NCT ID NCT04689594
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a treatment using a sheet of the patient's own mouth cells to prevent the esophagus from narrowing after cancer removal surgery. Only one person took part before the study was stopped early. The goal was to see if the cell sheet could safely reduce scarring and keep the esophagus open.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Human (autologous) oral mucosal cell sheet
What this could lead to
If it works, this could offer a way to prevent esophageal narrowing after cancer surgery, reducing the need for repeated procedures.
What could go wrong
The trial was terminated early with only 1 participant, so results are very limited. It is unclear if the treatment is effective or safe in a larger group.
