Engineered immune cells take aim at stubborn cancers

NCT ID NCT03190941

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new therapy where a person's own white blood cells are collected, genetically modified in a lab to recognize and attack cancer cells with a specific mutation (KRAS G12V), and then infused back. Participants also receive chemotherapy and a drug to boost cell activity. The goal is to see if this treatment can shrink tumors in adults with pancreatic, gastric, colon, or rectal cancers that have this mutation.

What this could mean

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

Active substance

genetically modified immune cells (anti-KRAS G12V mTCR cells)

What this could lead to

If it works, this could offer a new treatment option for people with certain hard-to-treat cancers that have the KRAS G12V mutation.

What could go wrong

This is an early-phase trial with only 110 participants, so it may not work for everyone. The chemotherapy and cell infusion can cause serious side effects like low blood counts and infections.
