Stem cells injected into brain to fight Parkinson's

NCT ID NCT05635409

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This first-in-human trial tests a stem cell therapy called STEM-PD for Parkinson's disease. Eight participants with moderate Parkinson's will have dopamine-producing cells transplanted into a brain region affected by the disease. The main goal is to check safety over 12 months, with follow-up for 3 years. Researchers also look for early signs that the treatment might improve symptoms.

What this could mean

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

Active substance

STEM-PD product (dopaminergic progenitor cells from human embryonic stem cells)

What this could lead to

If it works, this could point toward a treatment that repairs damaged brain cells in Parkinson's disease, potentially reducing the need for daily medication.

What could go wrong

This is a very early, small trial (8 people) focused on safety, not effectiveness. The stem cells may not survive or could cause side effects like brain swelling or abnormal growths.
