Can donor immune cells be engineered to fight blood cancer?

NCT ID NCT05391490

First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time

Summary

This trial tests a new type of cell therapy called KCAT19 for people aged 16 to 65 with advanced B-cell blood cancers that have relapsed or not responded to at least two prior treatments. The therapy uses immune cells from a donor's cord blood, which are modified to recognize and attack cancer cells. The study aims to see if these cells can be safely produced and given to patients, and to measure their effects on the cancer.

What this could mean

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

Active substance
KCAT19 T cells, a type of engineered immune cell made from donor cord blood
What this could lead to
If successful, this approach could offer a new treatment option for people with advanced blood cancers that have not responded to standard therapies.
What could go wrong
This is an early-stage trial with a small number of participants. The treatment may cause severe side effects, and it is not yet known if it will be effective or safe for widespread use.
