New cocktail of cancer drugs tested for tough bladder tumors
NCT ID NCT06483334
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study is testing a combination of three drugs—sacituzumab tirumotecan, enfortumab vedotin, and pembrolizumab—in people with advanced bladder cancer that has spread or cannot be surgically removed. The trial has two parts: first, to find safe doses of the two-drug combo, and second, to see if adding a third drug (pembrolizumab) is safe and effective. About 38 participants will be enrolled. The main goals are to check for side effects and to see if tumors shrink.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Sacituzumab tirumotecan (MK-2870), enfortumab vedotin (EV), and pembrolizumab (Keytruda)
What this could lead to
If this works, it could point toward a more effective treatment option for people with advanced bladder cancer that has spread or cannot be removed by surgery.
What could go wrong
This is a very early, small study (Phase 1/2) with only 38 participants. The main goal is safety, not yet proof of effectiveness. Side effects from combining these strong drugs could be significant, and the treatment may not work for everyone.
