What is SpaceOAR® Hydrogel?

SpaceOAR hydrogel is an option for men who undergo radiation treatment for prostate cancer. It acts as a spacer providing space between the rectum and the prostate, making it much less likely that the rectum is exposed to radiation. It is injected into place prior to the start of radiation treatment. Patients may be awake or asleep under general anesthesia for the procedure. SpaceOAR hydrogel is not painful, remains stable during radiation therapy and then is gradually absorbed by the body after radiation therapy has been completed.

Clinical trials in Europe and the U.S. have demonstrated that the hydrogel is safe and that the space created significantly reduces the radiation delivered to the rectum.  The randomized SpaceOAR hydrogel U.S. Clinical Trial found that patients who received the hydrogel spacer reported significantly less rectal pain during radiotherapy and had significantly less severe long-term rectal complications.

Results from the randomized clinical trial demonstrated the following:

✓ Bowel: 66% fewer SpaceOAR hydrogel patients experienced clinically significant declines in detectable bowel quality of life (1X the Minimal Important Difference)2
✓ Urinary: 65% fewer SpaceOAR hydrogel patients experienced clinically significant declines (2X the Minimal Important Difference) in detectable urinary quality of life2
✓ Sexual: SpaceOAR hydrogel patients who had erections sufficient for intercourse at baseline were 78% more likely to retain sexual function at 3 years3
