Can a glowing dye help surgeons see and remove bladder cancer more completely?
NCT ID NCT06972771
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This trial tests a fluorescent dye called TTP-ICG that may help surgeons identify bladder cancer tissue during removal. Researchers will soak resected tissue samples in the dye and use near-infrared imaging to see if cancer glows differently from healthy tissue. The goal is to reduce the chance of leaving cancer behind, which can lead to recurrence. The study involves 40 adults with suspected bladder cancer who are scheduled for surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TTP-ICG incubation solution, a fluorescent dye that targets cancer cells
- What this could lead to
- If it works, this could lead to a method that helps surgeons remove bladder tumors more completely, potentially lowering the chance of cancer coming back.
- What could go wrong
- This is an early, small study on tissue samples, not yet in living patients. The dye may not clearly distinguish cancer from healthy tissue, and more research will be needed.

Who is studied
The investigators plan to enroll 40 patients, who have been suspected bladder cancer scheduled to undergo surgical intervention. Following the surgery, the resected tissues will be incubated with the TTP-ICG solution, and NIR-II fluorescence signals from the tissues will be collected.
