NET-PD is a large multi-faceted effort to find drugs to slow the progression of Parkinson's disease. The first studies tested several compounds; one of these is now being evaluated in a larger clinical trial. Like all U.S. clinical trials, NET-PD is carefully designed to answer questions about new drugs while safeguarding the health of volunteers.

How is NET-PD different from other studies?

Most PD treatment clinical trials focus on treating the symptoms of the disease. NET-PD evaluates agents that have the potential to slow the progression of PD.

A clinical trial is a study of the safety and efficacy of a new drug or other treatment. The NIH Exploratory Trials in Parkinson's Disease (NET-PD) will test several different compounds to learn if any of them can slow the progression of Parkinson's disease.
