New virus therapy takes on tough bladder cancer

NCT ID NCT07283835

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

Summary

This phase 2 trial is testing a treatment called cretostimogene grenadenorepvec, a modified virus designed to infect and destroy cancer cells, in 16 people with high-risk bladder cancer that has not responded to standard BCG therapy. The study aims to see if the treatment can make tumors disappear and how long that effect lasts. Participants receive the virus directly into the bladder, along with a helper substance to improve its action.

What this could mean

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

Active substance

Cretostimogene grenadenorepvec (a modified virus that targets and kills cancer cells)

What this could lead to

If it works, this could offer a new treatment option for people with bladder cancer that has not responded to standard therapy, potentially delaying or avoiding the need for bladder removal.

What could go wrong

This is a small, early-phase trial with only 16 participants, so results may not apply to everyone. The treatment may cause side effects or fail to control the cancer long-term.
