New drug aims to outsmart resistant colorectal cancer

NCT ID NCT05426005

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This trial tests a new drug called Cadonilimab in 28 people with advanced colorectal cancer that has not responded to standard immunotherapy. The drug is a bispecific antibody that targets two immune checkpoints (PD-1 and CTLA-4) to potentially reactivate the immune system against tumors. The main goal is to see how many patients have their tumors shrink or stop growing for at least 12 months.

What this could mean

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

Active substance
Cadonilimab (a bispecific antibody targeting PD-1 and CTLA-4)
What this could lead to
If successful, this could offer a new treatment option for people with advanced colorectal cancer whose tumors have stopped responding to current immunotherapies.
What could go wrong
This is an early-phase trial with only 28 participants, so results may not apply broadly. The drug may not work or could cause significant side effects.
