it.
Radiation therapy is an effective treatment for prostate cancer, but the radiation can sometimes damage the bowel tissue nearby, causing long-term digestive problems. This trial is designed to test whether this treatment can create a protective barrier that reduces those side effects.
If you join this study, you will be randomly assigned to receive either the standard radiation therapy alone or radiation therapy after the SpaceOAR Vue gel is injected. The gel injection is a brief outpatient procedure done before your radiation treatments begin. You will then receive your planned radiation therapy over several weeks, and the research team will monitor you for side effects over time, especially any bowel-related symptoms.
