Read our Bladder Cancer research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing a medication called dutasteride to see if it can help prevent bladder cancer from coming back in people with low-grade non-muscle invasive bladder cancer. You would take this medication as a pill once daily for up to two years. The study wants to understand whether this medication is safe and effective, and whether it might help reduce the chances of your cancer returning.
Low-grade bladder cancer often comes back after initial treatment, which means many patients need repeat procedures and monitoring. Researchers believe this medication might help prevent these recurrences, but they need to test it carefully in people to confirm it works and is safe.

You would take one tablet of the medication by mouth every single day for up to two years, or until your cancer comes back (whichever is sooner). You would attend regular follow-up appointments where your doctor monitors your bladder and checks for cancer recurrence using standard surveillance methods. If your cancer does return during the study, you would have the option to continue taking the medication for the full two-year period if you choose to do so.
