Hydrogel could starve tumors by cutting off their blood supply

NCT ID NCT04523350

First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time

Summary

This study tests a new liquid gel called Instylla HES that is injected into blood vessels feeding hypervascular tumors (tumors with many blood vessels). The gel hardens to block blood flow, starving the tumor. Researchers compare it to standard embolization treatments in about 150 adults with liver, kidney, or other hypervascular tumors. The goal is to see if the gel works as well as standard care and has an acceptable safety profile.

What this could mean

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

Active substance

Instylla Hydrogel Embolic System (a liquid gel that blocks blood vessels)

What this could lead to

If successful, this hydrogel could offer a simpler, more consistent way to cut off blood supply to tumors, potentially improving outcomes for people with liver, kidney, or other hypervascular cancers.

What could go wrong

This is a mid-stage trial with 150 participants, so results may not apply to everyone. The hydrogel is new, and there is a risk of serious side effects like unintended blockage or damage to nearby tissues.
