New drug cocktail targets Hard-to-Treat bladder cancer

NCT ID NCT04963153

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial is testing a combination of two drugs—erdafitinib and enfortumab vedotin—in 24 people with advanced bladder cancer that has spread and has specific FGFR2/3 gene changes. Erdafitinib blocks a faulty protein that helps cancer grow, while enfortumab vedotin delivers a toxin directly to cancer cells. The main goals are to find the safest dose and see if the combination can shrink tumors.

What this could lead to

If this combination works, it could offer a new treatment option for people with advanced bladder cancer that has specific genetic changes.

What could go wrong

This is a very early phase 1 trial with only 24 participants, so it is mainly checking safety and dosing. The combination may not shrink tumors or could cause significant side effects.
