New pill shows promise for Tough-to-Treat bladder cancer

NCT ID NCT04917809

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a pill called erdafitinib in 20 people whose non-muscle invasive bladder cancer has returned after standard treatments like BCG. All participants have a specific change in the FGFR3 gene, which the drug targets. They take the pill for about a month before their scheduled surgery to see if it shrinks or eliminates the tumor.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Erdafitinib (a pill that blocks the FGFR3 protein)
What this could lead to
If successful, this could point toward a new targeted treatment option for people with recurrent bladder cancer that has a specific genetic change (FGFR3 mutation).
What could go wrong
This is a very small, early-phase trial with only 20 participants. It tests a short treatment window before standard surgery, so it is not designed to prove long-term benefit or cure. The drug may cause side effects like high phosphate levels.
