Summary

This study tests a dye called indocyanine green that is injected into the blood before surgery. The dye makes tumors glow under a special camera, helping surgeons see and remove cancer that might otherwise be missed. The trial includes 500 adults with solid tumors who are scheduled for surgery. The goal is to find the best dose and timing, and to see if the dye improves how completely the cancer is removed.

What this could mean

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

Active substance
indocyanine green (a dye injected into the blood before surgery)
What this could lead to
If it works, this dye could help surgeons see and remove more cancer during surgery, potentially reducing the chance of cancer coming back.
What could go wrong
This is an early-phase trial (Phase 1/2) testing safety and best dosing, so it is not yet proven to improve outcomes. The dye may not work well for all tumor types, and there is a small risk of allergic reaction or side effects from the dye.
