Summary

This phase 2 study tests a drug called AK104, which helps the immune system attack cancer cells, in people with specific types of stomach or colorectal cancer. Participants receive the drug before and after surgery to see if it can completely eliminate the tumor. The trial involves 47 patients and focuses on safety and how well the drug works.

What this could mean

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

Active substance

AK104 (a bispecific antibody targeting PD-1 and CTLA-4)

What this could lead to

If successful, this could lead to a new treatment option that improves the chance of eliminating tumors before and after surgery for certain gastric and colorectal cancers.

What could go wrong

This is an early-phase trial with only 47 participants, so results may not apply to everyone. The treatment may cause side effects from immune system activation, and it's not yet proven to be better than standard care.
