- NCT07151378RecruitingPhase 3
Intestinal gel for Parkinson's mood and behavior problems
This trial tests a gel form of levodopa (called Lecigon) given through a tube into the intestine to see if it helps reduce mood swings, impulsive behaviors, and other mental side effects in people with Parkinson's who already have motor fluctuations. It is for people who have had Parkinson's for at least 5 years and are between 18 and 75 years old.

Silymarin for nerve protection and symptom control in Parkinson's
This trial tests if silymarin, a natural plant extract, can help protect nerves and improve symptoms in people with Parkinson's disease who are already taking dopamine replacement therapy. It aims to see if adding silymarin can provide extra benefits.
