New drug cocktail targets Hard-to-Treat bladder cancer

NCT ID NCT04963153

First seen Jun 25, 2026 · Last updated Jul 31, 2026 · Updated 2 times

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.
