Placenta cell therapy shows promise for tough transplant complication

NCT ID NCT04118556

First seen May 20, 2026 · Last updated Jun 22, 2026 · Updated 4 times

Summary

This trial tested a treatment made from placenta cells (called decidua stroma cells) in 12 adults who had severe graft-versus-host disease (GVHD) after a stem cell transplant and did not respond to steroids. Patients received two doses of the cells or the best available standard therapy. The goal was to see if the cell treatment was safe and could improve outcomes by day 56.

What this could mean

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

Active substance

placenta-derived decidua stroma cells (DSC)

What this could lead to

If it works, this could offer a new treatment option for patients with severe graft-versus-host disease that does not respond to steroids.

What could go wrong

This is a small, early-phase trial (only 12 patients) that was terminated, so results are limited. The treatment may not work better than existing options and carries risks like infection or infusion reactions.
