Could stem cells ease Parkinson's? new trial tests hope
NCT ID NCT04995081
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tested whether infusions of stem cells (HB-adMSCs) from healthy donors could help people with Parkinson's disease. 60 participants received either the stem cells or a placebo (salt water) to see if the treatment improved movement and daily living. The study is complete, and results will show if this approach is safe and effective enough to pursue further.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Allogeneic adipose-derived mesenchymal stem cells (HB-adMSCs)
What this could lead to
If it works, this could point toward a new way to slow or improve motor symptoms in Parkinson's disease, potentially reducing disability.
What could go wrong
This is a small, early-phase (phase 2) study with only 60 people. Results may not apply to everyone, and stem cell treatments carry risks like immune reactions or unknown long-term effects.
