NCT ID NCT07312110
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether D-serine, a dietary supplement, can slow the progression of Parkinson's disease. One hundred people with early-stage Parkinson's will receive either D-serine or a placebo for 58 weeks. Researchers will measure changes in symptoms and brain scans to see if D-serine protects nerve cells and improves quality of life.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
D-serine (a dietary supplement)
What this could lead to
If it works, this could point toward a treatment that slows Parkinson's progression and reduces symptoms, helping people live better longer.
What could go wrong
This is an early Phase 2 trial with only 100 people. It may fail to show benefit, and D-serine might not work for everyone. Side effects are possible, though previous studies suggest it is safe.
