New cancer cocktail aims to rev up immune system against tumors

NCT ID NCT05651022

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

Summary

This early-stage trial tests a new drug called DECOY20, which is designed to wake up the immune system to fight cancer. It is being tested alone or with another drug (tislelizumab) in 120 adults with advanced solid tumors like liver, lung, or colorectal cancer. The main goals are to check safety, find the right dose, and see if the treatment can control the disease.

What this could mean

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

Active substance
DECOY20 (a cancer immunotherapy that activates the immune system) and tislelizumab (a drug that helps immune cells attack cancer)
What this could lead to
If it works, this could point toward a new treatment option for several advanced cancers that are hard to treat.
What could go wrong
This is an early phase 1/2 trial with only 120 people, so it is mainly checking safety and dosing. The treatment may not shrink tumors or could cause side effects like immune reactions.
